Abstract
The utility model relates to an optical lens used on the LED cold light source lamps. A lens body is combined into a whole by a lens surface and a frame, a plurality of refraction light condensing bowls with identical sizes and identical structures and arranged orderly are arranged in the lens surface, the bowl bottom of the refraction light condensing bowl is putted on the inner side surface of the lens surface, and the bowl opening thereof directs towards the outward side surface of the lens surface. The refraction light condensing bowl presents an elliptical vertical bowl shape, the slope included angle of the bowl body in the long shaft direction is 120 degrees, the slope included angle of the bowl body in the short shaft direction is 60 degrees, and a light inlet hole is arrange at the bowl bottom; and the lens body is made from optical grade acrylic acid resin. The optical lens has the advantages that the light spot radiated from the lens is rectangular, the uniformity of the light intensity is very good, the difference between the center of the light spot and the edge brightness is very little, and no difference with the extension direction of the of the roadway exists, which is completely consistent with the continuous extensibility of the roadway, the ideal brightness and the uniformity of the road surface can be ensured, simultaneously, the glare of the LED is eliminated, and the LED light energy utilization efficiency is exerted to be the acme, and no light pollution is caused.
Description
Technical field
The utility model relates to a kind of lens, is meant the optical lens on a kind of LED of being used for cold light source light fixture especially.
Background technology
The LED lighting engineering relies on its outstanding energy-conservation performance through years of development and accumulation, has entered the fast traffic lane of commercialized development.And in the illumination power consumption of whole country, account for 20～30% as the road lighting of illuminating industry important component part, with a very important position.But directly influence the light efficiency of LED as the quality of road illuminating lamp luminous intensity distribution, if adopt light-configuration mode commonly used, as the catoptron luminous intensity distribution, effect is just not satisfactory, because LED generally is cylinder, ball encapsulation, because the effect of convex lens, the former capital has very highly directive, be unidirection luminous, not satisfactory with the catoptron light distribution effect, the hot spot that is incident upon on the road surface is circle, and its hot spot effect is middle bright, the edge is dark, illumination uniformity coefficient extreme difference.And for example adopt the U type to arrange and improve the illumination uniformity coefficient, this scheme dazzle is serious, is not suitable for road lighting.Therefore how resolving the luminous intensity distribution problem becomes the key that can the LED lighting engineering be widely used in the road lighting field.
Summary of the invention
The purpose of this utility model is to provide a kind of can rationally control distribution of light, guarantee desirable brightness and uniformity coefficient, the elimination dazzle be used for optical lens on the LED cold light source light fixture, it is specially adapted to road lighting.
The purpose of this utility model is realized by following technical scheme, the mirror body is combined into one by minute surface and frame, the refraction convergent bowl that a plurality of sizes are identical, structure is also identical is arranged orderly being arranged in the minute surface, the bowl end of refraction convergent bowl, place the medial surface of minute surface, and its rim of a bowl is towards the lateral surface of minute surface.Refraction convergent bowl ovalize solid is bowl-shape, and long axis direction bowl body gradient angle is 120 °, and short-axis direction bowl body gradient angle is 60 °, and a light well is established at the bowl end; The mirror body is made by the optical grade acryl resin.
Design concept: when each LED cold light source respectively correspondence enter at the bottom of each refraction convergent bowl bowl in the light well, reflect at the bowl inwall, behind the optically focused, rectangular light beam penetrates from minute surface, because the orderly arrangement of each refraction convergent bowl, each rectangular light beam that penetrates evenly is connected naturally, therefore make the distribution of light that penetrates from lens even, brightness is big, does not have dazzle.
The utility model has the advantages that: from the hot spot rectangular (rectangle) of these lens ejaculation, the illuminance homogeneity is splendid, spot center and edge brightness difference are very little, with road bearing of trend indifference almost, meet the continuous extensibility of road fully, when having guaranteed desirable road surface brightness and uniformity coefficient, also eliminated the dazzle of LED, and it is ultimate attainment that the LED efficiency of light energy utilization is performed to, and do not have light pollution.

Fig. 2 is the medial surface structural representation of optical lens.
Fig. 3 is the A-A sectional view of Fig. 1.
Embodiment
Optical lens described in the utility model, as shown in Figure 1 and Figure 2, the mirror body is combined into one by minute surface 1 and frame 2, arranges the orderly refraction convergent bowl 3 that a plurality of sizes are identical, structure is also identical that is provided with in the minute surface 1.Refraction convergent bowl 3 in the present embodiment has 66, and the bowl end of refraction convergent bowl places the medial surface of minute surface, and its rim of a bowl is towards the lateral surface of minute surface.Refraction convergent bowl 3 ovalize solids are bowl-shape, and long axis direction bowl body gradient angle is 120 °, and short-axis direction bowl body gradient angle is 60 °, and a light well 4 is established at the bowl end; The mirror body is made by the optical grade acryl resin.
In the use, arrange orderly LED cold light source respectively correspondence respectively reflect convergent bowl 3, light enters at the bottom of each refraction convergent bowl bowl in the light well, reflect at the bowl inwall, optically focused, because the rising angle of the long axis direction of refraction convergent bowl is 120 °, the rising angle of short-axis direction is 60 °, therefore rectangular light beam penetrates from minute surface, because the orderly arrangement of each refraction convergent bowl, each rectangular light beam that penetrates evenly is connected naturally, meets trend of road, and distribution of light is even simultaneously, brightness is big, does not have dazzle.
Claims (4)
