Abstract
The invention relates to a slowly lighted on and off illuminating lamp. The slowly lighted on and off illuminating lamp is characterized by comprising a 220V alternating current power supply, an illuminating lamp slight-lighting and slow-charging circuit, a one-way silicon controlled rectifier slow-triggering circuit and a full-bridge rectification and illuminating lamp control circuit. When the illuminating lamp is turned on for lighting or is suddenly powered off at dark night, eyes cannot adapt to the light change instantly, the illuminating lamp not only brings inconvenience to work or rest of people and also has the very adverse influence on the eyes of the people. The illuminating lamp which can be slowly lighted on by turning on an illuminating lamp switch and can be slowly lighted off by turning off the illuminating lamp switch is designed. The achievable working modes are as follows: one, the eyes of the people are stimulated by strong light at night no longer, and the physiological requirements of the eyes of the people are met; two, the illuminating lamp can slowly bright and dark and is more suitable for usage under the situation of too high voltage of a mains supply at night, and the service life of the illuminating lamp is also effectively prolonged.
Description
Technical field
The invention belongs to electronics and lighting technical field, relate to one and slowly light and slowly extinguish illuminating lamp.
Background technology
Common illuminating lamp or delay illuminating lamp typical mode of operation be: otherwise illuminating lamp opens all light, or
Illumination lamp ignition works automatic distinguishing after a period of time, and illumination lamp ignition is to the brightness between extinguishing the most excessively
State.The people using over-illumination lamp had such experience, it is simply that exciter lamp filament is blown most generation
In the moment switched on power, especially suddenly open illuminating lamp at night, its filament be easy to by the late into the night higher
Voltage blows；Between black night, all light opened by illuminating lamp or power-off suddenly is extinguished, and moment eyes are far from suitable,
The not only work of inconvenient people or rest, and the eyes of people are had very adverse effect.Can design
One illuminating lamp when opening luminous lamp switch can light at leisure, when closing illuminating lamp for extinguish at leisure.
If such mode of operation can be realized, one be night people eyes be no longer influenced by high light stimulate, meet people's eye
The physiological requirement of eyeball；Two is that illuminating lamp can the brightest the most secretly be more suitable in the case of at night, line voltage is too high
Use, the most effectively extend the service life of illuminating lamp.
Of the present invention slowly lighting described further below slowly extinguishes illuminating lamp involved by implementation process
Necessity, guardian technique content.
Summary of the invention
Goal of the invention and beneficial effect: between black night, all light opened by illuminating lamp or power-off suddenly is extinguished, wink
Between eyes be far from suitable, the not only work of inconvenient people or rest, and the eyes of people are had the most unfavorable
Impact.One illuminating lamp when opening luminous lamp switch can be designed can light at leisure, close illumination
For to extinguish at leisure during lamp.If such mode of operation can be realized, one be night the eyes of people be no longer influenced by by force
Photostimulation, meets the physiological requirement of people's eyes；Two is that illuminating lamp can the brightest the most secretly be more suitable in city at night
Use in the case of piezoelectric voltage is too high, the most effectively extend the service life of illuminating lamp.
Circuit operation principle: after slowly lighting the activate switch SW connection slowly extinguished in lighting lamp circuit,
220V alternating current obtains the DC voltage of nearly 250V by full-bridge rectification, and its first one tunnel is given single through resistance R2
There is provided minimum conducting voltage to controllable silicon SCR, make unidirectional controllable silicon S CR just turn on, for illuminating lamp HL
The offer standby voltage of filament, and illuminating lamp HL shows as glimmer；Secondly another road DC voltage is through current limliting
Resistance R1 is that electrochemical capacitor C1 charges at a slow speed, along with the voltage at the two ends of electrochemical capacitor C1 is gradually increasing,
To be charged reach NPN type triode BG1 base bias voltage time, at this moment unidirectional controllable silicon S CR start by
Gradually turning on, the voltage at illuminating lamp HL two ends is also gradually increased, make illuminating lamp HL by secretly gradually brightening, this
Process takes around about 6 seconds；After about 15 seconds, NPN type triode BG1 is fully on, also again
Be exactly illuminating lamp HL filament by initial standby voltage, progressively obtain whole voltages of 220V alternating current, make
Illuminating lamp HL total power is luminous.
After activate switch SW disconnects, the electricity in electrochemical capacitor C1 will not release at once so that NPN
The base stage of type audion BG1 still maintains bias voltage, makes NPN type triode BG1 will not be completely switched off,
The partially ON of NPN type triode BG1 makes electrochemical capacitor C2 still can continue to be electrically charged, and adds electrochemical capacitor
The electricity having in C2, then unidirectional controllable silicon S CR can continue to be held on, along with the angle of flow is gradually reduced,
The brightness of illuminating lamp HL is the most dimmed, until NPN type triode BG1 is completely switched off, and electrochemical capacitor C2 two
The undertension of end is using during as trigger voltage, and illuminating lamp HL will be fully powered-off and extinguish.
Because illuminating lamp HL filament is carried out low-pressure heating in advance, thus efficiently avoid exciter lamp filament cold
Directly add full voltage, high voltage and big electric current during state and be easy to flash exciter lamp filament.
