Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0023] Such as figure 1 , figure 2 As shown, the first aspect of the present invention discloses a polarized lens 1, which is a stretched lens in a long strip shape. It can be observed from the cross-section that the stretched polarizing lens 1 is made by stretching the zigzag cross-section along the length direction. , The characteristics of regular tooth shape. The number of teeth of the polarizing lens 1 disclosed by the present invention is arbitrary, and the tooth shape is not limited. Different tooth shapes and tooth numbers can be produced according to actual needs, so that it can be applied to various requirements in the field of LED lamps, such as wall washers. When the polarizing lens 1 is placed above a row...

Abstract

The invention provides a spreadlight lens used for an LED lamp. The spreadlight lens is arranged at a light emitting port of a light source. The light source is provided with an optical axis. A light inlet of the light source is of a concave structure and is used for reflecting incident light. The spreadlight lens is provided with a light inlet and a light outlet opposite to the light inlet, and the light inlet is of a concave structure and is used for reflecting light rays to the light outlet. The light inlet is further provided with at least two pairs of incident planes and reflection planes which are arranged in an angled mode. The reflection planes are used for reflecting the light rays reflected from the incident planes to the light outlet. The light inlet and the light outlet are two surfaces formed through extension in the length direction perpendicular to the cross section of the spreadlight lens. The invention further provides the LED lamp which comprises a shell, the spreadlight lens and at least two light sources. Each light source is arranged at one side of the light inlet, and the light sources are distributed in the length direction at intervals.

Description

technical field [0001] The invention relates to a polarizing lens for an LED lamp and an LED lamp with the polarizing lens. Background technique [0002] LED wall washer has become an indispensable lighting tool in urban lighting projects. Due to its large lamp body and good heat dissipation effect, and the high-power LED wall washer has an irradiation distance of 1 to 10 meters, it is very suitable for government Panoramic floodlighting for interior and exterior walls of indoor and outdoor places such as lighting projects, commercial places, subways, elevated overpasses, building exterior walls, architectural landmarks, living rooms, entertainment venues, etc. [0003] In practical applications, the lenses equipped with LED wall washers have different shapes according to different needs. The lens modules used in LED wall washers on the market are generally thick and limited to a single structure, and the angle of the outgoing light is limited. Therefore, there is an urgent...
