<P>PROBLEM TO BE SOLVED: To suppress white turbidity of a UV cutting film during a manufacturing process in a compact triple tube lamp with the UV cutting film. <P>SOLUTION: When the inner tube outer diameter is od[mm], the outer tube inner diameter is ID[mm], the outer tube outer diameter is OD[mm], the rated lamp power is P[W], and the square root of a lamp power value is Ps, the lamp is made to satisfy od(ID-od)/Ps(OD-ID)≥3.48, 1≤(OD-ID)≤2, 70≤P≤100, and OD≤29 in a cross section including the minimum space between the outer tube inner surface and the inner tube outer surface in a light-emitting space in which both end faces of a light-emitting tube light-emitting part is extended in the outer diameter direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
