Low current, LED floodlight light temperature rise is not obvious. If the ambient temperature is high, the main wavelength of LED floodlight will be red shift, brightness will drop, luminous uniformity, consistency of variation. In particular, the temperature rise of dot matrix and large display screen has more significant effect on the reliability and stability of LED floodlight. So the heat dissipation design is very important.
Floodlight is the best way to simulate light bulbs and candles by illuminating them evenly from a particular point to each direction. Floodlight can be placed anywhere in the scene. For example, it can be placed outside the camera range, or inside the object. It is common to use many different colors of floodlight in a remote range. These floodlights can project shadows and mix them on the model. Because of the large range of floodlight illumination, the effect of floodlight is very easy to predict, and there are many auxiliary uses for such lighting, for example, to place the floodlight near the surface of the object, it will produce bright light on the surface of the object.
