OctoLED surface-mount devices

July 31, 2008
Lumex announces a new line of surface-mount devices that represent the first commercial technology to combine the convenience of surface-mount technology (SMT) with the features and capabilities of through-hole, leaded T-5mm epoxy lens LEDs. The patent-pending OctoLEDs™ devices are the result of a design breakthrough at a time when most assemblies are moving toward SMT technology.  “The OctoLED design is a direct replacement to standard 5mm through-hole LEDs,” explains Jeff Oliveros, Director of Engineering at Lumex. “OctoLEDs are ideal for any situation where there is a need to transition from through-hole to SMT technology, without sacrificing the light emission features of epoxy lenses.” The new OctoLEDs deliver brightness levels of up to 7,000mcd (dependent on color) – a market first from any conventional SMT LED driven by the common If of 20mA.Lumex OctoLEDs (Series Number SML-H1505xxx-TR) can be used anywhere the convenience of surface mounting is required, with the high brightness, color and viewing angle choices of standard T-5mm LEDs.  Such applications include front panel, PCB multi-LED and industrial control or fault indicators. Additional applications include circuit fault and large scale muti-color light bars, large display edge illumination, dot matrix moving sign displays and other dot matrix arrays where each LED needs to be individually-addressable.OctoLEDs have an off-the-board height of 11mm (0.43 inches) and occupy a circuit board footprint which is 6mm x 6mm (0.24 inches x 0.24 inches). They are available on standard 24mm tape for automatic insertion.  Lumex OctoLEDs are available in the full range of colors including red, yellow, green, blue, or white.  Bi-color as well as RGB versions are also offered.  The LEDs are available with a variety of lens finishes, opening the door to different viewing angle options (angle will vary dependent upon lens type).  The new units can withstand soldering temperatures of up to 10 seconds at 255º C.  A gradual temperature rise of 2º per second reaching 150º C is recommended.  Lumex OctoLEDs are RoHS compliant.
