Lighting

 

 

Lighting and controls is a huge, constantly changing, dynamic market. The ELECTRICAL CONTRACTOR lighting editorial listed below keeps current on technological innovations from LEDs, controls, and design to innovations in efficiency by traditional lighting formats. 

For the ease light-emitting diodes (LEDs) can offer in providing an effective, low-draw and energy-efficient lighting solution, the considerations to their use are many. The best service you can provide is a bit of mythbusting regarding true LED end-of-life.

The market for light-emitting diode (LED) products and technology is more attractive than ever because of energy-conservation concerns and lower maintenance costs. Until now the cost wasn’t attractive enough for broad appeal. 


Looking beyond the apps


In the not-too-distant future, 
a time may come when electrical contractors will entertain their grandchildren with tales of lighting fixtures that existed for the sole purpose of illumination.

While the light-emitting diode (LED) has gotten a lot of attention in recent years, another revolution has quietly developed in the background: intelligent (digital) lighting control. The future of lighting is solid-state, and it will be highly controlled.

In the Driver's Seat: LED Drivers

The LED driver acts as a power supply for LED modules, regulating output voltage or current for the light source. It transforms and conditions incoming power (typically AC, but it may be DC) and drives the current to the LEDs.

Day And Night

Daylight may enter a building by way of toplighting (e.g., skylight) or sidelighting (e.g., window) apertures. Good design enables diffuse daylight to serve as a primary source of general illumination while avoiding glare and heat gain.
