What is the difference between LED floodlights and led floodlights

1. The difference between the cast Bai lamp and the floodlight lies in the angle of the light, but now many people are confused because there is no standard to distinguish between them. The beam of the projection lamp is relatively uniform, that is, the light source is more concentrated on buildings or landscape objects, but now it can also be made into astigmatism. Secondly, the illumination range of floodlight is relatively large2. You can adjust it at will. In fact, the floodlight is a category of the floodlights. Here you have a clear understanding! There is no unified standard for quality. Basically, LED projection lamps are made according to the general shape parameters, or the appearance is adjusted, so that they can choose more heat dissipation problems. The portable floodlight optical characteristics of LED lead to glare problems. A good light transmission lamp shade is needed to form a surface light source to a certain extent. At present, the use of sanding or adding some materials, with the development of these years, the light transmission performance has been further improved. SMD LED is mostly driven by low voltage and uses aluminum substrate for heat dissipation. The current LED projection lamps are not specially used for lighting, some are used to produce good projection effect.
