What are the Different Types of Security Lighting?

The intelligent lighting control system uses advanced electromagnetic voltage regulation and electronic induction technology to monitor and track the power supply in real time, automatically and smoothly adjust the voltage and current amplitude of the circuit, and improve the additional power consumption caused by unbalanced loads in the lighting circuit.

The intelligent lighting control system uses advanced electromagnetic voltage regulation and electronic induction technology, and uses public lighting unified grid intelligence as a platform to monitor and track power supply in real time, automatically and smoothly adjust the voltage and current amplitude of the circuit, and improve the unbalanced load in the lighting circuit. The additional power consumption, increase the power factor, reduce the operating temperature of the lamps and circuits, and achieve a lighting control system that optimizes the purpose of power supply.

The intelligent lighting control system outputs an optimal lighting power to the lamp under normal operating conditions, which can reduce the lighting glare caused by overvoltage, make the light emitted by the lamp softer, the lighting distribution more uniform, and can greatly Save electricity , intelligent lighting control system can save 20% -40%. Intelligent lighting control system, which can be used in lighting and hybrid circuits, has strong adaptability, can work continuously and stably under a variety of harsh power grid environments and complex load conditions, and will also effectively extend the life of the lamps and reduce maintenance costs.

According to different working situations, the intelligent lighting control system is divided into two types: single-phase and three-phase ^[1]

1. One grid full two-line intelligent lighting control system.

1. Automation of lighting

The biggest feature of the system is scene control. There can be multiple lighting circuits in the same room. After adjusting the brightness of each circuit to achieve a certain lighting atmosphere, it is called a scene. Different scenes can be set in advance, and the fade-in and fade-out time when switching scenes can The light changes gently. Clock control. Use the clock controller to make the lights change according to the daily sunrise and sunset or regular changes in time. Use various sensors and remote control to achieve automatic control of lights.

2. beautify environment

Indoor lighting uses scene changes to increase the artistic effect of the environment, creating a sense of three-dimensionality and layering, creating a comfortable environment, which is beneficial to people's physical and mental health and improves work efficiency.

3 Extend lamp life

The main factors affecting the life of the lamp are mainly overvoltage use and cold shock, which greatly reduce the life of the lamp. LT series intelligent dimmer has output voltage limiting protection function: that is, when the grid voltage exceeds the rated voltage 220V, the dimmer automatically adjusts the output to within 220V. When the bulb is cold-connected, an inrush current of 5-10 times the rated current will be generated, which will greatly affect the life of the lamp. The intelligent dimming control system adopts slow-on and fade-in and fade-out dimming control, which can avoid cold impact on the lamp and prolong the life of the lamp. The system can extend the life of the bulb by 2 to 4 times, which can save a lot of bulbs and reduce the workload of replacing bulbs.

4 Energy saving

The brightness sensor is used to automatically adjust the intensity of the light to achieve energy saving effects. Using motion sensors, when people enter the sensor sensing area, the light gradually rises, and when people walk out of the sensing area, the light gradually decreases or goes out, so that the "changming lights" in some corridors and corridors are controlled to achieve the purpose of energy saving. For example, in order to save power, a hotel replaces all corridor lights with 5W energy-saving lamps to reduce energy consumption. However, the problem is that the energy-saving lamps have poor lighting comfort and reduced illumination, which reduces the hotel's grade. A motion sensor control is recommended.

5. Illuminance and consistency of illuminance

The illumination sensor can be used to keep the indoor light constant.

1. The system can control any loop to continuously dim or

Connotation of intelligent lighting control system

The voltages in different parts of China vary, so when designing various lamps, in order to meet their own normal startup and lighting under different conditions, the design voltage is generally lower than the standard phase voltage of 220V; and the power system is often convenient for power transmission Increasing the transmission voltage causes the actual working voltage of the lighting fixture to be high. These excess voltages not only do not allow the luminaire to work more efficiently, but also have two major negative effects: wasting electricity and shortening the life of the luminaire.

Aiming at the fatal flaw of the existing lighting circuit, Dr. Powell's DL series intelligent lighting power-saving control system uses electromagnetic induction to optimize the input voltage of the power supply system, uses AC-AC direct conversion technology to adjust the voltage, and outputs the voltage to the lighting load. Design the optimal value of voltage for the luminaire, which not only saves electricity, the intelligent lighting control system extends the life of the luminaire, but also guarantees the triple purpose required by the lighting standard.

According to the basic principles of electricians, P = U2 / R, suppose the voltage applied to the lamp is U, and the impedance of the lamp is set to a fixed value resistance R, then the power it consumes at the original voltage U0 is P0. After appropriately reducing the voltage to U1, at this time The consumed power P1 will decrease with the square of the voltage. Its active power saving rate is expressed as: % = 1-(U1 / U0) 2 × 100%.

As far as fluorescent lamps are concerned, sufficient rated voltage is required only at startup to excite the fluorescent substance to cause the lamp to emit light. In the preset time , after the intelligent lighting control system senses that the power of the lamp has been fully exerted, it automatically adjusts the load voltage, and the lamp can be switched to the power saving mode. The intelligent lighting power saving control system also enters the automatic online detection state at the same time. . According to a large number of experimental results, when the power supply voltage is reduced by 10%, the illuminance of fluorescent lamps is only reduced by about 7%, and the perception of light by the human eye is logarithmic: that is, when the illuminance of light is reduced by 10%, the visual perception of humans is only It is reduced by 1%, so the slight change in illuminance caused by a reasonable reduction of the input power of the luminaire is almost invisible to the human eye. The intelligent lighting control system has a positive significance in extending the life of the luminaire and reducing maintenance costs.

Smart Lighting Control System Requirements

1.Humanized and intelligent management

This requires a relatively high-quality user experience and system integration of software and hardware integration. On the hardware, using ZigBee wireless technology, combined with GPRS (or 3G / 4G) technology, to achieve close-range ZigBee operation, long-distance GPRS control, and a combination of distance and distance communication methods, you can be thousands of miles away, as if you are within easy reach between. In software, it is highly integrated with scalable functions, including basic requirements (lamp switch), extended requirements (current, voltage, and power factor detection), innovative requirements, and flexible composition. It not only meets the lighting needs, but also can expand more functions and bring better user experience.

2.Energy saving and environmental protection

The intelligent lighting control system must conform to the current concept of energy conservation and environmental protection, because lighting has always been a large consumer of urban power consumption. If energy demand and environmental protection are to be guaranteed again, it is a problem that must be solved. The emergence of intelligent lighting control systems has solved this problem. More cities use replacement energy-saving lamps, hoping to solve this problem, but with the large-scale expansion of cities, there are more and more lamps, which cannot be solved fundamentally, but the use of intelligent control systems can solve this problem. Realize secondary energy saving on LED lamps. LED supports dimming function. Intelligent lighting control system can adjust and control the lamps according to the time period or according to requirements, and can achieve single lamp control and multi-lamp control of the lamps. Energy saving. And because LED is an environmentally friendly product, it can be guaranteed not to pollute the environment. After data comparison, the use of intelligent lighting control systems can save electricity on a large scale. ^[3]
