LED stands for lighting emitting diode. LEDs are used in a lot of electronic products which includes the main topic I will be talking about today, street lighting. Street lighting technology has made use of LEDs since the 1960s. Prior to that the semi-conducting light source was used almost exclusively for products such as lamp indicators in electronic equipment. In recent years LED technology had increased considerably and the efficiency of this type of light emitter is far superior to the older semi conductor light source. As a result LED technology is now becoming common within new street lighting systems. LED pedestrian lights can be found in almost every city.
High Power LED street lights are new series of energy saving products that utilize high power LEDs as effective lighting source to traditional illumination, such as LPS, HPS, or MH street lights. Outdoor LED light provides a multitude of advantages over conventional incandescent light: LED street lighting is environmentally friendly, energy efficient, and cost-effective. Due to the international policy affection of low carbon and environmental-protection. LED street lighting, as an important member of public lighting family, have apply to many different countries with increasing need, which is to fit the requirement of low carbon and environment-protection.
Street-lighting, also known intelligent traffic controller that has a substantial part in maintaining the healthy activity in populated districts and is crucial for reducing injuries and street felonies; additionally, street lights are being utilized for creative and promotional goals. Apart from the energy usage, street lights might generate other issues that must be attended as blinding effect, accommodation reflex, illumination pollution and maintenance problems. The ideal solution for illuminating outdoor areas must supply a complete answer to all these aspects.
LED lighting is preferable because of their excellent color clarity and reliability and efficiency. Previously LED lighting has been used for marking landmarks and for decorational purposes. The amount of light omitted was generally not enough to make them suitable for street lighting. However as technology has improved it is now possible to set up LED lighting systems in a way that they emit a significant amount of light and so have become good at illuminating things and not just acting as visual markers. These consisted of being used for external lighting but now they are considered good enough to light our streets.
Now many traffic light suppliers are also leaning towards LED due to their power saving nature. Not just power saving, they also contribute towards a green environment.
