Number of patent application a kind of automobile LED headlamp that has been the disclosure of the invention of 201410593767.X, including: lampshade, lamp holder, turnover panel light shielding device and radiator, luminescence chip is arranged at the above of radiator and side; Lamp holder is provided with main lens and widens mirror, is embedded in primary mirror mounting seat respectively and widens mirror mounting seat, and being fixed on fixing plate. This automobile LED headlamp, the requirement of high-power illumination can be reached, heat dissipation problem can be solved again, widen the width range of LED headlamp simultaneously, by extraneous induction apparatus or manual switching, intelligence or multifunction can be realized so that automobile LED headlamp reliability is greatly promoted, and realizes intelligent lighting. But its not can Automatic adjusument headlamp direction of illumination, can not self adaptation switching long-and-short distant light, existing defects.
Summary of the invention
The car headlamp of a kind of adaptive environment, including headlamp body, central processing unit, luminance sensor, height sensor, power governor, motor, radar.
Central processing unit is connected by wire with luminance sensor, height sensor, motor, radar, power governor respectively, and accesses automotive interior circuit.
Luminance sensor is fixed on car headlamp body front end by support, when sensing darkness or ambient light change when the light sensitive diode in luminance sensor, can export corresponding digital signal to central processing unit.
Height sensor is electro-optical pickoff, is arranged on vehicle front axle and hind axle, when headlamp is in running order, by detecting the side-play amount calculating two sensors of front and back wheel shaft, and side-play amount is passed to central processing unit.
Motor is arranged in car headlamp and is driven with lamp body by screw rod and is connected, and after central processing unit receives the side-play amount of height sensor, makes motor pass through screw rod forward or rotate backward and make lamp body driving up and down motion according to presetting formula.
Radar is range finding ultrasonic radar, is fixed on vehicle front lighting lamp body front end by support, and radar sends ultrasound wave, and the echo-signal that ultrasound wave will reflect back into passes to central processing unit, it is judged that front how much rice has pedestrian or vehicle.
Power governor is arranged in car headlamp, is connected with lamp body circuit, receives the instruction from central processing unit, controls the size of current of high-low beam light LED array by regulating resistance sizes, thus changing brightness and switching.
Central processing unit is connected with automobile circuit, monochrome information is transmitted according to luminance sensor, the echo-signal of radar transmission, central processing unit judges which presetting brightness section brightness is in, judge vehicle front pedestrian or vehicle distances, command adapted thereto is sent to power governor after comprehensive, control remote, the size of current of dipped headlights LED array and break-make, simultaneously, height sensor transmission front and back wheel axle offset amount, central processing unit judges whose height of front and back wheel shaft, and who is low, then sending command adapted thereto drives adjustment lamp body driving to make lamp body move up and down by motor by screw rod, change vertical irradiation angle.
In sum, the beneficial effects of the utility model are: automobile is in the process travelled, when headlamp works, can according to environment and road conditions automatic switchover long-and-short distant light, avoid the unreasonable use of long-and-short distant light, regulate light-illuminating angle simultaneously, irradiation distance and scope is made not to be affected substantially, improve the field range of driver, facilitate driver to observe surface conditions in time, bring convenience with other people to oneself, reduce the probability that vehicle accident occurs, and be automatically adjusted headlamp watt level and can save power supply, reduce energy resource consumption.
Accompanying drawing explanation
Below in conjunction with drawings and the embodiments, this utility model is described in further detail:
Fig. 1 is the structural representation of car headlamp in this utility model embodiment;
Fig. 2 is the side view of automobile in this utility model embodiment.
Each parts in figure, luminance sensor 1, radar 2, motor 3, power regulator 4, central processing unit 5, high beam LED array 6, dipped headlights LED array 7, height sensor 8.
Detailed description of the invention
As depicted in figs. 1 and 2, when car headlamp is opened, central processing unit 5, luminance sensor 1, height sensor 8, power governor 4, motor 3, radar 2 are started working. Light sensitive diode in luminance sensor 1 senses darkness or ambient light change, exports corresponding digital signal to central processing unit 5, and the echo-signal monitored is passed to central processing unit 5 by radar 2, makes after treatment and sends instruction.
When not having pedestrian with vehicle and without visible ray within front side 150 meters, high beam resistance value is adjusted to 0 by power governor 4, and dipped headlights resistance value is adjusted to 100%, and high beam LED array 6 is opened, and power is maximum.
When not having pedestrian with vehicle and have visible ray within front side 150 meters, high beam resistance value is increased 20% by power governor 4, and adjusting power is 80%.
When having pedestrian with vehicle and without visible ray within front side 75 meters to 150 meters, resistance value is increased 20% by power governor 4, and adjusting power is 80%.
When having pedestrian with vehicle and have visible ray within front side 75 meters to 150 meters, resistance value is increased 40% by power governor 4, and adjusting power is 60%.
When having pedestrian with vehicle and without visible ray within front side 75 meters, high beam resistance value is adjusted to 100% by power governor, and dipped headlights resistance value is adjusted to 0, and dipped headlights LED array 7 is opened, and power is maximum.
When having pedestrian with vehicle and have visible ray within front side 75 meters, dipped headlights LED array is opened, and dipped headlights resistance value is increased 40% by power governor 4, and adjusting power is 60%.
Front and back wheel axle offset amount is passed to central processing unit 5 by height sensor 8, and motor 3 is controlled after side-play amount being handled it according to formula by central processing unit 5.
When side-play amount be positive number and front axle higher than hind axle, motor 3 rotates forward, and screw rod drives and regulates lamp body and drive and makes lamp body move upward, and vertical irradiation angle is downward.
When side-play amount be negative and front axle lower than hind axle, motor 3 rotates backward, and screw rod drives and regulates lamp body and drive and makes lamp body move downward, and vertical irradiation angle is upwards.
These are only a specific embodiment of the present utility model, but design concept of the present utility model be not limited thereto that all insubstantial modifications utilizing this utility model design that this utility model is made each fall within protection domain of the present utility model.
