<p>PURPOSE:To aim at compact construction of a lamp as a whole including its base, by joining two U-shaped glass tubes and fixing thereto, a base which has a socket engaging section projected along the diagonal line on a brim. CONSTITUTION:A lamp body 1 is made by joining two U-shaped glass tubes to make their surfaces opposing each other, while connecting the inner spaces of base sections 11, 12 on one side to each other through a connecting area 15 but hermetically sealing their inside from the outside. A socket engaging section 22 is provided along a diagonal line on a brim 21 with engaging projections 23 at both ends in the longitudinal direction and four base pins 24 are projectingly on the bottom. A base 20 is fixed with adhesive on an end plate 3 which makes the bottom of an luminous unit 1. By this construction, the base as well as the lamp body can be made in compact sizes while preventing the breakage of the lamp body and it is made possible to mount the lamp on a U-shaped fluorescent lamp socket.</p> |
