LED floodlights are mainly used for architectural decorative lighting, as well as to outline the outline of large buildings! Because LED has the characteristics of energy saving, high luminous efficiency, rich color and long life, it is widely used. A good LED flood light must be driven by high-quality and high-power output efficiency, high-efficiency LED light source and high-efficiency heat sink, the perfect combination of the three components, no matter how good the drive is, if it does not match the light source, it will also produce inconvenience. To achieve the best luminous efficiency, the drive and the light source generate heat, which will lose a lot of energy and electrical energy.

As we all know, the heat dissipation conditions of the LED flood light determine the life of the lamp. No matter how good the driving power and light source are, the heat dissipation is not good. Normal use.

It is not easy to understand the rotational symmetry of several classifications of the led floodlight manufacturer's floodlights, but it is easy to understand if we look at the pictures. The rotationally symmetrical floodlight adopts a rotationally symmetrical reflector, which is installed along the axis of the reflector according to the symmetry axis of the light source with rotationally symmetrical light distribution.

The obvious feature of this type of floodlight is that the curve of equal light intensity is concentric, which is not suitable for single lamp lighting. If a single lamp illuminates the illuminated surface, an elliptical light spot will be obtained; however, when multiple lamps are illuminated, the light spots will be superimposed on each other, which can produce a satisfactory lighting effect. For example, hundreds of rotationally symmetrical floodlights are commonly used in stadiums, which are installed on high towers around the stadium to obtain high illumination and high uniformity lighting effects.

The equal-intensity curve of two symmetrical flat-shaped led floodlights has two symmetrical planes. Most led floodlights use symmetrical cylindrical reflectors, and the linear light source is mounted along the cylindrical axis.
