In the late 1960s, they came into practical use, and in recent years they are also used in lighting equipment.

However, such a conventional lighting fixture has a lot of difficulties in implementing the desired color of light, the life of the lighting fixture is shortened due to a lot of heat generated by the characteristics of the incandescent lamp or neon tube. In addition, the lighting device using the LED is fixed in a certain direction of the light emission, the practical lighting effect is inferior, and there is a lack of compatibility with the existing incandescent lamp socket, there was a limit to blink each LED in a variety of production patterns.
