Abstract
The utility model discloses an all -round test fixture of LED filament, including total mark ball pillar, still include casing, positive electrode, negative electrode, circuit board, first dead lever, second dead lever, compare with prior art, this SMD LED's total mark ball sectional fixture simple structure, design benefit only needs to wait to detect the filament and places at first dead lever and second dead lever top, can accomplish the filament detection to detect the filament through the total mark ball, thereby guaranteed the detection precision of filament.
Description
Technical field
The utility model relates to a kind of sectional fixture, particularly relates to the comprehensive test fixture of a kind of LED silk.
Background technology
LED silk is a kind of brand-new LED form, by fixing for multiple chip-in series on the glass substrate, then carry out overmold and complete.LED light source will reach the illuminating effect of expection in the past, needed to carry out secondary optical design, then can reduce the light efficiency of LED light source own.LED silk has high-color rendering, specular removal, 360 ° of advantages such as omnibearing luminous, does not need secondary optical design, realizes three-dimensional light source, bring unprecedented lighting experience, be therefore applied to the LED illumination products such as crystal pendant lamp, candle lamp, bulb lamp.But LED silk brings new challenge to testing: it is 360 ° of light-emitting 3 D light sources, then require when integrating sphere is measured, dependence test fixture can not block its light, otherwise will affect optical measurements, therefore require test fixture must volume gently little and accuracy of measurement is high.The current LED silk without specialty is at integrating sphere measurement fixture, and the test fixture of routine cannot ensure its optical measurement accuracy, in view of above defect, is necessary to design the comprehensive test fixture of a kind of LED silk in fact.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of LED silk comprehensive test fixture, solves current filament detection difficulty large, the problem that accuracy is low.
For solving the problems of the technologies described above, the technical solution of the utility model is: the comprehensive test fixture of a kind of LED silk, comprise integrating sphere pillar, housing, positive electrode, negative electrode, wiring board, first fixed lever, second fixed lever, described housing is positioned at integrating sphere post top portion, described positive electrode is positioned on the right side of housing bottom, described positive electrode is connected with housing close-fitting, described negative electrode is positioned on the left of housing bottom, described negative electrode is connected with housing close-fitting, described wiring board is positioned at enclosure interior top, described wiring board is connected with housing screw thread, the first described fixed lever is connected with housing close-fitting, and the first described fixed lever is connected with wiring board printed line road, the second described fixed lever is positioned at case top central right, the second described fixed lever is connected with housing close-fitting.
Further, the first described fixed lever top is also provided with the first location notch, and the first described location notch is square groove.
Further, the second described fixed lever top is also provided with the second location notch, and the second described location notch is square groove.
Compared with prior art, the comprehensive test fixture of this LED silk, first positive electrode and negative electrode are inserted in integrating sphere pillar, electric current in integrating sphere pillar is sent on wiring board by positive electrode and negative electrode, filament to be detected is placed on the first fixed lever and the second fixed lever top, because the first fixed lever and the second fixed lever adopt copper cash to make, thus there is good conductivity, therefore positive electrode is reached, filament and negative electrode composition closed circuit, thus reach filament energising and luminous, therefore can complete filament to detect, this clamp structure is simple, design ingenious, only filament to be detected need be placed on the first fixed lever and the second fixed lever top, filament can be completed detect, and be detect filament by integrating sphere, thus ensure that the accuracy of detection of filament.

Embodiment
Hereinafter, set forth multiple specific detail, to provide the thorough understanding to the concept forming described embodiment basis.But to one skilled in the art, embodiment described obviously can be put into practice when not have in these specific detail some or all.In other cases, well-known treatment step is not specifically described.
As Fig. 1, shown in Fig. 2, comprise integrating sphere pillar 1, housing 2, positive electrode 3, negative electrode 4, wiring board 5, first fixed lever 7, second fixed lever 8, first location notch 701, second location notch 702, described housing 2 is positioned at integrating sphere pillar 1 top, described positive electrode 3 is positioned at right side bottom housing 2, described positive electrode 3 is connected with housing 2 close-fitting, described negative electrode 4 is positioned at housing 2 bottom left, described negative electrode 4 is connected with housing 2 close-fitting, described wiring board 5 is positioned at housing 2 inner tip, described wiring board 5 is connected with housing 2 screw thread, the first described fixed lever 7 is positioned on the left of housing 2 top center, the first described fixed lever 7 is connected with housing 2 close-fitting, and the first described fixed lever 7 is connected with wiring board 5 printed line road, the second described fixed lever 8 is positioned on the right side of housing 2 top center, the second described fixed lever 8 is connected with housing 2 close-fitting, described housing 2 surrounding is also provided with louvre 201, described louvre 201 quantity is several, the first described fixed lever 7 top is also provided with the first location notch 701, the first described location notch 701 is square groove, the second described fixed lever 8 top is also provided with the second location notch 801, the second described location notch 801 is square groove, the integrating sphere sectional fixture of this adopting surface mounted LED, first positive electrode 3 and negative electrode 4 are inserted in integrating sphere pillar 1, electric current in integrating sphere pillar 1 is sent on wiring board 5 by positive electrode 3 and negative electrode 4, convey electrical current in the first fixed lever 7 by wiring board 5 again, filament to be detected is placed on the first fixed lever 7 and the second fixed lever 8 top, because the first fixed lever 7 and the second fixed lever 8 adopt copper cash to make, thus there is good conductivity, make positive electrode 3, filament and negative electrode 4 form closed circuit, thus reach filament energising and luminous, therefore can complete filament to detect, its middle shell 2 is positive electrodes 3, negative electrode 4, wiring board 5, the installation carrier of the first fixed lever 7 and the second fixed lever 8, positive electrode 3 is longer than negative electrode 4, and both positive and negative polarity symbol is put in positive electrode 3 and negative electrode 4 outer end, thus prevent positive electrode 3 and negative electrode 4 from obscuring, due to a large amount of heats can be produced while filament electrified light emitting, first location notch 701 and the second location notch 801 can play positioning action to filament, prevent filament landing.
The utility model is not limited to above-mentioned concrete execution mode, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion made, all drop within protection range of the present utility model.
