In the through hole of embedded light emitting source.
The radiator structure that embodiment of the present invention provides, the backlight that can be used in liquid crystal display, by by backlight
Light emitting source in source is embedded into the through hole in heat sink body, can effectively improve the area of dissipation of light emitting source in backlight, subtract
The heat being transferred to less on light guide plate and blooming piece, so as to improve the radiating effect of whole backlight, it can avoid due to light
Display caused by learning diaphragm and light guide plate temperature distortion is bad.
Referring to Fig. 1, Fig. 1 is a kind of schematic diagram for radiator structure that embodiment of the present invention provides, and the radiator structure includes
Heat sink body 10, the heat sink body include connected Part I 11 and Part II 12, wherein, it is provided with Part I 11
Multiple through holes 13, each through hole 13 are used to be embedded in a light emitting source, and Part II 12 is used as heat-conduction part, light emitting source is sent
Heat conduct to other structures, for example, when the radiator structure be used for liquid crystal display in backlight when, its Part II
It can be in contact with the backboard in backlight, so as to which the heat that sends light emitting source is conducted to giving out on backboard；
Preferably, in order to further improve the radiating effect of light emitting source, the shape of through hole can be with hair on heat sink body
The shape of light source matches, as shown in Fig. 2 when light emitting source 21 is embedded in through hole, inwall and the light emitting source 21 of through hole are brought into close contact,
The heat that light emitting source is sent conducted to other structures by the radiator structure in time, if for example, liquid crystal display
Backlight uses the LED of square, then the through hole of correspondingly-shaped can be opened up on heat sink body, when LED be embedded into it is logical
It when in hole, can be brought into close contact four side walls of LED and the inwall of through hole.
