Lumex, the American manufacturer, introduced the QuasarBrite narrow-beam SMT LED, which provides high-intensity red, green and blue dense beams. Compared to traditional SMT LEDs, QuasarBrite narrow-beam SMT LEDs reduce beam angle by 93% for medical applications such as dense light and high-intensity light, safety equipment, sensors and other lighting applications.
Lumex Engineering Director Jeff Oliveros said that while traditional SMT LEDs have many advantages, they do not provide a narrow beam without the use of external light sources. Traditional SMT LEDs offer beam ranges from 45 to 85 degrees. However, the QuasarBrite narrow-beam SMT LEDs provide a range of light beams between 6 and 10 degrees, reducing beam angles by up to 93%.
The QuasarBrite narrow-beam SMT LED can be mounted upside down directly into a built-in parabolic reflector to produce high-intensity light in a narrow beam without the need for an external source. As a result, QuasarBrite narrow-beam SMT LEDs can save 50% in cost and 50% on substrates compared to traditional SMT LEDs that use dense light beams with external sources.
The built-in parabolic reflector also calibrates the astigmatism into a beam of light, thus allowing ordinary LEDs with a standard energy consumption of 75 mW or less to emit high-intensity light. A typical SMT may produce 1 cd of brightness at a 45 degree viewing angle; a QuasarBrite narrow beam SMT LED can produce light intensities up to 100 cd from a 6 degree viewing angle.
QuasarBrite narrow-beam SMT LEDs certified by RoHs Green include 4 mm (providing a beam angle of 12 to 22 degrees), 6 mm (a beam angle of 14 to 24 degrees) and 8 mm (a beam angle of 14 to 18 degrees) Different sizes. 
Even in extreme weather conditions, the all metal extruded aluminum alloy enclosure with cast aluminium top and bottom plates are fully dust and weatherproof
