Abstract
A ceramic base for a tungsten halogen lamp has a bottom wall for supporting contact pins connected to respective lead-in wires sealed in the press-sealed end of the lamp. The base furthermore has a side wall integral with the bottom wall and at least one hole therein for receiving the press-sealed end of the envelope. The ceramic base side wall has convective vent passages including at least a first vent passage for inlet of cool air to the air space about the press-sealed end of the lamp, and at least a second vent passage for outlet of warmed air therefrom to thereby provide convective air cooling of the envelope press-sealed end.
