NOTES

Intensities (lv) and colour shades of white (X-Y co-ordinates) may vary between LEDs within a batch. Additional LED Colours, Voltage Options and Reverse Polarity options available for

semi-custom projects. Please contact our Sales Team. All LED components are supplied in anti-static packaging.

* For operating temperature derating graphs, please refer to sheet 2.

DESIGN CONSIDERATIONS

Single-Chip LEDs

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.

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.

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.

Electro-Static Discharge (ESD)

Flat-topping does not apply to devices using surface-

mounted device (SMD) LEDs.

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

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.

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

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.
