Abstract

The present invention is an adjustable reflector headlamp system that is responsive to the activation of the turn signal. The headlamp system utilizes adjustable reflectors in the headlamp housing to change the optical axis and horizontal optical angle to illuminate the anticipated direction of travel of the vehicle.

Adjustable Reflector Headlamp System Responsive to Activation of the Turn Signal

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 in anticipation of a vehicle making a turn. What is needed is a headlamp system that anticipates a vehicle making a turn.

The present invention is an adjustable reflector headlamp system that is responsive to the activation of the turn signal. The headlamp system utilizes adjustable reflectors in the headlamp housing to change the optical axis and horizontal optical angle to illuminate the anticipated direction of travel of the vehicle.

Figure 1 Vehicle with adjustable reflector headlamp system responsive to activation of the turn signal

In Figure 1, vehicle 100, which possesses an adjustable headlamp system responsive to activation of the turn signal is turning corner 110. Activation of turn signal when turning corner 110 causes the present invention to change optical axis 120 and horizontal optical angle 130 to illumination anticipated direction of travel as shown. The change in the optical axis 120 and horizontal optical angle 130 would be inversely related to the rate of travel of vehicle 100.

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 120 and horizontal optical angle 130 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 activation of turn signal operates as follows. Turn signal monitor on vehicle 100 sends signal to C.P.U. indicating direction vehicle 100 is turning. C.P.U. retrieves from speedometer monitor rate of travel of vehicle 100 and changes direction of optical axis 120 and increases horizontal optical angle 130 to illuminate anticipated direction of travel by changing angle of adjustable reflectors 220, 230, 240, and 250 of headlamp assembly 200 using motors 225, 235, 245, and 255. The change in the optical axis 120 and horizontal optical angle 130 would be inversely related to the rate of travel of vehicle 100.
