The lux level of golf course lighting
With reference to the technical requirements of Japanese Illumination Standard (Z9110, 1997 edition) and Razorlux, the horizontal illuminance of the fairway portion is required to reach 80-100 lx, and the vertical illuminance is required to reach 100-150 lx.
In any vertical plane, the ratio between the vertical illuminance and the minimum illuminance should not be greater than 7:1 (Figure 2). When the ball is run at a speed of 100kmöh or higher, the vertical illuminance of the fairway is sufficient to allow the golfer to see the entire flight of the ball until it sees its ball drop.
Illumination of golf course lighting
The golf course led lighting illuminance of the fairway shall ensure that the golf ball hit by the golfer from the tees can be traced. For this purpose, the pole of the first vertical plane from the tees shall be not less than 30m.
The distance between the poles must be combined with the light distribution characteristics of the selected luminaires and the topography of the poles. The minimum installation height of the luminaire is 11m from the base of the lamppost, and it should be installed in the falling area of the ball or the bend of the fairway as much as possible.
This will reduce the number of lamps and poles and save investment. If the poles are located in special terrain, the installation height should be increased or decreased accordingly. So, in order to reduce the influence of the terrain. The light poles are generally installed along the ball lane or in higher areas.
The other part of the fairway, ie, the obstacle site on site, such as the bunker pond, bridge, etc., should also consider certain illumination illuminance, which can be between 30 and 75lx to ensure that the golfer hits the ball in these areas.
You can also successfully hit the ball again. At the same time, properly designing these golf course night lighting can also add some charm to the night court.
The golfer hit the ball through the fairway, hitting the ball to the green, pushing the ball into the hole and completing the hole. Green, as the end of the hole, the terrain is generally higher than the fairway, and its horizontal illumination is very demanding.
The general requirement is between 200 and 250 lx, and the ratio of the maximum horizontal illumination to the minimum horizontal illumination is not greater than 3:1. Since the golfer can push the ball from all directions to the hole in the green, therefore,
Design lighting in the green area to have at least two directions of illumination, minimizing shadows (Figure 3). The poles are installed in the shaded area 40 degrees in front of the green area, and the distance between the fixtures is less than or equal to three times the pole height.
