XLamp ML-E

Product catalog summary
Product Description: The Cree XLamp® ML-E LED is a reliable and high-performance ½-watt LED suitable for various lighting applications, including LED bulbs and linear lighting. It offers a wide viewing angle, uniform light output, and precise chromaticity binning in a compact package.
Features:
  • Available in white (2600 K to 8300 K CCT) with CRI options of 80, 85, and 90.
  • Color options include royal blue, blue, green, amber, and red.
  • Supports parallel and series Vf configurations.
  • ANSI-compatible sub-bins.
  • Varied maximum drive current based on color and configuration.
  • Viewing angles: 120° for white, 125° for color.
  • Uniform chromaticity and electrically neutral thermal path.
  • Compliant with RoHS, REACh, and UL standards.
Characteristics: Details on thermal resistance, viewing angles, temperature coefficients, ESD withstand voltage, DC forward current, reverse voltage, forward voltage, and LED junction temperature are provided for different configurations and colors.
Flux Characteristics: Tables list base order codes, minimum luminous flux, and calculated flux values for both parallel and series configurations in white and color LEDs, with noted measurement tolerances.
Relative Spectral Power Distribution: Graphs show the spectral power distribution for white and color LEDs across various wavelengths.
Relative Luminous and Radiant Flux vs. Junction Temperature: Graphs illustrate the relationship between luminous flux and junction temperature for different LED colors and configurations.
Electrical Characteristics: Graphs depict the relationship between forward current and forward voltage for both parallel and series configurations in white and color LEDs.
Overview: The document provides technical specifications and guidelines for XLamp® ML-E LEDs, covering luminous flux, thermal design, reflow soldering characteristics, and compliance with standards.
Specifications: Details on relative luminous flux versus current for different LED configurations and colors, with graphs showing forward current versus luminous flux.
Thermal Design: Emphasizes the importance of minimizing thermal resistance between the LED junction and ambient temperature to optimize lamp life and performance, with graphs showing maximum current versus ambient temperature.
Reflow Soldering: Compatible with JEDEC J-STD-020C standards, with recommended soldering profiles for lead-based and lead-free solder.
