What is the goal the input of a light bulb?

The goal of the input of a light bulb is to convert electrical energy into light energy. This process typically involves passing electric current through a filament or gas in the bulb, which generates heat and produces light. The efficiency of this conversion can vary depending on the type of light bulb, such as incandescent, LED, or fluorescent. Ultimately, the aim is to provide illumination for various spaces and activities.
