<P>PROBLEM TO BE SOLVED: To solve problems that, when the variable control of respective colors of RGB and the dimming control of low luminous flux are carried out in an RGB color-variable lighting fixture, the number of lamps and circuits to control the lamps are complicated, thereby causing a disadvantage to require a large-sized lighting fixture. <P>SOLUTION: A color temperature-variable illumination environment is constituted of one lamp. Concretely, the lamp includes: a substrate having printed wiring provided thereon; solid light-emitting body element groups each having a plurality of solid light-emitting body elements serially-connected on the printed wiring of the substrate; bases including a connection pin commonly connected to one end of the plurality of the solid light-emitting body groups and a plurality of connection pins connected to other ends of the plurality of the solid light-emitting body groups; and a tube having the bases. <P>COPYRIGHT: (C)2011,JPO&INPIT |
