Light Emitting Diode or the LED Tutorial

They are the most visible type of diode, that emit a fairly narrow bandwidth of either visible light at different coloured wavelengths, invisible infra-red light for remote controls or laser type light when a forward current is passed through them. A “Light Emitting Diode” or LED as it is more commonly called, is basically just a specialised type of PN junction diode, made from a very thin layer of fairly heavily doped semiconductor material. When the diode is forward biased, electrons from the semiconductors conduction band recombine with holes from the valence band releasing sufficient energy to produce photons which emit a monochromatic (single colour) of light. Because of this thin layer a reasonable number of these photons can leave the junction and radiate away producing a coloured light output. LED Construction LED Series Resistance.

The Design Brief In Home Displays Ltd approached Shore to carry out the concept design, development and supply of their new In Home Display product, to be launched as part of the Smart Meter Implementation Programme.

Shore Design - In Home Displays

This is one of the first of a new breed of display products which are fully compatible with Smart Meter technology, rather than the energy monitors currently on the market. Our Development The starting point for this product was the design and testing of the user interface. Drawing on our extensive experience in inclusive design principles, we developed a range of interface designs and menu structures, which were evaluated initially in user testing via our interactive test tool. Multiple product concepts were developed for early assessment, and physical models produced using our in-house 3D prototyping system.

Prepaid Meter Products - View ePrepaid's Wide Range. Freescale and INSIDE Secure Revolutionize the Prepaid Meter. SAN ANTONIO--(BUSINESS WIRE)--Freescale Semiconductor (NYSE: FSL) and INSIDE Secure today announced a secure prepaid utility meter reference design with near field communication (NFC) connectivity that OEMs can use to quickly and cost-effectively bring to market electricity meter products.

Freescale and INSIDE Secure Revolutionize the Prepaid Meter

The reference design, based on the Freescale Kinetis MK30 microcontroller (MCU), provides the first NFC-based, prepaid meter with the ability to securely reload energy credit balances. “Through our collaboration with Freescale, we have been able to combine our leading security and connectivity solutions to protect prepaid meters while providing a more convenient way to load energy credits and deliver valuable usage information to utilities.” Utilities in many countries require a sophisticated payment infrastructure to facilitate the utility payment process while preventing fraud.

The reference design features INSIDE Secure’s VaultIC™ 460 and NFC (MicroRead® 3.4) chipset. How do Smart Meters work? - Utilita Energy: pre-pay the smart way.

Micro -grid is small power generation grid near to the consumers. It is mostly developed by private/independent organizations. In Jan 2012, over 300 million Indian citizens had no access to electricity. Over one third (33%) of India’s rural population lacked electricity, as did 6% of the urban population. Why Energy storage is important for micro-grids in India?

California approves shared renewable energy program

September 2013 | Global PV markets, Markets & Trends, Investor news | By: Ian Clover Approval of the largest program for shared renewable power in the U.S. passes in California, enabling schools, rental tenants and owners of homes in the shade to invest in solar energy projects. California's Green Tariff Shared Renewables Program is set to bring solar power to a larger share of the state's green-thinking citizens and organizations. Walmart California’s Legislature has given the green light for the state’s "Green Tariff Shared Renewables Program", which is the largest of its kind in the U.S. and will allow rental tenants, schools, cities and many other interested parties to invest in California’s renewable energy projects. The program gives businesses and individuals the option to switch to a 100% "Green Rate" at the utility, which guarantees that their energy use is tied to a newly built renewable energy system that the utility procures for all green rate customers.

No. 61/445,670 filed Feb. 23, 2011, the content of which is incorporated by reference. The present invention relates to storage-integrated management systems for energy microgrids. A smart grid is an interconnected system of information and communication technologies and electricity generation, transmission, distribution and end-use technologies that promise to enable consumers to manage their usage and choose the most economically efficient offering, maintain delivery system reliability and stability enhanced by automation, and use the most environmentally benign generation alternatives including renewable resources and energy storage. Energy microgrids are a key building block of smart grids. Energy microgrids can not only provide voltage and VAR support to the power grid but also reduce the emission footprint of the overall power generation infrastructure.
