Spotlight encyclopedia knowledge


The spotlight can aim in any direction and has a structure that is not affected by climate conditions. It is mainly used in large-scale operation field, mine, building outline, stadium, overpass, monument, park and flower bed, etc. Therefore, almost all outdoor large area lighting lamps can be regarded as projection lamps. The angle of the beam emitted from the projection lamp varies from 0 ° to 180 ° and the beam with a narrow beam is called a searchlight.


Performance characteristics of spotlight

  1. The internal and external strong shock resistant structure design is adopted to effectively solve the problems of light bulb falling off, bulb life shortening and bracket fracture caused by strong vibration.
  2. With high efficiency gas discharge lamp as light source, the service life of bulb is longer than 10000 hours, especially suitable for outdoor large area unattended lighting.
  3. It has good electromagnetic compatibility and will not cause electromagnetic interference to the surrounding environment.
  4. The overall heat dissipation of the lamp is good, which can reduce the failure probability.

Installation method of spotlight

The projection lamp can be installed and used individually, or combined with multiple lamps, and installed on the pole above 20m to form a high pole lighting device. In addition to the features of beautiful appearance, centralized maintenance, reducing lamp pole and floor area, the biggest advantage of this device is strong lighting function. When the light is projected from a high place, the space brightness of the environment is high, and the light coverage is large, which gives people a feeling similar to the day, so it has a higher lighting quality and visual effect. In order to meet the minimum safety performance requirements for outdoor use, the enclosure protection grade of projection lamp shall be IP3 (open type). In order to improve the durability of lamps and reduce the workload of maintenance, people pay more and more attention to the development of airtight projection lamps with higher one-time investment cost. The enclosure protection grade is IP55. In order to further improve the light output ratio of lamps and lanterns, the reflectors tend to adopt the block reflector which can reduce the light barrier of the light source and the multifocal reflector which can meet the special lighting requirements; the surface treatment of the reflector tends to adopt new materials and new processes to obtain a reflectance of more than 96%. In order to lighten the lamp weight and reduce the consumption of metal materials, the shell of the lamp will develop towards the plastic shell with high temperature resistance, high mechanical strength and anti-aging.
