UV LEDs represent Ultraviolet Light-emitting diodes. This Led generates Light in the VU spectrum that is actually less than 400 nm. UV light can be seen with naked eyes and is usually found in color bluey purple.
These LEDs light-generating diodes, which are solid-state equipment, generate Light when electrical current is permitted to flow from the positive terminal of the circuit to the negative side. These LEDs are manufactured to generate a definite narrow range of Ultraviolet wavelength.
They are compact, do not contain toxic substances, and are inexpensive. The current market situation of LEDs depends on their wavelength. The rapid development of the short UV wavelengths (between 280 nm and 100 nm). They exist in the range of various packages, such as surface mounted or through-hole. The viewing angle shows the angle at which the Light is produced. However, narrow and broad beams exist to package various applications. Different VU lights are available in the market with definite designs.
Type of Vu led Light.
- VU led technology has emerged as an important choice for a variety of different applications are as follows:
- They are used in industrial curing
- Cosmetic curing
- Use in forensic analysis
- Security system
- Sterilization
- Plant growth
A lifetime of VU Led light
In conclusion, Phoseon’s rigorous reliability, hard work, and lifetime guarantee of light sources have exceeded 60,000 hours of operation in the specified time with light source irradiance. It is larger than 80% of its standard output when the test started more than five years ago.
Differences between traditional UV lamps and UV led sources
Traditional arc lamps make use of an electric arc in the inner side of the mercury gas to alert atoms which then spoil and produce photons. Microwave lamps excite the gas through a microwave emitting process. At the same time, UV LEDs semiconductors produce a narrow bandwidth of energy at the junction. In order to dope semiconductors, positive holes integrate with negative electrons when voltage is applied.
These LEDs are manufactured in a wide range of power levels and come in single chip-on-board, strip, and complete light source module forms. The majority of these products are available in bulk. However, the costs are higher for lower wavelengths. This is because the semiconductors in the lower wavelengths are more expensive than those in the upper UVC range. The use of ultraviolet LEDs in air-purification systems, for example, requires a higher aluminum mole fraction.
Benefits of Vu Led Lights
The first major issue with traditional VU lamp light is the availability of mercury. As we know, mercury has great environmental consequences; it is a very cost-effective, worldwide mercury-free solution considered a potential research area. Whereas the original VU lamps contain around 20-200mg of mercury, and UV light doesn’t exist. When making a comparison with the traditional lamps, the Light consumption and heat production of UV LED bulbs are significantly less. Mostly VU Led light technology is used in the UV curing segment. UV curing is a method deploying a high-density ultra-light wave that is used to immediately dry and cure coating inks.
