Advanced Lighting Design Enhancing Connection between People and City 

Abstract
LED that has been developed in these 5 years has changed the common sense of urban lighting design. Tokyo Skytree, its height is 634m, opened in 2012 in Tokyo is totally illuminated by customized LED which had been developed from 2008. Lighting design of this new landmark of Tokyo was designed under concept of “Iki and Miyabi “, which expresses the sense of Tokyo shared from EDO (old Tokyo) era. Gentle brilliance and beautiful color at night have been well appreciated by everyone and made many people have strong interest of lighting design.

ICC light and music show in Hong Kong was started from 2012. This kind of lighting appears upon the surface of building is usually expressed as “Media Facade” seen in many cities nowadays. However this show is quite different from others by its lovely movies that express the feeling of Hong Kong. Thus this lighting show has attracted Hong Kong people and become new symbol at night.

Through the experience of these important projects for each city, the lighting designer will show his opinion how to make proper urban lighting and how to treat LED and other new technology of light for future.

Topic
Emerging Quantum Dot Technologies for Optoelectronic and Solid State Lighting Applications  

Abstract
Novel technology solutions will be required in order to achieve the full efficiency potential (e.g. <70% WPE) of solid state emitters for lighting applications. One such idea, which is starting to gain momentum, is the use of InGaN laser diodes for Solid State Lighting (SSL) where simulated emission can be used to overcome efficiency droop caused by Auger recombination. A second technology which has not yet reached its full potential is the use of InGaN quantum dots (QDs) to enable high efficiency optoelectronic devices. We have recently developed a novel technique called quantum size control where photoelectrochemical etching is used to fabricate InGaN QDs starting from InGaN quantum wells. This technique holds the promise of very uniform distributions of QDs as well as accurate placement of QDs in photonic structures. These two ideas can potentially be merged to demonstrate InGaN QD lasers with performance that goes well beyond that available today. This presentation will discuss the recent work at Sandia National Labs towards this vision. One day, high efficiency QD light emitters may be used, not only for SSL, but also as single photon sources, emitters for quantum information processing, and in future smart lighting systems.

LED on Silicon – Technologies and Applications

Abstract
Nitride-based visible light emitting diodes (LEDs) with high external efficiency are widely used for a variety of applications including display backlights and general lighting. Many believe that volume production of GaN-based LEDs on large diameter silicon substrates is the key to realize competitive cost of solid state lighting, similar to the evolution of integrated circuits. Alternative solutions of integration using other well-developed technologies such as flip-chip are interesting and practical. LEDoS projection technology will be presented as an example.

LED micro-displays offer diverse applications with their superior characteristics and unique performance, particularly in high light utilization efficiency (LUE), design simplicity (Backlight Unit (BLU)-free), long lifetime, and excellent visibility under bright day-light. Several LED based displays have been developed in recent years using both passive matrix (PM) and active matrix (AM) programming methods that can also be used as a novel source for projection display.

Visible Light Communication Using Solid State Lighting

  
Abstract
Visible light communication is a new way of wireless communication using visible light. Typical transmitters used for visible light communication are visible light LEDs such as LED lights, LED traffic lights, street LED lights, car headlights etc., and typical receivers are photodiodes and image sensors. New applications which will be made possible by visible light communication technology will be presented. By using visible light communication, a transmitter is capable of controlling the direction of an emitted light, and a receiver is capable of not only receiving transmitted data contents but also detecting the accurate direction of the incoming light. These capabilities enable various new applications which conventional radio-wave-based systems cannot do. Examples of such new applications are accurate navigation, robot control, advertisement, augmented reality, etc. To make new applications and services available widely in the world, establishment of standards is important as well as a new technology. Standards activities of visible light communication will be also introduced.

Development of OLED Lighting Device and Challenge in Future   

Abstract
OLED Lighting Device has a potential to change conventional lighting design and lighting itself because its light property, lightness, slimness and low device temperature when lit.

OLED Lighting Device of our company has a good point property of long life, low shift in color while usage, less tendency of light out, because we utilize our own evaporation process and film encapsulation structure. As our evaporation apparatus utilize area-evaporation source and our original process, we get above features, and it can reduce usage of source material, and reduce valuation of specification deviation of luminance and chromaticity, and then we obtain good production yield. Our film encapsulation structure reduces material cost of encapsulation, and obtains good thermal condition, good strength to external force, therefore our OLED panel suit construction.

Currently we develop applications to the market, and we execute R&D for further cost reduction and better performance, in order to expand use and production of OLED Lighting Device.

High Efficiency Organic Light-Emitting Diodes with Fluorescent Emitters

Abstract
Fluorescence-based organic light-emitting diodes (OLEDs) have continued to attract interest because of their long operational lifetimes, high color purity of electroluminescence (EL), and potential to be manufactured at low-cost in next generation full-color display and lighting applications. In fluorescent molecules, however, the exciton production efficiency is limited to 25% due to the deactivation of triplet excitons. Here, we demonstrate a novel pathway for high-efficient fluorescence-based OLEDs by applying the general concept of thermally activated delayed fluorescence (TADF) to a assistant dopant, resulted in the fluorescence-OLEDs showed high external EL quantum efficiencies of 13.4 - 18.0% for blue, green, yellow, and red emission, indicating that the exciton production efficiency reached nearly 100%.

Status and Opportunities for Phosphorescent OLED Lighting 

Abstract
Lighting is undergoing a fundamental transition from bulky legacy sources to new forms of highly efficient solid-state lighting. LEDs have now captured significant market share and OLED lighting is at a pivot point, with early entry products beginning to enter the mass market. OLED lighting performance has improved rapidly over the last two years, and based on phosphorescence, OLED lighting system efficiencies are comparable with LED systems. OLEDs offer a truly unique lighting experience based on their large area, thin form factors and excellent light quality. While costs are still high because of low production volumes, early entry products are proving very popular. The advent of flexible OLED lighting will lead to exciting new products, greatly increasing design freedom. In this talk I will review the status and opportunities for phosphorescent OLED lighting.

Advanced Material Technologies for Highly Efficient OLED              

Abstract
OLED lighting is regarded as next-generation lighting because of its thin, light and flexible features. Recently, we have constructed world's first mass production plant of flexible OLED lighting panels on plastic substrate. On the other hand, we are also developing advanced material technologies for highly efficient OLED. In 2014, we achieved world record efficiency of white OLED lighting, 139 lm / W, with good CRI (81) and CCT (2857 K), LT50 (55 kh at 1000 nits) with our light blue phosphorescent material. Such high efficiency is comparable with LED package, however, further improvement of lifetime is required for general lighting.

In this presentation, we will introduce our advanced material technologies to achieve higher performance including blue phosphorescent emitter, host and ET materials. In addition, we will report our advanced analysis technologies supporting our material development.

Socket Applications on OLED Lighting

Abstract
OLEDs require new connecting technology. OLED modules are sensitive and even fragile. A connector manufacturer has to find answers to the question how to implement a mechanical fixation and electrical connection between OLED-modules and luminaires and furthermore how to manage the exchangeability of OLEDs in an application. 'Ease of use' is one of the most important tasks.

The challenge here is to apply an electrical contact to the delicate substrate layer without destroying it. On the basis of the activities in past consortial and cooperative projects, BJB has developed several concepts. Attention has to be paid to one special challenge: linking the existing manufacturing ability of luminaire manufacturers with the new possibilities offered by LED lighting technology. Doing so, a manufacturer of connecting elements have to focus on two essential fields:

The efficient processing of LED-components in luminaires and the development and combination of separated components to create an easily manageable entity.

Electro-Optical Characteristics Test Equipment for OLED Lighting Panels   
Abstract
To meet the testing requirement of OLED lighting panels listed on the datasheet, a test equipment capable of searching panel driving current under constant luminance (for example 1000cd/m2) has been developed. With luminance and flux measurement, all uniformity, homogeneity, color property will be obtained from constant luminance measurement.

Different measurement and calculation method are investigated. OLED lighting panels fabricated by ITRI OLED lighting baseline has power efficiency 40 lm/W, CCT about 4,000 K, CRI>85. Electro-optical characteristics of OLED lighting panels are measured from luminance camera system and sphere with spectrum meter system. Due to non-lambertian situation, luminance and flux measurement are separated and characteristics of whole panel luminance, homogeneity, CCT, CRI and lm/W can be measured efficiently.

A comparison of homogeneity and non-uniformity from test results of 8cmX8cm light emitting area hybrid tandem white OLED lighting panels is investigated. Reference from CIE TC2-68, H(e=0.5) is about 0.65~0.70 when luminance non-uniformity is 15% and these panels can be classified as homogeneous. Non-uniformity should at least lower than 8% to be classified as very homogeneous H(e=0.5) > 0.8.

Test Methods for Sapphire Wafers: Geometry & Surface Morphology

Abstract
Specifications for sapphire wafers to be used as substrates for HB-LED were recently standardized in SEMI HB1 in order to serve a rapidly growing market. Verifying the requirements specified in this specification requires customers’ and suppliers’ agreement on measurement methods to be used of which so far only a few are standardized in the HB-LED and sapphire wafer industry. Standardized test methods are missing even for the basic geometrical characteristics of sapphire wafers or substrates. Therefore, standardized test methods for these characteristics would be of great benefit for the involved industries for establishing a common understanding of measurements equipment capabilities, limits and performance and for avoiding unnecessary and time consuming discussions on quality or specification issues.
 
The presentation will inform on the status of three new test methods for sapphire wafer thickness, shape, waviness and saw marks that are currently under development at SEMI Standards. These test methods will describe in detail the measurement procedure and define terms and metrics to be used for communicating the wafer characteristics. Information about the expected precision of the test methods will also be included.
