A solder glass which has, by weight: about 60 to 67% Sb O ; about 27 to 32% B O ; and from greater than 0 to 10% ZnO. The glass has a softening point between 388 and 466Â C. , depending on the ZnO content. The glass can be employed as a molten seal in electrical devices such as tungsten halogen or metal halide lamps.

A lamp envelope is provided with an alumina layer and a multilayer phosphor coating on the alumina layer. The phosphor coating includes a top phosphor layer with a first weight percent of rare earth activators and a middle phosphor layer with a second weight percent of rare earth activators. The second weight percent is less than the first weight percent so that a total amount of the activators in the coating is reduced while maintaining a required lamp brightness and color rendering index (CRI). Preferably, the second weight percent is about 50-60% of the first weight percent and the middle layer is about 30-50% of a total weight of the coating so that a total weight of the activators in the coating is no more than about 80% of a weight of the activators in the coating if the first and second weight percents were the same.

An energy saving gas discharge lamp, and method of making same, is provided. The gas discharge lamp includes a light-transmissive envelope, and an electrode within the light-transmissive envelope to provide a discharge. A light scattering reflective layer is disposed on an inner surface of the light-transmissive envelope. A phosphor layer is coated on the light scattering reflective layer. A discharge-sustaining gaseous mixture is retained inside the light-transmissive envelope. The discharge-sustaining gaseous mixture includes more than 80% xenon, by volume, at a low pressure.

A phosphor blend is described wherein the blend consists of a red-emitting rare earth phosphor, a green-emitting rare earth phosphor, and a blue-emitting rare earth phosphor wherein the 50% size of the phosphors is between about 12 to 15 μm. The phosphor blend is incorporated into a fluorescent lamp having an increased efficacy. A dual layer coating may be used to provide an additional increase in efficacy.

A ballast including an inverter circuit for providing an oscillating power signal for energizing at least one lamp. The inverter circuit includes a first transistor having a first gain and a second transistor having a second gain, each configured for alternately operating between a conductive state and a non-conductive state. The power signal has a waveform cycle comprising a first pulse generated when a first transistor operates in a conductive state, and a second pulse generated when the second transistor operates in a conductive state. The integral value of the first pulse of each waveform cycle of the power signal is different from the integral value of the second pulse of each waveform cycle such that a differential relationship between the first gain and the second gain is greater than or equal to a minimum value in order to minimize lamp striations.

A skin tanning fluorescent lamp having a coating of a uniform and homogeneous deflocculated physical mixture of a first and second phosphor where the first phosphor has a desired emission in the spectral region from about 320 to about 400 nanometers and the second phosphor has a desired emission in the spectral region from about 280 to about 320 nanometers, said first phosphor has a first isoelectric point at a first pH and the second phosphor has a second isoelectric point at a second pH. The first and said second pH form a range. The deflocculated coating is stabilized by deflocculating the first and second phosphors at a third pH sufficiently outside of range to produce a resulting coating consistently having desirable emission during production.
