Description
Technical field
The present invention relates to automobile lamp technical field more particularly to a kind of light source assembly based on variable refractivity lens, one
Kind includes the vehicle lamp assembly of the light source assembly and a kind of automobile including the vehicle lamp assembly.
Background technology
According to car light distance light regulation, distance light maximum value (i.e. Emax values) needs in certain brightness range, such as automobile
LED headlamps GB25991 is the vehicle light illumination performance code about LED light source, it is determined that using LED as the headlamp of light source,
Luminous intensity distribution performance requirement including illumination functions such as distance light, dipped beams.Wherein, distance light maximum value (i.e. Emax values) require 48lx extremely
Between 240lx, the 75R test point test values of dipped beam require to be not less than 12lx.
It is a kind of existing instant and near light car light as shown in Figure 1 to reach requirement of the above-mentioned regulation to headlamp luminous intensity distribution performance
Lighting system is made of LED light source 01, speculum 02, barn door 03 and convex lens 04.Wherein, speculum 02 is class ellipsoid,
LED light source 01 is arranged at the perifocus of speculum 02, and the over focus of speculum 02 is arranged in 04 near focal point of convex lens.LED
The light that light source 01 is sent out passes through at the reflecting focal to the over focus of speculum 02 of speculum 02, and barn door 03 is equipped with and dipped beam
The required relevant light shielding part of "cut-off"line shape of illumination, the light shielding part are arranged in 04 focal point of convex lens, finally lead to
It crosses convex lens 04 light for converging in 04 near focal point of convex lens is converted into class directional light and be irradiated to road surface, and formed and shading
Plate 03 ends the relevant lower beam illumination light shape of wire shaped.Far lighting is then realized by removing barn door 03 with certain illumination
The far lighting light shape of maximum value.The method that this realization distance light maximum value and dipped beam 75R test point test values require is by LED
The limitation of 01 characteristics of luminescence of light source (diverging of approximate Lambertian type), the scattering light sent out by LED light source 01 are converged by speculum 02
The larger angle of divergence is equally existed after to the over focus of speculum 02, this larger angle of divergence causes light to reach convex lens
When 04 plane of incidence, radiation luminous intensity weakens significantly, causes finally by the illumination for being converted into class directional light after convex lens 04
Light shape is difficult to realize larger distance light Emax values or dipped beam 75R test point test values, or needs to improve the output of LED light source 01
Luminous flux realizes the distance light Emax values and dipped beam 75R test point test values of laws and regulations requirement, but improves the output light of LED light source 01
Flux can bring the raising of the heat-sinking capability of the cooling system to radiate to LED light source 01, because improving the defeated of LED light source 01
Enter the problem of output power of the Voltage stabilizing module of power rise and LED light source 01 caused by electric current increases, it is often more important that
It is limited by the luminous power of LED light source 01, the output light flux of LED light source 01 also has limiting value, cannot infinitely improve.This
In the case of, it generally requires to realize distance light or lower beam illumination function jointly even more than lighting system by two, leads to structure
The problems such as complicated, weight and cost increase.
In addition, GB25991 equally requires, light is with larger the photochromic of automobile LED headlamps, i.e. chromatic value
When angle of scattering injects the plane of incidence of convex lens 04, it is also easy to produce dispersion after the refraction twice of 04 plane of incidence of planoconvex lens and light-emitting surface,
Also it is not easy to meet the requirement of regulation.
