Anatomy of an LED Lightbulb & Infographic

 

The anatomy of an LED light bulb is worth knowing. It will help to understand how the light operates as well as what makes it so efficient. Let’s take a closer look at anatomy of an LED light bulb.

The Base

The base is usually made of a lightweight metal, such as aluminum, which screws into the socket of the fixture.

Thermal pottants: Act as a heat control to help absorb the minimal heat produced to keep the bulb from getting hot.

Encapsulates: Thermally conducive for power components.

The Bulb

While many people think of the bulb as its own entity in the anatomy of an LED light bulb, it is actually broken up into several parts.

Housing: The lower end of the bulb connecting the lens to the base. This area holds any heat produced and may be the warmest part of the bulb, but still not as warm as an incandescent thanks to the overall cool operation of LEDs.

Lens: An optic lens placed on the top of the bulb to help with even light dissipation due to brightness. It helps with creating an even light distribution and is usually made of plastic instead of the glass of other bulb types.

Internal Parts

Within the housing and the lens, there are a few integral components which are essential to the operation of an LED light bulb.

Circuit: A small electronic component which acts as the brain of the bulb by signaling for the bulb to turn off or on, works as the communion center for dimmers, and powers the bulb through the lamp socket.

Heat Sink: A small metal board which holds the LED chips and works to direct heat away from the chip during the process of producing light.

LED Chips: A small chip which creates the illumination. They are usually yellow and are connected to the metal of the circuit.
