摘要： PROBLEM TO BE SOLVED: To provide an arc tube in which the luminance in the downward direction can be improved by effectively utilizing the visible light excited from a phosphor by ultraviolet rays.
SOLUTION: A compact self-ballasted fluorescent lamp comprises this arc tube 2 in which a fluorescent film 10 is applied to the inside of a glass tube 9 curved and formed into a double spiral shape. The arc tube 2 has a turning section turning doubly around a turning axis A, and a turning-over section 91 that connects the two turning sections at the top part. In each cross section of the glass tube 9, the fluorescent film which is applied to the wall face on the end parts 94 and 95 side (P1b, P2b, P3b, P4b) of the glass tube 9 in a direction parallel with the turing axis A is made thicker than the fluorescent film applied to the wall face on the turning-over section side (P1a, P2a, P3a, P4a) in a direction parallel with the turning axis A.

摘要： PROBLEM TO BE SOLVED: To provide a compact bulb type fluorescent lamp suppressing temperature rising of an arc tube even when the arc tube emits light, and in addition, not so much dropping design properties.
SOLUTION: The compact bulb type fluorescent lamp 1 is equipped with a double helical arc tube 2; a holder 41 supporting the arc tube 2; a case 4 fitting the holder 41 and having a base 5; and a globe 6 covering the arc tube 2. The globe 6 is an A form type, and has a diffusion film for diffusing light emitted from the arc tube 2 formed on the inside. The arc tube 2 has a projecting part 93 which becomes the coldest spot part of the arc tube 2 when the lamp 1 is lit. The projecting part 93 is positioned on the helical axis of a double helical shape which is the shape of the arc tube 2, and thermally bonded to the globe 6 through a heat conductive medium 15.

摘要： PROBLEM TO BE SOLVED: To provide a compact fluorescent lamp where a bent fluorescent tube is thermally coupled with a globe through a heat-conductive resin such as silicon resin, and which keeps appearance well even if the heat-conductive resin ripples to wet the inside surface of the globe.
SOLUTION: The outside surface of a globe 5 is frost-treated so as to be provided with a light scattering layer. Even if the inside surface of the globe 5 ripples with the heat-conductive resin to go into a wet condition, the light which has transmitted through the globe 5 is scattered at the light scattering layer. So the border line of the rippling wet region is hard to tell apart, keeping the appearance of the compact fluorescent lamp.
