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.

Voltage, Current and Temperature

The forward voltage / current value of an LED is dependent

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.

Marl should be contacted if the device is to be operated

outside the temperature range specified. Marl accept no

liability for any product that is operated outside the stated

voltage or temperature range.
