The specific embodiment

The utility model embodiment sees also Fig. 1 to Fig. 7, is the selected embodiment of the utility model shown in the figure.

The utility model first embodiment provides a kind of LED illuminating lamp 10 of tool heat abstractor, and to shown in Figure 5, illuminating lamp 10 includes 1, luminous group 2 of a heat abstractor, at least one optically focused frame 3, light-passing board 4 and a fixed mount 5 as Fig. 1, wherein:

Heat abstractor 1 comprises an integrated body 11 and two heat conducting bar groups 12; Wherein, body 11 central authorities are arranged with a lamp socket 111, lamp socket 111 tools one thermal conductive surface 112, this thermal conductive surface 112 is a plane, and the periphery in lamp socket 111 protrudes out a protuberance 113, and in body 11 contiguous lamp socket 111 two relative sides several fixing holes 114 (each is an example with three screws among the figure) is set respectively, whereby, be for being provided with luminous group 2 in regular turn and at least one optically focused frame 3, covering again and establish light-passing board 4 and fixed mount 5 in the lamp socket 111.Again, be close to lamp sockets 111 and distinguish tool one radiating part 115 in body 11 away from two sides in opposite directions of fixing hole 114, each radiating part 115 all has a plurality of radiating fins 116, radiating fin 116 and body 11 are for being wholely set, and radiating fin 116 is the same sides that are positioned at this body 11 with this luminous group 2, radiating fin 116 and uniformly-spaced to be provided with, in order to effectively to distribute the heat that absorbs from this body 11 thermal conductive surfaces 112.In addition, in body 11 radiating parts 115 away from biend wear several thermal holes 117 respectively, in order to each heat conducting bar group 12 to be set.

The thermal conductivity factor of each heat conducting bar group 12 is the thermal conductivity factors that are higher than this body 11, and in the present embodiment, above-mentioned body 11 can utilize aluminium to make, and two heat conducting bar groups 12 all can copper become.This two heat conducting bars group 12 is respectively with a mobile jib 121 vertical several bars 122 that connect, each bar 122 is placed through the thermal hole 117 of two side radiating parts 115 respectively, and extend in the lamp socket 111 of this body 11 and adjacent arrangement (seeing Fig. 4 and shown in Figure 5 for details), so that heat conducting bar group 12 can comparatively fast be transmitted heat, simultaneously, and make each mobile jib 121 be fixed in this body 11, this fixes with screw closure, be placed through inferior bar 122 in this body 11 in order to the location, conduct the extremely external world of luminous group 2 heat that is produced fast by the heat conducting bar group 21 of high thermal conductivity coefficient.

Formed (among the figure be example with 12 groups of light emitting diode module) by at least one light emitting diode module 21 for this luminous group 2, each light emitting diode module 21 is to be controlled by a circuit board 22 simultaneously, and this luminous group 2 abuts against thermal conductive surface 112 in this body 11 with a radiating surface 23 (in contrast to the face that light source is provided).In addition, between the radiating surface 23 of the thermal conductive surface 112 of body 11 and luminous group 2, a heat conduction material (not shown) can be set, and heat conduction material can utilize the coating thermal grease, for effective conduction heat.

In aforementioned, optically focused frame 3 is example in this with 12, and it is to be positioned in the lamp socket 111 of this heat abstractor body 11 with the light source that cooperates this each light emitting diode module 21 of luminous group 2.Moreover this light-passing board 4 is provided with to cooperate lamp socket 111, and it is to be covered on each optically focused frame 3, and is positioned protuberance 113 end faces of these body 11 lamp sockets 111 peripheries, in order to protect luminous group 2.

This fixed mount 5 is the peripheries that are covered on this transparent panel 4, and this fixed mount 5 is fixed in lamp socket 111 peripheries of this heat abstractor body, and with this transparent panel 4 of location on this lamp socket, wherein, can utilize several fixtures (screw) that fixed mount 5 is fixed in the fixing hole 114 of these lamp socket 111 2 sides, come the positioning and fixing frame to abut against light-passing board 4, optically focused frame 3 in regular turn by fixture and make it be positioned lamp socket 111.

So, said structure, owing to lamp socket 111, radiating part 115 all are the same one sides that are positioned at body 11, and the another side of body 11 (back side) can make it be applied to multiple occasions such as street lamp, wall lamp or general illumination lamp for fixing this illuminating lamp usefulness.

When luminous group 2 light emitting diode module 21 luminous and when producing heat of high temperature, see also shown in Figure 5, because luminous group 2 radiating surface 23 is to abut against on the thermal conductive surface 112 of aforementioned body lamp socket 111, and luminous group 2 heat that produces can be passed to thermal conductive surface 112 via radiating surface 23 rapidly, because the thermal conductive surface 112 of lamp socket 111 is to be set to one with this radiating part 115, and can be via the radiating part 115 of lamp socket 111 thermal conductive surfaces 112 sides of heat conduction to two fast quick heat radiating, and because body 11 is directly to be exposed in the atmosphere, relative, also can be directly by body 11 quick distribute heats.In addition, be higher than body owing to be placed through the thermal conductivity factor of two heat conducting bar groups 12 in the body 11, and the inferior bar 122 adjacent arrangements of each heat conducting bar group 12, and be adjacent to the thermal conductive surface 112 of lamp socket 111, and can conduct heat to faster by the inferior bar 122 of two side heat conducting bar groups 12 in mobile jib 121 and the atmosphere, whereby can quick heat radiating.

Therefore, with the one-body molded body that lamp socket and radiating part are arranged so that luminous group heat directly conducts through radiating part to atmosphere, and have can quick heat radiating advantage; And, to wear the heat conducting bar group of high thermal conductivity coefficient, distribute heat, and the life-span of improving light emitting diode module more fast.

Offering a piece of advice it, on the assembling moving-wire, is to establish for overlapping in regular turn group with body, luminous group, optically focused frame, transparent panel and fixed mount earlier, and overall structure is simple, the assembling moving-wire is simplified, and assembling can be finished fast easily, and cost is low relatively.

Certainly, the utility model still has other example, wherein only difference in the part variation.Please seeing Fig. 6 and Fig. 7 in addition, is in order to showing the second preferable embodiment of the utility model, and the difference of itself and a last embodiment is:

The utility model second embodiment need not be provided with aforementioned fixation frame 5, because the fixing hole 114 of body 11 contiguous these lamp sockets 111 of aforementioned heat abstractor 1, in this second embodiment, its applied fixing hole 114A is arranged at protuberance 113A end face, and this light-passing board 4

A has several perforation 41A, and with several fixtures (screw) that cooperates this fixing hole and perforation 41A, passes this perforation 41 respectively and is fixedly arranged on fixing hole on this protuberance 113A, in order to fix this light-passing board.

Therefore, owing among the utility model second embodiment, exempted the use of fixed mount, not only can letter economize whole cost, it is powerful also to reach aforesaid institute.
