<P>PROBLEM TO BE SOLVED: To obtain a drop prevention configuration of a reflector 4, and to obtain an effective, large-output radiation configuration of a compact fluorescent lamp 9 that is likely to be affected by wind. <P>SOLUTION: An upper part 42 of the reflector 4 is provided by extending the upper part 42 to the upper part of a socket resin section, and an effective open hole for radiation is provided by reducing the temperature of the pipe wall of a lamp 9 for avoiding the flow of air in a ceiling and in a chamber by an extended upper reflector 42 and reducing light output. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
