DESIGN CONSIDERATIONS

Single-Chip LEDs

All devices feature water clear high intensity LEDs as standard.

Product Evaluation

Filament Replacement LEDs have been specifically designed to meet the primary objective of providing improved reliability. As this product range

is suitable for both new-build and retro-fit, (sometimes in very old systems), a wide range of illuminated lamp holders can be encountered. Due to

subjectivity, evaluation of the LED

Power Derating

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, Marl should be contacted if the device is to be operated at a temperature significantly higher than 25°C.

Marl accept no liability for any product that is operated higher than the stated voltage.

Electro-static Discharge (ESD)

Build up of electrostatic 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. We recommend all users of LED based products follow the guidelines of BS 100015.

Note:

All luminous intensity figures refer to the unmodified discrete LED.
