The present invention principle be：220V alternating currents are about in 2 points of A, B alternating voltage after electric capacity C1, R1 are depressured current limliting
15V, rectification is carried out by VD1~VD4., about 14V DC voltage is obtained on C2 as high brightness LED VD5~VD8
Operating voltage, the operating current of light emitting diode is about 14mA.Because electric capacity C1 does not consume active power, bleeder resistance consumption
Power can be neglected, therefore the power consumption of whole circuit is about 15 × 0.04 ≈ 0-2 (W).
In order to further save electric energy and extend the service life of high brightness LED, added in circuit by photosensitive
The photoelectric control circuit of the compositions such as resistance R2, resistance R3 and triode VT1, night photo resistance R2 resistance up to 100K
More than, at this moment the voltage at C2 both ends is supplied to the DC offset voltage very little of VT1 base stages after R2, R3 partial pressure, and VT1 ends, right
The no any influence of work of light emitting diode；During daytime, due to photoelectric effect, R2 resistance can be reduced to 1OK with
Under, at this moment VT1 conductings and close to saturation, due to can only achieve 15mA by C1 electric current maximum, due to VTl shunting, on C2
Voltage can drop to below 4V.Because the operating voltage of each light emitting diode, which will reach more than 3V, to start working, four
Individual series connection will reach more than 12V, so at this moment light emitting diode is unable to normal luminous.After VT1 shunts " short circuit ", circuit
Power consumption diminishes.Because the circuit of capacitance decompression can substantially regard a constant current as in the case where output voltage is less high
Source, its power consumption is directly proportional to load resistance, after VT1 shuntings decline the voltage on C2, reduces equivalent to load resistance, so
Power consumption just have dropped.So that the alternating voltage at A, B both ends drops to 5V as an example, it is assumed that the alternating current passed through on C2 reaches 15mA,
At this moment the power consumption of circuit is about 5 × 0.015 ≈ 0.08 (W).Therefore exemplified by averagely lighting 12 hours at night daily, 1 year
Power consumption is：The ≈ of (0.2 × 12+0.08 × 12) × 365 1.2 (kWh), i.e., 1.2 degree electricity.Old electricity-saving lamp can be used in corridor lamp
Transformation of the way assembling.Original fluorescent tube is removed, it is the hole left just portalling as light emitting diode, bigger due to portalling, can
Four apertures are opened in the position of respective leds make substrate with hardboard.Do not have to remake circuit board during assembling, can use
Circuit board originally is assembled, and leaves 4 commutation diodes, and original 400V electrochemical capacitor is pulled down and changes 100 μ 25V's into
Electrochemical capacitor, the unnecessary component on circuit board is removed, other components in corridor lamp are taken using original solder joint
Weldering.Loophole of the hole as photo resistance is opened on the top of round shell, is easy to the light in the external world to be radiated at photo resistance
On.
