When in use, the slider moves along the slide groove to adjust the position of the lamp body, which is easy to adjust and will not cause secondary damage to the exhibition hall ceiling; secondly, the U-shaped frame rotates around the slider to adjust the horizontal direction of the lamp body, and the lamp body flips up and down around the U-shaped frame to adjust the vertical direction of the lamp body; the support ribs on the periphery of the base and the mounting ring form heat dissipation gaps between adjacent support ribs, which increases the heat dissipation space of the lamp body, improves the heat dissipation effect, and also ensures the firmness of the structure; the top of the lamp body is threadedly connected to the mounting ring, and the bottom of the lamp body is inserted into the groove of the base, which has good firmness and stability of the connection and is easy to disassemble and assemble. When the lamp body is damaged, it can be unscrewed and replaced; when the lamp holder is damaged, just move the slider out of the slide groove, which is very convenient for disassembly and replacement, with high maintenance efficiency and low maintenance cost.

[0005] Furthermore, mounting protrusions are provided on both sides of the mounting ring, and threaded holes are provided on the two mounting protrusions. Mounting holes are formed at the two ends of the U-shaped frame corresponding to the threaded holes, and a first bolt is also included that passes through the mounting hole and is threadedly connected to the threaded hole, and the first bolt presses the U-shaped frame on the mounting protrusions. This design has a simple structure and a good fixing effect after the U-shaped frame is turned over.

[0006] Furthermore, the cross section of the slide groove is T-shaped, and rollers are formed on both sides of the slider corresponding to both sides of the slide groove. This design makes the slider move more smoothly.

[0007] To sum up, the beneficial effects of the utility model are as follows: this product can adjust the position of the lamp body through the slider and slide groove design, which is easy to operate and will not cause secondary damage to the exhibition hall ceiling; when the lamp holder is damaged, only the slider needs to be moved out of the slide groove, and disassembly and replacement are very convenient; the supporting ribs and heat dissipation gaps on the periphery of the base and the mounting ring facilitate the heat dissipation of the lamp body and ensure firm installation; the lamp body is threadedly connected to the mounting ring, and the bottom of the lamp body is inserted into the groove of the base, which has a firm connection and good stability, is easy to disassemble and assemble, and when the lamp body is damaged, it can be unscrewed and replaced, which is convenient for maintenance.

DETAILED DESCRIPTION

[0012] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0013] like Figure 1-3The present invention shows an exhibition hall lighting device, which includes two monomers and a mounting strip 3. All monomers are slidably mounted on the same mounting strip 3. Of course, the monomers can be one or more than two. Specifically, each monomer includes a lamp holder 1 and a lamp body 2. The lamp body 2 is selected from existing products, such as embedded cob ceiling scattered light spotlights, anti-glare LED embedded ceiling lamps, etc. The lamp body 2 is installed on the lamp holder 1, and the mounting strip 3 is fixed to the ceiling of the exhibition hall by expansion screws. The lower surface of the mounting strip 3 is provided with a slide groove 31, and the slide groove 31 extends along the length direction of the mounting strip 3. The lamp holder 1 includes a slider 11, a U-shaped frame 12, and a lighting tube 13, wherein the slider 11 is movably arranged on the slide groove 31, the U-shaped frame 12 opens downward, and the lighting tube 13 is hinged between the two ends of the U-shaped frame. The middle of the U-shaped frame 12 is rotatably connected to the lower surface of the slider 11, and also includes a rotating shaft, which passes through the middle of the U-shaped frame 12 and is connected to the lower surface of the slider 11, and the U-shaped frame 12 can be flexibly rotated around the rotating shaft. The lighting tube 13 has a base 131 , a mounting ring 132 and supporting ribs 133 .

[0014] The supporting ribs 133 connect the periphery of the base 131 and the mounting ring 132, and a heat dissipation gap is formed between adjacent supporting ribs 133. The outer wall of the top of the lamp body 2 is provided with an external thread, and the inner wall of the mounting ring 132 is provided with an internal thread. The lamp body 2 is threadedly connected to the mounting ring 132. A groove 135 is formed on the base 131, and the groove 135 is used to accommodate the bottom of the lamp body 2. The groove 135 is circular, and the bottom of the lamp body 2 is preferably also cylindrical. The bottom of the lamp body 2 just fits into the groove 135 and does not affect the rotation of the lamp body 2.

[0015] The mounting ring 132 has mounting protrusions 134 on both sides of the lower end, and threaded holes are provided on the two mounting protrusions 134 . Mounting holes are formed at the corresponding threaded holes at both ends of the U-shaped frame 12 , and also includes a first bolt 4 .
