In your home, lighting may be 10 percent of your bill. But in an office building it’s probably 40 percent, and so if you reduce your lighting energy consumption by a large fraction, the savings will be huge,” said James Brodrick, who leads the DOE’s solid-state lighting program.
A fact sheet from Brodrick’s office says this [...]
As we all know that LED technology shows great promise in lighting the way for Tech to a more economic and environmentally-friendly direction.
Facilities faculty has completed several lighting renovations already on campus, including converting all the lighting in the Tennenbaum Auditorium to LED lamps. This project alone reduced electricity consumption by 39.2%, and light per [...]
As we all know that the future of energy efficient lighting is LED. Not only are LED’s environmentally friendly, the light represents a true white light. A recent press release printed in the Village News on ways to cut energy expenditures missed the mark completely.
Although it is true that CFL bulbs do save energy, they [...]
A diode is the simplest sort of semiconductor device. Broadly speaking, a semiconductor is a material with a varying ability to conduct electrical current. Most semiconductors are made of a poor conductor that has had impurities (atoms of another material) added to it. The process of adding impurities is cal doping.
In the case of LEDs, [...]
LED (Light Emitting Diode) lights attract a great deal of attention as “a light for the 21st century”. This is the field where the market is fast growing as the LED light can be an alternative light source to a conventional incandescent bulb and fluorescent bulb. Compared to an incandescent lamp (bulb type), LEDs have [...]
The same innovation that makes laptop screens thinner turns out to be one of the best energy-saving technologies on Earth – and it’s all thanks to new tricks that make it possible to create more illumination using the most humble member of the semiconductor family, the light-emitting diode, or LED.
Semiconductors, you will recall, are materials [...]
1. Bad Color Rendering
Currently, a white LED produced from a blue LED covered with yellow phosphor generally has bad color rendering (below 80%), as the emitted light lacks red and does not restore this color correctly. But a TL tube or a compact fluorescent lamp may have color rendering indices from 80% to more than [...]
The technology of LED is able to convert electricity with virtually no waste heat.
The acronym stands for light emitting diode, and this technology uses a tiny fraction of energy consumed by conventional incandescent and fluorescent bulbs for a given amount of light. The working life of LED lights is measured in tens of thousands of [...]
For 100 years, UC Davis has engaged in teaching, research and public service that matter to California and transform the world. Located close to Sacramento, UC Davis has 31,000 students, an annual research budget that exceeds $500 million, a comprehensive health system, and 13 specialised research centres.
California Lighting Technology Center (CLTC), within the Design Program [...]
