For most manufacturers, they have a lot of sapphire substrate suppliers. The main manufacturers are DOWA, Rayvioand Bioraytron.
UV-B LED is applied in ink curing, phototherapy, plant growth and food preservation. According to the requirements, product power and irradiance intensity have to rise continuously.
The technical threshold of UV-C LED is high. There are many challenges whether in the production of substrates, crystal growth, epitaxial growth, chip structure design and packaging techniques.
Increasing LEE and EQE are the main factor.
In terms of packaging techniques, limiting factors include how to achieve vacuum SMD packaging to reach economies of scale and how to define the performance indicators in simulation test.
If GaNepitaxy is lower than 365nm, light may be absorbed. Adopting AlN/ AlGaNepitaxy can increase brightness.
In the future, if it reaches 265nm, the material may be changed due to limitation.
UV-C LED product technical thresholds mainly include substrates, epitaxial growth, chip structure design, packaging and measuring.
LED chip technology faces two major challenges, one of them is raising the External Quantum Efficiency (EQE).
In terms of chip techniques, there are flip chip or vertical chip structure. Currently, to pursue brightness, UV LED manufacturers gradually introduce vertical chip technology.Vertical chip accounts for % of UV-C LED market.
LG Innotekadopts flip chip structure for products below mWand adopts vertical chip structure for products above mWto produce UV-C LED chip. Reducing the use cost of submountcan achieve better price-performance ratio.
DUV LED products focus on the increase of EQE. There are three main factors: IQE, EE and LEE.
Thus, to rise EQE, LEE has to be increased first, which is the key developing factor.
Because UV-C LED scatters the light and reduces efficiency, metal reflection layer is adopted to increase luminous efficacy. Currently, this technique becomes the mainstream on the market. Many major manufacturers adopt this method.
Products of XXX have been marketed. In the beginning of 2018, LG Innotekindicated their product can reach 100mW and it is expected to be released in 2018. According to LG Innotek'sproduct plans, XXX can be achieved in June 2018 and XXX can be achieved at the end of 2018.

The supply chain of UV curing market includes UV LED chip, UV LED package, UV module and system (contain cooling system) and UV resin.
UV LED module is vulnerable to the risk of disabled LED: UV LED module in series often causes the failure of the entire module resulting from a single damaged LED, currently it is still unable to avoid this problem, and only the method is available to add module design warning light when designing module to reminder system manufacturers that the current UV module cannot be cured and it is under damage control.
The above list is about UV curing module and system manufacturers. The main demands come from Europe, America, Japan and China.
According to RadTech, UV curing equipment applications include coating, offset printing and printing markets.
According to 2016 UV LED Curing Community and LEDinside's2017 market condition, each curing demand in 2018 will grow continuously.
Sheet-fed Offset features with high-speed paper feeding, and it is necessary to set aside enough space for paper feeding, as UV LED technology improves, its irradiance has gradually met the market demand, so that UV LED in sheet-fed offset application achieves increasing market demand.
Flexography is widely used in packaging industry, featuring with high-speed printing, strong pressrun and easy operation, which has become one of the applications achieving rapid market demand growth, also the demand for UV LED curing module has increased yearly.
Currently, to maintain high technology entry barriers, manufacturers shift their focus to the high-speed printing market monopolized by global companies and leading printing equipment providers. Although the overall revenue of printing equipment slides on an annual basis, yet the current LED penetration rate remains relatively low, compared with those in other curing markets; plus the market shows a demand to replace old equipment, hence the confidence in future market growth. As the labor cost in China has increased in recent years, the market is anticipating an increasing demand for automation from PCB makers. LEDinsidekeep an eye on the shipment of automatic exposure equipment.
Top five major printing equipment manufacturers around the world are Heidelberg, KBA, Komori, Ryobi and manroland. Air Motion Systems (Baldwin Technology Group) is a famous UV LED modules and systems manufacturer in the world and has entered the OE supply chain of the above major printing manufacturers.

The above list is about UV curing module and system manufacturers. The main demands come from Europe, America, Japan and China. European and the US manufacturers consider price-performance ratio and mostly adopt the UV LED chips of LG Innotekand Seoul Viosys. Owing to the increasing demand, European and the US UV curing module manufacturers started to appoint Taiwanese UV LED manufacturers to produce UV LED products.
UV-B LED is applied in ink curing, phototherapy, plant growth and food preservation. According to the requirements, product power and irradiance intensity have to be increased continuously.
In terms of phototherapy market, the products of Philips Lighting are the most developed. It has the widest range of product specifications. Besides PUVA, BB UV-B and NB UV-B are involved, as shown in the above table.
Dust mite is a contagious allergen. Its secretions, excretions and polypideare allergen, which cause allergic rhinitis, asthma, eye irritation, atopic dermatitis and urticaria. Bedding is a natural harbor of dust mite. It is available to use mite cleaner for removing the dust and mite on bed sheet, quilt cover and pillow cover besides high-temperature washing.
The mite cleaners in the market, flapping 4000-7000 per minute and featuring with UV tube, can achieve sterilization efficacy of 99% -99.9%.
Manufacturers adopt 253.7nm traditional mercury lamp at present, and some manufacturers have gradually switched to UV LED. With the BAF approval standards, it is possible to confirm the effective removal of mites, pollen, fungi, dust and animal hair.
For the long-term goal, UV-C LED is expected to be used in medical sterilization, printing and curing, and water treatment. In accordance with application requirements, the power and the irradiance of products need to be continuously improved.
According to the data from Water. org, up to 2018, 844 million people in the world don't have access to safe water and 2.3 billion people lack access to improved sanitation like a toilet. More people have a mobile phone than a toilet. Every 90 seconds a child dies from a water-related disease, and the leading cause of child death is diarrhea. 1 Million people killed by water, sanitation and hygiene-related disease each year.
In the countries lacking access to safe water, women need to spend 6 hours a day to collect water. This also means that local women cannot pursue skills outside of their traditional roles and experience greater autonomy and independence. The water crisis is a health crisis. Access to safe water and sanitation means opportunity for improved health and the ability tohelp fight disease. Access to safe water means reduced child and maternal mortality rates. It means increased dignity and reduced psychological stress for girls and women. It means reduced physical injury from constant lifting and carrying heavy loads of water. And it means reduced risk of rape, sexual assault and increased safety as women and girls do not have to go to remote and dangerous places to relieve themselves.
