<P>PROBLEM TO BE SOLVED: To realize weight reduction and energy saving of lighting fixtures, because the illumination lamp selling places in the town are in an inverter auction state while it is problematical in the viewpoint of fire prevention that very heavy fluorescent lamps are hung in the houses of old provincial families. <P>SOLUTION: Addressing weight reduction of a 100 V fluorescent lamp, the weight reduction has a lighting system by means of "irregular constant current circuit", and also it has been concluded that the output can be neither more nor less than 20 W without sacrificing energy efficiency. With reference to this fact, the output of all of fluorescent lighting fixtures of 32 W or more are changed to be 20 W, and lighting fixtures of 30 W or less are made to be "hybrid system" with a light-weight incandescent lamp as ballast, thereby outdoing high-class and excessively bright inverter lighting system. <P>COPYRIGHT: (C)2012,JPO&INPIT |
