Abstract
An LED lens comprises a lens body. The LED lens is characterized in that the lens body is a solid hemisphere, the upper end face of the lens body is a hemispherical face, the lower end face of the lens body is a plane, a limit ring protruding in the radial direction is arranged on the peripheral edge of the upper end face of the lens body, a circular protrusion is arranged on the lower end face of the lens body, the outer wall of the circular protrusion is provided with a circular limit groove. The LED lens has the advantages that loss of light can be reduced for LED lamps, the light is more condensed and lighting is more effective.
Description
Technical field
The utility model relates to a kind of LED technology, relates in particular to a kind of LED lens.
Background technology
Lens are the strength members in LED lamp, if lens arrangement designs unreasonablely, the light loss of LED lamp is larger, affects illuminating effect.
Utility model content
For the problem in background technology, the utility model proposes a kind of LED lens, comprise lens, its improvement is: described lens are solid hemisphere, and lens upper surface is sphere, and lens lower surface is plane; The peripheral edge of lens upper surface is along the spacing ring that is provided with radial protrusion; Lens lower surface is provided with annular protrusion, on the outer wall of annular protrusion, is provided with annular spacing groove.
Principle of the present utility model is: when use, the illuminating part of LED lamp is arranged in the cylinder groove being formed by annular protrusion, the light overwhelming majority that illuminating part sends can enter in lens, through the refraction action of lens, light is comparatively concentrated, can not disperse, and radiation response is better; Annular protrusion provides installing space for illuminating part except plaing a part, annular spacing groove outside annular protrusion can also be used for the fixing of lens and support: on the support being used in conjunction with the utility model, be provided with corresponding clamping projection, when the annular protrusion of lens inserts after support, clamping projection is just stuck in annular spacing groove, and lens are fixed.
Insert in support for the ease of annular protrusion, the utility model has also been done following improvement: the lateral surface of described annular protrusion lower end is provided with the conical surface.
Rotate for fear of LED lamp, the utility model has also been done following improvement: on the outer peripheral face of described spacing ring, be provided with a square projection.Corresponding installed position is provided with square breach, and after LED lamp is in place, square projection is just stuck in square breach, can prevent that LED lamp from rotating.
Preferably, the height of the land portions of described lens is less than the radius of land portions.
Preferably, the internal diameter of described annular protrusion is 40mm.
Preferably, described lens adopt acrylic material to make.
Useful technique effect of the present utility model is: can reduce the light loss of LED lamp, light is comparatively concentrated, and illuminating effect is better.

Detailed description of the invention
A kind of LED lens, comprise lens 1, and its structure is: described lens 1 are solid hemisphere, and lens 1 upper surface is sphere, and lens 1 lower surface is plane; The peripheral edge of lens 1 upper surface is along the spacing ring 2 that is provided with radial protrusion; Lens 1 lower surface is provided with annular protrusion 3, is provided with annular spacing groove 3-1 on the outer wall of annular protrusion 3.
Further, the lateral surface of described annular protrusion 3 lower ends is provided with conical surface 3-2.
Further, on the outer peripheral face of described spacing ring 2, be provided with a square protruding 2-1.
Further, the height of the land portions of described lens 1 is less than the radius of land portions.
Further, the internal diameter of described annular protrusion 3 is 40mm.
Further, described lens 1 adopt acrylic material to make.
