RadTech UV+EB 2016 watch exhibition (2)

RadTech UV2016 on May 16, 2016, 18, Chicago, the United States, the participating manufacturers for the industry's most advanced UV curing and sterilization technology professional manufacturers and systems solutions to find manufacturers. This exhibition will be a joint exhibition of professional seminars and exhibitions, RadTech for the industry's UV technology and solutions development indicators exhibition. LEDinside in the exhibition this opportunity and honored to interview Dr. Wu Mingchang vice president of research of crystal photoelectric technology, consult the progress trend of UVLED products and solutions.

Was established in 2005, in the year before the needle for the UV LED products continue to improve technology, such as optical strength and packaging materials and the suitability of the UVLED optical and system design. 2015, with the development of technology and market, emphasizing the application of the market to optimize the optical design, to achieve uniform parallel light effect. In 2016, the study of the main four flagship crystal UVLED products, PCB exposure equipment, ink printing, as well as UV-CLED products to provide a number of product lines UV LED suppliers.

Product one: customized UV COB LED module

(Customized UV COB LED Module)

For high-speed printing and laminating machine screen mobile phone market research, crystal launched quartz glass optical design and copper substrate, UVCOBLED module, UV LED mixed with different wavelength (365nm-415nm), and according to the customer required wattage seamless splicing module in 50-100mm, the working distance of high degree, the single module radiation intensity can reach 2-8W/cm2.

Product two: less than 3 degrees angle UVLED optical design

(UV LED System:Less than3 Optical)

UVLED exposure machine has been very difficult, mainly because the optical design of UVLED is not easy to achieve parallel light. There is a way to light the mercury lamp through the glass tube bypass, into a parallel light, LED light bypass will continue to reduce brightness, resulting in unnecessary losses. However, the introduction of UVLED crystal optical design, the use of special two optical design, can also be achieved at less than 2 degrees of parallel light, more uniform optical design, is quite suitable for PCB/LCD/IC exposure machine. In addition, this product is designed to introduce new equipment into the application, has been successfully introduced into the Taiwan equipment manufacturers and samples sent to Japanese customers. Future research will continue to strengthen the treatment of stray light, making the light not only to achieve uniformity, but also to achieve aggregation.

Product three: water jet pressurization system

Years of experience in optical design, and consulting to end customers, while the development of water cooling system. With the current water cooling system has the problem of temperature and heat exchange efficiency, also led to the overall cooling system performance problems existed for many years. Research and development of cooling system with active crystal, ejector, the cold water in the inner tube, the cold water through hole through the water pressure stable to hot water injection zone to temperature effect, and the stable away heat source, to achieve the overall curing efficiency.

Product four: UV-CLED products

UV-CLED is optimistic about the broad potential of UV-C market in air purification, water purification, food preservation, and medical bacterial inhibition, the introduction of the market to increase the degree of market demand for packaging products. At present, the use of international manufacturers of chips, the future does not rule out the use of Taiwan recommend supply chain products. Research crystal said that the current package has overcome the difficulty of UV-CLED packaging, and has a fairly perfect glass plating technology, product reliability and stability withstand market testing.

Research with own crystal packaging technology: copper substrate and quartz glass optical design, UVLED has become the first brand in the Greater China region in 2016, at the same time combined with heat treatment and electrical supporting patent program, actively expand to the world market.

LEDinside view:

UV-CLED is mainly used in four aspects: first, air purification, air conditioning sterilization; second, drinking water purification and water sterilization; third, refrigerator food preservation; fourth, inhibit the growth of bacteria, the medical market has a large market potential, but the products need to be certified by FDA.

UV LED energy breakthrough, coupled with product life improvement, cost reduction, will be able to drive the UV-C market demand.
