The piranha LED datasheet is a comprehensive document that provides detailed technical specifications and information about piranha LEDs, which are a type of high-performance, blue-violet light-emitting diode. This article aims to delve into the intricacies of the piranha LED datasheet, exploring its significance in the industry, the technology behind piranha LEDs, and their applications.
Understanding the Piranha LED Datasheet
The piranha LED datasheet is a crucial resource for engineers, designers, and manufacturers working with these advanced LEDs. It contains vital information such as electrical characteristics, optical specifications, thermal data, and mechanical dimensions. This section will provide an overview of what can be expected in a typical piranha LED datasheet.Apiranha LED datasheets typically begin with a product overview, which includes the LED's model number, package type, and color. The color of a piranha LED is usually specified in terms of its dominant wavelength, which can range from 390 nm to 420 nm. This range is particularly important for applications such as UV curing, laser diode pumping, and fluorescence microscopy.
Electrical Characteristics
One of the most critical sections of the piranha LED datasheet is the electrical characteristics. This section provides detailed information about the LED's forward voltage, forward current, and maximum power dissipation. These parameters are essential for determining the LED's operating conditions and ensuring its compatibility with the driving circuit.Forward voltage is the voltage drop across the LED when it is forward biased and conducting current. It is a critical parameter for determining the power supply requirements. The datasheet will specify the typical and maximum forward voltages for the piranha LED, as well as the current-voltage (I-V) characteristics.
Optical Specifications
The optical specifications of a piranha LED datasheet are equally important, as they define the LED's light output and beam characteristics. This section includes the LED's luminous intensity, radiant intensity, and color coordinates.Luminous intensity is a measure of the total amount of light emitted by the LED, and it is usually expressed in milliwatts (mW) or candela (cd). The datasheet will provide the typical and maximum luminous intensities at a specific forward current. Radiant intensity, on the other hand, is a measure of the light emitted in a particular direction and is expressed in milliwatts per steradian (mW/sr).
Color Coordinates
Color coordinates are essential for applications that require precise control over the color of the emitted light. The piranha LED datasheet will typically provide the CIE 1931 color coordinates (x, y) for the LED's dominant wavelength. These coordinates are used to determine the color temperature and chromaticity of the light emitted by the LED.Thermal Data
Thermal management is a critical aspect of LED design, and the piranha LED datasheet will provide information on the LED's thermal resistance and thermal characteristics. This data is crucial for ensuring that the LED operates within its specified temperature range and that it is not subject to overheating.Thermal resistance is a measure of how much a material resists heat flow. The datasheet will specify the junction-to-ambient thermal resistance for the piranha LED, which is important for determining the heat sink requirements. Additionally, the datasheet may include information on the LED's thermal impedance and thermal derating curves.
Mechanical Dimensions
The mechanical dimensions of the piranha LED are important for ensuring proper mounting and thermal dissipation. The datasheet will provide detailed information about the LED's package size, lead pitch, and other mechanical features. This information is crucial for designers and manufacturers when designing the LED's PCB layout and heat sink.Applications of Piranha LEDs
