7. Tambayoyin da ake yawan yi (FAQ)

Q: What is the main advantage of the EMC package?
A: The EMC package provides enhanced thermal conductivity compared to standard PPA plastic, leading to lower junction temperature, higher maximum drive current capability, and improved long-term reliability and lumen maintenance.

Q: How do I interpret the derating curve (Fig. 8)?
A: The curve shows the maximum continuous current you can safely apply at a given ambient temperature for a specific thermal resistance (Rth j-a) of your system. You must know your system's effective Rth j-a to use the correct curve. Exceeding these limits risks overheating and premature failure.

Q: Can I drive this LED at 240mA continuously?
A: You can only drive it at 240mA if the junction temperature is kept at or below 125°C. In most practical applications, especially at higher ambient temperatures, the current will need to be derated according to Fig. 8 to stay within the Tj limit.

Q: What is the purpose of the color binning?
A: Manufacturing variations cause slight differences in chromaticity between individual LEDs. Binning groups LEDs with very similar color coordinates together. Using LEDs from the same or adjacent bins in a fixture ensures uniform white color appearance without visible color differences (color mismatch).
