Problems solved by technology

[0002] The LED light bar test is generally manually plugged in and then visually observed the LED lights on and off, bright and dark, color shift and other issues, the detection speed is slow and the resolution is poor, and the bright LED lights are harmful to human eyes. Large, for the automatic test method, the industry generally adopts the mechanical one-by-one test method. Although the precision is high, the test speed is slower than the manual test, and it cannot be used for production test on the industrial site

Embodiment 1

[0034] Embodiment one: if figure 1 As shown, the side-emitting LED light bar test device includes a light bar 1, a light bar carrier 6, a light bar power module 7, a light bar test board 2, a digital camera 8, and a calculation control unit 9. The light bar 1 has A plurality of LED lights 5, the light bar 1 is multiple, the light bar 1 is fixed on the light bar carrier 6, the light bar power module 7 indirectly supplies power to the light bar 1 through the light bar test board 2, the light bar The pin 4 of the light bar board 1 is connected to the light bar test board 2, the power terminal of the light bar test board 2 is connected to the light bar power module 7, and the control terminal of the light bar power module 7 is connected to the computing control unit 9. Specific implementation methods, such as figure 1 As shown, a PIN pin 3 is fixed on the light bar test board 2 , one end of the PIN pin 3 is tied to the pin 4 of the light bar board of the light bar 1 , and the ot...

Embodiment 2

[0040] like Figure 5 As shown, the difference from Embodiment 1 is that the light guiding device is a second light guiding column 18, and the second light guiding column 18 includes an upper end and a lower end, the upper end is a square, and the lower end It is a wedge-shaped block whose transverse longitudinal section is an equilateral triangle. The vertical surface of the wedge-shaped block is the light-incident surface, and the slope forming an angle of 40-65 degrees with the vertical light-incident surface is the reflective surface. The upper surface of the square It is the light exit surface, and the light incident surface and the reflective surface form a certain included angle, and the included angle is 40-65 degrees. The light incident surface, reflecting surface and light emitting surface are respectively located on the reflected light path of the LED lamp 5 . The second light guide column 18 is fixed on the light strip test board 2, and is located near the light o...

Embodiment 3

[0043] The difference from the second embodiment is that a light-transmitting column is fixed at the second light-transmitting hole 16 , and the upper surface of the light-transmitting column is an atomized surface 12 . It is also possible to paste a layer of atomized film 15 on the upper surface of the light-transmitting column.

Abstract

The invention relates to a testing device for LED light strips with side luminance. The testing device comprises the light strips, a light strip carrier, a light strip power module, a light strip testing board, a digital camera and a computing control unit. The light strips are provided with a plurality of LED lights and fixed on the light strip carrier. A plurality of light strips are arranged. The light strip power module supplies power to the LED light strips. The light strip testing board is provided with a light-transmitting device and located above the light strip carrier through a locating device. The digital camera is fixed on the portion above the light strip testing board. The light of the LED lights on the light strips illuminates the digital camera through the light strip testing board. The digital camera is connected with the computing control unit. According to the method, ten to sixty light strips can be tested at the same time, and the speed is increased by 10 times-60 times compared with that of manual work; moreover, uncertainty influence of human factors is avoided, the testing specification takes the numerical value as the standard, the stability and precision are ensured, and the online testing requirement of the LED light strips can be met completely; the cost is saved, the efficiency is improved, and the quality is ensured.

Description

technical field [0001] The invention relates to a testing device and method for a side-emitting LED light bar. Background technique [0002] The LED light bar test is generally manually plugged in and then visually observed the LED lights on and off, bright and dark, color shift and other issues, the detection speed is slow and the resolution is poor, and the bright LED lights are harmful to human eyes. Large, for the automatic testing method, the industry generally adopts the mechanical one-by-one testing method. Although the accuracy is high, the testing speed is slower than manual testing, and cannot be used for production testing on the industrial site. Contents of the invention [0003] In order to solve the above problems, the present invention provides a testing device and method for side-emitting LED light strips. It has no uncertain influence of human factors, ensures stability and accuracy, and can fully meet the online testing requirements of LED light strips. I...
