What is a floodlight？

A floodlight is a point light source that can uniformly illuminate in all directions, and its illumination range can be adjusted arbitrarily, appearing as a regular octahedron in the scene. Floodlights are the most widely used light source in rendering, and standard floodlights are used to illuminate the entire scene. Multiple floodlights can be applied in the scene to produce better effects.

Floodlights are the most widely used type of light source in renderings, and multiple floodlights can be used to coordinate and create better effects in a scene. It is to uniformly illuminate an object from a specific point in all directions, and it is the best analogy to light bulbs and candles. Floodlights can be placed anywhere in the scene.

Due to the large illumination range of floodlights, the illumination effect of floodlights is very easy to predict, and this type of light has many auxiliary uses. For example, placing floodlights near the surface of an object will produce bright light on the surface of the object.

Characteristics of floodlights:

Under low current, the temperature rise of LED floodlights is not significant. If the ambient temperature is high, the main wavelength of LED floodlights will shift red, the brightness will decrease, and the uniformity and consistency of light emission will deteriorate. The temperature rise of dot matrix and large display screens has a more significant impact on the reliability and stability of LED floodlights. So heat dissipation design is crucial.

A floodlight illuminates an object uniformly from a specific point in all directions, and it is best compared to a light bulb and a candle. Floodlights can be placed anywhere in the scene. For example, it can be placed outside the camera range or inside an object. It is common to use many different colored floodlights at long distances in the scene.

Due to the large illumination range of floodlights, the illumination effect of floodlights is very easy to predict, and this type of light has many auxiliary uses.
