DETAILED DESCRIPTION

[0021] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] A light bar lighting test device, such as Figure 1 and Figure 2 As shown, it includes a base 1 and a power source for lighting the light bar. The base 1 is provided with a carrier placement area, a short-circuit area and a test area. The short-circuit area and the test area are both located above the carrier placement area. The carrier placement area is provided with a carrier 2, and the first group of light bars 15 and the second group of light bars 16 are installed on the carrier 2. The short-circuit area includes a short-circuit board 3 and a No. 1 probe bar 4 and a No. 2 probe bar 5 installed on the short-circuit board 3. The lower end surfaces of the No. 1 probe bar 4 and the No. 2 probe bar 5 are both installed with probes 6. The probes 6 of the No. 1 probe bar 4 correspond to the positions of the conductive sheets of the first group of light bars 15, and the probes 6 of the No. 2 probe bar 5 correspond to the positions of the conductive sheets of the second group of light bars 16. The upper end surfaces of the No. 1 probe bar 4 and the No. 2 probe bar 5 are both installed with wires 7. The wires 7 short-circuit the corresponding probes 6 on the No. 1 probe bar 4 and the No. 2 probe bar 5. The test area is installed with a light bar test board, which covers the light-emitting part of the light bar on the carrier 2 . The light bar test board and the short-circuit board 3 are both hinged on the base 1 .

[0023] Before the test, open the light bar test board and the short-circuit board 3, place the carrier 2 with the first group of light bars 15 and the second group of light bars 16 installed in the carrier placement area, then put down the light bar test board and the short-circuit board 3, the probe 6 on the No. 1 probe bar 4 contacts the conductive sheet of the first group of light bars 15, and the probe 6 on the No. 2 probe bar 5 contacts the conductive sheet of the second group of light bars 16, and the corresponding probes 6 on the No. 1 probe bar 4 and the No. 2 probe bar 5 are short-circuited through the wire 7, thereby realizing the short-circuit of the first group of light bars 15 and the second group of light bars 16. There is no need to install a complicated short-circuit connector, the operation is simple, the detection efficiency is high, and it is convenient for lighting tests of multiple light bars. After the short-circuit of the first group of light bars 15 and the second group of light bars 16 is completed, turn on the power supply, and multiple light bars on the two groups of light bars can be lit at the same time. After the light bars are lit, observe the light effect of the light bars through the light bar test board to evaluate whether they are qualified.

[0024] like Figure 1 As shown, the power supply includes a DC power supply 10, a test line 11 and a power connector 12. The power connector 12 is installed on the first group of light bars 15, and the power connector 12 is connected to the DC power supply 10 through the test line 11. Since the first group of light bars 15 and the second group of light bars 16 are short-circuited, turning on the DC power supply 10 can light up the two groups of light bars at the same time.

[0025] like Figure 1 and Figure 2 As shown, the probe 6 is a retractable probe 6, which can make good contact with the conductive sheet of the light bar without causing damage such as bending to the conductive sheet.

[0026] like Figure 1As shown, the light bar test board includes a diffuser plate 8 and a glass plate 9. The diffuser plate 8 is installed on the lower surface of the glass plate 9, and the glass plate 9 is hinged to the base 1. The diffuser plate 8 is used to refract the light emitted by the first group of light bars 15 and the second group of light bars 16 after lighting, and whether the light bar is qualified is judged according to whether the light effect is good or not; because the diffuser plate 8 is soft, the diffuser plate 8 and the glass plate 9 are installed in combination as the light bar test board, which can prevent the diffuser plate 8 from bending and affecting the light effect and test results of the light bar.

[0027] like Figure 1 As shown, a limiting block 14 is provided on the peripheral side of the carrier 2 to limit and fix the carrier 2.

[0028] In this embodiment, the short-connect plate 3 is a glass short-connect plate 3 , and the glass short-connect plate 3 and the glass plate 9 are both hinged to the base 1 through hinges 13 .

[0029] In this embodiment, short-circuiting refers to connecting the positive conductive sheet of the first group of light bars 15 with the negative conductive sheet of the second group of light bars 16 through the wire 7, and connecting the negative conductive sheet of the first group of light bars 15 with the positive conductive sheet of the second group of light bars 16. The number of probes 6 is the same as the sum of the number of conductive sheets included in the first group of light bars 15 and the second group of light bars 16, and is twice the number of wires 7. In actual operation, the number of groups of light bars, the number of light bars in each group, and the number of probes can be changed according to needs.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
