History of LED 850nm

The development of LED technology dates back to the early 20th century. However, it was not until the late 20th century that LED 850nm became a significant player in the market. The first LED 850nm products were introduced in the late 1990s, primarily used in medical, industrial, and military applications. Since then, the technology has rapidly evolved, and its applications have expanded to consumer electronics, automotive, and other fields.

Technology of LED 850nm

LED 850nm refers to the wavelength of light emitted by an LED, which is 850 nanometers. This type of LED emits infrared light, which is invisible to the human eye. The key components of an LED 850nm are the semiconductor material, the encapsulation material, and the lead frame. The semiconductor material is typically made of gallium nitride (GaN) or aluminum gallium nitride (AlGaN), which can emit infrared light at 850nm. The encapsulation material is used to protect the semiconductor material and enhance its performance. Common encapsulation materials include epoxy, polyimide, and silicone. The lead frame is used to connect the LED to the circuit board and provide electrical conductivity. The manufacturing process of LED 850nm involves several steps, including epitaxy, wafer slicing, chip bonding, and packaging. Epitaxy is the process of growing a thin layer of semiconductor material on a substrate. Wafer slicing involves cutting the epitaxial wafer into individual chips. Chip bonding is the process of attaching the chip to the lead frame. Finally, packaging involves encapsulating the chip and lead frame with the encapsulation material.
