Abstract
A lamp assembly providing a three dimensional lamp image may be animated by driving the mirror portion with an electromechanical device responsive to a varying input signal. The three dimensional image can then be reshaped in response according to a preferred input signal.
Claims23
A dynamic lamp assembly comprising:
- a reflector having a mirrored surface oriented axially to face a field to be illuminated, the reflector including a perimeter;
- a partially light reflective and partially light transmissive lens having a first surface facing the reflector, the lens further being offset from the mirrored surface, thereby defining a cavity intermediate the reflector and the lens,
- at least one LED (light emitting diode) light source capable of emitting visible light, positioned near the cavity and oriented to direct light into the cavity intermediate the reflector and the lens;
- the lens having a second surface facing the field to be illuminated, the first surface reflecting more than four percent of incident visible light directly from the LED light source and transmitting more than four percent of incident directly from the LED light source;
- and
- an electromechanical transformer providing a mechanical output in response to an electrical input signal, the transformer being mechanically attached to the mirror.

A vehicle lamp comprising:
- an electric light source directing light to
- an optical projection assembly having
- a light pattern forming element and
- at least one a light path altering element,
- the light pattern forming element and the at least one light path altering element having a passive positional relation with the light pattern forming element, whereby light projected passively from the optical projection assembly forms a stabile light beam with a pattern, and an electromechanical device receiving a signal input and generating a mechanical motion in a mechanically driven element in response to said input signal, the driven element being fixed to the optical projection assembly to alter the passive
- positional relation between the light pattern forming element and a light path altering element.
