How to Read LED Datasheets: the Parts Optical Engineers Care About for Illumination/Lighting Design
Simple breakdown of LED Datasheet terms important for LED lighting design.
To schedule a free consultation to discuss 🗣️👩💻👨💻🧑💻 what we can do in a contract to optimize YOUR non-imaging 💡 optical system,
• color: warm white, cool white, neutral white
• color temperature aka CCT aka K aka Kelvin
• flux values aka lumens
• Why don’t you get lumens at 85° for all vendors?
• test current and forward voltage
• efficiency in lumens/Watt
• cautions about sorting LEDs by efficiency
• CRI (color rendering index) 🌈
• metamerism 🧡❤️♥️/♥️♥️♥️
• more on CRI 🌈and when it’s important for machine vision
• maximum current ⚡️rating and how NOT to use it
•Viewing Angle – is it what you assumed it is⁉️⁉️ Probably not! Plus —
•Beam Angle 📐
•forward voltage ⚡️
•maximum temperature 🤒
•Flux and chromaticity 🌈 bins, and
•Do white LEDs emit UV light? 🤔
•Do you know LEDs warm up 🔥when they’re on?
•Do you know what happens 🙀when they warm up?
•Why size matters 🐘
•Most important data for optical engineers that’s not on the datasheet! 😲 — ray files !
