Description
Technical field
The present invention relates to a kind of light-operated LED road lamps that power factor elevated operating temperature is low.
Background technology
LED street lamp used at present, power factor are all very low.The low utilization meaned to power grid electric energy of power factor
It is low, increase the power supply cost of power supply department；Street lamp uses master switch centralized control, once control switch breaks down, then opens
Lamps and lanterns in photocontrol all extinguish.
Invention content
A kind of light-operated LED road lamp that material gain rate factor elevated operating temperature is low of the present invention, designs the light-operated switch of dispersion in each
In a street lamp body, street lamp auto-open-close lamp is allowed；The power factor of LED street lamp is set to be up to 0.91 or more using efficient circuit, and
Operating temperature is maintained at 40 DEG C hereinafter, the electric energy that LED street lamp is absorbed from power grid is allowed to be made full use of；Keep the work of LED street lamp
Make temperature at 40 DEG C or less, the service life of LED street lamp can be made to have ready conditions and reached 50,000 hours.
A kind of light-operated LED road lamp that power factor elevated operating temperature is low, circuit composition by power circuit, light-operated circuit,
Timer circuit, PWM modulation circuit and LED lighting board circuit composition.
Description of the drawings
Fig. 1 is a kind of circuit diagram for the light-operated LED road lamp that power factor elevated operating temperature is low.
Specific implementation mode
As shown in Figure 1, IC1 and outside for element form power circuit, the model single-phase bridge rectification heap of IC1, select 1A
The above capacity, C1, C2 are safety capacitors, and L1, L2 are differential mode inductance, and L3 is common mode inductance, C3, C4, D2, D3, D4, R1 composition
Valley fill type power factor correction circuit can be effectively improved harmonic distortion and power factor.Power circuit input AC 220V power supplys, output
The DC voltage and power factor of stable about 300V reach 0.91 or more direct-current power supply next stage circuit.
As shown in Figure 1, IC3 and peripheral cell form light-operated circuit, base counting chip when the model 555 of IC3, R11 is
Photo resistance.On daytime, light irradiates resistance, so that its resistance value is compiled small, and 2, the 6 foot electricity of IC3 are to increase, when voltage is raised to 2UCC/3
When, 3 feet of IC3 export low level, so that relay JS is in stop working state, LED street lamp does not work；When the evening draws on, R11 is electric
Resistance lacks the existing irradiation of light, and resistance value increases, and acting on current potential at 2,6 feet of IC3 reduces, when voltage drop the to UCCWhen/3, IC3's
3 feet are high level by low transition, and effect relay JS is attracted, and normally opened contact J1 is closed, and connects rectifier IC1 circuits,
Again by other related circuits, keep LED street lamp bright, realizes light-operated switch function.
As shown in Figure 1, IC4 and outside for element form timer circuit, the model CD4060, R2 of IC4 are dropping resistors,
300V DC voltages are reduced into about 20V supplies filtering, regulator circuit, it is work electricity to export stable 12V DC electricity supply IC2
Source.C14, R14 that 12 feet of IC4 are external are electrifying self-resetting circuits, when IC4 obtains the moment of working power, electrifying self-resetting electricity
Road is exported to 12 foot, one positive pulse signal of IC4, and effect IC4 internal circuits are reset, and 3 foot of drive output exports low level
Signal, effect triode T2 become being connected from ending, and driving relay JB is attracted, and normally opened contact J3 is closed, and connects PWM modulation
The output load current value circuit of circuit, at this point, LED street lamp is operated in vehement bright work condition state；In street lamp continuous work, one sets
After part is count down to when definite value, 3 feet of timer IC4 become high level output from low level, and effect triode T2 is become from being connected
Cut-off, then relay JB becomes tripping from being attracted, and normally opened contact J3 is disconnected, and normally-closed contact J2 is closed, and connects PWM modulation circuit
Output setting dimmed power state circuit, at this point, LED street lamp is operated in light modulation work condition state.
As shown in Figure 1, IC2 and peripheral cell form PWM modulation driving circuit, base counts core when the model 555 of IC2
Piece, the size of the dutyfactor value of the external element decision PWM modulation of 2,6,7 feet of IC2.It is changeless in R5, R6, R7 resistance value
Under the premise of, the size of duty ratio is controlled by the normally opened contact J3 and normally-closed contact J2 of the output relay JB of timing control circuit.
When normally opened contact J3 is closed, 3 feet of IC2 export big dutyfactor value, and effect LED street lamp is operated in vehement bright work condition state
In；When normally-closed contact J2 is closed, 3 feet of IC2 export small dutyfactor value, and effect LED street lamp is operated in dark bright operating mode shape
In state.Timing is set by timer control circuit as needed, to realize automatic dimming function.
As shown, LED is luminescent screen circuit, use monolithic power for the LED chip with Zener diode function of 1W,
Circuit is connected as being connected in series with all the way, and the work(to reduce LED street lamp makees total current, reduces the operating temperature of LED street lamp, connection
LED string quantity is selected as needed.
As shown in Figure 1, V is varistor, anti-lightning strike lamp transient overvoltage protection is played in circuit, B is fuse, and E is
The thermistor of negative temperature coefficient plays Antisurge current, R2, R3, R4 current-limiting resistances in circuit.
