Description
Technical field
The present invention relates to lighting device for vehicle field, particularly a kind of independent distance light LED automobile lens.
Background technology
Volume is little, luminous efficiency is high, the life-span is long because having for LED, without the main feature such as stroboscopic, high brightness, be considered to one of potential light source of current most.In existing automotive illumination applications, the Glass lamp pearl based on tungsten filament as wick, lamp pearl volume is large, and luminous efficiency is low, and the life-span is short.Because lamp pearl volume is large, causing take tengsten lamp as the reflector that the headlight for vehicles needs of light source are larger, and lamp pearl exposed affect outside attractive in appearance.In addition, headlight for vehicles is divided into dipped headlights and high beam, and relative to dipped headlights, the range of exposures that high beam needs is less, but needs the distance of irradiation farther.The inadequate optically focused of high beam in existing headlight for vehicles, cause its brightness not high, irradiation distance is far away not.
Summary of the invention
The object of the invention is to the deficiency of the high beam for above-mentioned existing headlight for vehicles, propose a kind of independent distance light LED automobile lens, to extend car light service life, reduce car light volume, improve vehicle lamp brightness, increase irradiation distance.
For achieving the above object, the present invention includes cooling stand 1, lamp pearl 2, reflector 3, lens supports 4 and eyeglass 5; It is characterized in that: lamp pearl 2 is located in reflector 3, and be installed on together with reflector 3 on cooling stand 1, and the light-emitting area of this lamp pearl 2 is along at a certain angle with horizontal plane in the opposite direction with beam projecting side, the front end of cooling stand 1 is provided with lens supports 4, and the front end of lens supports 4 is provided with eyeglass 5.
Described cooling stand 1 comprises installing handle 11, mounting groove 12, radiating fin 13, radiator fan 14 and lens supports mounting bracket 15;
Described installing handle 11 is positioned at the afterbody of cooling stand 1, for LED automobile lens and car body being fixed;
Described mounting groove 12 is positioned at the centre of cooling stand 1, and its bottom surface is positioned at below horizontal plane, and its degree of depth shoals gradually along the exit direction of light, for installing lamp pearl 2 and reflector 3;
Described radiating fin 13 comprises lower surface or the upper surface that one or more is located at cooling stand 1, or upper and lower surface is equipped with, for increasing cooling surface area;
Described radiator fan 14 be positioned at cooling stand 1 foremost on the lower, and its air-flow formed blows to the afterbody of cooling stand 2, for lowering the temperature for cooling stand 1;
Described lens supports mounting bracket 15 is positioned at the front end of cooling stand 1, for installing lens supports.
Described lamp pearl 2 is by single or the plurality of LEDs chip packing forms as a lamp pearl.
Described reflector 3 is the reflective surface be made up of one or more curved surface, and the light for being sent by lamp pearl 2 converges to the focus place of eyeglass 5.
Described lens supports 4 is circular or oval or round rectangle structure, for fixing len 5.
Described eyeglass 5 is bull's-eye or oval convex lens or round rectangle convex lens, for by the mode level injection of the incident light through overfocus place by refraction.
The present invention compared with prior art has the following advantages:
(1) the present invention replaces tengsten lamp as light source owing to adopting LED, makes speed of lighting faster, energy-conserving and environment-protective more, longer service life;
(2) the present invention is less than the LED of tengsten lamp as light source owing to adopting volume, makes the smaller volume of reflector, further reduction lens volume, thus applicable more multi-vehicle-type, versatility is stronger;
(3) the present invention is owing to adopting the method that combines with eyeglass of reflector, makes emergent ray closer to directional light, and more by force, brightness is higher for light-gathering;
(4) the present invention is owing to have employed the mode of lamp pearl inclination installation, makes the utilization rate of whole lens on light higher.

Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
With reference to Fig. 1, LED automobile lens of the present invention, comprise cooling stand 1, lamp pearl 2, reflector 3, lens supports 4 and eyeglass 5; Wherein: lamp pearl 2 is located in reflector 3, and be installed on together with reflector 3 on cooling stand 1, the front end of cooling stand 1 is provided with lens supports 4, and the front end of lens supports 4 is provided with eyeglass 5.
See figures.1.and.2, described cooling stand 1 comprises installing handle 11, mounting groove 12, radiating fin 13, radiator fan 14 and lens supports mounting bracket 15; Installing handle 11 is positioned at the afterbody of cooling stand 1, for LED automobile lens of the present invention and car body being fixed; Mounting groove 12 is positioned at the centre of cooling stand 1, and its bottom surface is positioned at below horizontal plane, and its degree of depth shoals gradually along the exit direction of light, for installing lamp pearl 2 and reflector 3; Radiating fin 13 comprises many fins and is located at the lower surface of cooling stand 2 for increasing cooling surface area; Radiator fan 14 be positioned at cooling stand 1 foremost on the lower, and its air-flow formed blows to the afterbody of cooling stand 2, for lowering the temperature for cooling stand 1; Lens supports mounting bracket 15 is positioned at the front end of cooling stand 1, for installing lens supports.
With reference to Fig. 3, lamp pearl 2 adopts plurality of LEDs chip as the packing forms of a lamp pearl, its light-emitting area edge and the beam projecting side α at a certain angle with horizontal plane, 0 °≤α <90 ° in the opposite direction.When high beam is opened, lamp pearl 2 is lit, its light sent is mapped on reflector 3 inwall, be made up of curved surface inside reflector 3, light reflection is converged to the focus A place of eyeglass 5, the light converged is mapped to eyeglass 5, and to penetrate close to the mode of directional light after the refraction of eyeglass 5, many emergent lights converge the distance light hot spot forming high brightness; In above process, some light is as emergent ray I
3, after the reflection of reflector 3, though through overfocus A, be not utilized owing to not being mapped to the surface of eyeglass 5; Because there is α at a certain angle lamp pearl in the present invention 2 and axis, can reduce to a greater extent as emergent ray I
3such situation occurs, improves the utilization rate of whole lens on light, increases lens brightness.
Below be only a preferred example of the present invention, do not form any limitation of the invention, obviously under design of the present invention, different changes and improvement can be carried out to its structure, but these are all at the row of protection of the present invention.
