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. 

Color tuning is often used for purely aesthetic purposes—creating lighting “scenes” or particular atmospheres. However, research suggests it could find a new home in healthcare facilities.

As demand for LED lighting and controls increases, the lighting world is becoming more complex, which raises demand for expertise to produce good lighting solutions. Unlike other professions, lighting designers do not require state licensure.

A suitable application for tunable white lighting is in classrooms. The system used in the room shown above offers four settings. In “calm” mode, the lights are set at a standard intensity level and warm shade of white light, oriented toward calming an excited class.

The color appearance of light sources can have a major impact on how people perceive spaces. In high-end retail, hospitality and similar applications, color temperature choice is a critical design decision.

Crops, of course, have always relied on three things from nature: soil, water, and sunlight. If executives at AeroFarms have their way, though, the future of crop growing will be mesh cloth, small amounts of water, and LED lights.

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.

General lighting in a living room should fill the space with a subtle warm glow to make it feel inviting and comfortable. The general lighting can be a visual element to personalize the space, such as a chandelier, or blend in with the architecture, such as recessed downlights.
The Light Within

Residential interior lighting is as much art as science. A good residential lighting design is functional and comfortable, blends with the architecture and decor, and helps the owner personalize their home. The result is experienced as work, leisure, living, showcase, castle and sanctuary.
