Example Embodiment

[0015] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

[0016] Such as Figure 1 to 3 As shown, the lens for high-power LED road lighting fixtures of the present invention relates to an LED light source chip, including a lens body. The surface of the lens body includes an arc curved surface and a plane. The center of the arc curved surface is provided with only a symmetry plane, and The lens body is provided with a positioning groove for positioning and installing the LED light source chip on its plane, the positioning groove is adapted to the LED light source chip, and the center of the positioning groove coincides with the center of the lens, and at the same time is in the plane center of the lens body Set long grooves on the light-receiving surface.

[0017] In addition, both ends of the long groove on the light-receiving surface are curved surfaces, and the middle part is a flat surface, so that th...

Abstract

The invention relates to a lens for a high-power LED road lighting lamp. The lens comprises a lens body, wherein the surface of the lens body comprises an arc curve and a plane; a positioning groove for positioning and mounting an LED light-source chip is reserved on the plane of the lens body, and is matched with the LED light-source chip; the center of the positioning groove is superposed with that of the lens; and an illuminated face elongated slot is reserved in the center of the plane of the lens body. The positioning groove for positioning and mounting the LED light-source chip is reserved on the plane of the lens body, and the center of the positioning groove is superposed with that of the lens, so that the LED light source chip can be correctly fixed and positioned in the center of the lens without displacement; and the illuminated face elongated slot is arranged in the center of the plane of the lens, two ends of the illuminated face elongated slot are provided with curve surfaces, and the middle part is a plane. Therefore, illumination angles can be well controlled by regulating the included angle between the curve surfaces at two ends and the plane in the middle.

Description

Technical field [0001] The invention relates to a lens for a high-power LED road lighting lamp, which belongs to the field of lamp manufacturing. Background technique [0002] At present, in the manufacturing industry of high-power LED road lighting lamps and lanterns, the manufacturing of lens for lamps generally has the following shortcomings: (1) There is no light source installation and positioning structure, so the lens is easy to move, and the light source cannot be accurately located at the center of the lens; (2) The center of the lens The internal light-receiving surface has a small curved groove and cannot control the light-emitting angle well; (3) There is no reflective surface on both sides of the lens; therefore, the LED high-power road lighting fixture made of this lens will emit uneven light Light spot, low illuminance, small illumination angle, large dark area between two street lights, etc. Summary of the invention [0003] In view of the shortcomings of the prio...
