Description

The thermally insulated ceiling lamp belongs to indoor lighting devices and contains new design and technological solutions.

The invention of this thermally insulated ceiling light can provide indoor spaces with uniform and adjustable light, while adding aesthetic perception.

Today on the ceiling lamp market there is a large selection of ceiling lamps, which are divided into groups in accordance with technological and design features. The current trend in the development of lamps is aimed towards increasing the use of LED light sources. But they, even taking into account the latest advances, are not capable of producing an emission spectrum close to the solar spectrum; in addition, they have a much smaller angle of luminous flux - the angle of light emission from an LED is 120 degrees.

Since all LEDs are made on the basis of a blue LED, they always have a blue spectrum of radiation, which causes the pupil of the eye to reflexively dilate, and this negatively affects vision - it seems to us that we are looking at welding, and not at a lamp. In other words, when we see that the LED lamp is very light, it means that our pupils are dilated. I checked this fact in practice - I measured the diameter of the pupil of the test person in natural (sun) lighting and when illuminated by the light of an LED lamp LED G45 4100K E27, 455 lm from the South Korean company REMEZ, which positions its products as the most harmless lamps in the world - spectrum radiation is as close as possible to the solar radiation spectrum. Measurements showed that in natural daylight (sunny summer day, indoors), the diameter of the subject’s pupil was approximately 2 mm, and when illuminated by the above LED lamp, the pupil diameter increased to approximately 4 mm! Moreover, the more you turn your head towards the lamp, the wider the pupil, but it should be the other way around! Therefore, LED light is still considered technical and should not be used in residential areas.

An attempt to avoid the blinding effect of an LED lamp was made in patent RU 115443 U1 dated April 27, 2012, which has a base in the form of a reflector with edges curved down. In the center of the base, there is a heat-dissipating profile with boards with LEDs installed on its sides. The LEDs located in the center of the base shine in different directions horizontally, so part of the light is reflected from the reflector base, and the other part of the light is directed downwards. With this design of the lamp, other parameters deteriorated - the overall brightness and lighting angle decreased, the design became more complicated, and the ceiling was not illuminated at all. There are quite a lot of such patents, but they cannot change the physical essence of the light source.

All modern LED lamps are divided into two groups: one group has direct light from LEDs, which are covered with a common matte shade, and the second group is made in the form of various geometric shapes, where LEDs shine at the ceiling - creating reflected light. Such and similar lamps have a developed surface that actively attracts dust, which reduces the overall level of illumination, and under the influence of temperature, it is baked on the surface of the lamp, i.e. periodic maintenance is required.

The matte plastic lampshade is also not ideal - it partially reflects the light with an internal, glossy surface, and the other part of the light is scattered inside the plastic. The remaining luminous intensity decreases quadratically to the distance, i.e. fades quickly, so you have to use more powerful LEDs. Moreover, for the reasons stated above, such light is far from the natural radiation spectrum.

Another extensive layer of ceiling lamps is occupied by lamps using fluorescent lamps. Such light sources do not harm vision, but have a rather narrow emission spectrum, which is also far from the natural emission spectrum of light. As an example of such lamps, you can specify the RF utility model patent No. 47074, F21S 8/02, 2005, the RF utility model patent No. 100585, F21S 8/00, 2010, or the RF patent No. 2254516 for the invention of the MPK F21V 7/10, 06/20/2005 All of them have the same, square design, where mirror reflectors and fluorescent lamps with power wires are located in parallel. The design difference between these patents is contained in small details - the intervals between lamps and their number, the shape and number of reflectors, the angle of inclination of the reflectors, etc. Therefore, they have the same advantages and disadvantages. Such ceiling lamps, collectively called “Armstrong”, have been widely used in industrial and public spaces for decades. They even contributed to the development of an entire industry - the construction of suspended ceilings. Their advantages are harmlessness to vision and relative cost-effectiveness. Among the disadvantages are low resource, low level of illumination and insufficiently aesthetic appearance to be used in residential premises.

Therefore, ceiling lamps for residential premises have created their own aesthetic layer, which is focused on high-quality design and even artistic taste. Such lamps use aesthetic and even beautiful metal fittings in their design, and glass of various shapes and colors is used as shades. Glass is used in lamps not only because of its great aesthetic possibilities, but also because glass can withstand high temperatures, which are heated mainly by incandescent lamps. As an example of a typical residential ceiling lamp, you can consider patent No. RU 18 296 U1 dated September 27, 2000, where there is a description of a lamp in the form of a ceiling chandelier, which has a base - a body with an attachment point to the ceiling, to which several holders can be attached lamps with shades. Today, this design is typical for many lamps, not only ceiling, but also wall - for example, sconces. Even if we turn this design upside down, we will get a table lamp. Today, absolutely all lamps that use glass shades or glass fragments and incandescent lamps as a light source are attached directly to metal fittings, i.e. use metal fittings as a cooling radiator! LED lamps use an aluminum profile or aluminum radiators for cooling, but the shades are also attached directly to the metal body.

The modern variety of ceiling lamps is determined mainly by design solutions, rather than design features. Therefore, when developing a new thermally insulated ceiling lamp, the main technical tasks were set:

1. The lamp must produce the maximum possible illumination with the maximum possible angle of light emission, i.e. be effective.

2. The lamp must provide light that is safe for vision, i.e. the emission spectrum should be close to the natural spectrum of the Sun.

3. The ceiling lamp must be universal and be able to use any technological feature of the light source - incandescent lamps, fluorescent lamps, LED lamps, etc.

4. Replacement of faulty light sources should be simple - without partial disassembly of the lamp structure.

5. The lamp must be electrically safe and fireproof.

6. The ceiling lamp should be compact so as not to occupy living space in rooms with not very high ceilings.

7. The lamp should not have a developed surface or volume in order to completely eliminate maintenance during operation, without losing aesthetic perception.

8. The ceiling lamp should have various aesthetic options.

9. The ceiling lamp must have a simple attachment to the ceiling surface.

10. The mounting of the ceiling lamp should allow you to change its orientation in the plane of the ceiling.

11. The design of the ceiling lamp should rationally use the volume of product packaging.

12. The ceiling lamp must have an electronic (contactless) system for switching light sources in a safe mode in order to extend their life.

All these requirements are met by the new thermally insulated ceiling light shown in FIG. 1.1.

To create an innovative ceiling lamp that meets all the points of the above-mentioned list of requirements, we had to find new design, technological and design solutions:

- the first two points of the requirements were solved using a design solution - to position the light sources perpendicular to the base and use a halogen lamp with an E27 base as a light source. A halogen lamp with an E27 base provides a luminous flux angle of 320 degrees and has the widest spectrum of light emission, close to the solar spectrum - there is even infrared radiation that emits heat, like the Sun, which creates comfort in the room.

- the third point of the requirements is ensured by the use of a new compact and standard E27 base, manufactured by REXANT. The E27 standard allows the use of a light source of any technology and the required power.

- the fourth point of the requirements is ensured by the use of shades open on one side, this allows you to change lamps without disassembling the lamp.

- the fifth point of safety requirements is resolved thanks to the use of thermal insulation of the glass shade from the metal body - the base of the lamp.

- points six to eight of the requirements are provided with design solutions that make it possible to completely eliminate maintenance during the period of operation and use various options for the appearance of components to create an aesthetic variety of the ceiling lamp.

- the ninth and tenth points of the design requirements are fully met - the ceiling lamp is attached with just one screw and can be rotated around the mounting axis to the desired angle in any direction.

- the eleventh (11) point of the requirements - harmonious use of the volume of product packaging, is achieved through the use of harmonious sizes of the main components of the ceiling lamp.

- the twelfth (12) point of the requirements is provided by the development of a new circuit for the electronic remote control unit Fig. 1.2, which performs contactless switching of light sources during periods of absence of high voltage in the network. This mode of switching on the light sources allows you to connect the load smoothly, without current surges, which significantly increases the life of the light source. In addition, control occurs using a conventional switch, without the use of an additional device - a remote control with batteries, which increases the overall reliability of the system.

The well-known designs of ceiling lamps discussed above do not have the indicated advantages inherent in a ceiling lamp with thermal insulation. And, the main advantage of the new ceiling lamp is the thermal insulation of the glass shade from the metal base! This design and technological solution allows us to lower the overall temperature of the lamp, which makes it even safer to use and allows us to simplify the entire design - make it compact. The compactness of the ceiling lamp provides another very useful property - the lamp does not require maintenance for its entire service life!

Aesthetic diversity is provided by different colors, patterns and types of base surfaces, as well as a variety of patterns and shapes of installed glass shades.

These competitive advantages are crucial for the successful commercialization of the invention, since we are talking about the mass production of a domestically produced consumer product. The purpose of the invention of a thermally insulated ceiling lamp is to achieve these advantages.

The essence of the invention will become more clear when considering the design of a real device for a thermally insulated ceiling lamp, accompanied by graphic materials.

In FIG. Figure 1.1 shows a general view of a ceiling lamp with thermal insulation.

Ceiling lamp with thermal insulation, contains a metal base (1) in the form of a disk with edges curved upward, at an angle or at a right angle, for greater rigidity, on which any standard sockets, for example E27 (5) and a remote control unit (7) for electronic switching light sources (6) or just a terminal block. The height of the remote control unit (RC) corresponds to the depth of the base bowl in order to ensure that some of the heat is removed to the ceiling and serve as a limiter for base deformation when attached to the ceiling through a special hole (8). The lampshades (2) are equipped with thermal insulation in the form of an o-ring seal (3), which is located in the technological hole of the lampshade and acts as a barrier to heat. This prefabricated structure of the lampshade is connected by its mounting hole to the E27 socket and secured with a plastic nut (4) of the socket.

To increase the rigidity of the base for the five shades of Fig. 6, stiffening ribs 9 and a central bushing for mounting to the ceiling 10 were added, through hole 8.

For the industrial implementation of this invention, it is proposed to use a base (1) in the form of a metal disk with a curved edge at an angle or at a right angle to create greater rigidity, on which all other parts of the lamp are mounted. First of all, any standard cartridges (5), for example E27, are installed on the base, then a remote control unit (7) or simply a terminal block is installed and a connection diagram for the installed cartridges is formed. Then we install the lampshades (2), having previously inserted the thermal insulation sealing ring (3) into the technological hole of the lampshade. Thermal insulation of the lampshade is made in the form of a sealing ring made of heat-insulating material, in this case silicone, but other materials can be used - fluoroplastic, fluorine rubber, etc. In some cases, thermal insulation material in the form of a ring gasket can be used. With this, the assembly is complete. All that remains is to connect the power cable.

The use of a new technological solution in the design - the use of thermal insulation of a glass lampshade, made it possible to attach the lampshades directly to the base. This solution made it possible to create a compact lamp in compliance with safety standards, where the metal base serves as a cooling radiator and supports all parts, and the hot shades are insulated with thermal insulation.

The present invention of a ceiling lamp with thermal insulation can be used for high-quality, reliable and easy-to-use lighting in all interior spaces for a long time.
