aerospace & defence introduction aerospace & defence with nearly 40 years experience providing innovative photonics solutions, marl is acknowledged as one of the pioneers of the led industry. during this time the marl brand has become synonymous with a global reputation for quality, backed up with first class technical support and supply logistics. customers can choose logic and status indicators from thousands of variants; marl have now supplied more than 100 million pcb leds! some of the world’s first electronic light bulbs were made by marl in the 1980s and today these are still enhancing the operational performance and reliability of the host equipment in countless defence and aerospace applications. our manufacturing division offers a wide range of high performance ingress protected panel indicator lamps which are ideal for applications demanding a combination of high performance, high reliability and outstanding value for money. because of the in-house capability for rapid proto-typing, environmental test and scope of supply, (small, medium and high volume), we also welcome enquiries for custom projects for applications requiring indication or illumination. at marl, being able to meet specification is taken for granted, what we offer stretches the barriers in order to meet and exceed client need and expectation. the highly experienced marl team includes optosource, (the component and accessory distribution division), which provides customers with access to some of the best emerging light engine technology in the world, which enables our clients to stay ahead of their competition. other elements of added value service include stock deliveries for components; short lead times for products made to order and managed obsolescence programmes against competitors who can’t stay the distance. customers keep on returning to marl because they like the breadth and depth of design and manufacturing expertise and our flexible approach! leds will probably become the light sources of choice for man machine status indicator interfaces and most applications requiring illumination for most of the 21st century; estimates suggest that 19% of current global energy is required for artificial light and that leds might potentially reduce energy requirement by 50% by 2020! enquiries for ruggedised energy saving products and systems are particularly welcome. for example; ‘cool white’ led lighting, (4000k to 5000k), works well for security and perimeter lighting for direct viewing, or integration with cctv. marl brings unrivalled knowledge of led technology to the science and art of lighting. all activities are supported by appropriate international accreditation, quality and environmental standards; BS EN ISO 9001:2008 www.leds.co.uk for more information please visit: “please contact me if you require advice on selecting the correct led indicator or lighting solution for your application!” Graham Round aerospace & defence sales manager vice president of sales marlopto e: [email protected] more contact details on back page please contact us on: t: +44 (0)1229 582 430 w: www.leds.co.uk contents light emitting diodes -
