Abstract
A lamp unit includes a pair of support members facing each other and three baseless fluorescent lamps supported parallel to one another by the support members. Each support member has three support recesses located at predetermined intervals. One end of each lamp is fixedly inserted into each corresponding support recess of one of the support member and the other end to each corresponding support recess of the other support member. Each lamp has a radiation window extending in the axial direction thereof. The lamps are positioned so that light beams emitted from the windows thereof intersect on a desired straight line.
