Abstract: An LED lamp that couples a heatsink with LEDs mounted on it to a glass envelope with a surface area equivalent to approximately that of a conventional light bulb, and by using a coolant vapor within the glass envelop, the lamp can be made much lighter and more cheaply. The heat generated by the LEDs is dissipated by the glass surface and not conducted into the heatsink. The heatsink can thus be mostly for the power supply. This allows for a reduced operating temperature for the power supply components that allows for a longer expected life for the power supply. In addition, the LED light bulb of the present invention can have nearly the same shape and appearance as a standard incandescent bulb. The invention can also have an advanced flyback power supply.

Abstract: LED or other lamps that remove heat using evaporation of water or other coolant inside a lamp enclosure structure such as a glass bulb typically without the use of external heat sinks or fins. Optionally, the pressure inside the enclosure can be reduced to lower the boiling point of the coolant. One or more LEDs or other light source can be mounted on a support structure that conducts heat to an evaporation surface. A coolant, preferably water or alcohol (or a water/alcohol mixture), is included inside the structure and can be optionally wicked to the evaporation surface. Vaporized coolant condenses on the inside surface of the enclosure or bulb transferring heat to the ambient through the enclosure. The condensed liquid coolant can return to a pool in the bottom of the enclosure.

Abstract: A power supply module for a lighting system is directly mountable onto a special cover plate for a standard electrical junction box. The power supply module is provided with a plug assembly that mates with a socket assembly incorporated within the special cover plate. The power supply circuit provides an electronically power limited output through multi-conductor connectors. The power supply output is used to connect to luminaires using a multi-conductor cable having multi-conductor connectors that mate with the multi-conductor connectors on the power supply and the luminaires. The luminaires use a circuit to interface between the power supply output and the lamp. The special cover plate is also suitable for receiving a plug assembly incorporated within the base of a lighting base module that can provide temporary incandescent or gas-discharge lighting.

Abstract: A luminaire has a ballasting circuit assembly for a gas discharge lamp, with an input power connector assembly suitable for receiving and connecting with a mating multi-conductor connector assembly. A ballasting circuit in the ballasting circuit assembly is suitable for powering a gas discharge lamp. Output leads suitable for connecting to a gas-discharge lamp socket with the wiring therefor are contained within the luminaire.

Abstract: Disclosed is an improved combustion products smoke alarm that includes an electronic circuit which automatically tests the detector's operation repetitively at periodic intervals, or periodically sounds the detector's alarm to remind the occupant to manually test the detector's operation. In the preferred embodiment, this periodic testing or reminding occurs at weekly intervals. Thus, occupants living about such a smoke alarm, after experiencing this repetitive sounding of the detector's alarm for some time, will come to anticipate its sounding and notice its absence if the smoke alarm becomes inoperative.
