In different seasons, the infrared dimming electronic ballast is regulated to time required to delay, which is convenient for the requirements of road illumination and saves electric power.

Description

A kind of infrared dimming electronic ballast
 
Technical field
The present invention relates to electric ballast, especially infrared dimming electronic ballast.
Background technology
The timing dimming electric ballast is applied to road lighting and has obtained good social benefit and economic benefit, the timing dimming electric ballast is to adopt the full power illumination in the bigger period of the flow of people and Che (as 18 point-23 point), reaches the purpose of saving electric energy and reduce lighting power in the less period of (point in 23 o'clock-second day early mornings 6) people's vehicle flowrate in midnight to early morning.This timing dimming electric ballast exists a problem to be exactly, winter and summer are because the time phase difference of darkness is very big, also have than big difference the rush hour of people's activity in night, so use the time with a kind of setting in winter and summer, will make troubles to people's trip and comings and goings.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, provide a kind of not only be applicable to summer but also the winter of being applicable to the scalable timing infrared remote controlled light modulated electric ballast.
Technical scheme of the present invention: a kind of infrared dimming electronic ballast, comprise the EMI filter circuit, the EMI filter circuit connects bridge rectifier, bridge rectifier connects the APFC power factor correction circuit, the APFC power factor correction circuit connects half-bridge inversion circuit, half-bridge inversion circuit connects current-limiting inductance, current-limiting inductance connects high-voltage lamp, high-voltage lamp is connected with firing circuit, described half-bridge inversion circuit is connected with frequency control circuit, frequency control circuit connects timing dimming circuit, and timing dimming circuit is set timing by infrared remote-control device.
Operation principle of the present invention is: input current is through the filtering of EMI filter circuit, be direct current through the bridge rectifier rectification then, pass through APFC passive power factor corrective circuit again, export the half-bridge inversion circuit use of back level altogether of a stable 400V direct voltage, voltage after half-bridge inversion circuit will be stablized through APFC, be changed to high-frequency ac voltage, behind current limit by inductance, use for high-voltage gas discharging light, in the high-voltage gas discharging light start-up course, firing circuit produces 3-4 kilovolt high pressure and lights high-voltage gas discharging light, frequency control circuit changes by the big or small control frequency that detects output current, combination by half-bridge inversion circuit and current-limiting inductance is to export a constant-power power source, timing dimming circuit is set delay time by infrared remote-control device and is outputed to frequency control circuit, the control power output.
Beneficial effect of the present invention is, not only made things convenient for road lighting but also effective saves energy.
Darkness in winter early (general 17 just need to open street lighting), the words of 23 light modulations need be delayed time 5 hours, and darkness in summer evening (turning on light for 19), 23 light modulations only need time-delay 3 hours.
If the light modulation time unification is set at time-delay 4 hours, so in the winter time, put forward previous hour 22 illumination of naming a person for a particular job and turn down, people's car is also many on the road at this moment, and low-light (level) can cause current inconvenience even accidents caused easily.And the light modulation time in summer will postpone one hour, and this hour people's vehicle flowrate seldom, do not need so high brightness, cause energy waste.
The present invention can set different delay times by infrared remote-control device.Adjust to the time that needs time-delay in Various Seasonal like this, both made things convenient for the demand of road lighting, saved electric energy again.
Description of drawings
Fig. 1 is the theory diagram of invention.
Embodiment:
EMI filtered electrical routing capacitance and common mode inductance are formed, the 220V power supply is through EMI filtering, after the bridge rectifier rectification, be adjusted to stable 400V direct voltage by the APFC power factor correction circuit, being converted to high-frequency ac by half-bridge inversion circuit then uses for fluorescent tube after current limliting, half-bridge inversion circuit is made up of two field effect transistor and half-bridge drive circuit, frequency control circuit detects the electric current of half-bridge inversion circuit output, the frequency of the driving of the big or small calculation control half-bridge inversion circuit by detecting electric current, the high-frequency ac frequency of half-bridge inversion circuit output is changed thereupon in proportion, effect by current-limiting inductance makes it to keep permanent power output, timing dimming circuit can be set delay time by infrared remote-control device, present embodiment is set two kinds of delay times: be set at time-delay 5 hours again summer, delay time and begin to export an instruction after 5 hours to frequency control circuit, control circuit is exported control signal after detecting the instruction of timing circuit, the output frequency of control half-bridge circuit raises, and through current-limiting inductance ballast output power is reduced; Be set at time-delay 3 hours winter, delay time and export an instruction after 3 hours to the frequency control circuit light modulation, ballast power is reduced to half-power.
