Description
Technical field
The present invention relates to a kind of led light source, particularly relate to and a kind ofly being integrated on the metallic circuit framework and the LED light-emitting section that forms by a plurality of LED illumination light source unit.
Background technology
LED is commonly used on LCDs already, for example mobile phone and PDA (personal digital assistant) or the like.And in recent years owing to development of technology, the brightness of LED has had bigger lifting, and this makes LED also become the alternative of middle large scale liquid crystal display unit.The decomposing state that promptly is respectively a kind of existing LED-backlit source module illustrated in figures 1 and 2 down and the structural representation under the confined state.Wherein, LED1 is mounted correspondence position on the PCB (printed circuit board (PCB)) 2 by surface mount process (SMT), and electrically connects by electric wiring on the PCB and external power supply.But this kind light source module has following defective: one, because PCB is the platy structure of entity, so this light source module heat dispersion is very poor; Two, surface mount process processing procedure complexity, and cost is higher.
Summary of the invention
Technical problem to be solved by this invention is for the LED light-emitting section manufacturing process complexity that overcomes prior art and the defective of poor radiation, and a kind of LED light-emitting section of making simple and perfect heat-dissipating is provided.
The present invention solves above-mentioned technical problem by following technical proposals: the LED light-emitting section, its characteristics are, it comprises: a plurality of LED illumination light source unit, one circuit frame, respectively this LED illumination light source unit is electrically connected with this circuit frame respectively and forms a light-emitting section, also is provided with heat abstractor on this LED illumination light source unit.
Wherein, this heat abstractor is a plurality of radiating blocks that are embedded mutually with each LED illumination light source unit.
Wherein, this radiating block is a metal derby or ceramic block, or has the composite block of good heat radiating characteristic.
Wherein, this heat abstractor is a heat sink strip that is connected in series successively with each LED illumination light source unit.
Wherein, this heat sink strip is a bonding jumper.
Wherein, respectively this LED light emitting source is connected in series mutually or is in parallel, or series and parallel combines.
Wherein, this circuit frame is a metal framework.
Positive progressive effect of the present invention is:
1, LED light-emitting section employing of the present invention is combined by conducting bracket and heat abstractor and forms a LED striation, replaced the PCB that generally uses in the existing backlight source module, can in the manufacturing process of LED light-emitting section and light source module, save complex surfaces attachment process flow process and other relevant technological process thus, simplify manufacture craft.
2, than original PCB, this radiator structure that the present invention adopts has better heat dispersion.
3, the present invention will make the metal framework that technology supports usefulness in making LED device packaging technology, be designed to have the LED light-emitting section of circuit structure, be about to the circuit frame of metal framework discarded in the packaging technology as LED striation of the present invention, therefore, make no matter to be LED light-emitting section of the present invention, still the manufacturing cost of the led light source module of being made up of a plurality of these LED light-emitting sections will be cheaper also.

The specific embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to describe technical scheme of the present invention in detail.
The invention provides a kind of LED light-emitting section, it is by a plurality of LED illumination light source unit, the LED striation that a circuit frame is formed.Respectively this LED illumination light source unit is electrically connected with this circuit frame respectively and forms a striation shape.In order to accelerate the heat radiation of LED light emitting source, also be provided with a heat abstractor on the LED illumination light source unit.On being electrically connected, respectively this LED light emitting source can be gone here and there or entirely also entirely, or string and linking closes etc.
To shown in Figure 5, a plurality of LED illumination light source unit 101 are spaced successively by a circuit frame 201, wherein, a radiating block 301 are housed on each LED illumination light source unit 101 as Fig. 3.For heat radiation as early as possible, this radiating block 301 can be an a metal derby or thermal conductivity ceramic block preferably, and the composite block of other perfect heat-dissipatings etc.This radiating block 301 runs through from the bottom of LED illumination light source unit 101.The below of LED illumination light source unit 101 is horizontally set with a through hole in the place of wearing mutually with LED illumination light source unit 101.After this radiating block 301 wears with LED illumination light source unit 101, be coated and fixed in the bottom of LED illumination light source unit 101 after its inward at both ends bending, its cross section is a C word shape that Open Side Down.Certainly, after this radiating block 301 wears with LED illumination light source unit 101, also can two ends outwards be clamped in the both sides of LED illumination light source unit 101 after the bending respectively as another kind of conversion.Circuit frame 201 in the present embodiment can be other conductive frames such as a metal framework.
As shown in Figure 6 and Figure 7, present embodiment is with the different of a last embodiment, this circuit frame 202 is the pair of electrodes metal framework, and is located at the both sides of this LED illumination light source unit 102, and this heat abstractor is a heat radiating metal bar 302 that welds successively with each LED illumination light source unit 102.
LED light-emitting section employing of the present invention is combined by conducting bracket and heat abstractor and forms a LED striation, replaced the PCB that generally uses in the existing backlight module, can in the manufacturing process of LED light-emitting section, save complex surfaces attachment process flow process thus, simplify manufacture craft.In addition, than original PCB, this heat abstractor that the present invention adopts has better heat dispersion, and adopts metal framework in the packaging technology as led circuit framework of the present invention, and therefore, whole cost is also cheaper.
Though more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, under the prerequisite that does not deviate from principle of the present invention and essence, can make numerous variations or modification to these embodiments.Therefore, protection scope of the present invention is limited by appended claims.
