Detailed description of the invention
Below in conjunction with detailed description of the invention and Figure of description, the present invention is described in further detail, but embodiments of the present invention are not limited to this.
With reference to figure 1 and Fig. 2, automobile LED headlamp, comprising: lampshade 1, lamp holder 2, turnover panel shade 3 and radiator 5, turnover panel shade 3 by the action of turnover panel realize headlamp near/distance light switches.Automobile LED headlamp also comprise LED luminescence chip 6 and LED No. bis-luminescence chips 4, LED luminescence chips 6 and LED No. bis-luminescence chips 4 be arranged at respectively radiator 5 above and side; Lamp holder 2 is provided with main lens 21 and widens mirror 23, main lens 21 and widen mirror 23 and be embedded in primary mirror mount pad 22 respectively and widen mirror mount pad 24, primary mirror mount pad 22 and widen mirror mount pad 24 and be individually fixed in fixed head 25; The light light of a LED luminescence chip 6 implements once light-distribution by the multistage free curve reflecting surface of reflector 7, then implements secondary light-distribution via main lens 21, to reach the requirement of dazzle lamp light type.The light level of LED No. bis-luminescence chips 4 projects by widening mirror 23, forms the auxiliary light of illumination.
With reference to figure 3 and Fig. 4, radiator 5 is provided with the first heat pipe 51, second heat pipe 52, fin 53 and heat emission fan 54, first heat pipe 51 and the second heat pipe 52 runs through radiator 5 respectively, and heat emission fan 54 is fixed on below fin 53.Realize the quick conductive to luminescence chip by two heat pipes, the fin 53 that heat passes to radiator 5 realizes heat-radiation heat-dissipating, for ensureing that radiating efficiency adds direct current heat emission fan 54 and strengthens cross-ventilation.
With reference to figure 2, main lens 21 is hemisphere round lens, can play the effect of optically focused, makes illumination intensity more concentrated; Widen mirror 23 for curved lenses, assisted diversion, opens when auxiliary optical port receives turn signal automatically, and illumination zone is to the expansion of headstock both sides, and namely range of exposures is wider.
With reference to figure 1, automobile LED headlamp also comprises reflector 7 and protective cover 8, and reflector 7 inwall is provided with multistage free curve reflecting surface, and reflector 7 is arranged at the top of a LED luminescence chip 6, and is fixed on the upper surface of described radiator 5; Described protective cover 8 is fixed on described radiator 5, and described reflector 7 is arranged between described protective cover 8 and described LED luminescence chip 6.The light light of a LED luminescence chip 6 implements once light-distribution by the multistage free curve reflecting surface of reflector 7, then implements secondary light-distribution via main lens 21, to reach the requirement of dazzle lamp light type.
First heat pipe 51 and the second heat pipe 52 are copper pipe, the material of radiator 5 is aluminium, LED luminescence chip 6 and LED No. bis-luminescence chips 4 contact with the second heat pipe 52 with the first heat pipe 51 respectively, the quick conductive to luminescence chip is realized by two heat pipes, the fin 53 that heat passes to radiator 5 realizes heat-radiation heat-dissipating, for ensureing that radiating efficiency adds direct current heat emission fan 54 and strengthens cross-ventilation.
The luminous power of a LED luminescence chip 6 is luminous powers of 15W, LED No. bis-luminescence chips 4 is 12W.
During specific works, LED luminescence chip 6 realizes basic automobile headlight illumination function (key light system), controls far/dipped beam switching with turnover panel shade 3.LED No. bis-luminescence chips 4 realize the function (auxiliary photosystem) of auxiliary light, point following four kinds of situations: A normally open, namely uses with key light system synchronization; B assisted diversion, opens when auxiliary optical port receives turn signal automatically, and illumination zone is to the expansion of headstock both sides, and namely range of exposures is wider, realizes turning without vision dead zone, directly can substitute now complicated mechanical servo steering headlight mechanism (AFS); C assists fog lamp, and when external environment condition is severe, driver can the auxiliary photosystem of manual unlocking (low visibility: heavy rain/dense fog etc.), makes illumination more abundant, avoids traffic accident; D intelligent lighting: by extraneous inductor or manually switch, can realize safe driving.
Intelligent lighting divides again five kinds of patterns,
A city pattern: dipped beam is opened, auxiliary light closes.Avoid light type scope excessive and cause meeting to be dazzle the eyes.
B suburb pattern: dipped beam is opened, auxiliary light is opened.Avoid light type scope too small, under roadbed, animal can not Timeliness coverage, walks crosswise suddenly road and produces security incident.
C fast mode: distance light is opened, auxiliary light is opened.With due attention to both short and long-range targets, vision is more abundant.Be suitable for and cross-country and section, ramp simultaneously.
D park mode: near/distance light closes, and auxiliary light is opened.Closely/the low-light (level)s such as applicable vehicle maintenance/camping/throw light on a large scale, reduce niphablepsia and energy resource consumption.
E bend pattern: automatically open when auxiliary optical port receives turn signal, illumination zone is to the expansion of headstock both sides, and namely range of exposures is wider.The just rear automatic distinguishing of steering wheel return realizes turning without vision dead zone.Directly can substitute now complicated mechanical servo steering headlight mechanism (AFS).
More than in conjunction with most preferred embodiment, present invention is described, but the present invention is not limited to the embodiment of above announcement, and should contain amendment that the various essence according to the present embodiment carries out, equivalent combinations.
