Lighting has been a persistent element of modern consumer electronics design since the early 20th century: early radios, vacuums, and ovens glowed with incandescent readouts. Little changed until the LED was introduced in the 1980s into consumer products, which revolutionized the ability of designers to add light both as a functional indication and an aesthetic element. Most lighting applications today are now LED-based, although new technologies such as electro-luminescence (EL) are becoming more widely adopted in select applications. However recent aesthetic developments in lighting as a purely aesthetic element seem to be technology-agnostic. Designers use the right technology for their intended effect, be it linear, graphic, glowing strips, glowing surfaces, or flexible strands woven into fabric. What has certainly declined is the simple hole-in-the-housing treatment where the raw LED shines through. More sophisticated treatments wash the lighting across surfaces, or refract through layers of translucency, or blur the line between form and light. Recently, Apple made the lighting detail disappear altogether by shining an LED through micro-perforated holes in their aluminum housings. Still waiting for those black-light LED’s to come out to light up my Zeppelin poster….
