LED Technology
A Light Emitting Diode (LED) is a solid-state semiconductor device that converts electrical energy directly into light. LED lighting is often referred to as “solid-state lighting”, describing devices that do not contain moving parts or parts that can break, rupture, shatter, leak or contaminate the environment.
Although the first LEDs were developed in the 1960’s, the technology remained limited to indicator lights for a few decades, due to its relatively low light output and narrow color range. LED light output and efficacy improved gradually over time, leading to signage and luminaires. Over the last few years LED technology has evolved from colored light to high performance white light, allowing for illumination.
White LEDs: There are currently two ways to create white light with LEDs. One method mixes multiple wavelengths of different LEDs to make white light (i.e. RGB); allowing the user to tune the white light through a controls system.
The second method uses a blue LED chip coated with a phosphor to create white light. This is the most commonly used method for general illumination with white LEDs and this is the technology used in Mundo Illumination’s products. This method offers a choice of color temperatures and results in simple product, easily installed in architectural projects.
