公路隧道新光源应用解析管理（Application and management of new light source for highway tunnel） The day before the Norway is blessed by the worlds longest (24.51KM) highway tunnel, the tunnel opened in November 2000 has been 11 years, in addition to a long distance, the tunnel lighting layout, perfect combination of functional and decorative, to help the driver and passengers show the connotation of light culture just perfect and uniform illumination, and continuous, spectacular, decorative lighting each 8~9 kilometers, so good to hear or see. Because of the rapid development of highway tunnels all over the world, the related lighting sources, lamps and lanterns, control, including the design, construction and energy saving are also discussed in this paper. The application of new light sources in tunnels is discussed. The worldwide use of various tunnels lighting products are mainly divided into four categories, the first category is the heating filament thermal radiation, such as incandescent lamps, halogen lamp, the light low light efficiency, high energy consumption, short service life, due to the development of tunnel lighting technology, has gradually been eliminated second other new light source; is a low pressure gas discharge lamp, mainly ordinary fluorescent lamp and electrodeless electromagnetic induction fluorescent lamp, low pressure sodium lamp; the third is the high intensity discharge lamps (HID), including high pressure mercury lamp, high pressure sodium lamp, metal halide lamp, and CosmoPolis light source; the fourth category is the solid-state lighting, such as LED chip. Among them, the gas discharge lamp process is mature, and there are many kinds of gas discharge lamps. With the improvement of light efficiency and power, LED has also been applied to general lighting and tunnel lighting in recent years. Based on the analysis of the characteristics of the new light source light-emitting principle, in recent years, and for the tunnel lighting quality, and with the
