Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further described with the specific embodiments.
Referring to fig. 1 to 3, the present invention provides a method for preventing glare during tunnel illumination, comprising: comprises the following steps;
step 1: as shown in fig. 2, a plurality of top grooves are cut along the ceiling of the tunnel, and colored paint is sprayed on the bottom surfaces 2 of the top grooves and the surface 6 facing the driver, and the colored paint on the bottom surfaces has a light reflecting effect;
step 4; as shown in fig. 1, a side groove 4 with an arc-shaped section penetrating through the whole tunnel is cut on the side wall of the tunnel, reflective paint is sprayed on the inner wall of the side groove 4 for a driver to determine the position of the side wall of the tunnel, and the light generated by the automobile headlamp can be more effectively collected due to the arc-shaped design;
The ratio of the top groove perimeter chiseled out by the ceiling to the whole tunnel perimeter is 1: and 3, the top groove of the lighting lamp 2 can reflect light comprehensively through the bottom surface 2 of the lighting lamp, so that the light emitted by the lighting lamp 1 can be diffused and paved on the tunnel part of the area from top to bottom by the top groove with the periphery.
The distance between the top grooves is 3m, and as the length of the vehicle body of the running motor vehicle is generally larger than 4m, the front vehicle can be clearly observed by the rear vehicle through the lighting lamps 1 of the top grooves at the interval of 3 m.
The width of the top groove cut out from the ceiling is equal to the light emitting surface of the lighting fixture 1, so that the light emitting effect of the bottom surface 2 can be maximized.
The light guide groove 3 and a top groove chiseled on a ceiling are of an integrated structure, the light guide groove 3 is of a semi-cone shape, the included angle alpha degree is 25-30 degrees, the light of the lighting lamp 1 is limited by the top groove, the light can only be vertically diffused downwards, but the light of the top groove can be guided out through the light guide groove 3 to irradiate a road section in front of the top groove, the blank of the illumination of the road sections among a plurality of top grooves is avoided, the direction of the light irradiated by the light guide groove is opposite to the driving direction of a motor vehicle through the included angle alpha and reflective paint on the bottom surface of the light guide groove 3, the dazzling caused by the opposite light outlet of a driver is avoided, the light guide groove 3 is a cone-shaped opening from large to small, the top groove interval of 3m is formed after the vehicle runs, the intensity of the light reflected by the light guide groove 3 is dissipated after the vehicle runs, and the light guide groove 3 is inclined, so that only a small part of the light is irradiated on a rearview mirror of the vehicle after the vehicle runs out of the top groove, avoiding glare caused by irradiating the rearview mirror.
The colored paint adopted by the bottom surface 2 of the top groove of the tunnel is high-reflectivity nano reflective paint, the reflectivity of the reflective paint is not lower than 90%, and the light of the lighting lamp can be effectively expanded to the whole top groove by adopting the high-reflectivity reflective paint.
The colored paint adopted by the side 6 of the top groove of the tunnel, which faces the driver, is light blue paint with the reflection coefficient of 0.4-0.5, and the light-colored paint with low reflectivity reduces the dazzling generated when the front of the vehicle runs and the driver looks at the top groove because the driver passes through the light guide groove 3, and reduces the dazzling generated when the light emitted by the lighting lamp 1 irradiates the driver from the side 6 of the top groove, which faces the driver.
The three side grooves 4 are arranged, the first ground height from bottom to top is 1.2m, the width is 10cm, the second ground height is 1.4m, the width is 10cm, the third ground height is 1.5m, the width is 10cm, the side grooves 4 and the widths are arranged to adapt to different motor vehicles, the height of the motor vehicle headlights is different, the height of the existing motor vehicle type headlights is adapted through the three side grooves 4 and the widths, and therefore the situation that a driver cannot observe the side wall of the tunnel easily due to height difference generated by the vehicle body headlights is avoided.
The lighting lamp 1 is provided with two light emitting surfaces, one of the light emitting surfaces is vertically downward under the shielding light of the top groove, the other light is irradiated on the bottom surface 2 of the top groove and then reflected to the light guide groove 3 to be diffused by the light guide groove 3, the light emitting surface of the lighting lamp is vertically downward, a segmented light effect is generated on a tunnel road section (the vertically downward light irradiates the roof when a vehicle passes through, so that dazzling is not formed on a driver), the visual perception of the driver is increased, and the visual fatigue of the driver is avoided.
The reflection coefficient of the light gray coating 6 sprayed on the side wall 7 of the tunnel and the ceilings 5 between the top grooves is 0.3-0.5, so that the serious reflection caused by the irradiation of automobile headlights on the wall body is avoided.
The specific embodiments described herein are merely illustrative of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the scope of the invention or exceeding the scope of the claims appended hereto.
