We can see at last!

With the days being a little gloomy recently we decided it was a good to time to start thinking about the lighting. This has been a tricky task as you never really know how much light you may need, but it is rather expensive so getting too much in would be wasteful. 254 more words

Light Quality Metrics: Color Rendering Index

Color rendering is defined by the International Commission on Illumination (CIE) as the “effect of an illuminant on the color appearance of objects by conscious or subconscious comparison with their color appearance under a reference illuminant”. 561 more words

How do LEDs work?

LEDs generate light by electroluminescence, which is the phenomenon of a material emitting light when electric current is passed through a semiconductor diode. This causes the semiconductor material to emit light at a wavelength determined by the energy band gap of the semiconductor. 329 more words

The Future of Lighting: Smart Lighting?

The potential benefits of smart lighting are manifold; the lowest hanging fruit being increased energy savings. As a consequence, most works in this fledgling field of study are currently focused on extracting maximum energy savings from smart lighting systems in conjunction with efficiently driven LEDs. 437 more words

LED Lighting Today

Today, the global lighting market generates an annual revenue of nearly $100 billion, with LED products accounting for roughly 18% of the total lighting revenue. In 2013, the use of LED products doubled to 105 million units in the United States alone, while the estimated annual energy cost savings due to LEDs increased to $1.8 billion. 357 more words

The History of Electrical Lighting

Electrical illumination. It all began when experiments were first conducted by Sir Humphry Davy in 1801, who created the very first incandescent lamp prototype by demonstrating discharge between two carbon rods and a glowing piece of wire heated by electric current from a copper-zinc battery. 496 more words

ESD Issues for Placing SMD LEDs

Electrostatic Discharge (ESD) can cause damage to unprotected electronic devices even when the discharge can be at times imperceptible. Even though all LEDs are susceptible to ESD damage it is the GaN based LEDs (blue, white and some green colors) that are more sensitive to surge voltages caused by ESD. 192 more words
