Description
[technical field]
The present invention relates to the LED lighting technical field, or rather, relate to a kind of led light source module.
[background technology]
Development and maturation along with the LED technology, the performance indications of LED increase substantially day by day, the light efficiency of white light LEDs has has met or exceeded the light efficiency level of ordinary incandescent lamp at present, and luminous flux is also increasing considerably, and makes LED obtain using widely at lighting field.LED compare with the energy-saving lighting lamp of general photo-voltaic power supply adapted have the life-span long, heating is low, not fragile, power consumption is little and more energy-conservation outstanding advantage, people it be described as 21 century replace fluorescent lamps and incandescent lamp the 4th generation lighting source.
At present, when using light emitting diode, usually many light emitting diodes mode in accordance with regulations is installed in and forms the lumination of light emitting diode module on the aluminium base, dispel the heat by aluminium base.In order to reach the heat radiation requirement, often need to increase the thickness of aluminium base, increased the weight of whole lighting so on the one hand, be inconvenient to use, the opposing party also certainly will increase manufacturing cost, and for high power LED lighting lamp, it is especially obvious that this defective seems.Such as, high power LED road lamp of about 120 watts by the aluminium base heat radiation, its weight is probably about 9 kilograms, wherein most increases the thickness of aluminium base for the needs that reach heat radiation and the height of fin produces, this has increased the weight of whole street lamp on the one hand greatly, make installing/dismounting all inconvenient, and increased material cost; On the other hand for too high fin, under the especially integrated situation, also than higher, and the yield rate of product can decrease to the requirement of mould, and this has also increased manufacturing cost to a certain extent; And even so, it also is difficult to arrive desirable radiating effect on the whole.
[summary of the invention]
The technical problem that the present invention solves is to overcome the defective that prior art exists, provide a kind of in light weight, cost is low and the good led light source module of radiating effect.
The present invention is achieved by the following technical solutions: a kind of led light source module, comprise some LED and LED supporter, described LED is installed on the described LED supporter, described LED supporter comprises a foam metal layer and a cooling fan that is formed by the foam metal with through-hole structure, and described cooling fan is configured in the foam metal laminar surface or is configured in the receiving space that forms in the foam metal layer.
Described foam metal can be a kind of in foam iron, foam copper, foamed aluminium, foam iron alloy, foam copper alloy, the foam aluminium alloy.
Hole count is 10～50 on the described foam metal per inch.
Described LED is fixed on the circuit board of being made by Heat Conduction Material, and described LED is fixed on the described LED supporter by circuit board.
Be provided with heat-conducting glue between described circuit board and the LED supporter.
Described LED supporter also comprises part surface that is formed at foam metal layer and the metal supporting layer that is used to support described LED to small part.
Described metal supporting layer is one with foam metal by electroplating to engage.
Described cooling fan is configured in the part except that being formed with the metallic support layer region in the described foam metal laminar surface.
Except that the part that is formed with metal supporting layer, there is part to be closed in the remaining surface in the described foam metal laminar surface.
The described metal supporting layer solid metal layer that the material identical with foam metal made of serving as reasons.
Compared with prior art, the present invention is by improving the LED supporter that supports led light source, on supporter, form foam metal layer, simultaneously in foam metal laminar surface or the receiving space that in foam metal layer, forms, dispose cooling fan, make heat that the led light source module produces when passing to foam metal layer rapidly, flowing velocity by air in the 3 D stereo network structure of cooling fan acceleration foam metal inside, when guaranteeing that the long-pending first mate of heat source-contacting surface increases, quickly the heat of led light source module generation is taken away by hot gas is mobile fast, played extraordinary radiating effect.In addition, adopt foam metal can also save a large amount of metal materials, also reduced the weight of whole illuminating module simultaneously significantly, not only economy but also easy to use.

[specific embodiment]
Embodiment one
See also illustrated in figures 1 and 2, led light source module 8 of the present invention comprises led light source part 1 and LED supporter 2, wherein said led light source part 1 comprises some LED (not shown) and carries the circuit board of being made by the good Heat Conduction Material of heat conductivility (as aluminium) 10 of described LED, described LED is configured in and forms some LED light-emitting sections (not label) on the circuit board 10, certainly better going out light effect in order to obtain, also can be every LEDs configuration lens devices 11 according to actual needs; Described LED supporter 2 comprises foam metal layer 21 and is used to support the metal supporting layer 20 of described LED to small part, described foam metal layer 21 by foam metal with through-hole structure (as foam iron, foam copper, foamed aluminium, foam iron alloy, the foam copper alloy, foam aluminium alloy) forms, hole count is 10～50 on this foam metal per inch, adopt foam copper in the present embodiment, described metal supporting layer 20 is formed at the part surface of foam metal layer 21, the solid metal layer that this metal supporting layer 20 is made by the metal material identical with foam metal, such as adopting foam copper in the present embodiment, 20 of metal supporting layer are solid metal copper layer, described metal supporting layer 20 engages with foam metal layer 21 and is one, and preferred mode is one for by plating metal supporting layer 20 is engaged with foam metal layer 21.Described LED supporter 2 also disposes a cooling fan 23, this cooling fan 23 is configured in foam metal layer 21 surfaces part except that being formed with metal supporting layer 20 zones, in Fig. 1 and Fig. 2 cooling fan 23 has been shown and has been arranged on foam metal layer and the metal supporting layer 20 relative one sides of setting up.Described LED is fixed on the described LED supporter 2 by circuit board 10, in the present embodiment, described LED is fixed on the metal supporting layer 20 by circuit board 10, circuit board 10 is close to metal supporting layer 20 and is contacted as far as possible in large area with it, be close between the metal supporting layer 20 at circuit board 10 and also Heat Conduction Material can be set, such as heat-conducting glue etc.When the led light source module is worked like this, the heat that LED produces passes to metal supporting layer 20 by heat conduction circuit board 10, by metal supporting layer 20 heat is passed to foam metal layer 21 rapidly, 3 D stereo network structure by foam metal 21 inside, the long-pending first mate of air and heat source-contacting surface is increased, cooling fan 23 rotations simultaneously are by the 3 D stereo network structure and the through hole of foam metal 21 inside, the flowing velocity of foam metal layer 21 inner airs will be accelerated, the heat that LED is produced is taken away fast, plays extraordinary radiating effect.In addition, adopt foam metal can also save a large amount of metal materials, also reduced the weight of whole LED illuminating module 8 simultaneously significantly, not only economy but also easy to use.
