For anyone involved in LED lighting design, specifying components, or understanding the technical intricacies of illumination, the Cree Xte Datasheet is an indispensable resource. This document serves as the ultimate guide to the Cree XLamp XT-E LED, providing all the critical information needed to harness its impressive capabilities.
Understanding the Cree Xte Datasheet: Your Blueprint for Brilliance
At its core, the Cree Xte Datasheet is a comprehensive technical document published by Cree, Inc. (now Infineon Technologies) detailing the specifications, performance characteristics, and application guidelines for their XLamp XT-E LED series. This isn't just a simple list of numbers; it's a meticulously crafted manual that empowers engineers, designers, and hobbyists alike. It outlines everything from the basic electrical and optical properties to thermal management considerations and recommended operating conditions. Understanding and utilizing the information within the Cree Xte Datasheet is paramount for achieving optimal performance, reliability, and longevity in any lighting project.
The applications for the XT-E LED, and by extension the information in its datasheet, are incredibly diverse. You'll find these LEDs powering everything from high-output industrial lighting and architectural fixtures to automotive headlights and even specialized grow lights. The datasheet helps designers select the right bin for their specific needs, ensuring they get the desired brightness, color temperature, and efficiency. It provides crucial data such as:
- Luminous Flux (lumens)
- Color Temperature (Kelvin)
- Color Rendering Index (CRI)
- Forward Voltage (Vf)
- Forward Current (If)
- Thermal Resistance (Rth)
Moreover, the datasheet includes performance curves that illustrate how the LED's output and efficiency vary with changes in current and temperature. This data is vital for designing effective thermal management systems, as LEDs generate heat during operation. Without proper heat dissipation, the LED's performance can degrade, and its lifespan can be significantly reduced. The Cree Xte Datasheet often includes tables and graphs that detail recommended operating currents and corresponding thermal requirements, helping users avoid common pitfalls.
For instance, a typical section in the datasheet might present a table like this:
| Forward Current (mA) | Typical Forward Voltage (V) | Typical Luminous Flux (lm) | Typical Efficacy (lm/W) |
|---|---|---|---|
| 350 | 3.0 | 130 | 100 |
| 700 | 3.2 | 240 | 95 |
This kind of information, presented in an organized manner, allows for direct comparison and informed decision-making. It also includes critical safety and handling guidelines, ensuring that users can work with the LEDs without compromising their integrity or their own safety. The Cree Xte Datasheet is not just a technical document; it's a comprehensive guide that unlocks the full potential of the XT-E LED.
To truly master the capabilities of the Cree XLamp XT-E LED, there is no substitute for delving into the official Cree Xte Datasheet. This document is your primary source for accurate and detailed technical specifications. Make sure to consult it before embarking on your next lighting design project.
