Floodlights are lamps that specify that the illuminance on the illuminated surface is higher than that of the surrounding environment. Also called spotlight. In general, it is capable of aiming in any direction and has a structure that is not affected by climatic conditions. Mainly used for large-area mines, building outlines, stadiums, overpasses, monuments, parks and flower beds, etc. Therefore, almost all large-area lighting fixtures used outdoors can be regarded as floodlights. The angle of the outgoing beam of the floodlight is wide or narrow, and the variation range is between 0° and 180°. The beam with a particularly narrow beam is called a searchlight.

  Floodlights can be installed and used individually, or multiple lights can be combined and installed on a pole of more than 20m to form a high-pole lighting device. In addition to the beautiful appearance, centralized maintenance, and reduction of light poles and floor space, the biggest advantage of this device is its strong lighting function. When the light is projected from a high place, the spatial brightness of the environment is high, and the light coverage is large, giving people a feeling similar to daytime, so it has higher lighting quality and visual effects.

  In order to meet the minimum safety performance requirements for outdoor use, the enclosure protection level of the floodlight should be IP×3 (open type). In order to improve the durability of lamps and reduce maintenance workload, people pay more and more attention to the development of closed-type floodlights with high one-time investment costs, and their enclosure protection grade is IP55.

  In order to further improve the light output ratio of lamps, the reflectors tend to use block plate reflectors that are conducive to reducing light blocking and multi-focus reflectors that meet special lighting requirements; the surface treatment of the reflective surface tends to use new materials and new processes, to obtain a reflectance of over 96%.
