It wasn’t too long ago when the world was craving for cheaper, faster to fabricate, better energy efficacy for light source. There was also increasing pining & hope for versatility in color controls, affordable effects & pyrotechnics. Not to mention, lifespan & endurance too.
The wish-list above was considered wishful thinking in the early 1980s. As we progressed in the 1990s, some of the mentioned were considered an engineering feat. At the turn of the millennium, solutions sprang like a fountain; along with it were myriads of algorithms/ permutations for applications. The likes of LED in form of indicative lighting, became widely used for signs, hazard signals, traffic lights, tail brake lights etc. festive lighting too became more excitable, more could be achieved with little more than the conventional budget.
The potential didn’t stop just there, there was also LED for illumination. More effort invested into wafer architecture to boost the luminance in LED chips, such that they are able to produce light many folds brighter than before. And we soon see them quickly inducted into application for projectors, vehicular headlights, floodlights, strode lights & plenty more.
Today, painting environments with light, color coordination for emotive effects, knows no boundaries. In due time, we will realize a very different experience in the retail & hospitality industries.
