[0030] In this embodiment, the clamping assembly 1 and the adjusting assembly 2 constitute a clamping device for LED lamp testing involved in this application, which realizes the operations of clamping the LED lamp during testing and adjusting it according to the size of the LED lamp.

[0031] In this embodiment, the core structure of the LED lamp is a PN junction, which is composed of a P-type semiconductor and an N-type semiconductor. When a forward voltage is applied across the PN junction, the built-in electric field is weakened, and electrons and holes move to the P region and N region respectively under the action of the electric field force. Minority carriers that enter the other region will recombine with the majority carriers. This recombination process will release energy, part of which is emitted in the form of photons, thereby generating luminescence.

[0032] In this embodiment, by starting the electric telescopic rod 12, the first connecting plate 13 is pulled, driving the rack 14 to move downward, and the rack 14 and the circular gear 15 are engaged, thereby driving the circular gear 15 to rotate.

[0033] It should be noted that, by driving the driving motor 22, the bidirectional threaded rod 23 is driven to rotate on the fixed shell 21, which can drive the two sets of threaded sleeves 25 to move in opposite directions, and can drive the fixed shell 11 to move in opposite directions.

[0034] Specifically, the lower end of the electric telescopic rod 12 is fixed to the inner side of the fixed shell 11, and the first connecting plate 13 is fixed to the end of the electric telescopic rod 12 away from the fixed shell 11, and the rack 14 is fixed to the side of the first connecting plate 13 away from the fixed shell 11, and the circular gear 15 is meshed with the rack 14, the circular gear 15 is arranged in the middle position of the bidirectional threaded rod 16, and the two ends of the circular gear 15 are rotatably connected to the fixed shell 11, and the threaded sleeve 17 is provided with two groups and symmetrically arranged on both sides of the circular gear 15, and the connecting rod 18 and the clamping plate 19 are respectively provided with two groups and symmetrically arranged for use. The LED lamp is clamped and fixed in opposite directions, and the clamping plate 19 is fixed to the end of the connecting rod 18 away from the threaded sleeve 17, and the LED lamp body 3 is attached to the side of the clamping plate 19 away from the connecting rod 18, and the LED lamp body 3 is arranged between the two groups of clamping plates 19, and the end of the threaded sleeve 17 away from the connecting rod 18 is fixed to the second connecting plate 110, and the side of the fixed shell 11 away from the clamping plate 19 is provided with a slide groove 111, and the slide groove 111 is arranged horizontally, and the end of the second connecting plate 110 away from the threaded sleeve 17 slides on the slide groove 111, and the clamping assembly 1 is provided with two groups.

[0035] As a preferred embodiment, the rotation of the circular gear 15 can drive the bidirectional threaded rod 16 to rotate on the fixed shell 11, driving the two sets of threaded sleeves 17 to move in opposite directions, so that the two sets of clamps 19 can clamp and fix the LED lamp body 3.

[0036] As a preferred embodiment, by rotating the bidirectional threaded rod 16, the threaded sleeve 17 can move in the opposite or reverse direction, so that the second connecting plate 110 can slide on the slide groove 111, and the slide groove 111 can limit the second connecting plate 110 and the threaded sleeve 17 to prevent the threaded sleeve 17 from rotating with the bidirectional threaded rod 16.

[0037] Specifically, the drive motor 22 is fixed to the inner side of the fixed shell 21, and the end of the bidirectional threaded rod 23 away from the drive motor 22 is rotatably connected to the fixed shell 21, and the threaded sleeve 25 is provided with two groups and is symmetrically arranged on the bidirectional threaded rod 23. The inner side of the fixed shell 21 is fixed with a limiting slide 24, and the limiting slide 24 is provided with two groups and is symmetrically arranged on both sides of the drive motor 22. At the same time, the threaded sleeve 25 is fixed to the lower end of the fixed shell 11.

[0038] As a preferred embodiment, the rotation of the bidirectional threaded rod 23 drives the two sets of threaded sleeves 25 to move in opposite or reverse directions, and slide in opposite or reverse directions on the two sets of limiting slides 24, and the threaded sleeves 25 are limited by the two sets of limiting slides 24.

[0039] It should be noted that, by the two sets of threaded sleeves 25 moving in opposite directions or in opposite directions, the two sets of clamping components 1 can be driven to move in opposite directions or in opposite directions, so as to be adjusted according to the size of the LED lamp body 3 .

[0040] When in use, by starting the electric telescopic rod and pulling the first connecting plate, the rack is driven to move downward, and the circular gear drives the two-way threaded rod to rotate, which can drive the two sets of threaded sleeves to move in one direction, and the LED lamp body can be clamped in opposite directions through the two sets of clamping plates. By starting the driving motor and driving the two-way threaded rod to rotate, the two sets of threaded sleeves can be driven to slide on the limiting slide rod, and the two sets of clamping components can be driven to move in opposite or reverse directions through the two sets of threaded sleeves, which can be adjusted according to the size of the LED lamp body.

[0041] The utility model provides a clamping device for LED lamp testing, which can ensure that the LED lamp is stably clamped during the test process, avoiding test errors caused by shaking or displacement. At the same time, it can conveniently clamp LED lamps of different sizes and shapes without replacing the clamping components or performing complicated adjustments, thereby improving the flexibility of the test.
