Description
Technical field
The utility model relates to LED fields, and in particular to a kind of LED automobile dipped beam lamp system.
Background technique
LED is as cleaning, environmental protection, energy-efficient forth generation light source, and with manufacturing technology also mature, application is more and more wider
It is general, in recent years, being even more to enter lighting area.
LED light source is compared to for conventional light source, and with the obvious advantage: (1) LED luminous efficiency is high, can convert more electric energy
For luminous energy；(2) LED is small in size, is easy to design product that is compact-sized, occupying little space；(3) service life of LED is long, people
Without frequently replacing light source；(4) response of LED is fast, and the semiconductor light source response time is in nanoseconds magnitude.
The comfort and traffic safety and car headlamp of vehicle driver's nighttime driving are closely bound up.There is research to indicate,
In all traffic accidents of generation, night traffic accident occupies the high proportion close to 50%, therefore auto lamp is that automobile is non-
Often important component part.Automobile dipped headlight is the lamps and lanterns when vehicle when advancing at night, for short distance illumination.According to GB
Requirement of the 25991-2010 automobile LED headlamp national standard to car headlamp, to illuminance, luminous flux and light distribution
There is very high requirement, there is apparent dead line in specified section.And in practical application, light distribution needs to meet country
Standard, it is necessary to have clear cut-off line, light efficiency requires as high as possible.It is clear must to there is light and shade in the maximum section of intensity of illumination
Line of demarcation, if the optical texture with imaging projection, diaphragm is needs certainly, and the appearance of diaphragm, light efficiency will necessarily drop
It is low.The light efficiency of LED low-beam light at present, substantially 50% or so.
Utility model content
In order to overcome shortcoming and deficiency of the existing technology, the utility model provides a kind of LED automobile dipped beam lamp system.
The utility model adopts the following technical solution:
A kind of LED automobile dipped beam lamp system, including three lamp set units, three lamp set unit structures are identical, wrap
Elliposoidal reflector, LED lamp source, substrate, barn door and lens are included, the LED lamp source is disposed on the substrate, and is located at elliposoidal
In the focus of reflector, the spheroid shape reflector and substrate form one with snap-fastener connection type, and the barn door is mounted on
On substrate, and it is higher than substrate, lens are arranged in the front of the reflective cover opening of elliposoidal.
The normal of the LED light source and the angle 43-49 degree of optical axis.
The shading plate shape be it is trapezoidal, the trapezoidal upper left corner be 165 degree.
The barn door is higher than substrate 5mm.
The lens are spherical lens.
Three lamp set units are that "-" type arranges or isosceles triangle arranges.
Distance 20mm of the barn door apart from LED light source.
Lens setting is immediately ahead of the reflective cover opening of elliposoidal at 38.5mm.
The utility model has the beneficial effects that
(1) reflector structure of the utility model is simple, is revolution ellipsoid, easy to process；
(2) simple spherical lens is used, light beam is assigned to the illumination region of needs；
(3) small in size, general construction size is 15.9cm*5.3cm, saves space, facilitates the installation of other devices；
(4) in such a way that three lamp set units combine, the hot stack effect of light source is efficiently avoided；
(5) barn door is equipped with inclined high reflection plane in light source side, and plane is so that reflection light converges in former light
Source position, inclination is the equivalent generation of light convergent point in the position of light source partial below, so that this some light passes through ellipsoid
Lighting area is reached by barn door completely after reflective surface.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is that each lamp set unit light source of the utility model places schematic diagram；
Fig. 3 is the structural schematic diagram of each lamp set unit of the utility model.
Specific embodiment
Below with reference to examples and drawings, the utility model is described in further detail, but the reality of the utility model
It is without being limited thereto to apply mode.
Embodiment
As shown in Figure 1-Figure 3, a kind of LED automobile dipped beam lamp system, including three lamp set units, three lamp set units
