The Lumina Dot pendant light began as an idea to create a ‘disc of light’. An assembly of two parallel discs connected by a metal stem, its simple form belies an inherent complexity that pushes the boundaries of existing technology.
The smaller disc – made of machined aluminium – contains a ring of LEDs that bounce the light off the larger spun aluminium reflector disc. Given the high heat produced by LED lamps, its housing would normally need to accommodate a heat-sink to absorb and dissipate the heat, which can be quite bulky. To preserve the minimal form of the lamp, the design uses an innovative heat tube that connects the two discs. This tube contains a fluid that turns to vapour as it absorbs the heat, transferring it efficiently to the heat sink in the reflector. Two separate lenses cover the LEDs – a ring shaped lens that focuses the light accurately onto the entire reflector, and a holographic filter lens that gives it a uniform illumination, avoiding shadows from the stem. The result is a minimal pendant light that gives the appearance of a floating disc of light.
