Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this kind Energy-Efficient Led Street Lamp Lighting Control Assembly, comprise power supply module 101, timing control unit 102, photo-electric control unit 103, switch control unit 104, driver element power module 105 and many drive circuit modules group 106, wherein many drive circuit modules group 106 is to be made of several same driver element 107, each unit concurrent working.Shown in Figure 2 is the power supply module, timing control unit, the photo-electric control unit, the electrical schematic diagram of switch control unit, 103 inside, described photo-electric control unit are exported high after logic control, low level signal, this signal is directly sent into switch control unit 104, the shutoff of control switch circuit or conducting, simultaneously, the output of photo-electric control unit 103 divides with the power input part of timing control unit 102 and links to each other, the initial timing of control circuit constantly, the output of timing control unit 102 drives relay J, and with two auxiliary contact J1 of relay, J2 is serially connected in respectively in the driver element 107 circuit constant currents output branch road.Fig. 3 is the electrical schematic diagram of driver element power module and single driver element.In such scheme, constant-flow driver adopts step-up DC/DC transducer, and each driver element can drive at least 80 LED lamps.In Fig. 2, select for use elementary 220V, secondary 15V, 5W power transformer, select 1N4007 type diode for use; A1-A2 selects LM339 type voltage comparator for use; LED selects φ 5mm red light emitting diodes for use; VT selects the silicon triode of 9013 types for use; VO selects MOC3061 type light activated power thyristor for use; VS selects the withstand voltage 600V of BT136 type for use; RP1, RP2 are the potentiometer of 100k.RG can select cadmium sulphide photoconductive cell for use, as the MG45 type; J selects the relay of the attached contact of JQC-3FO type band for use.Other element as shown in the figure.Output port 11 is connected to Fig. 3 circuit supply with the input port 22 of Fig. 3.Among Fig. 3, as all switch mode converters, select inductance to make choice exactly between efficient and electroplax plate area, bigger inductance value can provide littler impedance, higher efficient and bigger saturation current rated value.Less inductance then uses less board area, and the saturation current rated value is also less, but coil impedance is bigger, so whole efficiency is lower.With reference to explanation document and the actual debugging of the relevant XC9013 of Torex company, L chooses 22 μ H; CL can directly influence output ripple voltage, so the output capacitance of 20 μ F is used in this design; CIN helps the output impedance of stabilized power supply, and this circuit is selected the ceramic input capacitance of 1 μ F for use; With reference to the explanation document of the relevant XC9013 of Torex company, CFB and CDD select 130PF and 1PF respectively for use; Resistance R SENSE with reference to the technical documentation of the relevant XC9013 of Torex company, selects 0.1 Ω as current detecting for use; Because the revers voltage of power supply protection diode (CIN among the figure) helps the output impedance of stabilized power supply; be operated in the high frequency of 300kHz; need to adopt recovery time little and forward voltage drop is little, the revers voltage rated value is greater than the Schottky diode of the voltage at LED two ends, its operating current I

1/2, this circuit selects MA737; RFB1 among the figure, RFB2 resistance value are selected 2.5 Ω and 3 Ω respectively for use; LED selects the white light LEDs luminous tube for use, and rated voltage is 3V, and electric current is 20MA.
Shown in Figure 2, the photo resistance RG resistance under the solar light irradiation by day is less, and the M point voltage on the RP1 is higher, so the negative input end of A1 is higher than the voltage of positive input terminal, and its output output low level.Make through R6, LED that VT ends, VO is obstructed, VS turn-offs, the power supply of street lamp driver element 107 disconnects.The low level of the output of A1 makes CD4060 because of the failure of oscillations of non-transformer voltage simultaneously, and the negative input end of A2 is because of input low level, its output output high level, and relay gets.The normally opened contact J2 and the normally-closed contact J1 that are attracted by relay J in the street lamp driver element 107 are failure to actuate.To night, it is big that the RG resistance sharply becomes, and the M point voltage reduces rapidly, when the negative input end of A1 is lower than the voltage of positive input terminal, and its output output high level.One the tunnel makes VT saturation conduction, VT drive the VO conducting through R6, LED, and VO triggers the VS conducting again, so the power connection of street lamp driver element 107.Another road provides supply voltage for 16 pin of CD4060, and the oscillator that its internal circuit and RP2, C3 form begins starting of oscillation, frequency of oscillation f=1/2.2RP2C3HZ.The frequency of 3 pin clock signals is 1/2 behind frequency divider ten level Four frequency divisions
142.2RP2C3HZ the cycle is 2
142.2RP2C3s corresponding timing is 2
132.2RP2C3s.In timing, the CD4060 output is output low level all the time, the negative input end voltage of A2 is lower than the voltage of positive input terminal all the time around here, its output is exported high level all the time, at this moment, relay J keeps "on" position, and normally opened contact J2 and the normally-closed contact J1 of street lamp driver element 107 repeat circuit J are failure to actuate, and street lamp keeps normal illumination brightness.Greatly about about zero point, when vehicular traffic and personnel are rare, timing finishes, the CD4060 output becomes high level by low level automatically, the negative input end of A2 is higher than the voltage of positive input terminal, its output pin output low level, relay J dead electricity, normally opened contact J2 and normally-closed contact J1 action in the street lamp driver element 107, street lamp keeps dark brightness of illumination state.During to dawn, the output pin of CD4060 becomes low level again, and makes the negative input end of A2 be lower than the voltage of positive input terminal, its output output high level.This moment, relay J is recovered "on" position, and street lamp keeps normal illumination brightness again.At day the resistance of RG diminishes, and the M point voltage raises, and when the negative input end of A1 is higher than the voltage of positive input terminal, its output becomes low level by high level automatically, and VT is ended, street lamp driver element dead electricity, and street lamp extinguishes automatically.Simultaneously, CD4060 is because of losing the supply voltage failure of oscillations, and automatic clear is for preparing from zero timing once more night.
In the system shown in Figure 3, driving current value equals the resistance of FB control voltage divided by company resistance.The FB control voltage of XC9103 is 0.9V, therefore by changing resistance value, the LED drive current can be adjusted to required numerical value.The forward voltage that the output voltage of DC/DC transducer equals LED adds the FB end voltage, if led array is formed 4 LED of each Lu Gonglian by 20 road parallel connection LEDs, then output voltage adds the product of the quantity of the forward voltage of four LED and LED for the FB end voltage. drive current can calculate by following formula:
