INTRODUCTION

This application note details the design of a 25-watt equivalent

retail track light using Cree’s XLamp

CXA1512 LED. The

CXA1512 is optimized to simplify designs and lower system

cost and can enable system-level performance of 800 to over

1600 lumens. The XLamp CXA1512 LED delivers high lumen

output and high efcacy in a single, easy-to-use package that

eliminates the need for reow soldering.

The XLamp CXA1512 LED highlighted in this reference design

is optimized to enable applications that traditionally use

halogen, ceramic metal halide (CMH) and compact uorescent

lamp (CFL) technology. The goal of the design is to enable a

retail track light with a narrow beam, based on a single XLamp

CXA1512 LED, delivering performance equivalent to a 25-watt

CMH lamp.
