Abstract
The utility model discloses an LED lamp bead optical mixing lens structure, which comprises a transparent body and an LED lamp bead, wherein the transparent body is a shell with an inner cavity, the shell is in a trumpet shape which is expanded gradually from the bottom to the upper portion, a spherical cap convexly extends out from the middle portion on the upper end surface, the lateral face is an outward convex arc shaped transition surface and is provided with reflecting materials, holes are matched on the lower end surface of the transparent body, and the LED lamp bead extends into an inner cavity of the shell. The LED lamp bead extends into the inner cavity of the transparent body due to the arrangement of a special shape of the transparent body, light which is emitted to the surroundings from a point light source of the LED lamp bead can be converged through the arc-shaped transition surface with the reflecting materials and is irradiated outwards through the upper end surface, the light of the LED lamp bead can form a light beam and can be effectively irradiated to an appointed area, the spherical cap which is convexly arranged on the upper end surface has the reflected distributing function to the light which is positively opposite to the position of the LED lamp bead for distributing the light beam to the areas which need irradiating evenly, and the emitted light beam can be even and soft.
Description
Technical field
The utility model belongs to the Application Optics field, particularly a kind of LED lamp pearl secondary mixing optical lens structure that is applied to throw light on.
Background technology
Development trend along with energy-saving and emission-reduction, LED (Light Emitting Diodes, light emitting diode) with characteristics such as its energy-conserving and environment-protective, luminous efficiency height, life-span length, obtain application more and more widely, LED is as a kind of novel solid light source, aspect the city illumination light source, the trend that replaces the conventional road lamp light source is arranged greatly.Yet the luminous of LED street lamp is to be combined by single LED lamp pearl, because very little, the approximate spot light of the light-emitting area of each LED lamp pearl, short distance has only the brightness of some places very high, other direction is but very dim, and light is inhomogeneous, and brightness centrostigma place is comparatively dazzling; And the spot light characteristics of LED pipe, its light penetrate be to around scattering, not only loss light, and irradiation distance is limited, in addition secondary optics design can make light to the effective coverage cover, just can satisfy lighting requirement.
The utility model content
The purpose of this utility model provides a kind of LED lamp pearl mixed light lens arrangement, and it can realize the uniformly light-emitting of LED lamp pearl, and can make light shine to reach specific lighting requirement in effective zone.
For reaching above-mentioned purpose, solution of the present utility model is:
A kind of LED lamp pearl mixed light lens arrangement comprises the transparent body and LED lamp pearl; This transparent body is one to have the housing of inner chamber, and this housing upwards is the horn-like of flaring from the bottom, and the middle part of its upper surface protrudes out a spherical crown; And the side is the arc transiting surface of evagination and is provided with reflectorized material; Mating holes on the lower surface of this transparent body, pearl stretches in the housing inner chamber LED lamp.
Described reflectorized material is that reflective membrane is coated on the side outer surface.
Described upper surface and lower surface are rectangle, and the quadrangle of upper surface becomes the inverted arc angle.
Protrude out an oval spherical crown on the described upper surface.
Described upper surface and lower surface are circle or polygon.
Be fixed with a link under the described lower surface, the both sides of this link have protruded out card base downwards.
The described transparent body is injection molded by PMMA.
The described transparent body blows casting by transparent material and forms.
Described transparent material is a glass.
After adopting such scheme, the utility model is by the setting of this transparent body special shape, and LED lamp pearl is to stretch the inner chamber that places this transparent body, LED lamp pearl spot light can be converged by the arc-shaped transition side that reflectorized material is arranged to the light of emission all around, to external exposure, make the light of LED lamp pearl form light beam via the upper surface to the effectively irradiation of the zone of appointment; And the spherical crown that is convexly equipped with on the upper surface has the effect that a refraction distributes to the light over against LED lamp pearl position, light beam is distributed to equably the zone that needs irradiation, makes the light beam that sends even, soft.
Description of drawings
Fig. 1 is a schematic perspective view of the present utility model;
Fig. 2 is a front view of the present utility model;
Fig. 3 is a side view of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment the utility model is elaborated.
As shown in Figure 1, 2, 3, LED lamp pearl mixed light lens arrangement of the present utility model comprises the transparent body 1 and LED lamp pearl 2.
This transparent body 1 is one to have the housing of inner chamber 11, this housing upwards is the horn-like of flaring from the bottom, its upper surface 12 forms the rectangle end face, the quadrangle of this upper surface 12 becomes the inverted arc angle, on upper surface 12, convex with a spherical crown 121, this spherical crown 121 cooperates the length limit of rectangle end face and forms oval spherical crown, and the lower surface 13 of this transparent body 1 also is a rectangle end face, has mating holes 14 on this lower surface 13 to stretch in the housing inner chamber 11 for LED lamp pearl 2; And four sides 15 of this transparent body 1 are the arc transiting surface of evagination, and each side 15 outer surface is provided with reflectorized material, as are coated with reflective membrane.
Certainly, the upper surface 12 and the lower surface 13 of this transparent body 1 not only are confined to the rectangle end face, and it also can be the end face of circle, polygon or other shape.
Be fixed with a link 3 for 13 times in the lower surface of the transparent body 1 in addition, the both sides of this link 3 have protruded out card base 31 downwards, so that be connected and fixed with the supporter (not shown).This transparent body 1 can be by the injection moulding of PMMA (methyl methacrylate) optical material, and perhaps other transparent materials (for example glass) blow to cast and form.
Setting just because of this transparent body 1 special shape, and LED lamp pearl 2 is to stretch the inner chamber 11 that places this transparent body 1, LED lamp pearl 2 spot lights can be converged by the arc-shaped transition side 15 that is coated with reflective membrane to the light of emission all around, to external exposure, make the light of LED lamp pearl 2 form light beam via upper surface 12 to the effectively irradiation of the zone of appointment; And 121 pairs of light over against LED lamp pearl 2 positions of the spherical crown that is convexly equipped with on the upper surface 12 have the effect that a refraction distributes, and light beam is distributed to equably the zone that needs irradiation, make the light beam that sends even, soft.
To sum up, the utility model utilizes the arcuate flanks 15 of this transparent body 1 can have the function that a reflection is converged to the light of LED lamp pearl 2 just, utilize 121 pairs of light of spherical crown of upper surface 12 to carry out mixed light, reach with this and to make light that LED lamp pearl 2 sends, improve the light efficiency of LED lamp pearl 2 to the effective coverage cover.To make LED lamp pearl 2 go for widely in the illuminator.
