  • Patent number: 6903380
    Abstract: A method and system are taught for a system comprising an LED package. The LED package may comprise a leadframe having an annular contact and a base contact. An LED die may be coupled to the annular and base contacts such that the P-type material portion is electrically connected to an annular contact and the N-type material portion is electrically connected to a base contact. Alternatively the N-type material portion may be electrically connected to the annular contact and the P-type material portion may be electrically connected to the base contact. A lens may be coupled to the leadframe, and an optical material may be located in a cavity defined by the lens, the base contact, and the annular contact. The optical material may be a gel, a grease, a resilient material, a non-resilient material, a rigid material, a liquid material or a non-liquid material.

  • Patent number: 6541800
    Abstract: A method and system are taught for a system comprising an LED package. The LED package may comprise an anode, a cathode coupled to the anode, an LED die coupled to the cathode and the anode, a lens coupled to the anode, and a viscous or silicone material located in a cavity defined by the lens, the cathode, and the anode. The viscous or silicone material may be a gel, a grease, a non-resilient material, or a non-liquid material. The method and system may further comprise a mounting device, wherein the lens is mechanically coupled to the mounting device in a socket, bayonet, or screwing like fashion. The method and system may further comprise an anode strip comprising an array of anodes utilized to form an array of the LED packages and a carrier strip comprising receiving devices to receive the array of LED packages. A portion of the lens may either be coated with or comprise light excitable material or the viscous material may comprise light excitable material, such that the system emits white light.

  • Patent number: 6078145
    Abstract: An apparatus for simply retrofitting pre-existing vehicular incandescent hazard flashing lamps or strobe assemblies having high voltage wiring with low voltage, low-cost, two wire synchronized strobe lamp assemblies without requiring the altering of the vehicle's existing structure or wiring. The apparatus utilizes a high voltage d.c. to d.c. converter circuit which may be completely contained within the lamp housing so that no high voltage wiring will be routed through the vehicle. The strobe trigger circuit operates by sensing the ground potential at its input to trigger the strobe assembly's flash tube. This feature allows the synchronization of all circuit lamps, both incandescent and strobe, on a two wire flasher circuit without the need for a third wire to provide the trigger signal to the flash circuit. One embodiment of the invention works autosynchronously in conjunction with a standard electromechanical flasher relay as may be utilized in a typical vehicular warning light system.

  • Patent number: 5785413
    Abstract: A dual lamp fixture having an integral power supply and control circuit. The dual lamp fixture utilizes stroboscopic and incandescent lamps mounted near the focus of a parabolic reflector which may be actuated alternately, individually or simultaneously. Multiple lamps may be connected in parallel to a DC power bus and a differential line, twisted-pair communication bus to achieve a variety of controlled flashing patterns. Each lamp will perform its given tasks when an appropriate command signal is placed on the communication bus. To take full advantage of this distributed control and the advantages in bus-wiring topology, the power supply is located in close proximity to its controller and light fixture.
