One kind of lighting that illuminates a wide area in no particular direction is floodlighting. Its main purpose is to use floodlight fixtures to cover a large area and achieve uniform light diffusion.
Lighting that is installed to illuminate the entire space without taking into account location-specific requirements is referred to as general lighting. As seen in public offices, conference rooms, and classrooms, general lighting is characterized by large spaces, numerous lights, and uniform illumination.
The placement, light direction, and installation requirements of floodlighting are different from those of conventional general lighting.
Floodlighting serves a variety of purposes.
One is for safety or ongoing work at night, such as in parking lots or freight yards;
Another option is to highlight statues, signs, or make buildings more visible at night.
A floodlight is a type of point light that provides uniform illumination in all directions.
Its illumination range is adjustable, and it appears as a standard octahedral icon in the scene.
Floodlights are one of the most widely used light sources in rendering; a standard floodlight is used to illuminate the entire scene.
Multiple floodlights can be used in a scene. To achieve better results, the light bulb used for shooting is placed inside a large reflector umbrella, which can be used as a high-brightness diffused light source. While essential for indoor lighting, it can also be considered one of the best light sources for ordinary amateur indoor photography.
Difference between floodlights and spotlights:
Floodlight: A floodlight is a point light source that can evenly illuminate in all directions, uniformly shining light on an object from a specific point in all directions. Its illumination range can be adjusted arbitrarily. Floodlights are the most widely used light source in rendering; a standard floodlight is used to illuminate the entire scene. Multiple floodlights can be used in a scene to produce better effects. Floodlights are almost never specifically defined as a surface-illuminating light source.
Spotlight: A spotlight is a luminaire that makes the illuminance on a specified surface higher than the surrounding environment. It can usually be aimed in any direction and has a structure unaffected by weather conditions. It is mainly used for large-area work sites, building outlines, stadiums, overpasses, monuments, parks, and flower beds. Therefore, almost all large-area outdoor lighting fixtures can be considered spotlights. Floodlights emit beams of varying angles, ranging from 0° to 180°, with those having particularly narrow beams being called searchlights.
