摘要： A discharge lamp provided with a U-shaped discharge tube and an outer envelope surrounding this tube. The bend of the discharge tube is supported with respect to the outer envelope by means of a metal member of sheet material. A few strips of this member engage the bend of the discharge tube. The metal member is composed of two parts twisted together which provide together a substantially light-tight transverse separation between the outer envelope and the discharge tube. The metal member maintains the bend of the operating lamp being kept at a relatively high temperature to improve luminous efficacy.

摘要： The invention relates to a low-pressure metal vapor discharge lamp comprising a discharge tube and an outer bulb enveloping the discharge tube. Provided between the discharge tube and the outer bulb are a barium-containing getter and an electrical resistor which, in operation assumes a temperature of at least 500.degree. C., for cracking CH.sub.4 gas.According to the invention, the resistor is enveloped for the greater part by a ceramic tube, which prevents the electrons emitted by the hot resistor from being deposited on the exterior of the discharge tube wall.
