Abstract
The invention discloses an automobile headlamp grading structure and a light-emitting diode (LED) automobile headlamp using the structure. The automobile headlamp grading structure comprises a lens hood, an LED light source and an LED lens, and the automobile headlamp grading structure is characterized by further comprising a reflector and a tongue-shaped reflector, the tongue-shaped reflector is arranged on the lower portion of the lens hood, the LED lens is covered on a lighting surface of the LED light source and installed in the reflector, a whole is formed, and the whole is installed in the lens hood. The automobile headlamp grading structure forms a duck tongue-shaped distribution curve flux, irradiating light intensity of upwards horizontal light is limited in a certain scope when two automobiles meets due to the grading structure, glare problems caused by automobile lamps at night can be solved, and the light can be sufficiently used due to reflection effects of the tongue-shaped reflector. The automobile headlamp grading structure can be applicable to various automobile headlamps.
Description
Technical field
The present invention relates to a kind of headlight for vehicles light distribution structure and use the LED headlight for vehicles of this structural design, irradiation height with effective control automobile lamp light in normally travelling, reduce light pollution, avoid light that opposite driver or pedestrian are dazzle the eyes, belong to electric lighting or auto parts and components fields.
Background technology
existing headlight for vehicles structural design utilizes light reflection principle usually to be comprised of light source and parabolic reflector cavity, divide two kinds of dipped headlights and high beams, night is when normally travelling, especially exercise on highway night, what use is high beam, its light angle is high, the driver or the pedestrian that easily the place ahead are reached in the same way in opposite directions cause and dazzle the eyes, and the light angle of dipped headlights is too low, illumination zone is little, and in use procedure, can there be the scattering halation of border circular areas, block and adopt the modes such as rear-projection by adding on emitting bulb, dazzle the eyes degree to weaken to some extent although make, but still exist light-use insufficient, the light type is undesirable, scattered light and soak reverberation and cause light can not concentrate and utilization not yet in effect, energy disperses, make situation and the elimination not yet in effect dazzle the eyes.The impact of the car light of the front vehicle of travelling in the same way night on the driver and crew in its place ahead, 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 blind at the moment, does not see the place ahead road conditions, seriously endanger safe traffic, the night traffic Frequent Accidents that causes thus.For this reason, the somebody attempts with passive method, as using infrared viewing device, wear protection glasses for driver, more have it is complicated, as the mode such as utilize polarized glass lampshade or shade or allow that vehicle-lamp electric turns to, all fail fundamentally effectively to solve the safety problem that dazzling light brings.In addition, car light causes modern optical to pollute and potential safety hazard, make the flowers and plants that all will plant suitable height in the two-way lane isolation strip of highway and add the frequency modulated light plate, also add the cement separation mound of centre high 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 easily produce driving fatigue.
Above-mentioned present situation shows, prior art also could not effectively solve the glare problem that night, automobile lamp caused.
Summary of the invention
First technical problem to be solved by this invention is: a kind of headlight for vehicles light distribution structure is provided, is used for solving the glare problem that night, automobile lamp caused.
Second technical problem to be solved by this invention is: a kind of LED headlight for vehicles is provided, is used for solving the glare problem that night, automobile lamp caused.
In order to solve first technical problem of the present invention, the present invention is achieved by the following technical solutions:
A kind of headlight for vehicles light distribution structure, comprise light shield, LED light source, LED lens, it is characterized in that: described light distribution structure also comprises speculum and ligulate speculum, described 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 arranged in speculum, consist of an integral body, described integral installation is in the inside of described light shield.
15 ° of described speculum deflections, described ligulate speculum is made by reflectorized material.The formed distribution curve flux of described light distribution structure is the duck ligulate.
In order to solve second technical problem of the present invention, the present invention also provides a kind of LED headlight for vehicles, described LED headlight for vehicles has a kind of light distribution structure of headlight for vehicles, described light distribution structure comprise light shield, LED light source, LED lens, it is characterized in that: described light distribution structure also comprises speculum and ligulate speculum, described 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 arranged in speculum, consist of an integral body, described integral installation is in the inside of described light shield.
15 ° of described mirror reflects mirror deflections, described ligulate speculum is made by reflectorized material.The formed distribution curve flux of described light distribution structure is the duck ligulate.
This headlight for vehicles light distribution structure has formed the distribution curve flux of 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 be subject to the effect of ligulate speculum, luminous energy is fully used.The present invention is applicable to various types of LED headlight for vehicles.

The specific embodiment
Below in conjunction with Figure of description, the present invention is described in further detail.
Referring to Fig. 1, Fig. 2 and shown in Figure 3, a kind of headlight for vehicles light distribution structure, by light shield 1, LED light source 3, LED lens 4, speculum 2 and ligulate speculum 5 form, ligulate speculum 5 is located at light shield 1 bottom, and Figure 11 and LED lens 4 shown in Figure 12 cover at the light-emitting area of LED light source 3 and are arranged in speculum 2, consist of an integral body, described integral installation is in described light shield 1, and the structure of light shield 1 is referring to Fig. 4, Fig. 5 and shown in Figure 6.Open Side Down tilts 40 ° for speculum 2, and ligulate speculum 5 is made by reflectorized material, and its structure is referring to Fig. 7, Fig. 8, Fig. 9 and shown in Figure 10.This light distribution structure can form Figure 13 or duck ligulate distribution curve flux shown in Figure 14.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 is subject to the reflex of ligulate speculum 5, and luminous energy is fully used.
