LEDs Boost Luminosity, Slice Thermal Resistance

Enlarging the XcelLED series high power LEDs are the 1W EHP-AX08/P01 and 3W EHP-AX08/P03. Their emitters feature a silicon lens and the LEDs specify a luminous flux up to 90 lm/W and a typical thermal resistance 15°C/W. Available in industry-standard, 8 mm x 8 mm x 5.7 mm SOPs, they handle higher reflow soldering temperatures and their silicon encapsulation prevents accelerated degradation. Other features include a choice of four lenses, Lambertian, Batwing, Side-emitting, and Focus, eight basic colors including white with at least two versions of each, and a star heat sink for each configuration. Prices range from approximately $1 for standard 1W versions to $2.20 for 3W components in production quantities. EVERLIGHT AMERICAS INC., Carrollton, TX. (972) 490-4008.
