The current expectations of led street light control
Lighting is certainly one of the fundamental aspects of the “Smart Cities” project where technologies will merge to give rise to a future more sustainable, efficient, and environmentally friendly “smart cities”.
In order to solve many led street lights problems, use Intelligent Street Lighting Systems, it’s all computerized, and all you have to do is set the desired time.
Remote management, remote diagnosis, LED lighting, electric vehicle charging stations, widespread video surveillance, home automation, and broadband wi-fi Internet are the technologies that will play key roles in the innovation process of our cities.
Intelligent lighting controller, also known as programmable lighting controller, that is, the lighting program of the controller can be modified according to the needs of the user, such as modifying the speed, time, pattern, synchronization, and asynchrony of the light flashing.
Intelligent Street Lighting Systems turns on the street lights every night at nightfall. Street lighting in cities provides safer traffic conditions and a safer pedestrian environment. And Intelligent Street Lighting Systems can significantly improve the architectural, tourist, and commercial output of a city. And Intelligent Street Lighting is more affordable and less costly to maintain.
It also allows flexible, individual controls to replace inefficient timers. With the intelligent street lighting system up and running at all times, most lighting problems are detected and solved before the public even has a chance to notice them.
By dimming unnecessary lights and diverting power from faulty equipment, it can significantly reduce energy consumption. An intelligent light is switched on and off automatically by a system that automatically switches off lights and senses pedestrians and vehicles. This saves on wasted electricity to a large extent. Thus saving the cost of LED street lights. It also immediately reduces energy costs by up to 35% through intelligent on/off switching, targeted progressive dimming, and efficient consumption management. This means that intelligent light also automatically senses the light intensity of the environment and adjusts the brightness automatically.
Cutting public spending linked to energy users, by improving and innovating infrastructures, will make it possible to create new jobs by being able to use those resources saved in other projects of public interest.
Easy to maintain
Intelligent street lighting enables the computer to report faults in real-time, speeding up maintenance work. Maintenance teams no longer need to patrol the streets. They are notified in detail of any faults. Intelligent lighting systems send a detailed analysis of street lighting defects and necessary materials to the maintenance staff’s computers. This solves most led street lights problems. The lighting system is compatible with IOS and Android. This ensures that you get a real-time web map, a list of street lights, and access to the system’s functions. Even if you are traveling fast, intelligent lights can capture the sensations in time.
The defects of time control only
The advantage of time control is that according to the time of sunrise and sunset, the lights are basically on when it is dark, and the lights are off when it is bright. The disadvantage is that it is cloudy and rainy, and the street lights cannot be automatically turned on when the light is insufficient. The seasons change with time, from the winter solstice to the summer solstice, the light on time gradually postponed, the light of time gradually advanced. During the transition from the summer solstice to the winter solstice, the time of turning on the lights is gradually advanced and the time of turning off the lights is gradually delayed, so human beings are still unable to ensure the weather changes in each time period. Changes in the weather can change the time of darkness/dawn. This may result in the fact that it is already dark and the lamp is not turned on, or that it is already daylight and the lamp is not turned off. A waste of energy in a way, this is an LED street lights problem that needs to be solved. On sunny and rainy days, ON and OFF times differ noticeably which is one of the major disadvantages of using timer circuits for switching the street light system.
What is a photocell?
Photocell is also named daylight sensor or dusk to dawn sensor, its on/off standard is the illumination value of the position of the street light. The light is automatically turned on and off by sensing the illumination value of the surrounding.
The defects of daylight control only
The advantage of light control is that it can determine whether the street lights are on or not according to the strength of the light on the road. Sometimes even in the daytime, it will be caused by cloudy and rainy days, and the road luminance is low. At this time, the street lights will be on to meet the lighting requirements. The disadvantage is that because there is a lot of dust on the road, it is easy to cover the surface of the photosensitive element that receives the signal, making the signal inaccurate.
The combination of time control and daylight control
The intelligent control system of street lights is combined with time and space and light control. In the time range of sunrise and sunset, when the illuminance meets the requirements of switching lights, the system will automatically send instructions to switch on and off the street lights. Using advanced control technology, the fusion light control function and the ordinary time controller have a large number of functions as a whole. According to the user’s energy-saving needs, the light control probe and the time control function can be activated at the same time, which will achieve the best energy-saving effect.
Daylight control and time control mode, which can turn on the lights during heavy rain and foggy weather during the day, and turn off the lights in the middle of the night at night.
It is the best energy-saving control device for street lights. It can be widely used in streets, railways, stations, waterways, schools, power supply departments, and other applications that require time control and light control.
The scientific principle of photocell
The principle of light control is to use photocells, photoresistors, and other photosensitive elements. That is, when the light intensity irradiated on the element changes, its related parameters: current flowing, resistance value, etc. will change accordingly. A collection of components that detect this change in the photosensitive element and use it to control other systems is called light control.
The conditions of LED street light with photocell
Both DC LED street lights and AC LED street lights can be installed with a photocell. When the person wants the street light to be turned on/off automatically, photocell is a good choice.
LED street light with photocell needs to be installed with a receptacle/base such as 3 pin Nema socket, or 5 pin Nema socket, or 7 pin Nema socket or other bases.
