Abstract
The utility model relates to an LED (light-emitting diode) lens which comprises a lens body, wherein a cylindrical groove for assembling an LED light source is arranged at the bottom surface of the lens body; a light inlet surface is formed at an inner cylindrical surface of the cylindrical groove; a total reflection light surface is formed at the lateral surface of the lens body; a light outlet surface is formed at the top surface of the lens body; and a wavy stripe used for changing the refraction direction of emitted light is arranged at the top surface of the lens body. The LED lens performs secondary optical distribution for the LED light source, the wavy stripe is arranged at the top surface of the lens body, so that the emitted light by an LED is refracted to a receiving surface in a deviation way through the wavy stripe; therefore, the illumination efficiency is greatly improved, the energy is saved, the light pollution is reduced, the environment is beautified, light is sufficiently mixed in the landscape illumination, and chromatic aberration is unavailable.
Description
Technical field
The utility model belongs to the LED lighting field, specifically is meant a kind of LED lens.
Background technology
More and more near people's life, the Landscape Lighting in a lot of cities though highlighted the splendid of light and color, has been wasted electric energy owing to pay attention to lighting engineering simply, has also caused serious light pollution in the LED illumination.Light pollution can cause people's giddy vexed, depressed and health is weak, and have a strong impact on sleep quality especially artificial daytime, causes the biological clock disorder, causes pathology easily.According to international standard, the normal bright illumination mean value in city should be 15 lumens, and is just not unhealthful, and after tested, light illumination the highest 1000 lumens that surpass in part downtown exceed standard more than 60 times than normal value.
Therefore, be necessary to carry out the secondary optics luminous intensity distribution at led light source, wherein a kind of is symmetrical luminous intensity distribution, and the outgoing hot spot of LED is a circular light spot, and emergent light is when shining light-emitting area, and about 50% light scattering has formed light pollution to sky; Also have a kind of asymmetric luminous intensity distribution that is, the lens of existing asymmetric luminous intensity distribution mostly are irregular free form surface, with the symmetrical luminous intensity distribution of routine obvious architectural difference are arranged, and are inconvenient to produce utilization; Also there are the part lens to adopt microprism refraction Pattern Design, but all do not consider the influence of light pollution, the serious deficiency that exists.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of emergent light deflection that makes and shines the face of acceptance, improves the LED lens of illumination efficiency, minimizing light pollution.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of LED lens, comprise lens body, be provided with the cylindrical grooves that led light source is installed in the bottom surface of lens body, the inner cylinder of cylindrical grooves forms incidence surface, the side of lens body forms the total reflection light face, the end face of lens body forms exiting surface, and the end face of described lens body is provided with the wavy striped that is used to change the emergent light refractive direction.
Each striped all has than gently sloping surface and than sty in the above-mentioned wavy striped, and wavy striped is inwardly arranged in pairs by exiting surface two symmetrical edges respectively, each striped than equal self the formation outside outward of gently sloping surface; One independent wavy striped is set to the exiting surface center, over against LED top go out the luminous point place be wavy striped than gently sloping surface.
It is that both sides, center angle is the hot spot within 20 ° with the led light source that the size of above-mentioned cylindrical grooves satisfies light emergent light formation after the groove inner cylinder is assembled that led light source is sent.
The utlity model has following remarkable result:
The utility model LED lens carry out the secondary optics luminous intensity distribution with led light source, by end face wavy striped is set in lens body, make the emergent light of LED be refracted to the face of acceptance by wavy striped deflection, thereby improve illumination efficiency greatly, energy savings reduces light pollution, beautifies the environment, and in Landscape Lighting abundant mixed light, no color differnece.
Description of drawings
The specific embodiment
For the ease of it will be appreciated by those skilled in the art that the utility model is explained in further detail below in conjunction with accompanying drawing and embodiment.
Shown in accompanying drawing 1～3, a kind of LED lens, comprise lens body 1, lens body 1 is horn-like, be provided with a cylinder shape groove 2 in the bottom surface of lens body 1, led light source is installed in the cylinder shape groove 2, and the inner cylinder of cylinder shape groove 2 forms incidence surface, incidence surface comprises side incident face 21 that is positioned at cylinder shape groove 2 cylindrical sides and the end face incidence surface 22 that is positioned at cylinder shape groove 2 cylinder end faces, and LED illumination is at first shone on side incident face 21 and end face incidence surface 22; The side of lens body 1 forms total reflection light face 11, and the end face of lens body 1 forms exiting surface.Light is penetrated on total reflection light face 11 from incidence surface incident lens body 1, and light reflexes to exiting surface from total reflection light face 11 again and penetrates.
Present embodiment LED lens are provided with wavy striped 3 at the end face of lens body 1, and wavy striped 3 is near symmetrical and distributes.In fact, each striped all has than gently sloping surface 31 and than sty 32 in the wavy striped 3, and wavy striped 3 is respectively by the inside symmetric arrays in pairs in exiting surface two symmetrical edges, each striped than equal self the formation outside outward of gently sloping surface 31; But when arranging, an independent wavy striped 3 is set to the exiting surface center, over against led light source top go out the luminous point place be wavy striped 3 than gently sloping surface 31.
When led light source light reflexed on the exiting surface from total reflection light face 11, light reflected by wavy striped 3, and the emergent light deflection of LED is refracted to the face of acceptance one side.
The light that sends in the middle of the LED light source in the present embodiment is understood coalescence through end face incidence surface 22 and is distributed within angle ± 20 °, other whole 180 ° light that send from LED carry out luminous intensity distribution through the total reflection light face 11 that side incident face 21 is transmitted into, and wavy striped 3 makes the emergent light deflection of led light source be refracted to the face of acceptance one side.Suitable and make the outgoing anaclasis for the emergent light refraction angle that makes LED to required direction, according to the law of refraction formula n of light
'SinI
'=nsinI, wherein n
'Be the refractive index of lens body 1 material, I
'Be incidence angle, n is an air refraction, and I is the refraction angle, because the absolute index of refraction of air is 1.00028, think that in approximate calculation air is identical with vacuum, thereby can calculate the refraction angle of bright dipping, so determine wavy striped 3 than gently sloping surface 31 with than the radian or the gradient of sty 32.
The foregoing description only is a preferred implementation of the present utility model, and in addition, the utility model can also have other implementations.That is to say that under the prerequisite that does not break away from the present utility model design, any conspicuous replacement all should fall within the protection domain of the present utility model.
