EMC stands for Electro Magnetic Compatibility. This means the product’s ability to functionin in its environment without causing or being subject to electrical or electromagnetic interference.
An EU directive refers to prevailing European Norms for electrical interference from a product (EN 50081) and a product’s resistance to electrical interference (EN 50082).
For light fittings we have our own product norms that supersede these. These are EN 61547 for immunity and EN 55015 for radiated interference.
Since the introduction of the EMC directive Glamox has built up a comprehensive laboratory where we can carry out the relevant tests ourselves. As a result we have built up a sound expertise in the field.
An important criterion for the approval of light fittings is the temperature of vital components. We have a laboratory for conducting standard heat measurement tests for most conditions. We have our own hot box for simulating environments from -40°C to +100°C. We have draught proof rooms to conduct standard tests at 25°C.
The importance of heat measurement is becoming ever greater as electronics become more common in luminaires. As a rule of thumb, the lifetime of an electronic component will double for every ten degrees reduction in ambient temperature. It is therefore important to place an HF reactor in a cool place. «Ta» stands for Temperature Ambient – or ambient temperature. If the luminaire is not specially labelled it is designed for normal Ta = 25°C. Glamox has products designed for use in environments from - 40°C to + 55°C.
