Abstract

The invention provides an LED module lens. The lens comprises a lens body and an outer side surrounding one circle of the lower end of the lens body, the bottom of the lens body is concave inwards toform an inner hook face part, the top protrudes outwards to form an outer hook face part, an LED light source is arranged under the inner hook face part, the inner hook face part and the outer hook face part are symmetric in the direction of C0 degree-180 degrees, the inner hook face part and the outer hook face part are in asymmetry in the direction of C90 degrees-270 degrees, the included anglebetween the normal, away from the light condensation face, of the outer hook face part in the direction of C90 degrees-270 degrees and the optical axis of the lens body is larger than or equal to 15.26 degrees, and the light distribution angle of the lens body in the direction of C90 degrees-270 degrees is larger than or equal to 72.02 degrees. The lens can be applied to a street lamp with the outlet light capable of covering eight lanes in the two directions, the outer side is added on the periphery of the lens body, the outer side is used for mounting of the lens, the outer side is designedto the regular graph, mounting and seal of the lens are facilitated, and periphery mounting stress uniformity of the lens is ensured.

Description

Technical field [0001] The present invention relates to the technical field of lighting devices, in particular to an LED module lens. Background technique [0002] The lens is an indispensable electrical component in the LED module, and it can be closely linked with the LED light source to enhance the light use efficiency and luminous efficiency. [0003] The lens in the existing LED module has the following problems: 1. It cannot meet the use of roads with more than six lanes in two directions; 2. Because the structure of the existing lens is irregular, it is inconvenient to install and seal around it. Summary of the invention [0004] In order to solve the problem in the background art, the present invention provides an LED module lens, which includes a lens body and an outer edge surrounding a circle at the lower end of the lens body; the bottom of the lens body is concave to form an inner curved portion and a top The convex forms an outer curved portion, and the LED light sourc...
