Abstract

PURPOSE:To emit light of temperature color approximate to that of an incandscent lamp, with high efficiency, by providing the first and the second prescribed fluorescent layers on the inside of an outer bulb made of glass. CONSTITUTION:A light emission bulb 4 is provided in an outer bulb 1 made of glass. The light emission bulb 4 has main electrodes 4b, 4c and an auxiliary electrode 4d for starting. The first fluorscent layer 5 is made on the inside of the outer bulb 1 from at least one of a fluorscent manganese-activated magnesium fluorogermanate and a fluorescent cerium-activated yttrium aluminate. The second fluorscent layer 6 is made on the first layer 5 from a fluorescent europium-activated yttrium vanadate or the like.
