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. 

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.

Replacing the driver


The majority of LED lighting products use an electronic driver that functions similarly to a fluorescent ballast. The driver converts incoming alternating current (AC) to direct current (DC) and drives this current to the LEDs.

For a long time, the lighting industry relied on conventional, legacy light sources and traditional designs. Recent advancements in LED technology, however, have changed the face of the industry in terms of the form and function of luminaires.

Flicker in light sources is an old problem made new again in the LED age. Its effects range from annoying to debilitating, and solving it can be challenging. Even defining flicker is difficult.

Hard Numbers: Responsive Lighting

Estimating lighting control energy savings is challenging, as actual savings depend on application characteristics, such as occupant behavior, building design, site orientation, daylight apertures, interior reflectances, device settings and level of commissioning.

The Right Light: Color Tuning

While light makes sight, lighting shapes perception, particularly in regard to color in the things we see. This is because visible white light is made of colors. For us to see an object as a certain color, that color must be present in both the light and the object.
