History of LED 5mm UV

The concept of UV light dates back to ancient times when people observed that certain stones could produce a glow when exposed to sunlight. However, it was not until the 19th century that scientists began to study UV light and its various applications. The invention of the UV LED in the 1990s marked a significant milestone in the history of UV lighting technology. Over the years, LED 5mm UV has gained popularity due to its numerous advantages over traditional UV sources.

Technology of LED 5mm UV

LED 5mm UV is a type of solid-state lighting device that emits UV light with a wavelength between 380 and 400 nm. The core component of this LED is a semiconductor material, usually gallium nitride (GaN), which emits UV light when an electric current passes through it. The following are some key aspects of the technology behind LED 5mm UV: - Material: The most common material used in LED 5mm UV is gallium nitride (GaN), which has excellent UV emission properties. Other materials, such as zinc selenide (ZnSe) and silicon carbide (SiC), are also used in some applications. - Structure: The structure of an LED 5mm UV consists of a p-n junction, where the p-type and n-type layers are separated by a thin layer of GaN. This structure allows for efficient conversion of electrical energy into UV light. - Efficiency: LED 5mm UV is highly efficient, with an electrical-to-optical conversion efficiency of up to 30%. This means that a significant portion of the electrical energy is converted into UV light, resulting in lower power consumption and longer lifespan. - Color and Intensity: The color and intensity of UV light emitted by an LED 5mm UV can be adjusted by altering the composition of the semiconductor material and the thickness of the p-n junction.
