BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1Shows a schematic structural diagram of the lamp holder of the utility model;

[0010] Figure 2 Shows a schematic structural diagram of the flat panel lamp of the present utility model;

[0011] Figure 3 The figure shows the installation diagram of the flat panel lamp and the lamp holder of the present invention. DETAILED DESCRIPTION

[0012] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0013] like Figures 1 to 3 A highway tunnel lighting device is shown, which includes a lamp holder 1 and a flat lamp. The lamp holder 1 and the flat lamp generally adopt a rectangular structure. The lamp holder 1 is fixed to the upper part 9 of the tunnel. A lamp trough 11 is provided in the middle of the lamp holder 1. A fixed rib 2 is provided on one long side wall 10 of the lamp trough 11, and a sliding rib 3 is provided on the other opposite long side wall 10. The sliding rib 3 is slidably mounted on the long side wall 10. A pushing device 4 is provided at the rear end of the sliding rib 3. The pushing device 4 can push the sliding rib 3 to slide inside the long side wall 10 outside the lamp holder 1. This design facilitates the installation and disassembly of the flat lamp and is convenient for maintenance and replacement.

[0014] The flat panel lamp consists of an outer shell 5 and a lamp body 6 located at the lower part of the outer shell 5. The shape of the outer shell 5 matches the lamp groove 11. The lamp groove 11 does not contact the inside of the outer shell 5. An installation groove 7 corresponding to the position of the fixed rib 2 and the sliding rib 3 is provided on the upper part of the long outer wall of the outer shell 5. A power supply interface 8 is provided on the upper part of the outer shell 5, and a power supply connector is provided inside the lamp groove 11. A certain margin is reserved for the wires of the power supply connector to ensure that the flat panel lamp can be stably installed in the lamp holder 1 and achieve reliable power supply.

[0015] As a further improvement, the pushing device 4 is a screw, which is installed on the long side wall 10 and is threadedly engaged with the long side wall 10. The end of the screw is rotatably connected to the rear end of the sliding rib 3. The movement of the sliding rib 3 can be achieved by rotating the screw, which is easy to operate.

[0016] As a further improvement, the pushing device 4 is a spring reset device, which is a press-type structure. The first press pushes the sliding rib 3 to be inserted into the lamp groove 11, and the second press pulls the sliding rib 3 out of the lamp groove 11. This structure is a prior art and will not be described in detail again.

[0017] As a further improvement, two fixed ribs 2 and two sliding ribs 3 are provided, and the fixed ribs 2 and the sliding ribs 3 are symmetrically arranged, so that the installation of the flat panel light is more stable.

[0018] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
