Adjustable Reflector Headlamp System Responsive to Oncoming Traffic

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 optical axis or the vertical optical angle to decrease illumination directed toward oncoming traffic. What is needed is a headlamp system that is responsive to oncoming.

The present invention is an adjustable reflector headlamp system that is responsive to oncoming traffic. The headlamp system utilizes adjustable reflectors in the headlamp housing to change the optical axis and horizontal optical angle to reduce the illumination directed toward oncoming traffic.

Figure 1 Vehicle with adjustable reflector headlamp system responsive to oncoming traffic

In Figure 1, vehicle 100 possesses an adjustable headlamp system responsive to oncoming vehicle 130. Light sensor on vehicle 100 detects oncoming vehicle 130, causing the present invention to change optical axis 110 and horizontal optical angle 120 to reduce illumination toward oncoming vehicle 130 as shown.

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. Optical axis 110 and horizontal optical angle 120 of illumination 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 vehicle oncoming traffic operates as follows. A light sensor on vehicle 100 detects oncoming vehicle 130. Light sensor send signal to C.P.U. when oncoming vehicle 130 is detected. C.P.U. changes optical axis 110 and horizontal optical angle 120 to reduce illumination directed toward oncoming vehicle 130 by changing angle of adjustable reflectors 220, 230, 240, and 250 of headlamp assembly 200 using motors 225, 235, 245, and 255.
