The lights which are used to illuminate the roadways, streets, parks, and other public places are known as streetlights. The main purpose of using streetlights is to make the environment friendly for humans. Because people are afraid of going outside at night and feel weird walking in the dark, the government arranged streetlights in different areas. The well-developed countries have high-quality streetlights in every street—additionally, the rain, storms do not affect the efficiency of streetlights. These lights help to avoid road accidents on the road in the nighttime. There are various types of streetlights, but LED lights are the best. there are few myths about the LED light
Myth 1: LED Streetlights Are More Harmful to Humans and Animals Than Other Types of Streetlights
LED streetlights don’t cause more harm to humans and animals than any other kind of streetlights. This is because it doesn’t depend on the type of streetlight but directly depends upon the amount of light falling in short wavelengths known as the blue part of the spectrum. And LED streetlights control the amount of short-wavelength which they are emitting.
Myth 2: LED Lighting Emits Lighter Than Any Other Lighting Technology Available.
LED lighting products used to have a very short wavelength of light because the technology was in the initial stages of development then. However, many modifications have been made, and LEDs are now designed to emit very little and short-wavelength light without any drop in efficacy.
Myth 3: All Short-Wavelength Light Is Harmful to Both Animals and Humans:
Short-wavelength light is a basic component of the natural world. It plays a very important role in maintaining circadian rhythm. Excessive exposure to short-wavelength light may disturb your sleep patterns immensely and negatively affect your mental and physical health.
Myth 4: Communities Are Better Off With Conventional Street Lighting:
Most streetlights in the United States have been using High-pressure Sodium technology, which emits orange-yellow lights. HPS streetlights are now replaced by street lighting technology that emits white lights due to their higher efficacy and longer life span. It also offers various potential benefits like LED systems can be adjusted to provide the needed level of illumination at any time and provide great control over which light is being emitted. Thus, it helps in reducing glare and up the light of “Sky Glow” which reduces the visibility of stars in the night sky.
Myth 5: Street Lighting Should Never Emit Any Short-Wavelength Light:
Short wavelength lights are an important component of the visible light spectrum, and their benefits range from aesthetics to safety. For example, white lights help in the identification of people and objects and their backgrounds.
Advantages Of Streetlight
- Ultraviolet light emitted by the conventional light source attracts nocturnal insects.
- To capture the lights emitted by lamps, streetlights require a reflector. This reflector absorbs some light. Moreover, the bulbs in fluorescent lamps and some other lamps also use some of the light. The refractor aids in projecting the light on the street in the required pattern but some of the light got wasted by going up to the sky
- We can avoid the light from going into the driver’s eye by directing the light downward to the road.
- Fluorescent lights are very efficient; in winter temperatures, they have less output.
- LED lights are very efficient. They consume less energy
- The average lifespan of LED streetlights is 10-15 years. This lifespan is approximately 2 to 4 times greater than the HPS.
- The maintenance cost of LEDs is low
- LEDs give the full brightness quickly. As a result, they don’t take time to heat up after being switched on, like other fluorescent and high-intensity discharge (HID)lamps, e.g., mercury vapor, metal halides, etc.
- LEDs can be restarted immediately after any power failure etc. On the other hand, mercury vapor, metal halide, and sodium vapor lamps lack this.
- LEDs don’t emit poisonous gases if they get
- Color rendering index means the ability to reproduce the exact colors of objects. Proper color rendering makes it quite easy for the driver to distinguish and recognize different objects.
There are a lot of myths about LED streetlights, but these are not true, just a misunderstanding. LED streetlights are best and have health benefits because LED streetlights are free of carbon and mercury, so these lights have no side effects. Moreover, these LED lights are low in cost and long-lasting. These LED lights are made of the convex mirror, so weather conditions like rainstorms and snowfall don’t affect the efficiency of LED streetlights.
How Do LED Streetlights Work?
The LED streetlights contain photocells that detect if the light is low or high. If these lights are low, then streetlights turn up in a few seconds to make the street brighter. If the light is high, it means in the morning, the streetlight will be off in the morning time.
Are Streetlights on All Night?
It totally depends on local authorities because they manage the street light function. In most places, its timing is 6 to 6, but authorities turn off streetlights in mid at night in a few places.
Are LED Lights Better Than Other Streetlights?
Yes, LED streetlights are way better than other types of streetlights because they are less costly, save energy, and are long-lasting.
Are LED Streetlights Better for Air Pollution?
Yes, LED streetlights are environmentally friendly because these lights do not contain mercury and lead. even these streetlights are brighter than other lights and do not take time to warm up
Are LED Streetlights Brighter Than Other Streetlights?
Yes, because the range of LED streetlights is between 40 to 120 lumens per watt
Which Mirror Is Used in LED Lights?
The LED lights have a convex mirror.
