Abstract
The invention relates to an LED side light television which comprises an outer frame, a light emitting LED and a heat radiating device which is connected with the LED and radiates out heat generated by the LED. The structure of the LED side light television can quickly radiate the generated heat to the outside, thereby effectively reducing the temperature of the LED and prolonging the service life of the LED side light television, and the LED side light television is safer to use.
Description
Technical field
The present invention relates to field of liquid crystal display, more particularly, relate to a kind of LED side light television.
Background technology
At present, adopt LED as of the ultra-thin favor that deeply be subjected to consumer of the side of light source liquid crystal TV set backlight owing to it.But existing employing LED, can't distribute rapidly because the LED caloric value is bigger as the side of light source liquid crystal TV set backlight, therefore has the shortcoming that the life-span is short, security performance is low.
Summary of the invention
The technical problem to be solved in the present invention is that because the LED caloric value is bigger, the defective that can't distribute rapidly provides a kind of LED side light television that can distribute rapidly the heat of LED generation at the above-mentioned of prior art.
The technical solution adopted for the present invention to solve the technical problems is: construct a kind of LED side light television, comprise housing, luminous LED, described LED side light television also comprises the heat abstractor that the heat that is connected with described LED and described LED is produced distributes.
In LED side light television of the present invention, described heat abstractor comprises the metal substrate that is connected with described LED, the radiating bottom plate that is connected with described metal substrate.
In LED side light television of the present invention, be provided with heat-conducting glue between radiating bottom plate and the described metal substrate.
In LED side light television of the present invention, described radiating bottom plate comprises first bending part that is connected with described heat-conducting glue, second bending part that is connected with described first bending part, reaches the 4th bending part that links to each other with described the 3rd bending part with described second the 3rd bending part that is connected.
In LED side light television of the present invention, described first bending part is parallel with described the 3rd bending part.
In LED side light television of the present invention, described second bending part is parallel with described the 4th bending part, and described first bending part is vertical with described second bending part, is provided with trip bolt between described metal substrate, heat-conducting glue, the radiating bottom plate.
In LED side light television of the present invention, described LED is four groups of LED that are distributed in the described housing, and described four groups of LED are arranged in the space that described first bending part, second bending part, the 3rd bending part surround.
In LED side light television of the present invention, be provided with light guide plate in the space that described the 4th bending part and described first bending part surround.
In LED side light television of the present invention, the second some pad that be disposed with diffusion barrier, the first some pad that plays the role of fastening, glass between described light guide plate and the described housing, plays the role of fastening.Implement LED side light television of the present invention, have following beneficial effect:
LED side light television of the present invention comprises housing, luminous LED, and described LED side light television also comprises the heat abstractor that the heat that is connected with described LED and described LED is produced distributes.Such structure can be dispersed into the external world to the heat that produces rapidly, reduces the temperature of LED effectively, has prolonged the life-span of LED side light television, and uses safer.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the front elevational schematic of LED side light television of the present invention;
Fig. 2 is the A-A generalized section of Fig. 1;
Fig. 3 is the B portion enlarged diagram of Fig. 2.
Embodiment
As shown in Figure 1 to Figure 3, in LED side light television first embodiment of the present invention, the LED side light television comprises housing 5, luminous LED6, and described LED side light television also comprises the heat abstractor that the heat that is connected with described LED6 and described LED6 is produced distributes.
Wherein, housing 5 is a square frame, square frame by sheet material bending drawing and forming.And heat abstractor just is installed on the inside of square frame.Heat abstractor comprises the metal substrate 3 that is connected with described LED6, the radiating bottom plate 1 that is connected with described metal substrate 3.For thus increasing heat radiation effect, LED6 is welded on the metal substrate 3, again metal substrate 3 and radiating bottom plate 1 are tightened together by screw 2.Certainly can also be by between metal substrate 3 and radiating bottom plate 1, scribbling heat-conducting glue 4, such radiating effect is better.
For the heat that LED6 is produced better distributes, radiating bottom plate is designed to comprise first bending part that is connected with described heat-conducting glue 4, second bending part that is connected with described first bending part, reaches the 4th bending part that links to each other with described the 3rd bending part with described second the 3rd bending part that is connected.And described first bending part can also be parallel with described the 3rd bending part.Described second bending part also can be parallel with described the 4th bending part, and described first bending part and described second bending part, described second bending part and the 3rd bending part, the 3rd bending part are vertical in twos with the 4th bending part.Result perpendicular to each other can increase area of dissipation in narrow space.
In the present invention, LED6 comes to end to end four groups, is distributed in respectively in the space that described housing 5 and described first bending part, second bending part, the 3rd bending part surround.Also be provided with light guide plate 11 in the space that the 4th bending part and first bending part surround, the effect of light guide plate 11 is that the photoconduction that LED6 produces is gone out.And also be disposed with diffusion barrier or increment film 10, the fastening first some pad 8, glass 9, the fastening second some pad 10 between light guide plate 11 and the housing 5.
In heat abstractor of the present invention, because LED6 is welded on the metal substrate 3, and metal substrate 3 is connected with radiating bottom plate 1 by heat-conducting glue 4, compress by screw 2, produce certain pressure, heat-conducting glue 4, metal substrate 3 and radiating bottom plate 1 are linked together closely, the basic applying, thereby the heat that LED6 is produced transmits by metal substrate 3-heat-conducting glue-radiating bottom plate 1, thereby realizes good heat radiation, so that the LED side light television life-span is longer, security performance is higher.
