Adjustable Reflector Headlamp System Responsive the Rate of Travel of the Vehicle

Automobile and trucking manufactures desire to improve their products' attributes and differentiate their products by adding feature to vehicles that are responsive to driver needs. A headlamp that is responsive to environmental factors or driving conditions serves both these functions. One problem with conventional vehicle headlamps is that they do not adjust the declination angle of the optical axis or the vertical optical angle to the rate of travel of the vehicle. What is needed is a headlamp system that is responsive to the rate of travel of the vehicle.

The present invention is adjustable reflector headlamp system that is responsive to the rate of travel of the vehicle. The headlamp system utilizes adjustable reflectors in the headlamp housing to change the optical axis and vertical optical angle to the rate of travel of the vehicle.

Figure 1 Vehicle with adjustable reflector headlamp system responsive to the rate of travel of the vehicle

In Figure 1, vehicle 100 possesses an adjustable headlamp system responsive to rate of travel of vehicle 100. Speedometer monitor on vehicle 100 sends signal to C.P.U. proportional to rate of travel of vehicle 100. The C.P.U. increases declination angle 140 of optical axis 130 and decreases vertical optical angle 150 of headlamp 110, the faster vehicle 100 is traveling.

Figure 2 Adjustable reflector headlamp assembly

Figure 2 illustrates the adjustable reflector headlamp assembly 200. Adjustable headlamp assembly 200 includes a bulb 210, top adjustable reflector 220, top motor 225, left adjustable reflector 230, left motor 235, bottom adjustable reflector 240, bottom motor 245, right adjustable reflector 250 and bottom motor 255.

Bulb 210 emits light, which is reflected by adjustable reflector 220, 230, 240 and 250. Declination angle 140 of optical axis 130 and vertical optical angle 150 of adjustable reflector headlamp assembly 200 can be altered by changing the angles of adjustable reflectors 220, 230, 240, and 250 using corresponding motors 225, 235, 245, and 255.

Adjustable reflector headlamp system responsive to the rate of travel of the vehicle operates as follows. Speedometer monitor on vehicle 100 sends signal to C.P.U. proportional to rate of travel of vehicle 100. The C.P.U. increases declination angle 140 of optical axis 130 and decreases vertical optical angle 150 of headlamp 110, the faster vehicle 100 is traveling by changing angle of adjustable reflectors 220, 230, 240, and 250 of headlamp assembly 200 using motors 225, 235, 245, and 255.
