Abstract: A lamp includes an enclosure with partitions defining a channel having channel segments and/or providing multiple paths for an electrical arc to travel. The channel segments can be implemented by adding additional electrodes in the channel formed by the partitions, by forming a channel where the arc may travel in multiple directions, or by a combination of these methods. The channel segments and multiple directions of arc travel tend to reduce the voltage required to start the lamp.

Abstract: An apparatus and method is disclosed for regulating the cold spot temperature of a light emitting enclosure. A cold spot regulation system defines and controls the temperature of the cold spot. The cold spot regulation system includes an interface housing secured to the light emitting enclosure and two ducts extending from the interface housing. The cold spot regulation system uses a coolant fluid to lower the operating temperature of the light emitting enclosure. The coolant fluid is diverted into one of the ducts. The coolant fluid is passed by the cold spot of the light emitting enclosure and released out the other duct.

Abstract: A light source incorporates light emitting diodes (LEDs). The LEDs may be raised off the floor of the optical cavity to permit light to be emitted from the base of the LED. Additionally, a reflective protrusion may be placed beneath the raised LED to aid in redirecting light forward. The LEDs may be skewed in relation to adjacent LEDs to reduce interference. Non-white LEDs may be incorporated into the light source to permit for selective color tuning. Fluorescent lamps may also be implemented in combination with the LEDs to form a hybrid light source.

Abstract: A light source incorporates phosphor-based white light emitting diodes (LEDs). The LEDs may be raised off the floor of the optical cavity to permit light to be emitted from the base of the LED. Additionally, a reflective protrusion may be placed beneath the raised LED to aid in redirecting light forward. The LEDs may be skewed in relation to adjacent LEDs to reduce interference. Non-white LEDs may be incorporated into the light source to permit for selective color tuning. Fluorescent lamps may also be implemented in combination with the LEDs to form a hybrid light source. The light source may be used as a backlight for a liquid crystal display assembly.
