Lighting device

Abstract

A lighting device comprises an luminous body, wherein the luminous body is of a cylindrical structure, is provided with a central shaft and comprises a reflection part and a function part, wherein the reflection part is close to and surrounds the central shaft; the function part is far away from and surrounds the central shaft, and comprises a first shading part; a light guide part and an accommodating part which is adjacent to the light guide part are arranged between the reflection part and the function part, the light guide part is provided with a bright enhancement film which is adjacent to one side of the function part, and the accommodating part is positioned in the limited shading area of the first shading part; a solar cell and a light source are accommodated in the accommodating part, the solar cell is used for receiving the sunlight which passes by the light guide part and the reflection part, and the light from the light source is sent out from the luminous body through the light guide part and the reflection part; and a storage battery is also arranged, is electrically connected with the solar cell and the light source, and is used for storing electric energy which is output by the solar cell and providing electric energy for the light source.

Description

Technical field [0001] The present invention relates to a lighting device, in particular to a lighting device using solar energy to emit light. Background technique [0002] Generally, most outdoor lighting devices use solar energy for energy supply. However, general lighting devices require a large enough solar panel, so they tend to occupy a large volume when installed outdoors. [0003] In addition, the light-receiving area of ​​a general outdoor lighting device almost occupies most of the space of the lighting device, but the light-emitting area is compressed, so it is not enough to meet the needs of outdoor lighting. Summary of the invention [0004] In view of this, a lighting device with a small volume, a compact structure, and a light-receiving area and a light-emitting area are provided. [0005] A lighting device includes a luminous body having a columnar structure and a central axis. The luminous body includes a reflecting part close to and surrounding the central axis; a ...

[0002] Generally, outdoor lighting devices mostly use solar energy for energy supply, however, general lighting devices require sufficiently large solar cell panels, so they often occupy a large volume when installed outdoors

[0003] In addition, the light-receiving area of ​​a general outdoor lighting device almost occupies most of the space of the lighting device, while the light-emitting area is compressed, so it is not enough to meet the needs of outdoor lighting.
