TOPIC: The Role of Power Electronics
in Lighting Applications
Abstract: Currently, power electronics is a mature technology that allows for the effective use of the electric energy in all kinds of applications. Power electronics makes it possible to efficiently transfer electric power from an input source to a load both with different characteristics of amplitude and frequency. In the lighting world power electronics have served since the very first electric lamp was developed at the end of the 19th century. At the beginning, power electronics allowed us to efficiently adjust the incandescent lamp power to provide the required lighting level for each task. Later, power electronics techniques were used to efficiently supply discharge lamps, such as fluorescent and high intensity discharge lamps. More recently, power electronics converters are being used to drive LED lamps, allowing for a great variety of functionalities, from dimming to color adjustment and even transmission of data through the emitted light. In this keynote we will make a review of the power electronics applications in lighting during the last century and of the new trends that are expected in this field.

TOPIC: The Amazing History of LED Lighting
Abstract: Humanity became emancipated the day it became independent of sunlight. We were thus able to have time to develop writing, art, science and technology, to improve our comfort and our life expectancy. The invention of artificial lighting is a pillar of humanity development.
After fire, oil lamps, gas lamp, discharge and incandescent lamps... the arrival of LED lighting is the last revolution on a global scale. But what do you know about LEDs? What is its impact on the world? When was it discovered? By who? This short presentation will enlighten you on an object that has become familiar and common in just a few years.
