[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.

It can also be understood that the cross-section of the sliding rail 300 is "П"-shaped.

[0041] In order to further increase the safety of the light emitting device 10, for example, grooves 321 are formed on the opposite surfaces of the two second bending parts 320, the extending direction of the grooves 321 is the same as the extending direction of the sliding rail 300, and the second electrode is arranged On the bottom surface of the groove 321. For another example, the cross section of the groove 321 is trapezoidal, and the distance between the opposite side walls of the groove 321 gradually decreases from the bottom of the groove 321 to the opening direction. It can also be understood that the groove 321 is an inverted trapezoid shape.

It should be pointed out that the clamping groove can be provided on the first bending portion 310, the second bending portion 320, or in the groove 321, and the clamping portion can be provided accordingly.

[0046] The clamping groove and the clamping part make the lamp holder 100 and the sliding rail 300 more compact and stable, and are not easy to fall off, thereby increasing the stability of the light emitting device 10.

[0047] In order to further increase the connection and density of the lamp holder 100 and the sliding rail 300, for example, the two clamping portions 120 and the connecting portion 110 are connected by elastic members. Among them, the elastic member is a torsion spring. For another example, the two clamping parts 120 both extend with pressing parts, the two pressing parts and the main body 200 are located on the same side of the connecting part 110, and the two pressing parts are arranged oppositely.

[0048] The elastic force of the elastic member makes the clamping of the lamp holder 100 and the sliding rail 300 more stable, and the elastic member makes the lamp holder 100 more widely used, and can clamp the sliding rail 300 of different specifications. In addition, the elastic member prolongs the life of the lamp holder 100, so that it is not easily damaged during use.

[0111] The table 80 includes: a table top 810 and a light emitting device 10 arranged on the table top 810. The light emitting device 10 includes a lamp holder, a main body arranged on the lamp holder, and a sliding rail arranged on a table top 810. The lamp holder includes a connecting portion and two clamping portions respectively arranged at both ends of the connecting portion, and the two clamping portions are located on the same side of the connecting portion, and the two clamping portions are provided with first electrodes on the opposite surfaces. The main body is arranged on the connecting part, and the clamping part is respectively located on both sides of the connecting part, and the main body is electrically connected with the first electrode. Two opposite sides of the sliding rail are provided with second electrodes matching the first electrode, and the extension direction of the second electrode is the same as the extension direction of the sliding rail. The lamp holder is sleeved with sliding rails, the two clamping parts clamp two opposite sides of the sliding rails, and the first electrode and the second electrode abut against each other.

[0112] In the table 80, the lamp holder drives the main body to slide, and the lamp holder can be placed in different positions of the slide rail according to the needs during use, which makes the use of the light emitting device 10 more flexible and convenient, and has a simple structure and convenient operation, which is convenient for production and promotion. In addition, the light emitting device 10 is slidably arranged on the table 80, and the user can select the position of the light emitting device 10 according to needs, so that the table 80 has a wider application range.
