LED Engin`s 365nm Emitter Breaks Barriers
The firm's III-nitride based UV LED Gen 2 emitters are claimed to deliver class-leading irradiance in demanding curing applications
LED Engin has launched a 365nm UV LED Gen 2 emitter that delivers up to 1000mW flux output at 2.8W power - claimed to be the highest radiant flux available in the market from a single die package.
The 365nm Gen 2 LZ1-00UV00 emitter produces its irradiance from a compact 4.4mm x 4.4mm footprint, one of the industry's smallest high power UV LED packages. It has a narrow beam angle of 70° that results in more flux in the beam and maximum power density (W/cm2) on target, at least four times higher than its closest competitor.
Due to its small size and high irradiance, the robust emitter offers unparalleled flux density for system developers of fast curing inks, adhesives and coatings. What's more, medical, sterilisation, currency verification, forensic and contamination inspection applications benefit from system efficiencies and cost savings driven by smaller emitters and optics.
The Gen 2 emitter, based on LED Engin's proprietary LuxiGen platform, delivers a combination of low thermal resistance (4.2°C/W) and an improved thermal derating, producing 80 percent relative flux at 100°C case temperature. This enables it to be driven at high drive currents (nominal 700mA) and high junction temperatures (maximum 130°C). The result is sustained maximum flux performance for high temperature applications that allows system designers to employ a smaller heat sink with passive cooling.
President and CEO of LED Engin, David Tahmassebi, comments, "We are proud to have made such a pioneering breakthrough in UV LED technology. Our latest high flux density emitter will deliver new capabilities to UV curing applications, particularly in areas where it is vital to produce and maintain maximum levels of performance. Those customers that have been waiting for dramatic progress in flux density will be very pleased with what LED Engin can offer."
The 365nm UV LED Gen 2 emitter (Part number: LZ1-00UV00) is available now from LED Engin and its distributors.
