Surface-Mount LEDs Generate Narrow Light Beam

The QuasarBrite narrow-beam LEDs produce a tight beam of high-intensity red, green, or blue light from a surface-mount (SMT) package. Compared to traditional SMT LEDs, these narrow beam LEDs reduce beam angle by 93%, making them well suited for medical device, security, sensor, and visible lighting applications that require concentrated, high-intensity light. The LED is mounted upside down and shines directly into an internal parabolic reflector providing high-intensity brightness in a narrow beam of light without the need for external optics. As a result, the QuasarBrite narrow-beam LEDs can save a good deal of cost and real estate when compared to traditional SMT LEDs that rely on external optics to achieve a tight beam of light. The internal parabolic reflector also collimates the light into a beam, allowing high-intensity light to be produced by a standard LED with standard energy consumption of 75 mW or less. These LEDs provide an intensity up to 100 cd at a view angle of ?6 degrees. The RoHs-compliant QuasarBrite LEDs are available in three sizes: 4mm (provides beam angle of 12 to 22 degrees), 6mm (provides beam angles of 14 to 24 degrees), and 8mm (provides beam angle of 14 to 18 degrees). Samples of these devices are available from stock, with custom and standard production quantities in 8-10 weeks. Pricing is dependent on quantity ordered, and is approximately $1.70 to $7.20 per unit in production quantities. LUMEX, Palatine, IL. (800) 278-5666.
