High Bay Sensor Technology
High Bay Sensor Technology
Many industrial LED high bay lights are equipped with multifunction motion sensors. This latest feature has become more popular as it reduces the electricity bill while ensuring that the light stays on only when people or living things move around in the room.
A qualified electrician should perform all installation and maintenance per local, state, and national electrical codes and requirements. Before starting, de-energize the fixture and sensor.
Occupancy Sensors
Occupancy sensors are smart systems that automatically turn on lights and HVAC equipment when someone enters a room and turn off when the space is empty. This automation allows teams to optimize workspaces and deliver a more engaging employee experience.
They provide immediate insight into real-time usage across a space, allowing leadership teams to make the right changes to maximize ROI. Occupancy sensor insights also support renovations, expansions and rightsizing efforts to ensure the best value for every square foot.
These self-contained devices mount directly to an industrial luminaire or electrical junction box and control 0-10 VDC drivers or dimming ballasts. They feature digital PIR motion detection architecture and dual element passive infrared (PIR) technology to improve detection coverage for high ceiling mount applications up to 40 feet.
Battery-powered PIR sensors use standard 3-volt C123A lithium batteries and can last up to 12 years. Some offer a choice of operating schedules and vacancy mode to meet the needs of specific use cases. Some models come with built-in Fresnel lenses that amplify their sensing range to cover large areas. Some wired sensors have a power pack that provides line voltage to the fixture; others require a power cord.
Occupancy sensors that require a power cord typically have a 15-30 second time delay to allow Intelligent power supply for motion singles to activate the lights before they turn on, and to prevent the sensor from being triggered off by movements once it’s inactive. The user-adjustable time delay setting lets you choose your preferred vacancy window period.
Motion Sensors
Using motion sensors is a great way to conserve energy in your commercial or industrial facility. These sensors turn on lights and other energy-consuming devices only when someone is moving around the room, then automatically shut them off again after a predetermined time. This saves money on power bills, and it also reduces the impact of your lighting system on the environment.
There are several types of motion sensors on the market, but they all work in similar ways. PIR (passive infrared) sensors use thermal images to detect movement, but some offer adjustable sensitivity settings so you can fine-tune how sensitive they are. Ultrasonic sensors, on the other hand, emit sound waves that bounce off objects in their vicinity and return to the sensor. The sensor measures the return time to determine how far away an object is.
Many motion sensors combine PIR and microwave technology to provide the best of both worlds. Microwave sensors draw less power than PIR, and they can be used to verify that an intruder has been detected by the PIR sensor. These are often used in lobbies and other areas where there is a lot of motion. Some of these motion detectors also activate security cameras when they detect movement, allowing home and business owners to see who is at the door from their smartphones before answering.
Photocells
Photocells are a type of semiconductor that converts light into electricity. They work by detecting changes in the photoelectric effect, which occurs when light hits a semiconductor and causes electrons to move inside it. The change in electrons can cause current to flow, which is the same process that happens in solar cells and LEDs.
Photoelectric cells are often used in lighting systems to automatically turn lights on and off as the sun goes down or rises. They’re also common in outdoor settings for things like parking lot lights, street lights, and illuminated business signs. You can use a plug-in photocell to connect to a standard outlet, or you can screw a lamp base version into a bulb socket and turn almost any fixture into a dusk-to-dawn light.
Most photocells have a peak sensitivity for visible radiation around the red or violet end of the spectrum. Some, especially silicon photodiodes, have a peak sensitivity for invisible radiation in the ultraviolet or infrared range.
When using a photocell with your high bay fixtures, be sure to inspect the device over time for cracks that can cause it to malfunction. When a photocell is cracked, it can no longer convert light into electric current. Over time, this can result in intermittent lighting or no light activation at all. If you notice any cracks in your photocell, they must be replaced.
Timer
Timers are used to measure the elapsed time and keep the operation of the embedded system in sync with the clock. They are also used to generate delays and help in the iteration of various loops for a specific range of cycles. They are easy to program and take the place of different loop iteration methodologies.
Multifunction motion sensor high bay lights come with a built-in timer that lasts for 30-45 seconds. After the living thing surpasses the detection range, the light automatically turns off. This is an efficient way to reduce energy consumption and save money in the long run.
The sensor controls 0-10 VDC LED drivers or dimming ballasts and offers three-level control based on movement. It has a built-in High Bay Sensor timer that can be set to turn the light ON at a minimum dim level for a period of time known as Partial OFF Time (T2). When T2 expires, the lights will switch OFF.
The IR-TEC LOS-502SEC occupancy sensor features an advanced quad element pyroelectric passive infrared technology to detect occupants and their movements. It is suitable for commercial and industrial lighting fixtures with a 1/2 inch knockout. The sensor can be installed either in the ceiling mount or in a junction box and works with a wide range of 120-277 volt line voltages. The DIP switches allow the user to configure the sensor for maximum power efficiency and to select a desired time delay.
