Lamps with reflector and respective image projection apparatuses

摘要

The lamp has a sealing portion (2) with one glass portion extending from a bulb (1) and another glass portion inside the former glass portion. A portion of a reflector (50) is formed with an air inlet (55) to introduce air flow striking against an upper portion of the bulb and coming into a lower portion of the bulb when the sealing portion is disposed to extend in a substantially horizontal direction. An independent claim is also included for an image projection apparatus.
