Embodiment Construction

[0024] This embodiment provides a five-segment division lighting setting method for one-way traffic or two-way traffic long tunnels. The method divides one-way traffic long tunnels or two-way traffic long tunnels into five lighting areas, wherein:

[0025] One-way traffic long tunnel lighting is divided into entrance dimming section, entrance transition section, middle section, exit transition section and exit dimming section; and entrance dimming section, entrance transition section, middle section, exit transition section and exit dimming section The brightness value is not less than 0.2cd / m 2 ;

[0026] The two-way traffic long tunnel lighting is divided into the first entrance and exit dimming section, the first entrance and exit transition section, the middle section, the second entrance and exit transition section and the second entrance and exit dimming section, and the first entrance and exit dimming section, the first entrance and exit transition section, The brightn...

Abstract

The invention discloses a five-section dividing lighting setting method for a long tunnel. According to the method, a one-way traffic tunnel or a two-way traffic tunnel is divided into five lighting areas, wherein lighting of the one-way traffic tunnel is divided into an entrance dimming section, an entrance transition section, a middle section, an exit transition section and an exit dimming section; the lighting of the two-way traffic tunnel is divided into a first access dimming section, a first access transition section, a middle section, a second access transition section and a second access dimming section; and the brightness value of each section is not smaller than 0.2 cd/m<2>. With the method, the original stepped multi-section transition set with change of the brightness outside the tunnel is simplified into existing dimming sections and the single transition section, and the brightness index considering the safety, the comfort and the economy is put forward. Lighting design, energy saving and emission reduction can be greatly optimized, and the characteristics of long tunnel lighting are met.

Description

technical field [0001] The invention belongs to the energy saving of long tunnel lighting in the technical field of highway tunnel lighting and the analysis and research on the change of driver's vision under the environment of long tunnel lighting, and particularly relates to a five-section division lighting setting method for long tunnels. Background technique [0002] In the mechanical and electrical systems of highway traffic tunnels, the lighting load accounts for about 30%. As the mileage of highway traffic tunnels increases, energy saving and consumption reduction has become a major research topic to reduce tunnel operation. The National Development and Reform Commission clearly puts transportation and green lighting projects as one of the key points of energy conservation. In order to reduce operating costs, some road traffic tunnels often use separate lights, unilaterally or not at all in the basic lighting section or reinforced section in actual operation to achie...
