Under low current, the temperature rise of the LED floodlight is not obvious. If the ambient temperature is high, the main wavelength of the LED floodlight will be red-shifted, the brightness will decrease, and the uniformity and consistency of the light will be deteriorated. In particular, the temperature rise of the dot matrix and the large display screen has a more significant influence on the reliability and stability of the LED floodlight. So thermal design is critical.
Floodlights illuminate objects uniformly from a specific point in all directions, and it is best to use analog lights and candles. Floodlights can be placed anywhere in the scene. For example, it can be placed outside the scope of the camera or inside the object. It is common to use many different colors of floodlights in the scene. These floodlights can project darkness and blend on the model. Because the floodlights have a large illumination range, the floodlights are very easy to predict, and there are many auxiliary uses for 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. Produces bright light on the top.
