The XLamp XM-LED can be considered as the highest performing, single die solid state LED module which is able to produce lights at ultra bright intensities. Let's learn it's datasheet, specifications.

High Illumination Efficacy

Due to it's ultra bright and high efficiency values, the Xlamp becomes highly suitable for applications such as in automotive headlamps, stadium flood lights, for home lighting, street lighting, practically anywhere which requires high illumination at minimum space and consumption.

To be precise an Xlamp is able to generate 1000 lumen with 100 lumen per watt efficacy.

The main features which makes this breakthrough device exceptionally desirable for lighting applications may be studied with the following data:

How to Drive a Cree Xlamp XM-LED

Since the the performance and life of the Cree Xlamp is inversely proportional to its junction temperature, a high quality current controlled driver becomes a must for operating these ultra bright LEDs. Let's learn a few of the application circuits for safely driving  the proposed LED devices.

Applying In Automotive Headlights.

When used for automotive headlamp applications, the following circuit may be employed:


For Home Lighting

The same circuit may be used  for home lighting applications, the design is given below:

For all applications, the LEDs must be mounted on suitable heatsinks for getting optimal performance.
