When the lamp panel 2 emits light, the intermediate light 501 is concentrated under the condensing action of the lens 3 and is emitted outwards through the light outlet 105, so as to obtain a linear light beam 503;

the existing lens 3 has poor condensing effect on both sides, so that the side light 502 on both sides cannot be condensed to the light outlet 105 by the lens 3, resulting in light energy waste.

Because the existing linear light source has a large waste of side light 502, the overall brightness of the linear light beam 503 is low, and in order to improve the brightness of the linear light beam 503, a method of increasing the power of the lamp panel 2 is generally adopted at present, however, increasing the power can cause the temperature of the lamp panel 2 to be high, and finally the service life of the lamp panel 2 is greatly shortened.

Therefore, there is a need for an improvement to the existing linear light source to solve the problem of insufficient brightness of the linear light beam emitted therefrom.

The above information disclosed in this background section is only included to enhance understanding of the background of the disclosure and therefore may contain information that does not form the prior art that is presently known to those of ordinary skill in the art.
