Many designers, manufacturers, and contractors are resisting change, Marsh notes in his column, and it appears as though we are headed towards a third paradigm shift that will sustain those who adapt and eliminate those who don’t.
Moderated by Michael Colligan, this episode of Get a Grip on Lighting pits two lighting thinkers in a spirited debate over whether 0-10V or digital lighting control has the edge in projects subject to value engineering.
0-10V dimming wires, the wires used to communicate dimming intensity via a 10-volt signal, can be easily identified on wiring diagrams, installation instructions, and dimmable drivers by their colors: gray and violet (although violet is often referred to as purple). This will soon change, however, as new codes and guidelines take effect.
The Lighting Controls Association (LCA) has updated EE103: Dimming Controls, Section 1 Part 2: Dimming Controls and Systems, a popular learning module in its Education Express program.
Different types of dimming curves may be incorporated in dimmers, software for lighting control systems, and output devices like LED drivers irrespective of the actual protocol used to communicate between them.
Let’s talk about dimming and dimming curves, and a variety of attributes that you should consider, inquire about, then specify what you actually want.
C. Webster Marsh, Designer with lighting design firm Horton Lees Brogden Lighting Design, provides the final installment on his series of articles about dimming and lighting control protocols. In this last installment, he teams up with HLB’s Adam Levine to tackle digital control protocols, covering when and how to specify it, and how to overcome some of the challenges.
“Communication is key to ensuring compatibility between controllers and drivers,” write Elizabeth Johnson, Senior Associate, and C. Webster Marsh, Designer, of Horton Lees Brogden Lighting Design in an article about analog dimming.
With the right combination of dimmer and solid-state driver for LED products, dimming performance can achieve excellent results from 100% all the way to dark, smoothly and predictably, says Kevin Willmorth in his latest exclusive contribution. However, when the combination is wrong, many undesirable effects may occur, he points out. Investigating the reasons for these issues requires a basic understanding of where issues can arise.
Eaton’s The Lighting Resource recently published an article about dimming LED lamps and luminaires.
