Control zoning is an important aspect of lighting control system design, as zoning is the mechanism through which lighting controls are assigned to lighting loads. A control zone is defined as
one or more light sources controlled simultaneously by a single control output
.
What is the purpose of lighting control?
Lighting controls are a range of smart lighting devices that
can regulate the levels, quality and characteristics of light in a defined space
. These smart devices aid in reducing electricity wastage while simultaneously encouraging energy efficiency.
What are lighting zones?
Lighting zones
reflect the base (or ambient) light levels desired by a community
. The use of lighting zones (LZ) was originally developed by the International Commission on Illumination (CIE) and appeared first in the US in IES Recommended Practice for Exterior Environmental Lighting, RP-33-99.
What are lighting control devices?
Lighting control systems are
a networked system of devices related to lighting control
. These devices include relays, occupancy sensors, photocells, light control switches or touchscreens and signals from other building systems (such as a fire alarm or HVAC).
What is lighting control called?
A lightning arrester (alternative spelling lightning arrestor) (also called lightning Isolator)
is a device used on electric power transmission and telecommunication systems to protect the insulation and conductors of the system from the damaging effects of lightning.
What is the basic principle of light control?
The
absorption of light
occurs when a ray of light strikes a surface. The energy from the light is transferred to the surface material. During absorption, the energy may change from one form into another. An absorbing surface prevents reflection or diffusion of light striking on the surface.
How do lighting control systems work?
The lighting controller evaluates
input control signals based on its algorithm and decides whether to adjust lighting power
, when to adjust it, and by how much. The controller may be installed as a logic circuit within a standalone control device or as a separate component within a control system.
What does Zone 1 and 2 mean in bathroom lighting?
Zone 1 is the area above the bath or shower to a height of 2.25m from the floor
. … Zone 2 is an area stretching 0.6m outside the perimeter of the bath and to a height of 2.25m from the floor. In this zone an IP rating of at least IP44 is required.
How many lighting zones are there?
The Commission Internationale de l’Eclairage (CIE) has outlined
four
environmental zones to establish a basis for outdoor lighting regulations (CIE 1997). The environmental zone rating can be used to help ensure that the lighting goals of an environment are appropriately defined and met, but not exceeded.
What are dust lights?
Zone 1 – Dust/Fog: This zone
illuminates the area directly in front of the vehicle
. … These lights are mounted towards the middle of the front of the vehicle to avoid glare off of the hood/fender or from dust and fog.
What are the types of lighting control?
In general, there are three types of lighting control systems.
There are dimmers, sensors and timers
. Each has different purposes and features. Learn all about the different kinds to see which is right for your building.
What are the two methods of lighting control?
There are two types of lighting control
analogue and digital
.
What are the different types of lighting control systems?
- Basic lighting controls. …
- Pre-set lighting controls. …
- Dimmer switches. …
- Occupancy sensors. …
- Motion sensor controls. …
- Assisted lighting controls. …
- Integrated lighting controls.
What is the control of electricity?
An electrical control system is
a physical interconnection of devices that influences the behaviour of other devices or systems
. A simple electronic system is made up of an input, a process, and an output. Both input and output variables to the system are signals.
What is the first basic principle of light?
The First Basic Principle of Light
‘Light is
a form of energy’
When light reaches a surface, it can be absorbed and transformed into other types of energy.
What are the 3 principles of light?
In photography, there are three main principles:
instensity/quantity of light, direction of light, and quality of light
.
