A LED–LED-based photoplethysmography sensor
Physiological Measurement, 2007A high sensitivity, low power and low cost sensor has been developed for photoplethysmography (PPG) measurement. It uses standard light emitting diodes (LEDs) as both light emitter and detector, pulse-based signal conversion techniques instead of the classical analogue-to-digital convertors (ADCs) and a general purpose microcontroller for the ...

LED-Temperatursensor (LED Temperature Sensor)
tm - Technisches Messen, 2007Eine einfache Methode der Temperaturmessung mithilfe einer Lumineszenzkonversions-LED wird vorgestellt. Das Verfahren wurde an einer Standard-Weißlicht-LED erprobt und weist eine Genauigkeit von ca. 2 °C auf. Es wird gezeigt, dass bei Verwendung anderer Lumineszenzstoffe die Genauigkeit signifikant erhöht werden kann.

LEDs and Use of White LED for Lighting
2014LED is an acronym for “light emitting diode.” The first important fact is that LED is an electronic component, a diode, a component that can conduct current in one direction and not the other. As many other electronics components, controlling a LED is an easy topic, in order to obtain different behavior. Due to the fact that a LED must produce light, a

Organic LEDs Combined With Inorganic LEDs
Journal of Lightwave Technology, 2011An organic light-emitting device (OLED) is coupled with inorganic LEDs to strengthen the OLED's weak point (i.e., low luminous intensity). To this end, side-view LED bars are deployed on the sides of the glass substrate of OLED. To extract not only OLED light but also LED light from the glass substrate, a microlens array (MLA) film is attached to the ...
