The purpose of the invention is to eliminate the defects of known solutions and to implement a device and an application procedure that is capable of adjusting the softness of the emitted light as required.
The inventive step is based on the recognition that, if the flashlight umbrella is implemented according to claim 1 the permeability of the liquid crystal layer can be regulated electronically. This recognition makes it possible to regulate, with the help of the light softening diffuser control electronics, the softness of the emitted light as required using the operating device connected to the light softening diffuser control electronics.
In line with the set objective, the most general implementation form of the solution according to the invention can be implemented according to claim 1. The most general form of the application procedure is described in the main procedural claim. The various implementation forms are described in the sub-claims.
The solution in general is a flashlight umbrella device, which includes a reflector, a light softening diffuser, a stand, a light softening diffuser holding unit, and a light source unit, where the light source unit includes light source control electronics, a luminous body, and reflector holding unit. A distinctive feature of the invention is that the light softening diffuser is fitted with a liquid crystal layer, light softening diffuser control electronics is connected to the electric outlet of the liquid crystal layer through an electric cable, and the light softening diffuser control electronics is connected to an operating device.
In another implementation form, the light softening diffuser is a sheet, advantageously a circular sheet, which is located in a central and perpendicular position to the longitudinal axis of the reflector, and the light source unit also includes a light softening diffuser holding unit.
In another implementation form, the light softening diffuser is a skirt, advantageously a roller skirt, which is placed in a position so that it surrounds the longitudinal axis of the reflector, and the light source unit also includes a light source positioning unit.
In another implementation form, the light source control electronics is connected to the light softening diffuser control electronics, so that it increases the luminance of the light source automatically when the permeability of the light softening diffuser is reduced.
In yet another implementation form, the light softening diffuser is composed of several components, which are connected to the light softening diffuser control electronics through electric cables connected to the individual electric outlet of each component, so that the permeability of each component can be regulated separately.

The presented device has numerous advantages. The sharpness of shadows can be reduced using the light softening diffuser, and it is possible emphasize or dampen the surface texture of objects and persons shown on the image. Unlike earlier, it is unnecessary to replace the light softening diffuser to achieve this effect. It is possible to set the characteristics and scattering of the light as required quickly, possibly using a remote controller. The device may be even connected to a smartphone application, so that its control may be even more comfortable. UV-R and UV-A radiation is emitted when the flashes fire. This 390 to 400 nm light has an impact on the colour quality of the images.
