The new view of blue ocean market: Aotewei, Liansheng optoelectronics focused UVLED vehicle market

The full spectrum photoelectric silicon substrate

Liansheng Optoelectronics (HPO) has the world's first silicon substrate bonding technology and patent, this key technology for wafer manufacturing process, the substrate was originally used in the epitaxial growth of (such as sapphire substrate, GaAs substrate) into the silicon substrate, in order to improve the reliability of the components are characterized by high heat dissipation and high conductivity and light output efficiency can get more excellent in high current operation. HPO using the key technology of manufacturing SiliLED series products (SiliLED5, SiliLED8 phosphide red light arsenide infrared light, SiliLED9 nitride blue-green, SiliLED2 nitride, ultraviolet light) is the world's few can provide a full spectrum of the vertical structure of LED professional chip manufacturing company.

Vehicle lighting LED lighting application of blue ocean market, Liansheng Optoelectronics in vehicle lighting has long layout. The company was founded at the beginning of the cooperation with domestic and international development of Dachang, Taiwan the first silicon substrate vertical structure LED applied to vehicle company, application performance has accumulated over the years, have a good reputation in the industry, in addition to the original red and yellow light on phosphide products should be in the rear direction of the light, the more active layout products in the headlights, nitride white lamp market. Recent cooperation with domestic manufacturers to develop LED headlamps, through a variety of vehicle certification and reliability specifications, such as TS16949, AEC-Q101... A map, for the use of high brightness LED products the headlights, operating under the 1A up to 1200 lumens, product performance and international manufacturers of products racing together bridle to bridle.

With the importance of driving safety and the development of intelligent vehicles, arsenic infrared (IR) products will be more widely used. The photoelectric 850/940nm double quantum well structure (DualJunctionMQWs) high power 350mA products, in the current operation, the output power is up to 370mW, is also actively promote the use of the car with the use of night vision system, SiliLED5, SiliLED9 and SiliLED8 expect the products to help customers create more high-quality products and enhance market competitiveness in the automotive market.

The same as the invisible light products, UV products for high power, high flux density requirements and stable reliability requirements more stringent. The photoelectric vertical type silicon substrate bonding patented technology LED, very suitable for the light output effect more excellent in high current operation. In the case of 80mil395nmUVLED, in the 2.5A operating under WPE 48%, can be a long time stable operation in the output power density of up to 12W/cm2, UVLED to market customized production requirements, Liansheng and system vendors to cooperate closely, and develop 5050 package UVLED module (385-405nm), used in printing ink dry curing, in the current 2.5A under the drive of up to 5000mW light output (Figure two, figure three).

The 365nmUV is in close proximity to the InGaN material limit, and the reliability of the product is more important for the quality of the epitaxial layer, the wafer fabrication process and the optimization of the electrode design. UV has worked in Liansheng optoelectronics products for many years, the new version of 46mil365nmUV with high temperature and low doped InGaN high-speed electron diffusion structure, and collocation new electrode n-AlGaN, transverse conduction electron ascension, to solve the problem of poor n-AlGaN diffusion current, and thus enhance the overall brightness, and because of the uniform current spreading to the whole grain, operating temperature also the average spread to whole grains, and thus enhance the reliability of the new version of the 365nmUVLED (Figure four). The light intensity distribution of light intensity, the new version of 365nmUVLED accounted for all 80% of the area in the area of 1500~2000a.u., and the old version of the 365nmLED light intensity accounted for about 55% of all the area in the area of 1500~2000, the other 35% distribution in 1000~1500a.u., so the uniformity of light, as well as the overall light intensity, the new design is good light intensity distribution (Figure five).

The photo on the wafer with high power vertical roots LED ten years, accumulated rich technical strength and integrity of the patent layout, also obtained the approval and support of products to customers. Looking into the future, we hope to become the ideal brand of high stability and reliability. The recent introduction of new strategic shareholders, future cooperation in equipment upgrading and product integration, believe to be able to inject new energy for the development of. The photoelectric chairman Dr. Zhang Zhisong said, in the current fierce competition in the market of optoelectronic semiconductor, photoelectric technology based on the uphold the visible light years of the products, used in new product development -- not visible, it can significantly enhance the luminous efficiency and product stability.

The current high-end products IR and UV have been recognized by customers, hope in the LED competition in the Red Sea, play the artisan spirit - focus on quality and effectiveness, create a new blue ocean products, work hard together for the development of green industry in Taiwan.

UVT high temperature eutectic UV package

In the UV customer demand for the integration of product, HPO in order to give customers better products experience, synchronous UV packaging and system module integrated products and services, in part by the UVT package (AMP) product packaging services a full range of UV, 430nm, 360~ band UV package by power by 1W~30W industry-leading ultra high power UV single crystal packaging products, a full range of collocation UVT specifically for eutectic process of ultra high power for the current carrying capacity is far more than the general nano silver colloid is more than 2 times, to provide customers with cost-effective UV package body. UVT's unique packaging services provide customers with diverse packaging options, K1, 3535, and 5050...... Et al., *UVTUV product summary:
