The f-light source is usually placed in a closed space...but this fluorescent tube produces light energy in addition to it. It also generates heat energy. The optimal luminous efficiency temperature of @fluorescent tube is about f 45 C, and the right is the size of the liquid crystal display within 2 ,, that is, the light light official is below 10, and the temperature inside the display is still In an acceptable range, but as the panel size continues to increase due to market demand, it is necessary to increase the number of fluorescent tubes, and the number of lamps must be increased by one. A large amount of thermal energy will accumulate in the confined space, and the temperature inside the display will be too high (up to 70~80. 〇,). The result is that the luminous efficiency of the official is reduced, and the display is lowered. The reflective sheet at the bottom also produces yellowing or deterioration, which affects the reflection of light. At the same time, the diffuser and the light-passing sheet inside the display may be deformed due to excessive temperature, which may cause the phenomenon of color unevenness in the display. The heat dissipation method is roughly the use of air-cooled, water-cooled or heat-conducting 5 M299457-type heat-dissipation methods, all of which use a fan water-cooling device, and a 埶-ducted water-cooled type.
