Lumex develops narrow beam SMT LEDs to reduce beam angle by 93%
US LED manufacturer Lumex has announced the launch of QuasarBrite narrow-beam SMT LEDs to provide high-intensity red, green or blue dense beams. Compared to traditional SMT LEDs, this narrow-beam SMT LED reduces beam angle by 93%, making it ideal for medical devices, safety equipment, sensors, and lighting that require dense, high-intensity light.
“Despite the many advantages of traditional SMT LEDs, these LEDs do not provide a narrow beam without the use of external light sources,†explains Jeff Oliveros, engineering director at Lumex. “With QuasarBrite narrow beam SMT LEDs, this can be effectively addressed. The traditional SMT LEDs offer beam ranges from 45 to 85 degrees. However, the QuasarBrite narrow beam SMT LEDs provide a range of light between 6 and 10 degrees, reducing beam angles by up to 93%."
With the QuasarBrite narrow-beam SMT LED, the LED can be mounted upside down directly into the built-in parabolic reflector and 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 draw dense beams with external sources. The need to use an external light source greatly simplifies the production process and saves additional costs.
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. From a 45-degree perspective, a typical SMT may produce 1 cd of brightness. From a 6-degree perspective, the QuasarBrite narrow-beam SMT LED produces light levels up to 100 cd. The QuasarBrite narrow beam SMT LED certified by RoHs Green includes 4 mm (providing a beam angle of 12 to 22 degrees), 6 mm (a beam angle of 14 to 24 degrees) and 8 mm (availability of 14 to 18 degrees) Beam angle) and other different sizes.
