Description

Technical Field

[0001] The utility model relates to the technical field of backlight sources, in particular to a backlight source structure with low power consumption. Background Art

[0002] The backlight source is a light source located behind the liquid crystal display. Its luminous effect will directly affect the visual effect of the liquid crystal display module. The liquid crystal display itself does not emit light. It displays graphics or the result of its light modulation. The internal structure of the existing backlight source is relatively simple. The improvement of light brightness requires the increase of light source power, which is not energy-saving enough. After the power is increased, the endurance of the light source will be reduced, and the service life is short. At the same time, the installation of the backlight source is mostly fixed by multiple bolts, which is troublesome to assemble and disassemble. The bolts are also easy to lose during the assembly and disassembly stage, which is not convenient enough to use. For example, CN217333070U, a low-power energy-saving backlight source disclosed in the China Patent Network, adopts a light refraction structure to improve the brightness of the light inside the backlight source, effectively reduce the power consumption of the backlight source product, and improve the endurance of the backlight source product. At the same time, the assembly and disassembly of the backlight source is faster and more stable, which has a usable value in the field of backlight application technology. The utility model light source is not easy to disassemble, so a low-power backlight source structure is proposed to solve the problems mentioned in the above background. Utility Model Content
