What is BS EN 4706 - LED luminaires about ?
BS EN 4706 is a European standard that defines selection ranks for LED Luminaires, and LEDs including OLEDs for use in aircraft lighting. The size of these ranks is defined using grades.
BS EN 4706 is valid for photopic light levels only.
Who is BS EN 4706 - LED luminaires for ?
BS EN 4706 on LED luminaires is applicable for:
- Aerospace avionic electrical and fibre optic technology
- Manufacturers of LED luminaires
- Aerospace and defence industries
- Designers of LED luminaire
- Aircrafts manufacturers
- Design engineers for aeroplanes and aircrafts
Why should you use BS EN 4706 - LED luminaires ?
LED luminaires are lighting units consisting of LED-based light-emitting elements and a matched driver together with parts to distribute light, to position and protect the light-emitting elements, and to connect the unit to a branch circuit.
The chromaticity coordinates and brightness of LEDs of the same type have variations caused by the manufacturing process; this applies to white LEDs and coloured (monochrome) LEDs. Therefore, LEDs have to be selected by the manufacturer into “Colour ranks”. Also, the brightness of LEDs has certain variations, therefore the LEDs are also selected into “Brightness ranks”. Hence as a manufacturer, you can use BS EN 4706 for selecting ranks for LED Luminaires.
The step width of these ranking systems depends on the manufacturer and the LED type. For certain applications, e.g., inside an aircraft cabin, a high-quality light is demanded, so a manufacturer-independent standardization is desirable.
Thus, the purpose of BS EN 4706 is to provide a simple classification system to enable the end-user to define lighting colour accuracy.
