Obviously, the described embodiments are only part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

When a component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components can also be present.

The terms "vertical", "horizontal", "left", "right", and similar terms as used herein are for purposes of description and illustration only.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0035] Referring to Figure 1 FIG. 1 is a schematic diagram of a lamp strip aging test device according to a preferred embodiment of the present application. In Figure 1 The device includes a lifting mechanism 1 and first and second test mechanisms 2 and 3 in the embodiment shown.

[0036] As Figure 2 , Figure 3 The lifting mechanism 1 is composed of a horizontal profile frame 100 and a vertical profile frame 101. The horizontal profile frame 100 is equipped with two guide assemblies 102 and a lifting drive source 103, the output end of which is connected to a main gear 104. The top of the vertical profile frame 101 has an upper protective cover 105, below which is disposed a driven gear 106 (see Figure 4 ), which is connected to the main gear 104 by a drive belt (not shown). The drive belt is fixed with a pressing block 107, which is mounted on a connecting plate 108. The connecting plate 108 is fixed with two slidable lifting plates 109 on both sides, the upper ends of which have support surfaces for directly contacting and supporting the lamp strip 4.

[0037] The first test mechanism 2 is installed on one side of the lifting mechanism 1 to electrically connect one end of the lamp strip 4, while the second test mechanism 3 on the other side electrically connects the other end of the lamp strip 4, ensuring that the lamp strip 4 receives power from both ends at the same time, which can more evenly perform aging test, especially for longer lamp strips 4.

[0038] In the specific test process, the long lamp strip is connected to the first test mechanism 2 and the second test mechanism 3 located on both sides of the lifting mechanism 1 through a specified circuit connection mode. The first test mechanism 2 and the second test mechanism 3 can simultaneously supply power to both ends of the lamp strip 4, ensuring that both ends of the lamp strip 4 can obtain sufficient voltage, avoiding the problem of insufficient voltage. In addition, in order to cope with the large space required by the long lamp strip, a lifting mechanism 1 is designed, which drives the drive belt by driving the main gear 104, and then drives the pressing block 107 connected to the drive belt. These pressing blocks 107 are attached to the connecting plate 108, which in turn drives the lifting plate 109 to move up and down in the vertical profile frame 101. Since the lamp strip 4 is placed on the support surface, the lamp strip 4 is pulled into an n-shaped or inverted V-shaped structure, which can effectively utilize the vertical space to arrange the lamp strip 4. This design allows the height of the lifting plate 109 to be adjusted according to the length of the lamp strip 4, so that the aging test of the long lamp strip 4 can be completed even in a space-limited environment. When a longer lamp strip 4 needs to be tested, more lifting mechanisms 1 can be added, as shown in Figure 1 , the lifting mechanism 1 is arranged in 5 groups, and each group of lifting mechanisms 1 can simultaneously test four lamp strips 4, improving the effect.

[0039] As shown in Figure 2 , the upper end of the support surface is provided with a heat insulating piece 110, and the heat insulating piece 110 and the support surface are both provided with heat dissipation holes 1101. The lamp strip 4 is placed on the upper surface of the heat insulating piece 110, which can effectively prevent the heat generated during the test of the lamp strip 4 from being transmitted to the lifting mechanism 1, ensuring the stable operation of the mechanism and the safety of the lamp strip test.

[0040] As shown in Figure 4 , the vertical profile frame 101 is provided with a sliding rail 111, and the lifting plate 109 is installed on the sliding rail 111, allowing the lifting plate 109 to move smoothly up and down on the vertical profile frame 101, thereby realizing the height adjustment and position optimization of the lamp strip 4 during the test.

[0041] As shown in Figure 5 , in the lamp strip aging test device, the first test mechanism 2 and the second test mechanism 3 both contain an electric box 20 equipped with a test assembly 21.

[0042] As shown in Figure 6 , the test assembly 21 is composed of a bottom plate 210, a vertical plate 211 and a horizontal plate 212, wherein the vertical plate 211 is vertically installed on the bottom plate 210, and the horizontal plate 212 is vertically installed on the vertical plate 211 and parallel to the bottom plate 210. The horizontal plate 212 is equipped with a first lifting cylinder 213, the output end of the first lifting cylinder 213 is connected to a test plate 214, the test plate 214 is installed with a probe 215, so that the test plate 214 can be accurately adjusted in position by the first lifting cylinder 213, and the probe 215 directly contacts the lamp strip 4 to be tested.

[0043] Preferably, the base plate 210 is provided with two plate width adjustment blocks 216, which allow the user to adjust the plate width as needed to adapt to different widths of light strips 4 or testing requirements.

[0044] like Figure 7 As shown, in this LED strip aging test device, a pressing assembly 22 is provided on one side of the electrical box 20, near the lifting mechanism 1. This pressing assembly 22 includes a base 220 on which a lower pressing plate 221 is mounted. Multiple second lifting cylinders 222 are mounted on the lower pressing plate 221, and the output ends of the second lifting cylinders 222 are connected to an upper pressing plate 223. The upper pressing plate 223 and the lower pressing plate 221 are arranged opposite to each other, forming a pressing space 224 for pressing the LED strip 4; this allows the LED strip 4 to be securely clamped and positioned before testing, ensuring accuracy during the testing process.

[0045] Please refer to Figure 5 In the design of this LED strip aging test device, an arc plate 23 is added to the electrical box 20, located between the pressing assembly 22 and the guide assembly 102. The arc plate 23 serves as a guide, ensuring that the LED strip 4 guided from the guide assembly 102 can smoothly enter the pressing assembly 22 along the arc-shaped path; it optimizes the transmission path of the LED strip 4 and reduces potential damage caused by sharp edges.
