Abstract
The utility model discloses a light distribution structure of an automobile headlamp and a light-emitting diode (LED) automobile headlamp with the structure. The light distribution structure comprises a light shield, an LED light source and an LED lens, and is characterized by also comprising a reflector and a tongue-shaped reflector, wherein the tongue-shaped reflector is arranged on the lower part of the light shield; and the LED lens covers the light-emitting surface of the LED light source and is arranged in the reflector to form a whole, and the whole is arranged in the light shield. By the light distribution structure of the automobile headlamp, a duck tongue-shaped light distribution curve is formed, the irradiation intensity of horizontally upward light is limited in a certain range when two automobiles meet, the problem of glare caused by automobile lamps at night can be solved, and light energy is fully utilized under the reflecting action of the tongue-shaped reflector. The light distribution structure is suitable for various LED automobile headlamps.
Description
Technical field
The utility model relates to a kind of headlight for vehicles light distribution structure and uses the LED headlight for vehicles of this structural design; With the irradiation height of effective control automobile lamp light in cruising; Reduce light pollution; Avoid light that opposite driver or pedestrian are dazzle the eyes, belong to electric lighting or auto parts and components field.
Background technology
Existing headlight for vehicles structural design utilizes light reflection principle to be made up of light source and parabolic reflector cavity usually, two kinds of branch dipped headlights and high beams, and night is during cruising; Especially exercise night on highway, use be high beam, its light angle is high; Easily the place ahead is reached in the same way driver or pedestrian in opposite directions and cause and dazzle the eyes, and that the illumination angle of dipped headlights is spent is low, illumination zone is little, and in the use; The scattering halation that can have border circular areas blocks and adopts modes such as rear-projection through on emitting bulb, adding, and dazzles the eyes degree to weaken to some extent though make; But still have that light-use is insufficient, the light type is undesirable; Scattered light with soak reverberation and cause light can not concentrate and utilization not yet in effect, energy disperses, and makes situation and the elimination of dazzling the eyes not yet in effect.The car light of the front vehicle of going in the same way night is to the driver and crew's in its place ahead influence, and night is in opposite directions during meeting, even switched to dipped headlights; Also still dazzle the eyes each other; And in the instant that two cars are met, the driver has of short duration losing one's sight at the moment, does not see the place ahead road conditions; Seriously endanger safe traffic, the night traffic accident that causes thus takes place frequently.For this reason; The somebody attempts with passive method, as using infrared viewing device, wear driver's protective glasses, more have it is complicated; As utilize polarized glass lampshade or shade or let modes such as car light electric powered steering, all fail fundamentally to solve effectively the safety problem that dazzling light brings.In addition; Car light causes modern optical to pollute and potential safety hazard; Make and all will plant the flowers and plants of suitable height in the two-way lane isolation strip of highway and add the frequency modulated light plate, also the cement hard shoulder of centre is added highly on the viaduct, city, increased the cost that road infrastructure is built; The driver also must frequently be switched between high beam and dipped headlights etc., complex operation and be prone to produce driving fatigue.
Above-mentioned present situation shows that prior art also fails effectively to solve the glare problem that night, automobile lamp caused.
The utility model content
The utility model first technical problem to be solved is: a kind of headlight for vehicles light distribution structure is provided, is used to solve the glare problem that night, automobile lamp caused.
The utility model second technical problem to be solved is: a kind of LED headlight for vehicles is provided, is used to solve the glare problem that night, automobile lamp caused.
In order to solve first technical problem of the utility model, the utility model is realized through following technical scheme:
A kind of headlight for vehicles light distribution structure; Comprise light shield, led light source, LED lens; It is characterized in that: said light distribution structure also comprises speculum and ligulate speculum, and said ligulate speculum is located at the light shield bottom, and the LED lens cover is at the light-emitting area of led light source and be installed in the speculum; Constitute an integral body, said integral installation is in the inside of said light shield.
15 ° of said speculum deflections, said ligulate speculum is made by reflectorized material.The formed distribution curve flux of said light distribution structure is the narrow luminous intensity distribution type of asymmetric duck ligulate.
In order to solve second technical problem of the utility model; The utility model also provides a kind of LED headlight for vehicles; Said LED headlight for vehicles has a kind of light distribution structure of headlight for vehicles, said light distribution structure comprise light shield, led light source, LED lens, it is characterized in that: said light distribution structure also comprises speculum and ligulate speculum; Said ligulate speculum is located at the light shield bottom; The LED lens cover is at the light-emitting area of led light source and be installed in the speculum, constitutes an integral body, and said integral installation is in the inside of said light shield.
15 ° of said speculum deflections, said ligulate speculum is made by reflectorized material.The formed distribution curve flux of said light distribution structure is the narrow luminous intensity distribution type of asymmetric duck ligulate.
This headlight for vehicles light distribution structure has formed the distribution curve flux of the narrow luminous intensity distribution type of asymmetric duck ligulate; When two cars are met; Benefit from this light distribution structure, the irradiation light intensity of the light that level makes progress is limited at certain limit, can solve the glare problem that night, automobile lamp caused; And receive the effect of ligulate speculum, luminous energy is fully used.The utility model is applicable to various types of LED headlight for vehicles.
