Understanding the Technology behind LED Bulbs
The technology behind LED bulbs is founded on the concept of electroluminescence, a process where light is emitted from a material when it is subjected to an electric current or a strong electric field. By applying the right amount of electricity, semiconductors (which make up an LED) recombine with electron holes within the device, releasing energy in the form of photons. This process is called recombination and the color of the light (corresponding to the energy of the photon) is determined by the energy band gap of the semiconductor.
LED bulbs are unique because they do not use a filament or a tube. It emits light when an electrical current passes through a tiny chip, usually encased in a plastic lens. The resulting light is a fast source of bright light that is highly energy-efficient. Essentially, they produce luminous efficacy that is several times better than traditional light sources.

Role of Semiconductors in LED technology
Semiconductors form the fundamental part of LED technology. They are made from the element gallium, which is alloyed with various other elements like arsenic or phosphorus to produce the desired light color. When electricity is applied to the semiconductor material, the electrons in the material become excited and jump from one energy level to another, releasing light in the process. The color of this light refers to the specific energy gap in the semiconductor.
Types of LED Bulbs
There are several different types of LED bulbs available, each designed to meet specific lighting needs. Spotlight LED bulbs, for example, emit a narrow beam of light and are suitable for focused lighting in areas like artwork displays or architectural details. Then you have Globe LED bulbs that spread light in all directions, making them an ideal choice for area lighting or in decorative pendant lights. Candle LED bulbs, on the other hand, offer a more aesthetic appeal and are suitable for chandeliers or other decorative applications where the bulb is visible.
While there are numerous other types of LED bulbs, these three are the most commonly applied in residential settings.
