LED Street Light Skd

The LED street light is an integrated lighting fixture that combines the LED panel with a heat sink. It is a common design for outdoor lighting fixtures. The heat sink is designed to dissipate the heat produced by the LED panels and prolong their lifespan.

LEDs are very efficient and last three times longer than standard high-intensity discharge (HID) lights. They also consume far less energy than other types of lights, reducing greenhouse gas emissions and maintenance costs.

They can also help reduce light trespass, a major problem in many cities. This is because LEDs are capable of producing a wide variety of colors. However, some experts are worried that they may cause problems for residents and wildlife.

Bright blue-rich white light can be especially problematic for residents who have dark skin, or are sensitive to the Purkinje effect - an eye condition that makes dark-adapted people more vulnerable to glare and other forms of light pollution. A recent study found that even a small amount of blue-rich white light can affect people's mood and their ability to sleep, and may have adverse health effects.

These concerns are why the American Medical Association recently issued a new policy statement about street lighting. The AMA calls for a shift to cool, diffused LEDs that can be dimmed or switched off when necessary.

Among the benefits of using LEDs is their long lifetime, which varies by application but is generally about 10 years. This is two to four times longer than the life of currently prevalent high-pressure sodium (HPS) street lights.

The lifetime of an LED street light depends on several factors, including the power output of the LEDs and the area of heat exchange between the LED panels and the heat sink. The design of the LED street light's heat sink is important to extending the life of the LEDs, because heat sinks can have as many grooves as possible to allow airflow and prevent heat from building up on the LED panels.

Another consideration is the color of the LEDs themselves. Different LEDs produce different colors, and the quality of the colors they emit can vary from one type to the next. Choosing the right color can help to ensure that residents, wildlife and night sky visibility are not negatively impacted by the streetlight.

Other factors that are critical to the longevity of an LED street light include temperature, humidity and dust. Fluorescent lights, for example, have a shorter lifespan than LEDs at colder temperatures because their lamps are usually sealed and do not provide an adequate airflow to promote effective cooling.

The American Dental Association has also urged the switch to cool, diffused LEDs for their potential to reduce glare and other light-related health concerns. Specifically, the AMA is concerned about the possibility of LED streetlights causing a deterioration in visual acuity, which can lead to difficulties in reading and driving.

This is why many municipalities are replacing their traditional high-pressure sodium street lights with more eco-friendly LEDs. While this is a great step toward the greener future, it does require careful planning and consideration. For example, the city of Pittsburgh is looking for a consultant to develop a citywide streetlight inventory, which will help to make sure that all the LED lights are placed where they'll be most effective and least harmful.
