LED modules earmark exceptional thermal performance, color options

Optek Technology offers a complete series of 1W single-LED assemblies on metal-core PCBs. Designated the OVTLZ Optimal I Star Series, the assemblies consist of OPTEK's Lednium Series 1W LEDs, which offers long life and low thermal resistance (<2°C/W)—integrated with a thermally-conductive heat spreader substrate to achieve an overall thermal resistance of 4.9°C/W from LED junction to an additional heat sink.

"The Optimal I Star Series LEDs provide tremendous design flexibility for lighting engineers," said Alan Bennett, VP of sales and marketing for Optek Technology. "Available in a full range of colors, including three colors of white light specifically designed to meet requirements for architectural and general illumination, the assemblies feature a robust, energy-efficient design that can be mounted with thermal epoxy and/or mounting screws."

The Optimal I Star Series LEDs are being specified for architectural and general illumination, interior/exterior automotive lighting, signage and specialty lighting applications.

The Optimal I Star Series LEDs are offered with a viewing angle of 135° in the following emitted colors/luminous flux values: blue (460nm/12lm), cyan (505nm/40lm), green (515nm/60lm), red (625nm45lm), amber (595nm/35lm), cool white (7000K/65lm), daylight white (5800K/60lm), and warm white (3500K/50lm). Typical forward voltage at 350mA ranges from 2.3V to 3.6V, depending on color.

Four soldering pads provide two pads each for anode and cathode connections, as well as locating slots for mounting screws. The assemblies are 0.78 inches (19.8mm) in diameter on a 0.04 inch (1mm) thick PCB.
