<P>PROBLEM TO BE SOLVED: To solve a problem of a conventional luminaire having an all-night light, wherein a fine view such as a form of irradiated light of the all-night light reflected on a shade is not considered, and by no means it look attractive. <P>SOLUTION: A ring fluorescent lamp 30 is mounted to this luminaire 1 and an LED lamp is used as the all-night light 53 in it. The all-night light 53 has at least a part from the almost center position of a shade surface 20 to the minimum inner perimeter diameter of the ring fluorescent lamp 30 in a plane view as an effective irradiation range, and is structured so that when the all- night light 53 is lighted, no shade is produced in the effective irradiation range of the all-night light, or the area of the shade produced in the effective irradiation range of the all-night light is smaller than 5% of the effective irradiation range or larger than 90% thereof. <P>COPYRIGHT: (C)2003,JPO |
