In one embodiment, referring to fig. 3, the lighting device further includes an outer casing 4 having a light outlet, the lighting module is mounted on the outer casing 4, and the light emitted from the direct-lighting module 3 and the light emitted from the backlight module 5 pass through the light outlet 7 having the microstructure and then exit from the light outlet.

In the embodiment, the outer shell 4 is a cylindrical shell structure with a certain height, the outer contour of the cross section of the cylindrical shell structure can be rectangular, circular or polygonal, and the like, and can be customized according to the requirements of users, so that the user experience can be improved; in addition, the shape of the light outlet of the outer casing 4 may be rectangular, circular, polygonal, etc., and may also be designed according to the requirement.

Therefore, it can be seen that the lighting device simulates a dynamic scene by using the plurality of first LED light sources arranged in an array, simulates direct sunlight by using the direct illumination module 3, simulates a spectrum of sunlight by using an LED packaging technology combined by a plurality of phosphors, simulates periodic changes of sunlight color in different regions, different seasons and different periods of a day by using an algorithm combining longitude and latitude of the earth.

The foregoing is considered as illustrative only of the preferred embodiments of the invention, and is presented merely for purposes of illustration and description of the principles of the invention and is not intended to limit the scope of the invention in any way. Any modifications, equivalents and improvements made within the spirit and principles of the present application and other embodiments of the present application without the exercise of inventive faculty will occur to those skilled in the art and are intended to be included within the scope of the present application.
