Vehicle headlamps realizes that independent function all has solitary lamps and lanterns or module to realize, this just makes and has contained a plurality of lamps and lanterns or module among the vehicle headlamps, and installation back lighting lantern festival takies very big place. The utility model discloses the constitution includes: blue laser (1), green laser (2), red laser (3), it is first double -colored to optical filtering (4), the second is double -colored to optical filtering (5), DMD subassembly (6), reflector (7), lens (8), it is first double -colored to the optical filtering, the second is double -colored to the optical filtering, blue laser and reflector are all on same horizontal plane, green laser sets up under first double -colored optical filtering, red laser sets up under the double -colored optical filtering of second, the DMD subassembly is first double -colored to the optical filtering with the plane perpendicular to at lens place, the second is double -colored to the optical filtering, the horizontal plane that blue laser and reflector were located. The utility model is used for automotive lighting.
Description
Technical field:
This utility model relates to a kind of automobile DMD laser headlamp.
Background technology:
The parts that headlamp must be equipped with as automobile, in fullness in the epigastrium and abdomen foot driver's demand to illumination of driving a vehicle, car headlamp has the functions such as distance light, dipped beam, meeting delustring, AFS at present, and realize these functions, having a single light fixture or module to realize, this allows for containing multiple light fixture or module in car headlamp, and installation back lighting lantern festival takies side greatly, the space of miscellaneous part in automobile can be compressed, the overall dimensions of automobile can have been limited.
Utility model content:
The purpose of this utility model is to provide a kind of automobile DMD laser headlamp.
Above-mentioned purpose is realized by following technical scheme:
A kind of automobile DMD laser headlamp, its composition includes: blue laser, green (light) laser, red laser, first dichroic filters, second dichroic filters, DMD assembly, illuminator, lens, the first described dichroic filters, the second described dichroic filters, described blue laser and described illuminator are in same level, described green (light) laser is arranged on immediately below the first described dichroic filter, described red laser is arranged on the underface of the second described dichroic filter, described DMD assembly is perpendicular to the first described dichroic filters with the plane at described lens place, the second described dichroic filters, horizontal plane residing for described blue laser and described illuminator.
Described automobile DMD laser headlamp, it is 615 ~ 620nm that described red laser sends the wavelength of light, it is 530 ~ 540nm that described green (light) laser sends the wavelength of light, the wavelength that described blue laser sends is 460 ~ 470nm, and it is 3:6:1 that described red laser, described green (light) laser, described blue laser send the strength ratio of light；Described first is double-colored to filter reflection green glow, other wavelength light of transmission, and described second is double-colored to filter reflection HONGGUANG, other wavelength light of transmission；Described DMD assembly is provided with dmd chip and control circuit plate.
Beneficial effect:
Blue laser horizontal positioned the most of the present utility model, blue laser level penetrates；Green laser and red laser are disposed vertically, and green is vertical with red laser to be penetrated；nullFirst dichroic filters and the second dichroic filters are individually positioned in blue laser and the intersection of green red laser and place in 45° angle，Such design makes trichroism laser all irradiate on a mirror after transmission or reflection，Wherein first blue laser is radiated at double first color on filter lens，Because the first dichroic filters is only to green reflection，So blue laser is transmitted through the first dichroic filters，It is radiated on the second dichroic filters，Second dichroic filters is to reflection to red light，Other light transmissions，Therefore blue laser is transmitted through the second dichroic filters，It is radiated on illuminator，Green laser is first radiated on the first dichroic filters，Owing to the first dichroic filters is to green reflection，Green laser is through reflection，It is radiated on the second dichroic filters，Second dichroic filters is to reflection to red light，So green light transmission crosses the second dichroic filters，It is radiated on illuminator，After red laser injection，Impinge upon on the second dichroic filters，Second dichroic filters is to reflection to red light，So red laser is after reflection，It is irradiated on illuminator，So，Trichroism laser overlaps，Red、Green、Blue trichroism laser intensity ratio is for 3:6:1，Synthesis white light，White light is after mirror reflection，It is irradiated on DMD assembly.DMD assembly is by its internal control circuit plate, form the image required for dim head lights and distance light and AFS automotive self-adaptive headlight system, the white light reflection being emitted onto on DMD assembly is gone out, through lens, the light type of needs is irradiated to a distant place, reach the light distribution requirements of car light, it is also possible to realize the function of delustring when meeting by controlling DMD assembly.
This utility model uses the image function that DMD is powerful, achieve a lamp multi-functional, the functions 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, so having saved substantial amounts of space and weight.
Accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present utility model.
