Under low current, the temperature rise of LED flood light 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 will deteriorate. In particular, the temperature rise of the 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 uniformly in all directions from a specific point. It is the best analogy to light bulbs and candles. 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 a distance in the scene.
These floodlights can project and blend the darkness on the model. Due to the large range of floodlights, the illumination effect of floodlights is very easy to predict, and there are many auxiliary uses of this kind of light. For example, if the floodlight is placed close to the surface of the object, it will be on the surface of the object. It produces a bright light.
