Description

Technical field

This invention relates to lighting, in particular to light sources, both stationary and portable.

State of the art

At present, decorative lamps based on both traditional light sources and LEDs are very diverse in their external design, but their aesthetic and emotional effects on humans are not always taken into account. Often they are not very attractive. The exceptions are instances made as works of art.

A significant improvement in the parameters of light-emitting diodes, observed recently, allowed us to begin to realize their advantages in those areas in which it was previously limited by their low lighting characteristics. In recent years, serial production of high-performance LEDs of all primary colors, consuming low power, having an efficiency higher than that of incandescent lamps, and a significant service life of up to 100,000 hours has been established. A series of luminaires and lamps are currently being created and produced on their basis. (see, for example, US patent No. 6257737 [1], international application WO 01/24583 [2]). In accordance with [1], white light is created by static mixing of red, green and blue (blue) radiation of LEDs. In this case, the mixing should be precise and homogeneous not only in spectrum and power, but also in space.

A decorative lamp is known, including a glass sheath, at least two LEDs of different colors located inside the sheath, and a base installed at the base of the lamp, containing an electrode system for connecting the lamp to an electrical power supply on one side and LEDs on the other. At the same time, the LED heads are made so that their radiation propagates in all directions except the base (see patent

EP 0822371, [3]). Its disadvantages include the lack of a range of color effects, which leads to its lack of attractiveness.

Obviously, they leave the best impression and correspondingly more attractive lamps with a time-varying color of the glow, which are thus much more decorative.

The closest to the present invention is a decorative multi-color lamp (see international application WO 01/41514 [4]). The radiation source of the said luminaire consists of three-color LEDs localized in three single-color groups, and a control circuit with a controller. The groups are placed on the board and the glow of each one-color group of LEDs is spatially separated. Power is supplied through a control circuit with a controller that contains programmed channels for separately controlling the emission of LEDs of each color, i.e. for separate management of monochrome groups.

The radiation source is mounted on a flat base, with a board with three groups of single-color LEDs on one side and a control circuit with a controller on the other side. The diffuser through which the radiation of the LEDs passes is fixed in the walls of the housing, which in turn is fixed on the base, from the location of the LEDs. The power terminals of the control circuit are located and mounted outside the diffuser. The diffuser is a transparent plate with a corrugated surface to obtain a more uniform and aesthetic glow of the LEDs of each one-color group. In the known luminaire under consideration [4], the LEDs of different colors are connected in series, and their radiation is not mixed due to the existing design solution. Such a lamp [4] does not produce a strong emotional effect, it is not aesthetically pleasing and attractive.

Disclosure of invention

The technical result of the present invention is to increase the attractiveness of a decorative multi-color lamp, efficiency, reliability, expand its functionality and add new consumer properties, simplify its operation.

The technical result is achieved by the fact that the decorative multi-color lamp, comprising a radiation source containing at least two

LEDs of different colors with a given spatial distribution of radiation, placed with a given spatial localization, a board and a control device containing programmed channels for separately controlling the emission of LEDs of each color, as well as including a diffuser, a base and electrical leads, and LEDs of different colors are spatially localized at least in one group, the diffuser is made of at least three parts, two of which are external and internal reflective frames, with extensions directed in the same direction, and on the opposite side mounted on the base at a distance between them, necessary to place at least one board with LEDs, the third part of the diffuser, mainly transmitting, is installed in the output aperture at least one of the reflectors, in addition, at least one board with LEDs is placed inside the internal reflector and each part of the diffuser is made partially surrounding the radiation propagation region at least Here are some of the LEDs of the radiation source.

The difference of the proposed decorative multi-color lamp (hereinafter referred to as the "Lamp") is the original combination of essential distinguishing features, which consists in the novelty of the arrangement of the elements, their interconnections, the materials from which the elements are made. The choice of such a combination allows the manufacture of Lamps for various purposes, highly reliable, much better aesthetic and emotional perception, economical, new, uncomplicated in design, fairly cheap and technologically reproducible using known means. Note that further LEDs of different colors of the same group will be called a "cluster".

Various modifications of the Lamp are proposed, due to the different mutual arrangement of its elements, allowing to obtain a variety of lighting effects, improved perception of the Lamps.

The technical result is achieved in that the third part is installed in the output aperture of the internal diffuser-reflector, and in the output aperture of the external diffuser-reflector, limited by the output aperture of the internal diffuser-reflector, an additional fourth part of the diffuser is installed, which is transmission.

In another modification, the technical result is achieved by the fact that the third part is installed in the output aperture of the internal diffuser-reflector.

In the following modification, the technical result is achieved in that the third part is installed in the output aperture of the external diffuser-reflector, including when the aperture of the external diffuser-reflector is limited by the aperture of the internal diffuser-reflector.

Various modifications of the Lamp are possible, which leads to a different number of elements considered.

So, for example, the technical result is achieved by the fact that

- the proposed Lamp is equipped with at least one radiation source,

- the radiation source is additionally equipped with at least one control device,

- the radiation source is additionally equipped with at least one board predetermined relative to the existing board depending on the configuration and number of clusters, LEDs in the cluster, the number of control devices and their location, etc.,

- the cluster (s) and / or control device (s) can be located (s) on the board (s),

- the control device (s) can be located on the board (gut) and the board can be placed inside the diffuser or outside the diffuser, (the location outside the diffuser also allows simplifying the operation of the Luminaire - the control unit is easier to maintain and change),

- all control devices are located on the same board,

- each control device is located on its corresponding board,

- the base can be either monolithic or composite.

- the board or boards located inside the diffuser may be located (s) both on the base and directly on the inside of the diffuser, or in some other way fixed (s) inside the diffuser,

The mutual arrangement of available and additional elements depends on the specific design of the Lamp in connection with its purpose. At the same time, a greater variety of colors is achieved, increasing the attractiveness of the Lamp, as well as increasing its effectiveness.

The technical result is achieved in that each part of the diffuser is either scattering, or refracting, or simultaneously scattering and refracting.

To obtain the mentioned combinations of optical characteristics, the proposed scatterers can be made of various materials, can have different coatings, surface conditions, internal properties of the walls of the scatterers, or they can be made in a certain constructive way. As a result, optimization of the claimed technical result is achieved.

So, for example, modifications are proposed for which the technical result is achieved by the fact that

- the inner surfaces of the diffuser-reflectors and / or the outer surface of the internal diffuser-reflector are not only predominantly reflective, allowing to obtain the most powerful effect of the Lamp, but also / or diffusely reflective, in particular matted, to obtain a softer and more even radiation.

- for the third and / or fourth parts of the diffuser, the material can be, for example, either milk-colored glass, or plastic, at least partially transparent, including milk-colored, or some other material that is simultaneously refractive and diffusing, or faceted glass, or faceted crystal, which are more refractive. Also, the third and / or fourth parts of the diffuser can be made in the form of a transparent film, including a polarizing interfering film. Moreover, the said parts of the diffuser can be made in the form of plates, films, lenses, can be convex, concave, or have any other arbitrary configurations.

The mixing of the light emitting diodes of different colors in the Lamp occurs in the internal volume of the diffuser, on its surfaces and inside its walls.

The proposed Lamps are very spectacular, aesthetic.

In addition, the technical result is achieved in that the diffuser-reflectors can be made in the form of a dome, a bowl open on one side of the box, a cube, etc., output cross sections - their output apertures can be a circle, ellipse, letter, digit, or have some other arbitrary shape.

For any proposed modification of the Lamp, the technical result is achieved by the fact that at least its radiation source and electrical leads are sealed.

Such a Luminaire can be used either in conditions of potentially high humidity, for example, for landscape lighting, or for example, in various floating and water-immersed objects, such as toys, balls, boats, boats, fish, which can also serve as original advertising media, i.e. . expanded functionality and added new consumer properties of the Lamp.

For all the proposed modifications, in order to achieve a technical result, various arrangements of LEDs and groups of LEDs are proposed, for example,

- the axis of emission of the LEDs is predominantly perpendicular to the inner surface of the corresponding diffuser (in this case, the efficiency of the Luminaire increases), the light fluxes of the LEDs are mainly uniformly distributed over the surface of the diffuser.

- There are at least two groups of LEDs that irradiate different areas of the diffuser.

The technical result is also achieved by the fact that the shape of the base can be different, for example, flat, convex, concave, convex-concave, flat circle, polygon, etc., or some other shape corresponding to the required modification of the Lamp, the distribution of LEDs, groups of LEDs on the surfaces of the base to obtain a given distribution of light fluxes on the inner surface of the diffuser.

The proposed various arrangements of LEDs and their groups also allow you to expand the functionality and add new consumer properties of the Lamp, improve aesthetic and emotional perception, increase its attractiveness, efficiency.

The technical result is achieved in that the control device can be made in the form of either a control circuit with a controller, and / or a microprocessor control system. In this case, the controller can be equipped with either an plug-in microcard, or a microswitch, or an optical sensor.

The technical result is also achieved by the fact that the electrical terminals can be either power terminals for a control device located inside the diffuser, or control terminals for a control device located outside the diffuser.

The proposed Lamp allows you to expand the decorative and artistic capabilities of lamps of this kind through the implementation of color dynamic effects, namely, mixing various colors of radiation that occurs in the internal volume of the diffuser, on its surfaces and inside its walls.

In addition, it is perceived as truly decorative, its glow is aesthetically pleasing and it has a strong emotional effect on the individual's condition.

The proposed decorative multi-color lamp has a new original combination of elements, original elements, which allows us to conclude that the utility model is new.

The implementation of the utility model is not difficult, its elements are easy to manufacture, their production technology is known, they are quite cheap and replaceable. The proposal meets the criterion of "industrial applicability".

Embodiments of the invention

The invention is further illustrated by specific embodiments with reference to the accompanying drawings. The above examples of the manufacture of the Lamp are not the only ones and suggest the presence of other implementations, the features of which are reflected in the totality of the features of the claims.

The proposed Lamp (see Fig. 1, 2) contains two radiation sources, consisting of two sets of clusters with LEDs 1 mounted on boards 2 installed on the base 3, and two control devices 4. (in this case, two control circuits with controller 4, hereinafter referred to as “control circuit 4”) also installed on the boards 2.

LEDs 1 are arranged in three LEDs 1 of different colors (for example, red, blue and green) in a cluster. Base 3 is made composite. The first set of clusters is placed on the upper flat surface of the first part of the base 3 — six boards 2 are installed along the perimeter of the hexagon with LEDs 1 having a large radiation angle, for example, more than 50 degrees. In the center of the first part of the base 3, another board 2 is fixed with the first control circuit 4 (see Figs. 1 and 2, cross section "A-A" of the right half of the Lamp). A groove is made on the side of the second part of the base 3 to accommodate the second set of clusters on the boards 2 (see FIG. 1, not shown in FIG. 2), one of which contains the second control circuit 4 (not shown in FIGS. 1 and 2 shown). Along the central axis of the base 3 in its three parts, a hole 5 is made, which is designed to accommodate electrical leads 6 (in this case, power leads 6) connecting the control circuits 4 and the power source (not shown in the figures).

In the base 3, the first and second parts of the diffuser are fixed, namely the outer 7 and inner 8 diffuser-reflectors. An external diffuser-reflector 7 is fixed between the third and second parts of the base 3, below the groove to accommodate the second set of clusters, and has a surface that has not only reflective properties, but also scattering. The internal diffuser-reflector 8 is fixed between the second and first parts

base 3 and has both surfaces frosted (diffusely reflecting), i.e. possessing scattering properties to a much greater extent than the inner surface of the external diffuser-reflector.

In the output aperture of the internal diffuser-reflector 8, a third part of the diffuser is fixed - a convex dome 9 made of milk-colored plastic, Between the edges of the outer 7 and inner 8 of the diffuser-reflectors, i.e. in the output aperture of the external diffuser-reflector 7, limited by the output aperture of the internal diffuser-reflector 8, the fourth part of the diffuser is fixed - an annular concave ceiling 10 made of milk-colored plastic.

The lamp works when the power source is connected to the mains. The power source can be a converter of alternating mains voltage 220 V to DC voltage, with a rating of, for example, 5 V, 9 V, 12 V. Power supply of LEDs 1 is carried out in dynamic mode using control circuits 4 in accordance with predetermined known intensity change programs LEDs 1 of different colors in each radiation source. A radiation source in which LEDs 1 of three primary colors are used, namely, red, blue and green, allows to obtain the greatest number of colors and shades visible to the human eye. As a result, with different and temporally changing luminescence intensities of the LEDs 1 of each particular radiation source, a continuously changing color gamut arises in the corresponding part of the diffuser, since intermediate colors and shades are formed by mixing the emissions of the LEDs 1 of different colors. Such mixing occurs in the volume of each respective part of the diffuser and

- if the volume is limited by the outer 7 and inner 8 diffuser-reflectors and concave ceiling 10 (the fourth part of the diffuser), mixing will also occur on the inner surface of the outer 7 diffuser-reflector, on the outer surface and in the frosted part of the walls of the inner 8 diffuser-reflector and on the surfaces and inside the walls of the concave ceiling 10, and

- if the volume is limited by the inner 8 diffuser-reflector and a convex ceiling 9 (the third part of the diffuser), mixing will occur on the inner surface and in the frosted part of the walls of the inner 8 diffuser-reflector, as well as on the surfaces and inside the wall of the convex ceiling 9.

If the sources of radiation installed in different volumes of the diffuser use programs that implement various color changes over time, then such a Lamp as a whole has an exceptional decorative effect associated with the dynamic contrast of color schemes observed in two volumes of the diffuser.

If the radiation sources installed in different volumes of the diffuser use programs that implement matching color changes over time, then such a Lamp is also interesting, although less decorative.

The second modification (see Figs. 3 and 4) differs from the first only in that the cut glass 9 is fixed in the output aperture of the internal reflector 8, and the annular cover 10 is a flat ring from a polarizing interfering film. Both shades 9 and 10 have transmitting, refracting and scattering properties, but to varying degrees. Note that a cross section of the right side of FIG. 2 will also be valid for the second example. Figure 4 on a cross section "BB" of the right half of the Lamp shows the LEDs 1 on the boards 2, placed in the grooves in the second part of the base 3, which also illustrates the first example.

In this embodiment, the improved decorativeness of the Lamp similar to that described in the first example can be achieved.

In a modified second modification (not shown in the figures), faceted crystal is installed instead of faceted glass, and instead of a film ring, the dome 10 is also made of faceted crystal set by sectors in a metal frame.

The proposed modifications with proper sealing of at least the radiation source and electrical leads can be operated in a humid environment, including when immersed in water.

Improving the decorativeness of the Lamp is due to the realization of the possibility of simultaneous illumination of LEDs of at least two colors according to any known program. As a result, it becomes possible to obtain intermediate colors due to mixing emissions of LEDs of different colors, i.e. obtaining various color effects, increasing the attractiveness of a decorative multi-color Lamp.

Industrial applicability

The proposed utility model allows you to create very decorative, light fixtures that are very simple to manufacture, inexpensive, affordable for a wide range of uses and at the same time very effective and attractive, beautifully aesthetically and emotionally perceived by people of different temperaments. The proposed designs can be used both as independent Lamps with an interesting color scheme, and be part of other more complex interior ensembles. This determined the variety of their use both in the interiors of apartments, offices, for decorating shop windows and tables in shops, cafes, restaurants, clubs, hotels, other rooms, and in parks, gardens, personal plots, etc., as well as for illumination of fountains, reservoirs and other objects, and, in addition, as an auxiliary tool in medical and sanatorium institutions.
