| Electronics: Resonant Converter Based LED Drivers | HID lights suffer from several disadvantages and higher power LED lighting applications are beginning to replace them. Electrical isolation is often required in LED drivers to comply with safety standards. For the desired power levels above 50W, a two stage PFC front end plus resonant half bridge back end offers high efficiency, however this approach is avoided by some engineers because it is less common and the design process is a little more complicated. This article will describe the system in detail and go through the design steps. |

| Electronics: Quick and Reliable Driver Design with DC/DC Converters |
Lighting customers have very often special requirements to the Lighting power supplies, but need just low quantities.One customer need DALI and 30W at 350mA and 3 channels, the next one 6 channels and 120W with DMX and so on. With high quality DC/DC converters, flexible current and I/O pins as PWM or analogue solutions could be done within a very short time. |

| Technology: Fundamentals of Planar Remote Phosphor LEDs |
Planar remote phosphor LEDs are becoming very attractive for many lightening systems due to their uniform output light distribution and their slim appearance. With a planar configuration the remote phosphor’s benefits can be maximized. The light can be recycled at the output region, thus avoiding any back reflection to the absorbing LEDs, and the phosphor layer can be located far away from the warm LED, thus enhancing the phosphor efficiency by keeping it cold. The fundamentals for obtaining the utmost performance out of these Planar Remote Phosphor LEDs are herein reviewed. |
