LED Street Lights – OMWLights(China)
LED street light also referred to as LED road lighting is an integrated -LED light fixture that is used for street lighting. OMWLIGHTS uses the LED chips of Brigelux,Cree and Epistar as its light source. The light source are considered integrated lights because, in most cases, the luminaire and the fixture are not separate parts.The LED light cluster is sealed on a panel and then assembled to the LED panel with a heat sink to become an integrated lighting fixture.
Different designs have been created that incorporate various types of LEDs into a light fixture. The current trend is to use high power 1 watt and COB LEDs. And some are several low power LEDs packed together to perform the same purpose as a single high power LED. The shape of the LED street light depends on several factors, including LED configuration, the heat sink used with the LEDs and aesthetic design preference. Heat sinks for LED street lights are similar in design to heat sinks used to cool other electronics such as computers. Heat sinks tend to have as many grooves as possible to facilitate the flow of hot air away from the LEDs. The area of heat exchange directly affects the lifespan of the LED street light.
Most LED street lights have a lens on the LED panel, which is designed to cast its light in a rectangular pattern, an advantage compared to traditional street lights, which typically have a reflector on the back side of a high-pressure sodium lamp. In this case, much of the luminance of the light is lost and produces light pollution in the air and surrounding environment. Such street lights can also cause glare for drivers and pedestrians. LED focus panels is that most light is directed to the road, and less light to the footpaths and other areas. This can be addressed by the use of specialized lens design and adjustable mounting spigots.
The primary feature of LED street lighting is energy efficiency compared to conventional street lighting fixture technologies such as high pressure sodium (HPS) and metal halide (MH). Research continues to improve the efficiency of newer models. LED street light can normally produce the same amount of (or higher) luminance as a traditional light, but requires only half of the power consumption. LED lighting does not typically fail, but instead decreases in output until it needs to be replaced.
There are many reasons why LED technology should be a consideration in street and area lighting. LED lights are environmentally friendly because they consume so little energy. They are free from hazardous chemicals such as mercury and lead which release toxins. They are not made with arc tubes like traditional HID but instead use diodes. Diodes help boost the resistance of the lamp giving them a higher rate of durability compared with other lamp technology, which ultimately provides a significantly longer lifespan. All of these factors, including higher light uniformity, improved color rendering and high color temperature, allowing for wider coverage, can reduce the wattage of fixtures required in many outdoor applications. This significantly reduces the cost of energy, and allows for lower cost of ownership over the life of the system.
