Abstract
Composite high intensity discharge lamp constructions are described adapted for use in the recovery, in the form of heat, of energy in the non-visible frequencies emitted by such lamps. A transparent sleeve is disposed around and spaced from the lamp body being directly or indirectly connected thereto. Air passing between the sleeve and the lamp is brought into intimate heat transfer contact with both the outer surface of the lamp outer envelope and the inner surface of the sleeve.
