[0036] In this embodiment, the length directions of the first light trough 11 and the second light trough 12 are consistent, and the second light trough 12 is located at the side of the first light trough 11 along the length direction. Two second light troughs 12 are provided, and the two second light troughs 12 are respectively located at both sides of the first light trough 11 along the length direction and are symmetrically arranged. The length of the first light trough 11 is the same as the length of the second light trough 12, and both ends of the first light trough 11 and the second light trough 12 are through-arranged.

[0037] See also Figure 2 and Figure 3 The first lighting unit 3 is fixedly installed at the bottom of the first lamp trough 11. The first lighting unit 3 includes a first luminous body 31, a diffusion cover 32 and an anti-glare cover 33. The first luminous body 31 is fixed to the bottom of the first lamp trough 11 by screws. The diffusion cover 32 is located between the first luminous body 31 and the anti-glare cover 33. The anti-glare cover 33 blocks the opening of the first lamp trough 11.

The light-transmitting plate 42 blocks the opening of the second lamp trough 12 to evenly distribute the light emitted by the second light emitter 41. When the light emitted by the second light emitter 41 passes through the light-transmitting plate 42, it is scattered and refracted by the light-transmitting plate 42, thereby generating a large amount of secondary light. These secondary light sources will make the light more evenly distributed in the illuminated area, playing a role in uniform lighting and improving the lighting effect.

[0039] The inner wall of the second lamp trough 12 is provided with a mounting seat 13. In the present embodiment, the mounting seat 13 is integrally formed with the second lamp trough 12.
