Abstract
An LED backlight radiating component comprises a back plate, an aluminum extrusion plate, a circuit board and a plurality of LED light sources, wherein the back plate consists of a bottom wall and a lateral wall formed by perpendicularly extending the edge of the bottom wall, the aluminum extrusion plate is arranged on the bottom wall of the back plate and provided with a base portion and a lateral portion formed by perpendicularly extending the base portion, the circuit board is adhered on the lateral portion of the aluminum extrusion plate approaching one surface of the base portion through heat conduction adhesive, and the LED light sources are electrically arranged on the aluminum substrate circuit board. Heat energy generated by the LED light sources is rapidly transmitted to the base portion from the lateral portion of the aluminum extrusion plate and then transmitted to the base portion through the base portion, contact area of the base portion of the aluminum extrusion plate and the back plate is increased greatly so as to lead the heat energy to be transmitted to the back plate high-efficiently, heat energy is transmitted to the center of the pack plate via the lateral wall of the back plate so as to facilitate radiating, and the aluminum extrusion plate further strengthens radiating effect, thereby effectively utilizing huge radiating area of the metal back plate, resolving the problem of waste heat generated by the LED, and guaranteeing service life of the LED. In addition, normal operations of other components on backlight such as a backlight module can be guaranteed.
Description
Technical field
The utility model relates to a kind of LED-backlit radiating subassembly.
Background technology
Traditional LCD is backlight, because adopt the CCFL cathode fluorescent tube as its light source, produces less heat.So this LCD backing structure does not need extra heat dissipation design basically.Therefore, traditional backboard does not have heat sinking function.
Also there be the backlight structure of a kind of LED of employing in the prior art as light source.But this LED cold light source type backlight has the more serious problem of heating, thereby causes the problem of component aging to occur easily, and then has shortened the service life of components and parts.
Therefore need provide a kind of radiating effect good LED-backlit radiating subassembly.
The utility model content
The utility model provides a kind of radiating effect good LED-backlit radiating subassembly.
For this reason, the utility model provides a kind of LED-backlit radiating subassembly, comprises by diapire and the backboard that constitutes from the sidewall that the edge-perpendicular of diapire extends to form; Be installed in the aluminium extruded template on the described backboard diapire, the sidepiece that described aluminium extruded template has base portion and vertically extends to form from base portion; Be attached on the sidepiece of described aluminium extruded template a lip-deep circuit board near described base portion by heat-conducting glue; Reach a plurality of led light sources that electrically are installed on the described aluminium base circuit board.
Advantage of the present utility model is: because the heat that sends of led light source is delivered to base portion rapidly from the sidepiece of aluminium extruded template, and then be delivered on the backboard by base portion, because the contact area of aluminium extruded template base portion and backboard increases greatly, thereby make heat faster efficient be delivered on the backboard, the sidewall of backboard transmits toward the center of backboard, thereby helps heat radiation; The existence of aluminium extruded template has also further strengthened radiating effect, and then effectively utilizes the huge area of dissipation of metal backing, has solved the used heat problem that LED produces, and guarantees the working life of LED; And other assembly on backlight is ensured such as the normal use of module backlight.
Below with reference to drawings and the specific embodiments the utility model is described further.

The specific embodiment
Shown in Fig. 1-5, the LED-backlit radiating subassembly 100 that the utility model provides comprises the backboard 10 of suitable shape such as rectangle.
Shown in backboard 10 preferably make such as aluminium by heat dispersion good metal material.Described backboard 10 comprises that diapire 12 reaches the sidewall 14 that extends to form from the edge-perpendicular of diapire 12.
LED-backlit radiating subassembly 100 further comprises the aluminium extruded template 20 on the diapire 12 that is installed in described backboard 10.The sidepiece 24 that described aluminium extruded template 20 has base portion 22 and vertically extends to form from base portion 22.
In addition, described LED-backlit radiating subassembly 100 further comprises circuit board, the aluminium base circuit board 40 that for example radiating effect is good.Preferably, described aluminium base circuit board 40 is attached to by heat-conducting glue 30 on the sidepiece 24 of described aluminium extruded template 20 near on the surface of described base portion 22.Described circuit board also can be FR4 fiber circuit plate.
Described LED-backlit radiating subassembly 100 further comprises a plurality of led light sources 50, and these led light sources 50 electrically are installed on the described aluminium base circuit board 40, so as by with aluminium base circuit board 40 cooperate and the power supply situation under luminous.
Because the heat that sends of led light source 50 is delivered to base portion rapidly from the sidepiece of aluminium extruded template, and then is delivered on the backboard by base portion because the contact area of aluminium extruded template base portion and backboard increases greatly, thereby make heat faster efficient be delivered on the backboard.The sidewall 14 of backboard 10 transmits toward the center of backboard 10, thereby helps heat radiation.In addition, the existence of aluminium extruded template 20 has also further strengthened radiating effect, and then effectively utilizes the huge area of dissipation of metal backing 10, has solved the used heat problem that LED40 produces, and guarantees the working life of LED40.And other assembly on backlight 10 is ensured such as the normal use of module backlight (figure does not show).
Described embodiment is the utility model preferred implementation; be not limited by the examples but only do not represent; other any do not deviate from any change, the modification made under the situation of spiritual essence of the present utility model and principle, substitutes, combination, simplify; all should be considered as the substitute mode with the utility model equivalence, all be included within the protection domain of the present utility model.
