There are kinds of power available in IR LED. Today we mainly discuss about the IR LED with 850nm wavelength.
The 850nm LED chip directly affects the power of an LED. The power consumption of an LED is determined by the efficiency of the LED chip.
The efficiency of an LED chip is measured by the amount of electrical energy it converts into light energy.
LED chips with higher efficiency convert a larger proportion of electrical energy into light energy, resulting in a brighter light output for the same power input. This means that LEDs with more efficient chips require less electrical power to produce the same amount of light as LEDs with less efficient chips.
Additionally, LED chips with higher efficiency generate less heat for the same light output. This is important as excess heat can reduce the lifespan and performance of an LED. Therefore, LED chips with higher efficiency not only consume less power but also have better thermal management, leading to improved overall performance and longevity of the LED.
0.06W, 0.2W, 0.5W, 1W, 2W, and 3W are power ratings for infrared (IR) LEDs emitting at a wavelength of 850nm. We will package the 850nm LED chip with different size of package according to their power so that they can got a perfect performance in the heat dispersion. Such as 3838 SMD LED, 3535 SMD LED, 2835 SMD LED for high power LED chip. And 3528 SMD LED, 5mm LED, 3mm LED for small power LED chip. These LEDs are used for various applications such as remote controls, security cameras, night vision devices, and proximity sensors. The power rating indicates the maximum power that the LED can handle without getting damaged. Higher power LEDs generally emit brighter and more intense infrared light.
