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.
Lighting Controls Association Announces Update to Dimming Course
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.
Steve Mesh Talks Dimming Curves, Part 2
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.
Steve Mesh Talks Dimming Curves, Part 1
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.
HLB’s C. Webster Marsh and Adam Levine on Digital Lighting Control Protocols
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.
HLB’s Elizabeth Johnson and C. Webster Marsh on Analog Dimming
“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.
Avoiding and Resolving Issues with Products That Don’t Dim as Expected
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.
Dimming Lamps and Luminaires
Eaton’s The Lighting Resource recently published an article about dimming LED lamps and luminaires.
Dimming TLED and LED HID Replacement Lamps
When evaluating an existing lighting system, the owner can do nothing, something or everything. Doing nothing abandons operating cost savings. Doing something entails replacing lamps and installing some automatic controls. Doing everything involves installing a new lighting and control system. As many owners opt for the “something” option, demand for LED replacement lamps continues to […]
The Twisted Road of Dimming Curves
Guest post by Kevin Willmorth. Superficially, dimming seems to be a simple operation. Turn a knob, slide a bar, or touch a screen to change light levels – done and done. This simplistic form of dimming was once applicable to resistance loads (incandescent lamps) using rheostat controls. The combination creates a naturally feeling dimming profile, […]
