Decoding the LUMILEDS 2835 Datasheet
The LUMILEDS 2835 Datasheet serves as the definitive reference for anyone working with these LEDs. It provides essential details about the LED’s capabilities, limitations, and operating conditions. Understanding the datasheet ensures the LED is used within its specified parameters, preventing premature failure and maximizing its lifespan and efficiency. The datasheet contains a wealth of information including:
- Forward Voltage (Vf) characteristics at different currents.
- Luminous Flux (lm) output for various drive currents and temperatures.
- Color characteristics (CCT and CRI).
- Thermal resistance (Rth) values.
- Maximum ratings for current, voltage, and temperature.
Datasheets are invaluable tools across many lighting applications. For example, in general lighting, designers refer to the datasheet to select LEDs with the desired brightness and color rendering index (CRI) for indoor and outdoor luminaires. In automotive lighting, engineers use the datasheet to understand the LED’s thermal performance and ensure reliable operation in harsh environments. Furthermore, those working on horticultural lighting systems consult the datasheet to choose LEDs with specific wavelengths that promote plant growth. Datasheets also serve as the basis for quality control and validation, enabling manufacturers to verify the performance of LEDs after assembly.
The specific contents of a LUMILEDS 2835 Datasheet typically include a detailed breakdown of the LED’s performance under various operating conditions. To accurately interpret the data, one needs to understand the terminology used and the significance of each parameter. For instance, the datasheet specifies the forward voltage (Vf) at a given forward current (If). This information is crucial for designing the LED driver circuit. Similarly, the luminous flux indicates the amount of light emitted by the LED and is a critical parameter for achieving the desired brightness in a lighting application. Lastly, note that the “2835” refers to the LED package’s dimensions (2.8mm x 3.5mm).
