What are the requirements for the operation of the controller for solar LED street lights?

Solar LED street light is a new energy-saving and environment-friendly lighting equipment in recent years. It uses inexhaustible solar energy in the natural world to generate electricity, and combines its advantages with LED lighting. The goal of achieving common lighting between LED and solar energy is to realize the power generation that is not restricted by the mains. It is an advanced lighting device that combines LED Light Source and solar energy. So what are the requirements for the operation of the controller for solar LED street lights?

The actual operation of the solar LED street light controller, the general solar street lamp manufacturers will set up and debug the controller before leaving the factory, realize the external access parameters on the debugging solar LED street lighting system, and implement intelligent unattended work. status. In order to fully meet the working requirements of the LED light source, the set parameters will be written into the data flash memory of the solar controller. Let the controller control the entire solar LED street lighting system from time to time. Moreover, the solar panel is also charged to the battery through the solar controller during charging to meet the nighttime operation of the lighting device.

At the same time, when the battery is performing voltage collection, the controller uses the PWM function to manage the charging of the battery. Open circuit protection for the battery. If the solar panel is charging normally, the controller will turn off the load to ensure that the load is not damaged. If it is not charged at night or when the solar panel is not charging, the controller will lose its instinct and there will be no signs of any action.

The solar LED street light controller can be used for battery reverse connection, over charge, and over discharge. The load output controls and detects the two load outputs. Each channel of the output has a circuit design of an independent control system to achieve perfect control requirements and perfect overcurrent short circuit protection. With such a controller, the entire solar LED street lighting system can be protected and the service life of the entire device can be extended.

3528 SMD IR LED supplier from China.

There are copper heatsink on the bottom of the 3528 LED, while the 3528 bottom heat sink copper is very small. That's why we only can supply the power within 0.5W for the 3528 LED and can do High Power LED for the 3528 LED.

We produce and sell 3528 SMD IR LED , which is with the wavelength from 680nm-1550nm. In this category, we mainly introduce the two kinds of wavelengths: 940nm IR LED and 850nm IR LED . These two wavelengths are the most commonly used wavelengths in infrared monitoring. They all can be used to monitor products.

Then what is the difference between 940nm LED and 850nm LED ?

940nm infrared LEDs are totally invisible to the naked eye, which means you can't see whether the 940nm working or not. Unless you watch it through some device(like phone's camera), which will show some purple or white color light.

The 850nm infrared LEDs have a very slight reddish when it's working, which means you can see if the 850nm LED is working.

Under the same power, radiation intensity of 850nm will be higher than the 940nm. Of course, 940nm also has its own unique advantages. It is the naked eye that is indistinguishable from work or from work, therefore, its application has been widely used in many special markets in the modern era.

We supply the 3528 940nm SMD IR LED and 3528 850nm SMD IR LED products with difference power, such as: 0.1W 940nm, 0.2w 940nm, 0.3w 940nm, 0.4w 940nm, 0.5W 940nm, 0.6w 940nm, 0.8W 940nm, 0.1W 850nm, 0.2w 850nm, 0.3w 850nm, 0.4w 850nm, 0.5W 850nm, 0.6w 850nm, 0.8W 850nm and so on.
