Abstract
The invention discloses a lens for forming a passing light lighting pattern. The lens comprises an LED light source and an outer lens; a light shielding plate is horizontally placed between the LED light source and the lens; the LED light source is positioned above the light shielding plate, and is inclined, so that light emitted by the LED light source is aslant irradiated to the light shielding plate; and the baffle plate is positioned above the bottom of the lens. The lens can realize the passing light lighting pattern through a projecting mode; the transparent plastic lens is put in front of the light source; after light rays emitted by the light source are projected to the lens, the light rays are reflected and refracted to pass through the matched baffle plate and lens to finally form the passing light lighting pattern; the passing light lighting pattern formed by the lens is smooth and clear; the light distribution is uniform; the utilization rate of the light rays is high; the structure is small; and the lens adopts a projection passing light design.
Description
Technical field
The present invention relates to one kind is for automobile headlight low beam design neck, 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, it is desirable to have uniformly steady and audible light type, can both allow driver preferably observe road conditions in direction of traffic, while also can
Enough ensure that the pedestrian on opposite and vehicle sight line are not affected by dipped beam, to play while ensureing driver and opponent vehicle and pedestrian
Safety,
For automobile lamp, as light source uses halogen lamp or Xe lamp bulb, therefore general mode is reflective
Design of Optical System, and reverberation bowl needs holding certain distance with light source, can otherwise be burned out or affect service life, this
Kind space design is limited and brings a lot of inconvenience to car light design, and reverberation bowl volume is larger, and fiber-loss is larger, produces into
This is higher, therefore, solves the problems, such as that this class is particularly important.
Content of the invention
For the deficiencies in 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, and the light part after reflection from lens refraction is cut by light barrier, and a part is kept off
Tabula rasa reflects, and then all of light all can form a complete dipped beam light type through outer lens, 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 with outward
Lens, the light barrier for having horizontal positioned in the middle setting of the LED light source and the lens, the LED light source is located at and is in the light
The top of plate is simultaneously inclined to set so that the irradiation that the light that LED light source sends is inclined is 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 LED, by adjusting the pass of each LED
Close to realize different light type.
Further improvement is that：The lens adopt convex lenss, and the lens are made of plastics.
Further improvement is that：The lens be internally provided with aperture, the light that LED light source sends injects lens by aperture
In, form after reflected refraction being carried out in lens the injection of specific light path.
The invention has the beneficial effects as follows：The present invention passes through to place a light barrier, Jing Guotou between lens and LED light source
The a part of light of light after mirror reflected refraction is cut by light barrier, is projected directly at below lens, shape after the refraction of lens
Become the dipped beam light type with "cut-off"line, a part is reflected by light barrier, the top of lens is then projected, through lens
Also the lower section of "cut-off"line is converged to a long way off after refraction, and two parts light beam is combined into the light type of dipped beam, in the screen of 25M distant place
On curtain, observation is obtained, 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 fits
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 smooth clear, and light distribution is uniform, and
Light utilization height, compact structure.

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 source, 2- lens, 3- light barrier.
Specific embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the present invention is further described, the present embodiment
It is only used for the present invention is explained, does not constitute limiting 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, includes LED light source 1 and thoroughly
Mirror 2, the light barrier 3 for having horizontal positioned in the middle setting of the LED light source 1 and the lens 2, the LED light source 1 is located at gear
The top of tabula rasa 3 is simultaneously inclined to set so that the irradiation that light that LED light source 1 sends is inclined on light barrier 3, the light barrier 3
Top positioned at 1 bottom of lens.The LED light source 1 is combined by least two LED, by adjusting the closing of each LED
To realize different light type.The lens 2 adopt convex lenss.The lens 2 be internally provided with aperture, LED light source sends
Light is injected in lens by aperture, forms light path injection in lens after carrying out reflected refraction.
The present invention passes through to place a light barrier 3 between lens 2 and LED light source 1, the light after reflection from lens refraction
The a part of light of line is cut by light barrier, is projected directly at below lens, is formed with "cut-off"line after the refraction of lens
Dipped beam light type, a part reflected by light barrier, then project the top of lens, also converge 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 obtaining on the screen of 25M distant place, 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 by the way of projection-type, no
Dipped beam light type is only applicable to, is also applied for distance light light type, such as matrix form distance light light type.
