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.
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.
