Abstract
The utility model discloses a direct downward type light-emitting diode (LED) general lens with length and width of appearance size smaller than 3.5 millimeters. The direct downward type LED general lens comprises a cylindrical bottom and cone frustum upper portion connected on the upper bottom surface of the cylindrical bottom, wherein the lower bottom surface of the cone frustum upper portion coincides with the upper bottom surface of the cylindrical bottom, a conical groove extending into the cylindrical upper portion is arranged in the center of the lower surface of the cylindrical bottom, and a plurality of protrusions are arranged on the lower bottom surface of the cylindrical bottom. The lens can control continuous change of lens design thickness, the curvature, height and the like of the appearance size to achieve curvature change according to the optical grading law, then cause refraction light change to control lighting angles to be expanded according to a lambert mode, and finally achieves the general purpose.
Description
Technical field
The utility model relates to a kind of lens, relates in particular to a kind of appearance and size long and wide all less than 3.5 millimeters general lens of straight-down negative LED.
Background technology
" 3535 " following LED is used for the products such as straight-down negative LED TV, straight-down negative LED illuminating product, automobile LED lamp gradually at present, but " 3535 " the corresponding lens of following straight-down negative LED (LENS) design is widely different, affected by packaged LED overall dimensions and distribution curve flux and emission angle, design custom etc., go back at present the LENS that neither one can be general, design, product, practicality etc. all can not be general.
Summary of the invention
In order to overcome defects, the utility model provides a kind of appearance and size long and wide all less than 3.5 millimeters general lens of straight-down negative LED, these lens are controlled the continuous variation of the appearance and sizes such as LENS Lens Design thickness, curvature and height and are reached the curvature variation according to optics luminous intensity distribution rule, thereby cause that refracted ray changes to control lighting angle and enlarges by lambert's formula, finally reach general purpose.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of appearance and size is long and wide all less than 3.5 millimeters general lens of straight-down negative LED, comprise cylindrical bottom portion and the truncated cone-shaped top that is connected on this cylindrical bottom portion upper bottom surface, and the bottom surface on described truncated cone-shaped top overlaps with the upper bottom surface of described cylindrical bottom portion; Be provided with the cone-shaped groove that extends in the described truncated cone-shaped top at the bottom surface center of described cylindrical bottom portion, on the bottom surface of this cylindrical bottom portion, also be provided with in addition several projections.
As further improvement of the utility model, the side on described truncated cone-shaped top and the curved shape of its upper bottom surface intersection.
As further improvement of the utility model, the diameter≤20mm of described cylindrical bottom portion.
As further improvement of the utility model, the diameter≤4mm of described cone-shaped groove, and the drift angle of this cone-shaped groove≤60 °.
As further improvement of the utility model, the side on described truncated cone-shaped top and the angle of its bottom surface≤40 °.
As further improvement of the utility model, four fixedly suspension columns evenly distribute on the lateral surface of described cylindrical bottom portion.
As further improvement of the utility model, several projections on the bottom surface of described cylindrical bottom portion are tip conical protrusions down, and are the rule distribution.
The beneficial effects of the utility model are: these lens are controlled the continuous variation of the appearance and sizes such as LENS Lens Design thickness, curvature and height and are reached the curvature variation according to optics luminous intensity distribution rule, thereby cause that refracted ray changes to control lighting angle and enlarges by lambert's formula, finally reach general purpose.Simultaneously, the design four fixedly suspension column can guarantee to install stability and symmetry.
