LED flood light is composed of three parts: optical parts, mechanical parts and electrical parts. The optical components are mainly reflectors and light-shielding grids that limit light. The mechanical parts are mainly the housing, and the focusing mechanism for fixing and adjusting the position of the light source. The brackets, bases and parts with angle indications that adjust the projection direction of the light beam are used to fix the lamps. For most of the enclosed LED floodlights, mechanical parts, protective glass and various sealing rings are very important. According to the needs of the use environment, sometimes it is also equipped with a metal mesh cover and a flood light with good performance, and it is also equipped with an air filter. Electrical components mainly refer to parts such as ballasts, capacitors, and triggers (set according to the needs of the light source).

The LED floodlight can be aimed in any direction, and it also has a structure that is not affected by climatic conditions. It is mainly used in large-area stadiums, overpasses, monuments, work sites and mines, building outlines, parks and flower beds. So basically all large-area lighting fixtures used outdoors can be regarded as LED floodlights. The exit beam angle of the LED floodlight is wide or narrow, and the range of change is about 0°～180°. Among them, the narrow beam is also called a searchlight.

The LED floodlight adopts a strong shock-resistant internal and external structural design, which effectively solves the problems of the bulb falling off, the bulb life shortening, and the bracket fracture due to strong vibration. With a gas discharge lamp with good effect as the light source, the service life of the bulb is about 10,000 hours or more, which is especially suitable for outdoor large-area unattended lighting. It also has good electromagnetic compatibility and will not cause electromagnetic interference to the surrounding environment. The overall heat dissipation performance of the lamp is very good, which can reduce the probability of failure.
