Detailed description of the invention
Fig. 1 is the utility model overall structure diagram；
In figure: 1, driving and observation circuit；2, LED board；3,LED；4, astigmatism plate；5, protection board.
Specific embodiment
Refering to fig. 1, a kind of automatic driving vehicle bottom intelligent lighting light source, the mains lighting supply include needed for providing for LED
Electric current, control LED luminance and detect LED whether driving and observation circuit 1, LED board 2, the LED3, astigmatism of overcurrent and overheat
Plate 4 and protection board 5；The driving and observation circuit 1, LED board 2, astigmatism plate 4 and protection board 5 are installed in a shell knot
In structure, which is fixed on two front-wheel middle positions of vehicle bottom；The driving and observation circuit 1 passes through electric wire
It is connected with LED3；The LED3 is welded on above LED board 2；The astigmatism plate 4 is arranged in front of LED3；The guarantor
Backplate 5 is set below astigmatism plate 4, and rack gear is housed on protection board 5.Motor, the motor are provided in the shell mechanism
It is connected with rack gear.Motor drives rack movement by train of reduction gears, and then protection board 5 is driven to move, and can block guarantor completely
Lighting part is protected, is not being needed in use, not polluted by external condition for protective device.
The driving and 1 one side of observation circuit provides driving current for the LED3 of high brightness, on the other hand also right
The working condition of LED3 is monitored.Driving circuit lights electric current required for LED, driving electricity as the offer of current mode power device
Road has enable end, can control LED luminance by PWM mode.Observation circuit can detecte LED whether overcurrent and mistake
Heat.
Can be there are many LED3 lighting mode, for example it is always on mode and strobe mode, the starting point and duration of stroboscopic can lead to
It crosses control signal or the global standards time is cooperateed with the exposure of camera.
Illuminating LED plate 2 can also play the heat-conducting plate of highlighted LED for carrying LED3 and providing current path
Effect.
The high-brightness LED composition illumination array of multicore can be used in illuminating LED 3, can realize a variety of light by control
The mixing of spectrum individually shines, and the illumination of the object of different colours is preferably provided for camera.It can also be realized by control
Different zones or illumination of different shapes.
Astigmatism plate 4 is used for the light uniformly dispersing of LED array.
Protection board 5 can block completely and protect lighting part, not need in use, for protective device not by outside
Condition pollution.
The utility model lane line can be accurately identified in the insufficient situation of light intensity in intelligent automobile and barrier provides branch
It holds.
