How Do LED Globe Lights Work

Understanding how LED globe lights work involves delving into the underlying principles of LED (Light Emitting Diode) technology. They utilise semiconductor devices to produce light efficiently. Here's a step-by-step explanation of the mechanism behind these lights:

LED Components

At the heart of LED technology are semiconductor diodes, tiny devices made from materials such as gallium arsenide or gallium phosphide. These diodes have two semiconductor layers – one with an excess of electrons (N-type) and the other with a deficit of electrons, creating "holes" (P-type).


When a voltage is applied across the diode, an electric current flows. As electrons move from the N-type layer to the P-type layer, they recombine with the holes.

This process is known as electroluminescence, and it releases energy in the form of photons (light).

Colour Determination

The specific semiconductor materials used in the diode determine the colour of the emitted light. Different materials emit photons at different wavelengths, resulting in various colours. For example, a combination of red, green, and blue LEDs can produce white light.

Phosphor Coating (for White Light)

Manufacturers often apply a phosphor coating to the semiconductor material to achieve a white light output in LED globe lights. This phosphor coating helps in the conversion of the monochromatic light emitted by the LED into a broader spectrum, creating a more natural and pleasing white light.

LED Driver

These lights operate on low-voltage direct current (DC), but the standard electrical supply in homes and buildings is alternating current (AC). These lights are equipped with an LED driver, which is a power supply unit that converts the incoming AC power to the DC power required for the LEDs to function.

Heat Dissipation

LEDs are sensitive to heat, and excessive heat can impact their performance and lifespan. To address this, they are designed with built-in heat sinks or cooling elements. These components dissipate the heat generated during operation, ensuring that the LEDs remain within their optimal temperature range for consistent and efficient performance.

Optical Components

Circular lights often incorporate optical components, such as lenses or diffusers, to control the direction and distribution of light. These components allow for the creation of specific lighting patterns, directing the emitted light where it is needed and contributing to the overall design and functionality of the light fixture.
