Abstract
The utility model discloses a kind of lens for forming dipped beam light type, include LED/light source and outer lens, the centre of the LED/light source and the lens is provided with the light barrier of horizontal positioned, the LED/light source is located at the top of light barrier and is inclined to set, it is radiated at so that the light that sends of LED/light source is inclined on light barrier, the baffle plate is located at the top of lens bottom, the utility model can realize the light type of dipped beam with the mode of projection-type, a transparent plastic lens is placed in front of light source, the light that light source is sent is projected after lens, baffle plate and lens that can be through overmatching after its reflected refraction, eventually form dipped beam light type, the dipped beam light type of such a lens forming is smoothly clear, light distribution is uniform, and light utilization is high, compact structure, it is a kind of very useful new projection-type dipped beam design.
Description
Technical field
Design and lead for automobile headlight low beam the present invention relates to one kind, more particularly to one kind can form clear uniform
Dipped beam light type lens.
Background technology
In the general headlamp regulation in the world, all there are clear and definite light distribution requirements to dipped beam, meet the dipped beam light of regulation
Type can both allow driver preferably to observe road conditions in direction of traffic, while also can, it is necessary to there is uniform steady and audible light type
Enough ensure that the pedestrian on opposite and vehicle sight line are not influenceed by dipped beam, to play while ensureing driver and opponent vehicle and pedestrian
Safety, for automobile lamp, because light source uses halogen bulb or Xe lamp bulb, therefore general mode is reflective
Optical System Design, and reverberation bowl needs holding certain distance with light source, otherwise can be burned out or influence service life, this
Kind space design is limited brings many inconvenience to car light design, and reverberation bowl volume is larger, and fiber-loss is larger, is produced into
This is higher, and therefore, the problem of solving this class is particularly important.
The content of the invention
In view of the shortcomings of the prior art, the invention provides a kind of lens for forming dipped beam light type, by lens and LED
A light barrier is placed between light source, the light part after reflection from lens is reflected is cut by light barrier, and a part is kept off
Tabula rasa reflects, and then all light all can be by outer lens one complete dipped beam light type of formation, to solve existing Automobile
The limitation of lamp.
In order to solve the above problems, the invention provides a kind of lens for forming dipped beam light type, include LED/light source and outer
Lens, the light barrier of horizontal positioned is provided with the centre of the LED/light source and the lens, and the LED/light source, which is located at, to be in the light
The top of plate is simultaneously inclined to set so that light that LED/light source is sent is inclined to be radiated on light barrier, and the baffle plate is located at lens
The top of bottom.
Further improvement is that：The LED/light source is combined by least two LEDs, by the pass for adjusting each LED
Close to realize different light type.
Further improvement is that：The lens use convex lens, and the lens are made of plastics.
Further improvement is that：The lens are internally provided with aperture, and the light that LED/light source is sent injects lens by aperture
In, carry out forming specific light path injection after reflected refraction in lens.
The beneficial effects of the invention are as follows：The present invention between lens and LED/light source by placing a light barrier, by saturating
A part of light of light after mirror reflected refraction is cut by light barrier, is projected directly at below lens, the shape after the refraction of lens
Into the dipped beam light type with "cut-off"line, a part is reflected by light barrier, the top of lens is then projected, by lens
Also the lower section of "cut-off"line is converged to after refraction a long way off, two parts light beam is combined into the light type of dipped beam, the screen in 25M distant places
Observation is obtained on curtain, and cut light beam occupies more than the 85-90% of total light beam, and the present invention is applicable not only to dipped beam light type, also fitted
For distance light light type, such as matrix form distance light light type, the dipped beam light type of lens forming of the present invention is smoothly clear, and light distribution is uniform, and
Light utilization is high, compact structure.
Brief description of the drawings
Fig. 1 is the principle assumption diagram of the present invention.
Fig. 2 is the front view of the lens of the present invention.
Fig. 3 is the rearview of the lens of the present invention.
Wherein：1-LED light sources, 2- lens, 3- light barriers.
Embodiment
In order to deepen the understanding of the present invention, the present invention is further described below in conjunction with embodiment, the present embodiment
It is only used for explaining the present invention, is not intended to limit the scope of the present invention..
As shown in Figure 1, 2, 3, a kind of lens for forming dipped beam light type are present embodiments provided, include LED/light source 1 and saturating
Mirror 2, the light barrier 3 of horizontal positioned is provided with the centre of the LED/light source 1 and the lens 2, and the LED/light source 1 is located at gear
The top of tabula rasa 3 is simultaneously inclined to set so that light that LED/light source 1 is sent is inclined to be radiated on light barrier 3, the light barrier 3
Top positioned at the bottom of lens 2.The LED/light source 1 is combined by least two LEDs, by the closing for adjusting each LED
To realize different light type.The lens 2 use convex lens.The lens 2 are internally provided with aperture, what LED/light source was sent
Light is injected in lens by aperture, carries out forming light path injection after reflected refraction in lens.
The present invention between lens 2 and LED/light source 1 by placing a light barrier 3, the light after reflection from lens is reflected
A part of light of line is cut by light barrier, is projected directly at below lens, and being formed after the refraction of lens has "cut-off"line
Dipped beam light type, a part reflected by light barrier, then project the top of lens, also converged a long way off after the refraction of lens
Gather the lower section of "cut-off"line, two parts light beam is combined into the light type of dipped beam, observe and obtain on the screen of 25M distant places, quilt
The light beam of cutting occupies more than the 85-90% of total light beam, and the present invention can realize the light type of dipped beam with the mode of projection-type, no
Dipped beam light type is only applicable to, distance light light type, such as matrix form distance light light type is also applied for.
