• ‌850nm infrared LED Chip : This kind of lamp bead is widely used in surveillance camera, digital shooting, apartment intercom, anti-theft alarm and infrared waterproof and other fields. Its brightness is high, and the price varies depending on factors such as brightness, wavelength consistency, luminous Angle, and antistatic ability. In addition, 850nm infrared LED Chip can also be used in beauty and medical devices and other fields ‌.
• ‌940nm infrared LED Chip ‌ : Compared with 850nm, 940nm infraredLED Chip does not appear visually visible red dots when working, so it is more suitable for applications that need concealability, such as controllers, controllers of household electrical products, etc. At the same time, it is also widely used in infrared monitoring, infrared sensing and remote control and other products.

940 LED Chip introduction

• Basic features ‌ : The 940 LED Chip is an LED Chip with a wavelength of 940 nanometers (nm), which belongs to the infrared spectral range and is invisible to the human eye. It has compact structure, small size, light weight, and high luminous efficiency and service life.
• ‌ Application scenario ‌ : Since the infrared light of 940nm is invisible, the 940 LED Chip is widely used in the occasions that need to be hidden, such as the infrared surveillance camera, shutter remote control, smart home, UAV, infrared heater and so on in the security system. In addition, the 940 lamp bead can also be used as a remote control for position locking.
• ‌ selection points ‌ : When selecting the 940 LED Chip, we should pay attention to the brand reputation, wavelength purity, luminous Angle, power, current and voltage and other parameters to ensure that it is suitable for specific application scenarios.
• ‌ advantage ‌ : Compared with 850nm infrared LED Chip, 940 lamp beads do not appear visually visible red dots (that is, red explosion phenomenon) when working, so it is more suitable for applications that need concealability.
