Intelligent street lamp through the adjustment of the output voltage of the lighting line, reduce the effective current of the light source, in the initial stage of the linear decline of the voltage, the illuminance is not significantly reduced, and the power saving is reduced by the square of the voltage. Intelligent street lamps have the characteristics of high luminous efficiency, low power consumption, long service life, safety and reliability, strong light output of light source, and environmental protection. It is used in urban main roads, urban secondary roads, industrial park roads, urban and rural roads and other fields.

Ideal Power-Saving Controller Model and Electrical, Communication Protocol Specifications Lighting Energy-Saving Controller Load Assumptions:

All inductive ballasts lamps, including inductive-started fluorescent lamps, neon lights, inductive-started mercury lamps, sodium lamps, metal halide lamps, etc.

All resistive load light sources, including incandescent lamps, iodine-tungsten, halogen lamps, etc.

All electronic ballasts energy-saving lamps and electronic ballasts HID lamps.

Inductive ballast luminaires with power factor compensation capacitors, lighting circuits with centralized or decentralized capacitance compensation.

Mixed load lines above the lighting loads.

It is an electronic ballast light source that allows a small amount of power load (step-down and energy saving is not significant), office automation equipment (internal switching power supply automatic voltage stabilization, external step-down cannot save power), and built-in power factor correction (PFC realizes internal voltage regulation).

Rationale. 1.Constant regulation of the output voltage, for high grid voltage (usually 230V on hand combustion, electrode transition damage, high temperature), can realize the protection of lamps, prolong the life of lamps, and also have a large space for power saving.

2.The illuminance of the lighting site is adjusted to meet the environmental protection and green lighting indicators, and at the same time save energy.

3.According to the situation change of the place, "people-oriented", "on-demand brightness", "real-time brightness".

The control circuit of the energy-saving street lamp of the intelligent street lamp is composed of a decoding circuit, an aberasa switch circuit and a transformer control circuit. In order to achieve excellent energy-saving effect in the time-sharing control of street lights, in addition to turning on different levels of voltage according to the time period, it is also necessary to take into account the voltage fluctuations of the grid voltage in different periods. Therefore, the power signal detected by the single-chip microcomputer and the real-time clock chip DS1302 signal processed by the single-chip microcomputer are used as the input terminal of the decoding address of the 74LS155 two-four decoder, and the output of the four ends of the decoder is amplified by the triode to drive the coils of the four vibrato-segment contactors respectively, and the four contacts correspond to the three contacts of the self-lotus transformer, that is, the four gears of the street lamp

Full voltage (220 V), peak (93% of rated voltage), normal (88% of rated voltage), low peak (83% of rated voltage). From the lease of the hole, it can achieve the effect of taking into account the brightness of the street lamp and achieving energy saving. km4 is connected to the bus and the street lights can also be turned off.

The energy-saving system of intelligent street lamp is mainly composed of power detection circuit, real-time clock, autotransformer circuit, display circuit and carrier communication circuit. The year is roughly divided into three seasons to control the street lights, so that they have different times to turn on and off the lights in different seasons. From turning on the lights to turning off the lights, according to the local traffic, it can be roughly divided into three stages (peak, normal, and trough) to control the street lights.

The current working conditions of the street lamp are classified accordingly from the real-time clock chip, and the disconnection of the coil of the contactor is controlled by the output of the single-chip microcomputer, and the output of its contact controls the three contacts of the autotransformer respectively, corresponding to four gears, and each gear corresponds to the corresponding street lamp voltage. Due to the power transmission of harmonic interference caused by power instability, to detect the power of the street lamp at all times, with the power chip ATT7028 to detect the current or voltage is too high or too low, the information obtained is transmitted to the AT89C51 single-chip microcomputer, the single-chip microcomputer and the ferroelectric memory information at the same time, if the current or voltage is found to be too high or too low, the single-chip microcomputer immediately makes adjustments, appropriately reduce or increase the voltage, so as to achieve the street lamp overload, overvoltage and other functions into the hole control, The on-site situation is transmitted to the control room of the auditorium using power carrier communication technology. <>

Energy saving of street light controllers: It can significantly save electrical energy, reduce maintenance costs, and have obvious economic and social benefits, making it an ideal choice for modern outdoor lighting control. The controller has two outputs, the first is the all-night light, that is, the light is on when it is dark and the light is off at dawn; The second way is the mid-night light or the all-night light, that is, the light is on when it is dark, and the light off time can be set by the user, if the user sets the light off time is greater than the light off time of the first road, the road automatically changes to the all-night light.

Users can make some of the street lights stay on at night, and the other part of the street lights are turned off regularly, which not only meets the lighting needs, but also saves electricity.

Street lamps light up the night in our city and provide convenience for everyone. However, so many street lights also consume a lot of energy every year, because China's electricity mainly depends on coal, so the pressure on the environment is also great. Therefore, it is necessary to pay more attention to the energy saving of street lights.

The street light controller is a tool to control the street light switch, which can make energy more efficient by intelligently controlling the opening and closing of the street light.

As long as the user calibrates the clock of the controller, enters the longitude and latitude of the region, the controller can automatically calculate the sunrise and sunset time of different seasons every day according to the law of the earth's rotation and revolution, and realize the automatic switch control of street lamps and related equipment. Users can also fine-tune the time according to the actual situation in their region. It can be widely used in intelligent control of outdoor lighting such as street lights, garden lights, advertising light boxes, neon lights, navigation lights, etc.

The street light controller is not a simple timing switch, but intelligently adjusts according to the local daily sunshine time to achieve the maximum lighting effect with the least energy use. This is the most effective use of a tool.

By controlling the lighting time of the street lamp, it can also effectively extend the service life of the electric lamp, so that it brings greater convenience to the repair and maintenance, and the more serious suspicion is to save a lot of expenses for the municipal department and the contractor, and this part of the funds can be saved and used in a more useful place, which is a good thing to kill two birds with one stone.
