In the past years, the potential impact of LED street lights on health and the environment has been a hot topic of discussion. With the development of dialogue, people have more and more misunderstandings and misunderstandings about LEDs. We have collected a series of useful resources on this topic to help clarify some light and clarify some of the most common myths about LED street lights.
Myth: LED streetlights are more harmful to humans and animals than other kinds of streetlights.
LED street lights are no more harmful to humans and animals than other types of street lights. The problem is not the type of light source, but the amount of short-wavelength light emitted, which is often referred to as the “blue” part of the spectrum. Moreover, unlike other types of street lights, LED street lights actually have the potential to control the short wavelengths they emit.
Myth: All short-wavelength light is harmful to humans and animals.
On the contrary, short-wavelength light is an essential part of nature. It exists in sunlight and has been shown to play an important role in many physiological processes, such as affecting the circadian rhythm (our 24-hour “biological clock”, which controls the sleep/wake cycle). Worryingly, excessive exposure to short-wavelength light at night may disrupt sleep patterns and produce other undesirable effects.
Myth: LED lighting emits more short-wavelength light than do other lighting technologies.
Indeed, early LED lighting products tend to contain more short-wavelength components, because this technology is still in the initial stage of development. However, since then, tremendous progress has meant that today’s LEDs can be designed to emit as little or as much short-wavelength light as possible without causing efficiency or other performance degradation. Led can also better control the irradiation position of the light. This means that they can usually meet the same lighting requirements as traditional street lights, while emitting less light-thereby further reducing any short-wavelength components.
Myth: Street lighting should never emit any short-wavelength light.
Most street lighting situations benefit from at least some short-wavelength content. Short wavelengths are a key component of the visible spectrum, and have benefits from beauty to safety. For example, a white light source containing short wavelengths can display the colors of objects more naturally, help identify people and objects, improve the contrast between objects and their backgrounds, and enhance peripheral vision under low illumination, which is usually the street. Characteristics of lighting.
Myth: Communities are better off with conventional street lighting.
In the past few decades, most street lighting in the United States has used high pressure sodium (HPS) technology, which emits orange light. HPS street lighting is being replaced by street lighting technology that emits “white” light-mainly LEDs, because of its higher efficiency and longer life. All white light technologies-including LEDs-emit more short-wavelength light than HPS. In addition to longer life and higher efficiency (which, by the way, can provide substantial energy and cost savings), LED street lights also provide other potential benefits. For example, unlike other types of street lighting, LED systems can be adjusted to only provide the required level of lighting at any given time, and can also provide a high degree of control over the direction of light emission. This makes it much easier to reduce glare, light intrusion (light overflowing to unwanted places) and upward light (which leads to the “sky glow” phenomenon, which reduces the visibility of stars in the night sky).
LED street lighting can play a critical role in avoiding unintended consequences to humans and wildlife – as long as care is taken to make sure the light is directed only where it is needed, with minimal glare, and that it emits a spectrum that supports visibility, safety, and health.
LED bulbs are gaining a huge market share, and this is for good reason. As you may know, LED bulbs are more energy-efficient, more environmentally friendly, and more cost-effective than traditional halogen lamps, metal halide lamps and high-pressure sodium lamps.
Taking into account the entire life cycle cost including installation, maintenance and energy, LED street lights provide the best economic return than traditional street lights.
Energy Saving: LED lights use 75% less energy than incandescent bulbs.
Money-Saving: LED lights can save you thousands in electricity costs over its lifetime.
Reduce Costs: LED lights can help reduce maintenance and operation costs.
Long-Lasting: LED lights can last for up to 30,000 hours.
Variety: LED lights come in a variety of styles, lumens and color temperatures.
Benefits of Switching to LED Street Lights
Reduces maintenance costs: Unlike high-pressure sodium street lights, LED’s light output does not depreciate over time, making maintenance costs of replacing them significantly lower.
Reduces operation costs: LED Street Lights can greatly reduce your utility bill, while still offering optimal brightness at a low wattage. They can also reduce energy consumption by 40 to 60 percent.
Increases Driver Safety: Brighter and greater illumination can largely increase safety for drivers at night.
Reduces your carbon footprint: LED technology has a lot of potential to reduce light pollution and reduce global energy use.
