Adjustable Reflector Headlamp System

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.

The present invention is an adjustable reflector headlamp system in which the vehicle operator can adjust the optical axis, vertical optical angle and horizontal optical angle of illumination of the headlamp. The headlamp system utilizes adjustable reflectors in the headlamp housing to change the optical axis horizontal optical angle and vertical optical angle.

Figure 1A Vehicle with adjustable headlamp system

Figure 1B Vehicle with adjustable headlamp system

In Figure 1A and Figure 1B, vehicle 100, which possesses an adjustable headlamp system. Operator of vehicle 100 would be able to adjust declination angle 140 of optical axis 120, vertical optical angle 130 and horizontal optical angle 150.

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 120, vertical optical angle 130 and horizontal 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 operates as follows. The interior of vehicle 100 would contain controls for adjusting declination angle 140 of optical axis 120, vertical optical angle 130 and horizontal optical angle 150 of adjustable reflector headlamp assembly 200 by changing the angles of adjustable reflectors 220, 230, 240, and 250 using corresponding motors 225, 235, 245, and 255.
