Description

Field of technology

The device for simultaneous illumination of objects from different angles is used for shooting different objects in the field of photography, television and cinematography.

BACKGROUND OF THE INVENTION

A device for simultaneous illumination of objects from different angles [1] is known, which consists of a supporting circular hollow body, to the inner periphery of which many identical internal light sources are established, and to its outer periphery many identical external light sources. The internal and external light sources are located at the same distance from each other. Each indoor and outdoor light source is individually controlled.

The disadvantage of this device for simultaneous illumination of objects from different angles is its limited functionality, which is expressed in the following: there is no universal orientation of the device to the camera or operator, therefore, if the device is rotated at any angle to the camera axis , the angles of the physical sources will not match the logical angles to the camera's view. This implies a delay or inability to quickly change the position of the lighting device, move the view of the camera, or otherwise change the shooting configuration. In addition, the logical control of the lighting has not been resolved, as it is not possible for the lighting operator to be able to control the groups of light sources so that the direction, angle, area, intensity and color can be chosen arbitrarily for each group. . As there is no information on the presence of ambient lighting, when using the lighting device in an environment with already existing ambient light, it is difficult or impossible for the lighting device operator to match the direction, intensity and color of the existing ambient light with the light emitted. from the lighting device.

Technical essence of the invention

The object of the invention is to provide a device for simultaneous illumination of objects from different angles, which has advanced functional possibilities.

This problem is solved by means of a device for simultaneous illumination of objects from different angles, which contains a supporting circular hollow body, to the inner periphery of which a plurality of identical internal light sources are established. A plurality of identical external light sources are provided to the outer periphery of the device for simultaneously illuminating objects from different angles. The internal and external light sources are located at equal distances from each other. According to the invention, more than one light sensor is arranged on the outer periphery of the supporting circular hollow body. An appropriate local microcontroller is mounted inside the supporting circular hollow body and close to each light sensor. A control panel is located towards the outer periphery of the supporting circular hollow body. A central microcontroller and an electronic compass are located inside the supporting circular hollow body. Each of the internal and external light sources can

BG 67317 Bl to be made of any number of light emitting sources of different color. The control panel contains a display, a remote connection module and control elements. Each internal and corresponding external light sources are connected separately to the local microcontroller, to which its corresponding light sensor is connected. The outputs of all local microcontrollers are connected to the central microcontroller connected to a memory block and to an electronic compass. The central microcontroller is also connected to the control panel connected to the remote control module, which is connected wirelessly to a remote control device that has a built-in second control panel.

A variant of the device for simultaneous illumination of objects from different angles is when each of the internal and external light sources also contains a light emitting source with a specific light emitting characteristic.

Another variant of the device for simultaneous illumination of objects from different angles is when the supporting circular hollow body of the device for simultaneous illumination of objects from different angles is composed of at least two sectors interconnected detachably.

An advantage of the invention is the extended functionality, which is that a universal orientation of the device relative to the camera or operator is provided, therefore, if the device is rotated at any angle to the axis of the camera, the angles of the physical sources can correspond to the logical angles to the camera point of view. This allows you to quickly change the position of the lighting device, move the camera's view, or otherwise change the shooting configuration. As the logical control of the lighting is solved, it is possible for the operator of the lighting device to be able to control the groups of light sources, and for each group to be able to choose arbitrarily direction, angle, area, intensity and color. Due to the availability of ambient lighting information, when using the lighting device in an environment with pre-existing ambient light, the operator of the lighting device may match the direction, intensity and color of the pre-existing ambient light with the light emitted by the lighting device. .

In the exemplary embodiment shown in Figure 2, three light emitting sources of different colors 9, 10 and 11. It is possible for each of the internal 2 and external 3 light sources to also contain a light emitting source with a specific light emitting characteristic 12.

The remote connection module 6.2 of the control panel 6 is connected by cable or wirelessly to a remote control device 13, which has a built-in second control panel 13.1. In this embodiment, it is possible for the control panel 6 to be located either on the outer periphery or inside the circular hollow body 1 to ensure the compactness of the device for simultaneously illuminating objects from different angles.

The central microcontroller 7 is also connected to the control panel 6, which is connected to the remote control module 6.2.

Operation of the device according to the invention

The device for simultaneous illumination of objects from different angles works as follows: the operator places the supporting circular hollow body 1 in such a way that the desired subject O is located in the center below the device. The operator presses a button on the control panel 6, which submits a request to the central microcontroller 7 to request information from the light sensors 4. When implementing the device with remote control, the operator uses the second control panel 13.1 on the remote control

BG 67317 Bl management 13 for the submission of the application. Upon receipt of the request, the central microcontroller 7 checks in the connected memory block 14 for a pre-stored viewing angle β concluded between the reference axis of the device C and the observation axis of the camera D.

If there is no stored angle β, the central microcontroller 7 sends to the display 6.1 of the control panel 6 a request to the operator to enter an angle β. When implementing the device with remote control, the same request is sent to the remote control 13. The operator enters an angle of orientation β, which is sent to the central microcontroller 7, where it is stored in memory block 14. The central microcontroller also stores received from the electronic compass 8 azimuth angle a, concluded between the reference axis of the device C and the north direction Ν.

If a stored angle β is detected, the central microcontroller 7 checks for a change in the physical position of the supporting circular hollow body 1 in space relative to the position at the time of storage of the viewing angle of the camera β.

If a discrepancy is found between the current azimuth angle a obtained from the electronic compass 8 and the azimuth angle a stored in memory, the central microcontroller 7 detects a change in the position of the supporting circular hollow body 1 in space and cancels the stored viewing angle β, then requires the introduction of a new viewing angle β by the operator.

When the two angles coincide, the central microcontroller does not detect a change in the supporting circular hollow body 1 in space and continues to give commands to the light sensors 4 requesting data from them.

The central microcontroller 7 calculates the available angles of the light sensors 4 related to the observation angle β and sends the data to the control panel 6, where the display 6.1 shows the sensor reports and their corresponding logical angles to the observation axis of the camera E. of the remote control device, the visualization of the reports is performed on the remote control 13. Thus, the operator receives information about the ambient light, which he uses in his decision to illuminate the subject O located in the center below the device and the objects B located outside the perimeter of the device.

The operator selects a logic source with a desired direction, for example inwards, to the subject O located in the center of the device or outwards to the subject B located outside the perimeter of the device. The operator also selects the beam angle, area, intensity and color of the logic source and dials all these parameters of the control panel 6 through the control elements 6.3. When implementing the device with remote control, the operator dials the parameters of the second control panel 13.1, located on the remote control 13.

The parameters are sent to the main microcontroller 7, which calculates the start and end angles of the logic source based on the beam angle and the area selected by the operator. The start and end angles of the logic source are calculated relative to the viewing angle of the camera β. In this way, the central microcontroller 7 determines the physical locations of a part of the set of identical internal 2 and / or external 3 light sources and determines the connected local microcontrollers 5. The central microcontroller 7 submits the parameters of the determined local

BG 67317 B1 microcontrollers 5, which regulate the voltage of the correspondingly connected plurality of identical internal 2 and / or external 3 light sources and / or their composite sources of different colors 9, 10 and 11.

In this way, the logical source selected by the operator is fulfilled. The operator repeats the process by adding new logic sources until the desired illumination of the subject O located in the center below the device and / or the subjects B located outside the perimeter of the device is achieved.
