The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail: Fig. 1 is total pictorial diagram of illuminator of the present invention, and it is made up of lighting 14a-14d, and it is one-sided to be installed in road.Fig. 2 is the lighting side view schematic diagram shown in Fig. 1.Fig. 3 is the schematic top plan view of one section road of lighting of the present invention.As a two-way primary highway, this part of highway is straight, and two tracks 10,12 are arranged.Lighting 14a-14d can be installed in the top of guardrail 16, is parallel to road axis near being installed in road.Also can select to be installed in lighting on the lamp stand or on other supporters.
According to the present invention as can be known, lighting 14a-14d should be installed in the place of 1.2 meters of vertical heights, preferably 0.9 meter.
Learn according to the present invention that equally first jiao of δ 1 minimum of a value of the light beam of each lighting is 45 °, second jiao of δ 2 maximum is 88 °, and first jiao is defined as relative with downward longitudinal axis X with second jiao.
The light beam that lighting 14a sends forms dihedron by first jiao of δ 1 and second jiao of δ 2, and this dihedron is defined as with respect to longitudinal axis X perpendicular to road.
First jiao about 45 °, this angle value is to define according to the distance that lighting and road edge are illuminated.
For second jiao of δ 2,, between 83 ° and 88 °, preferably 85 spend.The light that sends is tiled on the road.
Adopt this beam angle value that the road of wide D is illuminated, this width is 5.5 times to 12 times of light source setting height(from bottom) h, that is to say greatly between 5 meters and 11 meters.Such width can make the lighting of one-sided installation just can illuminate 3 tracks.
In addition, second jiao of δ 2 limits value of lighting are substantially at 88 °, have just at first alleviated car moves the time on road intrusion, have prevented the dazzle that the driver is caused again, the height h that has also determined thus to install is less than 1.2 meters, and this setting height(from bottom) is lower than the top of most of car doors.
The light beam that each lighting 14a-14d sends is with respect to vertical plane P symmetry, with road fully or almost completely vertical.
As shown in Figure 1, distribution of light is with respect to vertical plane P symmetry, and is vertical with road axis.Thereby this uniform illumination can be more suitable in two-way road.
In addition, lighting 14a-14d will be installed in the zone of about 8 to 15 meters spacing distance d, and this spacer makes road can obtain consistent illumination from d, particularly for two-way road.
In addition, vertical reflection sign 15a-15d can be installed on road opposite, lighting 14a-14d installation place.Certainly, this mode is only applicable to the situation of the one-sided setting of lighting.The utilization of above-mentioned reflective sigh make the sign on the road can be continuously, show that clearly this is very useful beyond doubt for the driver.
As depicted in figs. 1 and 2, lighting 14a-14d is installed in the one-sided of road.As shown in Figure 3, another kind of possibility, lighting is installed in the both sides of road.In this case, lighting 14e-14h is installed in the another side of road, with lighting 14a-14d over against.They are installed on the identical vertical plane P, perpendicular to road.
Thereby this positioned opposite can illuminate 22 meters wide road surfaces, just in time adapts with two-way six-lane double width road.
Now, in conjunction with Fig. 2 lighting device lighting light fixture of the present invention is introduced: lighting 14a is equipped with a specular reflector 18 that cylindricality is complex-curved, and the complex curve that the reflector section is had carries out accurate light distribution via digitlization software for calculation and equipment and calculates.
In addition, the axle of light source 20 is always complex-curved perpendicular to cylindricality, and the complex-curved formation reflector 18 of cylindricality.Also can adopt in reflector 18 same position that Different Light is installed and dispose native system.
The road lighting test is carried out on lighting device of the present invention and conventional illuminator simultaneously.Following table is listed the gained result, and compares according to the suggestion of the relevant road lighting of AFE issue and the European lighting criteria of AFNOR issue.This test is to carry out on the road of about 7 meters wide single faces illumination.The installation of the lighting of legacy system is 8 meters high, about 28 meters at interval spacing, and installation of the present invention then is 0.9 meter high, about 10 meters spacing.The light source that is installed on the traditional illumination system approximately is the power of 150W, and the power of the lighting of system of the present invention is 35W.
| The AFE suggestion | Legacy system | System of the present invention | |
| Mean flow rate (cd/m2) | (1.5 minimum) | 1.8 | 1.7 |
| Overall uniformity | (0.4 minimum) | 0.5 | 0.5 |
| Longitudinal uniformity | (0.7 maximum) | 0.8 | 0.75 |
| Disability glare (TI (%) | 15 (maximums) | 15 | 5 |
| Energy consumes (W/ml) | 6 | 4 |
On the one hand, we can see that mean flow rate (regulation that meets the road light flux reflected) is consistent with the AFE suggestion, and roughly identical with one of them legacy system.On the other hand, overall uniformity (ratio that is equivalent to minimum brightness divided by mean flow rate) and longitudinal uniformity (be equivalent on the wagon flow direction minimum brightness on the axis of every trade road divided by the minimum of a value of the ratio of high-high brightness) also meet the AFE suggestion and also equate with the traditional illumination system uniformity substantially.
Under this test condition, disability glare TI disturbs the people who is difficult for being ridden to feel as a kind of dazzle, and this ratio also is used for weighing its ultimate failure ability when finding potential barrier.This ratio is high more, and the bright more visibility of dazzle is low more.Calculating in these experiments shows, for the people who rides, compares the travels down that illuminates in traditional illuminator, and disability glare TI is much smaller than traditional illumination system by the travels down of lighting device lighting of the present invention the time.
In addition, illuminator average energy consumption of the present invention is more much lower than a traditional illuminator.Result in energy consumption has saved 50% energy.
The benefit that provides a lot of traditional illumination system not have by the illuminator and the equipment of the present invention prediction is provided with traditional illuminator.For example, the invention enables to the driver reduces dazzle and reduces the light of vehicle enclosure invaded and harassed and become possibility.Light distribution perpendicular to the symmetrical zero diopter of road plane can not cause any inconvenience and interference to the rearview mirror of the vehicles yet.
It should be noted that to be mainly used in to runway provides to plunder and penetrate illumination, and singly be not the vehicle on the runway by illuminator of the present invention and equipment.Provide at lighting and to plunder the visibility of penetrating when illumination driver and also improved.Light makes potential barrier of road and irregular road surface characteristic appear suddenly out to the grazing incidence of runway.This also makes observes fuzzy object by negative contrast and becomes and be more prone to.Because higher brightness has been arranged, the irregular negative contrast on barrier and road surface also remains on the higher level, and this makes the discovery object become and is more prone to.In addition, the grazing incidence of lighting also makes the brighter object that occurs under positive contrast be more prone to observe.
