FIELD: electrical engineering; incandescent lamps. ^ SUBSTANCE: proposed incandescent lamp is characterized in that its filament is molten tungsten disposed in slots made in heat-pipe cooled ceramic base and that its operating temperature is optimal for light engineering. Used for the purpose is ordinary and not high-purity, nor single-crystalline tungsten which essentially. ^ EFFECT: enhanced efficiency and reduced manufacturing cost of lamp. ^ 3 cl, 1 dwg |
