(54) | Electrodeless high intensity discharge lamp having a boron sulfide fill |
(57) An electrodeless high intensity discharge lamp including a sealed light-transmissive
lamp envelope, a volatilizable chemical fill and an inert gas or nitrogen within the
envelope. The primary active component of the fill is boron sulfide. The inert gas
or nitrogen within the envelope assists in starting the lamp, and is at subatmospheric
pressure. The lamp envelope is coupled to a high frequency power source to produce
a light emitting plasma discharge within the envelope. |
