Foretell bend type anti -dazzle grid and low lamp position light, the sheet metal tiling superpose that will form through buckling along longitudinal separation ground makes glare light at least through twice reflection when propagating between the double -phase adjacent sheet metal, can effectively reduce the produced glare of the reflection of light, improves coefficient of source efficiency, and low cost.
Description
Technical field
The utility model relates to lighting field, particularly relates to a kind of bendable anti-dazzle grid and low lamp position illuminating lamp.
Background technology
Building now, in the illuminating industry of road, architectural lighting, road lighting are widely used, and need a large amount of lighting apparatus thereupon.Present lighting apparatus not only involves great expense, weight large, and easily produces glare problem, and dazzle can make people feel dazzling, causes eyes to ache, shed tears and eyesight reduces, and people can be made time serious dizzy, even causes traffic accident or damage eyes.
For avoiding the generation of glare problem, the structures such as usual employing lens, reflective mirror or conventional grates, but lens are not only expensive and effect is unsatisfactory, although and conventional grates, diffuse reflection reflective mirror etc. to some extent solve glare problem, greatly detract light efficiency.Therefore need a kind of more effective and save technical measures.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of bendable anti-dazzle grid and low lamp position illuminating lamp, can effectively reduce reflective produced dazzle, improves source efficiency, and with low cost.
The utility model is achieved in that a kind of bendable anti-dazzle grid, and comprise multi-disc thin plate, each thin plate is bent to form continuously by certain bending angle, and its longitudinal section is roughly in wavy; Described multi-disc thin plate longitudinally tiles stacked, and there is certain intervals to each other; At least through two secondary reflections when dazzle light is propagated between two adjacent sheet of described grid.
Further, described gauge of sheet scope is 0.1-1.0mm.
Further, the cross section of described thin plate is rectangle, trapezoidal, polygon, arc or arc angle polygon.
Further, the bending angle scope of described thin plate is 2 ° to 6 °.
The utility model additionally provides a kind of low lamp position illuminating lamp, and comprise housing, light source and bendable anti-dazzle grid, described light source is arranged in described housing, and described bendable anti-dazzle grid is positioned at the side of described light source.
Further, the length of described thin plate and gap size adjust according to the size of described light source and lens.
Further, described low lamp position illuminating lamp, is characterized in that, the below of described housing is provided with the wind-guiding/mouth of a river can carrying out wind-force/waterpower cleaning fast.
The utility model compared with prior art, beneficial effect is: bendable anti-dazzle grid described in the utility model and low lamp position illuminating lamp, by longitudinally compartment of terrain by stacked for the thin plate tiling be bent to form, at least through two secondary reflections when making dazzle light propagate between two adjacent sheet, can effectively reduce reflective produced dazzle, improve source efficiency, and with low cost.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Fig. 1 to Fig. 5 is the bendable anti-dazzle grid shown in the utility model embodiment, comprises the multi-disc thin plate 1 be bent to form continuously by certain bending angle θ, and the longitudinal section of each thin plate 1 is roughly in wavy.Thin plate 1 longitudinally tiles stacked, and there is interval H to each other.At least through two secondary reflections when dazzle light r propagates between two adjacent sheet 1.
Concrete, thin plate 1 thickness range is 0.1-1.0mm, and it can be formed by plastic production, also can be made up of foil and be formed by lathe compacting, making material source extensive, with low cost, is conducive to economic reduction fixture deadweight.The cross section of thin plate 1 can make rectangle, trapezoidal, polygon, arc or arc angle polygon as required, is illustrated in figure 5 the bendable anti-dazzle grid that cross section is trapezoidal thin plate 1 '.In the present embodiment, for weakening the dazzle that light source imaging produces, thin plate 1 adopts translucent sheet plastic.
In addition, the utility model additionally provides a kind of low lamp position illuminating lamp, and comprise housing (not shown), light source 2 and above-mentioned bendable anti-dazzle grid, light source 2 is arranged in housing, and bendable anti-dazzle grid is positioned at the side of light source 2.The length L of thin plate 1 and the large I of interval H adjust according to the size of low lamp position illuminating lamp and illumination efficiency.Preferably, the below of this housing is provided with the wind-guiding/mouth of a river (not shown) can carrying out wind-force/waterpower cleaning fast.
In the present embodiment, this low lamp position illuminating lamp is street lamp, and thin plate 1 material is plastics.Through experiment, the dazzle that light r produces when driver is about 80 to 90 meters from the distance of street lamp is the most unfavorable.When light r through grid propagate into driver's eyes time, need ensure at least through two secondary reflections, so just can reach abatement dazzle object, therefore bending angle θ choose very important.Bending angle θ is too small, then can not realize two secondary reflections, and bending angle θ is excessive, then the light transmittance of grid can be caused too low, is incident upon the dark lighting on road surface, is unfavorable for road lighting.Known by test of many times, when bending angle θ is 2 °, only there is primary event in light r, and when bending angle θ is 6 °, the light transmittance of grid is lower, can not meet lighting requirement, therefore bending angle range Theta is 2 ° to 6 °.
For the street lamp of difformity and Different Light 2 size, need arrange suitable thin plate 1 length L and interval H to improve light efficiency, better to play anti-dazzle effect, usually, interval H is larger, and the length L of required thin plate 1 is longer.In the present embodiment, for reaching enough intensity and certain machining accuracy, the length L scope of thin plate 1 is 80-120mm, and the interval H scope between thin plate 1 is 2-5mm.
Bendable anti-dazzle grid described in the utility model and low lamp position illuminating lamp, by longitudinally compartment of terrain, the thin plate 1 be bent to form is tiled stacked, at least through two secondary reflections when making dazzle light r propagate between two adjacent sheet 1, can effectively reduce reflective produced dazzle, improve source efficiency, and with low cost.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
