[detailed description of the invention]
Please refer to shown in Fig. 1 to Fig. 2, the LED 1 of the present invention first preferred embodiment, comprise light source supports 11, heat abstractor 12 and be positioned at the drive unit 13 of heat abstractor 12 inside at least partly, light source supports 11 is fixed on heat abstractor 12, and heat abstractor 12 comprises at least two stators 121 that main part 120 and main body extend.Light source supports 11 has the location division 110 corresponding with stator 121 position, and stator 121 has the connecting portion 1210 be connected with main part 120 and the afterbody 1212 extended from connecting portion 1210.Afterbody 1212 and the main part 120 of heat abstractor 12 of stator 121 lay respectively at the both sides of the light source installation direction of light source supports 11, thus light source supports 11 and heat abstractor 12 are fixed.The stator 121 that the present invention is extended by heat abstractor 12 and light source supports 11 fix, thus light source supports 11 and heat abstractor 12 are fixed, thus make fixing between the light source supports 11 of this LED 1 and heat abstractor 12 not need to relend to help exterior part, as screw, fastener etc., structure is simple, easy for installation.
The connecting portion 1210 of stator 121 passes the location division 110 of light source supports 11, and afterbody 1212 bends, thus has angle with connecting portion 1210 shape.In the present embodiment, afterbody 1212 is roughly vertical with connecting portion 1210, thus plays spacing effect.In the present embodiment, the fluting of all round closure of location division 110, namely location division 110 is positioned at the non-edge portions of support member 11, in other embodiments, location division 110 also can be the opening at the edge being arranged at support member 11, has certain position-limiting action to stator 121.
The main part 120 of heat abstractor 12 comprises the support portion 1201 of supporting light sources support member 11 and self-supporting portion 1201 to the extension 1202 extended with light source supports 11 rightabout.Stator 121 self-supporting portion 1201 extends, and stator 121 and extension 1202 lay respectively at the both sides of the light source installation direction of support portion 1201.Extension 1202 can expand area of dissipation, and heat abstractor 12 can better be dispelled the heat.In the present embodiment, heat abstractor 12 is formed by the one-body molded bending again of sheet metal.In other embodiments, heat abstractor 12 also can divide and to be body formedly formed by connecting again.
Extension 1202 has the slit 1203 being positioned at extension 1202 sidewall, and extension 1202 is divided at least two parts by slit 1203, makes extension 1202 outwards or inwardly elastic deformation can occur.In the present embodiment, connection support portion, extension 1202 one end 1201, one end is free end, makes heat abstractor 12 be formed as the hollow cylinder of one end open.When the quantity of slit 1203 is three, extension 1202 free end then can outwards move arbitrarily respectively as required or move inward.
Extension 1202 is the cylinder of hollow, and drive unit 13 major part is arranged in the extension 1202 of heat abstractor 120.Owing to having slit 1203 can there is elastic deformation in sidewall to heat abstractor 13, and when making drive unit 13 be positioned at heat abstractor 13 inside, mounting design is all more flexible.
LED 1 also comprises wire (not shown), wire connecting drive device 13 and light source supports 11.The slit 1203 of wire self-heat irradiation device 120 passes thus is connected with light source supports 11.Can find out, slit 1203 has flexible effect except playing the extension 1202 making heat abstractor 120, can also provide passage for wire.
LED 1 also comprises optical cover 14 and insulation shell 15.Heat abstractor 12 is arranged in insulation shell 15, and optical cover 14 is fixed on insulation shell 15.
Insulation shell 15 has fastening rib 151, and the extension 1202 of heat abstractor 12 is the closer to the part of support portion 1201, and elasticity is less, and fastening rib 151 abuts the part of extension 1202 near support portion 1201.Because the support portion 1201 of heat abstractor 12 does not have elasticity, cannot expand or diminish, therefore extension 1202 is less the closer to the partial elastic of support portion 1201, when heat abstractor 12 inserts insulation shell 15, extension 1202 bottom can be shunk according to the inner space of insulation shell 15 or expand, and fastening rib 151 abuts the part of extension 1202 near support portion 1201, better can fix the position of heat abstractor 12, make heat abstractor 12 more stable, avoid rocking.In the present embodiment, insulation shell 15 upper wider, bottom is narrower, when heat abstractor 12 loads insulation shell 15, near the portion retracts of insulation shell 15 bottom, support portion 1201 can be positioned at insulation shell 15, also can be positioned at optical cover 14 inner, or be positioned at insulation shell 15 and optical cover 14 junction.
Light source supports 11 has the flat part 112 be connected with heat abstractor 12.Flat part 112 is connected with the support portion 1201 of heat abstractor 12.In the present embodiment, light source supports 11 is plate shaped light source board, and light source particle 113 is fixed on the side of the opposing extension 1202 in heat abstractor 12 of light source board.In other embodiments, light source supports 11 also can be solid figure, light source particle 113 also can be fixed on the sidewall of light source supports 11 to expand rising angle of LED etc., as long as light source supports 11 has the flat part 112 be connected with support portion 1201.
In the present embodiment, stator 121 is fixing for bending, and in other embodiments, the afterbody 1212 of stator 121 can also be limited in the side of light source supports 11 as required by other means, thus heat abstractor 12 and light source supports 11 is fixed.Please refer to shown in Fig. 3 and Fig. 4, in the present invention second preferred embodiment, the connecting portion 2210 of stator 221 passes the location division 210 of light source supports 21, and afterbody 2212 has the narrower pressure mouth 2213 in wider one end, at least one one end.In second preferred embodiment, afterbody 2212 and connecting portion 2210 are positioned at same plane, afterbody 2212 presses off thus makes afterbody 2212 away from one end of connecting portion 2210 wider than near one end of connecting portion 2210 by pressure mouth 2213, and afterbody 2212 away from one end of connecting portion 2210 wider than the width of location division 210.Like this, stator 221, through forming a pressure mouth 2213 behind location division 210, makes the afterbody of stator 221 be limited in the side of the opposing main part 220 in heat abstractor 22 of light source supports 21, thus light source supports 21 and heat abstractor 22 is fixed.In second preferred embodiment, location division 210 is three openings being roughly uniformly distributed in the edge of support member 21, and at least comprise the first side wall 2101 and the second sidewall 2102, stator 221 is limited in this location division 210.Because location division 210 is uniformly distributed, therefore, it is possible to support member 21 is limited between three location divisions 210.Location division 210 is arranged at light source supports 21 edge, more can saves the space of the supporting surface (non-label) of light source supports 21.
Should be noted that, embodiments of the invention have preferably implementation, and not any type of restriction is done to the present invention, any person skilled in art of being familiar with may utilize the technology contents of above-mentioned announcement change or be modified to equivalent effective embodiment, in every case the content of technical solution of the present invention is not departed from, the any amendment done above embodiment according to technical spirit of the present invention or equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
