Common Misconceptions about LED Street Light
Several discussions have been going on about the possible negative effects of LEDs. In the process, many misconceptions have come up because of the lack of information about LED street lighting. Let’s discuss these myths and make important clarifications.
Myth 1: LED Street Lights Are Dangerous to People
The focus here should not be on the type of light but more on the amount of blue light emitted by the light source. LED lights have a wide range of color temperatures. LEDs are available in 3000K-4000K, a good choice for street lighting. The amount of blue light is so limited that it doesn’t affect people.
Myth 2: All Blue Light Is Dangerous To People
Blue light plays an important role in human health. It’s part of sunlight and enhances physiological human processes. The issue with blue light comes with over exposure at night time. Too much blue light may affect sleeping patterns.
Myth 3: LEDs Emit More Blue Light than Other Street Lights
During the initial stages of LED, the products emitted a significant amount of blue light. Improvements ensure LEDs produce limited blue light without affecting their efficiency and quality. Compared to conventional lighting, LEDs have the ability to generate directional light. This means they provide equal illumination with less light, decreasing blue light emission.
Myth 4: Street Lighting Should Not Emit Blue Light
Street lighting benefits from having some blue light. Blue light is part of what makes up the light spectrum that enhances street safety and aesthetics. Light sources that contain some blue light make objects appear more natural, help with proper identification of objects and people, and enhance visibility at low illumination levels.
Myth 5: The Streets Are Better With Traditional Street Lights than LED
For years, major cities used conventional lighting like fluorescents, HPS and MH lamps. But these lights became unpopular because their lighting is harsh. They are expensive to maintain and consume high electricity with a short lifespan.
Also, while traditional lights have no control over how much light they give off. LED lights emit focused light that adjusts to the preferred level and intensity. This reduces glare, light trespass, and light pollution. Without a doubt, the streets are better with LED street lighting.
