TECHNICAL INFORMATION Lamp Base Style Series Metric Equivalent (mm) Maximum Power Dissipation (mW) Bayonet Cap T3¼ BA9s 215 10 625 DESIGN CONSIDERATIONS Green dot on base of product indicates centre cont act cathode -ve. Colour dot on sleeve denotes LED colour . Dimensions in mm (Typical) Not to Scale Single-Chip LEDs All devices feature water clear high intensity LEDs as st andard. 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, please contact the sales department for details. 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 st andard 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 comp atibility and on/off contrast ratio. Electro-static Discharge (ESD) Build up of electro-static discharge occurs in many situations involving people moving and handling product s. The range of possible situations is very diverse but voltage levels as high as several thousand volt s 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 product s. Although LEDs were never considered to be st atic sensitive devices, changes in manufacturing technology and materials used to produce higher intensity product s 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 p acking and despatch. We recommend all users of LED based product s 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 volt age/current values, depending upon the ambient temperature. Consequently, a recommendation regarding operating voltages and currents is given in order to address these temperature ef fects. 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 st ated voltage. Note: All luminous intensity figures refer to the unmodified discrete LED.
