These new high-performance LEDs allow designers to offer more efficient system cost reductions in high-performance, high-brightness applications designed to meet the new DLC (DesignLights Consortium) 4.0 Premium requirements.
The Cree XLamp MHB-B LEDs, available from Mouser Electronics, incorporate key elements of Cree's SC5 Technology™ Platform, which combines high light output, high efficiency, and high reliability to enable high-brightness designs not possible with a mid-power LED. These LEDs deliver up to 931 lumens at 85 degrees Celsius and 13 percent more lumens per watt (LPW) than the MHB-E LED in the same 5mm x 5mm package, allowing lighting manufacturers to quickly increase the performance of existing MHB designs without any additional investment.
The MHB-B LED enables designs that utilize lighter and smaller heat sinks than designs based on a medium-power LED. For example, a reference design built with MHB-B LEDs delivers 24,000 lumens and over 130 LPW of system efficacy, with 44 percent less weight and 36 percent less diameter than comparable designs based on a medium-power LED. Built on Cree's high-power ceramic technology, MHB-B LEDs have readily available LM-80 data and offer reported L90 life projections of 60,000 hours at 105 degrees Celsius.
Cree XLamp MHB-B LEDs are available from Mouser Electronics in color temperatures ranging from 2700K to 5000K and color rendering indices (CRI) of 70, 80, and 90.
