Description

Technical Field

[0001] The utility model relates to the field of light guide plates, in particular to a high-temperature-resistant light guide plate with high light efficiency. Background Art

[0002] With the development of social science and technology and the improvement of people's living standards, lighting systems are becoming more and more developed and widely used. Light guide plates are an indispensable component in lighting systems.

[0003] The light guide plate is made of optical-grade acrylic / PC sheet material. Light guide dots are printed on the bottom surface of the optical-grade acrylic sheet using a combination of laser engraving, V-shaped cross-grid engraving, UV screen printing, and thermal transfer processes. The optical-grade acrylic sheet absorbs the light emitted from the lamp and stays on the surface. When the light hits each dot, the reflected light is diffused in all directions, breaking the reflective conditions and emitting from the front of the light guide plate.

[0004] Existing light guide plates (LGPs) typically consist of a diffusion layer, a main body layer, and a reflective film, with multiple reflective strips positioned along their sides. These simple structures and relatively limited functions also result in poor high-temperature resistance. LGPs are susceptible to aging and expansion due to high temperatures, which can squeeze out the reflective strips, damaging the LGPs and affecting their performance. Furthermore, LGPs are susceptible to corrosion from moisture, acidic substances, and other environmental factors, leading to aging and poor product quality, a short service life, and a poor user experience. Therefore, it is necessary to develop a new technical solution to improve existing LGPs to address these issues. Utility Model Content
