WBS intelligent sensor-dimming LED lighting solution

  • What’s the solution?
    – At WBS we have developed a proprietary solution that will allow you to save more than 80% of your lighting electricity costs for your Car park, fire stairs, corridors and common areas.
  • How does it work?
    – By using a combination of proprietary movement sensor and dimming technology paired with LED Emergency and Non Emergency batten lighting in both 2 and 4 foot.For example, sensors and LED lights are installed in a car park. The car park lighting under control of the sensors is normally dimmed to 20% of full luminance when no persons or vehicle movements are detected in the car park. When persons or vehicles enter or move in the car park, the sensors via a secure wireless link communicate with a specialised module in the lights and intelligently bring the car park lights to 100% luminance.
  • Can this sensor dimming system be overridden?
    – Yes, we have designed a remote control unit for building/facility managers or committee members to override the system during the traffic peak usage times or when the building is under maintenance work.
  • What about safety and compliance?The system complies with the following Australian standards
    • AS2293.1-2005   Emergency Escape Lighting and Exit signs for Buildings – System Design, Installation and Operation.
    • AS2293.3-2005   Emergency Escape Lighting and Exit Signs for Buildings – Emergency Escape Luminaries and Exit Signs
    • AS1680.0-2009   Interior Lighting – Safe Movement
  • What’s WBS solution unique advantage?
    – A significant feature that sets WBS intelligent sensor-dimming LED lighting solution apart from others in the marketplace is the seamless operation of the lighting. Because it’s a network sensor system, the person or vehicle entering the Car Park or person entering the Fire stairs will not even know that the lighting has been dimmed. The lights under control will be fully on area by area (normally at radius of 30 meters), the person will feel much more confident and comfortable walking in the car park with the lights under the network control system compared to a standalone scenario.
  • How much electricity does it save?
    – In a car park, it saves about 82% of your electricity usage if the lights are fully on for 20% of the time and on standby for 80% of the time;In the fire stairs, it saves about 88% of your electricity usage if the lights are fully on for 5% of the time and on standby for 95% of the time;
  • What wattage does it dim to?
    – The LED lights will dim to 10% of the existing fluorescent light power consumption. For example, the new LED replacement for a 2 x 36W Fluorescent tube will dim to 2 x 3.6W.
  • Can it be turned off completely?
    – No, the lights under this system cannot be turned off completely. WBS never turn off the lights at common area, because of the OH&S and security reason.
  • Does surveillance camera system still can record clear video when all the lights have been dimmed down?
    – Yes. When all the lights have been dimmed in the car park, WBS lights still remain 16 Lux on the ground. Surveillance camera still can record very clear full colour video.
  • What kind of lights can be used in the system?
    – LED emergency and non emergency batten light -2 foot or 4 foot, single or twin, standard or weather proof; LED oyster emergency or non emergency light; LED down light – 8 inch or 3 inch.
  • Are they easy to install? Is there any extra wiring needed?
    – Yes, WBS lighting is designed for easy installation and all the sensors receivers are plug and play, no extra wiring or cable needed.
  • Is it limited to car parks and fire stairs?
    – Car parks, fire stairs, corridors, lift lobbies or any other building common areas can use this system.
  • Do the lights brighten up immediately or is there a delay?
    – When movement is detected, the lights will brighten up immediately and there is no delay.
  • Do all the lights have/need sensors?
    – No, the lights will need either sensor or receiver to work in this system. One sensor can signal all the surrounding lights at the radius of 30 meters to turn on.
  • Can all WBS lighting products be used for this solution?
    – Almost all WBS lighting products can be used in this system, except WBS LED EXIT lights, spitfire emergency lights and flood lights.
  • Does the process of dimming down the lights affect the life span of the light?
    – Yes, in a positive way! With the system running at 20% luminance, the lifespan of the LED light is increased to approximately 10 years.
  • What if the sensor fails?
    – In case of any sensor failures, the lights under the control of that specific sensor will remain dimmed. The 20% luminance level is twice the minimum level required for safe passage of persons.
  • What’s the difference between a PIR and MW sensor?
    – A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. WBS use PIR sensors in fire stairs because the sensor won’t pick up movement outside the door, which helps to achieve the best system saving.Microwave sensors send out ultra high frequency sound waves, and detect the reflections. WBS use microwave sensors in car park as they are more sensitive and has longer monitoring distance; this will ensure the best system performance.
  • Why is the maintenance cost for WBS LED Solution so low?
    – Dim down technology means that WBS LED tubes are always working on a very light load. For example 90% of the time WBS LED tubes are only working at 20% brightness. Using WBS dimming technology the life of LED tubes will be extended much longer. Furthermore, all WBS products are designed using modular technology. When one of the WBS LED light fittings fails, the customer can just replace the faulty module and not the entire fitting. This ensures the whole lighting system is a very cost effective solution.
  • Does WBS LED light have different color temperatures?
    – Yes, WBS LED lights have 3500K warm white color and 5000K cool white color to suit different location and requirements.
  • Would turning the lights off (rather than dimming) save even more energy?
    – This is from our lovely assistant accountant Jenny, actually it’s a very good question. Yes, turning the lights off will save even more energy, however it’s illegal to turn the lights off in fire stairs when there is no natural light; I know in some car parks, the lights are turned off by sensors, but in case  the sensor fails, people will be left vulnerable and unsafe walking towards the dark.
  • Should we explain the difference between LED and fluorescent lights? Or just let our customers search it up themselves?
    – Thanks Jenny, as you mentioned, please see the below difference between LED and fluorescent light: An LED lamp is a light-emitting diode (LED) product that is assembled into a lamp for use in lighting fixtures. LED lamps have a lifespan and electrical efficiency that is several times better than incandescent lamps, and significantly better than most fluorescent lamps, with some chips able to emit more than 100 lumens per watt.Like incandescent lamps but unlike most fluorescent lamps (e.g. tubes and compact fluorescent lamp (CFL)), LED lights come to full brightness without need for a warm-up time; the life of fluorescent lighting is also reduced by frequent switching on and off.  More
