LED light sources for general lighting and large facility lighting are becoming more and more popular, and filament light bulbs and fluorescent lamps are rapidly disappearing from the market from the viewpoint of energy saving, but the outer diameter of a single light source such as a sensor light source for incorporating equipment is φ20. Most of the following small lamps have not been commercialized due to their market size, except for display applications using bullet-shaped LEDs.

However, the LED lamp technology compatible with the filament lamp as shown in Patent Document 1 (1) to Patent Document 1 (3) is effective as a light source for general lighting to large-scale facility lighting.
