Title: Portable multicolor signal lamp
Inventor: SUZUKI KATSUO
IPC: F21L4/00
Filed: 1995-04-11
Abstract: PURPOSE: To make a signal lamp emit only a desired color by slidingly moving a lamp chimney which is equipped in its barrel part with cylindrical translucent bodies separately colored in many colors and formed into a plurality of tiers. CONSTITUTION: While a base body case 1 is held by one hand with a luminescent body 3 turned on by switch operation, a lamp chimney 6 is moved slidingly in the longitudinal direction with a hold part 6a grasped by the other hand. The lamp chimney 6 is stopped transiently by notches 18 at positions where the luminescent body 3 corresponds to the central part of each of cylindrical translucent bodies 12a, 12b, and 12c. When the luminescent body 3 is stopped at the position of one of the cylindrical translucent bodies, for example 12b, light of a color put in to the cylindrical translucent body 12 in question is emitted.  Because a shading screen 15 is located on the boundary with the neighboring cylindrical translucent body 12a, irradiated light (i) from the luminescent body 3, being shut off by the shading screen 15, does not come through into the neighboring cylindrical translucent body 12a. It is therefore ensured that only the single cylindrical translucent body 12 in question is turned on and emits light. When the lamp chimney 6 is moved farther, the luminescent body 3 is moved accordingly and stops at the position of the focal point of a parabolic mirror 10.
