Under small 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 luminescence will deteriorate. In particular, the temperature rise of dot matrix and large display has a more significant impact on the reliability and stability of LED floodlights. So the heat dissipation design is very important.

LED 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's range or inside an object. It is common to use many different colored floodlights in the scene at a distance. These floodlights can project and blend the darkness on the model. Because the floodlight has a relatively large illumination range, the illumination effect of the floodlight 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.
