[0040] Embodiment

[0041] This embodiment provides a lighting device for a light source module, specifically a fast lighting device for a light source module (hereinafter simply referred to as "lighting device") for lighting the light source module 400 (seeFigure 4 ) so that inspectors can inspect the light source module 400.

[0042] Please also read Figure 1 and Figure 2 The lighting device includes a fixture base 100, a needle mold 200 and a negative pressure mechanism 300.

[0043] The fixture base 100 has a carrying surface 110 for placing the light source module 400 .

[0044] Accordingly, the needle mold 200 is connected to the fixture base 100 and exposed on the bearing surface 110. The needle mold 200 includes a probe 210 (see Figure 3 ).

[0045] In addition, the negative pressure mechanism 300 includes a negative pressure suction cup 310. The negative pressure suction cup 310 is connected to the fixture base 100 and exposed on the bearing surface 110. The negative pressure suction cup 310 is used to absorb the light source module 400 so that the terminal 410 of the light source module 400 is in contact with the probe 210.

[0046] It is understandable that the negative pressure suction cup 310 is generally made of elastically deformable materials such as rubber to ensure that the negative pressure suction cup 310 can fit tightly with the surface of the object to be adsorbed to avoid air leakage. When the air in the negative pressure suction cup 310 is sucked away and is in a negative pressure state, the negative pressure suction cup 310 will shrink and deform to a certain extent, thereby driving the light source module 400 to move closer to the fixture base 100 until the terminal 410 and the probe 210 are in contact and conductive.

[0047] When using the above-mentioned lighting device, the inspector places the light source module 400 to be inspected on the bearing surface 110 of the fixture base 100, and aligns the terminal 410 of the light source module 400 with the needle mold 200. Subsequently, the negative pressure suction cup 310 in the negative pressure mechanism 300 adsorbs the light source module 400, so that the terminal 410 and the probe 210 in the needle mold 200 are stably contacted and connected, and then the light source module 400 is illuminated, so that the inspector can inspect the light source module 400. During the inspection process, the negative pressure suction cup 310 applies force to the back of the light source module 400 where the terminal 410 is located, and the light-emitting surface of the light source module 400 is not blocked, so the visual effect inspection can be carried out normally.

[0048] Furthermore, a plurality of negative pressure suction cups 310 are provided, and the plurality of negative pressure suction cups 310 are arranged around the needle mold 200 .

[0049] When in use, multiple negative pressure suction cups 310 simultaneously absorb the light source module 400, so that the area near the terminal 410 on the light source module 400 is evenly stressed, which helps to ensure that the terminal 410 is parallel to the probe 210, and further ensure that the terminal 410 is in contact and conductive with each probe 210.

[0050] Further, the negative pressure mechanism 300 further includes a gas storage type negative pressure pump, and a plurality of negative pressure suction cups 310 are all connected to the gas storage type negative pressure pump.

[0051] During use, the gas storage type negative pressure pump can improve the stability of the negative pressure suction cup 310 for adsorbing the light source module 400, avoid obvious fluctuations in the suction force exerted by the negative pressure suction cup 310 on the light source module 400, and ensure that the terminal 410 is always in contact conduction with the probe 210.

[0052] Please refer to Figure 3 and Figure 4 specifically, the needle die 200 further includes a probe seat 220 and a protection seat 230. The probe seat 220 is connected to the fixture base 100. The protection seat 230 is elastically connected to the probe seat 220 along the first direction X, and the protection seat 230 is exposed on the bearing surface 110.

[0053] In addition, the probe 210 is disposed through the probe seat 220 and the protection seat 230 along the first direction X and is in sliding fit with the protection seat 230.

[0054] Wherein, the first direction X is perpendicular to the bearing surface 110, and the probe 210 penetrates out of the protection seat 230 when the light source module 400 pushes against the protection seat 230 along the first direction X.

[0055] When not in use, the head of the probe 210 is recessed into the protection seat 230. The protection seat 230 protects the probe 210 to prevent the probe 210 from being knocked and damaged.

[0056] When the negative pressure suction cup 310 adsorbs the light source module 400 and makes the light source module 400 approach the fixture base 100, the light source module 400 pushes against the protection seat 230 along the first direction X, causing the protection seat 230 to move toward the probe seat 220 along the first direction X, and further causing the probe 210 to penetrate out of the protection seat 230. At this time, the head of the probe 210 is exposed and comes into contact conduction with the terminal 410 to light up the light source module 400.

[0057] After the detection is completed, the tester removes the light source module 400, and the protection seat 230 bounces up again to protect the probe 210 inside.

[0058] Please combine Figure 5 In this embodiment, the needle die 200 further includes a thimble assembly 240. The thimble assembly 240 is composed of a thimble seat 241, a thimble 242, and a first spring 243, and the protection seat 230 is elastically connected to the probe seat 220 along the first direction X through the thimble assembly 240.

[0059] The ejector seat 241 is connected to the probe seat 220. The ejector pin 242 is slidably disposed in the ejector seat 241 along the first direction X, and one end of the ejector pin 242 away from the probe seat 220 is inserted into the protection seat 230. The first spring 243 is located in the ejector seat 241 and elastically resists the ejector pin 242.

[0060] When the light source module 400 pushes against the protection seat 230 along the first direction X, the protection seat 230 overcomes the elastic force of the first spring 243 and drives the ejector pin 242 to move toward the probe seat 220. When the thrust applied by the light source module 400 to the protection seat 230 is removed, the first spring 243 again bounces the ejector pin 242 and the protection seat 230. In this process, the ejector pin 242 slides with the ejector seat 241 along the first direction X, so that the protection seat 230 can only move along the first direction X without being offset.

[0061] In another embodiment of the present application, a guide post is provided on the probe seat 220. The guide post is provided along the first direction X and is slidably provided on the probe seat 220, and one end of the guide post is connected to the protective seat 230. In addition, a second spring is sleeved on the guide post, and the second spring elastically supports the probe seat 220 and the protective seat 230 respectively.

[0062] When the light source module 400 pushes against the protection seat 230 along the first direction X, the protection seat 230 overcomes the elastic force of the second spring and moves toward the probe seat 220. When the thrust applied by the light source module 400 to the protection seat 230 is removed, the second spring bounces up the protection seat 230 again. In this process, the guide post slides with the probe seat 220 along the first direction X, so that the protection seat 230 can only move along the first direction X without being offset.

[0063] Furthermore, a positioning groove 231 is provided on a side of the protection base 230 away from the probe base 220 , and the positioning groove 231 is used for the terminal 410 to be embedded.

[0064] Correspondingly, when the light source module 400 pushes against the protection seat 230 along the first direction X, the probe 210 passes through the bottom of the positioning groove 231 .

[0065] When the inspector places the light source module 400 to be inspected on the bearing surface 110, the terminal 410 is embedded in the positioning groove 231, and the terminal 410 can be positioned to ensure that the terminal 410 is aligned with the needle mold 200. When the light source module 400 pushes against the protection seat 230 along the first direction X, and the protection seat 230 moves toward the probe seat 220 along the first direction X, the probe 210 passes through the bottom of the positioning groove 231 and contacts and conducts with the terminal 410.

[0066] It should be noted that the terminal 410 has an insulating housing and a metal conductive part, and the metal conductive part is recessed inward compared to the insulating housing. Understandably, the depth of the inward recess of the metal conductive part is the height at which the probe 210 finally penetrates through the protective seat 230, generally 0.5 mm.

[0067] In some embodiments, the needle die 200 further includes a probe adapter board 250. The probe adapter board 250 is connected to the fixture base 100, and both the probe seat 220 and the probe 210 are connected to the probe adapter board 250.

[0068] Among them, the probe adapter board 250 serves as the base of the entire needle die 200, and the probe seat 220 is connected to the fixture base 100 through the probe adapter board 250. At the same time, a circuit is arranged in the probe adapter board 250 and is electrically connected to the probe 210, playing a role of electrical connection transfer.

[0069] Furthermore, a plurality of support columns 251 are provided on the probe adapter board 250. The plurality of support columns 251 are all arranged along the first direction X, and one end of the support column 251 is connected to the probe adapter board 250, and the other end is connected to the probe seat 220.

[0070] When assembling the needle die 200, the flatness of the probe seat 220 can be adjusted by adjusting the height of the probe seat 220 on each support column 251, ensuring that the terminal 410 abuts against the probe 210 in parallel, and further ensuring that the terminal 410 is in contact conduction with each probe 210.

[0071] In summary, when using the above lighting device, the tester places the light source module 400 to be tested on the bearing surface 110 of the fixture base 100 and aligns the terminal 410 of the light source module 400 with the needle die 200. Subsequently, the negative pressure suction cup 310 in the negative pressure mechanism 300 adsorbs the light source module 400, enabling the terminal 410 to be stably in contact conduction with the probe 210 in the needle die 200, thereby lighting up the light source module 400 for the tester to detect the light source module 400. During the detection process, the negative pressure suction cup 310 applies force to the back of the light source module 400 where the terminal 410 is located, and the light emitting surface of the light source module 400 is unobstructed, so the visual effect detection can be carried out normally. In addition, the above lighting device is simple to operate and can be quickly mastered. It only takes 10 s for the tester to manually switch the light source module 400 to be tested. In contrast, when using the method of inserting a wire harness into the slot of the light source module 400 and passing current, it takes 1 minute to switch the light source module 400 to be tested, with low efficiency.

[0072] This embodiment also provides a detection device, including the above light source module 400 lighting device.

[0073] In all examples shown and described herein, any specific values should be construed as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments may have different values.

[0074] It should be noted that like reference numerals and letters denote like items in the following figures. Thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

[0075] The above-described embodiments merely represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed. However, it should not be construed as a limitation on the scope of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and all of these belong to the protection scope of the present utility model.
