Key Parameters in the Piranha LED Datasheet

Several key parameters in the Piranha LED datasheet are essential for evaluating the LED's performance and suitability for a particular application:

Forward Voltage and Forward Current

The forward voltage (Vf) is the voltage drop across the LED when a forward current (If) flows through it. These values are critical for determining the appropriate driver circuit and ensuring that the LED operates within its specified range.

Luminous Intensity and Luminous Efficacy

Luminous intensity (Iv) is the total amount of light emitted by the LED, measured in candelas (cd). Luminous efficacy (η) is the ratio of the luminous intensity to the electrical power consumed, measured in lumens per watt (lm/W). These parameters help in comparing the efficiency and brightness of different LEDs.

Color Temperature and Color Rendering Index

Color temperature (CCT) is the measure of the color of light emitted by the LED, expressed in Kelvin (K). The color rendering index (CRI) quantifies the ability of the light to accurately represent colors. These parameters are crucial for applications where color accuracy is important, such as in retail or architectural lighting.

Thermal Resistance and Maximum Operating Temperature

Thermal resistance (θja) is a measure of how well the LED dissipates heat. The maximum operating temperature is the highest temperature at which the LED can safely operate without degrading its performance. These parameters are important for ensuring the LED's longevity and preventing overheating.
