| Lednium series 3D LED array package  Combining high brightness LEDs with a three-dimensional packaging technology, Optek Lednium Series, the 10W package offers a full 120° viewing angle for its array of amber, blue, green, red, or white LEDs. Optek's Lednium Series devices achieve an output of up to 330 lumens with nine 1W LEDs mounted in an anodized aluminum package just 1.3 inches square, with a board mounted profile of less than .5 inch. Conventionally-packaged LED arrays with comparable light output often require as many as 12 1W LEDs in configurations up to 8 inches in diameter, which typically consume more power.The wide viewing angle and increased brightness are critical features for lighting design engineers as they begin to incorporate solid state light sources into applications such as automotive interior and exterior lighting, indoor and outdoor electronic signage and displays, as well as architectural lighting and general lighting applications. The Optek Lednium Series LED assemblies also provide different parallel-serial connections that enable the operation of 3, 6 or all 9 of the mounted LEDs, enabling design engineers to vary the light output and power consumption. OPTEK's Lednium Series devices are available in amber; blue; green; red; and white. All colors feature a full 120° viewing angle in water clear lenses. In development are other visible, as well as UV and IR wavelengths and package configurations. DC forward current is 1.05A, with peak pulsed forward current of 3A. Typical forward voltage characteristics range from 6.3V to 9.25V, and reverse voltage for all devices is 15V. Maximum allowable junction temperature is 130°C, and the operating temperature range for the device is -50°C to +80°C. write your comments about the article :: © 2006 Construction News :: home page |
