Problems solved by technology

[0003] At present, the main problems of tunnel lighting are: the spectral energy in the wavelength range of 480nm to 580nm is low. Compared with sunlight, the spectral wavelengths of the above lamps are discontinuous. Or greater than sunlight, but because the visual distance of the human eye is much smaller than the sunlight environment, the problem of high brightness and short sight distance often occurs in the tunnel environment, which affects the safety of driving

Abstract

The invention discloses tunnel illumination lamps and a tunnel illumination system capable of improving a visual range. Each of the tunnel illumination lamps comprises a substrate provided with a light source assembly, wherein a luminous film coats the surface of each of the substrates; each of the luminous films contains a luminous material; the theoretical chemical composition of the luminous materials is as follows: M(1-x-y-z)Al2O4:xEu<2+>,2xDy,yR<3+>,zCe<3+>; the tunnel illumination system comprises the tunnel illumination lamps which are symmetrically mounted on the height, being 2.0 m to5.0 m, of the two sides of a tunnel arched wall; and a plurality of retroreflective induction labels are arranged on the arched top which is positioned between the tunnel illumination lamps. According to the tunnel illumination lamps and the tunnel illumination system capable of improving the visual range disclosed by the invention, the effective visual range of human eyes in a light environmentis effectively improved, the phenomena of black holes and blind light of entrances and exits of tunnels can be eliminated or reduced, and the safety during driving is ensured.

Description

technical field [0001] The invention relates to the technical field of tunnel lighting facilities, in particular to a tunnel lighting lamp and a tunnel lighting system capable of improving sight distance. Background technique [0002] In the prior art, the tunnel is an engineering building buried in the ground. Compared with the road on the ground, the tunnel cannot rely on sunlight for lighting, and can only be equipped with lights that are turned on throughout the day to realize tunnel lighting. LED (Light Emitting Diode, Light Emitting Diode) lamps are usually used as lighting lamps for tunnels because they have the advantages of long life, low light decay, good color rendering, and good vibration resistance. [0003] At present, the main problems of tunnel lighting are: the spectral energy in the wavelength range of 480nm to 580nm is low. Compared with sunlight, the spectral wavelengths of the above lamps are discontinuous. Or greater than sunlight, but because the visu...
