Abstract
The utility model provides a lens for an LED lamp. The lens for the LED lamp comprises a lens body which comprises a bottom face and a light outlet face, the bottom face is recessed inwardly to form a groove used for containing LED beads, the wall of the groove is in a shape of an inwardly-concave curved surface, and the light outlet face is in a shape of a convex curved surface. A first cylindrical mounting column and a second cylindrical mounting column are perpendicularly fixed to the bottom face, and the diameter of the first mounting column is larger than that of the second mounting column. The groove wall in the shape of inwardly-concave curved surface forms a light inlet face of the LED beads, and the light outlet face is in the shape of the convex curved surface, so that light given out by the LED beads is subjected to secondary light distribution simultaneously by the light inlet face and the light outlet face, and light outlet efficiency of the LED lamp is effectively improved while illumination of the LED lamp is improved. Further, since the first mounting column and the second mounting column are different in diameter, reverse mounting of the lens can be avoided when the lens is mounted on the LED lamp, accuracy of the lens mounting direction is guaranteed, and assembly efficiency is improved.
Description
Technical field
The utility model relates to the parts of LED light fixture, relates in particular to a kind of lens of the LED of being used for light fixture.
Background technology
The LED light fixture has progressively captured lighting field market because of advantages such as energy-saving and environmental protection.The LED light fixture is according to different application scenarios, and its range of exposures and Illumination Distribution all have different requirement and carry out luminous intensity distribution and handle.Mostly existing lens design is consideration illumination parameter, and has ignored the luminance parameter of actual human eye sense organ, and such design is particularly evident in road lighting, causes bad phenomenon such as zebra effect, lamp are black down.In addition, in practical application, the lens of polarisation can generally use, and when still being installed to lens on the LED light fixture, still through naked eyes identification, the installation effectiveness of lens is very low, even setup error, influences illuminating effect in the differentiation of lens installation direction.
The utility model content
The technical problem that the utility model solves is:
A kind of lens of the LED of being used for light fixture are provided, and these lens not only can improve the illuminating effect of LED lamp, and when being installed to lens on the LED light fixture, can guarantee that the installation direction of lens is correct.
The technical scheme of the utility model is: a kind of lens of the LED of being used for light fixture; Comprise lens body; Said lens body has bottom surface and exiting surface, it is characterized in that, said bottom surface has to cave inward and is formed for holding the groove of LED lamp pearl; The cell wall of this groove is the inner sunken face shape, and said exiting surface is the protrusion curve form; Said bottom surface vertical fixing has columniform first erection column, second erection column, and the diameter of first erection column is greater than the diameter of second erection column.
Said first erection column and said second erection column are positioned at the both sides of said groove.
The end of said first erection column and said second erection column is respectively equipped with chamfering.
The notch place of said groove is provided with and is used for the rectangular opening that the circuit board with LED lamp pearl positions.
The outer wall of said lens body is arranged with two feets.
The beneficial effect of the utility model is: at first; Because the bottom surface has to cave inward and is formed for holding the groove of LED lamp pearl, the cell wall of this groove is the inner sunken face shape, and the groove cell wall that is the inner sunken face shape constitutes the incidence surface of LED lamp pearl; And exiting surface is the protrusion curve form; Therefore the light that sends of LED lamp pearl be simultaneously inner sunken face incidence surface, be the exiting surface that protrudes curved surface and carry out secondary light-distribution, effectively improve the light extraction efficiency of LED light fixture, in conjunction with the complex relationship of brightness and illumination; Make the irradiation area illuminance distribution, improved the illumination of LED light fixture; Secondly, the diameter of first erection column is greater than the diameter of second erection column, because first erection column is different with the diameter of second erection column; When therefore being installed to lens on the LED light fixture, can avoid lens to be adorned instead, guarantee the correctness of the installation direction of lens; Improved efficiency of assembling; The utlity model has simple and reasonablely simultaneously, manufacture easily technique effect easy for installation.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is that the A of Fig. 1 is to sketch map;
Fig. 3 is the schematic perspective view of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Referring to Fig. 1～Fig. 3, a kind of lens that are used for the LED light fixture comprise lens body; Lens body has bottom surface 1 and exiting surface 2; Bottom surface 1 has to cave inward and is formed for holding the groove 3 of LED lamp pearl, and the cell wall of this groove 3 is the inner sunken face shape, and exiting surface 2 is the protrusion curve form; Bottom surface 1 vertical fixing of lens body has the diameter of the diameter of columniform first erection column 4, second erection column, 5, the first erection columns 4 greater than second erection column 5.When being installed to lens on the LED light fixture; First erection column 4, second erection column 5 are inserted into respectively in the different locating hole of two diameters on the LED lamp substrate; Be one-to-one relationship between the diameter of two locating holes and first erection column, second erection column; Be that the first bigger erection column 4 of diameter can only be inserted in the corresponding relatively large locating hole and can not insert in another less relatively locating hole; Thereby the installation direction of guaranteeing lens is unique, has guaranteed that lens beat the correctness of installation direction.First erection column 4 and second erection column 5 are positioned at the both sides of groove, so that the installation of lens.The end of first erection column 4 and second erection column 5 is respectively equipped with chamfering, so that first erection column, second erection column are inserted into respectively in the locating hole on the corresponding LED lamp substrate.The notch place of groove 3 is provided with and is used for the rectangular opening 3 ' that the circuit board with LED lamp pearl positions, so that the location of LED lamp pearl circuit board.The outer wall of lens body is arranged with two feet 6a, 6b, and two feet 6a, 6b are so that the overall fixed of LED light fixture.Lens body is that transparent material is processed, and can make clear glass, also can be transparent plastic, and first erection column, second erection column and lens body are one-body molded.
