filament replacement leds

209 series

design considerations

Single-Chip LEDs

All devices feature water clear high intensity LEDs as standard. In devices where discrete LEDs are used, the single

chip LED devices have been modified by the removal of the domed portion of the encapsulation (flat-topped) to provide

even illumination of switches and annunciators. Non flat topped versions are also available.

Flat-topping does not apply to devices using surface-mounted device (SMD) LEDs.

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 push

button switches and lamp holders can be encountered. Due to subjectivity, evaluation of the LED type is recommended,

(samples of all standard models are available). Care should be taken to correctly simulate operating ambient light conditions to

ensure that the correct device has been selected to maximise viewing characteristics such as viewing angle, colour

compatibility and on/ off contrast ratio.

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, 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.
