Embodiment
Below in conjunction with embodiment the present invention is done further detailed description.
Embodiment 1, and Fig. 1 is embodiments of the invention 1 structural representations.Visible by figure; Electricity-saving lamp fluorescent powder thickness of the present invention and uniformity measurement device; Be made up of computing machine 1, multi-functional data card 2, prime amplifier 3, measuring light detector 4, reference light detector 11, turntable 9, turntable driver 6, LASER Light Source 7, semi-permeable and semi-reflecting mirror 8, catoptron 10, fluorescent tube to be measured 5, the position of above-mentioned component concerns as follows:
Described computing machine 1 links to each other with multi-functional data card 2, and links to each other with described prime amplifier 3, turntable driver 6, LASER Light Source 7 respectively through multi-functional data card 2; Fluorescent tube 5 to be measured, is rotated with turntable on the rotating part of described turntable 9 by clamping; Described catoptron 10 and measuring light detector 4 all are fixed in the fixed part of turntable 9; 8 one-tenth 45 ° of angles of light beam that described LASER Light Source 7 sends and semi-permeable and semi-reflecting mirror; Reference light detector 11 is positioned at the transmission direction of this semi-transparent semi-reflecting lens 8, is used to survey the reference light intensity of transmission; Described catoptron 10 is positioned within the reflected light direction and fluorescent tube to be measured 5 of described semi-transparent semi-reflecting lens 8; Described measuring light detector 4 is positioned at the outside of fluorescent tube 5 to be measured; And be close to fluorescent tube, measured photo-detector 4 receives after described catoptron 10 laser light reflected see through the tube wall of fluorescent tube 5 to be measured; Described catoptron 10 all is fixed on the fixed part of universal stage 9 with measuring light detector 4; Do not rotate with turntable; Described measuring light detector 4 will convert electric signal into through tube wall light intensity to be measured with reference to light intensity respectively with reference light detector 11; Convert digital signal into through prime amplifier 3 amplifications, multi-functional data card 2AD afterwards, by described computing machine 1 analysis and processing.
Described catoptron 10 is fixed on the fixed part of revolving-turret 9 with photodetector 4, does not rotate with turntable 9; And fluorescent tube to be measured 5 by clamping on the rotating part of revolving-turret 9, can be with 9 360 ° of rotations of turntable.
LASER Light Source 7 is the red light semiconductor laser of 675nm wavelength; Be coated with reflectivity 80% on the semi-transparent semi-reflecting lens, the reflectance coating of transmitance 20%; Catoptron 10 is to be cut into 45 ° of angles of axis and to be coated with the reflective coating glass bar by an end face to process; There is perforate at the center of universal stage 9, after center drilling toward mirror 10, this catoptron 10 makes laser beam from fluorescent tube 5 inboard ejaculations to be measured to laser through semi-transparent semi-reflecting mirror reflection; Fluorescent tube 5 to be measured is the parts that cut down from power saving fluorescent lamps, and its length is by the radius-of-curvature decision of fluorescent tube, and the inwall that can not run into fluorescent tube 5 to be measured with the upper end of catoptron 10 is a cardinal rule.
The course of work of the present invention is as follows:
Measure one group of nominal data earlier.
With the polylith sheet glass of fluorescent tube consistency of thickness to be measured on evenly smear one deck different-thickness respectively fluorescent powder as standard specimen; Measure the fluorescent powder thickness of each piece standard specimen with Other Instruments (like the step appearance); And measure the transmisivity data of each standard specimen respectively with apparatus of the present invention; Obtain fluorescent powder thickness~transmission change curve with this, curve only need be measured the concrete thickness that transmissivity can be known fluorescent powder afterwards in view of the above.Need not to know concrete thickness if only need measure the distribution situation of fluorescent powder, then can omit this step, the transmissivity distribution of only measuring fluorescent tube gets final product.
Measure the transmissivity distribution of fluorescent tube.
The whole power saving fluorescent lamps that coats fluorescent powder to be tested cut into the segment of suitable length, and serial number, test piecemeal in order, test result is gathered, can obtain the distribution situation of fluorescent powder on the whole electricity-saving lamp.Process to the test of each segment fluorescent tube is following: with fluorescent tube 5 clampings to be measured on test board; Computing machine 1 is opened LASER Light Source 7; And control turntable 9 drives fluorescent tube 5 uniform rotation to be measured; Simultaneously through multi-functional data card 2 record measuring light detectors 4 and the light intensity signal that reference light detector 11 is received, so can obtain on this segment tube inner wall to be measured on a certain cross section distribution situation of fluorescent powder in 360 ° of scopes; Change the clip position of fluorescent tube to be measured, can obtain the relevant light intensity data in another cross section equally.The light intensity that to measure through fluorescent powder obtains transmissivity distribution and changes with reference to light intensity normalization, has so eliminated because the unstable influence that is brought of laser power can significantly improve measuring accuracy.
Embodiment 2, and Fig. 2 is embodiments of the invention 2 structural representations.What embodiment 2 and embodiment 1 were different is that measuring light detector 4 is fixed on the rotating part of revolving-turret 9 with catoptron 10, and fluorescent tube 5 to be measured keeps motionless in the test process.Its test philosophy and operating process and embodiment 1 are identical.With respect to embodiment 1, the revolving-turret of perforate in the middle of need not in the present embodiment, cost is lower, but in rotary course, still wants being connected of holding circuit and light path, has certain inconvenience.
Fig. 3 is the normalization thickness map in certain cross section of a kind of power saving fluorescent lamps of employing the present invention measurement.
The invention provides a kind of electricity-saving lamp fluorescent powder thickness and uniformity appearance; Successfully realized the inhomogeneity measurement of fluorescent powder, can measure fluorescent tube fluorescent powder homogeneity situation of change in 360 ° of scopes of different cross section comprehensively, had reasonable in design, simple in structure, plurality of advantages such as the used expense of realization is low, use operation facility simultaneously linear pattern, U type, screw type and other various special-shaped fluorescent tubes; Be particularly useful for electricity-saving lamp manufacturer; The data of measurement device are improved production technology in view of the above, make the distribution of fluorescent powder be tending towards theoretical optimal value; And then the luminescence efficiency of raising electricity-saving lamp, the purpose of realization energy-saving low-carbon environmental protection.
