The product of LED light modulation in the market, of a great variety, dimming mode is multifarious, business, office and industrial aspect among a small circle in Intelligent Light-control System have in use, but control system cost compare is expensive, and reproducibility is not high, track remodelling bothers, and energy-saving effect is undesirable.Same household aspect light adjusting controller cost is general higher, and popularity rate is low, and energy-saving effect is not obvious.
Current business, public lighting area such as office field, building etc. need longer lighting hours or 24 lab scale continuous illuminations mostly, and when in regular hour section, flow of the people is rare, LED lamp keeps same brightness in work always, is also a kind of wasting of resources.
Summary of the invention
The utility model, for existing LED illumination lamp driving power, is studied improvement, provides a kind of Novel LED energy-saving driving power circuit, and illumination is uninterrupted, makes LED more energy-conservation.
The technical solution of the utility model is as follows:
The utility model discloses a kind of Novel LED energy-saving driving power circuit, it is characterized in that: comprise interface P1, P1 1 pin connects power supply+5V by connecting luminous tube D1, resistance R1 to single-chip microcomputer U3 7 pin, interface P1 2 pin is connected to single-chip microcomputer U3 6 pin, interface P1 3 pin is connected to single-chip microcomputer U3 5 pin, interface P1 4 pin is connected to secondaryly, composition single-chip microcomputer signal input circuit, single-chip microcomputer U3 2 pin connects power supply+5V by connecting electric capacity C1 to 4 pin, single-chip microcomputer 4 pin is connected to secondaryly, single-chip microcomputer U3 8 pin contact resistance R2 to optocoupler U2 2 pin, optocoupler U2 1 pin is connected to and forms single-chip microcomputer signal output switch control circuit secondaryly, power drives chip U1 8 pin, 9 pin are connected to elementaryly, and power drives chip U1 13 pin contact resistance R3, electric capacity C2 are to elementary, and contact resistance R4 to optocoupler U2 3 pin, optocoupler U2 4 pin is connected to ground, composition signal receiving circuit.
Advantageous Effects of the present utility model is: the utility model has very large advantage on the energy-conservation of LED power and installation cost, energy-saving effect is obvious, power save mode is flexible, and energy-conservation power consumption to preset scope 0-100%, and the energy-conservation time sets according to customer demand; Installation cost is lower, and LED lamp installation region does not need extra energy-saving control system, easily installs.
Accompanying drawing explanation
Fig. 1 is the preferred circuit theory diagrams of one of the present utility model.
Embodiment
Be described further below in conjunction with the embodiment of accompanying drawing to utility model.
As shown in Figure 1, the utility model discloses a kind of Novel LED energy-saving driving power circuit, it is characterized in that: comprise interface P1, P1 1 pin connects power supply+5V by connecting luminous tube D1, resistance R1 to single-chip microcomputer U3 7 pin, interface P1 2 pin is connected to single-chip microcomputer U3 6 pin, interface P1 3 pin is connected to single-chip microcomputer U3 5 pin, interface P1 4 pin is connected to secondaryly, composition single-chip microcomputer signal input circuit, single-chip microcomputer U3 2 pin connects power supply+5V by connecting electric capacity C1 to 4 pin, single-chip microcomputer 4 pin is connected to secondaryly, single-chip microcomputer U3 8 pin contact resistance R2 to optocoupler U2 2 pin, optocoupler U2 1 pin is connected to and forms single-chip microcomputer signal output switch control circuit secondaryly, power drives chip U1 8 pin, 9 pin are connected to elementaryly, and power drives chip U1 13 pin contact resistance R3, electric capacity C2 are to elementary, and contact resistance R4 to optocoupler U2 3 pin, optocoupler U2 4 pin is connected to ground, composition signal receiving circuit.
Operation principle of the present utility model is as follows:
Power drives chip U1 13 pin series resistance R3 is to ground, when resistance R3 impedance is reduced in certain limit, the voltage of power drives chip 13 pin starts to decline, and power supply chip U1 adjusts reduction power output automatically according to the change in pressure drop of its 13 pin, thus reaches energy-saving effect; The main function of U3 single-chip microcomputer is clock control, user can pre-set energy saving period, stored by single-chip microcomputer and control, when single-chip microcomputer starting energy-saving pattern, signal is transferred to resistance R4 by optocoupler U2, resistance R4 circuit turn-on and resistance R3 form parallel circuits, draw power driving chip U1 13 pin voltage, power drives chip U1, according to the decline scope of 13 pin voltages, adjusts power output automatically, and then complete machine power decreases, reach energy-conservation object.
