Oxman Lighting offers a new approach to thermal management with its DL1 LED downlight
The Oxman Lighting DL1 replaces the heavy, inefficient finned heatsink that is traditionally used to cool LED downlights with a thin, low weight Total Surface Heat Exchanger. This thermal management positively influences material input, size, weight and performance.
Oxman Lighting has produced a powerful, more efficient, durable and compact downlight. At less than 30mm deep, the ultra slim DL1 produces 1,200lm of 92CRI light from a fitting that weighs just over 100g.
Oxman Lighting founder Philip Oechsle says the new downlight brings a new approach to cooling that has been verified through independent tests.
“It’s a COB, LED downlight without compromise; this technology can be used in numerous applications, from downlights through to high-bays and will see huge savings in raw materials for the lighting industry,” he says.
The traditional finned heatsink comes with flaws like storing heat and unwanted temperature gradient from the base of the led to the tip of the cooling fin. The Total Surface Heat Exchanger eliminates these shortcomings by transferring heat from the base of the LED to the ambient cooling air in the shortest and most efficient way possible.
The LED chip is directly attached to the thin, light weight heat exchanger, which, on the reverse side, creates the high temperature difference that drives the convective cooling process so effectively. Additional cooling is achieved by conduction, where the heat exchanger makes direct contact with the mounting surface.
Oxman Lighting considers its DL1 downlight a quantum leap in LED downlight performance. The DL1 is available for purchase via the Oxman website (www.oxmanlighting.com); further distribution channels are currently being sought.
