Abstract

PURPOSE:To increase lamp efficiency by installing a discharge path regulating body in a bulb and thinning the film thickness of the first phosphor layer of inner surface of the bulb than that of the second phosphor layer formed on the surface of the discharge path regulating body. CONSTITUTION:The first phosphor layer 2 is formed on the inner surface of a bulb 1, and a discharge path regulating body 3 is so installed that the space inside the bulb 1 is divided into four, and on the surface of which the second phorphor layer 4 is formed. The discharge path formed between a pair of electrodes 5 is lengthend to form a small fluorescent lamp. When the film thickness of the first phosphor layer 2 is T1, that of the second phosphor layer 4 formed on the surface of the discharge path regulating body 3 is T2, it is so formed that the relation of T1<T2 is satisfied. Therefore, since the absorbing amount of ultraviolet ray from a positive column on the second phosphor layer 4 can be increased, lamp efficiency can be efficiently increased.
