Abstract
The utility model relates to a condenser lens who has high -efficient spotlight function, this condenser lens are with light axisymmetric round platform form lens, and the less inside sunken holding chamber that forms in first terminal surface middle part of diameter, this holding chamber are for the holding light source, and the bottom surface in holding chamber outwards protrusion forms first sphere, the great second terminal surface of diameter inwards caves in and forms a cavity, and the bottom surface of cavity is outwards bulgeed and is formed the second sphere, the lateral wall of lens is the complete reflective surface. Having efficient spotlight effect, making the light that reflects be close parallel with the axis more, higher light passes through the utilization ratio.
Description
Technical field
The utility model belongs to optical technical field, particularly relates to a kind of collector lens with high-effective concentration function.
Background technology
In order to reach the spotlight effect to light source, common way adopts exactly has paraboloidal light gathering reflector cup, and this reflector is difficult to be used in the little light source of light emitting anger; Occur adopting convex lens to carry out optically focused to light source in prior art, current collector lens the full collector lens of really, just reflection from lens face portion optically focused, reflecting surface is normally rotated by parabola or hyperbola and forms, because first reflecting surface can be refracted to when light source enters lens by air, each angle all has deviation, therefore cause can not real full optically focused, and a part of light is then as floodlight in addition.
Utility model content
The purpose of this utility model is to provide a kind of collector lens, and it has efficient light-focusing function and higher light passes through utilization rate.
For achieving the above object, the utility model is achieved through the following technical solutions.
There is provided a kind of collector lens, this collector lens is with the axisymmetric round table-like lens of light, and the first end Middle face that diameter is less caves inward formation one accommodating cavity, this accommodating cavity in order to accommodating light source, the outwardly formation first in the bottom surface sphere of accommodating cavity; The second end face that diameter is larger caves inward the outwardly formation second in the bottom surface sphere of formation one cavity, cavity; The sidewall of described lens is fully reflecting surface.
Above-described technical scheme, further, the radius of the first described sphere is equal with the radius of the second sphere.
Above-described technical scheme, further, the side of described accommodating cavity is the face of cylinder, and the basal diameter of accommodating cavity is slightly less than its opening diameter on the first end face.
Above-described technical scheme, further, the side of described cavity is the face of cylinder, and the basal diameter of cavity is slightly less than its opening diameter on the second end face.
Above-described technical scheme, further, described fully reflecting surface to be rotated around optical axis by the parabola of more than at least two sections to be formed.
The technical solution of the utility model, its technique effect is, has efficient spotlight effect, and make the light reflected more close to parallel with axis, higher light passes through utilization rate.

Fig. 1 is the cross section view of the collector lens in embodiment.
Fig. 2 is the front view of the collector lens in embodiment.
Fig. 3 is the light concentrating light principles view of the collector lens in embodiment.
Detailed description of the invention
Elaborate below to conjunction accompanying drawing and specific embodiment to the technical solution of the utility model.
As shown in Figure 1, the collector lens of the present embodiment is with the axisymmetric round table-like lens of light, the sidewall of lens is fully reflecting surface 1, fully reflecting surface can be regarded as and formed around middle shaft rotation by curve, curve is made up of N section parabola, the constant that N is greater than 2, N value is larger, and the light reflected is more close to parallel with axis; All focus is corrected to every section of parabola, the light that LED is sent by reflective surface go out only parallel with axis, light is as shown in Figure 3.
Cave inward in the middle part of the first end face 2 that collector lens diameter is less formation one accommodating cavity 3, this accommodating cavity in order to accommodating light source 4, the outwardly formation first in the bottom surface sphere 5 of accommodating cavity; The second end face 6 that diameter is larger caves inward the outwardly formation second in the bottom surface sphere 8 of formation one cavity 7, cavity; First sphere and the second sphere form convex lens, and the radius of first end sphere is equal with the radius of the second end face, and the parallel light axis injection that LED light source sends by convex lens, light as shown in Figure 3.
As shown in Figure 1, 2, the side of accommodating cavity is the face of cylinder, and the basal diameter of accommodating cavity is slightly less than its opening diameter on the first end face.The side of cavity is the face of cylinder, and the footpath, footpath, bottom surface of cavity is slightly less than its opening diameter on the second end face.
The light part that lens total reflection operation principle: LED sends is hidden after the sidewall refraction of position through LED and is reflected into the light parallel with axis through fully reflecting surface, and light another part that LED sends is penetrated by convex lens parallel middle axes, thus makes lens reach full optically focused.
