1. The difference between a projector and a floodlight lies in the angle of light projection, but now many people are confused because there is no standard to distinguish between them. The beam of a projector is relatively uniform, that is, the light source is more concentrated on buildings or landscape objects, but now it can also be made astigmatism. Secondly, the floodlight has a larger illumination range.
2. You can adjust it arbitrarily. When it comes to floodlights, they are actually a category of projectors. Here you may have a clearer understanding. There is no uniform standard for quality. Basically, LED projectors are made on the basis of roughly shape parameters, or adjust their appearance, so that they can choose more heat dissipation problems. The optical characteristics of LED with reasonable heat dissipation structure lead to glare problems. A good light transmission lampshade is needed to form a surface light source to a certain extent. Nowadays, grinding or adding some materials are often used. With the development of these years, the transmittance has been further improved. Most of the patch LEDs are driven by low voltage and heat dissipation is achieved by using aluminium substrates. The LED projectors used nowadays are not specially used for lighting, some are used to produce good projection effect.
