  • Patent number: 8459839
    Abstract: A UV curing lamp has variable resistive ballast provided by at least one resistance alloy wire and a set of switches tapping varying positions along the resistance alloy wire. The variable resistance ballast defines the lamp's maximum operating power consistent with the power supply. The wire in combination with a fan also doubles as thermal ballast provided by air flowing across the wire onto the UV lamp. A detachable reflector in a generally parabolic cylinder shape directs light from the lamp located on the reflector's focal axis. The curing lamp with resistive ballast can be in the form of a handheld unit or as a floor unit with rotating lamps within the housing.

  • Patent number: 8354779
    Abstract: A heat sink for an LED downlight utilizes tilted fins forming helical air passages that can enhance thermal performance by 30% over conventional fins. To overcome the thermal challenge of installation within the stagnant hot air of insulated ceiling cans, a heat sink has an integral electrostatic air pump on its exterior, to move hot air downwards and drain the stagnant air from the can by establishing a chimney-like circulation up through the heat sink and back down around the outside of the heat sink. The air mover can be powered by a compact high-voltage, low-current power supply similar to those of neon signs. An embodiment of the heat sink is also revealed that is suitable for cooling an LED replacement for standard screw-in or equivalent light bulbs. This device can perform well in variety of orientations (horizontal, vertical, etc.) and fixtures.
