Abstract: This invention relates to circuits for operation over a range of voltages, more particularly for a vehicle lamp circuit that provides lighting over a range of voltages. The invention provides a circuit that allows the operation of an LED array lamp over a range of voltage. This is achieved by making use of three-terminal adjustable regulators. One of the three-terminal regulators is configured as a voltage regulator. It regulates the voltage by a connection to a voltage divider. A second three-terminal regulator is connected to the voltage regulator. The second regulator is configured to be a current regulator with the current set by one resistor. This circuit can be further modified with additional adjustable three-terminal regulators to increase in functionality.

Abstract: A vehicle lamp unit is disclosed that utilizes a high intensity discharge bulb for high beam, low beam and fog/driving lamps. The lamp uses reflectors and shields to selectively block light emitted from the HID bulb and to direct the light into a desired pattern. A control device is utilized to move the shields into various desired light blocking positions. Lamps of various shapes can be fabricated using the shield system by using optics to direct light into diverse preferred patterns.

Abstract: The subject invention describes a light assembly using light emitting diodes (LEDs) especially suited for use as a daytime running lamp. The catadioptric light assembly comprises a circuit board, a first set of LEDs secured to a first board, a first collimator disposed in front of the first set of LEDs for directing resultant parallel light beams to a reflective surface. The light beams are reflected by the reflective surface to an inner reflective surface of a housing and are directed, in a parallel fashion, to a lens. A second collimator is disposed in from of the second set of LEDs for directing the resultant parallel light beams directly to the lens. First and second support members, connected to the first and second boards, respectively, absorb and dissipate the heat generated by the LEDs.

The lens of the present invention utilizes two sets of optical elements, one set collimates and spread the light from the light emitting diodes and the second set reflects light from outside sources. Both sets of optics contribute to produce a marker lamp with the required light intensity and distribution according to industry standards. The marker lamp conceals a GPS antenna and/or a cellular antenna to help track and direct the vehicle during travel and to facilitate communication with the vehicle operator. The GPS tracking system and cellular components are at least partially by the marker lamp.
