Step dimming typically involves one or several output levels with the transition either being abrupt, as in switching, or a smooth fade. As daylight levels rise and fall, electric light levels fall and rise to maintain a constant light level, thereby saving energy. Daylight harvesting in an open office is a good example of where continuous dimming is advantageous. It is ideally suited to applications where we need transitions between light levels that are not irritating or disruptive to users. Continuous dimming enables light output adjustment across a range, with smooth transitions between each output level, resulting in a very high degree of flexibility to satisfy visual need. A simple example is a device that automatically turns the lights off (or reduces light output) when a space is unoccupied.ĭimming may be continuous or step. Switching is a simple, relatively economical control method well-suited to applications where a limited range of light-output levels is acceptable and where abrupt, noticeable changes in light level will not be irritating or disruptive. For example, a three-lamp fluorescent luminaire may be configured with a ballast that controls the outboard lamps and another ballast that controls the inboard lamp, resulting in a choice between outputs of 0 percent (off), 33 percent (one lamp on), 66 percent (two lamps on) or 100 percent (all lamps on). This allows a choice of two or more output levels from the luminaire or lighting system (in addition to no output) by assigning alternate lamps, ballasts or luminaires to different control outputs. Switching may be enacted as simple on/off, though a degree of flexibility may be gained through bilevel or multilevel switching. In both cases, the outputs are switching and dimming. Automatic control is generally driven by energy management, that is, saving energy by reducing or turning off the lights in response to conditions such as lack of occupancy or abundant daylight. These components and devices generate signals typically based on time, occupancy or light level. With automatic controls, the input is a signal automatically produced by another component or device, such as a computer, occupancy sensor or photosensor.

A good example is a meeting space where the lights may be raised to full during face-to-face discussion but lowered in part of the room for an audio/video presentation. Because the user initiates the control action, it is typically driven by applications involving output being adjusted based on a desire to achieve certain visual conditions.

Manual controls require a person to interact with them. The basic inputs are manual or automatic while the basic outputs are dimming and switching.

These functions may be integrated within a single device or enacted as a series of devices that are rated as compatible. The power controller then makes any required changes to the output of the controlled lights.
LIGHTING CONTROLS RESIDENTIAL APPLICATION SHADE CONTROL HOW TO
Based on its logic circuit, the lighting controller decides if and how to change output and subsequently signals the power controller. An input component or device provides information to a lighting controller. This article provides a brief introduction to how lighting controls work, resulting control strategies and how those strategies are applied to projects.Ī lighting control device or system operates on an input/output basis. Benefits of a good control design include reduced energy costs and flexibility, which can support the user’s visual needs and create a desired mood or ambience.
A good controls design, in turn, ensures that the lighting system produces the right amount of light where and when it is needed. The digital revolution in lighting control technology has enabled manufacturer solutions to keep pace with these demands.Ī good lighting design requires a good controls design.
In particular, commercial building energy codes are driving demand for more sophisticated, detailed and layered control systems. Growing demands for energy savings and flexibility to support visual needs have given lighting control much greater prominence. They either turn the lights on and off using a switch or adjust light output using a dimmer. Lighting controls are devices and systems that regulate the output of lamps and luminaires.
