Change speed, in some instances it may even be possible to cause to fail, seriously affect the working life of LED light, it is therefore desirable to which a series of cooling measures are to guarantee
The normal work of LED backlight.Existing side entering-type LED backlight mould group is LED light bar to be fixed on aluminium heat sink, but aluminium
The thermal coefficient of material be not it is very high, cause heat conduction apart from limited, heat cannot effectively be shed by heat, be driven simultaneously
Circuit can also generate partial heat at work.
Summary of the invention
In view of the above deficiencies, it the present invention provides a kind of good side entrance back module of heat dissipation, can not only solve to carry on the back
Optical mode group LED backlight heat dissipation problem, while the heat dissipation of driving circuit can also be solved, structure is simple, functional.
The present invention is achieved by the following technical solutions: a kind of good side entrance back module of heat dissipation, including backboard,
LED light bar and heat sink, the backboard bottom are equipped with for light source being fixed and thermally conductive pedestal, and the one of the pedestal
Side surface is equipped with heat sink, and another side surface is equipped with one group of radiating fin, and the heat sink includes: interconnection l-shaped
Horizontal component and vertical portion, the horizontal component lower part connect pedestal, top connects LED light bar, the vertical portion one
Side be provided with support light guide plate protrusion, the other side with connect backboard, the groove type between the adjacent fin of the radiating fin
At heat dissipation channel, radiator fan is equipped between the radiating fin, the air outlet of the radiator fan is opposite with heat dissipation channel.
It further include drive circuit board and thermal conductive belt, the drive circuit board as a preferred technical solution of the present invention
Pass through thermally conductive band connection with radiating fin.
As a preferred technical solution of the present invention, described thermal conductive belt one end is arranged between driving circuit and backboard,
The other end is arranged between heat dissipation scales and backboard.
Compared with prior art, the invention has the benefit that passing through setting heat sink, heat-conducting base and heat radiating fin
Piece forms the heat distributed when efficient heat dissipation channel, heat sink and heat-conducting base work LED backplane optics, quickly leads
Enter to radiating fin, heat dissipation channel formed by the groove between radiating fin, is blown by radiator fan to heat dissipation channel,
Make to form air-flow in heat dissipation channel, heat taken away and achievees the purpose that cooling, to improve heat-sinking capability, while radiating fin and
Heat transfer is carried out by thermal conductive belt between drive circuit board, heat when can be by drive circuit works is taken away.
