Embodiment
Above-mentioned and other aspect of the present invention, feature and advantage will the detailed description of following various more specific exemplary embodiments and accompanying drawing with reference under easilier understand, identical components in the wherein identical Ref. No. ordinary representation exemplary embodiment of the present invention, and appended relevant indicators is not drawn according to practical structures or ratio, and its effect only is to express architectural feature of the present invention.Need be appreciated that in addition the present invention is not limited to the details of specific embodiment and describes.
The stereogram and the top view of the last lamp socket 30 that is used for bulb that provides according to one embodiment of the invention is provided respectively for Fig. 2 and Fig. 3.In the present embodiment, last lamp socket 30 includes substrate disk 32, be connected to the annular exterior wall 34 of substrate disk 32 and be arranged on interior wall 36 on the substrate disk, and wherein interior wall 36 is positioned within the annular exterior wall 34, and with the annular exterior wall 34 spacing d of being separated by.Annular exterior wall 34 comprises the through hole 38 that is used to dispel the heat, interior wall 36 is then corresponding to through hole 38, and be not less than the height of the through hole 38 of annular exterior wall 34, so can reach the effectiveness of obstruct, avoid extraneous foreign matter via through holes 38 and enter the inside of bulb, and then influencing the usefulness of bulb, the inner heat that produces of bulb still can utilize the mode of convection current to drain into the external world by through hole 38 simultaneously.
In the present embodiment, annular exterior wall 34 is arranged on the edge of substrate disk 32, and in order to increase radiating effect, annular exterior wall 34 has the through hole 38 of four finedraw shapes, and the width D of through hole 38 is 1 millimeter (mm), so diameter can't enter greater than the foreign matter more than 1 millimeter.In the present embodiment, interior wall 36 corresponds respectively to the through hole 38 of annular exterior wall 34 and is provided with, and having spacing d with annular exterior wall 34 is 1.5 millimeters, because the width D of the through hole 38 of annular exterior wall 34 is 1 millimeter, therefore diameter is the foreign matter below 1 millimeter, still may pass through through hole 38, yet it will be subjected to the obstruct of interior wall 36 and can't continue toward in to advance, and because the spacing d of interior wall 36 and annular exterior wall 34 only is 1.5 millimeters, so foreign matter is difficult to cross over interior wall 36 and touches circuit board (figure does not show).
Through hole 38 can have the design of different shape or size according to different demands, yet preferably can to have a width D be 0.8 millimeter～20 millimeters for it, and interior wall 36 can be preferably with the annular exterior wall 34 spacing d of being separated by be 0.5 millimeter～20 millimeters.
Although in the present embodiment, interior wall 36 is for corresponding respectively to each through hole 38, yet in other kinds example, interior wall 36 also can be a ring-shaped continuous structure, or can be simultaneously corresponding to a plurality of through holes 38, that is to say, the visual actual demand of design such as the shape of interior wall 36 and through hole 38, quantity and changing, the present invention is subject to this.
In the present embodiment, dividing wall 40 connects the outside and the annular exterior wall 34 of interior wall 36, abutment wall 42 is the end 44 and annular exterior wall 34 of connection interior wall 36 then, dividing wall 40 is contour with abutment wall 42 and interior wall 36, and dividing wall 40 and abutment wall 42 both all can be in order to increase the integrally-built intensity that goes up lamp socket 30.But those skilled in the art ought know that in other embodiments the quantity of dividing wall 40 also can design according to the actual requirements, and dividing wall 40 also can not need with interior wall 36 contour.In this embodiment, abutment wall 42 can stretch into two ends 44 of through hole 38 back pile warp interior walls 36 in order to avoid foreign matter, and then touches circuit board (figure does not show).
Supporting pillar 48 is arranged on the substrate disk 32 and with annular exterior wall 34 and is connected, and the height of supporting pillar 48 is between interior wall 36 and annular exterior wall 34, and more preferably between interior wall 36 and reference column 46, and supporting pillar 48 height each other equates, thus, then the circuit board behind the location will drop down onto on the supporting pillar 48.In the present embodiment, the quantity of supporting pillar 48 is three, and each supporting pillar 48 equidistantly is provided with on the substrate disk 32 each other, but those skilled in the art are when knowing in other embodiments, supporting pillar 48 also can be other quantity, and can be non-equidistantly being arranged on the substrate disk 32, as long as that is can support circuit board.
In addition, when the size of circuit board too hour, then reference column 46 and supporting pillar 48 also can optionally extend toward substrate disk 32 centers.
In the present embodiment, substrate disk 32 has three openings 50 with the increase radiating effect, but the present invention need not limit the shape and the quantity of opening 50, and it can be decided according to the actual requirements.The structure of the last lamp socket 30 that present embodiment provided can be one of the forming or via assembled, the present invention is not as limit.
Another embodiment of the present invention then provides a kind of discharge bulb, and it can comprise the last lamp socket 30 that cell-shell, fluorescent tube, circuit board, following lamp socket, conductive head and the foregoing description are provided.Because comprising, the last lamp socket 30 that the foregoing description provided can be used for interior wall 36 structures that blocking foreign body enters the inside of discharge bulb, therefore the size of the through hole 38 of annular exterior wall 34 can suitably be amplified again, and then makes the heat energy that inside produced of discharge bulb more effectively drain into the external world by through hole 38.In addition, because last lamp socket 30 has the structure of supporting pillar 48, so the circuit board in the discharge bulb can be comparatively fixing, and can enter through hole 38 places of the inside of discharge bulb further from extraneous foreign matter, avoids circuit board to be polluted.
In sum, it will be appreciated by those skilled in the art that the above embodiments only in order to describe the present invention, right the present invention is not limited to the description of above specific embodiment, of the present invention be intended to comprise all this type of revise and change, with can real spirit according to the invention and scope.
