The largest golf practice ground in Hokkaido, Japan (as shown on the left), has open courses of more than 200 yards and more than 140 batting positions. The practice center has automated service equipment and a perfect night lighting system to provide customers with an all-around golf service.
Before the retrofit of the lighting system, the night site lighting of the center took 1000 watts of high-pressure mercury lamp as the main light source, and the operating time of the practice site was easily affected by weather factors.
Main Problems Existing Before Retrofit
low energy utilization rate led light
light pollution is serious led light
night operations are affected by the weather led light
Increase The Power Saving Rate of The Site Significantly
High-Pressure Mercury Lamp
The whole lighting effect will be less than 50Lm/W with single light distribution.
FL2A LED Light
Full lighting efficiency exceeds 110Lm/W, modularization design for flexible power deployment; various optional lighting distribution, fully utilizing the light energy through the light distribution design.
40pcs 1000W mercury lamps replaced with 30pcs 400W LED lamps;
11pcs 400W mercury lights were replaced with 7pcs 200W LED flood lights and 4pcs 100W LED flood lights.
Fully Solve The Problem of Light Pollution
The dispersion of mercury lights causes light pollution and seriously affects the facilities close to the pitch. Light pollution should be reduced by laying a large shading net.
The network is expensive and difficult, and does not completely solve the problem of light pollution.
Through the precise light distribution design, the LED input lamps accurately control the light distribution to avoid light pollution to the surrounding facilities, and there is no need to use the light-shielding network.
In the drawing, the light is concentrated on the main site; the fence at the site edge is already in the dark, and basically, no escaping light can be seen.
Effectively Extend The Operating Hours
Before The Retrofit
Mercury light can only light down from heights as far as possible to reduce light pollution, so it needs to build a tall base tower.
The base tower is not only expensive with service life limit, but also needs to put the lamps based on safety considerations, and is forced to terminate the night operation.
After The Retrofit
LED lights through a systematic light distribution design, a variety of light matching combination use, effectively control light pollution without requiring "commanding" irradiation.
After the retrofit, the lamps were installed at the top of the venue, which not only saved the cost of renewal and maintenance of the tower, but also got rid of the constraints of night operation by weather factors, and effectively extended the operating time.
Effect After the Retrofit
Accurately Control The Lighting Range
Light up with more uniformity from near to far away.
Few Escape Light Overflow The Specified Area
No light pollution was caused outside the site.
Replace With Hpwinner Led Flood Lighting Advantages
Energy-saving efficiency is prominent, and the power saving rate of the lamps themselves reaches 70% (the final power saving rate exceeds 80%);
Accurate light distribution solves the problem of light pollution, and eliminates the shading network set up around the site;
Save the base tower, lighting is no longer affected by the weather, effectively extend the business hours at night;
With a variety of light distribution combinations, to achieve uniform lighting, the overall effect of the site has been greatly improved;
Use regional lighting control, adjust the lighting area of the site according to as necessary to further improve the power saving rate;
Reliability is improved, and spare parts and labor costs are significantly reduced.
