The datasheet includes several key graphs for design analysis. The Forward Current vs. Relative Intensity curve shows how light output scales with current. The Forward Current vs. Forward Voltage (IV) curve is essential for designing the driving circuitry. The Ambient Temperature vs. Relative Luminous Flux graph illustrates the expected light output drop as the operating temperature increases, highlighting the importance of thermal management. The Ambient Temperature vs. Relative Forward Voltage curve shows the negative temperature coefficient of VF. The Viewing Angle Distribution plot confirms the Lambertian-like emission pattern with a 120-degree half-angle. The Color Spectrum graph displays the spectral power distribution, typical of a phosphor-converted white LED, with a peak in the blue region from the chip and a broad phosphor emission in the yellow/red region.

Typical Application Scenarios: This LED is ideal for indoor lighting fixtures such as downlights, panel lights, and tube lights. It is also suitable for retrofitting older fluorescent or incandescent fixtures with LED technology. In architectural lighting, it can be used for coves, shelves, and accent lighting where warm white tones are preferred.

Design Considerations: 1) Thermal Management: Given a typical thermal resistance of 9°C/W, proper heat sinking is mandatory when operating at or near maximum ratings to prevent premature lumen depreciation and color shift. 2) Current Driving: A constant current driver is recommended to ensure stable light output and color. The driver should be chosen based on the forward voltage bin and the required operating current. 3) Optical Design: The wide 120-degree viewing angle makes it suitable for applications requiring broad illumination without secondary optics, though lenses or reflectors can be used for beam control.

10. Tambayoyin da ake yawan yi (Dangane da Sigogi na Fasaha)

Q: What driver voltage is needed for this LED?
A: The LED requires a driver that can supply the necessary voltage to overcome the forward voltage (VF) of the LED string. With a VF of 56-58V at 25mA, a driver with an output voltage capability above 58V is recommended, accounting for tolerances and temperature effects.

Q: How does temperature affect performance?
A: As shown in the performance curves, luminous flux decreases as ambient/junction temperature increases. The forward voltage also decreases with temperature. Effective thermal management is crucial to maintain stated performance.

Q: What is the meaning of the 5-step MacAdam ellipse?
A: It defines the area on the color chart where LEDs are considered a color match. A 5-step ellipse is a standard for good color consistency in general lighting, meaning the color difference between two LEDs from the same bin is barely perceptible to most observers.

11. Ƙirar Aiki da Misalin Amfani

Case: Designing a retrofit LED tube light. A designer is replacing a traditional T8 fluorescent tube with an LED version. They select the 4000K, Ra80 variant of this LED for a neutral white light suitable for office environments. They plan to connect 20 LEDs in series to achieve the desired length and light output. Using the typical VF of 58V per LED, the total string voltage is approximately 1160V. This necessitates a driver capable of handling this high voltage or suggests a different series-parallel configuration is needed to match available, safe driver voltages. The designer must also design an aluminum PCB or heat sink structure to manage the heat from 20 LEDs dissipating up to 1.45W each, ensuring the junction temperature stays within safe limits to achieve the claimed lifetime.
