ABSTRACT:
A discharge lamp (10) based on microwave excitable sulfur gas with enhanced red component of visible light emission from the lamp as a whole, the lamp having an arc discharge tube (18) light source, microwave excitation means (M) and an outer inert zone around the arc discharge tube having a layer of phosphor (16) selected to absorb a portion of blue-green spectral component of the arc discharge tube emission and emit a concentrated red region of spectral range of light to combine with non-red spectral components of light passing through the phosphor. The phosphor can be essentially homogeneous material or may comprise a mixture of distinct phosphor types and/or a multi-layered array.
