The floodlight is composed of 3 parts: optical parts, mechanical parts and electrical parts. The optical components are mainly reflectors and shading grids that limit light. The mechanical parts are mainly the housing, the focusing mechanism for fixing and adjusting the position of the light source, the bracket and the base for fixing the lamp, and the parts with angle indication to adjust the beam projection direction of the lamp. For most of the closed floodlights, the mechanical parts also have protective glass and various sealing rings. According to the needs of the use environment, some also have a metal mesh cover. The floodlight with good performance is also equipped with an air filter. The electrical components are mainly ballasts, capacitors, triggers (designed according to the needs of the light source), etc.
