This document is more than just a collection of numbers; it's the key to unlocking the optimal performance and application of this renowned LED.
The Heart of the Matter: What the Cree XM-L2 Datasheet Reveals
The Cree XM-L2 Datasheet is a comprehensive technical document provided by Cree Inc. (now part of Wolfspeed) that details the electrical, thermal, and optical characteristics of their XM-L2 Light Emitting Diode. It's the official blueprint that tells you everything you need to know about how this LED behaves under various conditions. Think of it as the user manual for the LED, packed with critical specifications that guide design and implementation. Engineers, product developers, and even advanced DIY enthusiasts rely on this datasheet to ensure their lighting projects are efficient, reliable, and meet their performance goals. Without it, making informed decisions about power, thermal management, and optical design would be a guessing game.
The information contained within the Cree XM-L2 Datasheet is vital for several key reasons:
- Performance Metrics: It outlines crucial data such as luminous flux (brightness), luminous efficacy (how efficiently it converts electricity to light), color rendering index (CRI, how accurately it shows colors), and forward voltage.
- Electrical Characteristics: You'll find maximum and recommended drive currents, voltage drops at different currents, and ESD (Electrostatic Discharge) sensitivity, which is essential for preventing damage during handling.
- Thermal Management: This is paramount for high-power LEDs. The datasheet provides junction temperature limits, thermal resistance values, and recommended operating temperature ranges. Proper thermal management is key to the LED's lifespan and consistent performance.
- Optical Specifications: This includes beam angle information, chromaticity coordinates (describing the color of the light), and spectral power distribution.
These specifications are typically presented in a structured format, often including:
| Parameter | Typical Value | Units |
|---|---|---|
| Luminous Flux | 1070 | lumens (at 700mA) |
| Forward Voltage | 2.9 | Volts (at 700mA) |
| Thermal Resistance | 2.1 | °C/W |
Understanding and applying the data from the Cree XM-L2 Datasheet directly impacts the success of your project. For instance, knowing the thermal resistance allows you to calculate the necessary heatsink size to keep the LED within its safe operating temperature. Similarly, understanding the luminous flux at different drive currents helps you select the right power supply and optimize brightness while managing heat.
