Samples are now available of PerkinElmer's new ACULED® VHL TM (very high lumen) ultra high power LEDs. ACULED VHL offers outstanding brightness with a luminous flux of up to 325 lumens, improved luminous efficacy and all the benefits of the newly enhanced ACULED platform including its compact, easy-to-assemble design and long lifetime.
ACULED VHL is offered via Pacer International in monochromatic (UV, Blue, Green, Yellow, Red, IR), and also in a RGBY (red-green-blue-yellow) version with a higher colour rendering index than the basic RGGB combination. These new devices offer a step change improvement in thermal management. The thermal resistance of the ACULED VHL package can be as low as 4.5 K/W, depending on the chip configuration. ACULED solutions are based on PerkinElmer Elcos' superior multi chip-on-board (COB) technology. In addition, each chip features a separate anode and cathode, enabling the chips to be driven individually, thus increasing flexibility around electrical layout. For higher volume applications, there is even a Design-Your-Own version of ACULED giving customers total flexibility to design their own four-chip LED configuration to suit their specific lighting application needs.
