The Sensing Distance of a LED module refers to the device which detects the surrounding and other external factors of the module. This is an important feature of the LED module because it will be activated to ensure better energy efficiency and where necessary ensure that no energy wastage happens.
This feature is actually invoked by a sensor which is usually attached to a LED bulb or a tube. It usually uses Infrared technology to scan its surroundings before changing the lighting or intensity of the light. In most cases, the LED light is programmed to emit lesser light if the surroundings are bright enough. This will allow the premise owner to save on electricity bills and overheads as lesser energy is used.
The term Sensing Distance refers to the 2 points between the sensor and the maximum outreach that the sensor can scan. Hence, it uses a measurement unit of M (meter) and degrees. For instance, the sensing distance of a typical T8 LED Tube is 6-8 meters at 140 degrees. This means that the sensor will automatically scan around its surroundings between 6 to 8 meters and if it finds that the lighting is sufficient, it will then automatically adjust accordingly.
On top of that, the degrees refer to the level of which the sensor will scan. At 140 degrees, the scanning mechanism is not as wide as those that have the capability of scanning up to 360 degrees which will be checking the entire circle of its radius. This means that the more the degrees of the sensing distance is, the more areas the sensor will be able to scan.
Sensing distance is very important for LED tubes especially when they are deployed in areas which are hard to reach and where there is a need to automatically manage the devices.
