Description

The invention relates to means of storage, transfer and examination of objects inside a container intended for hand luggage. The proposed device can be used in the manufacture of suitcases, cases, chests, tablets, cases, etc.

A device for viewing objects inside a container is described, described in a.s. USSR No. 1680045, IPC A 45 C 15/00 “Device for storage and transportation of objects”, publ. 09/30/1989 in B.I. No. 36) and comprising a housing, a lid and an optical system in the form of a lens for viewing objects in the housing.

A disadvantage of the known device is that the optical system used in it does not allow viewing objects inside in poor lighting.

Known illuminator for the container described in US patent N4855881, IPC A 45 C 15/06, (NKI 362/156) “Removable illuminator for the container” (Optionally illuminating handle), publ. 08/08/1989

A well-known illuminator for a container comprises a housing, a hinge cover, a light source made in the form of a lamp integrated in the handle, and a lens system directing the light flux into the housing.

A disadvantage of the known illuminator is that it has limited use, namely, only for containers of a certain configuration in which the handle is located in the middle of the lid.

Closer in technical essence and adopted for the prototype is an LED illuminator for a container containing a housing for storing items, a lid, a power source, a voltage regulator and an LED light source located on a surface pivotally connected to the housing.

See, for example, US patent No. 6565228, IPC F 21V 33/00 (NKI 362/154) "Container for storing and displaying objects in it" (Slant container for storing and advertising an article of clothing), publ. 05/20/2003).

The known illuminator has a complex structure, designed primarily for external lighting and its use is justified only for advertising purposes.

The problem solved by this invention is the creation of a simple and reliable light source, as applied to containers, allowing you to consider objects inside the case.

The problem is solved due to the fact that in the known illuminator for a container containing a housing for storing items, a cover pivotally attached to the housing, a power source, a voltage regulator and an LED light source located on a turntable, according to the invention, the platform is made in the form of two racks located on different sides, pivotally connected to the body and each of the racks contains a light source pivotally mounted at its free ends, and LEDs are included in the light sources Ultraviolet and Infrared spectra.

In a variant of the technical solution, one of the racks contains, in addition to the light source, a lens, and the LEDs are placed around the perimeter around the lens.

In an embodiment of the technical solution, visible light sources placed on different sides have a radiation spectrum that differs from one another.

In an embodiment of the technical solution, the light sources are located in a transparent tube fixed between the free ends of the uprights.

In an embodiment of the technical solution, the illuminator LEDs are mounted on boards located on both sides of the tube so that their light fluxes are directed towards each other.

In an embodiment of the technical solution, the illuminator LEDs are arranged along the tube so that their light fluxes coincide with the axis of symmetry of the tube.

In an embodiment of the technical solution, the illuminator LEDs are mounted on a board located along the tube so that their light fluxes are directed across the tube.

In an embodiment of the technical solution, the illuminator LEDs are divided into groups with a radiation spectrum in the infrared, ultraviolet and visible ranges, each group of LEDs receives power through its own switch, and the visible spectrum LEDs receive power from a voltage regulator associated with the light sensor.

In an embodiment of the technical solution, the LED illuminator is equipped with a limit switch.

In an embodiment of the technical solution, two light sources are pivotally attached directly to the lid of the container.

The implementation of the site in the form of two racks located on different sides and pivotally connected to the body, each of which contains a light source pivotally mounted at its free ends, makes it possible to illuminate objects from two sides, which will provide better illumination of the internal cavity of the container. The presence of light-emitting diodes with ultraviolet and infrared radiation spectra makes it possible to discreetly examine objects with the appropriate means (infrared night vision goggles under infrared lighting), read texts written in special ink, and also verify the authenticity of notes (in ultraviolet light) and etc.

The presence of a lens on one of the racks with LEDs placed around the perimeter around the lens will allow you to examine in detail small print or small objects.

The presence on the racks of light sources of the visible range having a different radiation spectrum will allow a better view of volumetric objects.

The implementation of the light sources in the form of a tube fixed between two racks pivotally connected to the housing makes it possible to simplify the design of the illuminator, and it is simple and convenient for the container user to illuminate the inner cavity of the container.

Installing LEDs on the boards on both sides of the tube so that their light fluxes are directed towards each other, provides ease of installation of light sources.

The location of the LEDs along the tube so that their light flux coincides with the axis of symmetry of the tube, provides a more uniform distribution of the light flux.

The location of the illuminator LEDs on the board, along the tube so that their light fluxes are directed across the tube, expands the capabilities of the designer and can be justified when using certain types of LEDs.

The distribution of LEDs into groups with emission spectra, infrared, ultraviolet and visible, in which each group of LEDs receives power from its own switch, allows the user to receive illumination of the internal cavity of the container with the required light source.

The presence of a voltage regulator, working on the signals of the light sensor, makes it possible to ensure uniformity of lighting in the presence of external light sources and to reduce the discharge of the electric power source.

The use of a limit switch allows you to provide automatic mode on and off of the illuminator.

Hinging light sources directly to the container lid simplifies the design of the illuminator.

The multifunctional LED illuminator for the container consists of a housing 1 (Figs. 1, 2, 3), a lid 2 pivotally attached to the housing 1, and struts 3 located on different sides and also pivotally attached to the housing 1. At the free ends of the struts 3 on hinges are installed light sources 4. Hinges (not marked) provide the ability to rotate racks and light sources in two planes. The housing is equipped with an electric power source 5, a control unit 6, containing a light sensor with a voltage regulator 7, and switches 8, 9 and 10. A limit switch 11 is installed in the housing 1, in the place of attachment of the cover 2, 11. The supply wires (not marked) pass through the inside of the racks. The light source is a lantern containing a housing 12 (FIGS. 5, 6), a casing 13 that protects the eyes from direct light, is internally covered with a reflective layer (not shown) and a board 14 with LEDs 15. The shape of the board may differ from round and be e.g. square, rectangular, oval, etc.

In a variant of the technical solution, one of the racks 3 contains, in addition to the light source, a lens 16 (Fig.6, 7), and the LEDs are placed around the perimeter around the lens. The axis of symmetry of the light fluxes of the LEDs 15 are offset so that they intersect at a point that coincides with the focal point of the lens 16. The shape of the lens may differ from round, be oval, rectangular, etc.

In an embodiment of the technical solution, the light source is made in the form of a tube 17 (Fig. 8). As light sources, LEDs 15 are used, located on the boards 18 (Fig. 8, 9) so that the light fluxes from them are directed inside the tube 17.

In an embodiment of the technical solution, the LEDs 15 are located inside the tube 17, along it (Fig. 10) so that their light fluxes are directed parallel to the axis of symmetry of the tube 17.

In an embodiment of the technical solution, the LEDs 15 are mounted on the board 19 (Fig. 11) so that their light fluxes are directed across the symmetry axis of the tube 16, in the direction opposite to the cover. The switches 8-10 can be installed on one of the racks 3 (Fig.12, 13). The tube 16 is equipped with a reflector 20, pivotally mounted on the uprights 3. The light sensor 7 in this case is located separately, as shown in figures 1, 4.

In an embodiment of the technical solution, the light sources 4 (Fig. 14) are pivotally attached directly to the inside of the cover 2.

Electrically, the LEDs 15 are divided according to the radiation spectrum (Fig. 15) into three groups, with radiation spectra, infrared (15r), ultraviolet (15g) and the visible range, for example, white (15w). In addition, the LEDs of the visible range of radiation located on different racks (figure 1), or in different places of the lid (figure 14), or on different sides of the tube (figures 8, 9, 10, 11), have a color of radiation, somewhat different from each other. For example, the 15w LEDs on the left emit a luminous flux with a yellowish tint, and the 15w LEDs on the right emit a reddish tint. These groups of LEDs 15r, 15g, 15w, with different emission spectra are connected in separate circuits. In each individual circuit, the LEDs are connected in parallel. The power supply circuit of the LEDs of each group has its own switch, respectively, for infrared - 8, for ultraviolet - 9 and for the visible range of radiation - 10. The total number of LEDs and LEDs in the group depends on the size of the board (Figs. 4, 5), tube length (Fig. 8, 10, 11) and the intensity of the light emitted by each of them. The switches 8, 9 and 10 are connected to the electric power source 5 through the limit switch 11. In the power supply circuit of the 15w LEDs there is a voltage regulator 7 with a light sensor. The voltage regulator provides for the adjustment of the total illumination. If a battery is used as an electric power source 5, then for its recharging a network adapter 21 can be used, the output voltage of which is consistent with the voltage of the power source 6, and the input voltage with the mains voltage.

Multifunctional LED illuminator operates as follows.

When opening the cover 2, the limit switch 11 is turned on, creating a power circuit for the switches 8, 9, 10 (Fig. 1, 12). The container user has the ability to turn on one or another type of LED, or a combination thereof. So, when the switch 10 is turned on, the visible radiation range of the inner space of the housing 1 is illuminated. By changing the direction of the light flux with the help of articulated light sources (Figs. 1-3), it is possible to provide brighter illumination of one or another part of the interior of the housing. Since the light sources located on both sides have a slightly different color of radiation, the side surfaces of volumetric objects will be highlighted in a slightly different color, which will allow you to better see relief things. External illumination is controlled by a light sensor 7 coupled to a voltage regulator. The higher the ambient light, the lower the supply voltage to the 15w LEDs, and the lower the light intensity emitted by the LEDs. The luminous flux of LEDs directly depends on the magnitude of the supply voltage. The device 7 provides the ability to control the settings of the total luminous flux. When closing the cover 2, the limit switch 11 automatically interrupts the power supply circuit of the light sources.

In the presence of the lens 16 (6, 7), it is possible to consider small fonts or objects placed in the focus of the lens.

The inclusion of a light source with an infrared range (switch 8 and LEDs 15r) is justified in the presence of special means of night vision and allows you to secretly read texts. The use of ultraviolet light (switch 9, LEDs 15g) makes it possible to consider texts written in special (sympathetic) ink, determine the authenticity of notes, etc.

The use of a tubular light source (Fig. 8, 10, 11) provides a simpler layout and greater uniformity of lighting. Various options for the placement of LEDs in the tube expand the capabilities of the designer and depend on the type of lighting fixtures used.

The location of the light sources directly on the lid of the container (Fig. 14) simplifies the design of the illuminator, but limits the user's ability, since it is possible to illuminate the inside of the container only with the lid half open.

Thus, the proposed multifunctional LED illuminator for the container provides high-quality illumination of the internal contents of the container and makes it possible to additionally irradiate texts and objects in the infrared and ultraviolet range, which is necessary for discreet viewing or authentication of documents and banknotes.
