Abstract

The invention is a cooling fixed device and its cooling method, with the help of a fixed part clamped on a heat conductivity fixed framework, transmitting the heat produced by the light source to the heat conductivity fixed framework and discharging the heat.

Description

technical field [0001] The invention relates to a heat dissipation method of a light source, in particular to a heat dissipation method of a light source using a material with high thermal conductivity and elasticity, and it can be applied to a backlight module. Background technique [0002] With the development of digital network technology, it has gradually affected the work and life of human beings in the 21st century. Liquid crystal screens (LCD) have been widely used in all aspects of daily life. The LCD panel industry is not only based on notebook computers (NB) as the core application, but also includes LCD computer screens, portable consumer audio-visual products, The market application of information home appliances such as mobile phones and LCD TVs is fully developed. [0003] Using a backlight-type backlight unit as a way to increase LCD brightness is a widely used way. At present, various forms of backlights have the advantages of stable luminous efficiency and...
