Description

The efficient radiating apparatus of LED light source supporting body

Technical field

The present invention relates to LED lighting technical field, or rather, relate to the efficient radiating apparatus of LED light source supporting body.

Background technology

Along with the development and maturation of 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 LED is widely used at lighting field.Compared with the energy-saving lighting lamp of LED and general photo-voltaic power supply adapted, there is long, the outstanding advantages low, not fragile, power consumption is little and more energy-conservation that generates heat of life-span, 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, conventionally many light emitting diodes mode is in accordance with regulations arranged on aluminium base and forms lumination of light emitting diode supporting body, by aluminium base, dispel the heat.In order to reach heat radiation requirement, often need to increase the thickness of aluminium base, increased so on the one hand the weight of whole lighting, be inconvenient to use, the opposing party also certainly will increase manufacturing cost, and for high-power LED lighting fixture, it is especially obvious that this defect seems.Such as, the high-power LED street lamp of 120 watts of left and right of dispelling the heat by aluminium base, its weight is probably 9 kilograms of left and right, wherein most increases the thickness of aluminium base in order to reach the needs of 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; For too high fin, in especially integrated situation, also higher to the requirement of mould on the other hand, and the yield rate of product can decrease, and this has also increased manufacturing cost to a certain extent; And even so, it is also 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 defect that prior art exists, and a kind of efficient radiating apparatus of LED light source supporting body is provided.

For addressing the above problem, the technical solution used in the present invention is:

The efficient radiating apparatus of LED light source supporting body, it comprises some LED, LED supporter and circuit board, described LED is installed on described LED supporter, it is characterized in that: described LED supporter is made with the foam metal with through-hole structure; In the receiving space forming at described foam metal part surface or at foam metal, configure a cooling fan; Described circuit board is made with Heat Conduction Material aluminium, and between described circuit board and described LED supporter, heat-conducting glue is set.

Preferably, described foam metal is the one in foam iron, foam copper, foamed aluminium, foam iron alloy, foam copper alloy, foam aluminium alloy;

Preferably, select the foam metal between being 10-50 of hole count on per inch;

Preferably, on described foam metal surface, form one at least partly for supporting the metal supporting layer of described LED light source, and described metal supporting layer and foam metal are combined as a whole by the mode of electroplating;

Preferably, the part except being formed with metallic support layer region in described cooling fan is configured in to described foam metal surface;

Preferably, in described foam metal surface, except being formed with the part of metal supporting layer, in remaining surface, there is part to be closed;

Preferably, described circuit board heat is conductively being fixed in described metal supporting layer;

Preferably, in the described metal supporting layer solid metal layer that the material identical with foam metal make of serving as reasons.

Compared with prior art, the present invention configures cooling fan when forming foam metal layer on supporter in foam metal layer receiving space surperficial or that form at foam metal layer, make the heat of LED light source supporting body generation when passing to foam metal layer rapidly, by the flowing velocity of 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, by hot gas is mobile fast, quickly the heat of LED light source supporting body generation is taken away, played extraordinary radiating effect.In addition, adopt foam metal can also save a large amount of metal materials, also significantly reduced the weight of whole luminous supporting body simultaneously, not only economy but also easy to use.

The specific embodiment

The present invention discloses LED light source supporting body heat abstractor, wherein said LED light source supporting body comprises some LED and LED supporter, described LED is installed on described LED supporter, and major technique design is that (1) makes described LED supporter with the foam metal with through-hole structure; (2) in the receiving space forming at described foam metal part surface or at foam metal, configure a cooling fan.

As shown in Figure 1, this figure is a kind of new LED light source supporting body 8 according to design design of the present invention, it 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 10 of being made by the good Heat Conduction Material of heat conductivility (as aluminium) of described LED, described LED is configured in and on circuit board 10, forms some LED light-emitting sections (not label), certainly in order to obtain, better going out light effect, can be also every LEDs configuration lens devices 11 according to actual needs, described LED supporter 2 comprises foam metal layer 21 and at least part of for supporting the metal supporting layer 20 of described LED, described foam metal layer 21 by the foam metal with through-hole structure (as foam iron, foam copper, foamed aluminium, foam iron alloy, foam copper alloy, foam aluminium alloy) form, on this foam metal per inch, hole count is 10-50, adopt in the present embodiment foam copper, 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 in the present embodiment foam copper, 20 of metal supporting layer are solid metal copper layer, described metal supporting layer 20 engages and is integrated with foam metal layer 21, preferred mode is for to make metal supporting layer 20 engage and be integrated with foam metal layer 21 by plating.Described LED supporter 2 also disposes a cooling fan 23, this cooling fan 23 is configured in the part except being formed with metal supporting layer 20 regions in foam metal layer 21 surfaces, Fig. 1 with in Fig. 2, illustrated that cooling fan 23 is arranged on the foam metal layer one side set up relative to metal supporting layer 20.Described LED is fixed on described LED supporter 2 by circuit board 10, in the present embodiment, described LED is fixed in 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, at circuit board 10, be close between metal supporting layer 20 Heat Conduction Material also can be set, such as heat-conducting glue etc.When LED light source supporting body 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 rapidly to foam metal layer 21, by the 3 D stereo network structure of foam metal 21 inside, the long-pending first mate of air and heat source-contacting surface is increased, cooling fan 23 rotates 3 D stereo network structure and the through hole by foam metal 21 inside simultaneously, the flowing velocity of foam metal layer 21 inner airs will be accelerated, the heat fast LED being produced is taken away, and plays extraordinary radiating effect.In addition, adopt foam metal can also save a large amount of metal materials, also significantly reduced the weight of the luminous supporting body 8 of whole LED simultaneously, not only economy but also easy to use.
