LED LIGHTS FOR METERS & RADIOS 3MM BLUE (LED3B)
LED3B are small, bright blue LED lights commonly used to illuminate meters, dials, and other components in radios, audio equipment, and various electronic devices. They offer several advantages over traditional incandescent bulbs:
- Energy efficiency: LEDs consume significantly less power than incandescent bulbs, leading to longer battery life and reduced heat generation.
- Long lifespan: LEDs have a much longer lifespan than incandescent bulbs, reducing the need for frequent replacements.
- Durability: LEDs are more resistant to shock and vibration, making them suitable for use in harsh environments.
- Brightness: LEDs can produce bright, consistent light without the need for warm-up time.
- Color accuracy: LEDs offer a wide range of colors, including pure blue, making them ideal for applications where color accuracy is important.
Applications:
- Radio meters: Illuminate dials, needles, and other indicators.
- Audio equipment: Backlight displays, buttons, and knobs.
- Electronic devices: Provide ambient lighting for panels and controls.
- Automotive applications: Illuminate gauges, switches, and other interior components.
Typical Specifications:
- Size: 3mm diameter
- Color: Blue
- Viewing angle: 120 degrees
- Operating voltage: 2-3.2 volts
- Forward current: 20 milliamps (mA)
- Luminous intensity: Typically measured in milli-candelas (mcd)
Note: The specific specifications may vary depending on the manufacturer and intended application. It’s essential to select LEDs that are compatible with your device’s power supply and operating conditions.
Additional Considerations:
- Resistors: LEDs typically require a current-limiting resistor to protect them from damage. The resistor value depends on the LED’s forward voltage and the desired current.
- Polarity: LEDs have a polarity and must be connected correctly. Incorrect polarity can cause damage or prevent the LED from lighting up.
- Lens options: Some LED3B lights may come with different lens options (e.g., clear, diffused, frosted) to control the light distribution and intensity.
