1. Product Overview & General Information:

️· Product: This document is a datasheet for a Cree LED lamp, likely a standard, through-hole type LED.
️· Purpose: The document provides detailed specifications, characteristics, and mechanical dimensions for the LED, designed to inform engineers and buyers.
️· Compliance: The LED is RoHS compliant, meaning it adheres to regulations restricting the use of certain hazardous substances.
️· Safety Warning: Users are cautioned not to stare directly at the LED's light, as it can damage the eye.

2. Electrical and Optical Characteristics:

️· Luminous Intensity: The LED's brightness is specified in terms of luminous intensity (measured in millicandelas or mcd).
️· Forward Voltage (Vf): The voltage required to operate the LED (typically in the 2.0 - 3.5V range).
️· Peak Wavelength: The dominant wavelength of the emitted light (determines the color).
️· Viewing Angle: The angle at which the light intensity falls to a specific percentage of the maximum intensity (usually 50%).
️· Capacitance: A capacitance value is provided, though its significance isn't explicitly stated in relation to LED function.
️· Bins: LEDs are sorted into performance bins based on color, voltage, and brightness ranges. This allows for consistent quality.

3. Mechanical Dimensions:

️· Detailed drawings are provided showing the physical size and shape of the LED, including lead dimensions and epoxy dimensions.
️· Important notes regarding an epoxy meniscus and a burr around the epoxy are provided – these are manufacturing characteristics to be aware of.
️· All dimensions are provided in mm, with a tolerance of ±0.25mm.

4. Kit Number System & Ordering Information:

️· Kit Number Structure: Cree LED kits are ordered with a specific code format that includes bin designations for color, voltage, and brightness. This allows customers to request LEDs meeting particular performance characteristics. Details on the breakdown of the code are *not* given, but it's clear that the kit code defines the performance bin.
️· Packaging: The LEDs are packaged in cardboard boxes with anti-electrostatic bags for protection. Tubes holding 60 LEDs are used.
️· "Cree LED Lamp Packaging Standard": This separate document covers more details on shipping and packaging options.

5. Other Important Points:

️· RoHS Compliance: The LED meets EU RoHS directives regarding hazardous substances.
️· Statistical Data: Performance data provided are based on statistical figures and may not reflect the exact parameters of individual LEDs.
️· Disclaimer: Cree reserves the right to change specifications without prior notice.
️· Vision Advisory Claim - Caution to users to avoid staring at the light
