Abstract
The invention provides an illuminating lamp brightening slowly and dimming gradually. The illuminating lamp is characterized by comprising a 220V alternating current power source, a 12V half-wave rectification voltage regulation power source, a starting and slowly charging circuit, a triggering level forming circuit and an illuminating lamp drive circuit. A transition state does not exist between brightness of ignition and brightness of extinguishment of a general illuminating lamp; it is especially inconvenient for people to work or rest in a dark night environment when the illuminating lamp is turned on and completely bright or suddenly powered off and extinguished, and eyes cannot be adapted to the situation, besides, quite adverse influences are caused to the eyes; it is expected to design an illuminating lamp which is brightened slowly when a switch is turned on and dims slowly when the switch is turned off; if the work mode can be achieved, the physiological requirements of human eyes can be met, the service life of the illuminating lamp can be effectively prolonged, and the illuminating lamp can be more suitable for being used in the situation where mains voltage at night is excessively high due to the fact that the illuminating lamp can be brightened slowly and dim slowly.
Description
Technical field
The invention belongs to electronic auto-control technology field, be to fade off illuminating lamp about one is the brightest.
Background technology
Common illuminating lamp or delay illuminating lamp typical mode of operation be: or illuminating lamp unlatching i.e. all light,
Illumination lamp ignition works automatic distinguishing after a period of time, and illumination lamp ignition did not had to the brightness between extinguishing
Degree state.Especially between black night under environment, all light opened by illuminating lamp or power-off suddenly is extinguished, eyes wink
Between be far from suitable in the case of, the not only work of inconvenient people or rest, and the eyes of people are had very
Adverse effect.One illuminating lamp when opening luminous lamp switch can be designed light at leisure, shine closing
For to extinguish at leisure during bright lamp.If such mode of operation can be realized, one is that the physiology meeting people's eyes is wanted
Ask；Two is the service life that can effectively extend illuminating lamp；Three is that illuminating lamp can the brightest the most secretly be more suitable for
Night line voltage too high in the case of use.
Described further below of the present invention the brightest fade off illuminating lamp involved necessary in implementation process,
Guardian technique content.
