Abstract
The utility model discloses a light emitting diode (LED) light distribution lens with good uniformity and high luminous efficiency. The LED light distribution lens comprises a lens body, wherein a groove used for containing LED lamp beads is arranged on the inner side surface of the lens body, and an area on the surface of the groove and at least capable of being irradiated by LED lamp bead light beams is a non-smooth surface capable of having diffuse reflection. The diffuse reflection surface is arranged on the inner surface of the LED lens corresponding to the LED light beams so that the LED light distribution lens leads partial light to be emitted out after being diffused through diffuse reflection, and is even in light distribution, free of glaring, good in light shape, high in light energy utilization ratio and obvious in energy saving.
Description
Technical field
The utility model relates to a kind of LED light-distribution lens, relates in particular to the high LED light-distribution lens of a kind of good evenness light efficiency.
Background technology
The LED light fixture has power consumption few, applicability is strong, response time is short, environmentally safe, advantage such as multicolor luminous, in lighting field, obtain application more and more widely, the light intensity distributions that LED sends is that optical axis is the strongest, radially weaken gradually all around from optical axis direction, optical axis place luminous intensity accounts for more than 70% of total luminous intensity, directly application causes Luminance Distribution unreasonable easily, the shortcoming that dazzle and the efficiency of light energy utilization are low, thereby adopt LED as lighting source, need to guarantee its uniformity, when the LED lamp is applied to road lighting simultaneously, need make the light can be along road length to evenly dispersing and shining on the road surface, with the further raising efficiency of light energy utilization.
Therefore, for addressing the above problem, need to adopt the secondary light-distribution technology carry out luminous intensity distribution again, avoid occurring that distribution of light is inhomogeneous, dazzle and the low problem of the efficiency of light energy utilization, guarantee lighting quality, energy savings.
The utility model content
In view of this, the purpose of this utility model provides the high LED light-distribution lens of a kind of good evenness light efficiency, and the corresponding LED light beam of its inner surface is provided with diffuse surface, can make part light disperse the back through diffuse reflection and penetrate, and light shape is good, and efficiency of light energy utilization height is energy-conservation obvious.
The LED light-distribution lens that good evenness light efficiency of the present utility model is high comprises lens body; The medial surface of described lens body is provided be used to the groove that holds LED lamp pearl; Irreflexive non-smooth surface at least can be by the zone of LED lamp pearly-lustre bundle irradiation for can take place in described groove surfaces.
Further, described non-smooth surface is to arrange the corrugated surface that forms by a plurality of fins;
Further, the exit facet of described lens body is ellipsoid;
Further, the fin of described non-smooth surface along the length of lens body ellipsoid to arrangement;
Further, described lens body feather edge is provided with fixedly step;
Further, the exit facet of described lens body is provided with anti-reflection film.
The beneficial effects of the utility model are: the LED light-distribution lens that good evenness light efficiency of the present utility model is high, and the corresponding LED light beam of its inner surface is provided with diffuse surface, can make part light disperse the back through diffuse reflection and penetrate, distribution of light is even, free from glare, and light shape is good, efficiency of light energy utilization height, energy-conservation obvious.

The specific embodiment
Fig. 1 is front view of the present utility model, and Fig. 2 is vertical view of the present utility model, and as shown in the figure: the LED light-distribution lens that the good evenness light efficiency of present embodiment is high comprises lens body 1; The medial surface of described lens body 1 is provided be used to the groove 2 that holds LED lamp pearl; Irreflexive non-smooth surface 3 at least can be by the zone of LED lamp pearly-lustre bundle irradiation for can take place in described groove 2 surfaces; Non-smooth surface 3 can be by arranging this non-smooth surface 3 of a plurality of raised or sunken formations for multi-direction reflection makes divergence of beam to LED lamp pearly-lustre Shu Jinhang.
In the present embodiment, described non-smooth surface 3 is to arrange the corrugated surface that forms by a plurality of fins, as shown in Figure 1, the fin surface is cambered surface, be evenly distributed after making the light diffuse reflection, simultaneously can be along the long and narrow luminous intensity distribution of fin orientation, when being used for road lighting, be beneficial to light along road length to evenly dispersing and shining on the road surface, be applicable to road lighting and special strip the illumination.
In the present embodiment, the exit facet of described lens body 1 is ellipsoid, according to the law of refraction of light, incident light through ellipsoid refraction back along the ellipsoid face length to dispersing, the uniformity is better, is beneficial to the formation long and narrow area of illumination corresponding with ellipsoid.
In the present embodiment, the fin of described non-smooth surface 3, is beneficial to the light that LED lamp pearl is sent and carries out long and narrow luminous intensity distribution to arrangement along the ellipsoid face length of lens body 1, is applicable to the illumination of road lighting and special strip.
In the present embodiment, described lens body 1 feather edge is provided with fixedly step 4, is convenient to install and fix.
In the present embodiment, the exit facet of described lens body 1 is provided with anti-reflection film, can improve transmittance and light-struck how much utilization rates and light efficiency, reduces intensity of reflected light, avoids light pollution, reduces optical energy loss.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
