Abstract
The utility model relates to an LED moveable automobile headlamp, comprising LED light sources, a reflector and lenses, wherein the lenses and the reflector are connected to form a reflection and refraction system, the reflector is of an ellipsoid, the LED light source is positioned on a focus of the ellipsoid, a second focus of the ellipsoid is superposed with a focus of the lenses, the reflector is fixed with an optical reflector, and the surface of the optical reflector is plated with aluminum and arranged horizontally; the LED light sources are connected on an electric motor through a shaft, and can be rotated at an angle round a shaft; and the electric motor is connected with a power source through conducting wires. The automobile headlamp has the advantages of small light source volume and convenient switch between far beam and dipped beam.
Description
Technical field
The utility model relates to a kind of LED active type car headlamp, belongs to the car light field.
Background technology
The led light source security reliability is strong, can accurately control light type and lighting angle, and is photochromic soft, and free from glare is not mercurous, the material of possibility such as sodium element health risk.What traditional car headlamp adopted is incandescent lamp, and Halogen lamp LED, discharge lamp etc. are as light source, and when lighting, the temperature in the lamp chamber is very high, approximately to 130 ℃～160 ℃, be not easy to the layout and the design of various device, and power consumption is also bigger.The led light source caloric value is low, non-thermal radiation, and cold light source, and also the LED component size is very little, is convenient to the layout and the design of various device more.But existing led light source car headlamp exists instant and near light switches inconvenient shortcoming.
Summary of the invention
It is little that the purpose of this utility model provides a kind of light source volume, the LED active type car headlamp of distance light, dipped beam easy switching.
The technical scheme that realizes above-mentioned purpose is: a kind of LED active type car headlamp, comprise led light source, speculum and lens, after linking to each other with speculum, lens forms the reflected refraction system, speculum is an ellipsoid, led light source is located at a focus place of this ellipsoid, and second focus of ellipsoid overlaps with the focus of lens, is installed with an optical mirror in the speculum, aluminize in this optical mirror surface, and horizontal positioned; Led light source also is connected on the motor by axle, and the led light source angle of can swaying, and motor is connected with power supply by lead.
After adopting technique scheme, when the needs distance light, LED vertically places, and light is through speculum, and optical mirror and the reflected refraction of lens set of lenses can be met the distance light light type of national requirements GB4599.When the needs dipped beam, clockwise rotate LED, make optical mirror just can all reflect all light, light can be met the dipped beam light type of national requirements GB4599 through reflection after the refraction.Thereby distance light, dipped beam switch very convenient.Simultaneously, be led light source owing to what adopt, thereby it is little to have kept the light source volume, is convenient to the layout of various device and the advantage of design.
Description of drawings
Fig. 1 is the structural representation of the utility model under high-beam condition;
Fig. 2 is the structural representation of the utility model under the dipped beam state;
Fig. 3 is circuit theory diagrams of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Shown in Fig. 1～3, a kind of LED active type car headlamp, comprise led light source 4, speculum 2 and lens 1, form the reflected refraction system after lens 1 links to each other with speculum 2, speculum 2 is ellipsoids, and led light source 4 is positioned at a focus place of this ellipsoid, second focus of ellipsoid overlaps with the focus of lens 1, be installed with an optical mirror 3 in the speculum 2, aluminize in these optical mirror 3 surfaces, and horizontal positioned; Led light source 4 also is connected on the motor 6 by axle 5, and led light source 4 can be around axle 5 rotational angles, and motor 6 is connected with power supply by lead.
Operation principle of the present utility model is as follows:
When the needs distance light, led light source 4 is vertically placed, and through speculum 2, optical mirror 3 and lens 1 set of lenses reflected refraction can be met the distance light light type (as shown in Figure 1) of national requirements GB4599.When the needs dipped beam, drive axle 5 by motor 6 and rotate, axle 5 drives led light source 4 and clockwise rotates around axle, makes optical mirror 3 just can all reflect all light, light can be met the dipped beam light type (as shown in Figure 2) of national requirements GB4599 through reflection after the refraction.
