Abstract
The utility model relates to a street lamp reflector comprising an upper reflector and a lower reflector, wherein the lower reflector is annular, and surrounds a light source; the upper edge of the lower reflector and the light source are roughly at the same flat surface; the upper reflector is arranged above the light source, and is composed of two convex surfaces; the structure of the upper reflector is similar to a shell which is spread into 180 degrees; the lower edge of the upper reflector is roughly in an oval, the cross section is in an m shape; and the lower edge is lower than the light source and the upper edge of the lower reflector. The street lamp reflector can extendedly improve the evenness degree of the illumination intensity, the comfort and the running safety of street illumination, increase lamp intervals, and reduce the invest cost.
Description
Technical field: the utility model relates to a kind of street lamp (containing Tunnel Lamp) reflector.
Background technology: the light that street lamp is radiated on the road is made up of two parts: a part is to penetrate the light direct irradiation on the road surface under the part of light source; Another part is penetrated light and is reflexed on the road surface penetrating on the light source under light and the part by reflector.The transitional street lamps reflector is a concave shape reflector normally, this type of reflector will be penetrated on the light source when penetrating light and reflex on the road surface under light and the part, the Density Distribution of reflection ray on road is the same with the Density Distribution of direct projection light---and all be from the near local density height of light source, low more from light source density far away more, cause ray density to be thus: " highdensity direct light+highdensity reverberation " from the near road surface of light source, ray density from light source road surface far away is: " low-density direct light+low-density reverberation ", from the near to the remote, the ray density changes in distribution is big, cause the uniformity of illuminance on whole road surface low, be unfavorable for traffic safety, also cause the waste of the energy.In this case, improve the road uniformity of illuminance, certainly will increase street lamp and arrange density, thereby increase the cost of investment of road lighting, cause the waste of resource.
Summary of the invention: the purpose of this utility model be the weak point that exists at prior art and provide a kind of simple in structure, can increase the road illumination uniformity, reduce the road lamp reflector of road lighting cost of investment.
For achieving the above object, the technical solution adopted in the utility model is: a kind of road lamp reflector comprises upper reflector and following reflector.Following reflector is looped around around the light source in the form of a ring, and the upper limb of following reflector and light source are in the same plane substantially.Upper reflector is positioned at the light source top, is made up of two concave surfaces, and its structure is similar with the shell that is launched into 180 °, and its cross section becomes " m " font, and its lower edge is substantially oblong-shaped, and its lower edge is lower than light source and reaches reflector upper limb down.
The beneficial effects of the utility model are: increase substantially the road lighting uniformity of illuminance, improve road lighting comfortableness and travel safety, increase the lamp spacing, reduce the road lighting cost of investment.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1
Fig. 3 is the left view of Fig. 1.
The specific embodiment:
As Fig. 1---shown in Figure 3: a kind of road lamp reflector comprises upper reflector 1 and following reflector 3.Following reflector 3 in the form of a ring, be looped around around the light source 2, the upper limb of following transmitter 3 and light source 2 are on the same horizontal plane substantially, the effect of following reflector 3 is that light source 2 and the horizontal plane following light light of penetrating are at a slight angle reflexed on light source road surface far away, form a lamp shielding angle simultaneously, prevent the waste of dazzle and light.Upper reflector 1 is positioned at light source 2 tops, is made up of two concave surfaces, and its structure is similar with the shell that is launched into 180 °, and its lower edge is substantially oblong-shaped, and its cross section becomes " m " font, and its lower edge is lower than light source 2 and reaches the upper limb of reflector 3 down.The effect of upper reflector 1 will be penetrated on the light source 2 on the road surface that light reflexes to the same side, make the overwhelming majority on penetrate light and reflex to apart from light source 2 road surface far away, penetrate light on the fraction and reflex to apart from the nearer road surface of light source.
Operation principle: by changing the curvature of upper reflector, make with horizontal plane to become than penetrating light on the wide-angle to reflex to apart from the light source road surface far away, make with horizontal plane at a slight angle on penetrate light and reflex to apart from the nearer road surface of light source, allow the distribution of reflection ray on the road surface by from large to small as far as nearly density, opposite with the Density Distribution of direct projection light.After direct projection light and reflection ray are superimposed, ray density from the near place of light source distributes and is: " highdensity direct light+low-density reverberation ", ray density from light source place far away distributes and is: " low-density direct light+highdensity reverberation ", from the near to the remote, the ray density changes in distribution is little, the uniformity of illuminance on whole road surface is improved, improved the road lighting comfortableness, be beneficial to traffic safety.Owing to highdensity ray cast can be arrived the farther place, thereby can increase the lamp spacing, reduce the road lighting cost of investment.
The utility model can be widely used in street lamp (containing Tunnel Lamp) light fixture.
