What are lighting zones?
PoE Lighting Zone Controls, zones simply mean the areas or group of lights you wish to use together. Zones allow you to control more than one light or lighting area at the same time, meaning you don’t have to go around individually controlling each light separately.
What is single zone lighting control?
Luminetworx single zone lighting control is the ability to control lighting in one area. For example, if you have multiple areas of lighting in a room but would be satisfied with controlling and dimming all the lights together, you can use single zone lighting control.
What is multi zone lighting control?
Luminetworx multi zone lighting control is a system that allows you to control different areas of lighting individually. This would be useful if you have installed lighting into several areas of a room but do not always want to have each fixture on or off at the same time. For example, if you install task lighting areas as well as ambient lighting in a room you would need to have the ability to turn the ambient lighting on separately from the task lighting to create a soft and relaxing atmosphere in a room.
PoE Lighting zone control is just one more feature of the Luminetworx PoE Lighting system. Lighting controls are the primary means of providing lighting functionality and saving lighting energy costs. At the most basic level, the lighting control system design must be in compliance with the most recent edition of ASHRAE 90.1 for the associated jurisdiction. The following strategies (or a combination of strategies) can be incorporated to achieve a compliant design:
- Time/astronomical scheduling: Lighting in a defined area turns on or off, or dims, based on a predetermined, customizable schedule.
- Occupancy/vacancy control: In each zoned area of the building, lighting is turned on, off, or to a predetermined level based on detected occupancy. With “vacancy” control, users must manually turn on lights, but lights are automatically turned off when a space becomes vacated. Often, room conditions may not require electric lighting, as in the case of a day lit office. In this type of situation, vacancy sensors are able to save energy that would have otherwise been automatically consumed if an occupancy sensor forced the lights on. For this reason, vacancy sensors are generally considered more efficient, therefore preferable to, occupancy sensors, driving the inclusion of prescriptive vacancy sensors in many versions of updated electrical codes.
- Daylight harvesting: Light levels are manually and/or automatically adjusted based on the amount of natural light in a space. Appropriate light levels are provided for functional purposes, and total illumination is maintained throughout the space. Different ways of harvesting daylight include continuous dimming of the lighting systems (the most efficient option), bi- or multilevel zone dimming or switching, or simple on/off controls provided for lighting zones where ample daylight is expected.
- Task tuning: Maximum light levels are set or “tuned” for a particular use or task in a specific room to prevent over lighting and to extend the life of the lighting system.
- Personal control: Individuals can tailor the lighting in their workspace to their personal preferences and needs. This can be achieved by giving each user control over the lighting system in a granular way, or by employing a task/ambient lighting strategy and providing an individual task light at each workstation.
- Control of emergency egress lighting: In the past, lighting on emergency circuits was often left “on” 24/7 as a safety measure, burning through the night long after occupants of a building had left. Advances in control devices now allow emergency lighting circuits to be controlled by time schedules or automatic sensors. By equipping these devices with a UL 924 emergency transfer device that can override the digital lighting control system if normal power is lost, the system is able to turn on all lights connected to the emergency circuit and maintain egress levels for occupant safety—without wasting energy.
