Abstract
The utility model discloses a road illuminating lamp, comprising a reflective cup, a light source and a transparent cover, wherein the light source is arranged in the reflective cup; the transparent cover is covered on the opening of the reflective cup; the axis of the light source is vertical to the transparent cover; the outside surface of the transparent surface is a smooth surface; the inside surface of the transparent cover is provided with a plurality of prisms which are composed of strip ribs; and the prisms are mutually parallel with each other. According to the utility model, the road illuminating lamp not only can obtain uniform light spots and has little dizzy light or no dizzy light, and can reduce the volume of the lamp.
Description
Technical field
The utility model relates to a kind of road illuminating lamp, relates in particular to a kind of light fixture that is applied to the branch road illumination.
Background technology
The light fixture (non-led light source) that is applied to road lighting at present generally all adopts single reflector to add the form of cover glass cover, and as shown in Figure 1,1 ' is reflector, and 2 ' is light source, and 3 ' is the cover glass cover.Light source in the reflector is parallel to or installs near being parallel to the road surface, adopt in such a way, dazzle is difficult to control, and in order to satisfy the needs of road lighting, certain restriction is arranged in the selection of light source, must select the long light source of light-emitting area length, the design more complicated of while reflector, volume is also bigger.
The utility model content
The technical problems to be solved in the utility model provides the good road illuminating lamp of the less and dazzle of a kind of volume control, can make that hot spot is even on the road surface, does not have obvious speck or blackening.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of road illuminating lamp, comprise reflector, be installed on the light source in the reflector and be covered in the diffuser of reflector rim of a cup, the axis and the diffuser of described light source are perpendicular, the lateral surface of described diffuser is a smooth surface, the medial surface of diffuser is provided with a plurality of prisms that are made of the bar shaped fin, and described each prism is parallel to each other.
Preferably, the lateral surface of described diffuser is plane or convex surface.
Preferably, the height of described a plurality of prisms, size and slope have nothing in common with each other or have only a part wherein identical.
Preferably, the prism that is positioned at both sides is milder than the prism in the middle of being positioned at.
Preferably, between the adjacent refraction by prism face by the free curve transition.
Preferably, described reflector is a rotary body.
Preferably, described diffuser adopts borosilicate safety glass material.
Compared with prior art, the utlity model has following advantage:
1. light source vertically is located at (promptly perpendicular with diffuser) in the reflector, can reduce the horizontal volume of reflector, and reflector can adopt rotational symmetric shape, and the reflector technical maturity of this shape is made simply, and expense is also lower.
2. light source vertically is located in the reflector, and the length of light source luminescent face is not had special requirement, has relaxed the selection face of light source.
3. diffuser itself adopts safety glass, and heat-resisting, safety need not to add in addition the light fixture cover glass.
4. the light that sends of light source is after reflective cup reflects, be integrated into approximate directional light, again through after having the diffuser of a plurality of prisms, light can be assigned to the zones of different on road surface, because the design of prism group can well be controlled the angle of emergent ray on the diffuser, thereby the dazzle of control light fixture that can be strict.
5. light can be assigned to uniformly the zones of different on road surface by a plurality of prism design of differing heights, size and slope on the diffuser, form rectangular hot spot, and guarantee that the hot spot on the road surface is even.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of the road illuminating lamp of prior art.
Fig. 2 is the structural representation of road illuminating lamp of the present utility model.
Fig. 3 is the front view of diffuser in the utility model.
Fig. 4 is the vertical view of diffuser in the utility model.
The specific embodiment
Please refer to Fig. 2, road illuminating lamp of the present utility model comprises reflector 1, light source 2 and diffuser 3.Reflector 1 adopts parabolical Lamp cup or approximate parabolical Lamp cup, and adopts rotational symmetric shape, and this reflector 1 can be integrated into the light that light source 2 sends parallel rays or approximate parallel rays.Light source 2 is installed in the reflector 1 perpendicular to diffuser 3, can reduce the lateral length of reflector 1.Diffuser 3 is covered in the whole rim of a cup of reflector 1, and as shown in Figure 3, the lateral surface 31 of diffuser 3 is smooth plane or convex surface; The medial surface of diffuser 3 is provided with a plurality of prisms 32,33 that are made of the bar shaped fin, each prism (as shown in Figure 4) parallel to each other.The medial surface of diffuser 3 is towards light source 2, and the height of each prism, size and slope have nothing in common with each other or have only a part wherein identical, and the prism 32 that wherein is positioned at both sides is milder than the prism 33 in the middle of being positioned at.In the embodiment shown in fig. 3, contain the prism of 5 kinds of differing heights, size and 6 kinds of Different Slope on the medial surface of diffuser 3, wherein contain two asymmetrical prisms 32.Diffuser 3 itself adopts borosilicate safety glass material, and heat-resisting, safety need not to add in addition the light fixture cover glass.The light that the vertical light source of placing 2 sends, after the interior reflective surface reflection of reflector 1, be integrated into parallel rays or approximate parallel rays, after these light pass through diffuser 3 again, by differing heights, a plurality of prisms of size and slope are refracted to different zone, road surface respectively, form rectangular hot spot, the prism that slope is bigger arrives the road surface at a distance with light refraction, the slope smaller prisms arrives the road surface more nearby with light refraction, adjacent refraction by prism face 34, pass through the free curve transition between 35, realization light to even transition at a distance, obtains uniform hot spot from nearby on the road surface; Simultaneously, diffuser 3 time can be controlled the shooting angle of light well in design, makes the very little or complete free from glare of light fixture dazzle.
