Abstract
The utility model relates to a road lighting device, in particular to a low-installation-height road lighting device for a one-way lane, and solves the problems that the conventional high-pole road lamp is high in material consumption and high in energy consumption and the light of the conventional low-pole road lamp is easy to block. The road lighting device comprises lamps which are arranged on the roadsides of a road. The road lighting device is characterized in that the lamps are respectively arranged on the two roadsides of the road; the installation height of each lamp is between 0.2 m and 0.6 m; and a light beam of each lamp is emitted to the forward direction of a vehicle. The lamps which are arranged on a guardrail or an isolation belt are used for lighting the road, road lamp poles are eliminated, and materials are saved; the road lighting device is low in lighting height, low in lamp brightness requirement and low in energy consumption; and by complementation of lamp light on the two sides of the road, a lighting dark area which is formed by blocking the light by the vehicle is eliminated.
Description
Technical field
The utility model relates to a kind of road lighting device, particularly a kind of low-mounting height road lighting device of unidirectional track.
Technical background
Present road lighting comprises surface road, overhead, adopts high pole street lamp more, is main with the roadway lighting system of light projector from top to bottom.The high pole street lamp height is big, and generally more than four meters, illumination zone is also big, but this road lighting mode has several shortcomings: the first, use the lamp stand of high pole street lamp in a large number, and be a kind of great waste to materials such as iron and steel; The second, street lamp throws light on downwards from the lamp stand top, needs to guarantee the enough illuminances in ground, and it is big to expend electric power.
Patent Office of the People's Republic of China disclosed the CN101956944A patent on January 26th, 2011; Name is called street lamp and uses its roadway lighting system; This device street lamp comprises lamp stand and light projector type light fixture; Lamp stand is installed in road on one side, and light projector type lamp installation is on lamp stand, and wherein light projector type light fixture is along the road surface of road driving direction projecting beam to road.This device discloses lower lamp stand, and lamp stand is arranged on 0.2-0.5 rice.This device pole height is provided with low, the light fixture of still installing in road one side, if highly not enough, the vehicle that is gone easily blocks, and influences the visual field that rear side is sent a car.And this device still is provided with lamp stand and highly low, and the vehicle mistake that is formed is easily hit.
Summary of the invention
The purpose of the utility model is to solve that existing high pole street lamp consumptive material is many, power consumption greatly; And the problem that existing low pole line lamp light is prone to be blocked, the unidirectional track road lighting device that provides a kind of bilateral to throw light on.
The utility model solves the technical scheme that its technical problem adopted: a kind of road lighting device of unidirectional track; Comprise the light fixture that is installed in the road trackside; The roadside, both sides of said road all is equipped with light fixture; The lamp installation height is at 0.2～0.6 meter, and the light fixture light beam is the line direction projection before automobile.This device is suitable for unidirectional track, and light fixture is arranged on the both sides in unidirectional track, and projection forward, avoids light to face toward sending a car irradiation that the driver is produced dazzle.The road both sides are equipped with light fixture, and the illumination of both sides light fixture is complementary, when guaranteeing illuminance; Avoid vehicle to block a side lamp tool and shine illumination dark space into the vehicle opposite side; With two tracks is example, and when the right side light fixture was blocked in the driving of right lane, the left side light fixture can provide illumination for left-lane.The light fixture height is low, and the required lamp brightness of equal illumination degree is littler, and energy consumption is little.With roads such as city overhead roads is example, and the viaduct generally has two unidirectional tracks back and forth, is provided with guardrail between the unidirectional track and isolates, because the lamp installation height is low, the light fixture in two unidirectional tracks can not interact.
As preferably, before light fixture light beam projecting direction and the automobile line direction at horizontal plane projection angle at 30～60 degree.Select crevice projection angle according to light fixture irradiation sector, make all projections forward of whole illumination sector.
As preferably, said light fixture light beam and pavement of road angle are at 15～45 degree.Light is focused on the road surface as far as possible, and according to the lamp lighting sector, the illumination zone of assurance rear side light fixture and the illumination zone of front side light fixture are joined.
Said road both sides are provided with guardrail or isolation strip, and light fixture is directly installed on the guardrail or the side, isolation strip.Cancelled the setting of lamp stand, directly with lamp installation on guardrail or isolation strip, avoid vehicle mistake to hit.
As preferably, the alignment of the light fixture of said road both sides is provided with.
As other preferred version, the light fixture of said road both sides is crisscross arranged.The illumination zone that the light fixture that is crisscross arranged makes both sides is complementary more, and the dark place of illumination that is equivalent to shine at a side lamp tool opposite side is provided with the opposite side light fixture, the integral illumination good evenness.
As preferably, said lamp lighting zone is projected as sector region at horizontal plane, and the back side edge of sector region also projects light fixture the place ahead along vehicle traveling direction.
The utility model adopts the light fixture that is arranged on guardrail or the isolation strip to carry out road lighting, has save the setting of street lamp post, economical with materials; And illuminator level is low, and lamp brightness requires also low, and energy consumption is little; Adopt the complementary setting of road both sides light, avoid vehicle to block the illumination dark space of shining.

The specific embodiment
Below through specific embodiment and combine accompanying drawing that the utility model is further specified.
Embodiment 1: a kind of one-way road lighting device that is installed on overhead, and as shown in Figure 1.Overpass is two-way Four-Lane Road, middle isolates through guardrail 3, is separated into two unidirectional two tracks with overhead.Road 1 both sides of one way are equipped with guardrail 3, on the guardrail 3 of both sides light fixture 2 are installed all, and 2 alignment of road 1 both sides light fixture are provided with.Light fixture 2 has the fan-shaped field of illumination of 60 degree, and is as shown in Figure 2, and light fixture 2 projecting beam center lines and the vehicle angular separation α that moves ahead 45 spends, and guarantees that whole fan-shaped field of illumination all throws to light fixture the place ahead; As shown in Figure 3, light fixture 2 is forwards overlooked projection, and light fixture 2 projecting beam center lines and road 1 road surface angle β are 40 degree, and the leading edge and the lamp lighting zone, front side in rear side lamp lighting zone are joined.
Light fixture is installed respectively in the road both sides, and when a side lamp tool was blocked by driving vehicle, the light fixture of opposite side can guarantee road lighting brightness.The lamp installation height is lower than guardrail height, makes adjacent reverse unidirectional track can not receive the light influence.
Embodiment 2: the one-way road lighting device of a kind of arranged in dislocation on overhead, and as shown in Figure 4.In the present embodiment, road 1 both sides light fixture 2 is crisscross arranged, and makes road 1 one side lamp tools 2 be installed in the minimum position of opposite side lamp lighting brightness, makes the illuminance distribution of whole road more reasonable.Other structures are identical with embodiment 1.
