The uv-led cross-industry innovation and application conference, organized by the institute of electronics and optoelectronics systems of the Taiwan institute of industrial technology and the federation of optoelectronics industries of Taiwan, will be held on June 16 at the nankang exhibition hall in Taipei.

LEDinside ng: the UV LED market will be worth $356 million by 2020

TrendForce's LEDinside research associate Daniel ng said he expects the UV LED market to be worth $356 million by 2020. Uv-a LED products are mainly used in the photocurable market, and many products are used to increase the market demand. It is estimated that the market value of the UV LED module will reach 532 million usd in 2015.

Current applications include Food Packaging, Food Packaging, Wood Coating (Wood Coating), plastic material curing (Adhesive Coating), Medical curing (Medical Coating), etc., and there are a lot of light curing application market, are emerging period and growth period, looking forward to market to take off. However, the market challenge lies in the high degree of customization, by working closely with the manufacturer of the curing machine, from the wavelength of the chip, the optical module design, the combination of UV glue and the cooling system, to provide the equipment manufacturer complete solution.

Uv-c LED applications include the field of sterilization and purification, the market size potential is huge, and the product profits are considerable, Japan, the United States and South Korea are being developed. At present, uv-c LED technology still needs to be broken through, and product efficiency, life and market acceptance still need to be tested by the market. Expect the development of uv-c LED technology and the implementation of mercury lamp ban regulations, the market prospect will not be underestimated, and expect to become the main growth momentum in the future market.

Professor taijiaotong dahong ruihua: improving the efficiency of light extraction and then improving the external quantum efficiency is the main development direction for manufacturers at present

Professor hong ruihua, from the department of electronics of Taiwan jiaotong university, said that the improvement of the optical extraction efficiency (LEE), and then the improvement of the external quantum efficiency, is the main direction of the current development of manufacturers. UV LED products need to overcome the loss of total reflection of light, increase the efficiency of light extraction, increase the reflector, remove the sapphire substrate, and etch on the surface of n-type emitting light layer, so as to make the best treatment of GaN's problem of absorbing UV light.

Many applications of uv-c LED, including medical analyzer, water purifier, air & surface sterilizer, surface & medical sterilizer, air purifier, household appliances sterilization, etc. Uv-c LED, which is produced by the crystallization photoelectricity, can be seen to have sterilization effect on escherichia coli and staphylococcus aureus after being irradiated for 5 minutes by 265nm, 3mW products and 40mm working distance.

'uv-c sterilization is quite obvious, especially for superbugs such as MRSA, Clostridium Difficile, Acinetobacter Baumannii, vancomycin-resistant Enterococcus,' said huang zhengchuan, research and development department of dingzhong co., LTD. Music, Aspergillus Niger and others can kill 99% of bacteria.

The design of uv-c product still needs to consider the main wavelength, radiation illumination, radiation energy, security, etc. At present, uv-c sterilization products can be seen in portable, public places, industrial production areas and so on. However, to import uv-c LED into the application, market acceptance is of great importance to product price and security.

UV LED has the characteristics of high technical content, high product competition, easy differentiation, and relatively scattered customer area and high degree of customization. It is a niche market worth laying out for LED manufacturers in Taiwan.

With the driving force of rapid progress of LED technology and price, the UV light source, which has been widely used in various traditional industries and science and technology, has been introduced into the UV LED light source with advantages of energy saving, long life, small volume, fast point-out speed and environmental protection without mercury, and has gradually gained advantages and market feasibility.

For example, the market of ultraviolet LED has expanded from recognition of banknotes in the past to the light resin hardening, insect catching lamp and printing industry, and further developed to the highly technical deep ultraviolet germicidal function, medicinal plants and other market USES.

And deep ultraviolet UV -c LED (200 ~ 280 nm) and UV - B LED (280 ~ 315 nm) no matter in epitaxial threshold than uv-a (315 ~ 380 nm) is much higher, and the encapsulation cooling capacity requirement is high, the packaging technology and material choice requires special consideration, in order to meet the designed for UV LED in both the sterilization, water treatment, medicinal plants and other application products needs.
