LED maker Lumileds of San Jose, CA, USA has launched the LUXEON HR30 LED, a mid-power device that withstands harsh chemical environments (including chlorine and sulfur) and is designed with robust packaging and industry-best materials to operate for over 100,000 hours continuously. The LED addresses the great need for dependable lighting that will operate in hazardous environments (such as chemical plants, power generation facilities and natatoriums) and be able to withstand extremes of temperature and operating current.
"The LUXEON HR30 is the only LED in its class to provide a service life in the 100,000 hour range [at 105°C] while withstanding corrosive elements like sulfur and chlorine," says Matthew Everett, senior product director for LUXEON Mid Power Products. The LED's chemical resistance is partially attributed to its gold-plated leadframe and its optimized materials package. The LUXEON HR30 has demonstrated strong performance in chemical resistance tests such as IEC68-2-43 (15ppm): ΔLOP < 10%, Δu'v' < 0.006 after 21 days.
"Engineering for chemical resistance is all about selecting the best materials and then testing those materials under harsh conditions," says Everett. "We have leveraged our expertise in materials science and lumen maintenance to produce the industry's most robust mid-power LED," he claims.
The LUXEON HR30 produces 125 lumens at a luminous efficacy of 134lm/W when driven at 150mA current at a color temperature of 4000K and a color rendering index (CRI) of 70. The LED is available at color temperatures of 4000K, 5000K and 5700K at 70 CRI and 2700K, 3000K, 4000K and 5700K at 80 CRI.
