The specific embodiment:

Below in conjunction with accompanying drawing the utility model is further specified:

Consult shown in Figure 1ly, the utility model is to be light emitting source with LED, and LED 30 is welded on the wiring board 10, and is placed on the lamp socket together.LED also is communicated with cooling stand 20 through heat carrier 21, cooling stand 20 and wiring board 10 layered arrangement, and be parallel to each other.Consult shown in Fig. 2,3, be equipped with a plurality of louvres 22 and 11 on cooling stand 20 and the wiring board 10, form cold-hot air convection, accelerate heat radiation with this.

Shown in Figure 1, LED is that self has reflector through the conglomerate of encapsulation.Be welded on the wiring board 10 by pin 31, wiring board 10 leaves through hole and puts for the luminous end dew of LED, and the LED rear end is communicated with cooling stands 20 by heat carrier 21, reaches heat transmission, the realization heat radiation.

Consult shown in Fig. 4,5, the utility model is designed to a bulb form, be combined with a shell 50 on the lamp socket 40, shell 50 inner surfaces scribble reflectorized material, form reflective surface, reflect the light that LED sends with this, the side is provided with diffuser 60 before LED, diffuser 60 inner surfaces are laid with a plurality of lens 61, and diffuser 60 is combined to form an inner hollow body with shell 50, in just LED 30, wiring board 10 and cooling stand 20 being wrapped in.On diffuser 60, be drilled with the aperture (not shown), can allow extraneous air enter, and cooperate the louvre 22 and 11 on cooling stand 20 and the wiring board 10, make wiring board and cooling stand produce heat generation convection current, reduce temperature, promote heat radiation.Certainly, also suitably can form ventilating opening, allow extraneous air enter, cooperate louvre 22 and 11 on cooling stand 20 and the wiring board 10, form cold-hot air convection with this in diffuser 60 and shell 50 junctions.

Shown in Figure 5, lamp socket 40 includes middle base 41, power board 42, base 43 and connector 44, and middle base 41 peripheries leave steam vent 411 and are communicated with shell 50 inside, to get rid of heat.During installation, the positive and negative polarities from connector 44 weld an electric wire respectively earlier, and electric wire passes base 43 and receives connecting plate 42, with connector 44 and base 43 usefulness mould card jails, then power board 42 is fixed in the base 43 again; Weld an electric wire respectively from the positive and negative polarities of power board 42, and pass middle base 41 and shell 50, be connected on the LED, LED and wiring board 10 and cooling stand 20 are in advance to combine; Middle base 41 is locked on the power board 42, and shell 50 is locked on the middle base 41, LED and wiring board 10 and cooling stand 20 can be locked in middle base 41 by screw, diffuser 60 and shell 50 are combined at last to get final product again.

During enforcement, connector 44 is connected on the light fixture, connects power supply, each LED self is equipped with reflector and light source is concentrated into light beam casts out, cooperate shell 50 inner surface for reflecting effects, light beam carries out the light source diffusion through the various lens 61 on the diffuser 60, reaches the effect of illumination.Light source allows people's vision can not produce dazzle after lens 61 evenly spread, and illuminating effect is showing, and light is soft, the brightness height.Led color can be single color, also can change as required, perhaps also can change color from lens and make light source softer.

Wiring board 10 and LED be with fixedly conducting of scolding tin, wiring board 10 and cooling stand 20 screw relative fixed, and LED and cooling stand 20 contact points add Heat Conduction Material, and thermal source is imported cooling stand 20, are beneficial to heat radiation.Wiring board and cooling stand separate double-deck heat radiation, and reflector and wiring board temperature can not interact, and wiring board has a plurality of louvres with heat radiation rack, the increase cold-hot air convection, and reinforcement LED radiating rate can not produce high temperature; Simultaneously, be drilled with aperture on the diffuser 60 and enter, cooperate, wiring board and cooling stand are produced thermal source generation convection current, reduce temperature fast with the steam vent 411 that middle base 41 leaves by air.
