UVLED industry application and prospect analysis, the development of UVLED led vacuum oven sales!

Introduction: in recent years, UVLED curing technology has attracted worldwide attention. In many application fields, uv-led light source has gradually replaced the traditional mercury lamp light source.

Uv-led is a kind of electroluminescent diode, compared with the traditional UV mercury lamp, more environmental protection, high efficiency and low energy consumption, is a truly sustainable green industrial technology.

1. Single wavelength, high luminous efficiency and low energy consumption

Uv-led can directly convert electric energy into UV light, and emits single-band ultraviolet light. The energy of light is highly concentrated in specific ultraviolet light bands. Now, there are mature applications in such bands as 365nm, 385nm, 395nm and 405nm in the market.

However, the emission spectrum of conventional UV mercury lamps is very wide, and the UV spectrum segment with effective curing effect only accounts for a part of it. Meanwhile, the photoelectric conversion efficiency is low and energy consumption is high.

2. No infrared ray and ozone

Traditional mercury lamp will produce infrared ray, and give out a lot of heat, easy to cause damage to the heat sensitive substrate.

Uv-led is a cold light source, which can effectively avoid the shrinkage and deformation of the substrate due to overheating, and has a wider adaptability to the material.

Uv-led, which is also used for UV curing, is usually ultraviolet light with a longer wavelength, so no ozone will be generated during the curing process, and it can maintain a good working environment, which is safer and more environmentally friendly than traditional mercury lamps.

3. Spot and light, electronic control

Uv-led does not need to be preheated like mercury lamps, nor does it need to be kept on at all times to maintain tube life and efficiency.

Uv-led can instantly turn on (off) the light, the output energy can also be set freely, and can automatically adjust with the machine speed, very energy-saving, simple and convenient control.

4. Long service life and low maintenance cost

The service life of uv-led lamp can reach more than 10,000-50,000 hours, more than 10 times that of conventional mercury lamp, and the light attenuation is very slow, the service life is not affected by the number of switches.

At the same time, the LED light source has no mercury and no accessories such as lampshades, so it needs little maintenance, reducing the maintenance cost.

5. High flexibility and small system size

Uv-led light source can be divided into point light source, line light source, surface light source, can be customized effective illumination area.

The size of the light source equipment is small, and the irradiating device and related supporting devices are very compact, which does not need the large mechanical installation space and pipeline construction in the past.

This feature enables it to adapt to a variety of production processes, the production process is more efficient.

According to TechNavio, the uv-led market has been growing at a very high rate for the last seven to eight years, from $20 million in 2008 to $90 million in 2014, with a compound annual growth rate of 28.5%.

In 2016, due to the active introduction of uv LED products into various applications such as curing, sterilization and purification market, the estimated output value will reach $166 million, of which the market value of LED application in curing will reach $81 million.

By 2020, the global uv-led technology market will grow at a compound annual rate of 3.9 percent.

In 2015, the uv-curing market accounted for 48.14% of the uv-led technology market.

The printing industry has increased the demand for uv-led curing equipment, and the greatly improved flux density for uv-led chips has made uv-curing occupy a large part of the uv-led technology market. Meanwhile, printing industry has developed into a large user of uv-led curing equipment.

Uv-led technology has achieved great success in the field of inkjet, which promotes the application of uv-led technology in the whole printing industry.

Uv-led technology for the Asian market

European uv-led technology will grow from $36.28 million in 2015 to $190.2 million in 2020.

Environmental regulation of hazardous substances and a ban on mercury lamps in Europe have made the European market an important contributor to the global uv-led market.

Because uv-led is environmentally friendly and USES less electricity, it has a large number of applications in the medical, adhesives and printing curing markets in Europe, and these applications have become a major factor in the growth of the European market.

Uv-led technology for the north American market

Uv-led technology accounts for 26.8% of the north American market.

TechNavio forecasts that the north American uv-led technology market will grow from $34.33 million in 2015 to $179.06 million in 2020.

Due to the rapid growth of the market, the graphic arts industry in North America is increasingly using uv-curing equipment and technology.

Other uv-led uv-curing applications involve the healthcare industry, communication equipment industry, automotive industry, building materials industry, etc.

Since uv-led is a single-band UV light source, the initiator absorption spectrum needs to be matched with the LED emission spectrum. Currently, there are not many initiators developed for LED light source in the market, and those that can be mass produced are even more scarce.

Therefore, the matching of initiators has always been the difficulty of LED photocuring. Currently, the available photoinitiators include TPO, tpo-l, ITX, DETX, BAPO, etc.

However, these initiators do not have very strong absorption peaks at 365nm, 385nm, 395nm and 405nm, so the initiation efficiency is not high.

At the same time, compared with the traditional mercury lamp, its power is low, the irradiation energy is not high, especially the ink color system, if the printing speed lead to ink curing not thorough given initiator compatibility and equipment power of these two issues, for the LED curing light curing resin, you must have very high reactivity, to avoid adverse curing, etc.

Few uv-led curable resins currently available on the market are subject to the two major issues of reactivity and stability.
