High-efficacy LEDs aimed at providing uniform, homogeneous light distribution

Mouser is now stocking the DURIS E 2835 LEDs from OSRAM Opto Semiconductors. Aimed at providing uniform, homogeneous light distribution, the family are mid-power LEDs that combine good efficacy and a wide beam angle in an industry-standard 2835 (2.8mm × 3.5mm) footprint. The LEDs are ideal for retrofits and general indoor lighting designs in a variety of consumer and industrial applications. The LEDs are available in two output versions of 0.2W (3V) and 1 (9V) to give designers choice of performance and cost. The 0.2W LEDs feature higher luminous efficacy, as well as lower power dissipation and lower luminous flux. The 1W LEDs feature higher luminous flux, lower luminous efficacy, and higher power dissipation. Both versions are housed in a compact surface-mount package and offer a wide 120-degree beam angle at 50% luminous intensity. The LEDs offer illumination color options of warm white, cool white, or neutral white (2700K to 6500K) with a minimum Color Rendering Index (CRI) of 80. The LEDs can withstand up to 2kV of ESD voltage according to ANSI/ESDA/JEDEC JS-001 (HBM, Class 2). The 0.2W LEDs are ideal for linear and area lighting fixtures and T8 tubes, and the 1W LEDs are suited for lamps and consumer downlights and fixtures. The 0.2W LEDs feature typical luminous efficacy of 150lm/W at 5000K and luminous flux of 27lm at 5000K with forward voltage and current of 3V and 60mA. By contrast, the 1W LEDs have lower luminous efficacy of 118lm/W at 3000K and higher typical luminous flux of 113lm at 3000K with a typical operating voltage of 9.6V and forward current of 100mA. Both versions offer an operating temperature range of minus 40C to 85C and a junction temperature of 120C.
