Abstract
A high intensity discharge lamp assembly (10) has improved thermal venting. The discharge light source (12) is housed within a reflector body (20). Recesses (40) are circumferentially spaced around an open end (28) of the reflector body. A containment structure (50, 50′, 50″) provides a structure that serves the containment function without interfering with the thermal venting.
