[OPIE 17] research crystal specializes in UV LED and infrared LED packaging technology and optical design, in line with the rapid printing, sterilization and purification market

Research is one of the famous crystal ultraviolet LED and infrared LED manufacturers, with years of experience in close cooperation, specialization and chip manufacturers packaging product development and optical design, combined with the above three major advantages of the development of ultraviolet LED and infrared LED products. LEDinside in OPIE '17 exhibition, had the opportunity to interview Wei Zhihong, general manager of crystal, to share the current research trends in the UV LED and infrared LED technology.

This exhibition, Wei Zhihong said 2017 will mainly research the development of the three crystal product technology solutions, respectively 270nm- 275nm UV-C LED products used in sterilization and purification market, infrared LED applied to iris, face recognition scheme and UV-A LED application in fast printing market.

Product 1: 270nm-, 270nm, UV-C, LED products are applied to the sterilization and purification market

Light hung for ultraviolet and infrared chip manufacturers; research focused on crystal package and module, good deep UV market development, three years ago must actively establish Taiwan deep UV products supply chain. By the end of 2016 light hung and research published crystal products that will be announced for Bioraytron light and crystal Hong research joint venture brands, the establishment of deep ultraviolet LED vertical integration production from epitaxial, chip, focused on the UV-C LED package and related product sales module.

At present, UV-C LED products wavelength has been able to do 270nm-275nm based, 10mW @ 150mA products have completed delivery samples and shipped a small amount, in the third quarter of 2017 and the fourth quarter, more new products have been launched. 20mW product development has been completed and expected to be delivered to customers in the third quarter. 30mW products will be completed in the fourth quarter. Such rapid progress, all rely on light and crystal research Hong mutual trust and cooperation results.

In addition, crystal research said that the current primary market application of locking water purifier in the air purifier and water, using its own unique optical design, developed 60 and 30 degrees of the product, improve the efficiency, to small angle exposure to the irradiation area more and more relative to the market 120 the product space.

Bioraytron will be in the second half of 2017 to launch the second generation UV-B/ UV-C LED packaging technology, will strengthen the overall design combined with optical chip and package mechanism, perfect various optical angle and light, the convenience of customers of different sterilization and skin treatment application more simple design, accelerate the commercialization of popularization

LEDinside observed that, compared to other manufacturers, the use of high current drive to improve light output. Research and application of low current products, thermal control in the acceptable range of customers, improve market applications.

Product two: infrared LED applied to iris and face recognition program

Research crystal said that the infrared LED quartz glass, the use of an optical appearance, shape and surface of a unique design, the light can be effectively concentrated, flat light evenly irradiated on the face, to determine. As a result of a lens design is quite complex, technical threshold is high. At present, the product thickness can reach 2.4mm and 1.6mm, so thin products are more suitable for camera module manufacturers and brand manufacturers to design, the current infrared LED products have been imported into the notebook computer market. In the future, under the mass production, the cost can be effectively reduced to provide customers with more cost-effective products.

Product three: UV-A LED applied to rapid printing market solutions

Compared with the industry by reducing optical module illumination area promotion radiation research program, from the angle of crystal package can reach to 100mm under the radiation of >8W/cm2, not only to format the irradiated area, can achieve accurate quick printing market requirements. At the same time combined with the quartz glass encapsulation, copper substrate, heat dissipation problem, as long as the COB LED client module products a stitching lock screws, can be due to rapid UV printing customers in module 1000-1100mm, or even 2000mm width, the present research has successfully entered the crystal several well-known Japanese printing module manufacturers.

In addition to optical modules, the research and development of close cooperation partners, Yang enterprises for MITSUBISHI subsidiary, providing heat solutions partners, but also research and development agent in the Japanese market.

Finally, general manager Wei Zhihong said, the future will continue to research the crystal is not visible light LED packaging technology and optical design of continuous improvement, the use of quartz glass and copper substrate, the product quality is stable, close cooperation with business partners, to meet the market demand and industry customers.
