Interior signs are designed to capture attention and therefore it comes as no surprise that illuminated signs and signage tend to be more effective than non illuminated signs. We all respond to bright lights and colour after all.
Ways of providing illumination for signage have always mirrored evolving technology. Fluorescent signs were first introduced in 1923 and soon neon signs – neon is the gas used in the fluroescent tube – became the ‘must have’ for every retailer on the High Street.
The next big breakthough came with the advent of electronic solid state devices. The first LEDs (light emitting diode) were produced in the 1960s but it has only been relatively recently that technical developments in brightness and colour availability have made LED illumination the technology of choice for use with signage.

How LED illumination works
Light emitting diodes are just that, semiconductor diodes that emit light. They do so by emitting photons when an electric current is applied across the semiconductor junction. Fortunately they require less power to produce light in this way than say a fluorescent tube does. Different colours are produced either by using different semiconductor materials which emit photons of differing wavelengths or by combining the light from multiple LEDs to produce the required colour.
