Abstract

PROBLEM TO BE SOLVED: To easily convert to the illumination using LED by providing an electrode for taking the power source into a power source circuit portion, with the shape insertable into an electrode inserting port of a lighting system for a fluorescent lamp or an incandescent lamp. SOLUTION: A light source module 11 provides a shape, size, connection method with a power source and the outgoing characteristic of light almost equal to a fluorescent lamp 1, by using an LED. In the light source module 11, the light guide wave is obtained from a pattern on a surface of a light guide rod with pattern 12 to make a linear light source same as the fluorescent lamp 1. An illuminating portion comprises an LED array 13 and the light guide rod with pattern 12. Since the voltage converted into DC is to be applied to the LED, the power source circuit portion 14 must comprise a rectifying circuit and a voltage converting circuit. The electrodes 16, 17 for taking the power source are provided with the shape insertable into the inserting ports of the power source 16, 17 of the lighting system for the fluorescent lamp 1 or the incandescent lamp.
