Abstract

A high pressure gas discharge lamp, including: an arc tube (110) comprising an arrangement of electrodes (104, 109a, 109b) and containing mercury, wherein, in order to generate radiation, the electrodes (104, 109a, 109b) are arranged to sustain an electric arc to vaporise the mercury (111) within the arc tube (110), said arc tube being arranged to generate radiation in at least the UV-C, UV-B, UV-A and visible optical ranges; and an optical filter (114) that is optically opaque to UV-C radiation and optically transparent to UV-B, UV-A and visible radiation, wherein the optical filter (114) is arranged to block UV-C radiation emitted from the arc tube (110) and allow transmission of UV-B, UV-A and visible radiation emitted from the arc tube (110). A luminaire (450; 750) is also disclosed.
