[specific embodiment]

The detailed applications content of relevant the utility model, at first see also Figure 1 and Figure 2, this luminaire movement 1 is formed by a light source radiation device 2 and a radiating part 3, light source radiation device 2 is provided with a collective optics 20 and a light-emitting component 21, in conjunction with after, be combined with a heat-conducting plate 22 at light-emitting component 21 heating positions, the used heat that light source radiation device 2 integral body are produced is via heat-conducting plate 22 leading directive property guidings.

Light source radiation device 2 and radiating part 3 between the two for combining, the caloic of heat-conducting plate 22 then, but handover and is dispersed for it in radiating part 3.

Radiating part 3 is in conjunction with a substrate 32 by majority fin 31 side by side, substrate 32 is provided with after trepanning 320 passes for light source radiation devices 2, the periphery of heat-conducting plate 22 then makes up with trepanning 320, but its syntagmatic periwinkle collecting silk interlocking, or with the heat-conducting glue gluing, or any press or mode such as buckle is reached, mainly be to allow the caloic of heat-conducting plate 22 can effectively pass to substrate 32, be distributed to each radiating fin 31 by substrate 32 again, and, the used heat exchange is given out by the surface area affinity cold conditions air of fin 31 expansions.

Above-mentioned formation, light-emitting component 21 (as shown in Figure 2) is luminous because of electric light work, wherein because of the used heat of resistance loss, can distribute toward Zhou Ji, this used heat includes potential caloic and heat wave, and this case is implemented in the periphery of light-emitting component 21, be subjected to collective optics 20 semi-open property encirclements, open opening provides light beam to penetrate, but in the collective optics 20 glass faces be to light-emitting component 21 to light beam reflect, and absorption is followed light beam and heat wave residual or that catch, therefore form long-pending heat, this long-pending heat must effectively be with and put, and this case is combined with a heat-conducting plate 22 at collective optics 20 roots, and 22 above-mentioned long-pending heat of traction of heat-conducting plate are past can thermally equilibrated direction transmission.

Heat-conducting plate 22 is a connection relationship with radiating part 3, then this used heat handover is exchanged by radiating part foundry and ambient, cool air, point to biography hot in nature, expel and make used heat can get definition by the guiding formation of heat-conducting plate 22, and then keep the physical property safety of light source radiation device 2, increase the service life.

Be marriage relation between collective optics 20 and the heat-conducting plate 22, this marriage relation is for reaching by any way, as one-body molded or any forms such as heat conduction gummed or interlocking, theming as heat-conducting plate 22 must satisfy the used heat that band draws collective optics 20, and its material is the tool thermal conductivity.

Please consult shown in Figure 3ly again, most movements 1 can make it the group body 100 that addition side by side enlarges the bright power of light stream according to the fin 31 direction serial of jumping, and its serial connection is for can adopt multiple compound mode, as providing installation side by side to prop up vacation or shell.

Please consult Fig. 4 and shown in Figure 5 again, enforcement through Fig. 2 or Fig. 3, can one cover plate 4 be arranged in fin 31 outsourcing device covers, after closing, cover makes between every adjacent fin 31, form a vertical stream 310, (especially as Fig. 3) vertically stream 310 can form the soaring path of thermal current according to organizing bodies 100 oblique θ arrangement of jumping, use and reach stack effect, with auxiliary radiating efficiency.

Vertically extra power also can be implemented as with the motor fan pressurization in stream 310 front and back ends, air-flow is increased state, and improves rate of heat exchange.

The movement 1 of above-mentioned Fig. 1～Fig. 5 is if implement waterproof ability to light-emitting component 21, and then movement 1 can be outer dewiness use, makes it heat radiation extremely to the greatest extent, improves electrooptic cell efficient.

It is shown in Figure 2 to return ginseng; radiating part 3 supports to link radiating fin 31 by substrate 32 basically; central authorities are provided with trepanning 320 and place for light source radiation device 2; and for 22 combinations of heat-conducting plate; the protection of collective optics 20 relatively; can directly be extended with containment body 34 toward it from substrate 32; this containment body 34 is identical to be provided with perforation 340 provides light source radiation device 2 to place; this containment body 34 extends from substrate 32; the fin 341 that thermolysis is therefore arranged equally, and constitute channel 342 by majority, this channel is through the enforcement of Fig. 3; the heat radiation that obtains Fig. 5 equally is auxiliary, makes to form another chimney effect.

This case mainly is at the generating device periphery, correlation combiner collective optics and heat-conducting plate, form the monomer of a light source radiation device, be combined as movement with radiating part, integral body has the movement that points to and easily distributes long-pending thermal effect, is the design of luminaire innovation at present.
