The term "and/or" as used herein includes any and all combinations of one or more related listed items.
[0036] Such as figure 1 As shown, it is a schematic structural diagram of a light emitting device 10 according to a preferred embodiment of the present invention.
[0037] The light-emitting device 10 includes a lamp holder 100, a body 200 disposed on the lamp holder 100 and a sliding rail 300. The lamp holder 100 includes a connecting portion 110 and two clamping portions 120 respectively disposed at both ends of the connecting portion 110, and the two clamping portions 120 are both located on the same side of the connecting portion 110, and the two clamping portions 120 are on opposite surfaces Both are provided with a first electrode (not shown). The main body 200 is disposed on the connecting portion 110, and is located on both sides of the connecting portion 110 with the clamping portion 120, and the main body 200 is electrically connected to the first electrode. Two opposite sides of the sliding rail 300 are provided with second electrodes (not shown in the figure) matching the first electrodes, and the extending direction of the second electrodes is the same as the extending direction of the sliding rail 300. The lamp holder 100 is sleeved with a sliding rail 300, the two clamping parts 120 clamp two opposite sides of the sliding rail 300, and the first electrode and the second electrode abut against each other.
[0038] When using the above-mentioned light emitting device 10, the slide rail 300 is arranged on the surface to be installed as required and arranged in the required shape, and then the lamp holder 100 is sleeved on the slide rail 300. When in use, the lamp holder 100 is slid on the slide rail 300 and placed in a desired position.
[0039] In the above-mentioned light emitting device 10, the lamp holder 100 drives the main body 200 to slide, and the lamp holder 100 can be placed in different positions of the slide rail 300 according to the needs during use, so that the use of the light emitting device 10 is more flexible and convenient, and its structure is simple and easy to operate. It is easy to produce and promote. Since the lamp holder 100 clamps the sliding rail 300, the second electrode on the sliding rail 300 is arranged on its side surface, and the first electrode on the lamp socket 100 is arranged on the two clamping parts 120, making it safer to use and increasing light emission The safety performance of the device 10.
