Abstract
LED lightings compatible with straight tube fluorescent lamp begin to be marketed for a factory, an office building and a commercial institution. But LED light for circle fluorescent lamp is difficult to be marketed due to high cost by geometric limitation. Therefore, we developed LED lighting compatible with circle fluorescent lamp for elevators. For the structure that we could change it easily by removing a fluorescent lamp with appliance, we realized low cost. We devised a light-emitting surface and appliance shape not to lose an expanse of the light that was characteristic of a round shape fluorescent lamp. It is the product which can secure the illumination equal with fluorescent lamp.
