he core technology of LED lighting is LED lamp beads and LED power supply. The core technology of LED power supply is the specialized integrated circuit chip. The past decade has seen great advancement of LED lighting power drive chip technology, from the universal power drive chips in the beginning to the constant current chip developed specifically for LED lighting. With various series, specifications and variety, the chip is applicable to different settings and light sources. As LED light source lamp bead technology rapidly develops from LVLED to HVLEDs, the constant-current drive chip for LED primarily based on switching constant current and high voltage linear constant current is used massively. High-voltage linear constant current drive develops in two directions, i.e. constant power and linear constant current control plus external MOS. The power drive chip must intensively integrate many functions, and power drive application circuit must be simplified in order to meet the requirement of massive LED light sources and light fixture market. The design of the power drive chip must satisfy the practical needs of LED light sources and luminaire products. The must-have functions should be kept but the redundant functions must be removed. Reducing the die area can increase the number of power drive chip on a wafer unit and lower its cost and price. China must develop proprietary technology of power drive integrated circuit chips with its own IP right. China is fully capable of designing, taping, packaging and testing power drive integrated circuit chip, which enables us to provide reliable and continuous delivery at a stable price to the application side. The optoelectronic design of LED lighting products is an inevitable trend. The optoelectronic engine technology with HVLEDs and linear drive chips designed on the same module is already mature, massively produced and widely used in LED lighting manufacturing industry, resulting in the rapid development of linear power drive chips. We have also seen new products design in various categories of LED lighting power drive integrated circuit chip in response to the growing needs of emerging markets. These applications include non-isolated low PF, non-isolated high PF, isolated low PF linear constant current for general lighting, switching power supply SCR dimming and linear power supply SCR dimming, PWM dimming constant current drive chip for smart lighting, low power constant voltage power supply chip, level conversion chip, isolated high PF for high power luminaire equipment, strobe chip, switching dimming and color chip and many more. Power drive integrated circuit chip has evolved in the context of "thinking lighting and transformation" in response to diversified demands for LED lighting. As new generations of power chips are developed, we are striving for winning in the blue ocean of LED lighting industry.
Alec Yan is a senior engineer, part-time professor, technical advisor, independent director of the board and volunteer in lighting industry. He had worked as an electronic engineer and marketing manager in Chinese and foreign companies for over 50 years. After retirement, he has worked as a part-time professor at Shanghai Institute of Microelectronics of Peking University for eight years. In the past decade, based on the in-depth analysis of and insights into LED lighting market, he has made a number of technological innovations, such as "switch constant current power drive chip", "high voltage linear constant current drive chip" and related application technologies，a full set of design, production technology and automated production equipment of "optoelectronic engine" and "LED filament lamp". He has actively advocated and promoted the wide application of technologies related to design, application, and production. After years of development, these products have now become the mainstream of the LED lighting market, supporting the robust growth of start-ups and SMEs in LED industry. LED lighting industry is moving towards integrated, simple and automated production. The key to success is innovation in technology and creativity in product design!
The efficacy of LEDs has improved 10-fold and seen equivalent price erosion over the past decade. The increased efficacy has led to reduced power dissipation and hence reduced need for cooling. All leading to smaller luminaires with a higher design freedom and reduced cost. The LED drivers have however not seen the same great improvements and have hence become the Achilles heel of most LED lighting products. New innovations are needed for the LED driver to catch up and to meet the market requirements. The volume and cost of drivers are mainly governed by passive energy storing elements (inductors and capacitors). They scale with the switching frequency and a dramatic increase in switching frequency will hence lead to highly increased power density and reduced cost. For hard-switched drivers this will however result in severe switching losses, which will ruin the efficiency and cause system failure. By combining circuits from the RF industry with the design methodology of power electronics, new driver topologies have been designed, which ideally eliminates these switching losses. This enables increased switching frequencies and hence a huge increase in power density and comparable cost reduction. The reduced need for passive energy storing elements enables removal of heavy and bulky magnetics components and temperature sensitive electrolytic capacitors. Hence enables longer lifetime on the overall luminaire and deeper integration of LEDs, LED drivers, heatsink and luminaire. The first commercial LED drivers with this technology have just launched.

Due to the increasing demands for indoor location-based services, wireless indoor positioning system has attracted much research and development attention in recent years, and the market size for indoor positioning has been assessed to be tens of billions of dollars. Compared with other indoor positioning technologies such as radio frequency, infrared and ultra-sound, visible light positioning technology has the advantages of simpler infrastructure, more efficient energy use, and higher positioning accuracy. In this talk, we will first provide an overview of indoor positioning using visible light and its state of the art. While positioning with visible light communication (VLC) infrastructure can achieve centimeter-level accuracy, most existing VLC-positioning system prototypes have some practical limitations. To overcome these limitations, we propose a new VLC positioning technique called angle difference of arrival (ADOA), which allows for arbitrary tilting and pitching of the receivers. We demonstrate both numerically and experimentally that the proposed VLC positioning system based on ADOA can achieve accuracy of less than 1 centimeter. The proposed VLC positioning technology, which has both low cost and low complexity, can be used in a wide variety of indoor positioning applications. Finally, we will discuss about the business opportunities and challenges for indoor visible light positioning technologies.

Visible light communication (VLC) is a technology that uses LEDs as data transmitters to carry information. Modulating inexpensive LEDs with data allows for the simultaneous use of lighting panels for wireless access and illumination. This dual-use approach can offer energy-efficient connectivity as well as high throughput due to the huge unregulated optical spectrum. Since light is easily contained, VLC systems are secure and can exploit spatial resource reuse to effectively form dense data networks. Future applications range from mobile Wi-Fi alternatives (popularly called Li-Fi) for large indoor spaces to vehicular communication networks. These systems are ideal for environments where RF systems are ineffective or prohibited because of the risk of electromagnetic interference or contamination. In this talk, we explore the potential of this new technology within the context of its practical limitations and present some visions on the commercialization path for VLC.

LED brings disruptive change to the industry. Over time, industry growth will be driven in three ways: - Energy saving (happening now, RoI-/Payback-driven) - Controllable light (starting to happen, adaptability and quality of light) - Connected light (early stage now, value beyond lighting) In the third stage, it will be about delivering value beyond lighting itself. Lighting fixtures will become an infrastructure backbone for anything 'SMART': Smart City, Smart Building, Smart Home. Four reasons for this: - Lights are everywhere - Lights have a fixed location - Lights are always powered - Lights will become data hubs. This will allow for functionalities well beyond lighting a space; specifically, Lights will allow data collection and diessemination. Examples include building management through heatmapping, indoor localization, asset tracking, traffic management, VLC/LiFi and many more. It will be key for the industry to understand the true value of such services in order to develop the right offer to the market and establish the right pricing strategies for such offers. I will share some real eaxmples.

We developed the world’s first Ultraviolet LED in 2000, and UV-LED is expected as not only a substitution market of mercury lamps but also a next generation light source and display panel in the near future. The UV mosquito catcher is now in common use. Recently we released reasonable price 275nm deep UV-LEDs in the market. We applied them for air purifier, sterilizer, etc.. These UV-LED applied functional products are called LEDPURE®. Furthermore UV excited micro LED panel can be a candidate of next generation display.
AlGaN deep ultraviolet light-emitting diodes (DUV-LEDs) are attracting a great deal of attention, since they have the potential to be used in a wide variety of applications, such as for sterilization, water purification, UV curing, and in the medical and biochemistry fields. As a result of recent developments in AlGaN DUV LEDs, high internal quantum efficiencies (IQE) of more than 60-80% have been achieved by reducing the threading dislocation density (TDD) of the AlN, and/or by the introduction of AlN single crystal wafers. However, the wall-plug efficiency (WPE) of AlGaN DUV-LEDs still remains below 2%. The target for the efficiency of AlGaN DUV-LEDs is to go beyond an efficiency of 20%, which would make them comparable to low-pressure mercury lamps. A significant problem is that the light-extraction efficiency (LEE) is still quite low because of heavy UV absorption through the p-GaN contact-layer. Usual LEE is still below 10%. Recently we succeeded in reducing an applying voltage and obtained the record WPE of 10.8% from the DUV LED with lens. We also demonstrated the increase of LEE by introducing highly-reflective photonic crystal fabricated on both of the p-AlGaN transparent contact layer and the p-GaN contact layer. Since highly-reflective photonic crystal on the p-contact layer is enable to reduce the heavy UV absorption and keep low applying voltage, WPE will be improved to be compared with typical deep-UV LEDs.
I am currently belong to Hirayama Quantum Optodevice Lab at RIKEN and contribute to improve the light extraction efficiency of deep-UV LEDs by introducing highly-reflective photonic crystal. The current subject is computer simulation to use both of ray-tracing and finite difference time domain method for photonic crystal and bonding semi-spherical lens. Published paper is "High external quantum efficiency(10%) AlGaN-based deep-ultraviolet light-emitting diodes achieved by using highly reflective photonic crystal on p-AlGaN contact layer", Applied Physics Express 11,012101(2019).
Expected to replace traditional ultraviolet mercury lamp light source, ultraviolet light-emitting diodes (UV-LED) based on AlGaN are widely used in such fields as solid-state lighting, purification and disinfection of water and air, as well as medical treatment and curing of skin and blood. However, as the emission wavelength becomes shorter, ie, the aluminum composition increases, the preparation of high-quality AlGaN materials becomes increasingly difficult. This is partly due to the large lattice mismatch between the AlGaN film and the substrate of the high aluminum composition, which increases the density of various defects on the film. It is also caused by the increase in the aluminum composition and the growing difficulty of AlGaN doping and activation, which leads to poorer ohmic contact and higher operating voltage. As a result, there is a huge gap between AlGaN-based UV-LEDs and GaN-based blue LEDs in terms of both internal quantum efficiency and luminous power (brightness). The valence band structure of AlGaN-based Ni-nitride materials favors the optical field direction parallel to the C direction, or the optical transition perpendicular to the M (10-10) surface and A (11-20) surface, both of which are non-polar surface unaffected by the quantum confinement Stark effect. Therefore, non-polar AlGaN-based materials naturally become the ideal material for UV-LEDs. However, compared with AlGaN-based materials grown on polar C-surface, those grown on non-polar M-surface or A-surface are still high in defect density. Therefore, if we can develop high-quality growth techniques for non-polar AlGaN-based epitaxial materials of M-surface or with A-surface orientation that is suitable to device fabrication and find methods to suppress defect generation, chances are we will eventually develop non-polar AlGaN-based UV-LEDs with high luminous efficiency to replace mercury lamps in water and air purification. This will have a great and far-reaching significance for environmental protection and people’s wellbeing. This presentation will start with an introduction of UV-LED research home and abroad. The speaker tries to offer a new solution to deep ultraviolet LED technology research in response to the issues mentioned above. Hopefully this new solution will pave the way for the mass application of AlGaN-based UV-LEDs in water and air purification.

Recently, necessity of new technology LED has been increased due to rising of environmental consciousness. It is UVC-LED which has wavelength range of around 260nm to 290nm. Still conventional mercury lamp is exception of the Minamata convention on mercury, with recent technology development and evolution of practical technology , UVC-LED are approaching to be substitution technology.
