Description

The utility model relates to equipment for underwater photo and video filming and is intended for underwater boxes in which backlighting is used, and improvements to boxes in which there is no such lighting.

A rescue underwater vehicle is known, including a housing, a motion control system located therein, a suction chamber with a support ring mounted on the housing of a rescue underwater vehicle, as well as an auxiliary maneuvering and dynamic positioning system, an outdoor lighting system with lighting elements, optically associated with an optical television outdoor surveillance system and a television information display device. As a suction chamber, a camera is selected, the housing of which includes a movable ball belt, the optical-television outdoor surveillance system is made in the form of a set of television cameras that are installed to provide early warning of an emergency object and are placed on the body of a rescue underwater vehicle around the suction chamber with the ability to observe the support ring with the formation of multi-angle stereopairs, and the outdoor lighting system is equipped with light markers that are installed on the support ring of the suction chamber, etc. This television information display device is automated and is connected via a control motion from the auxiliary maneuvering system and the dynamic positioning system (RF patent for invention №2276647, V63G 8/00, publ. 20.05.2006).

In this device, halogen lamps or LEDs are selected as lighting elements.

The outdoor lighting system is optically coupled to television cameras and includes lighting elements for the lighting necessary to ensure the operation of television cameras that are placed above the support ring, in the particular case, uniformly along its perimeter, which allows you to create the necessary illumination of all television cameras and provide local uniform illumination and visibility in the docking area of the suction chamber.

Lighting elements (lamps) are installed in any known manner, for example, on a bar, with each television camera for early detection of an emergency object can be equipped with an individual

a lamp. Depending on the magnitude of the solid angle of illumination of the television camera, such a lamp can be single, in particular, such as a halogen lamp or LED, or composite, such as, for example, a matrix of LEDs.

Such a lighting system can be used for a set of television cameras, but it is inexpedient to use in camera boxes for underwater shooting, the maneuvering of which is carried out directly by the box user.

Known underwater video camera JJ-CONNECT FISHEYE DELLIX (www.hifivideo.ru), in which 9 white LEDs are used as a backlight. In the known device, the backlight from the LEDs heels directly above the camera body as a separate unit. The camera on the wire falls under the water, and on the monitor screen installed above the surface of the water, you can observe the underwater world, for example, the type of fish that lives in the location of the camera. This underwater camera is designed for anglers.

The limitation of such a camera is to reduce the viewing angle, because the backlight unit is located above its body. Especially the viewing angle decreases vertically (from 83 ° horizontally to 60 ° vertically). In addition, the light source used in the JJ-CONNECT FISHEYE DELUX for illumination cannot be used in standard underwater shooting boxes (for example, CANON), which have buoyancy close to zero. Such a source also cannot be used for standard boxes that are not equipped with light sources at the factory, as well as for any special or independently developed boxes for scuba diving enthusiasts.

Currently, a large number of underwater boxes are produced by various manufacturers (AMPHIBICO, GATES. Hammerhead, IKELITE, LIGHT & MOTION, SEA & SEA, Sony, Subal, TD Housing) (see www.tvzona.ru; www.corvis.ru; www.photodive .ru). Underwater boxes are available for various equipment of manufacturers of video and photo equipment (see, for example, PHENOM FXZ1, VHE S0020 Dive Buddy “EVO”, VX-2000, Vx-950, VX-PC, VX-PC101, VX-PC120, Bluefin HD etc.). In some types of boxes, the surrounding space is not illuminated, but in those of those listed where the illumination is used, the light sources are mounted on brackets attached to the box body or in front of the handles, for which the user holds the box with the camera under water. As light sources use halogen lamps

or a group of LEDs. When placing your own sources on the brackets, the resistance of the box to its movement and maneuvering by the user increases, inconvenience to use occurs, and when placing light sources in the handles, which are naturally placed for convenient maneuvering in the rear of the box, the viewing angle decreases sharply, because the box body itself obscures the luminous flux of the source. There is a need to provide the ability to perform a light source for an underwater box on a quick-detachable nozzle with the maximum possible viewing angle, so that it does not interfere with maneuvering.

The closest is a camera box for underwater photography, containing a housing in which at the end in front of the camera lens a partition is made, transparent and sealed, and two light sources mounted on the housing (Light & Motion Kit, Bluefin FID Pro Package, www.videodive.ru).

In this device, light sources are attached to two flexible brackets mounted on the side of the body, which allows you to change the direction of the light flux from each source. Sources are based on halogen lamps.

The limitations of this device are: the complexity of the design, the need to pre-configure the illumination of the object, the inability to use the design for various types of underwater shooting boxes having various shapes of bodies and overall dimensions, produced by various manufacturers or directly made by underwater shooting enthusiasts.

The task solved by the utility model is the improvement of technical and operational characteristics.

The technical result that can be obtained by performing a utility model is to simplify the design, facilitate use by providing ease of maneuvering the apparatus, increase the speed of shooting by increasing the angle of illumination (view) immediately in front of the subject.

An additional technical result that can be obtained by performing a utility model is the possibility of using boxes of any shape and any overall dimensions.

To solve the problem with the achievement of the specified technical result in the well-known box of the camera for underwater photography, containing a housing in which at the end in front of the camera lens a partition is made, transparent and sealed, and two light sources mounted on the housing, according to the claimed design, at least at least the third light source, the light sources are made of LEDs that are mounted on the end of the housing around the longitudinal axis of the lens, the light sources being fixedly mounted with the emission of light flux along the longitudinal axis of the lens.

Additional embodiments of the utility model are possible, in which it is advisable that:

- a detachable ring was introduced, and light sources are installed on the end of the housing through a detachable ring;

- the number of light sources was selected more than three;

- light sources were located on a circle;

- light sources were located around the perimeter of the square.

These advantages, as well as the features of this utility model are illustrated by the best option for its implementation with reference to the accompanying drawings.

Figure 1 simplified depicts the claimed boxing, a longitudinal section;

Figure 2 is the same, figure 1, an end view of the housing on the LEDs (with the location of the LEDs around the circumference);

Figure 3 - the same, figure 2, (with the location of the LEDs around the perimeter of the square).

The box of the camera for underwater shooting (Figs. 1, 3) contains a housing 1, in which a partition 3 is made at the end in front of the camera lens 2, which is transparent and sealed. Boxing has two light sources 4 mounted on the housing 1.

At least a third light source 4 is introduced into the device. The light sources 4 are made of LEDs that are mounted on the end of the housing 1 around the longitudinal axis of the lens 2. For the light sources 4 opposed to the longitudinal axis of the lens 2, they are located with a transverse dimension L from each other larger than the diameter D of the lens (Fig. 1) . 4 light sources installed

motionlessly with the possibility of emitting light flux by them (shown in Fig. 1 by thin dashed lines) along the longitudinal axis of the lens 2.

A removable ring 5 can be introduced into the device, and light sources 4 are mounted on the end of the housing 1 through a removable ring 5.

The number of light sources 4 can be selected more than three (figure 2, 3).

Light sources 4 can be located around the circumference (figure 2).

Light sources can be located around the perimeter of the square (figure 3).

The claimed boxing works (Figs. 1-3) as follows.

A camera is mounted in its housing 1 so that its lens 2 is located opposite the partition 3. When using a removable ring 5 with LEDs, it is screwed into a “blind” thread made in the end of the housing 1 around the lens 2. In addition, completely different designs of removable rings 5, providing quick disconnect connections, for example, clamping devices, pads, inserts, etc. For boxes manufactured commercially by the industry, devices without a removable ring 5 can be used, in this case light sources 4 — LEDs are directly mounted in the end of the housing 1.

Since the light emitting diodes - light sources 4 are mounted directly on the end face of the outer surface of the housing 1 with the possibility of emitting light flux (the light flux angles are shown by thin dashed lines in Fig. 1) along the direction of the longitudinal axis of the lens 2, the maximum viewing angles and illumination of objects in depending only on the technical characteristics of various types of LEDs. The very location of the LEDs, as shown by experimental studies, has a small effect on the light performance, since a maximum of light is achieved immediately in front of lens 2 and, accordingly, in an object intended for photo or video shooting. Since the light sources 4 are installed with the possibility of emitting light fluxes along the longitudinal axis of the lens 2, an increase in the angle of illumination of the camera is achieved when the light sources 3 are fixed. how

Studies have shown that the claimed device provides an increase in the viewing angle to 88 ° both horizontally and vertically.

For shooting objects located at sufficiently large distances from the camera, the number of LEDs can be significantly increased, for example, up to 8 or more. In addition, for shooting objects located at different distances, removable rings 5 with a different number of LEDs can be used.

Depending on the shape of the end face of the housing 1, light sources 4 can be located around the circumference (Fig. 2), or along the perimeter of the square (Fig. 3) or in any other arbitrary shape: a star, a polygon, etc., since lens 2 can be used any arbitrary shape. In addition, the design does not exclude the location of sources 4 around the lens 2, taking into account the intersection of their light fluxes and ensuring uniform illumination for different distances of the objects from the lens 2 of the camera.

The ends of the LEDs connected to the wires and the wires themselves (not shown in FIGS. 1-3) can be filled with a compound on the outside of the housing 1 to ensure tightness, and, as in the analogs, they will be connected to the battery through a sealed connector.

The most successfully declared boxing camera for underwater shooting is industrially applicable for various designs of boxes manufactured by the industry, in which illumination of objects is not provided. It can also be used in industrially manufactured products that have a backlight, but which require additional backlighting to enhance illumination, or increase the distance of shooting of remote underwater objects, or when underwater shooting of objects located at great depths.
