The NICHIA 219B LED is a popular choice for flashlight enthusiasts, DIY lighting projects, and various other applications that demand high-quality light output. Understanding the NICHIA 219B Datasheet is crucial for anyone wanting to properly utilize this versatile component. The datasheet provides all the technical specifications and performance characteristics needed to design reliable and efficient lighting systems around the LED.
Understanding the NICHIA 219B Datasheet
The NICHIA 219B Datasheet serves as the comprehensive guide to understanding everything about this specific LED model. It contains a wealth of information, from basic electrical characteristics like forward voltage and current to more detailed performance metrics such as luminous flux, color rendering index (CRI), and correlated color temperature (CCT). It also outlines the absolute maximum ratings, which are the limits beyond which the LED can be damaged. Ultimately, the datasheet allows designers and hobbyists to make informed decisions about how to use the LED safely and effectively.
A typical NICHIA 219B datasheet will likely contain the following kinds of data (this is not exhaustive):
- Absolute Maximum Ratings: These are the extreme limits that the LED can withstand without being damaged. Exceeding these ratings can lead to permanent failure.
- Electrical Characteristics: This section covers the forward voltage, forward current, and reverse current of the LED. These parameters are essential for designing the driver circuit.
- Optical Characteristics: This includes information about the luminous flux (brightness), correlated color temperature (CCT), color rendering index (CRI), and viewing angle.
- Thermal Characteristics: Details about the LED’s thermal resistance, which is crucial for managing heat dissipation.
The information in the datasheet is used in numerous ways. For example, an engineer designing a flashlight needs the forward voltage and current information to select the appropriate battery and driver circuit. They’ll use the thermal resistance data to design a heat sink that will prevent the LED from overheating. And they’ll use the optical characteristics data to understand the color and brightness of the light emitted by the LED, and this knowledge is invaluable for creating products that meet specific performance requirements. A small example of what a table in the datasheet may look like:
| Parameter | Symbol | Value | Unit |
|---|---|---|---|
| Forward Voltage | Vf | 3.2 | V |
| Forward Current | If | 350 | mA |
