Thermal Design: Utilize the low thermal resistance by providing an adequate thermal path on the PCB, such as using thermal vias and connecting to a sufficient copper area or heatsink.

Current Driving: Use a constant current driver to ensure stable light output and prevent thermal runaway. Refer to the derating curve (Fig 8) when operating at high ambient temperatures.

Optical Design: The 120-degree viewing angle provides wide illumination. Secondary optics (lenses, reflectors) can be used to shape the beam pattern for specific applications.

10. Tambayoyin da Ake Yawan Yi (Bisa Ma'auni na Fasaha)

Q: What is the maximum current I can drive this LED at?
A: The absolute maximum continuous current is 600mA. However, for optimal lifetime and reliability, it is advised to operate at or below the test current of 350mA, especially in high-temperature environments, following the derating curve in Fig 8.

Q: How do I interpret the luminous flux binning?
A: The bin code (AP, AQ, AR, AS) indicates the guaranteed minimum and maximum flux output from the LED at 350mA. For consistent brightness in an array, specify LEDs from the same or adjacent flux bins.

Q: Can I use this LED for a turn signal that must meet specific color regulations?
A: Yes. The dominant wavelength bins (Y7: 585-590nm, Y8: 590-595nm) allow you to select LEDs that fall within the required yellow color specifications for automotive signals. Always verify against the applicable regulatory standard.

11. Ƙira da Amfani da Aikace-aikace na Aiki

Case: Automotive Rear Turn Signal Lamp
A designer is creating a new LED-based rear turn signal cluster. They select this Ceramic 3535 Yellow LED for its proven reliability and color. They design a PCB with a 2oz copper layer and thermal vias under the LED pad to dissipate heat to a metal core or the lamp housing. They choose LEDs from the Y8 wavelength bin and AS flux bin for a bright, consistent amber color. A constant-current driver is designed to supply 300mA per LED (derated from 350mA for extra margin in the hot rear lamp environment). The wide 120-degree angle reduces the number of LEDs needed for the required field of view. The reflow profile is carefully controlled to the datasheet specifications to ensure solder joint integrity.
