Introduction to LED Lighting



This is the first in a series of articles that will talk about LED Lighting. In future articles we’ll be discussing the technology of the LED, where it came from and why LED lighting design is set to become the predominant source for good quality illumination.

A few basics, then: LED stands for Light Emitting Diode. It’s a completely different type of light source, having its roots in electronic circuitry. LEDs have been used in the dashboard displays of motor cars for many years, and as the indicator lights that we see in our electrical equipment. The architectural lighting LED, however, can better be described as a ‘Hi LED’ as a result of the huge improvements that have been made in the light output.

So why LED Lights, and how do we get the best out of them? Here are a few of the advantages that LEDs have over ‘conventional’ light sources:

1. Being the size of an electronic component rather than a ‘light bulb’ means that the LED opens up many new possibilities in lighting design.

2. The efficiency of the modern LED gives it official ‘low energy lighting’ status, with many (but not all!) LED fixtures meeting the requirements of Building Regulations Part L: Conservation of Fuel and Power.

3. The colour quality of the LED makes it an excellent source for all kinds of display lighting. The question of light colour quality is often ignored, compared to the issue of energy conservation, but it’s actually a very important factor in assessing the real quality of a light source.

This raises the vitally important subject of colour rendering, which is the index used for a light source’s ‘colour accuracy’. Good lighting requires white light to have a high colour rendering index, at least better than 0.8 and as near to 1.0 (the ideal measure) as is practicable (and cost effective!)

At the end of each of our blogs, we’ll be offering you:

Energy Conservation Tips – Automatic lighting control.

The lighting in many service and utility spaces is often controlled by a simple wall switch, relying on the ‘last person out’ to turn off the lights.Consider replacing, or over-riding that switch with a presence detector that will automatically switch off lighting when there’s no one in the room.
