What are the misconceptions about golf course lighting design?

Golf course lighting system can extend the sunshine sport to golf under the starry sky, at the same time also can improve the utilization of the stadium operating revenue. This is to use the understanding of the lighting system is consistent, and some specific technical indicators and maintenance problems, there are a lot of understanding erroneous zone. Golf course lighting design at first, the brighter the better one, thought field and course management and industry contacts, we think the stadium lighting at night is as bright as possible, best can turn night into day. But that is not the case, the characteristics of golf decided it needs specific lighting effect. As you all know, golf is leisure and relaxation of sports, and football and basketball atmosphere of excitement and passion is just the opposite. So, golf course lighting is more suitable for use to compare downy light, let players feel like a walk in the moonlight swing and. Moreover, after a 9 hole golf need more than two hours, 18 holes more for more than four hours, so long time exposure to artificial light, player's eyes will feel tired. In addition, the brighter the pitch means more power consumption, from the consideration on the environmental protection and cost savings, the brighter the more good lighting concept is not correct. Two built early, light is very bright, will soon be dark phenomenon cannot solve it, on the golf course, the use of traditional exist in high power metal halide lamp lighting effect as the using time and waning phenomenon, and this also is the limits of metal halide lamp itself. This is known as droop, it is caused by the luminous principle of metal halide lamp itself. Exciting is, however, as represented by sound floating photoelectric lighting companies throw light on the LED research and development and improvement, technology innovation, is now able to quite perfect LED light source products well solved this difficult problem. Under the condition of new technology, maintain a constant pitch get no attenuation of lighting effect is no longer impossible task. Third, 100 - Light yellow light 150 w, 200 w, hair white light now there is a cognitive: heard the light 150 w that the light is yellow, and 200 w from the light source of the light is white. In fact, the yellow and white light has no direct correlation with the size of the power of light source, they are determined by the color temperature of light source. We can see in the standard chromaticity histogram and Planck curve, color temperature between 3200 k to 7000 k, are white light range, less than 3600 k yellow, slant blue light is larger than 7000 k. Fourth, to achieve the same lighting effect, low wattage of the lamps and lanterns will more than the number of lamps and lanterns USES high wattage, for example, we always habitually think than 200 w to 150 w lamps and lanterns of system systems use the lamps and lanterns of quantity. If only from the 150 w and 200 w two Numbers on the comparison, the conclusion seems to be logical. In fact, this conclusion is some judge a book by its cover, more or less will be decided by the efficiency. Usually 150 w rated flux for 15500 or 17800 lumens, and 200 w is 18000 or 20000 lumens, both exist droop. So, 200 w of the luminous flux from 10 to more than 150 w 30%, thus, achieve the same illuminance level, using 150 w system of lamps and lanterns, need to buy lamps and lanterns is more. And now the sound photoelectric IF - OFL16060 LED project-light lamp series, constant flux output is 13400 lumens, 200 w is 18000 or 20000 lumens, over a period of time will decay to 70%, at 12600 and 14000 lumens, below or quite close to the constant flux 13400 lumens and 150 w. Therefore, on the number of lamps and lanterns, 150 w system will not more than 200 w, this not only won't cause the cost increase of lamps and lanterns, on the contrary, it will also save operation electricity! Five, the stadium is bright, is the lighting effect is good this is one of the most common misconceptions. Usually, we see the stadium is bright, is refers to the field of the ground or the brightness of the surrounding environment, such as trees, and this is the level of lighting effect. Is also out of the lamps and lanterns of scattering the spillover of light, these are the direct light, more strong, less is soft. For the play, though, the vertical illumination in the air is more important, because the players must see clear white balls in the air flight trajectory, so the lamps and lanterns should have quite a number of light projected into the air, to ensure the lighting effect of the air. If the stadium looks very bright, the air in the vertical illumination effect is very poor, is a failure of lighting engineering. On the contrary, the appropriate level of lighting effect in combination with good vertical illumination, air is very ideal.
