CXA1520 LED

PRODUCT DESCRIPTION

The XLamp

CXA1520 LED is Cree’s

rst High Density (HD) LED array,

featuring a 9-mm optical source and

enabling lighting manufacturers

to create a new generation of

products that delivers the same

intensity and light quality as 39-W

ceramic metal halide (CMH) at up

to 50 percent lower power. The

new HD class of CXA arrays provide

unrivaled lumen density that can

reduce system cost for the next

generation of LED spotlights.

The CX Family LED Design Guide

provides basic information on the

requirements to use the CXA1520

LED successfully in luminaire

designs.

XLamp ® CXA1520 LED Relative Spectral Power Distribution - White, Hot Binned, Baby Relative Spectral Power Distribution The following graph is the result of a series of pulsed measurements at 500 mA and TJ = 85 °C.
PAGE 7
XLamp ® CXA1520 LED Relative Luminous Flux The relative luminous flux values provided below are the ratio of: • Measurements of CXA1520 at steady-state operation at the given conditions, divided by • Flux measured during binning, which is a pulsed measurement at 500 mA at TJ = 85 °C. For example, at steady-state operation of Tc = 105 °C, IF = 700 mA, the relative luminous flux ratio is 120% in the chart below. A CXA1520 LED that measures 2100 lm during binning will deliver 2520 lm (2100 * 1.

XLamp ® CXA1520 LED Thermal Design The CXA family of LED arrays can include over a hundred different LED die inside one package, and thus over a hundred different junction temperatures (TJ). Cree has intentionally removed junction-temperature-based operating limits and replaced the commonplace maximum TJ calculations with maximum ratings based on forward current (IF) and case temperature (Tc). No additional calculations are required to ensure the CXA LED is being operated within its designed limits.

XLamp ® CXA1520 LED Notes Measurements The luminous flux, radiant power, chromaticity and CRI measurements in this document are binning specifications only and solely represent product measurements as of the date of shipment. These measurements will change over time based on a number of factors that are not within Cree’s control and are not intended or provided as operational specifications for the products.
