A new substrate technology is claimed to offer significant benefits over conventional polymer-based insulated metal substrates.
Substrates help LEDs burn brighter for longer
Anotherm substrate technology is ideal for LED display applications in gaming and vending machines, outdoor signage and display, emergency vehicle lighting, and architectural and general lighting.
"Our Anotherm substrates are being populated with LEDs and used as replacements for incandescent and fluorescent lighting in a variety of applications, including highway signs, bridges and road lighting", said Tom Morris, Applications Engineering Manager for IRC's Advanced Film Division.
"The Anotherm technology efficiently conducts heat away from the LEDs, increasing their lifespan and light output".
"This is particularly beneficial for applications like highway signage, which often require the use of highway crew and an aerial 'bucket' truck, making replacement an expensive chore".
The Anotherm substrate material enables design engineers to mount visible LEDs and other components directly to it, so there is no need for attached heatsinks, mounting hardware and other associated costs, Morris continued.
Additional applications for the Anotherm substrates include gaming and vending machines, outdoor signage and displays, emergency vehicle lighting, and architectural and general lighting.
The assemblies are constructed using IRC's Anotherm technology, a thermally-conductive aluminium alloy substrate insulated by a thermally conductive, chemically grown, anodised dielectric layer, with solderable screen printed conductors applied to the anodised layer.
The Anotherm substrates feature an insulation system consisting of a thin layer of anodised aluminium oxide that is chemically grown on the aluminium core, producing a dielectric layer approximately 35um thick, which provides an inorganic insulation that is not affected by temperature or chemical exposure.
This rugged construction gives Anotherm technology the ability to operate in extreme temperatures - up to 175C.
Maximum operating voltage is 250V AC, and thermal impedance is characterised at 0.02C/W.
IRC's Anotherm substrates are available RoHS compliant.
