Specific embodiment

In the embodiment in figure 1, we for implementing a kind of LED energy-conserving road lamp of timing darkening to the utility model into One step explanation:

Fig. 1 is a kind of LED energy-saving street lamp circuit schematic diagram of timing darkening of the utility model, we are a fixed to make It is described in detail for the LED energy-conserving road lamp of Shi Bianguang, zero line 1, zero line side 2 are common 220V supply terminals in figure；It is whole Stream bridge 3 is high-voltage rectifier bridge, and internal structure is four rectifier diodes, can as four independent rectifier diode effects To select 600V or 1000V, 2A large chip patch full-bridge, the anode of rectifier bridge output is supplied to the filtering of filter capacitor 4, rectifier bridge Cathode output be defined as being grounded in the present embodiment；Filter capacitor 4 connects between anode and ground, is high-voltage filtering capacitor, can To choose the patch electrolytic capacitor of 15uf, pressure resistance 450V；Constant current integrated circuit 1, constant current integrated circuit 26 select SM2082 line Property constant current chip, M2082 is single channel LED constant current drive control chip, chip use constant current setting and control technology, output electricity Stream is set as 5mA-60mA by outer connecting resistance, and exports electric current and do not change with chip OUT terminal mouth voltage, has preferable constant current Performance, system structure is simple, and peripheral cell is few, low in cost, and 1 foot of SM2082 is output pin, and 2 feet are grounding leg, and 3 feet are It exports electric current and foot is set, naturally it is also possible to other linear constant current chips, such as SM2087, SM2083, TH1000A etc. are selected, as long as It is the linear constant current chip by resistance adjustment continuous current, can be implemented using the embodiment of the utility model；Timing mould Block 7 selects one piece of timing module, and resistance is arranged indirectly, is reserved with the position of pin resistance and Chip-R for 1 foot, 2 feet of the module It sets, 3 feet are supply pin, and 4 feet are output pin, and 5 feet are triggering foot, and 6 feet are grounding leg, connect the DC voltage of 2-5v in 3 feet and 6 feet Module can work normally, which has multiple businessmans to provide in Taobao, and need to only search for fixed " timing module " can choose, should There are four time setting multiplying power contacts to be not drawn into for module, can choose 64 times of setting, and timing module power supply current-limiting resistance 8 is selected 400K Chip-R, timing module power supply voltage-stabiliser tube 9 select the patch voltage-stabiliser tube of 2.7v, and timing module, which is fixed time, is arranged resistance choosing It can be delayed 7 hours with the Chip-R of 1.5M, constant current integrated circuit current setting resistance 1, constant current integrated circuit electric current The Chip-R that resistance 2 12 selects 20 Ω is set, is connected to LED light bead string between lamp bead string positive terminal 13, lamp bead string negative pole end 14 15, LED light bead string is using 2835 liang and 80 strings.Its working principle is that: when power supply is connected, due to the triggering of timing module 7 Foot 5 is grounded, and 7 timing of timing module starts, and 4 feet export low level, constant current integrated circuit current setting resistance 1, constant current collection It is all equivalent to ground connection at circuital current setting resistance 2 12, constant current integrated circuit 1, constant current integrated circuit 26 work at the same time, LED light bead string 15 shines, and 18 watts of Maximum Power Output or so, when timing is 7 small after, be equivalent to midnight, road pedestrian When rare, 4 feet of timing module 7 export high level, and constant current integrated circuit 26 stops working, and then flow through LED light bead string 15 electric current is mainly that constant current integrated circuit 1 provides, and the power of LED light bead string 15 is about 9 watts, realizes the mesh of using electricity wisely , second day repetition this process.18 watts are a small street lamp, Yao Zengjia power, it is only necessary to increase constant current integrated circuit, It is in parallel using multiple constant current integrated circuits.
