Blue LEDs - Pack of 10:

Blue LEDs (Light Emitting Diodes) emit light in the blue part of the electromagnetic spectrum. These semiconductor devices generate light when an electric current is applied. Here are some key features and considerations regarding blue LEDs:

1. Color Wavelength:
   • Blue LEDs typically emit light in the wavelength range of approximately 450 to 495 nanometers, depending on the specific material used in the LED.
2. Energy Efficiency:
   • LEDs, including blue LEDs, are known for their energy efficiency. They convert a significant portion of electrical energy into visible light, making them widely used in various applications.
3. Applications:
   • Blue LEDs are used in a variety of applications, including indicator lights, display panels, signage, decorative lighting, backlighting for displays (e.g., smartphones, TVs, computer screens), and in combination with phosphors to create white light in LED lighting systems.
4. Forward Voltage:
   • The forward voltage drop across a blue LED typically ranges from 2.7 to 4.0 volts, depending on the specific LED. This voltage is crucial when designing circuits to ensure proper forward biasing of the LED.
5. Intensity:
   • Blue LEDs are available in various intensity levels, usually measured in millicandelas (mcd) or lumens. The choice of intensity depends on the specific application and the desired brightness.
6. Forward Current:
   • The forward current, measured in milliamperes (mA), is the amount of current required for the LED to operate within its specified parameters. It's crucial to adhere to the manufacturer's recommendations to prevent damage to the LED.
7. Lens Type:
   • Blue LEDs may have different lens types, such as diffused or clear. The lens type affects the dispersion of light and the visibility of the LED.
8. Long Lifespan:
   • LEDs, including blue LEDs, have a longer lifespan compared to traditional light sources. They are known for their durability and reliability.
