Switch Lighting: Dump your fluorescents and incandescents for this amazing new LED bulb. - By Farhad Manjoo. When I drove to the offices of a start-up called Switch Lighting last week, I wasn't expecting much.
A company representative had promised to show me something amazing—an alternative light bulb that uses a fraction of the energy of a traditional incandescent bulb and lasts 20 times as long, but that plugs into a standard socket and produces the same warm, yellowish, comforting glow that we're all used to seeing when we flip the switch. Farhad Manjoo is a technology columnist for the Wall Street Journal and the author of True Enough. Follow I'd heard that pitch before. Energy-efficient bulbs that shine like incandescents are the holy grail of the lighting industry. Switch Lighting claims to have solved all of those problems. Turned off, a Switch bulb looks like an incandescent from the future. That seems increasingly likely.

When grown at scale, most LED epitaxial wafers use sapphire or silicon carbide substrates as the starting material.
But large diameter sapphire and silicon carbide substrates are costly, difficult to process, and not widely available. As a result, production costs have inhibited the widespread adoption of LED lighting in homes and commercial buildings. But growing GaN on larger, low-cost silicon wafers that are compatible with modern semiconductor manufacturing can deliver a 75% improvement in cost over current approaches. The 135 Lumen per Watt performance was achieved at a CCT of 4730K using a single 1.5mm power LED operated at 350mA. These LEDs have extremely low operating voltages, requiring just 2.90V at 350mA and <3.25V at 1 Amp. The move to a Silicon substrate will be a revolutionary step for the LED industry, and Bridgelux is well- positioned to take full advantage of the introduction of this technology.

Prototype OLED lighting panel developed by Lumiotec Demonstration of a flexible OLED device There are two main families of OLED: those based on small molecules and those employing polymers.
Adding mobile ions to an OLED creates a light-emitting electrochemical cell or LEC, which has a slightly different mode of operation. OLED displays can use either passive-matrix (PMOLED) or active-matrix addressing schemes. Active-matrix OLEDs (AMOLED) require a thin-film transistor backplane to switch each individual pixel on or off, but allow for higher resolution and larger display sizes. An OLED display works without a backlight. History[edit] The first observations of electroluminescence in organic materials were in the early 1950s by André Bernanose and co-workers at the Nancy-Université, France. The first diode device was reported at Eastman Kodak by Ching W. Working principle[edit] Schematic of a bilayer OLED: 1. Indium tin oxide (ITO) is commonly used as the anode material.
