The Pilot Lamp Green is a small indicator light designed to emit a green glow, commonly used to signal the operational status of a device or circuit. It is a simple yet essential component in various electronic systems, providing a clear visual indication of power, activity, or fault conditions. Its compact size and low power consumption make it ideal for use in control panels, machinery, appliances, and other electronic devices.
Below are the key technical details for the Pilot Lamp Green:
Parameter | Value |
---|---|
Operating Voltage | 12V DC (common) or 24V DC |
Current Consumption | 10-20 mA |
Light Color | Green |
Mounting Type | Panel Mount |
Lamp Type | LED or Neon (depending on model) |
Housing Material | Plastic or Metal |
Diameter | 8mm, 10mm, or 12mm (varies by model) |
Lifespan | 30,000 - 50,000 hours |
The Pilot Lamp Green typically has two terminals for connection:
Pin | Description |
---|---|
Positive (+) | Connect to the positive terminal of the power supply. |
Negative (-) | Connect to the negative terminal (ground). |
The Pilot Lamp Green can be used as an indicator in Arduino projects. Below is an example of how to connect and control it:
// Example code to control a Pilot Lamp Green with an Arduino UNO
// The lamp is connected to digital pin 13 through a 220-ohm resistor
const int lampPin = 13; // Define the pin connected to the lamp
void setup() {
pinMode(lampPin, OUTPUT); // Set the lamp pin as an output
}
void loop() {
digitalWrite(lampPin, HIGH); // Turn the lamp ON
delay(1000); // Wait for 1 second
digitalWrite(lampPin, LOW); // Turn the lamp OFF
delay(1000); // Wait for 1 second
}

Q: Can I use the Pilot Lamp Green with an AC power supply?
A: Some models are designed for AC operation, but most require DC. Check the specifications of your lamp.
Q: What resistor value should I use for a 12V power supply?
A: For an LED lamp with a forward voltage of 2V and current of 20mA, use a 500-ohm resistor. Calculate using ( R = \frac{12V - 2V}{0.02A} ).
Q: Can I use the lamp outdoors?
A: Yes, if the lamp has a weatherproof housing. Verify the IP rating for outdoor use.
