Description
Technical field:
The present invention relates to a kind of use DMD with infrared function headlight of car and means of illumination.
Background technology:
Current car headlamp has the functions such as distance light, dipped beam, meeting delustring, AFS, and realizes these functions, has an independent light fixture or module to realize, and headlamp just contains multiple light fixture or module.
Summary of the invention:
It is an object of the invention to provide a kind of use DMD with infrared function headlight of car and means of illumination.
Above-mentioned purpose is realized by following technical scheme:
A kind of use DMD with infrared function headlight of car, its composition includes: white light LEDs, described white light LEDs front is to there being dichroic filters, described dichroic filters front has integrating rod assembly, below described dichroic filters, there is infrared LED, described integrating rod assembly front has illuminator, and the left oblique upper of described illuminator has DMD assembly, has lens below described DMD assembly.
The described means of illumination with infrared function headlight of car using DMD, first white light LEDs horizontal positioned, infrared LED is perpendicular to white light LEDs and places, dichroic filters is placed by the two light intersection, it is 45�� angle in light, integrating rod assembly is placed in light path front, illuminator is placed after integrating rod, condition is used to adjust illuminator angle by DMD, light is made to use condition to incide DMD reflecting surface by DMD, just DMD is placed lens, the light transmission dichroic filters that white light LEDs sends, by integrating rod assembly, irradiate on a mirror, white light is reflexed to DMD, lens are by DMD image transmission to front side, form required distance-light, the function of meeting and AFS, when needs infrared light supply, infrared LED is lighted, Infrared is reflected by dichroic filters, inject integrating rod, through integrating rod, by mirror reflection to DMD, reflected by DMD, it is mapped to a distant place by lens, infrared light supply is provided.
Beneficial effects of the present invention:
1. the present invention uses the image function that DMD is powerful, it is achieved that a lamp is multi-functional, and the function such as distance light, dipped beam, AFS, meeting delustring can be realized by this lamp.
The function of traditional several lamps is synthesized in a lamp by the present invention, so having saved substantial amounts of space and weight.
The present invention provides infrared light supply, it is possible to coordinate other sensors, it is achieved the functions such as infrared night vision.
White light LEDs horizontal positioned of the present invention, infrared LED is perpendicular to white light LEDs and places, and dichroic filters is placed by the two light intersection, is 45�� angle in light. Integrating rod assembly is placed in light path front, places illuminator after integrating rod, uses condition to adjust illuminator angle by DMD, makes light use condition to incide DMD reflecting surface by DMD. Just DMD is placed lens.
Accompanying drawing illustrates:
Accompanying drawing 1 is the structural representation of the present invention.
Detailed description of the invention:
Embodiment 1:
A kind of use DMD with infrared function headlight of car, its composition includes: white light LEDs 1, described white light LEDs front is to there being dichroic filters 3, described dichroic filters front has integrating rod assembly 4, there is below described dichroic filters infrared LED 2, described integrating rod assembly front has illuminator 6, and the left oblique upper of described illuminator has DMD assembly 5, has lens 7 below described DMD assembly.
Embodiment 2:
The means of illumination with infrared function headlight of car using DMD according to embodiment 1 or 2, first white light LEDs horizontal positioned, infrared LED is perpendicular to white light LEDs and places, dichroic filters is placed by the two light intersection, it is 45�� angle in light, integrating rod assembly is placed in light path front, illuminator is placed after integrating rod, condition is used to adjust illuminator angle by DMD, light is made to use condition to incide DMD reflecting surface by DMD, just DMD is placed lens, the light transmission dichroic filters that white light LEDs sends, by integrating rod assembly, irradiate on a mirror, white light is reflexed to DMD, lens are by DMD image transmission to front side, form required distance-light, the function of meeting and AFS, when needs infrared light supply, infrared LED is lighted, Infrared is reflected by dichroic filters, inject integrating rod, through integrating rod, by mirror reflection to DMD, reflected by DMD, it is mapped to a distant place by lens, infrared light supply is provided.
Embodiment 3:
The means of illumination with infrared function headlight of car using DMD according to embodiment 1 or 2, white light LEDs horizontal positioned, the lens being mated, the light that LED sends are placed in LED light-emitting area front, after lens, pool nearly directional light. After light is irradiated to dichroic filters, because the saturating visible ray of dichroic filters, anti-infrared, so, after the light that white light LEDs sends arrives dichroic filters, direct transmissive, it is irradiated to integrating rod assembly. Integrating rod assembly has the effect of all light, and white light passes through integrating rod, through mirror reflection, is irradiated on DMD. DMD passes through control circuit, form dim head lights and distance light and AFS(AdaptiveFront-LightingSystem) image of light type required for automotive self-adaptive headlight system, the white light reflection being emitted onto DMD is gone out, through lens, the light type of needs is irradiated to a distant place, reaches the light distribution requirements of car light. Can also realize when meeting, the function of delustring. When needs infrared light supply time, infrared LED is lit, and infrared LED is perpendicular to white light LEDs and places, and infrared light exports nearly directional light through the lens being mated, reflected through dichroic filters, by integrating rod assembly, then through mirror reflection, it is irradiated on DMD, reflect through DMD, by lens, it is transmitted to a distant place, it is achieved the function of infrared light supply.
