The $10 LED Lightbulb
Of course, there never really was a “war on lightbulbs,” nor was there ever any ban on incandescents… but there was, certainly, a lot of hype about what a weak substitute Compact Fluorescent bulbs are for good old fashioned, energy-sucking Incandescent bulbs. Finally, it seems a viable and likable alternative has emerged: affordable and attractive [...]
In Focus: GaN-on-Si LEDs
Plessey Semiconductors has announced earlier this month that samples of its LED products using gallium nitride (GaN) films on 6-inch silicon substrates are now commercially available for sampling, which is the first of its kind across the industry. The development of comparable quality LEDs on silicon substrates to current standards is considered a holy grail [...]
Light Bulbs: What Does The Future Look Like?
It shouldn’t come as a surprise that you missed a major change in light bulb manufacturing as you danced beneath New Year’s Eve disco balls, toasted each other and sang “Auld Lang Syne.” Nevertheless, the traditional song could have been dedicated to 100-watt incandescent light bulbs. As of January 2013, 100-watt incandescent bulbs can no [...]
150K Solar Street Lights Planned in Mecca
The scale of this solar street lighting project in the Saudi Arabian holy city of Mecca is truly breathtaking. However, what is even more breathtaking is the conclusions can one draw about the value proposition of solar in a place where oil generated electricity comes in at a mind numbingly low 0.006 per kilowatt hour. [...]
The 100K Solar Lantern Project Announced by Panasonic
Panasonic Corporation is set to distribute 100,000 solar L.E.D. lanterns to people in electricity scarce regions across the world by 2018 to mark the company’s centennial anniversary. The 100 Thousand Solar Lantern Project aims to help address many of the problems in non-electrified areas by using solar lanterns that can generate electricity from sunlight during [...]
Why Solar Lighting is the Future
Solar energy has been harnessed by humans for thousands of years. From the earliest times, our ancestors used the sun’s energy either to heat their bodies or to dry food and clothes. But it has only been in the last two centuries that we have begun using solar energy to produce electrical energy. The discovery [...]
In Focus: The LED Revolution
Initially just an innovative way to provide the lights on indicator lamps and remote controls, and then developed into an exciting way to add colour to interior design projects and modern venues, the light emitting diode is now wending its way through the lighting market on an eco-warriors mission to replace the standard incandescent bulb. [...]
HUGE: Los Angeles Converting All Streetlights to LEDs
In the largest street lighting retrofit ever undertaken by a city, Los Angeles is in the process of converting its 210,000 street lights to energy efficient LEDs. Although the idea of switching the kind of lighting used may seem boring, street lights are responsible for 40% of cities’ energy bills, according to Pike Research, … and therefore, energy consumption. [...]
