The specific embodiment
Below with the explanation of better enforcement kenel, and not the present invention is done to any pro forma restriction, refer to shown in accompanying drawing Fig. 1 to Fig. 3, it includes a radiating seat 1, one the one LED lamp 2, one the 2nd LED lamp 3 and a reflection subassembly 4 LED lamp device of the present invention, wherein: this radiating seat 1, its bottom has an installed surface 11; This first and second LED lamp 2,3 is arranged at intervals at this installed surface 11; And 4 pairs of this reflection subassemblies should installed surface 11, and this reflection subassembly 4 includes a far lamp reflecting surface 41 and a low beam reflecting surface 42, this is far away, low beam reflecting surface 41,42 is respectively to should second, one LED lamp 3,2, and this is far away, low beam reflecting surface 41,42 both curvature are not identical, this second, one LED lamp 3,2 projects respectively far and near illumination zone through the reflection of far away, low beam reflecting surface 41,42.
When the present invention uses and be low beam state in illumination, as shown in accompanying drawing Fig. 2, now LED lamp 2 its light of running present as dotted line lines and arrow, and a LED lamp 2 reflects and projects a low beam illumination zone through low beam reflecting surface 42.And the present invention while being far lamp state as shown in accompanying drawing Fig. 3, the 2nd LED lamp 3 throw lights present as dotted line and arrow, and the 2nd LED lamp 3 projects a far lamp illumination zone through 41 reflections of far lamp reflecting surface.In near or far lamp illumination zone, due to first and second LED lamp 2,3 all assembly in radiating seat 1 installed surface position, bottom, so the heat energy that first and second LED lamp 2,3 runnings produce all can directly be discharged by radiating seat 1 conduction, so can reduce first and second LED lamp 2,3 operating temperatures.
By understanding after above-mentioned explanation, the present invention is become respectively low beam illumination and throws light on far lamp by the projecting beam of a LED lamp 2 and the 2nd LED lamp 3, be available for users to according to environment, demands of individuals carry out choice for use, and then control near, the illumination zone of high beam, be different from and in prior art, adjust lamp source, reflection shield or lampshade distance each other, also be different from by magnetic valve and move the reflection angle of matte change lamp source after reflector etc., by avoiding mobile member, control closely, far lamp illumination, so do not have portable structure in the past, there is not complex structure, wear away the problems such as fast, and do not have in prior art, there is not mobile rear location that the disappearance of suitable illumination zone cannot be provided really, in addition this loose ripe seat 1 can directly conduct first, two LED lamps 2, the heat energy that 3 runnings produce, reduce by first, two LED lamps 2, 3 operating temperatures, to reach object of the present invention and effect.
Further illustrate LED lamp device provided by the present invention, wherein the installed surface 11 of this radiating seat 1 is a flat surface, and first and second LED lamp 2,3 is all positioned at the installed surface 11 of flat surface, so first and second LED lamp 2,3 is on same plane, therefore in the assembly of first and second LED lamp 2,3 and structural design simplified, and can suitably dwindle the convenient installation of overall volume, obtain great heat radiation effect.
In reflection subassembly 4 of the present invention this far lamp reflecting surface 41 compared with low beam reflecting surface 42 near installed surface 11.The 2nd LED lamp 3 projects far lamp illumination zone through 41 reflections of far lamp reflecting surface, and a LED lamp 2 projects low beam illumination zone through 42 reflections of low beam reflecting surface.In addition, this radiating seat 1 is made for heat-conducting copper or aluminium.
Refer to shown in Fig. 4, it operates simultaneously and through near, 42,41 reflections of far lamp reflecting surface, projects near, far lamp illumination zone respectively for first and second LED lamp 2,3 of the present invention, so under far lamp pattern, still possess the low beam vehicle anterior approach condition of throwing light in real time nearby, do not have and under far lamp illumination condition, lose low beam illumination functions, become and a kind ofly can possess near, far lamp illumination zone simultaneously.
LED lamp device provided by the present invention, further includes lens 5 that are arranged at this far lamp illumination zone path, and it is for second embodiment of the invention and refer to shown in accompanying drawing Fig. 5, and these lens 5 have the far lamp of adjustment illumination zone light shape function.The above-mentioned lens 5 of the present invention are to can be single convex lens, biconvex lens or Fo Ruinai lens (Fresnel lens), and in accompanying drawing, lens 5 be take biconvex lens as example.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment, all still belong in the scope of technical solution of the present invention.
In sum, the present invention is in structural design, use practicality and cost benefit, meet industry development completely required, and the structure disclosing is also to have unprecedented innovative structure, there is novelty, creativeness, practicality, the regulation that meets relevant patent of invention important document, therefore mention application in accordance with the law.
