To play golf at night, there must be lighting with sufficient illumination, and golf courses have very high requirements for lighting. Golf course lighting requirements are different from other sports field lighting, and the issues to be considered are different from other sports fields. The golf course has a large area, many times larger than other sports fields, and is divided into many fairways. For a golf course with a par of 72, there are 18 fairways and 18 holes. In addition, the direction of the fairway is basically one-way, and most of the adjacent fairways are one-way, and the terrain of the fairway is varied, with ups and downs, so that the positioning of the light pole, the type of light source and the direction of the light projection of the lamp are obviously different from other sports fields. Different, it appears that the design is more complex and challenging. AIKO Lighting will share with you the design principles and product considerations of golf course lighting.
The first is the design principles of golf course lighting. In the tee area, the best position of the light pole is directly behind the tee, which can effectively prevent the golfer’s shadow from covering the golf ball. Particularly long tees may require two light poles to provide lighting. At this time, it is necessary to prevent the light poles near the front tee from interfering with the back tee.
In the fairway area, the lights on both sides must meet the remaining light to meet the requirements of seeing the ball falling on both sides of the fairway, while minimizing the glare to the adjacent fairway. For narrow fairways (the width of the fairway is less than twice the height of the light poles), it is best to arrange the light poles crossed on both sides to minimize the number of light poles. For fairways that are more than twice the height of the light poles, the light beams must cross and overlap when projected by the lamps. In order to obtain better uniformity, the distance between the light poles is required not to exceed 3 times the height of the light poles. All lamps must project in the same direction as the batting ball, with glare controllers and other related accessories.
The green is illuminated in two different directions in opposite directions, which reduces shadows on the golfer’s putt. Light poles must be arranged within a range of 15 to 35 degrees from the centerline of the green. The front 15-degree limit is mainly to reduce glare to the golfer, and the latter is mainly to prevent lamps from interfering with hitting the ball. The distance between the two light poles should not exceed 3 times the height of the light poles, and there must be no less than two light fixtures on each light pole. If there are bunkers, waters, fairways or other obstacles, you must separately Consider the number of fixtures and throw angles.
Regarding the selection of the beam type of lamps, in order to obtain better uniformity and reduce glare, we must use lamps with wide beams when providing horizontal illuminance to tees and greens, rather than to obtain higher illuminance data. A type of light fixture with a narrow beam. For fairway lighting, lamps with different widths and narrow beams must be used in combination to obtain better lighting effects. Wide beam lamps should be used first. The more light distribution curves available for lamps and lanterns, the better the lighting design effect can be obtained.
The following are product considerations for golf course lighting.
1) Prioritize the selection of high-efficiency light sources. In this way, when the same illuminance is achieved, the number of light sources required can be reduced, thereby reducing the cost of electrical circuit materials and installation costs, that is, reducing the initial investment.
2) Choose a light source with high color rendering and high color temperature. According to field practice, LED lights with a color rendering index of R a> 90 and a color temperature of over 5500K can well reproduce the appearance of the stadium, such as the original colors of lawns and balls.
3) Choose a light source with good control characteristics.
4) Select lamps that match the light source. That is, the structure is matched with the type, and the specification is matched with the power of the light source.
5) Select lamps that match the environment. Since the lamps of the golf course are installed in the outdoor open-air field, when selecting lamps, the degree of protection of the lamps against foreign objects and water and the degree of protection against electric shock must be fully considered. In addition, the anti-corrosion performance of lamps and lanterns must be considered in combination with the local atmospheric environment.
6) Choose lamps that can make reasonable use of the light distribution curve. In order to improve the light efficiency and reduce the loss of electric energy, at the same time, it is required that the lamps should have a good light distribution to reduce the damage of glare.
7) Choose lamps with high economical efficiency and light sources with low operating costs. Mainly consider the utilization factor of lamps, the life of lamps and light sources, and the maintenance factor of lamps.
8) Selection of light poles. The common ones are fixed type, tipping type, pneumatic lifting type and hydraulic lifting type. How to choose must be considered in combination with the stadium environment and the economic strength of the investment operator, on the premise of not affecting the environment of the stadium and ensuring the natural beauty of the stadium.
AIKO products are equipped with high uniformity to meet the lighting needs of golf courses. This keeps the overall brightness level more or less the same. Then there is flicker-free lighting, which allows high-speed cameras to capture the movement of golf balls and clubs.
AIKO products are available in a variety of color temperatures from 2700K to 6500K, depending on the needs of the golf course. A high color rendering index of over 85 helps to highlight the golf ball and create a contrast between the dark environment and the grass surface.
Choose AIKO products to provide your golf course with lightning protection, high-quality products that meet the needs of waterproof and anti-collision, and can also work normally in wild weather.
