Abstract
The utility model discloses a kind of radiating structure of LED-backlit module, comprise metal backing cover (1), lamp plate (2), reflector plate (4) and light guide plate (6); Lamp plate is 4, and every a slice lamp plate is provided with multiple LED (3), and 4 lamp plates stick on 4 side inside wall of framework respectively by heat-conducting glue; And LED is arranged inwardly; Light guide plate is fixed on the front end of metal backing cover; Reflector plate is 4, and 4 reflector plates are butted into the reflecting surface (5) of taper; Reflecting surface is between backboard and light guide plate; And reflecting surface is towards light guide plate; The lamp plate of the periphery of each LED is provided with the louvre (7) that multiple circumferences wait point arrangement.Reflector plate tilts 5 ° relative to light guide plate.The top of reflecting surface props up the central point at the light guide plate back side.The radiating structure of this LED-backlit module is ingenious and compact, and good heat dissipation effect is easy to implement.
Description
Technical field
The utility model relates to a kind of radiating structure of LED-backlit module.
Background technology
Existing LED-backlit module does not have special heat dissipation design, and radiating effect is undesirable, affects the service life of backlight module; Therefore, the radiator structure designing a kind of LED-backlit module is necessary.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of radiating structure of LED-backlit module, and the radiating structure structure of this LED-backlit module is ingenious and compact, and good heat dissipation effect is easy to implement.
The technical solution of utility model is as follows:
A radiating structure for LED-backlit module, comprises metal backing cover (1), lamp plate (2), reflector plate (4) and light guide plate (6);
The square backboard that described metal backing cover (1) comprises square framework and docks in this framework; Lamp plate is 4, and every a slice lamp plate is provided with multiple LED (3), and 4 lamp plates stick on 4 side inside wall of framework respectively by heat-conducting glue; And LED is arranged inwardly; Light guide plate is fixed on the front end of metal backing cover; Reflector plate is 4, and 4 reflector plates are butted into the reflecting surface (5) of taper; Reflecting surface is between backboard and light guide plate; And reflecting surface is towards light guide plate; Reflector plate tilts 3 ° ~ 10 ° relative to light guide plate;
The lamp plate of the periphery of each LED is provided with the louvre (7) that multiple circumferences wait point arrangement.
Reflector plate tilts 5 ° relative to light guide plate.
The top of reflecting surface props up the central point at the light guide plate back side.
Every a slice lamp plate is provided with 7 LED, and the periphery of each LED is provided with 4 louvres.
Beneficial effect:
The radiating structure of LED-backlit module of the present utility model, adopts metal backing cover, is conducive to improving heat radiation, in addition, the surrounding of LED is provided with multiple louvre, and therefore the heating of LED can pass through louvre, heat-conducting glue and metal backing cover rapidly derives, thus good heat dissipation effect.
In addition, the radiating structure of this LED-backlit module adopts the reflecting surface of 4 reflector plate compositions taper, and every a slice reflector plate is all obliquely installed, and the luminescence of LED is reflexed in light guide plate most possibly, and thus luminous efficiency is high, and structure is ingenious.
The top of reflecting surface props up the central point at the light guide plate back side, thus compact conformation, coordinates ingenious, and each parts are not easy to loosen, and is also conducive to heat radiation.
