Using Lighting Controls for Additional Energy Efficiency
- Using Lighting Controls for Additional Energy Efficiency
Using lighting controls can help you reduce your electricity bills more than simply using energy efficient lighting alone. Lighting controls are things like motion detectors, timers, occupancy sensors and daylight sensors. On this page we are going to focus on occupancy sensors and daylight sensors because these types of sensors can work very well in a setting where a simple timer won’t be effective.
Daylight sensors do exactly what it sounds like they do, they detect the amount of ambient light and they will turn on the lights when the ambient light is below a certain level and they will also turn off your lights automatically when there is sufficient ambient light. Simply turning your lights off when they are not needed will save you a lot of electricity and daylight sensors will take care of that for you automatically.
Occupancy sensors are able to detect when a person is in a room and they will turn the lights on automatically when someone enters a room. They will also turn the lights off automatically when people have left the room. Occupancy sensors use a couple of different technologies to detect when someone is in the room. Passive infrared technology (PIR) allows the sensors to detect the difference between the amount of heat being emitted by a person versus the ambient heat in the room.
Occupancy sensors may also use ultrasonic sensors that send out sound waves into the room and then measure the speed at which the sound waves return to the sensor. These ultrasonic sensors are able to measure frequency changes caused by people moving around in the room. Sensors that use PIR technology must have a direct line of sight between the occupants and the sensor. Ultrasonic sensors are able to cover an entire room and do not require line of sight. They are able to detect people even when they are behind obstacles and they are very sensitive to minor movements.
These types of lighting controls can be very useful in a number of situations. Occupancy sensors can be very useful in conference rooms, bathrooms, storage areas etc. Areas where people are going in and out fairly often. However, these types of lighting controls are not going to be useful for some applications. For example, you may have a warehouse that doesn’t receive very much natural light and people may be working in that area 24 hours per day. That is a situation where you simply need to have good, efficient lighting that will be left on most of the time. If you are in need of efficient lighting for a commercial or industrial setting we can help. At http://hibritelighting.com/ we have incredibly efficient T8 fluorescent lighting and we can even provide you with a free energy analysis to help you find solutions to your lighting situation and help you reduce energy costs.
