DETAILED DESCRIPTION

[0036] In order to make the purpose, technical scheme and beneficial effects of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments.

[0048] In different usage scenarios, different fill light areas and fill light intensities are applicable, which can be achieved by adjusting the fill light device 3.
