Description
[technical field]
The present invention relates to a kind of light-emitting diode light bar structure, particularly relate to a kind of light-emitting diode light bar structure with heat sinking function.
[background technology]
Panel of LCD (LCD panel) now has been widely used in the electronic product of tool growth potentiality such as monitor, notebook computer, digital camera and projector.The LCD panel manufacturers is after producing glass substrate, must be earlier in conjunction with colored filter, both pour into liquid crystal behind the involution, be together to form notebook computer or the LCD monitor manufacturer that the LCD module is sold to the downstream with assemblies such as backlight module, drive IC, control circuit boards again.
Backlight module (Back light module) is one of key part and component of panel of LCD, because liquid crystal itself is not luminous, the function of backlight module promptly is well-off brightness and the light source that is evenly distributed, and makes its normally show image.Backlight module is mainly assembled by assemblies such as light source, lampshade, reflecting plate (Reflector sheet), LGP (Light guide plate), diffusion sheet (Diffuser sheet), brightness enhancement film (Brightness enhancement film) and housings.
Generally speaking, backlight module can be done classification with the position of fluorescent tube according to the requirement of its scale, develops side-light type (Edge lighting) structure and full run-down type (Bottom lighting) structure.Wherein, the light emitting source of side-light type structure is the single Zhi Guangyuan of pendulum at side; Under the light source of full run-down type structure then is positioned over.The used fluorescent tube of backlight module must possess characteristics such as brightness height and life-span length, cold cathode fluorescent lamp pipe (Cold cathode fluorescent lamp is arranged at present, CCFL), hot-cathode fluorescent light tube, light emitting diode (Light emitting diode, LED) and electroluminescence (EL) etc.
Wherein, the cold cathode fluorescent lamp pipe has characteristics such as high briliancy, high efficiency, life-span length, high color rendering, therefore adding that cylindrical outer shape is easy to be combined into lamellar lighting device with light reflection element, therefore, once was the main flow of backlight module with the backlight of cold cathode fluorescent lamp Guan Weizhu.Yet therefore the cold cathode fluorescent lamp pipe, is eliminated by trend in today that environmental consciousness is surging gradually because pipe contains mercury vapour.Because light emitting diode (LED) has advantages such as energy-conserving and environment-protective as back light than cathode fluorescent tube (CCFL), therefore replacing CCFL with LED will be the trend of development backlight, and industry claims the luminous lamp bar (Light bar) that is configured to of light emitting diode usually.
