<P>PROBLEM TO BE SOLVED: To provide a luminaire wherein illumination is not easily deteriorated even if lamp holders to sandwich a long lamp or holders to sandwich a tube covering the long tube are provided. <P>SOLUTION: This luminaire is formed so that the inner diameters of the holding parts 90, 90 of the lamp holders 9 are smaller than the outer diameter of a lamp 4, and holding spots 95 to sandwich the lamp 4 between the holding parts 90, 90 are four spots making almost point contact. Thereby, the surface temperature of a bulb 41 in the vicinity of the lamp holders 9 is not easily dissipated through the lamp holders 9, and deterioration of illuminance of the lamp 4 can be suppressed. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
