Description
Technical field
The invention belongs to lighting electronic and power-saving technique field, relate to a kind of light-emitting diode aisle illuminating lamp.
Background technology
With common energy-saving lamp as aisle illuminating lamp or street lamp, for example: use minimum power 8W common energy-saving lamp, take and on average light 12 hours night every day as example, within 1 year, power consumption is: (8W * 12h) * 365 day=35KWh, that is: within 1 year, power consumption is about: 35 degree.
If aisle illuminating lamp or street lamp use light-emitting diode of the present invention aisle illuminating lamp, in the time of by day, 220V alternating current output voltage drops to 5V, the about 18mA of the alternating current passed through on electrochemical capacitor C2, and daytime, the power consumption of circuit was about 5V * 0.018A ≈ 0.09W.Take and on average light 12 hours night every day as example, within 1 year, power consumption is: (0.22W * 12h+0.09W * 12h) * 365 days=1.36KWh, that is: within 1 year, power consumption is about: 1.4 degree.As can be seen here: light-emitting diode of the present invention aisle illuminating lamp power consumption only has 1/25 of common energy-saving lamp power consumption, and power savings is very obvious, and both costs of manufacture also differ 3～4 times.
The circuit of light-emitting diode aisle illuminating lamp is all used common components and parts to make, and cost of manufacture only needs several yuans, is well suited for developing in batches for factory.
Below describe light-emitting diode of the present invention aisle illuminating lamp related relevant technologies content in implementation process in detail.
Summary of the invention
Goal of the invention and beneficial effect: with common 8W electricity-saving lamp, as aisle illuminating lamp or street lamp, within 1 year, power consumption is about: 35 degree, and use light-emitting diode of the present invention aisle illuminating lamp, within 1 year, power consumption is about: 1.4 degree.As can be seen here: light-emitting diode of the present invention aisle illuminating lamp power consumption only has 1/25 of common energy-saving lamp power consumption, and power savings is very obvious, and both costs of manufacture also differ 3～4 times.The circuit of light-emitting diode aisle illuminating lamp is all used common components and parts to make, and cost of manufacture only needs several yuans, is well suited for developing in batches for factory.
The circuit working principle: the 220V alternating current is after decompression capacitor C1, bleed off resistance R 1 step-down current limliting, carry out rectification by full-bridge rectification element QZ again, obtain about 12V direct voltage on electrochemical capacitor C2, using this voltage as high brightness light emitting diode LED 1～LED4 operating voltage, and the operating current of LED 1～LED4 is about 18mA.Because decompression capacitor C1 does not consume active power, the power that bleeder resistance R1 consumes is ignored.Therefore, the power consumption of whole circuit is about 12 * 0.018 ≈ 0.22W.
In order further to save the useful life of electric energy and prolongation high brightness LED, be provided with the photoelectric control circuit formed by photo resistance RG, resistance R 2 and NPN type triode VT1 etc. in circuit.When night, more than the resistance of photo resistance RG can reach 100K Ω, at this moment the voltage at electrochemical capacitor C2 two ends is supplied with the base stage of NPN type triode VT1 after photo resistance RG, resistance R 2 dividing potential drops, because DC offset voltage is very little, make NPN type triode VT1 cut-off, on the work of LED 1～LED4 without any impact; In the time of by day, due to photoelectric effect, the resistance of photo resistance RG can be reduced to below 1OK, at this moment NPN type triode VT1 conducting, because the electric current maximum by decompression capacitor C1 can only reach 18mA, due to the shunting of NPN type triode VT1, the voltage on electrochemical capacitor C2 drops to below 4V.
Because every light-emitting diode operating voltage requires to reach more than 2.8V just can start working, more than 4 series connection will reach 11.2V, so the 4V voltage on electrochemical capacitor C2 can not make LED 1～LED4 normally luminous.
So, after NPN type triode VT1 shunting " short circuit ", does why the power consumption of circuit diminish on the contrary? this is because capacity voltage dropping circuit is in the situation that output voltage is not too high, can basically can regard a constant-current source as, its power consumption is directly proportional to load resistance, after NPN type triode VT1 shunting makes the voltage drop on electrochemical capacitor C2, be equivalent to load resistance and reduce, so the power consumption of circuit just descends.
