Abstract
The invention provides a delayed gradually-lighted-off illuminating lamp. The delayed gradually-lighted-off illuminating lamp is characterized by comprising a 220 V alternating-current power supply, a 9 V half-wave rectification and voltage stabilization power supply, a voltage-dividing startup circuit, a charge-discharge delaying circuit and an illuminating lamp driving circuit. Generally, the illuminating lamp is lighted off after being lighted on for a period of work, is only switched in a lighted-on state and a lighted-off state and has no brightness transition state between the lighted-on state and the lighted-off state. Especially in a dark night environment, the illuminating lamp suddenly loses power to be lighted off, a person cannot see anything instantly, inconvenience is brought to the person to go to bed for rest, and a very prominent influence is produced on the person's eyes. The brightness of the delayed gradually-lighted-off illuminating lamp is slowly reduced when the illuminating lamp is turned off, then the illuminating lamp is slowly lighted off. In the working mode, the illuminating lamp has the advantages that the physiological needs of the eyes of people are met, and the service life of a incandescent light bulb can be effectively prolonged.
