Description

The utility model relates to electric light sources, namely electroluminescent light sources, which can be used in everyday life, as well as in industry, in areas where increased high-contrast transmission of color and light images is required, for example, advertising products.

Known from the prior art is the information source DE 102020107668 A1, 09/23/2021, which discloses an information means, in particular business cards or labels, with a front surface that is transparent at least in the areas for providing information, a control means, a light source and an alternating source voltage, a light source having an electroluminescent layer of electroluminescent material that extends above the electroluminescent surface when viewed perpendicular to the front surface, and two electrodes for introducing an electrical change in the field of the electroluminescent material, wherein at least one electrode overlaps the electroluminescent layer only in an overlapping portion electroluminescent layer, when viewed perpendicular to the front surface, wherein the information means is installed in such a way that the alternating voltage source, the electrodes, supply voltage only when the actuator is activated and/or only for a fixed specified time interval after the actuation of the actuator, resulting in the light source emits light onto a partial area of the front surface corresponding to the overlap area.

The main disadvantages of the known technical solution include the excessive flexibility of the lamp (information tool), which makes it difficult to use in everyday life and industry, since it requires an additional surface for placement, which is a limiting factor in widespread use.

In addition, in the known technical solution, the illuminated image is standardized and its size is limited (business card, label), that is, if we talk about the entire surface of the lamp, then at each point it will have a different glow intensity, depending on the immediate distance from the light source .

It is also worth noting that when applying an image to a transparent surface that is illuminated, its contrast is limited to one color; accordingly, against the background of the base color of the lamp, a decrease in the visual sensitivity of the human eye will be observed.

Within the framework of the claimed utility model, contrast is understood as a measure (parameter) of the difference in brightness or color between various elements or objects in a particular system or device. This is a parameter used to evaluate the difference between the lightest and darkest areas of an image, or between different colors.

At the same time, visual sensitivity is understood as the process of perceiving information using vision.

In addition to the above, the technical solution known from the prior art has another significant drawback, namely the lack of illumination over the entire surface of the transmitted color and light information, which negatively affects the contrast and saturation of the transmission of color and light information, which, together with the already known disadvantages of degradation over time, the luminous flux of an electroluminescent lamp negatively affects the uniformity of image illumination.

The prior art contains information source WO 9830069 A1, 07/09/1998, which discloses an elastomeric electroluminescent lamp in which the electroluminescent system, predominantly monolithic, is enclosed in an elastomeric structure. The result is a lamp that is thin, pliable, and membrane-like. The first layer is predominantly applied by screen printing for transfer release paper. The EL system is then applied to the first layer of the shell, again preferably by screen printing, and then a second layer of shell is applied to seal the EL system within the shell. Appropriate windows are cut out or left open to provide electrical contact with the EL system. An optional adhesive layer can then be applied if the lamp is to be used in transfer form for subsequent attachment to the substrate.

A disadvantage of the known technical solution is also its excessive flexibility, which introduces a number of restrictions on the use of this lamp, for example, placement on a table or pendant is not possible for such a solution.

In addition, another important drawback is the lack of protection for the image of an electroluminescent lamp applied to the surface, due to which the image may be subject to mechanical damage during operation, which will negatively affect the light-visual perception of the emitted light.

In addition to the above disadvantages, the known technical solution has a light-information surface, which involves the use of screen printing technology when applying an image to it. This imaging technology has a number of disadvantages.

Colored stencils that are used for this type of printing can fade, lose color and brightness, and since multiple colors require overlaying several stencils of different shades and colors on top of each other, the effect of discoloration of such stencils over time has a negative impact on contrast and saturation color images.

In addition, it is worth noting that at the present time, at the stage of manufacturing electroluminescent lamps, the following technological approaches have become widespread for displaying light-visual information:

screen printing is one of the most common methods of applying color and light information to surfaces, in this case to the surface of a lamp;

transparent and opaque stickers, this technology is based on the use of transparent and opaque stickers, usually made of film of different shades and colors, which contain color information, are applied to a surface, for example a source of light radiation;

colored shells, another way to change the color of the lamp, which uses colored shells. Colored plastic or glass shells can be installed on top of the light fixture, changing the color of the light it emits.

All of these technologies (approaches) have their drawbacks, for example, screen printing has limitations in the detail of a picture or text, especially when using fine lines or small details, in addition, screen printing has a limited selection of colors, depending on the type of stencil and inks used, the choice of colors may be limited, i.e. the images printed in this way have low color saturation, also this process (screen printing) has limited flexibility when changing the design, i.e. once the stencil is created, it is difficult to change or adapt it to other designs .

There are a few things to note about clear stickers:

The use of clear decals has limitations in color accuracy as clear materials may be less accurate in color reproduction, especially on dark surfaces, and colors may appear less saturated due to show-through through the clear material.

In addition to the above features of using transparent stickers, there is also the influence of the background, that is, if a transparent sticker is glued to a surface with different colors or textures, the background can affect the perception of the color and details of the sticker.

Opaque stickers also have their own issues related to hiding the background, that is, opaque materials can hide some or all of the information on the backing, which can be a problem if it is important to preserve the context or color combination with it, in addition, the use of opaque stickers has design limitations , since the use of opaque materials can limit the design, as they can cover part of the surface and interfere with other elements.

The use of colored shells requires the use of an additional housing and many additional fasteners.

The problem solved by the claimed utility model is to create a high-contrast electroluminescent table lamp without the disadvantages of the prior art.

The technical result achieved by the claimed utility model is to increase the contrast of the display of color and light images, the color saturation of the images applied to the surface of the table lamp.

The essence of the claimed utility model lies in the following set of essential features that are in a cause-and-effect relationship with the claimed technical result, namely a table lamp, characterized by the fact that it consists of an opaque electroluminescent light source with contacts for connecting to a source of electricity, on the front surface of which there is an image layer made of full-color printing, a rigid transparent base, to which an electroluminescent light source is attached to the front side by means of a transparent adhesive composition and a stand for placement on the surface.

What is new in the claimed utility model is the absence of an external body of the lamp, the very structural design of the layers of the lamp, ensuring its structural and functional unity, which in essence is the “body”, the frame.

Also new will be the use in the design of an opaque electroluminescent light source, which is the basis for the glow, while it ensures uniform light emission over its entire surface, that is, the light emission of this kind of lamp will be uniform over the entire surface, both in the center and at the edges surface, which makes it possible to increase the contrast of color and light images printed on its front side, compared, for example, with lamps, the light radiation of which differs depending on their location (location of the light source).

In addition, the design on the front part of the electroluminescent light source with the image of a protective coating made by gluing a transparent rigid base onto it provides protection from mechanical damage, for example, scratches.

In this case, protection is provided both to the image applied to the front surface of the electroluminescent light source and to the electroluminescent light source itself.

Also, making an image on the front surface of an opaque electroluminescent light source with full-color printing provides an increase in the color saturation of the image printed on the electroluminescent light source.

Full-color printing is considered to be printing with at least four colors, which, when mixed, will result in a full-color image with a large number of shades.

Such printing, within the framework of the proposed technical solution, provides the following positive effects, namely the use of high-contrast, saturated colors in full-color printing, provides the ability to select bright and expressive colors for the image, which creates a sharper contrast between the various elements of the image and increases color saturation, while ensuring the use of clear boundaries and contours, that is, full-color printing allows you to create clear and defined boundaries between different parts of the image, which helps to increase color saturation.

Color saturation is one of the indicators characterizing print quality.

So in physics, color is determined by the nature of the distribution of radiation in the spectrum of visible light. The most saturated color is formed when there is a peak of radiation at one wavelength, while radiation that is more uniform across the spectrum will be perceived as a less saturated color. In color formation, for example, when mixing paints on paper, a decrease in saturation will be observed when adding white, gray, and black paints.

In color theory - colorist, the saturation of a color, or chromatic tone, is characterized by the visual qualities of clarity and purity, which are achieved by the absence or minimization of admixtures of other tones.

Thus, for example, when combining two colors of the same tone (the white tone of the lamp and the white tone of the external image), the saturation of the white color increases significantly. Equally, this effect can be applied to any color depending on the task, that is, since an electroluminescent light source increases the brightness of the base on which the image is applied, the light passing through it increases the color saturation of the image and the contrast in general.

The structural rigidity of the proposed technical solution is ensured by the use of a rigid transparent base, which can be made of various materials, the main condition for the use of which is transparency and the necessary rigidity; such materials can be used, for example, organic glass, glass, polycarbonate and other materials .

To connect the layers, namely the electroluminescent light source and the rigid transparent base, transparent glue is used, that is, as the non-joining surfaces dry, there should be no visible traces of the adhesive composition.

The above design implementation of the claimed utility model makes it possible to increase the contrast and saturation of the display of color and light images applied to the surface of a table lamp while simultaneously protecting both the image and the electroluminescent light source from damage.

The essence of the claimed utility model is illustrated by drawings.

In fig. 1 shows a general view of the proposed utility model:

1 - electroluminescent light source

2 - contacts of an electroluminescent light source for connecting to an electricity source

3 - image layer

4 - rigid transparent base

5 - stand

6 - layer of transparent adhesive composition.

In fig. Figure 2 shows a view of the inventive lamp (without stand) in working condition, in comparison with a similar lamp in non-working condition.

The production of a table lamp is carried out as follows: an electroluminescent light source is prepared, which is cut out to a given shape and size, that is, the shape of the lamp can be any, for example in the form of a cartoon character, then such a lamp can be used as a night light, depending on this type Such lamps can be widely used in advertising products, alarm systems, etc.

An image layer is applied to the front side of the electroluminescent light source using full-color printing, as the most effective application method, which at the same time increases the saturation of the image.

Next, a transparent adhesive composition is applied to the front side of the electroluminescent light source with the image printed on it, after which a rigid transparent base is applied to it.

At the final stage, the resulting luminous part is attached to the stand.

Contacts from the electroluminescent light source are passed into the stand and connected to the power source.

Since an electroluminescent light source will illuminate the entire surface with a color-light image applied, the contrast of displaying such an image both in light and in darkness will be higher compared to lamps whose design does not use this kind of light emission source, which produces light emission according to the entire surface, while the color saturation also increases, since full-color printing is used, and the emitted light passes through it, so the image on the left lamp, which is in the on state, is more contrasting and saturated compared to the lamp in the off state (Fig. 2 ).

A similar increase in contrast and color saturation is observed in comparison with lamps of the prior art (see above), where there is a difference in brightness across the surface of the lamp, and, consequently, reduced color saturation.

In addition, since the design of the proposed technical solution uses a transparent rigid base on the front side, which can provide a protective function, preventing both the image itself and the electroluminescent light source itself from damage.

Thus, the design of the claimed utility model, a table lamp, makes it possible to increase the contrast of displaying color and light images and the color saturation of images applied to the surface of the table lamp.
