The Concept and Characteristic of Flood Light

Time: 2018-12-01 14:27:52

LED floodlight is a point light source which can illuminate evenly in all directions. Its illumination range can be adjusted arbitrarily, and it can be shown as a regular octahedron in the scene. Floodlight is one of the most widely used light sources in rendering. Standard floodlights are used to illuminate the whole scene. Multiple floodlights can be used in the scene to produce better results.

Floodlight is one of the most widely used light sources in effect maps. In scenes, many floodlights can coordinate to produce better results. It's best to use it to analogize light bulbs and candles by illuminating objects evenly from a particular point in all directions. The floodlights can be placed anywhere in the scene.

For example, it can be placed outside the scope of a camera or inside an object. It is common to use many different colours of floodlights over long distances in scenes. These floodlights can cast shadows and mix them with models. Owing to the large illumination range of the floodlights, the illumination effect of the floodlights is very easy to predict, and there are many auxiliary uses for this kind of lights. For example, if the floodlights are placed near the surface of the object, the bright light will be produced on the surface of the object.

It should be noted that floodlights can not be built too much, otherwise the effect will appear flat and rigid. Therefore, we should pay more attention to the influence of lighting parameters and layout on the light sensitivity of the whole scene, accumulate more experience, and master the skill of lighting collocation.

Characteristics of floodlights:

At low current, the temperature rise of LED floodlights is not obvious. If the ambient temperature is high, the main wavelength of the LED floodlights will be red-shifted, the brightness will decrease, and the uniformity and consistency of the luminescence will become worse. Especially, the temperature rise of lattice and large display screen has more significant influence on the reliability and stability of LED floodlights. So heat dissipation design is very important.
