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. to order to order please contact us on: t: +44 (0)1229 582 430 f: +44 (0)1229 585 155 e: [email protected] w: www.leds.co.uk © marl international limited technical documentation has been designed by marl international limited for the intention of providing information, which must not be copied or released to a third party without prior written consent from marl international limited. the information provided does not constitute part of any order or contract and should not be regarded as a representation relating to either products or service. no responsibility can be assumed for inaccuracies or printing errors. marl international limited reserve the right to alter without notice the specification or any conditions of supply for product or service. marl international limited - dsn 669 - version 2013-10-07-173533 BS EN ISO 9001:2008 approved manufacturer page 4 of 4
