Abstract

The present invention provides a high intensity discharge lamp with a lamp cap, which has a simple and firm structure, higher thermal stability, lower glare and higher efficiency than conventional lamps. The discharge lamp according to the present invention comprises an arcuate inner tube, which is filled with substances, e.g. xenon, for gas discharge. The arcuate inner tube comprises a bulbous or ellipsoidal portion.
Surrounding the arcuate inner tube is a tubular outer envelope; the outer envelope has an enlarged portion, which is similar to the bulbous or ellipsoidal portion disposed of the bulbous portion of the arcuate inner tube. The distance between the outer envelope and the outer wall of the arcuate inner tube is uniform; thereby making the temperature distribution on the wall of inner tube more uniform, which improves the thermal stability, and the luminous and the electricity parameters of the lamp. More important is that the invention can reduce the light refraction and reflection, which occurs between the inner surface of the outer envelope and the outer surface of the arcuate inner tube, and also between the two interfaces of the outer envelope wall and the space therebetween, thereby more light is directly emitted out from the enlarged bulbous portion of the lamp, and the occurrence of glare is reduced.
