发明名称 METHOD AND SYSTEM FOR LASER PROJECTION AND HOLOGRAPHIC DIFFRACTION GRATING FOR A VEHICLE
摘要 The present invention is a method and system for projecting an image from a vehicle onto a surface, such as a road or sidewalk. A laser diode assembly is installed in the vehicle and comprises: a light beam source; a power source; a power regulating chip; an image creation means; and, power activating means. A lens is secured to an output end of the laser diode assembly, and comprises a light diffraction image which can be a message, logo, or graphic design Activation is initiated by switching on the assembly from a position within the interior of the vehicle, or by an activity such as the opening of a door. The activation is ramped up to a full-on state over a pre-set period of time.
