How does the solar street light controller control the time?
2020 / 10 / 17
The solar street light controller is an important part of the solar street light. It has serial communication data transmission function, manages the charge and discharge of solar street lights and remote intelligent control, and can control the time of solar street lights on and off. But many people don't know how to control the time of solar street lights when using solar controllers. The technician Wang from the solar street light manufacturer below tells everyone this principle. . The solar street light controller can control the two things: the time when the street light is turned on and the duration of keeping the light on. Usually, the solar street light controller does not have a built-in clock, and it does not have a built-in clock. The lighting time is usually triggered by monitoring the current value generated by the solar panel. The current value is usually set to 5ma. Using the solar panel's use time, you can adjust this value accordingly. The new solar street light controller supports multi-time adjustment and control. The lighting power of LED lamps can be set in different time periods and should be adjusted according to actual needs. The adjustment time of each solar street light controller is different. It has an infrared interface, a dedicated data line, and can adjust the network through the network. The best solution is to let the supplier help you before leaving the factory. Complete the operation. Generally, the solar street light controller does not have a built-in clock, and it usually does not operate according to the clock. The lighting time is usually triggered by monitoring the current value generated by the solar panel. The current value is usually set to 5ma. Using the solar panel's use time, you can adjust this value accordingly. The new solar street light controller supports multi-time control. The lighting power of led lamps can be set in different time pe

(Also known as "Silicon Technology") The first issue of the Internet of Things Heroes feature interviews Daniel Russi Netto, co-founder of Brazil Internet of Things-SmartGreen, and rton HESS Jr., R&D director. SmartGreen is a company focusing on sustainable development of smart lighting and smart metering automation solutions. Its headquarter is located in Sao Paulo, Brazil. It works closely with urban and public utility-related services through the use of Silicon Labs' The plan is to deploy 200,000 smart street lights in Brazil by 2022. Although most of SmartGreen's customers are currently located in Brazil, Daniel and Airton shared their valuable insights, especially on the growth drivers that should be seen in municipal lighting and the potential for future smart city applications. Daniel and Airton: SmartGreen was established in 2012 after a merger with another company called RadioTelecom. Now we have 35 employees. From the beginning, our goal was to provide customers with comprehensive IoT solutions, including hardware, communications, gateways, processing layers, and software and applications needed to manage devices. Daniel and Airton: We have two main competitors. In terms of local market competition, although we face competition from some local start-ups, their technology is not as mature as our solutions, and they cannot scale to the level of equipment that SmarGreen can handle. In addition, we also encounter international competitors from time to time, but due to local pricing and technical barriers, these often face challenges when entering the Brazilian market. Daniel and Airton: Compared with our competitors, we can run more devices in our mesh network by using the Zigbee 2.4GHz wireless standard and remain competitive in price. At the same time, we also maintain close contact with our customers. Most of our lighting customers have limited technical knowledge, so they rely heavily
Introduction to LED street lamps and other street lamps lighting power and control methods

Early designs paid more attention to the pursuit of low cost. In the near future, consensus has gradually formed that high efficiency and high reliability are the most important. For example, the electrical equipment capacity of the high pole light pole is 35.4kW, and the lighting power capacity is 66 kW. The power load of the reserved light pole advertising light box, public service advertising box, bus station, traffic signal light, etc. is 161.6kW. The calculated load of the section of electricity is 263kW. According to the requirements of the design specifications and the layout plan of special box transformers for street lamp pole engineering lighting in Wuxiang New District, three box-type substations are set up to supply power to the street lamps. The transformer capacity is 125kVA. The box-type transformer substation is connected to the 10kV line on the nearby road. (Or negotiated by the owner and relevant management departments). A set of street lamp control terminal devices and intelligent power-saving cabinets are installed in the box-type substation. The street lamp control has remote control, time control and manual control methods for street lamp management departments to choose. The box-type substation should be set up in the green belt outside the sidewalk and should not occupy the sidewalk. The street lamp power distribution adopts three-phase four-wire system, each lamp is connected to a 220V power supply, and the loop voltage loss is about 5% to 7%. Metering: A total electric energy metering device is installed in the box-type substation. In addition, in order to measure the electricity load of different electricity prices, the advertising light box has a separate meter. Reserve an advertising light box load of 400W on each street light pole; each bus shelter reserves 5000W of electricity load; every 1000 meters reserves a public welfare advertising light b
What factors influence the price of solar street lamps?

What factors influence the price of solar street lamps? First of all, we need to know what these factors are! So let's talk about what solar lamps are made of. A complete set of solar street lamps should be composed of: lamp pole, light source, photovoltaic panel (solar panel), battery, controller, base cage, wires and screws. Let's start with the solar lamp pole. The price of the lamp pole is affected by the height, wall thickness, arm length and molding process of the lamp pole. The higher the height of the lamp pole, the higher the price, wall thickness, arm length is proportional to the price of the lamp pole. In modeling, the most commonly used humanized arm, self-bending arm, conch arm and S-arm, among which the self-bending arm is on the low side and the conch arm and S-arm are on the high side. Light source yu liang, irradiation range Yu Wide, then its lighting power needs yu, the higher the lighting power price will be higher, the brand of light source chip on the price will also have a certain impact. Now let's talk about photovoltaic panels. At present, photovoltaic panels used by solar street lamps are divided into monocrystalline silicon solar panels and polycrystalline silicon solar panels. The photoelectric conversion rate of monocrystalline silicon solar panels is higher than that of polycrystalline silicon solar panels. Solar street lamp batteries are divided into colloidal batteries and lithium batteries, in the same power, the price of lithium batteries is more than 1 times the colloidal batteries, small power we recommend conditional customers choose lithium batteries, becaus
