As a result, it is possible to reduce power consumption while preventing the light from turning off.

JP 2001-291418 A

However, in patent document 1, the sensor is attached to the lighting fixture side. Therefore, if it is going to perform lighting control by a human detection sensor in existing facilities, construction which removes an existing lighting fixture and attaches a lighting fixture of patent document 1 is needed. Further, Patent Document 1 only discloses a substantially straight tubular lamp, and there is no disclosure of a light bulb-shaped lamp.

This invention is made in view of said subject, and it aims at providing a lightbulb-shaped lamp with a lighting control function which can be installed easily.

A bulb-shaped lamp according to an aspect of the present invention includes a base mounted on a socket of a lighting fixture, a lamp body rotatably mounted on the base, around an axial center of the base, and a sensor for detecting a detection target And a light emitting element held by the lamp body and lit in response to detection of the detection target by the sensor. And the said sensor is attached to the said lamp main body so that the detection range of the said sensor may become asymmetrical with respect to the axial center of the said nozzle | cap | die.

As one example, the lamp body holds the light emitting element such that the light transmitting glove has a light emitting direction and the main emission direction faces the direction of the glove, and a housing disposed between the glove and the mouthpiece It consists of The housing may be attached to the base so as to be rotatable about an axis of the base.

As another example, the lamp body holds the light emitting element such that the light transmitting glove has a light emitting direction and the main emission direction faces the direction of the glove, and the case is disposed between the glove and the mouthpiece. It may be composed of the body. The housing may be fixed to the base, and the globe may be rotatably attached to the housing about an axial center of the base.

As an example, the sensor may be attached to the glove such that the sensor is on the axis of the base and the central axis of the detection range is inclined with respect to the axis of the base.

As another example, the sensor may be configured of a detection element and a lens for condensing external light on the detection element, and may be attached to the globe on the axis of the base. And the said lens may be comprised so that the condensing range of external light may become asymmetrical with respect to the axial center of the said nozzle | cap | die.

As still another example, the sensor may be attached to the lamp body at a position off the axial center of the base.

For example, the light emitting element may be a light emitting diode (LED).

(Findings that formed the basis of the present invention)
As a method of solving the said conventional subject, it is possible to attach a sensor to a light bulb shaped lamp itself. However, fixing the sensor to the light bulb shaped lamp causes a new problem that the detection range of the sensor can not be adaptively adjusted according to the usage environment of the light bulb shaped lamp.

Then, in order to solve such a subject, the lightbulb-shaped lamp which concerns on one form of this invention is rotatably attached to the base | base mounted | worn with the socket of a lighting fixture, and the said base so that the axial center of the said base can be rotated A lamp body, a sensor for detecting a detection target, and a light emitting element held by the lamp body and lit in response to detection of the detection target by the sensor. And the said sensor is attached to the said lamp main body so that the detection range of the said sensor may become asymmetrical with respect to the axial center of the said nozzle | cap | die.

Hereinafter, a light bulb shaped lamp according to an embodiment of the present invention will be specifically described with reference to the drawings. Note that all the embodiments described below show general or specific examples. Numerical values, shapes, materials, components, arrangement positions and connection forms of the components, and the like shown in the following embodiments are merely examples, and are not intended to limit the present invention. Further, among the components in the following embodiments, components not described in the independent claim indicating the highest concept are described as arbitrary components.

FIG. 1 is a perspective view of a light bulb shaped lamp 100 according to an embodiment of the present invention. FIG. 2 is a partially cutaway side view of the light bulb shaped lamp 100 of FIG. FIG. 3 is an exploded perspective view of the housing 120, the circuit holder 122, and the base 130. FIG. 4 is a plan view of the semiconductor light emitting module 140.

The bulb-shaped lamp 100 mainly includes a glove 110, a housing 120, a base 130, a semiconductor light emitting module 140, and a sensor 150, as shown in FIG. In the present specification, the glove 110 and the housing 120 may be collectively referred to as a “lamp main body”.

(The glove 110)
The globe 110 is a hemispherical-shaped translucent cover for emitting the light emitted from the semiconductor light emitting module 140 to the outside of the lamp. That is, the light emitted from the light emitting module passes through the globe 110 and is extracted to the outside.

The globe 110 has a shape that simulates a bulb of an A-shaped bulb that is a general bulb shape, and is attached by pressing the opening side end of the globe 110 into the upper side end of the housing 120. In addition, the shape of the glove | globe 110 is not limited to the shape which imitated the bulb | bulb of a A-type light bulb, Any shape may be sufficient. The glove 110 may be fixed to the housing 120 by an adhesive or the like.

Furthermore, it is preferable that the globe 110 be subjected to a diffusion process for diffusing the light emitted from the semiconductor light emitting module 140. For example, by forming a light diffusion film (light diffusion layer) on the inner surface or the outer surface of the globe 110, the globe 110 can have a light diffusion function. Specifically, the light diffusion film can be formed by applying a resin containing a light diffusion material such as silica or calcium carbonate, a white pigment, or the like on the entire inner surface or outer surface of the glove 110. Alternatively, the light diffusion function can be given to the globe 110 by forming light diffusion dots on the globe 110. For example, by processing the surface of the resin-made globe 110, the globe 110 can have a light diffusing function by forming a plurality of dots or forming minute dimples. In addition, the light diffusion function can be provided by embossing the globe 110 as well.

Although glove 110 concerning this embodiment is hemispherical shape, the present invention is not limited to this. The shape of the globe 110 may be, for example, a spheroid or a spheroid. Although the material of the glove 110 is not particularly limited, for example, a glass material or a resin material such as a synthetic resin can be adopted.

(Case 120)
The housing 120 is configured of a main body portion 120 a located on the glove 110 side and a base end portion 120 b located on the cap 130 side. In addition, the housing 120 holds the base 121 holding the semiconductor light emitting module 140 and the circuit holder 122 holding the circuit unit 123 inside. More specifically, the housing 120 holds the semiconductor light emitting module 140 such that the main emission direction of the semiconductor light emitting device 142 described later faces the globe 110.

The main body 120a has a frusto-conical shape whose diameter gradually increases from the base end 120b toward the globe 110, and one end (small diameter side) is connected to the base end 120b, and the other end (large diameter side) ) Is open. Then, the glove 110 is pressed into the opening of the main body portion 120a. The base end 120b is a truncated cone whose diameter gradually increases from the base 130 toward the main body 120a, and one end (small diameter side) is open and the other end (large diameter side) is the main body 120a. It is connected to the. The circuit holder 122 is connected to the opening of the base end 120b as described later with reference to FIG.

The housing 120 is preferably made of a metal material. Thus, the housing 120 functions as a heat sink that efficiently dissipates the heat generated from the semiconductor light emitting module 140 and the circuit unit 123 to the outside of the light bulb shaped lamp 100.

As a specific example of the metal material which constitutes case 120, for example, Al, Ag, Au, Ni, Rh, Pd, an alloy of two or more of them, an alloy of Cu and Ag, etc. can be considered. . Since such a metal material has good thermal conductivity, the heat transmitted to the housing 120 can be efficiently transmitted to the base 130 side. Therefore, the heat generated from the semiconductor light emitting module 140 and the circuit unit 123 can be dissipated to the lighting apparatus side through the base 130.

The housing 120 according to the present embodiment is made of an aluminum alloy material. Further, in order to improve the thermal emissivity of the housing 120, the surface of the housing 120 may be subjected to an alumite treatment. The material of the housing 120 is not limited to metal, and may be resin. For example, the housing 120 can be made of a resin or the like having a high thermal conductivity.

(Base 121)
The base 121 has, for example, a substantially annular shape having a through hole penetrating in the thickness direction at the central portion, and in the present embodiment, the cylinder axis thereof coincides with (parallel to) the lamp axis J (axial center of the base 130) ) To be arranged. The upper surface of the base 121 is a plane orthogonal to the lamp axis J, and is a mounting surface of the semiconductor light emitting module 140.

The “cylindrical axis” refers to an axis passing through the center of the base 121 and orthogonal to the mounting surface, and generally coincides with the main emission direction of the semiconductor light emitting element 142. However, the cylinder axis of the base 121 does not necessarily have to be parallel to the lamp axis J, and may be inclined in a predetermined direction with respect to the lamp axis J. That is, the cylinder axis can be set to an arbitrary direction in which the light output from the semiconductor light emitting element 142 is desired to be irradiated.

The base 121 is made of, for example, a metal material having high thermal conductivity. As a specific example of the metal material, for example, Al, Ag, Au, Ni, Rh, Pd, an alloy of two or more of them, an alloy of Cu and Ag, and the like can be considered. Thus, the heat generated in the semiconductor light emitting module 140 can be efficiently conducted to the housing 120.

As an example, the base 121 can be a substantially disk-shaped metal substrate molded by aluminum die casting. Thus, the base 121 can be functioned as a heat dissipation body for conducting the heat generated from the semiconductor light emitting module 140 to the casing 120 by forming the base 121 with a metal material.

In addition, as a method of fixing the semiconductor light emitting module 140 to the upper surface of the base 121, for example, screwing, bonding, or engagement can be considered. Further, the base 121 is not limited to a substantially annular shape, and may have any shape. Moreover, the upper surface of the base 121 does not necessarily have to be a plane as a whole as long as the semiconductor light emitting module 140 can be disposed in a plane. Furthermore, the lamp axis J and the mounting surface do not necessarily have to be orthogonal to each other, and it is sufficient that they intersect at a predetermined angle.

(Circuit holder 122)
The circuit holder 122 is composed of a substantially cylindrical main body portion 122 a having one end opened, and a connecting portion 122 b having a screw groove formed on the outer peripheral surface. Then, the open end of the main body portion 122 a of the circuit holder 122 is connected to the cap member 125, and the connection portion 122 b is connected to the base 130. Although the material which comprises the circuit holder 122 is not specifically limited, For example, what is necessary is just to form with insulating materials, such as resin.

Although the base 121 is positioned on the globe 110 side of the circuit holder 122, the circuit holder 122 and the base 121 are not in direct contact with each other, and a gap is provided between them. Further, the outer wall surface of the circuit holder 122 and the inner wall surface of the housing 120 are not in direct contact with each other, and a gap is provided between the two.

As described above, by providing a gap between the circuit holder 122 and the base 121 (or the housing 120), the heat generated in the semiconductor light emitting module 140 is transmitted to the circuit holder 122 via the base 121 and the housing 120. Propagation can be suppressed. Thereby, since the temperature rise of the circuit holder 122 can be suppressed, it can prevent that the circuit unit 123 is thermally destroyed.

(Circuit unit 123)
The circuit unit 123 is for lighting the semiconductor light emitting element 142, and is configured of various electronic components (not shown) mounted on the circuit board 124. The circuit unit 123 is housed in the circuit holder 122 and the cap member 125. As a method of fixing the circuit unit 123 to the circuit holder 122 and the cap member 125, for example, screwing, bonding, engagement and the like can be considered.

The circuit board 124 is disposed such that its main surface is parallel to the lamp axis J. In this way, the circuit unit 123 can be stored more compactly in the circuit holder 122. Then, among the electronic components constituting the circuit unit 123, the electronic component that is relatively weak to heat is disposed on the lower side of the circuit board 124 far from the semiconductor light emitting module 140. On the other hand, the relatively heat-resistant electronic component is disposed on the upper side of the circuit board 124 near the semiconductor light emitting module 140. Thereby, the heat generated in the semiconductor light emitting module 140 can effectively prevent the electronic component from being thermally destroyed.

(Cap member 125)
The cap member 125 has a hollow, generally frusto-conical shape, and the open large end is connected to the circuit holder 122. In addition, the cap member 125 holds the sensor 150 on the outer wall surface of the end on the small diameter side. The cap member 125 can be formed of, for example, the same material as the circuit holder 122.

(Cap 130)
The base 130 is a power receiving unit for receiving AC power by two contacts, and is mounted on a socket (not shown) of the lighting apparatus. The base 130 according to the present embodiment conforms to the standard of the E17 base defined in JIS (Japanese Industrial Standard), but the present invention is not limited to this. That is, the base 130 may be configured to conform to another standard (E26 base or the like) defined in JIS so as to be attached to a socket of another lighting fixture.

The base 130 includes a cylindrical shell 131 having a thread groove formed on the outer peripheral surface and the inner peripheral surface, and an eyelet 132 attached to the tip of the shell 131. The screw groove on the outer peripheral surface of the shell 131 is screwed into the socket of the lighting apparatus. Thereby, the light bulb shaped lamp 100 is fixed to the lighting fixture. Further, the screw groove on the inner peripheral surface of the shell 131 is screwed into the screw groove of the connecting portion 122 b of the circuit holder 122. Thereby, the circuit holder 122 and the base 130 are fixed.

Further, the circuit unit 123 and the base 130 are electrically connected by the stranded wire 160 including the first and

second feeders

161 and 162. More specifically, the first feeder line 161 electrically connects the circuit unit 123 and the shell 131. The second feeder line 162 electrically connects the circuit unit 123 and the eyelet 132.

Next, with reference to FIG. 3, how to attach the housing 120, the circuit holder 122, and the base 130 will be described in detail. First, the stopper ring 171 is fitted into the connection portion 122b of the circuit holder 122 and fixed by an adhesive or the like. Next, the connecting portion 122 b into which the stopper ring 171 is fitted is inserted into the opening of the proximal end portion 120 b of the housing 120. Further, the washer 172 and the insulating ring 173 are fitted in this order in the connecting portion 122b inserted into the opening of the proximal end portion 120b. Then, the connecting portion 122 b in this state is screwed into a screw groove formed on the inner peripheral surface of the eyelet 132 of the mouthpiece 130 and fixed.

That is, the circuit holder 122 and the base 130 always rotate integrally. On the other hand, since the housing 120 is sandwiched by the stopper ring 171 and the washer 172, the housing 120 normally rotates integrally with the circuit holder 122 and the cap 130. However, when a force larger than the frictional force between the housing 120 and the stopper ring 171 and the washer 172 is applied between the housing 120 and the base 130, the housing 120 and the base 130 rotate relative to each other.

Here, a stopper 171 a protruding toward the housing 120 is formed on the surface of the stopper ring 171 facing the housing 120. Further, on the inner peripheral surface that constitutes the opening of the proximal end portion 120b of the housing 120, an engaging portion 120c that protrudes toward the center of the opening is formed. Then, when the housing 120, the circuit holder 122, and the base 130 are relatively rotated, the stopper 171a and the engaging portion 120c are engaged to restrict further rotation. That is, the stopper 171 a and the engaging portion 120 c function as a restricting member that restricts relative rotation between the housing 120 and the circuit holder 122 and the cap 130.

(Semiconductor light emitting module 140)
FIG. 4 is a plan view showing the semiconductor light emitting module 140 according to the first embodiment. The semiconductor light emitting module 140 shown in FIG. 4 is provided on the mounting substrate 141 so as to cover the mounting substrate 141, a plurality of semiconductor light emitting devices 142 as light sources mounted on the mounting substrate 141, and the semiconductor light emitting devices 142. And the sealed body 143.

The semiconductor light emitting device 142 according to the present embodiment is a light emitting diode (LED). That is, the semiconductor light emitting module 140 is an LED module. However, for example, a semiconductor laser may be used as the semiconductor light emitting device 142. In addition, instead of the semiconductor light emitting element 142, a light emitting element such as an organic EL element or an inorganic EL element may be used.

The mounting substrate 141 has a substantially annular shape having a substantially circular hole at the center, and the semiconductor light emitting element 142 is mounted on one surface (upper surface in FIG. 2). Although the material which comprises the mounted substrate 141 is not specifically limited, For example, the ceramic substrate which consists of alumina etc. can be used.

Further, at one portion of the inner peripheral edge of the mounting substrate 141, a tongue piece portion 144 extending toward the center of the hole portion is formed. The tongue piece 144 is provided with a connector 146 to which the wire 145 of the circuit unit 123 is connected. Then, as shown in FIG. 2, the semiconductor light emitting module 140 and the circuit unit 123 are electrically connected by connecting the wiring 145 to the connector 146. Then, when the DC power is supplied from the circuit unit 123 through the wiring 145, the semiconductor light emitting element 142 emits light.

The semiconductor light emitting elements 142 are sealed, for example, in pairs as a pair by a substantially rectangular parallelepiped sealing body 143. Then, in the example of FIG. 4, 16 sets of sealing bodies 143 (that is, 32 semiconductor light emitting elements 142) are annularly arranged on the surface of the mounting substrate 141 so as to be point symmetrical with respect to the lamp axis J It is done. In other words, the longitudinal direction of each sealing body 143 coincides with the radial direction of the mounting substrate 141, and is arranged radially about the lamp axis J. The number of semiconductor light emitting elements 142 is not limited to a plurality, and may be one. Further, the arrangement of the semiconductor light emitting devices 142 is not limited to an annular shape, and may be, for example, a matrix.

The sealing body 143 is mainly made of a translucent material. Further, when it is necessary to convert the wavelength of light emitted from the semiconductor light emitting element 142 into a predetermined wavelength, a wavelength conversion material for converting the wavelength of light is mixed into the translucent material. As a translucent material, silicone resin can be utilized, for example. Moreover, as a wavelength conversion material, fluorescent substance particle can be utilized, for example.

In the present embodiment, a semiconductor light emitting element 142 for emitting blue light and a sealing body 143 formed of a translucent material mixed with phosphor particles for wavelength converting blue light to yellow light are employed. . That is, part of the blue light emitted from the semiconductor light emitting element 142 is wavelength-converted to yellow light by the sealing body 143, and white light generated by mixing the unconverted blue light and the converted yellow light is semiconductor The light is emitted from the light emitting module 140.

Furthermore, the semiconductor light emitting module 140 may be, for example, a combination of a semiconductor light emitting element emitting ultraviolet light and each color phosphor particle emitting light in three primary colors (red, green, blue). Furthermore, as the wavelength conversion material, a material including a semiconductor, a metal complex, an organic dye, a pigment, or the like, which absorbs light of a certain wavelength and emits light of a wavelength different from the absorbed light may be used. The semiconductor light emitting element 142 is disposed with its main emission direction directed upward along the lamp axis J direction.

(Sensor 150)
The sensor 150 is typically a so-called human sensor that detects the presence or absence of a person in the vicinity (within the illumination range) of the light bulb shaped lamp 100. As illustrated in FIG. 2, the sensor 150 includes a detection element 151, a lens 152, a control circuit 153, and a mounting substrate 154. The sensor 150 according to the present embodiment is held by the small diameter end of the cap member 125 so as to be located on the lamp axis J.

The detection element 151 is an element that detects a detection target (in this example, a person), and detects far infrared rays emitted by a human body. The lens 152 has a translucent hemispherical shape, and is disposed to cover the detection element 151. The lens 152 condenses outside light (in this example, far infrared rays emitted from the outside toward the sensor 150) on the detection element 151. That is, the lens 152 determines the detection range (detection angle) of the sensor 150.

The control circuit 153 is connected to the circuit unit 123 by the wiring 155, and notifies the circuit unit 123 of the detection result of the detection element 151 through the wiring 155. The mounting substrate 154 holds the detection element 151 and the control circuit 153. Specifically, the mounting substrate 154 holds the detection element 151 on one main surface and the control circuit 153 on the other main surface, and the detection element 151 and the control circuit 153 through a through hole (not shown). It may be electrically connected. Then, the mounting substrate 154 is fitted in the opening of the lens 152 with the detection element 151 directed toward the lens 152.

The light bulb shaped lamp 100 provided with the sensor 150 configured as described above operates, for example, as follows.

First, when the bulb-shaped lamp 100 is turned off, when a person enters the detection range of the sensor 150, the detection element 151 detects far-infrared rays emitted from the person. Next, the control circuit 153 notifies the circuit unit 123 that the detection element 151 has detected far-infrared radiation (ie, a person). The circuit unit 123 that has received the notification from the control circuit 153 supplies power to the semiconductor light emitting module 140. Thereby, the semiconductor light emitting element 142 emits light (the bulb-shaped lamp 100 is turned on).

On the other hand, when the light bulb-shaped lamp 100 is lit, the circuit unit 123 stops the supply of power to the semiconductor light emitting module 140 if the state in which the detecting element 151 does not detect far infrared rays continues for a predetermined time. Thereby, the light bulb shaped lamp 100 is turned off.

As described above, by turning on only when a person is detected and turning off when there is no person, it is possible to obtain a light bulb shaped lamp 100 capable of reducing power consumption while preventing forgetting to turn off. Further, since the sensor 150 is mounted on the light bulb shaped lamp 100 itself instead of the lighting fixture, lighting control by the human sensor can be easily realized even with the existing (without sensor) lighting fixture.

Further, since the light bulb-shaped lamp 100 employs an LED having a very long life as a light emitting element, even if the sensor 150 is mounted on the light bulb-shaped lamp 100 itself, it does not lead to a significant cost increase.

Here, it is desirable that the detection range of the sensor 150 can be adaptively changed according to the use environment of the light bulb shaped lamp 100 (that is, the place where the light bulb shaped lamp 100 is installed). Specifically, it is desirable to be able to selectively widen or selectively narrow the detection range in a predetermined direction.

Therefore, in the light bulb shaped lamp 100 according to the present embodiment, the sensor 150 is installed at an angle with respect to the lamp axis J. That is, the sensor 150 is installed on the bulb-shaped lamp 100 so that the mounting substrate 154 is not orthogonal to the lamp axis J. FIG. 5 is a view showing an example of a detection range of the sensor 150 mounted on the light bulb shaped lamp 100 according to the present embodiment.

As shown in FIG. 5, a sensor 150 is attached to the light bulb shaped lamp 100 according to the present embodiment so that the detection range is asymmetrical with respect to the lamp axis J. Specifically, the detection range on the side where the sensor 150 is inclined is widened, and the detection range on the opposite side is narrowed.

Then, as described with reference to FIG. 3, in the light bulb shaped lamp 100 according to the present embodiment, the globe 110, the housing 120, and the sensor 150 rotate integrally, and the housing 120 and the cap 130 are relative to each other. Rotate. That is, the orientation of the sensor 150 can be changed by rotating the housing 120 with respect to the base 130 in a state where the bulb-shaped lamp 100 is attached to the lighting fixture, so the detection range in a desired direction can be broadened or It is possible to narrow the detection range in the desired direction.

However, the method of making the detection range of the sensor 150 asymmetric with respect to the lamp axis J is not limited to the example of FIG. 6 and 7 are diagrams showing examples of detection ranges of the

sensors

250 and 350 mounted on the light bulb shaped

lamp

200 and 300 according to a modification of the present embodiment.

In the first modification shown in FIG. 6, the detection range of the sensor 250 is asymmetric with respect to the lamp axis J by making the focusing range (focus angle) of the lens 252 of the sensor 250 asymmetric with respect to the lamp axis J. I have to. This can be realized, for example, by designing the lens 252 so that the light distribution is asymmetric with respect to the lamp axis J. Alternatively, it can also be realized by shielding the side (the right side in the example of FIG. 6) on which the focusing range of the lens 252 is desired to be narrowed with a seal or the like.

Also in the first modification, it is possible to widen the detection range of the desired direction or narrow the detection range of the desired direction by rotating the casing 220 with respect to the base 230. In the first modification shown in FIG. 6, unlike the example of FIG. 5, it is not necessary to incline the sensor 250 with respect to the lamp axis J.

Further, while the

sensors

150 and 250 are disposed on the lamp axis J in the above example, the sensor 350 is disposed at a position deviated from the lamp axis J in the second modification shown in FIG. .

housings

120, 220, 320 and the

caps

130, 230, 330 may be integrally rotated, and the

gloves

110, 210, 310 and the

housings

120, 220, 320 may be relatively rotated. That is, any configuration may be used as long as any part of the lamp body rotates with respect to the base.

Furthermore, in each of the above examples,

passive sensors

150, 250, 350 for detecting far-infrared rays are described, but the present invention is not limited thereto. For example, the sensor may be an active sensor that detects an object to be detected (typically, a person) by outputting an electromagnetic wave and detecting its reflected wave.
