Abstract
An improved low pressure sodium vapor discharge lamp that is provided with an elongated discharge tube that can be curved no more than once, and an outer bulb that surrounds this tube, in which the thermal insulation of the lamp it is mainly achieved, by means of an internal infrared radiation reflector, which surrounds the discharge tube, the reflector being, in at least half of its area, transmitter of the visible light generated in the discharge tube, and in the that the sodium is present in excess and-if the ambient temperature around the lamp is about 20º c, the temperature of the coldest point of the discharge tube in the operating condition of the lamp is sufficiently small that said temperature of the point more cooling of the discharge tube in said range is achieved with an electric power supplied to the lamp of no more than 25 watts.
