The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0022] refer to Figure 1 , is an exploded view of a lighting device in an embodiment of the present invention. The lighting device of the present invention comprises: a light emitting component 2 and a light guide cover plate 1.

[0023] The light emitting assembly 2 is used to generate light. The light guide cover plate 1 is used to evenly scatter the light. The light emitting assembly 2 and the light guide cover plate 1 are assembled and installed.

[0024] Wherein, the light guide cover plate 1 includes: a light guide portion 11 for guiding out and scattering light and a mounting portion 12 for fixing the light emitting component 2. The light guide portion 11 for guiding out and scattering light is a circular ring structure. The light guide portion 11 is made of a material that can guide light. When light passes through the light guide portion 11, the light is scattered around through the light guide material to achieve the effect of softening the light. The mounting portion 12 for fixing the light emitting component 2 is a circular ring structure. The radius of the light guide portion 11 is greater than the radius of the mounting portion 12. The light guide portion 11 and the mounting portion 12 are fixedly mounted, and the mounting portion 12 is located inside the light guide portion 11.

[0025] The light-emitting component 2 includes: a mainboard 21, a preset number of LED lamp beads 22 and a connector 23. The mainboard 21 is a circular ring structure for installing other components. The middle part of the mainboard 21 is a preset shape set according to demand. The mainboard 21 with a circular ring structure is also conducive to reducing the weight of the light-emitting component 2. At the same time, the middle part of the mainboard 21 with a circular ring structure is left empty, which is conducive to the heat discharge inside the device. The mainboard 21 is installed with a preset number of LED lamp beads 22 and the connector 23. The preset number of LED lamp beads 22 are distributed on the mainboard in the form of a circular array. The connector 23 is installed on the mainboard 21, and the connector 23 is used to connect the circuit so that the circuit can achieve the predetermined function. The mainboard 21 is processed with a preset number of mainboard fixing holes 24.

[0027] The scattering layer 112 is located on the light guide layer 111. The scattering layer 112 and the light guide layer 111 are integrally formed. When the light emitting component 2 is mounted on the light guide cover plate 1, the light guide layer 111 guides the light generated by the light emitting component 2 and guides the light to the scattering layer 112. The scattering layer 112 scatters the guided light to make the light more uniform and softer.

[0028] At the same time, a preset number of heat dissipation holes 113 are provided on the light guide portion 11, and the heat dissipation holes 113 are distributed on the light guide portion 11 in the form of a ring array and are located at the edge of the light guide portion 11. The heat dissipation holes 113 are used to discharge heat inside the lighting device to prevent the high temperature generated inside the device from damaging parts.

[0029] A preset number of cover plate fixing holes 122 are processed on the mounting portion 12. The preset number of cover plate fixing holes 122 are processed on the mounting portion 12 for fixing and installing the light guide cover plate 1. The cover plate fixing holes 122 are used for installing the light emitting assembly 2 on the light guide cover plate 1. The mainboard fixing holes 24 correspond to the positions of the cover plate fixing holes 122.

[0030] When the lighting device described in the embodiment of the present invention is working, first, the light-emitting component 2 converts electrical energy into light energy, so that the LED lamp bead 22 emits light. Then, the light-guiding layer 111 guides the light to the scattering layer 112, and the scattering layer 112 scatters the transmitted light outward. The heat dissipation holes 113 conduct the heat generated by the LED lamp bead 22. Finally, the light-emitting device scatters the light outward with the ring as the starting point, so as to achieve the purpose of uniform lighting.
