Shell 81 is formed with bydiapire 810 andsidewall 811 and surrounds thereceiving space 812 that forms, describeddiapire 810 by the heat sink material of good heat dispersion performance (such as, aluminium) make, and thesediapire 810 lateral surfaces outwards protrude out and are provided with somefins 813 formation one heat abstractors, describedfin 813 is made by the heat sink material of good heat dispersion performance, describedfin 813 is fixed in describeddiapire 810 withdiapire 810 one-body molded or hot transmission ground, such as adopting the common screw connecting mode of industry to be fixed, describedshell 81 can form by the metal material of good heat dispersion performance is one-body molded.And contiguous described receivingspace 812 also is formed with a powersupply resettlement section 814 in describedshell 81, is used to accommodate a power supply (not shown).

The describedlight source 82 that is formed by some great power LEDs is arranged on thecircuit board 83,circuit board 83 constitutes by one in the present embodiment, be tabular, alllight sources 82 are by being arranged in advance on thiscircuit board 83, certainly, this form that circuit board and configured light sources form are not limited in the present embodiment to be disclosed, such as, high-powerLED light source 82 can be arranged on four bar shaped circuit boards, every is separately fixed in LED Projecting Lamp 8shells 81 then.In addition, in order to reach the brightness that illumination needs, be not less than 1 watt at the power of great power LED described in the utility model.

During assembling, describedlight source 82 is arranged on thecircuit board 83, thencircuit board 83 is directly connected (passing through screw in the present embodiment) on theinner surface 8100 of describedshell 81diapires 810, againcover body 85 is installed on theshell 81 andshell 81 by snap close 86,circuit board 83,light source 82 andfin 84 etc. form on themain part 80 of LED light projector 8, described sealinggasket 89 is arranged between describedcover body 85 and theshell 81, reach sealing effectiveness, at last, describedmain part 80 is movably connected together by a syndeton 87 (adopting bolt in the present embodiment) and asupport 88, thereby finishes the assembling of LED Projecting Lamp 8.In use, LED Projecting Lamp 8 is fixed on the precalculated position, rotatesmain part 80 as required, make the emergent light of LED Projecting Lamp 8 be radiated at the target location and get final product by describedsupport 88.

Embodiment 2

See also shown in Figure 3, LED Projecting Lamp 8 in the present embodiment, comprise amain part 80 and withsupport 88,light source 82,circuit board 83,fin 84,cover body 85, snap close 86 and sealinggasket 89 that wherein saidmain part 80 comprisesshell 81, formed by some great power LEDs.

Identical among the shape ofshell 81 and structure and the embodiment 1, do not giving unnecessary details at this.The describedlight source 82 that is formed by some great power LEDs is arranged on thecircuit board 83,circuit board 83 constitutes by one in the present embodiment, be tabular, alllight sources 82 are by being arranged in advance on thiscircuit board 83, certainly, this form that the collocation form ofcircuit board 83 andlight source 82 is not limited in the present embodiment to be disclosed, such as, high-powerLED light source 82 can be arranged on four bar shaped circuit boards, every is separately fixed in LED Projecting Lamp 8shells 81 then.In addition, in order to reach the brightness that illumination needs, be not less than 1 watt at the power of great power LED described in the utility model.

Describedfin 84 is made by the heat sink material of good heat dispersion performance, is tabular; Describedcircuit board 83 as requested according to the precalculated position with afterfin 84 is connected, heat is fixed on describeddiapire 810medial surfaces 8100 with transmitting,fin 84 can pass through screw, bolt or heat-conducting glue etc. with the connected mode ofdiapire 810.

During assembling, describedlight source 82 is arranged on thecircuit board 83, thencircuit board 83 is fixed on theinner surface 8100 of describedshell 81diapires 810 earlier with afterfin 84 is connected, againcover body 85 is installed on theshell 81 andshell 81 by snap close 86,circuit board 83,light source 82 andfin 84 etc. form on themain part 80 of LED light projector 8, described sealinggasket 89 is arranged between describedcover body 85 and theshell 81, reach sealing effectiveness, at last, describedmain part 80 is movably connected together by a syndeton 87 (adopting bolt in the present embodiment) and asupport 88, thereby finishes the assembling of LED Projecting Lamp 8.In use, LED Projecting Lamp 8 is fixed on the precalculated position, rotatesmain part 80 as required, make the emergent light of LED Projecting Lamp 8 be radiated at the target location and get final product by describedsupport 88.

A key of the present utility model is that LED Projecting Lamp 8 adopts great power LED as illuminating source, reduced the overall volume of LED Projecting Lamp 8 greatly, not only reduced manufacturing cost, but also be convenient to transportation and use installation, simultaneously because the characteristic of the outgoing special angle light beam that LED itself has, make LED Projecting Lamp 8 not need reverberation bowl, thereby reduced manufacturing cost to a certain extent, also have because little many of the power of the existing scandium sodium vapor lamp of power ratio of LED when reaching same brightness, thereby reduced power consumption greatly, and then reduced use cost for the user.

Another key of the present utility model is that diapire 810 heat of great power LED and LED Projecting Lamp 8 shells 1 is fixed with transmitting and (can directly fixes, also can be fixing) by afin 84, thisdiapire 810 is made by the heat radiation material, described diapire 810 lateral surfaces outwards protrude out and are provided with somefins 813 formation one heat abstractors, describedfin 813 is rectangular sheet, concrete every width is consistent with the global shape of describedshell 81, when assurance is attractive in appearance, the heat energy that great power LED produces can be transmitted to diapire 810 peripheries andfin 813 rapidly, not only increased area of dissipation, and because most of area of dissipation inshell 81 outsides, has improved radiating effect effectively.

More than describing is embodiment of the present utility model only, forgives and can understand, and under the prerequisite that does not depart from the utility model design, all should be included within the technical conceive of the present utility model simple modification of the present utility model and replacement.
