Smart led street lights with day light sensor day light automatic dimming
The day light sensor module needs to be used with the dimming module.
Different from manual switch dimming and the use of induction modules, it can realize automatic dimming of the system, high efficiency and energy saving, suitable for offices, factories or warehouses;
To preset the required illuminance value of the environment, the sensor can sense the current illuminance of the daylight and automatically issue a dimming instruction.
The dimming power can be used to adjust the brightness of the light, intelligently fill the light, and maintain the constant ambient illuminance while achieving energy saving and cost
The illuminance value is preset when there are people passing and when people are not passing.
The sensor can sense the movement of the human body within the range of the device, determine whether it is passing state, automatically issue a dimming instruction, and adjust the brightness of the light through the dimming power.
“status quo” and “future trends” of smart street lights with day light sensor
The city has a large number of street lights, which is the most dense urban infrastructure and facilitates the collection and release of information. The future of smart street lights is an important source of information collection for the Internet of Things. Urban smart street lights are an important part and an important entrance of smart cities.
- Smart street lights are the best entrance and service port for smart cities
Smart street lights are an important part of smart cities. It uses city sensors, power line carrier / ZIGBEE communication technology and wireless GPRS / CDMA communication technology, etc., to connect street lights in the city in series to form the Internet of Things, to achieve remote centralized control and management of street lights. Conditions and other conditions setting scheme automatically adjusts brightness, remote lighting control, active failure alarm, lamp cable anti-theft, remote meter reading and other functions.
Smart street lights can effectively control energy consumption, greatly save power resources, improve the level of public lighting management, reduce maintenance and management costs, and use information processing technologies such as computing to process and analyze massive amounts of perceptual information, including information on people’s livelihood, the environment, and public safety. The various needs within the city make intelligent response and intelligent decision support, so that urban road lighting reaches a “smart” state.
- What functions does a smart street light have?
From a lighting perspective, what functions should be covered by a smart (energy) street light?
1. Remotely measure electrical parameters such as current and voltage of street lamps, remotely switch on and off street lamps, and remotely monitor on-site operation of important road sections.
2. Monitor the temperature of the samrt LED street lamp chip pads or the temperature of the lamp housing and fault diagnosis.
3, daylight sensor or vehicle-induced dimming, as well as time control or even RTC dimming in energy-saving control.
4. According to the lighting monitoring data, timely grasp the location of the abnormal street lights and the cause of the abnormality, and carry out inspections purposefully instead of going to the city for inspection, which speeds up the maintenance speed and reduces the maintenance costs.
5. The lighting standard level on the same road changes with time and traffic flow into a variable value. For example, the brightness of some newly developed roads may be lower at the beginning of traffic. After a period of time or by monitoring the traffic flow to reach a certain threshold, turn on the full light. .
6. In some sparse areas of people and cars, it can be controlled at half-time in the middle of the night, but when people and cars pass, they reach a certain distance in front and are fully bright, and the rear restores the original brightness after a few seconds, and so on.
- Frequent policies and vigorous promotion of smart lighting
With the widespread application of next-generation information technologies such as the Internet of Things, next-generation Internet, and cloud computing, smart cities have become an inevitable trend. In recent years, new policies of smart cities have frequently appeared, and many cities in China have set off a climax of smart city construction. The government has issued a series of policies and measures to promote the construction of smart cities. As an important part of smart city construction, smart street lights are expected to receive policy support in the future.
As an infrastructure, street lights have the characteristics of orderly distribution, extensive coverage, and electricity in the city. If it is only used for lighting, it obviously does not give full play to its value. Therefore, when the multi-pole integration and the demand for 5G micro base stations became clear, the smart light pole suddenly caught up with the air outlet, and received strong policy promotion and incentives.
- The smart street light pole has become a “generalist”, and the functions of 5G micro base stations are remarkable.
At present, as an indispensable infrastructure for urban development, smart light poles already have features such as power supply, networking, and widespread distribution. Not only as a data collection terminal, but also as a data terminal, it integrates surveillance cameras, 5G micro base stations, security alarms and other hardware, and realizes functions such as intelligent lighting, smart transportation, wireless cities, and information release through information perception and big data interaction technologies. .
Among them, 5G micro base station functions are remarkable. The report released by the American Association for Wireless Communications and International Networks (CTIA) states that urban street lights will be an important infrastructure in the 5G era. This report believes that densely distributed 5G small base stations are the key foundation of smart cities. Municipal and regulatory agencies should streamline the approval process and adjust the charging structure to encourage telecommunications operators to make full use of urban infrastructure such as street lights and poles to build 5G networks.
- Multiple shots are costly, and a mature business model needs to be established
A smart city cannot be just a tower in the air or limited to small-scale test scenarios. The benefits of 5G brought about smart networking and urban transformation are visible and can be expected. It also needs to be matched with 5G technology and a mature commercial operating environment in order to obtain rich returns.
Smart lighting must have 3i features. The first is to use sensors to sense the state of all objects and the environment to realize perception. For more thorough perception, surveillance cameras, sensors, RFID, data centers, data mining and analysis tools, mobile and handheld devices, computers and multimedia terminals in the lighting environment provide a variety of rich external data.
Smart street lights are the product of industrial division of labor. LED modules, WIFI / micro base stations, monitoring, single light controller and other modules, all have mature manufacturers. It is almost impossible for an enterprise to complete the development and manufacture of all modules. Professional division of labor and modular design are the only way for mature industrial products.
Multifunctional (smart) street lights are actually carriers for information collection, processing and distribution. Multi-functional street lights can bring about the need to save land, integrate resource utilization, and enhance the significance of the city’s image. At the same time, standardization of modules, diversified styles, and professional configuration are the future development directions of multifunctional street lights.
- The construction of smart cities is advancing steadily, and the demand for smart dimming street lights is expected.
As an important part of smart cities, smart street lights have also been highly valued and vigorously promoted by relevant departments. At present, with the acceleration of the urbanization process, the purchase volume and construction scale of urban public lighting facilities are increasing day by day, forming a huge purchase pool. However, the contradictions in urban lighting management that have emerged are becoming increasingly apparent. The three most prominent contradictions are the huge consumption of energy, excessive maintenance costs of lighting fixtures, and incompatibility with other public equipment. The emergence of smart lighting will undoubtedly change this status quo and effectively promote the acceleration of the process of smart cities.
Day light dimming Street lights are an indispensable public carrier for urban lighting and one of the “facades” about the public image of a city or region.
Although the concept of smart lighting is very popular and has been applied worldwide, Guangzhou, Hangzhou, Dongguan, and other places in China have also launched smart lighting renovation projects for LED street lights, but their applications in many cities are not widespread. The application department’s awareness of this technology and application is relatively lagging. For example, is the technological level of smart lighting systems fully mature? How can smart lighting systems be integrated and compatible with other urban management systems? How can the social effects and actual values of smart lighting complement each other? These issues have also seriously affected smart lighting Extensive promotion and application in cities.
