<p>A LUWPL luminaire has a housing (201) with a lower transparent closure (202) and a heat dissipating top (203), of cast aluminium. This has a suspension eye (204). The housing has an upper flange (205) via which it is bolted with the interposition of a seal 206 to a underside rim (207) of the top. Within the rim, the underside (208) is substantially flat, with a magnetron attachment boss (209) and other attachment points (210). A magnetron is supported by being clamped by a saddle (220) to the attachment boss (209) at the magnetron's anode. The magnetron is fast with a transition box and a crucible support block. A bracket (221) fixed to certain of the attachment points (210) extends down from the top and is screwed to the transition box. Thus the LUWPL parts are securely supported below the top.</p> |
