A new view of the blue sea market: the market for UVLED vehicles with optoelectronic and Otto

Optoelectronic all-optical silicon substrate

HPO has the earliest silicon substrate bonding technology and patent in the world. In the process of wafer fabrication, the key technology is used to replace the substrate (such as sapphire substrate, gallium arsenide base plate) used in the growth of the epitaxy into silicon substrate, using its high heat dissipation and high conductivity to improve the reliability of the element. It can get better optical output efficiency under high current operation. HPO uses this key technology to produce SiliLED product series (SiliLED5 phosphide red yellow light, SiliLED8 arsenide infrared light, SiliLED9 nitride blue and green light, SiliLED2 nitrogen ultraviolet light). It is a professional chip manufacturing company in the world to provide full spectral vertical structure LED.

Car lighting is the blue sea market for LED lighting application, and the lighting layout of Liansheng photoelectricity has long been used in vehicle lighting. At the beginning of the establishment of the company, the company developed with the domestic and international big factories. It is the first company in Taiwan to apply the silicon substrate vertical structure LED to the car. It has accumulated many years of application performance and has a good reputation in the industry. Besides the original phosphide red yellow light products should be in the brake lamp and direction lamp, and the nitride white light is more actively laid out at present. Product in car headlights, daylight market. In the near future, we cooperate with domestic big factories to develop car LED headlights, which have passed all kinds of vehicle authentication and trust standards, such as TS16949, AEC-Q101... Figure 1 is a high luminance LED headlamp using a winning product. It operates at 1200 lumens under 1A. The performance of the product is in parallel with the international factory.

With the attention of traffic safety and the development of intelligent vehicles, the application of IR (infrared light) products will be more extensive. Liansheng photoelectric 850/940nm dual quantum well structure (DualJunctionMQWs) high-power product, under the 350mA current operation, the output power can reach 370mW. At present, the use of the vehicle night vision system is also actively promoted, and the product of SiliLED5, SiliLED9 and SiliLED8 is expected to help customers to produce better products in the car market. Improve the competitiveness of the market.

As a product of invisible light, the application of UV products is more demanding for high power, high light flux density demand and stable trust. LED, a vertical silicon substrate bonding technology with optoelectronic, is very suitable for better optical output in high current operation. Taking 80mil395nmUVLED as an example, the WPE reaches 48% under the operation of 2.5A, and can be operated for a long time under the output power density of up to 12W/cm2. The UVLED market is biased toward the custom-made demand, and the win is closely matched with the system manufacturers. The 5050 package UVLED module (385-405nm) is developed together, so that the printing ink is dry and solidified in 2.5A current drive. Move, up to 5000mW light output (Figure two, figure three).

365nmUV is close to the limit of the InGaN material in the epitaxial composition. The quality of the epitaxial layer, the fabrication process of the wafer and the optimization of the electrode design are more important to the trust of the products. The UV product has been ploughed for many years. The new version of 46mil365nmUV added to the high temperature and low doped indium nitride high speed electronic diffusion structure, with the new electrode of n-AlGaN and the transverse conduction of the enhanced electron, to solve the problem of the poor diffusion of the n-AlGaN current, and to improve the overall brightness, and spread the whole current to the whole. The grain, the operating temperature also spread to the whole grain, and then the reliability of the new version of 365nmUVLED (Figure four). In the light intensity distribution, the area of the new 365nmUVLED light intensity at 1500~2000a.u. accounts for 80% of the area, while the old 365nmLED light intensity in the 1500~2000 area accounts for about 55% of the area and the other 35% is in the 1000~1500a.u.. Therefore, the new design is better for the uniformity of light and the overall light intensity. The distribution of light intensity (Figure five).

Liansheng optoelectronics has been ploughing deep ploughing in high power vertical LED chips for ten years. It has accumulated rich technical strength and complete patent layout, and also obtained customer recognition and support for products. Looking forward to the future, it is expected to become an ideal brand for high stability and trust optoelectronic components. The recent introduction of new strategic shareholders, the future cooperation in equipment upgrading and product integration, believe that the development of the success of the injection into the new energy. Dr. Zhang Zhisong, the chairman of Liansheng photoelectricity, said that in the current competitive optoelectronic semiconductor market, Liansheng optoelectronic holds the technology based on the technology of visible light products deep ploughing for many years. It can be applied to new products, the development of invisible light products, and also greatly enhance the luminous efficiency and stability of the products.

At present, the high-end products of IR and UV have been recognized by the customers. It is expected to play the spirit of the craftsman in the red sea of LED, to improve the quality and efficiency, to create the new blue sea of the product, and to strive for the development of the green energy industry in Taiwan.
