Darksky lighting solutions – Rifle street light

With the rapid development of urbanization, nighttime lighting systems have increased significantly, but shoddy lighting equipment has brought serious light pollution problems, destroying the natural night sky in the city. This not only affects people’s stargazing experience, but may also have a negative impact on the ecological environment, such as affecting animal migration and reproduction. In general, light pollution has serious environmental consequences for humans, wildlife and climate. According to the International Dark Sky Association (IDA), light pollution is caused by inappropriate or excessive use of lamps. The components of light pollution include the following. Glare: excessive brightness, causing visual discomfort ( – Find more to know how to reduce glare, etc ) ; skylight: brightening of the night sky above residential areas; light trespass: light falls on undesirable or unnecessary places; clutter: bright, chaotic, and excessive combinations of light sources. To reduce light pollution, the easiest way is to use DarkSky Approved lighting, and ZGSM’s Rifle street light just passed the certification in May this year. Here we will introduce why we should reduce light pollution by using Darksky lighting, the basic principles of controlling light pollution, and ZGSM’s efforts to control light pollution.

Benefit of Darksky lighting

Reduce light pollution: Darksky light(Darksky street light) controls the upward luminous flux of the light source to ensure that most of the light can directly illuminate the ground, thereby significantly reducing light pollution to the sky. This is critical to protecting the night sky and maintaining a good stargazing environment.

Protect the ecological environment: Excessive lighting at night will interfere with animal behavior patterns, such as migration and reproduction, and have a negative impact on the ecosystem. The application of Darksky light helps reduce this interference and protect the stability of the ecological environment.

Improve the quality of human life: Reducing light pollution allows people to better appreciate the night sky and enjoy stargazing. At the same time, a reasonable night lighting layout can also ensure the safety of people traveling at night and improve the quality of life.

Energy saving and emission reduction: Through the intelligent control system, Darksky light can automatically adjust the lighting brightness and range according to changes in time and ambient light to achieve energy saving and emission reduction. This not only helps reduce energy consumption, but also helps reduce greenhouse gas emissions, which has positive significance for environmental protection.

Basic principle of Darksky lighting

ZGSM Darksky lighting solution

In the previous section, we learned the basic principles of implementing Darksky lighting. Now we need to take appropriate measures to control glare, reduce over-lighting, and reduce the impact of light on unnecessary areas. ZGSM provides IDA-certified street lights. In addition, ZGSM ( Please review videos of ZGSM street light factory. ) provides lighting simulation to ensure that the lighting of the lamps is useful and does not illuminate unnecessary areas with reasonable light distribution. ZGSM’s lamps also support dimming to reduce unnecessary lighting after midnight. Finally, ZGSM’s lamps also have different color temperatures to choose from, 3000K or warmer. We will explain these one by one as following.

Spectrum(light distribution)

ZGSM lamps have different light distributions to choose from. Taking Rifle street lamps as an example, we have Type IIM, Type IIIM, Type IIS, Type IIIS and other light distributions. They can be applied to different road conditions(road width, pole spacing and height). They can ensure that the light is as uniform and as much as possible on the road, while reducing the light from unnecessary areas (such as residential areas and lawn, etc.). The most important and basic thing is that the BUG rating of ZGSM lamps is Bx-U0-Gx, which proves that these lamps do not irradiate upwards.

Lighting simulation

ZGSM provides free lighting simulation for all customers. The benefits of lighting simulation are two points: 1. You can know how many lamps you need and how these lamps should be distributed to achieve the required lighting results. 2. You can know the ULR of using these lamps. Below is the ULR rating in street lighting. To reduce light pollution, it is recommended that floodlights ( Please view the video of the DOB flood light ) /streetlights mounted horizontal to the ground. And to get a better lighting result (good uniformity and less spill lights), these lamps are better with asymmetric distributions.

CCT for selection

According to Darksky’s requirements, the color temperature of the lamp must be lower than 3000K, 2700K, 2200K, 1800K. ZGSM’s lamps support different color temperatures, including conventional 4000K, 5000K, 5700K and also warm color temperatures (<3000K) that meet Darksky’s requirements. But we need to remember that when the color temperature is lower than 3000K, the light efficiency of the lamp will also begin to decrease. If your project has requirements for light efficiency when Darksky lighting is also required, please be sure to consult ZGSM to achieve the light efficiency required by the project.

Dimming

Darksky recommends using controls such as timers or motion detectors to ensure that light is available when needed, dimmed when possible, and turned off when not needed. ZGSM’s lamps can achieve these functions. For example, by installing photocells on street lamps, we can turn on the lamps when it is dark and turn them off when it is daytime; by installing microwave sensors on street lamps, the lamps can turn off/dim when people leave and turn on when people come; by installing power supplies that support AstroDIM on street lamps (such as Inventronics, Osram, Philips), we can achieve lamps that illuminate the streets with different light outputs at different times of the night, for example, lamps illuminate the road with 50% light output from 22:00 to 5:00 to reduce unnecessary energy waste.

Summary

The significance of Darksky lighting(Darksky street light) is to reduce light pollution, protect the ecological environment, improve the quality of human life, save energy and reduce emissions, and comply with the concept of sustainable development. Through learning, we know that it is not that complicated to achieve Darksky lighting. A quick way is to use Darksky approved lamps. Of course, we can also achieve Darksky lighting through reasonable lamp design, active lighting simulation, reasonable lamp distribution and installation, reasonable lamp color temperature selection, and reasonable use of lamp dimming function. ZGSM’s Darksky approved street light ( Click here to view the video of the Leaf LED Street Light Fixtures. ) currently has Rifle series, which not only ensures people’s safety when traveling at night, but also actively avoids the impact of artificial light on the natural environment.
