L’enjeu d’efficacité des LED en courant fort : l’effet Auger

The efficiency challenge of nitride LEDs at High current : the Auger effect

High efficiency lighting will enable to tap a huge reservoir of energy, but LEDs need to reach efficiencies higher than the dominant fluorescents lamps, to have a lower cost of ownership. To achieve this, LEDs have to perform at the physical limits of electricity-to-light conversion efficiency, requiring mastering of the intrinsic electrical and optical properties of the materials. Today’s LEDs operate in the blue range with both 90%+ internal quantum efficiency (IQE) and light extraction efficiency (LEEs). However, the 90%+ performance of IQE is only obtained in the blue/violet spectral range at low carrier injection. The required operation at high current densities, a prerequisite to lower lamp costs, leads to nonlinear phenomena, which diminish the IQE, the droop. A recent measurement of hot electron generation in LEDs points to Auger non-radiative recombination as the main cause of droop. The “green gap” of IQE in the green-yellow spectral range also presents major hurdles. I will introduce some paths to solve droop and/or green gap: designing better LED structures leading to diminished carrier densities at high current injection, avoiding c-plane limitations by new substrates (semipolar and non polar GaN), using new concepts of active materials (quantum wires, QWRs, quantum dots, QDs), relying on lasers as alternatives to LEDs, switching to large Si substrates, …

Le smart lighting à l’ère de l’internet des objets : Passé, Présent, Futur

Affordable, easy to use and robust smart lighting networks like the NXP/TCP/Greenwave’s Connected Lighting system and the Philips Hue have become a reality and are available in retail since 2012. This is due to the availability of low cost, low power wireless microcontrollers, LED lamps with long lifetime, ubiquitous presence of smartphone and tablet for intuitive control and standardized networking protocols.
Today consumer experience is further enhanced with brighter tunable white and wide color gamut RGB(W) lamps, coverage of more lamp form factors and innovative apps integrating lighting in e.g. gaming and other consumer applications. Also cost is lowered continuously. Examples of this will be presented. Adoption in both professional as residential application will be accelerated by standardization of wireless network communication protocols example by industry consortia like The Connected Lighting Alliance and improvement of both ease-of-use and security with NFC authentication and commissioning.
MSO’s and utilities drive the deployment of full home automation networks and services that include smart lighting. As these are internet connected this gives rise to cyber security issues. By adopting best practices from banking and e-government applications like the use of secure elements these concerns can be addressed.

Approches sur Alimentation et circuits de contrôle pour LED

Solid-state lighting using LEDs provides increased mean-time-before-failure and higher efficacy compared to traditional fluorescent, HID and incandescent lamps. The distributed nature of lighting modules in commercial and industrial environments makes them ideally suited to act as sensor nodes, connected in a mesh network, within smart buildings. The Smart Lighting Modules can be equipped with a communication transceiver and a wide variety of sensors to locally detect temperature, power consumption, ambient light, occupancy, noise, motion, humidity and smoke. This talk will address two topics; (1) advanced driver schemes to extend LED lifetime through active thermal management and redundancy and (2) integrating the power conversion and communications functions in high-power LED modules using Visible Light Communication (VLC).

Les Luminophores éloignés pour éclairage

Solid state lighting is rapidly taking over as the preferred lighting and backlighting method, due to the high efficiency and long lifetime of LEDs. In the common approach to generate white light, a colour conversion material (or phosphor) is put directly on top of a blue-emitting LED, which puts stringent requirements on the performance of the phosphors. Although the number of phosphors is sheer endless – considering all possible combinations between dopant(s) and host compounds – only a surprisingly low number are currently used in LEDs. Therefore we highlight the spectral, temporal and thermal requirements for LED phosphors. An alternative consists of spatially separating the LED chip and the phosphor in a so-called remote phosphor design. In this presentation we focus on the advantages and challenges of this particular approach, compared to on-chip phosphors. Both traditional phosphors and quantum dots are considered.

L’impression 3D éclaire les LEDs

3D printing, also known as additive manufacturing, is a method for making three-dimensional objects from a digital model without tools or molds. Objects are made by laying down successive patterned layers of materials. Compared to injection molding, 3D printing is faster and less expensive for low volumes: cycle time is minutes instead of weeks. “Shape complexity for free” and “consumer mass personilazation” are attributes linked to 3D printing. Materials are not limited to plastics: also various kinds of metals and ceramics are available. 3D printing offers enormous flexibility to demonstrate and manufacture, e.g., holders and heat sinks for LED lighting.

After the invention of Printoptical technology by LUXeXceL, 3D is now available for the manufacturing of optics, too. Surface quality required for illumination optics, and even for imaging optics, is available without any postprocessing (polishing, painting, coloring etc.). 3D printed optics opens possibilities to ultra-fast prototyping and product development, production ramp without investments in tooling and molds, and print on demand (stock-free manufacturing). Optics can be easily and cost-effectively customized for each light source or customer demand increasing the efficiency of LED lighting solutions and decreasing light pollution.

Various kinds of nanostructures and conductive materials can also be 3D printed. This opens possibilities to embed electronics with optics or even printing LED sources or displays (inkjet-printed quantum dots).
This presentation gives the state-of-the-art of 3D printing for LED lighting and highlights its future opportunities.

Metrologie appliquée pour nouveaux SSL

Since the establishment of basic Metrology for SSL, products have significantly changed and became more complex. Therefore, there is still a demand for Metrology for novel SSL. Moreover, the focus of Metrology for SSL has shifted to: Advanced Applied Metrology for novel SSL which provides so called reference “multi-standards” and harmonized written international standards for testing.
Advanced Applied Metrology for novel SSL demands the development of a new generation of transfer standards especially made for test laboratories, not only to provide a traceable anchor point for their setups to assign SI traceable values to a measured quantity, but also to enable test laboratories to check the influence of SSL product dependent characteristics on a test result. The European Metrology Research Programme (EMRP) is providing support to the project called “ENG62 MESaIL” aiming to fill this gap.
Absence of international written standards and testing programs is one of the obstacles in the uptake of SSL products by the EU market with full user confidence. Therefore, any contribution to speed up the process of harmonization is very welcome. International Energy Agency (IEA) 4E SSL Annex is working on this subject since 2010 and is aiming to significantly reduce the obstacles in the coming 5 years.
In this talk, a roadmap for the Advanced Applied Metrology for novel SSL will be presented, with the focus on the harmonization of reference and written standards. The results of recent developments in Europe including comparisons among NMIs and test laboratories will be discussed.

Les bénéfices métriques sont la clef pour une plus grande valeur des SSL

Benefit metrics are the key to greater value from SSL

The over-arching reason for installing electric lighting is to provide benefits to users such as
safety, security, productivity, and well-being. We presently have very limited ability to engineer
those benefits because we do not have the ability to measure lighting as it supports those
benefits. For nearly a century we have implicitly assumed that meeting a recommended photopic
illuminance level supports the expected benefits. Over that same time period a great deal has
been learned about the impact of light on human neurophysiology and behaviour. These studies
from neuroscience form the realization that meeting a photopic illuminance level may or may not
support the desired benefit at the lowest cost. Therefore, until new benefit metrics are developed
and utilized the full economic potential of SSL technology will remain unrealized. Several new
benefit metrics based upon neuroscience have recently been proposed. Lighting specifications
can use these benefit metrics to better realize the economic potential from SSL for different
applications. And because benefits can now be engineered, greater value can be realized for
manufacturers and specifiers, as well as for the users of SSL.

Nouveautés sur l’industrie LED 2014 : Focus et tendances à venir

In 2013, the LED technology has really started to spread beyond general lighting, with LED penetration rate superior to 5% in some applications (such as residential lighting, commercial lighting and road and street lighting). However, to enable massive adoption of the technology, LED-products still require a cost decrease in order to be able to compete with incumbent technologies (CFL, halogen…). Additionally, the switch from a display driven market to a Solid State Lighting (SSL) driven market poses a lot of challenges for the many LED manufacturers that are not vertically integrated all the way through lamps / luminaires.
In 2014, after years of anticipation, promises and excitement, General Lighting is no more “at the corner” for the LED industry. However, to successfully convert this opportunity into bottom cash lines, the industry will have to undergo some major transformations, and many challenges await. First of all, the highly fragmented LED industry with more than hundreds of chip makers and thousands of packaging companies needs some serious consolidations. Secondly, the paradigm changes of SSL implied that it’s not anymore simply about making bulbs and sticking them into luminaires: to reap the full benefits of LEDs, products will have to be designed out of the box, almost from the chip to the final installation in our living room or city hall.
Developments toward technical innovation and manufacturing excellence both also appear as mandatory conditions to continue to decrease the “$/lm” of LED device. However manufacturers should not focus only on reducing packaged LED costs, but they should also decrease other component costs (IC driver/power supply, optics…) as light source cost reduction will reach its limit. Beside organization and rationalization, the industry must also educate all the stakeholders. This mean not only consumers but also architects, developers, light designers, contractors (…).
In this presentation, we will present an overview of the LED market and industry, detailing: market metrics, key players, recent trends, technology under development, concrete examples (…).

LED Drivers and Controls

Compared to the voltage converters as a voltage source, LED drivers function as a current source to provide LEDs a regulated current for the desired ligting. Based on the equivalent circuit model of LEDs, the constant-current and constant-voltage drive strategies for different LED lighting applications are illustrated. Considering the LED light characteristics, the linear and burst-mode dimming controls are introduced. The features of the single-loop and dual-loop control mechanisms used for LED driver systems are detailed. For the time-domain and frequency-domain circuit simulations, a convenient mathematical model uses only three V-I points: knee point, rated point, and maximum point on the LED V-I curve, which can be directly obtained from the LED datasheets, to generate the look-up table of the piecewise linear behavior model instead of the conventional complicated and time-consuming equivalent circuit model.

L’éclairage LED aux yeux des citoyens : l’approche utilisateur originale de l’éclairage extérieur de la ville de Jyväskylä’

Jyväskylä, the seventh biggest city in Finland is a lively and attractive place to live and the northernmost City of Light in the world. Jyväskylä is the winner of the international city.people.light competition from year 2009. The jury specially pointed out, that the lighting in the city is done for the inhabitants, not for the bright image of the city. Jyväskylä nowadays promotes over 80 illuminations, done by the city and by private property owners. In Jyväskylä lighting is an essential part of urban planning.
The speech is about outdoor lighting from the users’ point of view. Temporary LED park in Lutakko housing area has displayed several different types of led pole luminaires and it has been introduced widely to the residents but also to designers and property managers. The aim of the project was to show good and less good examples and to make decision making easier. Choosing led luminaires nowadays is a real challenge, even to lighting professionals. LED park has been very practical tool in helping different apartment building actors to find a solution to replace mercury lighting in their yards.
Other case introduced is a brand new housing area called Äijälänranta which is the first area fully illuminated with led lights. With luminaire-based programming the crossings and pathways are always brighter than the street areas. There are three different lighting schemes; normal lighting (lighting class ME4b), active hours (ME4a) and night time lighting (ME6). The city will collect information from the users after the system has been fully in action for one year (last quarter of 2015). The information will be used in future lighting design projects.

The business model of the lighting industry is changing. Light as a Service is almost guaranteed and it will result in a merger between the lighting and communications industries. Lighting companies now have the opportunity to become infrastructure providers, offering communication services as part of an integrated value proposition. Li-Fi, the high-speed, bidirectional and networked delivery of mobile communications through visible light creates a unique opportunity for this inevitable merger. Li-Fi enabled lighting infrastructure can become the backbone in facilitating the Internet of Things, able to satisfy the exponential growth in wireless data demand. It can provide a step-change in the available capacity of wireless communications. Li-Fi is not a protocol for lighting control. It is a disruptive technology that will complement existing communications and revolutionize value propositions within the lighting industry.

he high-brightness, packaged LED market is forecasted to reach US$15 billion by 2016. However, significant cost-reduction breakthroughs are needed to allow continued market growth. Up to now, the driving forces were first an increase of the performances in terms of lm/W (which is now clamped close to the maximum theoretical value) and secondly an increase of the substrate sizes in order to decrease the lumen cost. But conventional LEDs (either on sapphire or on silicon) suffer from large lattice and thermal coefficient mismatches between the active area and the substrates that prevents LED industry to continue to benefit from cost reduction thanks to the scaling effect.

Wide-bandgap gallium nitride nanowires are considered to be able to change the paradigm and are foreseen as attractive building blocks for high efficiency and low cost solid-state lighting applications. In this paper, we will present an overview of this innovative technology.

Amener de l’efficacité énergétique dans les bâtiments à un nouveau stade grâce à l’éclairage intelligent

Energy saving made easy thanks to smart lighting control
Worldwide approximately one fifth of the electrical current is used for lighting. In 2000 the European Climate Change Programme (ECCP) calculated a saving potential of 24 million tones CO2 per year for lighting in the non-residential area (15 % of the total consumption at that time). Recent calculations even assume a cost saving potential of 4.3 billion Euros in the EU. This equals in kilowatt hours the emission of twelve medium-sized power plants or more than 50 million barrels of oil or 28 million tones CO2 per year. With this the ECCP estimation would be exceeded significantly.
Only few consumers calculate the total cost of ownership of a lighting installation, meaning not only the investment but also the power consumption and the lifetime of the lamps. That is why still systems are installed, which seem to be low-priced at first sight, but in the end result in being energy inefficient, cost driver and, therefore, as environmental burden.
For OSRAM sustainable environmental protection is part of the daily business. Innovative products are the prerequisite for energy efficient lighting solutions which do not only ensure low electricity costs but also contribute to a reduction of carbon dioxide emissions. Replacing conventional products with new, energy efficient solutions protects the environment and even reduces (operating) costs.
In this presentation we will show examples of intelligent lighting controls and how they can contribute to a sustainable development and offer new opportunities.

Ajouter de l’intelligence aux drivers LED

Il n’y a pas si longtemps que cela, on avait besoin d’ampoules électriques pour s’éclairer et on pouvait à la rigueur varier l’intensité afin de créer une ambiance originale, mais cela s’arrêtait là. Le lancement des LED sur le marché bouleverse les fondements du secteur de l’éclairage. Actuellement, l’apparition de réseaux d’éclairage intelligents est une fois de plus sur le point de révolutionner notre conception de l’éclairage. Les alimentations électriques LED commencent à intégrer plusieurs technologies différentes telles que ZigBee, DMX, KNX et même DALI, ce qui permet d’améliorer les conditions d’éclairage, mais aussi de collecter des informations et d’augmenter l’efficacité d’un système. Dans cette présentation, nous nous intéresserons tout d’abord au fonctionnement des drivers dans ces configurations de communication et nous verrons ensuite pourquoi il est parfois difficile de communiquer par le biais de différents protocoles. En règle générale, les alimentations électriques LED sont conçues pour un seul protocole de communication spécifique. Néanmoins, RECOM propose aujourd’hui un driver intelligent à la pointe de la technologie qui intègre sans problème un grand nombre de ces technologies dans une unité très polyvalent.

Nouveau design d’optique pour LED permis par le silicone

Today’s LED lamps and luminaires evolved from the materials available at the time of their design. From this, one may accurately intuit that advances in materials technology always translate into more sophisticated LED designs. However, with the recent emergence of moldable optical silicones, the advances in higher-performing LED concepts have progressed exponentially, rather than linearly, and promise to usher in a new generation of deeply competitive and highly reliable solid-state light sources for architecture, outdoor illumination and other high-brightness general lighting applications.
Moldable optical silicones are much more than an easily moldable substitute for glass, or a more photo-thermally stable alternative to plastics. Driven by increasing market demand, these materials are actually redefining the boundaries for LED module, lamp and luminaire design from the ground up. The breakthrough potential of this highly advanced technology, however, brings the challenge of learning how to re-approach traditional optical design using a novel materials chemistry with unique properties and greatly expanded capabilities.
This presentation will detail the design of several inspired, yet real-world LED lighting applications made possible only through the use of high-performance moldable optical silicone technology. Pending customer approval, examples may range from multifunctional or high-precision lenses, substantially larger optical parts and transparent or reflective components able to deliver more reliably consistent performance after long exposure to extreme lumen densities or temperatures of 150 C. In addition, the presentation will demonstrate the innovative ways that silicones are solving challenges in the assembly and manufacturing of LED Lighting components and parts.

Vers une Stratégie Européenne de l’Eclairage

A European Strategy for Lighting is required since the lighting industry is undergoing the biggest transformation since the times of Thomas Edison. This is driven by rapid technology innovation (esp. in Solid State Lighting) and European energy efficiency regulation

The transformation provides challenges and opportunities for European users and lighting industry (see 2011 Green Paper « Lighting the Future »). A coherent European strategy for policy coordination and innovation is crucial to support development and wider uptake of energy efficient lighting products, foster the competitiveness of European industry, secure employment, and ensure Europe’s role as key technology leader. The talk will elaborate on this strategy which also links to the results of the just completing CIP funded lighting city demonstration projects LED4ART and ILLUMINATE (http://www.cip4led.eu/) as well the coverage of proposals of the first calls of Horizon 2020 plus the opportunities for 2015 and beyond

Les secrets pour l’utilisation des polymers pour le remplacerment du métal et la gestion des applications thermiques

New options for creating innovative lighting systems are available for designers and manufacturers. For example, thermally conductive engineered polymers can now be used to replace aluminum as an efficient heat exchanger in LED lighting designs. These thermally conductive polymers can be engineered into final lighting designs with the support of computer-aided heat dissipation and modeling simulation.
Replacing metal with injection moldable polymers opens up a new level of design freedom, giving lighting designers and manufacturers the ability to create differentiated styles and concepts that fulfill their goals for performance and design. Polymers also reduce weight and create manufacturing efficiencies that help lower overall system cost. Cost savings are also possible through material savings, scrap reduction, secondary operation elimination, cycle time reduction and part consolidation. The chemical resistance of these materials makes them feasible for use in a variety of residential, commercial and industrial lighting applications. By switching from metals to polymers, designers can minimize environmental, health and safety risks, and improve material recyclability, while still realizing needed dielectric properties and flame resistance.
This paper details why thermally conductive engineered polymers should be considered for lamps and luminaires “heat sink” components, explains how technical challenges are overcome, and describes the thermal mechanical performance that can be achieved. Real-world examples of currently commercial lighting applications will help illustrate the options available to designers and manufacturers.
