Introduction to LED Wavelength Options

LEDs, or Light Emitting Diodes, are semiconductor devices that emit light when an electric current passes through them. The color of the light emitted by an LED is determined by its wavelength, which is measured in nanometers (nm). LED wavelength options refer to the different colors of light that can be produced by LEDs, ranging from ultraviolet (UV) to infrared (IR).

Types of LED Wavelengths

LEDs come in various wavelengths, each producing a different color of light. Here are some of the most common LED wavelengths and their corresponding colors: - Ultraviolet (UV) LEDs: UV LEDs have a wavelength range of 380-450 nm and are used in applications such as curing adhesives, sterilization, and UV curing of inks and coatings. - Visible Light LEDs: Visible light LEDs have a wavelength range of 380-780 nm and are used in various applications, including general lighting, display screens, and medical devices. - Blue LEDs: Blue LEDs have a wavelength range of 450-495 nm and are used in LED TVs, mobile phones, and other display devices. - Green LEDs: Green LEDs have a wavelength range of 495-570 nm and are used in traffic signals, medical devices, and general lighting. - Yellow LEDs: Yellow LEDs have a wavelength range of 570-590 nm and are used in automotive lighting, traffic signals, and general lighting. - Orange LEDs: Orange LEDs have a wavelength range of 590-620 nm and are used in automotive lighting, traffic signals, and general lighting. - Red LEDs: Red LEDs have a wavelength range of 620-750 nm and are used in automotive lighting, LED TVs, and medical devices. - Infrared (IR) LEDs: IR LEDs have a wavelength range of 750-3000 nm and are used in remote controls, wireless communication, and medical devices.
