Part of the XcelLED series, the EHP-AX08/P01 (1-W) and EHP-AX08/P03 (3-W) families of LEDs deliver high luminosity, long operating life, and system efficiency in a broad range of designs. Applications that benefit from the LEDs include backlighting (CFFL replacement in LCD TVs and screens), automotive lighting (interior and exterior signaling), and architectural, aerospace, and emergency lighting. The emitters feature a silicon lens and a high luminous flux of up to 90 lm/W. Sized in an industry-standard 8 × 8 × 5.7-mm SOP package, these LEDs are designed to handle higher reflow soldering temperatures and, unlike other packaging methods, their silicon encapsulation prevents accelerated degradation. EHP-AX08 devices optimize heat control by providing a low thermal resistance of 15°C/W, alleviating a primary concern in LED applications. In addition to increasing brightness, EHP-AX08 LEDs save power since their high-lumens output allows the LEDs to be driven at lower currents. Many different configurations and device options are offered for design flexibility.
