It should be noted that in other embodiments, other numbers of the position-limiting strips 923 can be disposed at the same end of the insulating box 92, and the arrangement of the position-limiting strips 923 can be in other forms.

Further, as shown in fig. 4, the lower end of the lamp housing 11 is open, a light-transmitting plate 130 is disposed at the lower end opening of the lamp housing 11, and a light-diffusing powder layer 140 is disposed on the light-transmitting plate 130.

The lamp housing 11 has openings at the left and right ends, and also has an opening at the lower end, a light-transmitting plate 130 is installed at the opening at the lower end, and light emitted by the light source 3 can be emitted outwards through the light-transmitting plate 130. The light-transmitting plate 130 may be specifically light-transmitting glass, light diffusion powder is coated on one side of the light-transmitting plate 130 close to the light source 3 to form a light diffusion powder layer 140, and by arranging the light diffusion powder layer 140, the light-emitting angle of the light source 3 is increased, glare is improved, light is softer and more uniform, and no harm is caused to human eyes.

Further, as shown in fig. 2 and 4, the light source 3 is mounted on the inner top surface of the lamp housing 11, and the reflective paper 150 is adhered to the inner side wall of the lamp housing 11.

The lamp housing 11 is of a cuboid structure, the interior of the lamp housing is hollow, the left end, the right end and the lower end are provided with openings, a light-transmitting plate 130 is arranged at the lower end opening, and end covers 12 are arranged at the left end opening and the right end opening; the light source 3 is mounted on the inner top surface (i.e. the surface opposite to the lower end opening) of the lamp housing 11 and is open towards the upper and lower ends; the reflective paper 150 is adhered to the inner side walls (i.e., the side walls between the left and right ends) of the front and rear sides of the lamp housing 11. The light emitted from the light source 3 can be refracted to the opening at the lower end of the lamp housing 11 by the reflective paper 150, so that the light can be emitted outwards through the transparent plate more intensively, and the light utilization rate is improved.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
