METHOD FOR CONSTITUTING LIGHT TRANSMISSION BODY OF BICHROMAL LED AND ELECTRONIC APPARATUS USING LIGHT TRANSMISSION BODY OF BICHROMAL LED

摘要

PROBLEM TO BE SOLVED: To make the two colors of LEDs visible in uniform mingling even if short light transmission bodies are used and to obtain excellent appearance by arranging the LED light transmission bodies in positions where the LEDs of one color exist nearly at the center and installing the LEDs of another color in positions slightly part from the center. SOLUTION: The respective LEDs 102 to 104 consist of luminous bodies emitting, for example, colors of green and red in one package. The LEDs 102 to 104 are packaged on a printed circuit board 101 and the light emitted by the LEDs 102 to 104 is transmitted through the light transmission bodies 105 to 107 or is reflected on the wall surfaces and is introduced to the portions exposed to the outside of a casing. The displays of the LEDs 102 to 104 may be viewed by viewing the portions of the light transmission bodies 105 to 107 exposed from the casing. The one side among the light emitting portions of the bichromal LEDs 102 to 104 which are light sources, for example, the green portions are so arranged as to exist at the center of the light transmission bodies 105 to 107 and the luminous body portions of the other red are positioned at the edge portions of the light transmission bodies 105 to 107.
