Description
Technical field
The present invention relates to lighting area, it is specifically related to a kind of with dead line and meet the illumination group of dipped beam regulation
Part.
Background technique
Motorcycle, electric vehicle dipped headlight light distribution should make dipped beam have it is enough illumination and it is dazzle-free.Such as.Such as
For motorcycle dipped headlight, light distribution requires to need to determine based on the following:
(1) there are enough road illuminations and irradiating width, the uniformity of road lighting guarantees enough visibilities；
The enough brightness in road surface is provided, the projection width of light is sufficiently large；Safety is provided for driver；
(2) dazzle of the vehicle driver to come head-on is limited；
(3) irradiation position of lamps and lanterns light beam and light intensity performance；
(4) certain diverging light and forward position light are provided for the comfort level of driver.
Therefore, in order to meet the requirement of car light, low beam light source allows for getting "cut-off"line.Existing low beam light source
So that dipped beam LED is got "cut-off"line using the combination light distribution of reflector and lens, but its lens it is generally circular in cross section,
Then oval or rectangular plano-convex lens form light and shade cut-off to play the effect of optically focused by the reflective design of reflector again
Line, but since aggregation extent of the reflector to light is not good enough, so that the strip light spots of the "cut-off"line formed are not clear enough
It is clear, that is to say, that the effect of "cut-off"line is not obvious enough.
