design considerations
Electro-Static Discharge (ESD)
Build up of electro-static discharge occurs in many situations involving people moving and handling products. The range of
possible situations is very diverse but voltage levels as high as several thousand volts can and do arise in many individual
situations. When an operator charged up to these levels handles a static sensitive device, there is a very probable likelihood
that the device will be irreversibly damaged. It is essential that precautions are taken at all stages during manufacture and
assembly of these products. Although LEDs were never considered to be static sensitive devices, changes in manufacturing
technology and materials used to produce higher intensity products over a large range of the wavelength spectrum have
changed this. Marl has an approved system of ESD control from goods in, through production and into final packing and
despatch. Marl recommend all users of LED based products follow the guidelines of BS 100015.
Power De-Rating
The forward voltage/ current value of an LED is dependant upon the ambient temperature of the environment in which it is
operated. Therefore, care must be taken to operate the LED at the correct voltage/ current values, depending upon the
ambient temperature. Consequently, a recommendation regarding operating voltages and currents is given in order to address
these temperature effects. This recommendation is termed ‘de-rating’. It is usual for forward voltages and currents to be
specified for ambient temperature of 25°C. However, because the values of these qualities vary with temperature, please refer
to the de-rating graphs for correct operation. Marl accept no liability for any product that is operated higher than the stated
voltage.
