Features of floodlights:
Under low current, the temperature rise of LED floodlight is not obvious. If the ambient temperature is high, the dominant wavelength of the LED floodlight will be red-shifted, the brightness will decrease, and the uniformity and consistency of the light emission will become worse. In particular, the temperature rise of dot matrix and large display screens has a more significant impact on the reliability and stability of LED floodlights. So the heat dissipation design is very important.
Floodlights illuminate objects evenly in all directions from a specific point, and it's a perfect analogy to light bulbs and candles. Omnilights 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 floodlights of different colors at a distance in a scene.
These floodlights can cast and blend shadows on the model. Due to the large illumination range of the floodlight, the illumination effect of the floodlight is very easy to predict, and this kind of light has many auxiliary uses. For example, if the floodlight is placed close to the surface of the object, it will be produces bright light.
