A LED tap light typically consists of several internal and external components that work together to facilitate its operation. Here's a breakdown of the important parts and their connections:
External Parts:
- Casing/Housing: The outer shell that protects the internal components. It may include a lens or cover to diffuse the light.
- Switch/Button: Usually located on the top or side of the light, it allows the user to turn the light on or off by tapping or pressing.
- LED Light Source: The visible part of the light that emits illumination when powered on. This is often visible through the casing.
- Mounting Mechanism: Such as adhesive pads or a hanger, allowing it to be placed on different surfaces.
Internal Parts:
- Circuit Board: Houses the electrical components, including resistors, capacitors, and sometimes a microcontroller. It connects the switch, LED, and power source.
- LED Driver: A component that regulates power to the LED lights. Ensures they operate safely and efficiently.
- Battery Compartment: Where batteries are housed. Often designed for easy access to change batteries.
- Wiring: Connects the various internal components, such as the battery to the circuit board, and the circuit board to the LED lights.
Connections:
- Switch/Button to Circuit Board: The switch sends a signal to the circuit board to complete the circuit when pressed, turning the LED on or off.
- Circuit Board to LED Lights: The circuit board powers the LED light when activated. The driver ensures appropriate voltage and current levels are supplied.
- Circuit Board to Battery: The battery supplies power to the circuit board. A connection on the circuit board allows for direct power from the battery.
- Wiring Connections: Internal wiring connects the battery to the circuit board and from the circuit board to the LED, ensuring power flows through the light.
Understanding these connections helps in the operation, repair, or modification of LED tap lights.
