QuasarBrite Narrow Beam SMT LEDs by Lumex, Palatine, IL, provide users with a tight beam of high-intensity red, green or blue light.  Compared to traditional SMT LEDs, LEDs allow for a 93% reduction in beam angle, making them suitable for medical device applications such as surgical tools and medical diagnostic equipment indication that require concentrated, high-intensity light.

“SMT LEDs traditionally could not provide a narrow beam of light without the use of external optics,” explains Jeff Oliveros, director of engineering at Lumex. He says traditional SMT LEDs offered a light beam of ±45 to ±85 degrees; QuasarBrite Narrow Beam SMT LEDs provide a light beam of ±6 to ±10 degrees.

QuasarBrite LEDs are mounted upside down and shines directly into an internal parabolic reflector providing high-intensity brightness in a narrow beam of light. Because they don’t require external optics, they can provide a 50% cost savings and 50% real estate savings. No external optics also simplifies manufacturing processes, resulting in additional cost savings.

The internal parabolic reflector collimates the light into a beam, letting high-intensity light be produced by a standard LED with standard energy consumption of 75mW or less. An SMT may have a brightness of 1cd with a view angle of ±45 degrees.  QuasarBrite Narrow Beam SMT LEDs provide an intensity up to 100cd at a view angle of ±6 degrees.

The RoHs compliant QuasarBrite Narrow Beam SMT LEDs are available in the following sizes:
• 4mm (provides beam angle of 12 to 22 degrees)
•  6mm (provides beam angles of 14 to 24 degrees)
•  8mm (provides beam angle of 14 to 18 degrees)
