Abstract
The utility model relates to an LED optical condensing lens. The LED optical condensing lens comprises a conical lens body, wherein an LED light trough is formed in the small end surface of the conical lens body. The LED optical condensing lens is characterized in that multiple arc-shaped bulges with polygonal bottom surfaces are arranged on the large end surface of the conical lens body, and the bottom surfaces of the adjacent arc-shaped bulges are adjoined with one another. The LED optical condensing lens is simple in structure and good in condensing performance, and the condensing angle of the LED optical condensing lens is approximately 30 degrees.
Description
[technical field]
The utility model relates to a kind of LED optical lens.
[background technology]
The advantages such as light-emitting diode luminous efficiency is high, power consumption is few, long service life are widely used and lighting field, but because its light sending comparatively disperses, therefore all can adopt lens to improve light-gathering.Existing optical lens structure is complicated, and light-gathering is poor.
[utility model content]
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, LED optical concentration lens that light-gathering is good are provided.
In order to address the above problem, the utility model by the following technical solutions:
A kind of LED optical concentration lens, comprise tapered lens body, described tapered lens body, the described little end surface of tapered lens body is provided with LED light trough, it is characterized in that: it is polygonal arc convex that described tapered lens body big end surface is provided with a plurality of bottom surfaces, the bottom surface of adjacent described arc convex adjoins each other.
A kind of LED optical concentration lens as above, is characterized in that: the diapire of described arc convex is hexagon, and described arc convex is covered with whole big end surface.
A kind of LED optical concentration lens as above, is characterized in that: described LED light trough is back taper, the axis of described LED light trough and the dead in line of tapered lens body, and described LED light trough diapire is plane.
A kind of LED optical concentration lens as above, is characterized in that: described tapered lens body is provided with the Elastic buckle upwards vertically extending from described tapered lens body stub end excircle.
A kind of LED optical concentration lens as above, it is characterized in that: described tapered lens body major part one end face is provided with the step cutting pattern that diameter is greater than tapered lens body major part one end diameter, described step cutting pattern is provided with the exiting surface step that diameter is less than step cutting pattern, and described arc convex is located on exiting surface step end face.
The beneficial effects of the utility model have: tapered lens body adopt a plurality of bottom surfaces be polygonal arc convex as exiting surface, the bottom surface of arc convex adjoins each other, its light-gathering is good, optically focused angle is probably in 30 about degree.
