Someone made the beeswax candles around the third century BC. In the 18th century, the paraffin candles had been produced and began to produce by machine. The British invented the gas lamp made a major step forward of human lighting represent 100 years ago. Torches, candles, oil lamps and gas lamps are all emitted by biomass burning to light and can not left to the fire. In the late 19th century, Edison invented the electric light which rewritten the history of human lighting and it foreshow mankind towards the era of electric lighting. The LED flashlight road lighting energy-saving needs conditional premise. For example, 360W or 350W light source will be able to achieve the design scale delineated in the backbone of the road. In this case, the 400W high pressure sodium lamp can not reduce the power and become powerless. The LED lights will be able to demonstrate its energy-saving effect by the construction of regulatory. Energy-saving premise is also reflected in its configuration of the intelligent control. LED lighting coupled with an intelligent control system is better to save energy. The strong light source is also the one of major feature. If there is no proper way to use the strong light source, it can easily cause the light pollution. We should consider designing the suitable lamps based on the detailed road because the LED flashlight road lighting energy savings also need to consider the environmental factors. For example, many companies produced a giant lamp with average illumination value may be not suitable for road lighting even though the bright is enough. The use of LED lighting should also consider the visual needs of pedestrians and drivers.
