摘要:
A rapid start fluorescent lamp contains a circuit opening device on the cathode mount which opens a short time after lamp starting and stops heater current flow to the cathode. The circuit opening device is a thermostatic element in a sealed glass tube. Additional support is provided for the cathode end that is connected to the circuit opening device in order to prevent damage from vibration.
摘要:
A fluorescent lamp has a transparent electrically conductive indium oxide coating on the inner surface of the fluorescent lamp bulb. A transparent coating of finely powdered titania is disposed on the conductive coating to improve its conductivity and a transparent protective coating of finely powdered aluminum oxide is then disposed on the titania coating.
摘要:
A fluorescent lamp has an extension base at one end thereof which contains an impedance to reduce current flow through the lamp. The length of the lamp plus extension base equals the length of a standard fluorescent lamp.

摘要:
A fluorescent lamp operating on reduced energy consumption includes a unique mount which carries a shield providing both a getter and a mercury dispenser. The lamp has a preferable fill of 80% neon and 20% krypton at a pressure of 2.0 Torr.
摘要:
A lamp assembly (10) comprises a base plate (12) having both an incandescent bulb (18) and a fluorescent bulb (16) affixed thereto. The incandescent bulb (18) acts as ballast and light source. A glow switch (26) and capacitor (27) act as starter and are contained within the base plate (12) or socket means (14). A starting aid (24) is impedance coupled into the series filament network.
摘要:
A fluorescent lamp contains a blend of phosphors to provide predetermined minimum power levels of radiation at predetermined spectral bands that are used in the analysis of liquid samples placed close to the lamp.
摘要:
An indium oxide coating is used on the inside surface of a vapor electric discharge lamp, such as a fluorescent lamp, to reduce the starting voltage. The coating is especially effective at low temperatures, but also reduces the voltage even at room temperatures. It is particularly useful also in lamps using certain mixed inert gases with the mercury, since the mixtures used generally require a higher starting voltage than the ordinary fluorescent lamps containing argon and mercury vapor.
