Optek Adds 1W Star Series LEDs for Architectural & General Illumination

Providing lighting design engineers with a versatile, integrated solution for high luminous flux LED lighting, TT electronics OPTEK Technology has developed a complete series of 1W single-LED assemblies on metal-core PC boards.

Designated the OVTLZ Optimal I Star Series, the assemblies consist of OPTEK’s Lednium Series 1W LEDs – proven for reliability, 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 heatsink.

“The Optimal I Star Series LEDs provide tremendous design flexibility for lighting engineers,” said Alan Bennett, vice president of sales & 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.”

Because thermal management of an LED’s junction temperature is the most critical design parameter for optimizing LED efficiency, color consistency and longevity, Bennett continued, OPTEK integrated its 1W LEDs with metal core substrates to provide the superior thermal characteristics that solid-state lighting designers require.

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 PC board.

Typical pricing for the Optimal I Star Series ranges from $1.90 to $2.20 in quantities of 10K. Lead time, if stock is not available, is from 8 to 10 weeks.
