[OPIE '17] LED specializes in UV LED and infrared optical 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 was fortunate to interview Wei Zhihong, general manager of crystal, sharing the current research in the field of UV LED and infrared LED technology trends.

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 one: 270nm- 270nm UV-C LED products used in 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.

Currently UV-C LED product wavelength has been able to do 270nm-275nm based, 10mW @ 150mA products have been completed to send samples and small shipments, the third quarter of 2017 and the fourth quarter more new products have been launched. 20mW product development has been completed, is expected to send samples to customers in the third quarter, the fourth quarter will be completed 30mW products. 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 observation, compared to other manufacturers using high current drive to improve the light output. We use low current products to control the heat in the acceptable range and improve the market application.

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

Crystal said that the use of infrared LED quartz glass, the use of primary optics in the shape and appearance of the surface of a unique design, the light source can be effectively concentrated, the plane light evenly on the face, to determine. As a result of a lens design is quite complex, technical threshold is high. At present, the thickness of the product can reach 2.4mm and 1.6mm, so the thinner product is more suitable for camera module manufacturers and brand manufacturers to design, the current infrared LED products have been imported into the notebook computer market. Under the mass production in the future, the cost can be reduced effectively, in order to provide customers with more cost-effective products.

Product three: UV-A LED for fast 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 the optical module, the study of crystal close partners MITSUBISHI enterprises to take advantage of the subsidiary, to provide cooling solutions partners, but also to develop a crystal in the Japanese market agents.

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.
