The floodlight 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. The biggest advantage of this device is its strong lighting function, in addition to its beautiful appearance, centralized maintenance, reduced lamp posts, and footprint. When light is projected from a high altitude, the spatial brightness of the environment is high, the light coverage is large, giving people a feeling similar to daylight, thus having high lighting quality and visual effects. To meet the highest safety performance requirements for outdoor use, the housing protection level of the floodlight should be open. In order to improve the durability of lighting fixtures and reduce maintenance workload, people are increasingly paying attention to the development of sealed floodlights with high one-time investment costs, and their shell protection level is P55. In order to further improve the light output ratio of lamps, reflectors tend to use block surface reflectors that are conducive to reducing light blocking and multi focus reflectors that meet special lighting requirements; The surface treatment of reflective surfaces tends to adopt new materials and processes to achieve a reflection ratio of over 96%. In order to reduce the weight of lamps and reduce the consumption of metal materials, the lamp shell will develop towards a plastic shell with high temperature resistance, high mechanical strength and aging resistance.
