Abstract
The utility model relates to an LED (light-emitting diode) projection 8-point light distribution reflection mechanism for an automobile headlight, which comprises an LED lamp, a reflector, an integrated circuit board, a radiator and a lens, wherein the reflector is arranged above the LED lamp; the integrated circuit board and the radiator are arranged under the LED lamp; the lens is arranged at the front end of the LED lamp; a bezel is arranged between the LED lamp and the lens; and a small reflector capable of receiving light rays of reflector is arranged at the top of the bezel. By the reflected light rays, weak light can be provided for a dark zone above a cutoff line and 8-point light distribution required by an automobile lamp passing light regulation is realized.
Description
Technical field
The utility model shines dipped headlights before relating to a kind of LED, belongs to the automobile lamp field.
Background technology
Existing LED projection car headlamp; Light forms "cut-off"line through speculum, shadow shield, lens imaging and obtains light and shade district light shape; Being that "cut-off"line is above is the dark space to be the clear zone below the "cut-off"line, but the brightness value of car light dipped beam laws and regulations requirement in 2007 dark space can not be zero; The illumination of dark space should be 8 illumination light shapes; According to the principle of LED projection headlamp, existing LED projection car headlamp product illumination performance also imperfection and statutory standard also has distance, so proposed the problem of an invention to people.
The utility model content
The purpose of the utility model provides 8 luminous intensity distribution reflecting mechanisms of a kind of LED projection car headlamp, through the reflection ray of this mechanism, can the low light level be provided to the dark space more than the "cut-off"line, realizes 8 luminous intensity distributions of car light dipped beam laws and regulations requirement.
The technical scheme of the utility model is: 8 luminous intensity distribution reflecting mechanisms of a kind of LED projection car headlamp; Comprise the LED lamp, be contained in LED lamp top speculum, be contained in surface-mounted integrated circuit and radiator below the LED lamp; Be contained in the lens of LED lamp front end; Be provided with shadow shield between LED lamp and lens, it is characterized in that: the small reflector that can receive speculum light is equipped with at the shadow shield top.
Present technique can with the part light of LED lamp through mirror reflects to small reflector, reflex to the above dark space of "cut-off"line again, realized 8 luminous intensity distributions of laws and regulations requirement, it is simple in structure, light distribution effect is good.
Description of drawings
Fig. 1 is the structural representation of 8 luminous intensity distribution reflecting mechanisms of the utility model LED projection car headlamp.
Fig. 2 is the result of use figure of 8 luminous intensity distribution reflecting mechanisms of LED projection car headlamp.
1 speculum, 2 supports, 3 small reflectors, 4 shadow shields, 5LED lamp, 6 surface-mounted integrated circuits, 7 radiators, 8 small reflector supports, 9 shadow shield supports, 10 lens, 11 "cut-off"lines, 12 dark spaces, 13 clear zones among the figure.
The specific embodiment
8 luminous intensity distribution reflecting mechanisms of LED projection car headlamp; Comprise LED lamp 5, be contained in LED lamp top speculum 1, be contained in surface-mounted integrated circuit 6 and radiator 7 below the LED lamp, LED lamp front end is connected with lens 10 through support 2, is provided with shadow shield 4 between LED lamp and lens; Shadow shield is supported by shadow shield support 9; The characteristics of present technique are, at shadow shield one side roof part small reflector 3 are housed, and small reflector 3 has design point of view with speculum 1; Can receive speculum light, small reflector is supported by small reflector support 8.LED light is through speculum 1, formed "cut-off"line 11 through the imaging of shadow shield 4; Penetrate through lens; "cut-off"line is dark space 12 more than 11; "cut-off"line is clear zone 13 below 11, and LED lamp part light shines the dark space 12 more than the "cut-off"line through small reflector 3, has realized 8 luminous intensity distributions of laws and regulations requirement.
