Abstract (en)
[origin: EP0269958A2] A low power, high-pressure discharge lamp having a single pinch in which the two electrodes (4, 5) consist of a straight shank (15) and an angled electrode tip (16). The two shanks (15) are arranged parallel to one another; the tip of each electrode (4, 5) is designed as a pin (16) which is placed laterally on the end of the shank, the cross-sectional area of the pin (16) being greater than that of the shank (15) to ensure a high thermal capacity. <IMAGE>
