Abstract
The utility model relates to an automobile headlamp with a prism, comprising an LED light source, a shell and lenses. The lenses, a total reflection fixed prism and a total reflection moveable prism form a reflection and refraction system. The automobile headlamp also comprises the total reflection fixed prism and the total reflection moveable prism, wherein the total reflection fixed prism and the total reflection moveable prism are arranged on the same ellipsoid of the shell; the LED light source is fixed on a focus of the ellipsoid; a second focus of the ellipsoid is superposed with a focus of the lenses; the total reflection fixed prism is fixed with the shell, can be rotationally supported on the shell, and is connected with an electric motor through 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 a controllable luminous direction, the conversion between far beam and dipped beam can be conveniently realized through two total reflection prisms.
Description
Technical field
The utility model relates to a kind of car headlamp with prism, belongs to the car light field.
Background technology
What traditional car headlamp adopted is incandescent lamp, and Halogen lamp LED, discharge lamp etc. are as light source, and the shortcoming of this headlamp is that the light source volume is big, 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.LED can accurately control light type and lighting angle, free from glare.Traditional headlamp light source generally all needs a speculum, and technological requirement is than higher, and complicated, has used LED that lighting angle can control as light source, and the effect of speculum has been subdued, and particularly instant and near light switches inconvenient.
Summary of the invention
It is little that the purpose of this utility model provides a kind of light source volume, the car headlamp of the band prism of distance light, dipped beam easy switching.
The technical scheme that realizes above-mentioned purpose is: a kind of car headlamp with prism, comprise led light source, housing and lens, lens and total reflection fixed prism, movable prism is formed the reflected refraction system, also comprise total reflection fixed prism and total reflection activity prism, total reflection fixed prism and total reflection activity prism are positioned on the same ellipsoid of housing, led light source is fixed on the focus of this ellipsoid, and second focus of this ellipsoid overlaps with the focus of lens, the total reflection fixed prism is fixedlyed connected with housing, total reflection activity prism can be rotated to support on the housing, and total reflection activity prism is connected with a motor by axle, and motor is connected with power supply by lead.
After adopting technique scheme, the LED component size is very little, is convenient to the layout and the design of various device more, simultaneously, led light source light type, light emission direction can be controlled.Fully reflecting surface at total reflection prism is aluminized, and when the right angle of total reflection activity prism is in center line, owing to the total reflection effect, can be met the distance light light type of standard GB 4599; When total reflection activity prism by electric system counterclockwise during 90 ° of upsets, total reflection activity prism is equivalent to a baffle plate, by the total reflection of total reflection fixed prism, can be met the dipped beam light type of standard GB 4599.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 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.
As Fig. 1, shown in 2, a kind of car headlamp with prism, comprise led light source 4, housing 2 and lens 1, lens 1 and total reflection fixed prism 3, movable prism 5 is formed the reflected refraction system, also comprise total reflection fixed prism 3 and total reflection activity prism 5, total reflection fixed prism 3 and total reflection activity prism 5 are positioned on the same ellipsoid 8 of housing 2, led light source 4 is fixed on the focus of this ellipsoid 8, and second focus of this ellipsoid 8 overlaps with the focus of lens 1, total reflection fixed prism 3 is fixedlyed connected with housing 2, total reflection activity prism 5 can be rotated to support on the housing 2, and total reflection activity prism 5 is connected with a motor 7 by axle 6, and motor 7 is connected with power supply by lead.
Operation principle of the present utility model is as follows:
Fully reflecting surface at total reflection fixed prism 3 and total reflection activity prism 5 is aluminized, and when the right angle of prism total reflection fixed prism 3 and total reflection activity prism 5 is in center line, owing to the total reflection effect, can be met the distance light light type of standard GB 4599; When total reflection activity prism 5 by electric system counterclockwise during 90 ° of upsets, total reflection activity prism 5 is equivalent to a baffle plate, by 3 total reflections of total reflection fixed prism, can be met the dipped beam light type of standard GB 4599.
