The solar flood light includes a lamp body, a front cover and a rear shell. A buffer shield is arranged on the surrounding edges of the front cover in an inwardly inclined depression. The lamp body is installed at the center of the buffer shield, and the front cover is along the lamp body. There are heat dissipation through holes at equal intervals around the lamp body, and the back of the lamp body protrudes and extends outward with a rear shell, and a protective cover is installed above the rear shell through a rotating shaft; The column controls the opening angle of the protective cover; the interior of the rear shell is provided with a cooling column, the open end of the cooling column is provided with a regulating plate, and a push-pull regulating plate is embedded in the back plate of the rear shell, and the opening and closing of the cooling column is controlled by the regulating plate .

Solar flood light is a point light source that can illuminate evenly in all directions. Its illumination range can be adjusted arbitrarily, and it appears as a regular octahedron icon in the scene. At present, floodlights are widely used in photography, billboard lighting, stage lighting, and outdoor billboard lighting accounts for a large proportion. In the prior art, some LED lights replace the floodlights of traditional bulbs, so as to achieve the characteristics of lower power consumption and higher brightness. Billboard, can not use the LED floodlight lighting, energy saving is poor.

In addition, the current floodlights on the market will generate a certain amount of heat during use, but they have a short charge-discharge cycle life, and the temperature has a relatively large influence on the capacity, which in turn has a greater impact on the service life of the battery or the lamp body. It is vulnerable to damage, difficult to maintain, and not suitable for widespread use. In addition, its protection performance is poor, resulting in the reliability of LED lighting cannot be guaranteed. Therefore, how to develop a new type of solar flood light to improve the reliability of use has important practical significance.
