Talking about UV LED Wavelength and application

Wavelength classification and application fields of ultraviolet light According to the different biological effects, ultraviolet rays are divided into four wavelength bands according to wavelength: long-wave UVA, medium-wave UVB, short-wave UVC, and vacuum UVD. The longer the wavelength, the greater the penetration.   UVA Long wave UVA, with a wavelength ranging from 320 to 400 nanometers, is also known as long wave black spot effect ultraviolet radiation. Has strong penetrating power, able to penetrate glass, even up to 9 feet of water; And it exists throughout the year, regardless of whether it is cloudy or sunny, day or night.   Harm to human body: More than 95% of the ultraviolet rays that daily skin comes into contact with are UVA, so it causes the greatest damage to the skin. UVA can attack the dermis through the epidermis, causing severe damage to collagen and elastin in the skin; Moreover, dermal cells have poor self-protection ability, and a small amount of UVA can cause great harm. Over time, the skin develops problems such as looseness, wrinkles, and the appearance of microvessels.   At the same time, it can also activate tyrosinase, leading to immediate melanin deposition and the formation of new melanin, making the skin black and lacking luster. UVA can cause long-term, chronic, and long-lasting damage, leading to premature aging of the skin, hence it is also known as aging radiation.   Application field: UVA ultraviolet radiation with a wavelength of 360nm conforms to the phototactic response curve of insects and can be used to make insect traps. UVA ultraviolet rays with wavelengths of 300-420nm can pass through specially colored glass tubes that completely cut off visible light, emitting only near-ultraviolet light centered at 365nm. They can be used for ore identification, stage decoration, currency verification, and other places.

What is UV LED light curing system?

What is UV LED light curing system? What are the characteristics of UV light curing? In recent years, UV LED light curing technology has received close attention from the world, and many industrial production fields are gradually choosing UV LED light sources to replace traditional UV mercury lights. The UV LED light curing technology is environmental friendly that realizes the concept of environmental sustainability through use of light emitting diodes. Compared with the traditional UV mercury lamps, it has more higher efficiency and low energy consumption. Following are a few features of UV LED light curing:   1. The characteristics of the UV LED light source are that it belongs to a single-band ultraviolet light, with high luminous efficiency and low energy consumption. The UV LED light source can convert electrical energy into light energy through the led chip, and can emit a single-band ultraviolet light source. 365/385/395/405nm these bands. Compared with the traditional UV mercury lamp, only a small part of the full-band ultraviolet light emitted can actually exert energy efficiency. At the same time, the mercury lamp will generate a large amount of heat energy when it is in use, resulting in a large amount of energy consumption to a large extent;   2. UV LED light curing belongs to a kind of "cold light source", which does not generate infrared band and emits a lot of thermal energy, thereby causing thermal damage to the surface of the substrate. Like some ink printing fields, chip processing, liquid crystal display packaging and other fields, UV LED light sources are basically used for product processing;   3. The UV LED light curing system adopts a unique control panel, which can be used immediately when the power is turned on. It does not need to be preheated in advance like the traditional mercury lamp curing, and there is no need to worry about the regular replacement of consumables due to the life of the lamp like the mercury lamp. . UV LED light curing can instantly light up the lamp beads, and the power (10-100%) can be adjusted at will, which not only saves energy, but also is easy to operate!   4. The maintenance cost of UV LED light source is low. Usually, the use time of a UV LED curing machine is about 25000h, which is 5-8 times that of traditional UV mercury lamp. Due to the life of the lamp beads, almost no maintenance is required, which effectively reduces the cost of equipment maintenance;   5. The UV LED light curing system is mainly divided into UV LED spotlights, UV LED line light source, UV LED surface light source, UV LED curing lamps, UV LED water cooled machine, etc. according to its use environment, and the luminous size and irradiation can be customized according to the actual working conditions Area, the irradiation position is matched with the equipment, no large-scale machinery and pipeline installation are required, it can be adapted to work in a variety of environments, and the work efficiency of the assembly line is improved.   6.

UV LED System Lifetime

Long LED UV System Lifetime   Solid-state Light Emitting Diodes (LEDs) produce light when an electrical current flows from the positive (anode) side to the negative (cathode) side. Like other solid-state devices, LEDs offer a long lifetime if used properly. If engineered correctly, these semiconductor devices last beyond 20,000-30,000 hours of operating time unlike traditional UV lamps. Traditional lamps produce light by generating an electric arc inside an ionized gas (typically mercury) chamber to excite atoms, which then decay, emitting photons. Additionally, the European Commission (EC) through its Restriction on Hazardous Substances (RoHS) guidelines has continually monitored the rapid progress of UV LED’s capability. Many in the industry predict the EC will begin limiting traditional lamp usage, starting first with smaller systems then working towards larger systems in ensuing years .Combining energy generation of today’s UV LED light sources and the right formulation of UV curable resins, photoinitiators, and additives, it is possible to surpass current process capabilities for a variety of applications. UV LEDs are one small, though important, part of a UV light source, but the rest of the system must also be taken into account when discussing the lifetime. This includes the internal control circuitry plus the cooling system to ensure the LEDs remain within their operating specifications, as well as the housing to protect the LEDs from environmental factors. Yuanming’s patented and proprietary systems use thermal management, sealing techniques, optical enhancements, and control circuitry to maximize performance without sacrificing lifetime. UV LED Technology Benefits   Factors Affecting LED Lifetime Two major factors that affect the lifetime of LEDs are temperature and current. As LEDs convert electricity into light, heat generates within the p-n junction, known as the junction temperature. For a diode to achieve maximum life expectancy, the junction temperature has to remain in a safe operating zone. The UV Power output of a diode increases with input current but decreases with junction temperature. At any fixed input current, the cooler the junction temperature remains, the more UV output the diode will provide.     LED End of Life Characteristics The normal ‘failure mode’ of an LED is gradual degradation of the light output. Many commercial LED lighting systems define failure at 70% of the original operating output, also known as L70. Yuanming lamp sources are designed to ensure an L80 lifetime (80% of original output) of at least 20,000-30,000 hours, but have shown to provide L80 at as much as 40,000 hours.

How to Increase the Efficiency of LED UV

How to Increase the Efficiency of LED UV Led uv is a type of printing technology that uses UV rays to create images on a variety of different materials.led uv It is a versatile technique that is perfect for many different applications. In addition to its versatility, led uv is also energy efficient and environmentally friendly. Unlike traditional printing technologies, LED UV does not produce any heat, making it safe to use in most environments. This makes it a great choice for commercial and industrial settings. LEDs have the potential to replace traditional UV lamps in many applications.led uv They are smaller, more compact, and consume less power. Additionally, they do not require any warm-up time and turn on instantly when switched on. They also do not contain mercury, which can be harmful if released into the environment. As a result, LEDs are a safer alternative to mercury vapor lamps for water purification systems. In addition to their superior safety features, LEDs have a lower operating cost than other UV sources.led uv They also have a longer life span than traditional bulbs. This is important for any business that wants to save money and reduce maintenance costs. LEDs are a great alternative to mercury vapor lamps and are an excellent choice for any UV curing application. Currently, LEDs in the 280 nm +-5 nm wavelength range have a relative wall plug efficiency (WPE) of 4.led uv 1% and an external quantum efficiency (EQE) of around 6.1%. The WPE is a measure of the amount of energy that is converted to light. The EQE is the percentage of the input electrical power that is turned into radiation.led uv The higher the EQE, the more efficient the LED is. However, the EQE of an LED depends on a number of factors including the manufacturing process, device geometry and packaging material. In order to improve the EQE of UV LEDs, a number of strategies have been explored. One method that has been successful is to use a silicon-nitride substrate with p-type and n-type layers.led uv The p-type layer is formed with a high concentration of Al, while the n-type layer is made of SiN. This combination provides an effective band-gap of 3.4 eV and a low Schottky barrier height. Another way to increase the EQE of UV LEDs is to reduce the thermal resistance of the device.led uv This can be achieved by using a thermally conductive epoxy and reducing the contact surface area. It is also possible to use a hemispherical lens on the LED die to eliminate the recombination defect in the p-type layer. In addition, it is important to use a low refractive index packaging material such as PDLC. Tags:405 uv led module 3d printer | 405nm uv led module 3d printer

There are many ways to create braille signage - laser and rotary engraving, photopolymer, cast metal, or raster Braille (spheres/beads inserted into drilled holes). But these processes take a lot of time and can be expensive, especially for large orders. Using a flatbed UV printer to create braille signage can be fast, cost-effective, and highly effective - especially when you add in-house production capabilities for ADA-compliant signs. One of the most popular applications for UV printing is creating ADA-compliant signage. With direct-to-substrate UV printing, custom UV LED Sign fabricators can easily print second-surface graphics and logos as well as grade 2 braille lettering. This can save a great deal of time over traditional methods of creating ADA signage, such as adding raised pictograms to existing signs. Another reason why UV printing has become a popular option for ADA signage is that it can actually save fabricators money in the long run. Because the printing process occurs directly on the substrate, there is no need to apply additional materials such as a top laminate or glass covering. This reduces overall sign fabrication costs and allows shops to offer their clients a more budget-friendly option. In addition to saving money on materials, UV printing also makes it easier for fabricators to produce ADA signage quickly. Using the direct-to-substrate method, it is possible to create a 6x8 sign with a full ADA-compliant display in less than four minutes. This means that sign fabricators can meet deadlines and keep their clients happy by delivering their services on schedule.

Benefits of Using a UV LED Lamp for Printer

Benefits of Using a UV LED Lamp for Printer The global printing industry is worth almost a trillion dollars and growing rapidly.for uv led lamp for printer uv But traditional print equipment based on mercury lamps is losing share to new digital UV LED printers. A key reason for this is the much lower electricity consumption of UV LED systems.for uv led lamp for printer uv Like for like a full-width UV LED array only uses about half as much power to operate as a metal halide lamp at the same output level, with the remainder going to the output control circuitry and cooling fan. And of course LED arrays generate no heat and produce no ozone, so there is also less need for ventilation. It's even possible to use much smaller LED arrays.for uv led lamp for printer uv This makes the total footprint of a machine much smaller and it is becoming common for manufacturers to fit them into their new wide format printers without major modification. For example, Integration Technology Ltd in the UK launched a new range of lamps at FESPA this year that are just a direct replacement for their existing mercury lamp units used on head carriages in wide format printers. As well as consuming significantly less power, LEDs don't heat up the printed substrate or the media so it is possible to use heat-sensitive materials that would be impossible to print with mercury lamps.for uv led lamp for printer uv This opens up many new revenue opportunities for commercial printers and can reduce costs for converters who have to buy expensive heat-resistant film or paper stocks. Another benefit of using LEDs is that the printers do not need to run at high speeds, which helps to keep the power consumption down.for uv led lamp for printer uv And fewer start and stop cycles of the LED lamps increases their service life, which in turn reduces maintenance cost over the lifetime of the machine. Industrial UV LED curing uses water-based inks and adhesives, which are free of solvents and eliminate the release of volatile organic compounds (VOCs). This can greatly reduce environmental impact compared to conventional inks and adhesives. Unlike traditional mercury arc lamps, which operate at full power all the time, LEDs are more efficient at varying output levels and so can be operated at a lower voltage, further reducing energy use. They can be used to cure non-porous surfaces and even 3D objects, with the help of special optical systems that disperse the energy over a larger area. The low operating and maintenance cost of UV LEDs enables printing companies to increase productivity and profitability without having to invest in new machinery. They can also operate in remote locations where access to power is limited or unavailable. And because they don't emit infra red or radiant heat, LEDs are a good choice for use with heat-sensitive materials, such as vinyls and films, that can buckle or warp when exposed to normal mercury arc curing light.
