Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a local lighting mechanism 20 of general illumination, includes lamp shade support 6, and aluminum alloy face lid 5 is fixed and is formed the shell at 6 surperficial formation of lamp shade support, and lamp shade 11 is installed on lamp shade support, forms the lighting mechanism body, and lighting mechanism passes through connecting device 30 and the lamp pole fixed connection of desk lamp, and the structure of desk lamp is not detailed here again, the utility model discloses a lighting mechanism mountable is on the desk lamp of different models. A plurality of PCBA lamp panels used for emitting light are fixedly arranged on the lampshade support 6, the first PCBA lamp panel 4 emits light downwards to form a first light emitting layer, the second PCBA lamp panel 7 emits light upwards, and a light source emitted by the second PCBA lamp panel 7 is formed by reflecting a medium, and the second light emitting layer covers the first light emitting layer downwards.

Each PCBA lamp plate is provided with a lens and a fixed cover, a first lens 3 is laminated on the light emitting surface of the first PCBA lamp plate 4, the first fixed cover 2 is fixed, a second lens 8 is laminated on the light emitting surface of the second PCBA lamp plate 4, and the second fixed cover 10 is fixed.

First lens pass through the screw and fix simultaneously with the laminating of first PCBA lamp plate 4 in the inside light of sending the lamp pearl above 4 of the back of lamp shade support 6 and carry out the processing for the first time.

First PCBA lamp plate 4 passes through the screw and fixes simultaneously inside the back of lamp shade support 6 with the laminating of first lens 3, and the connecting wire of 7 through the second PCBA lamp plate is rather than being connected the power supply. Diffuser plate 1 assembles on first lens 3, fixes it through first fixed cover 2, and first fixed cover 2 plays fixed diffuser plate 1's effect through the knot position assembly of self at the back of lamp shade support 6, and first PCBA lamp plate 4 is luminous to change the angle optimization processing of light through first lens 3, and light can be increased diffuse reflection once more when light sees through diffuser plate 1 and make the gentle comfortable optimization of light.
