High mast LED flood light: generally speaking, it refers to a new lighting device composed of steel column-type lamp pole and high-power combined lamp holder over 15m. It is made up of lamp holder, internal lamp electric, rod body and foundation.
Lamp head can be shaped according to user requirements, surrounding environment, lighting needs specific and decided; The internal lamps are mainly composed of floodlights and floodlights. The light source is NG400 high pressure sodium lamp with a lighting radius of 60 meters.
The rod body is usually a cylindrical one-body structure, which is made of rolled steel plate. The height is 25 to 40 meters. It is made up of lamp holder, internal lamp electric, rod body and foundation. Lamp head can be shaped according to user requirements, surrounding environment, lighting needs specific and decided; Internal lamps and lanterns are mainly composed of floodlights and projection lamps.
The light sources are usually high pressure sodium lamps and metal halide lamps. The lighting radius is 60 meters. The rod body is usually a cylindrical one-body structure, made of steel plate, with a height of 15-40 meters.
(1) illumination of the high mast light. Municipal square: 15-25lx; Traffic plaza: 10~20lx; Commercial square: 10~20lx; Other squares: 5~10lx. The above illumination value refers to the minimum horizontal illumination value at D= 2.0h. In order to increase the three-dimensional sense of moving objects on the sports ground, the side lighting of the sports ground is carried out by the high-pole lamp.
(2) illumination uniformity. General square lighting has no specific requirements for illumination uniformity, but stadium lighting has higher requirements for illumination and illumination uniformity. The lighting intensity of the high-pole lighting area is generally the further away from the light pole, the lower the lighting value. In order to improve the intensity of illumination uniformity, can take the following measures:
1) adjust the aiming Angle project-light lamp
2) project-light lamp light to overlapping
3) with half high lamp, project-light lamp, added in the form of street lamps and lighting (3) the light color. High pressure sodium lamp is preferred in general traffic square and municipal square. It gives off orange color light. The place with high requirement for light color, such as sports square, commercial square, station square, etc., can choose the golden halide lamp with good color rendering. In the sports field of TV broadcasting, the high color gas discharge lamp such as golden halide lamp must be used for the high pole lighting source.
