<P>PROBLEM TO BE SOLVED: To provide an illumination fixture equipped with an adjustment function of a color temperature, using a simple constitution, without the use of a complex power supply circuit. <P>SOLUTION: For the illumination fixture 10, a translucent resin plate 3 having two kinds of phosphor regions 3a, 3b on a linear light source 2 is installed. By a means where the translucent resin plate 3 is substantially rotated, since a position of a boundary line between the two kinds of phosphor regions on the linear light source 2 is changed in the direction of extension of the linear light source on the linear light source, the color temperature can be changed gradually. <P>COPYRIGHT: (C)2010,JPO&INPIT |
