Abstract (en)
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. <IMAGE>
