940 infrared LEDs have become an integral part of modern technology, offering a range of applications from consumer electronics to industrial automation. This article delves into the world of 940 infrared LEDs, exploring their characteristics, applications, and the industry trends that have shaped their growth.

Introduction to 940 Infrared LEDs

940 infrared LEDs, also known as near-infrared LEDs, are a type of light-emitting diode that emits light at a wavelength of 940 nanometers. These LEDs are widely used in various applications due to their unique properties, such as high brightness, low power consumption, and long lifespan. The 940 nm wavelength falls within the near-infrared spectrum, making it invisible to the human eye, which is a crucial factor in many applications.

Characteristics of 940 Infrared LEDs

One of the primary characteristics of 940 infrared LEDs is their high brightness, which allows them to be used in long-distance communication and imaging applications. These LEDs have a luminous intensity of up to 100,000 mcd, which is significantly higher than that of other infrared LEDs. This high brightness is achieved through the use of advanced semiconductor materials and sophisticated manufacturing processes. Another important characteristic of 940 infrared LEDs is their low power consumption. These LEDs operate at a forward voltage of around 1.2 to 1.5 volts and a forward current of 20 to 30 mA, making them highly energy-efficient. This low power consumption is particularly beneficial in battery-powered devices, as it helps to extend the battery life. In addition, 940 infrared LEDs have a long lifespan, typically ranging from 50,000 to 100,000 hours. This long lifespan is due to the use of high-quality materials and the absence of harmful substances, such as lead and mercury, in their manufacturing process.
