The specific embodiment

From the schematic diagram of Fig. 2 as can be known, the profile of present embodiment is made up of fin a3, reflector a1, translucent cover a2 and interior ring a7 etc.Wherein, fin a3, translucent cover a2, interior ring a7 lay respectively on the emitter a1; fin a3 can be used in the heat radiation of light fixture; translucent cover a2 carries out certain protection to lamp interior; can adjust emergent ray simultaneously, interior ring a7 can firmly be fixed on translucent cover a2 in the reflector a2 by the structure of import.

Fin a3 is after mutual superposition, can turning up or tilt in its edge, wherein turns up or the angle that tilts can be regulated according to different needs, to reduce the space density of fin a3 to greatest extent, the contact area and the convection velocity of increase and air improve radiating efficiency.In manufacturing process, be smooth planar structure around the center of fin a3, so that stack is conducted heat fast; The surface, marginal portion of fin a3 then can be made into uneven, striped, can increase the contact area of fin a3 and air equally, helps to improve radiating efficiency.

Fin a3 is separate structure, and the surface is provided with two or more fluting a31.Fluting a31 not only can be positioned at the edge of fin a3, also can be other positions.Corresponding mutually between each fluting a31, form many group heat dissipation channels, to form the channel of a ventilation, increase cross-ventilated speed.

Fin a3 is that copper, the contour heat conductive metal of aluminium or alloy are made, and can carry out the quick conduction of heat.Considering reasons such as material cost and technology, generally adopt aluminum alloy materials to make fin a3.

As shown in Figure 3, present embodiment is made up of fin a3, screw a5, substrate a6, led light source a4, reflector a1, translucent cover a2, interior ring a7 etc.Wherein, fin a3, substrate a6 and reflector a1 press by screw a5, and mutual superposition is in aggregates, and led light source a4 is fixed on the substrate a6, and the edge of fin a3 is turned up or tilted.

Led light source a4 can fill Heat Conduction Material between led light source a4 and substrate a6 in the fixation procedure of substrate a6, as heat-conducting cream etc., to increase contact area between the two, improve heat conductivility.On fixed form, can adopt screw, buckle, welding etc. that led light source a4 is combined closely on the surface of substrate a6.Wherein, led light source a4 quantitatively can adopt single-chip package or the integrated encapsulation of multicore for one or more, and the wavelength of light source can be visible or black light wave band, or mixed light.

Reflector a1 is a bowl structure, and inner surface is a parabolic shape, but does not limit to this shape, can be for rules or irregularly shaped such as square, straight tubulars, to adapt to different light fixture profile needs.The inner surface of reflector a1 has passed through plated film or polishing, can improve the reflecting effect of light.Making on the material, reflector a1 adopts metal or total making such as copper, aluminium, to play the effect of auxiliary heat dissipation.

Be manufactured with the cross section at the edge of reflector a1 for being similar to the step a11 of " L ", be fixed with interior ring in the step.Wherein the corner at " L " is provided with a chamfering, the fastening installation of ring a7 in can cooperating.End at interior ring a7 is provided with wiredrawn edge a71, can link closely to cooperate the fastening installation of interior ring a7, and lens cap a2 is fixed in the reflector a1.

Fig. 4 is the three-dimensional exploded view of this example, and in the drawings, we can be clearly seen that threes such as fin a3, reflector a1, substrate a6 closely are superposed to an integral body by screw a5 in order.Led light source 4 is fixed in substrate a6, and the heat that produces is passed to reflector a1 and fin a3 fast, dispels the heat.Wiredrawn edge a71 by the interior ring a7 reflector a1 inside of linking closely, translucent cover a2 is fixed in reflector a1.

Substrate a6 is a circular configuration, and the smoothness on surface can be improved through polishing or coating film treatment in the surface, to increase the reflecting effect of light.Substrate a6 adopts highly heat-conductive materials such as metal, alloy or pottery to make, and has good thermal conductivity.
