Response Daylight
An incredibly simple and affordable way to incorporate daylight controls into your lighting designs.
Response Daylight Applications
Understanding control zones
A good daylight controls design should leverage daylight contribution without disrupting occupants or sacrificing lighting quality. Here, it is important for designers to understand how daylight behaves in a space. Obviously daylight varies over seasons, throughout the day and even with passing weather. Daylight levels also experience a gradual fall off as you move away from windows into the space. The amount of available daylight is further affected by the size and glazing of windows, room reflectances and desk and ceiling heights.
When designing with daylight controls, it's a good idea to create multiple control zones within the space to compensate for differences in available daylight and to satisfy light level requirements for different functional tasks. Each zone should be controlled by its own daylight sensor, optimally placed over a representative work area.
In this example, two control zones have been created in the area where there is adequate daylight contribution, and one non-controlled zone where daylight is negligible. As daylight contribution increases, sensors can reduce electric light output on a relative, compensating scale.
Best Practices
Optimal sensor placement
- between 6’-10’ from window
- over representative work areas; avoid placement over dark carpet
- at least 5’ between each sensor
Daylit zone
- 15’ away from window*
*NOTE: The size of the daylit zone is primarily a function of the size and exposure of windows. In a typical space, areas beyond 15' do not usually receive enough daylight contribution to warrant controls. Within the daylit zone, designers can create multiple control zones depending on the design of the space and tasks being performed.
Suspended Applications
Ledalite's suspended products with Response Daylight offer architects and lighting designers critical flexibility and functionality for designing spaces with daylight control.
Ledalite suspended luminaires are themselves highly flexible, modular lighting systems designed for a wide range of applications and layouts. Most luminaires are available in 4ft, 8ft and 12ft modules with a range of lamping options (1 - 4 lamps depending on the product). Different modules can be joined together to form continuous runs of various lengths.
When integrated with Response Daylight sensors, Ledalite suspended lighting systems can be configured to accommodate almost any application. Response Daylight-controlled modules can be combined with non-controlled modules in a wide variety of configurations.
Recessed Applications
Ledalite's recessed luminaires with MesoOptics® technology are a natural fit for architects and lighting designers who want to bring the best of nature's luminous aesthetics to indoor environments.
These innovative luminaires provide unique optical control capabilities, exceptional visual comfort and dramatic energy savings over conventional recessed systems. They are available in a range of sizes and lamping options and can be installed in continuous rows or as standalone units in a grid.
When integrated with Response Daylight, these luminaires provide even more energy efficiency while also offering design flexibility and simplicity for your daylighting designs. Sensors can be integrated in standard 2x2 and 2x4 luminaires and configured to accommodate virtually any sensor placement and zoning requirements. A single recessed fixture with a Response Daylight sensor can control all lamps in up to 19 additional standard dimming fixtures, minimizing controls costs and maximizing energy savings.
