Fluorescent-lamp protection device in an electronic instant starter assembly

Abstract From the Canadian patent

A fluorescent lamp protection device which comprises, a solid state timer for controlling the state of a delay-and normal-closed contact so as to control a starter of a fluorescent lamp; the delay-and-normal-closed contact is connected in series with an auxiliary starting capacitor and then both of them are connected in parallel with all original starting capacitor. The operation power supply of the solid state timer is a D.C. power supply provided by the instant starter of the fluorescent lamp. During the lamp being lit, the auxiliary starting capacitor is used for reducing the instantaneous pulse voltage applied to both end of the fluorescent lamp so as to protect the lamp and to increase …
