What is Light Source
A light source is a device or fixture that emits visible or near-visible radiant energy for the purpose of illumination. It is an essential component in lighting systems, providing artificial light in various settings. Light sources can be categorized into different types, including lamps, bulbs, and LEDs.
Lamps, which are commonly used as light sources, come in various forms such as incandescent, fluorescent, and high-intensity discharge (HID) lamps. These lamps utilize different technologies to produce light, with each type offering unique characteristics in terms of brightness, color temperature, and energy efficiency.

Another type of light source is the LED (light-emitting diode), which has gained popularity in recent years due to its energy efficiency and long lifespan. LEDs are semiconductor devices that emit light when an electric current passes through them. They are available in a wide range of colors and can be used for general illumination as well as specialty applications.
