不具合があった。However, as the auxiliary light source 3 of this type of embedded luminaire with auxiliary light source, a comparatively small light bulb such as a baby bulb is often used, and the auxiliary light source 3 is comparatively smaller than the main light source 2. It is arranged in close proximity. Therefore, when one or both of the main light source 2 and the auxiliary light source 3 are turned on, they are arranged close to each other in the same reflector 4, so that the output light of one light source is blocked by the other light source. Therefore, there is a problem that the light distribution characteristics are impaired.
【０００５】また、一方の光源を寿命などで取り替える
際には、他方の光源が交換の作業の邪魔になるなど手間
がかかった。Further, when one of the light sources is replaced due to the end of its service life, it is troublesome that the other light source interferes with the replacement work.
【０００６】特に、補助光源３を常夜灯や保安灯などに
