Optical structure of LED, LED lamp and device

The invention discloses an LED optical structure, an LED lamp and a device, and the LED optical structure comprises a packaging body which is located on one side of an LED chip light source, wraps an LED chip and is provided with an optical dodging part, and the dodging part is located on a part of light path of the LED chip; the light homogenizing part comprises a concave density structure, the concave density structure is embedded in the surface of the packaging body, and the concave density structure comprises at least one group of light homogenizing surfaces; and dodging spots are arranged on the dodging surface. And when the light rays of the LED chips pass through the light homogenizing surface, the angle of the light rays deviates. The LED light source can effectively solve the problems that in the angle expanding process of an existing LED light source, the light effect loss is large, and the complexity of the manufacturing process of the LED and the rear end is additionally increased. 本发明公开一种LED的光学结构
