The Right Choice of Current-Limiting Resistors for Constant Voltage LED Drivers

There are different resistor types for LED lighting available (Img: Riedon Inc) While LEDs are mostly driven by current sources, there are also several applications where constant voltage drivers are used. In that case current limiting resistors are mandatory. But that raises the question which resistor is the right one to guarantee reliable and accurate control while not compromising efficiency. Phil Ebbert, VP of Engineering at Riedon Inc. explains what to take care of and how to determine the correct parameters. Read more »

LED Lighting Masters the Art of In-Flight Calm on Airbus A380s and Boeing 787s

A380 Airbus Cabin Aboard a state-of-the-art aircraft might be the last place you would think of yourself enjoying a warm “candlelit” dinner, followed by a good night’s sleep under a starry night sky. The truth is, the latest aircraft cabins seek to provide just that – a revolutionary in-flight experience through the use of mood lighting. Mood lighting uses the full spectrum of colors and the ability to change these colors continuously with LEDs to mimic or enhance a sunrise morning or a bright, fresh afternoon or a cool evening that winds down the day. These lighting effects even seek to reduce your likelihood of jetlag. LED lighting programs can be specifically designed to gradually shift your waking and sleeping biorhythms to match that of your destination city. Read more »

Why Pin Fin LED Coolers Perform Better Under Tilted Position?

For passive cooling, both, simulation and measurement results demonstrate the advanages of a pin fin design over conventional fins when tilted more than 50° For the experiment we compare the ModuLED 9980 with the LPF11180-ZHE. The ModuLED 9980 is a passive LED cooler from extruded aluminium with a diameter. of 99mm and a height of 80 millimeter, thermal resistance under vertical position 1.02°C/W. The LPF11180-ZHE is a passive LED cooler with pin fin structure with a diameter of 111mm and a height of 80mm, thermal resistance under vertical position 1.07°C/W. Read more »

Alternative Calculation Method Will Improve Thermal Analysis of LEDs - by Michiel Krüger, Ph.D. - Philips Lumileds

Figure 1: LED Definition An alternative method to estimate the amount of heat generated by LEDs will help increase the accuracy and streamline the thermal analysis of white LEDs. Up until now, thermal analysis of white LEDs has been an imperfect science. Too often LED lamp and luminaire manufacturers rely on insufficient, inaccurate or intangible data to determine the thermal performance of the LEDs in their applications, and, as a result, may over-engineer their heat sink design.

Obtaining the Highest Candle Beam Power for Spotlights

Philips Lumileds Webinar Sponsor Philips Lumileds --- Lumen density in the LED source is very significant in final design. Obtaining Center Beam Candle Power is a goal in high quality applications including retail and architectural lighting. High Power LEDs are the perfect solution to creating high lumen intensity from a very small light emitting source. Creating a very high lumen per mm square enables the highest center beam candle power in a system. Where other COB's need ~35-35mm for high lumen packages, LUXEON S5000 can achieve 8000 lumens in a Light Emitting Surface of just 17mm. Creating great spotlights has never been easier. Read more »
