Led Bulbs Parts & Modules

LED bulb parts refer to the various components that constitute a light-emitting diode (LED) bulb. These components work in harmony to produce light efficiently and contribute to the overall functionality and performance of the bulb. Understanding the key LED bulb parts is essential for both manufacturers and consumers: LED Chip: The core of an LED bulb, the chip is a semiconductor device that emits light when an electric current passes through it. The choice of LED chip greatly influences the bulb's brightness, color, and energy efficiency. Heat Sink: LEDs emit light but also generate heat. A heat sink is essential to dissipate this heat and prevent the LED from overheating, ensuring optimal performance and longevity. Driver: The LED driver regulates the electrical current flowing through the bulb, providing a consistent and appropriate power supply. It also converts alternating current (AC) to direct current (DC), which is necessary for LED operation. PCB (Printed Circuit Board): The PCB serves as the platform for mounting the LED chips and other electronic components. It provides electrical connections and structural support. Optics/Lenses: These components control the light's direction and distribution. They can focus or disperse the light, enhancing the bulb's efficiency and usefulness in various applications. Base/Socket: The base of the LED bulb, often designed to fit standard light sockets, provides electrical connections and mechanical support. Common bases include Edison screw bases (E26/E27) and bayonet bases. Diffuser: Some LED bulbs come with diffusers to scatter light more evenly, reducing glare and creating a softer illumination. Enclosure: The outer casing or enclosure protects the internal components and helps shape the light output. It also determines the bulb's form factor, such as A19, PAR30, or BR30. Connectors and Wiring: These elements facilitate the electrical connections between different components, ensuring proper functionality. Capacitors and Resistors: These electronic components play a role in regulating voltage and current within the LED bulb.
