Tunnel lighting light source and how to choose

from various parts of the highway tunnel environment introduction spectroscopic analysis, the light source and the choice of lamps and lanterns, tunnel in the daytime and nighttime lighting, lighting design points to the specific implementation case, led track lamp factory system to share with readers in the tunnel lighting classification: entrance lighting, basic lighting, lighting, emergency lighting, etc.

tunnel lighting steps: determine the tunnel type & rarr; Determine the tunnel brightness and uniformity & rarr; Determine the types of road tunnel to determine vertical illuminance, higher than standard & rarr; Select the appropriate light source and lamps and lanterns & rarr; Determine the lighting system, lamps and lanterns spacing & rarr; To calculate lighting effect, improve lighting solution.

the tunnel lighting light source, in addition to meet the requirements of general road lighting, especially to choose those formed in the automobile exhaust smoke, can still have good pervious to light. Therefore, in general, choose high pressure sodium lamp is given priority to; If short tunnel or mixed with diesel ratio of small urban tunnel, smoke less, can consider to good color fluorescent lamp or metal halide lamp. At the entrance of the out of the tunnel using big flux of high pressure sodium lamp and metal halide, with the development of LED technology and energy saving effect is obvious, best choice will be the future tunnel lighting.

in order to solve the black hole of the tunnel effect and scintillation effect, in addition to reasonable lighting design, more important is to choose reasonable tunnel lamps, to ensure that the vehicle safe passage in the tunnel.

the characteristics of the tunnel lamps and lanterns should be: A. The lamp body is special aluminum alloy material, anodic oxidation treatment on the surface, high strength, corrosion resistance; B。 Reasonable light distribution, higher luminous efficiency; C。 Energy consumption in sealing; D。 Can use suspension, and the way of direct fixed installation.

tunnel lamps and lanterns decorate

1) relative: relative and staggered general install lamps and lanterns is somewhere between metope and ceiling axis, not installed in the side, the reason is that in order to provide a good visual environment, make to 2 m high at the bottom of the tunnel wall within the scope of the average brightness of not less than the average brightness of the pavement.

(2). LED hutch to absorb dome light, LED flat light,

(3) in the middle: middle arrangement is the axis of the install lamps and lanterns at the zenith, maintenance is difficult, so will affect traffic, so generally do not take this way.
