Description

technical field

[0001] The invention relates to a heat dissipation structure of an LED lamp backlight device. technical background

[0002] At present, the backlight sources of LCD TVs are mainly condenser lamps, and LCD TVs with LED lights as backlight sources have also begun to appear. There are two forms of led lights as backlight sources: side backlight (led lights are arranged on the side of the backlight board) and bottom backlight (led lights are arranged on the bottom surface of the backlight board). Compared with condensing lamps, LED lamps are energy-saving, have a long life, small size, and low temperature rise. They are regarded as the future development trend of LCD TVs.

[0003] Nevertheless, when the LED backlight device is in use, there is still a phenomenon of temperature rise, especially near the LED lamp, the temperature rise is more obvious. The temperature rise not only reduces the luminous efficiency of the led, but also makes the temperature of the l...
