Lumileds launches 1700lm single-die LED
LED maker Lumileds of San Jose, CA, USA has unveilled its highest-flux-density LED. Packaged in a compact 4.0mm x 4.0mm footprint, LUXEON V can be driven harder than other LEDs in its class, it is reckoned, due to new die and packaging technologies. Luminous flux is more than 1700lm at a correlated color temperature (CCT) of 5700K and a color rendering index (CRI) of 70 (4.8A) – 50% higher output than competing LEDs, the firm claims.
“LUXEON V enables fixture designs that were previously unattainable for stadium and area lighting, torch and other portables because of the unique combination of high efficacy at high drive current with extremely low thermal resistance and optimized radiation pattern,” says Kathleen Hartnett, senior director, product marketing.
LUXEON V LEDs leverage Lumileds’ next-generation patterned sapphire substrate (PSS) chip-scale packaging (CSP) technology, enabling high efficacy at high drive currents, higher maximum drive current and higher lm/mm2. The nominal drive current is 1.4A and the LEDs may be driven at up to 4.8A – 60% higher than competing emitters, it is reckoned. With the industry’s lowest thermal resistance of 0.8K/W, designers can use smaller heat sinks for more compact fixtures.
Offered in a range of CCTs including 3000-6500K, LUXEON V LEDs feature a standard 3-stripe footprint for ease of design and assembly.
