Description

Compact arrangement of luminaire and compact LED bulb

Technical field

The invention generally relates to the design of light sources fitted with high-power light sources, the so-called light sources. “Compact LED bulbs”, which, with their standardized design, replace conventional light sources. The invention generally falls within the field of lighting technology and its solution is intended in the field of general lighting.

BACKGROUND OF THE INVENTION

It has been more than thirty years since mankind has been using light sources powered by electricity. Initially, Edison's bulbs appeared, then arc lamps, neon tubes, later fluorescent bulbs or bulbs filled with various gases, and at the end of the seventies, energy-saving lamps were added, which are improved and miniaturized variations of old discharge tubes equipped with modern pulse electronics. The European Union has now progressively banned incandescent filament lamps. It was decided to withdraw from sales 100 watts first, 75 watts next year, and from 2012, all types of filament lamps of conventional design, except for small ones up to 35 W, will be discontinued in stores. However, this decision will have a shocking impact on the population used for many years to warm shades and radiation characteristics of these sources. Various alternatives or replacements have been offered on the market for a long time, but these far from satisfy the comfort or optical-hygienic properties of the original filament lamp. The main disadvantages of a filament lamp are its low efficiency or short life. Only 8% of the supplied electricity is converted to light, 92% is converted to heat, which is a waste by-product.

Alternatives such as halogen bulbs are more suitable for use than power light sources, ie more for spotlights.

Energy-saving CFL lamps try to mimic the characteristics of conventional filament lamps. Their advantage is very low power consumption and can be easily screwed into the recesses - holders of existing lamps. However, the energy-saving CFL lamp also has serious physical deficiencies. These include, for example, low CRI (color rendering index) - fidelity of color reproduction of the illuminated object, emission of harmful UV radiation, presence of toxic mercury, relatively short life in places with frequent switching on, tendency to overheat in closed luminaires because it works on the principle of discharge caused by very high impulse voltage. The public has long been reluctant to buy CFL lamps for their lamps, not only because of the high price, but also because of the lighting characteristics described above. The ever-increasing price of electricity has prompted the wider public to make greater use of these light sources, but it is clear that this is at the cost of great compromises.

With regard to compliance with EU standards, it is now almost certain that a real acceptable alternative for the future seems to be luminaires based on semiconductor HB LEDs (hereinafter referred to as HB LEDs). Over the past four years, HB LEDs have been used mainly for decorative lighting and have only progressed through the general lighting area. This is mainly due to the fact that the efficiency and power of HB LEDs have not been sufficient for conventional lighting, comparable to traditional light sources. However, the development in this area has progressed and HB LEDs of very high performance have appeared on the market, which in their light parameters do not fall behind their traditional competitors such as conventional filament lamp or CFL fluorescent lamp. Indeed, these new elements outperform traditional sources in many ways, for example in extremely low power consumption, high efficiency in converting electric current to light, where the indicator is (Watt / lumen), fidelity of color reproduction of light reflected from the illuminated object, dimensions, variability, speed and switching frequency, palette of miscible colors, electronic control options, long lifetime, ultra-low voltage design, combination with solar technology, etc. However, the HB LED with a very high output has one very important drawback. This is a high sensitivity to working temperature, which must be strictly observed for proper operation and exploitation of the long life potential. From each high-power HB LED, the excess waste heat must be removed to the luminaire area quickly and efficiently. There are currently quite a number of types of LED luminaires on the market, but most of them are mainly intended for decorative lighting, spot lighting, or as table lamps, bedside reading lamps, wall and building facades, or waterproof to illuminate colored fountains, etc. All mentioned sources are single-purpose and not suitable for general lighting of premises. Existing light sources are usually fitted so that the LEDs are directly fixed to the cooling element by means of screws and the power supplies are solved by cables, industrial interconnectors or soldered to the contacts. Such narrowly specified solutions are a logical solution for the aforementioned purposes, but are only suitable for small-series luminaires or custom-made installations. Conversely, such solutions are impractical and economically disadvantageous for mass expansion into general production, such as distribution to ordinary households. Not to mention the complications of ensuring their service, or arranging their replacement after the warranty period.

Another category in the current general lighting market is LED bulbs, which are offered as a substitute for conventional. They have different sizes, different thread diameters, connectors and are designed to fit into the original luminaires and their holders. Their compatibility advantage is actually a major disadvantage. This is because they are installed in the original, old luminaires, which are not at all adapted to alternative power replacements. Such bulbs are a combination of at least one LED, a heat sink integrated directly into the bulb and electronics. However, due to the limiting dimensions, such LED bulbs cannot operate at very high powers due to the limited dimensions of the cooling element. The trend of integrating the cooling unit into the bulb body is a limiting, inefficient and impractical solution. Especially in enclosed luminaires, such bulbs quickly overheat and waste heat has nowhere to escape. It is likely that such LED bulbs will only be an intermediate step in the mass introduction of LED technology into practice. In this way, the public will be able to use their old luminaires and will not have to invest in new-generation luminaires immediately.

In summary, the development in the field of LED lighting is revolutionary and therefore quite chaotic. There are practically no standards and norms. So far, each manufacturer has its own solutions. However, it is an effort that, as in other fields of technology, LED sources should be harmonized and standardized as soon as possible. This is necessary to simplify production processes, unify certification, easily identify the product to customers, compactness of the product, or parameters that are usually a prerequisite for the rapid introduction of new products on the market.

The band production of commercial LED luminaires requires a different solution to ensure the compatibility of the luminaires and the light sources to be fitted. It is desirable that the individual components be standardized so that they fit together in a simple manner, as is the case today with conventional light sources.

The above-mentioned shortcomings of alternative light sources as well as shortcomings of existing LED devices have evoked to technical solution of LED sources - luminaires that do not show the above mentioned shortcomings, by their principle push this modern technology to higher quality and which by their concept enable faster penetration into production programs or a regular business network.

This effort results in a compact arrangement of the luminaire and a compact LED bulb realized by the technical means described hereinafter.

SUMMARY OF THE INVENTION

These shortcomings of the prior art overcome the compact arrangement of the luminaire and the compact LED bulb of the present invention, which can be referred to as the HB LED luminaire, which is a set of components, two of which are essential for functionality and reliability. The first essential element is a compact LED bulb as a so-called. The LED module and the second essential element is the luminaire itself, consisting of a body as a body and other less essential standard mechanical-electrical components. Depending on the type and destination, the other less essential components of the compact luminaire and compact LED bulb are alone or in combination with each other: transformer, electronic control or pulse source (PWM), design shade, screws, fixings, cabling, optical accessories and mechanical / electrical interface through which a compact LED bulb and luminaire are connected. The principle of the invention is that the luminaire and the compact LED bulb are interconnected both via a mechanical-electrical interface and also through a mechanical-thermal interface such that the compact LED bulb is provided with a thermal bridge in contact with the heat-dissipating surfaces of the luminaire. Thus, the mechanical design of the compact LED bulb and the power supply to it is adapted for simple, fast and reliable fitting through standardized mechanical-electrical and mechanical-thermal interfaces.

The compact LED lamp itself comprises at least one semiconductor LED chip module, consisting of an ordered number of LED chips, which is electrically connected to the first part of the mechanical-electrical interface. In one case, the mechanical-electrical interface is incorporated directly in the thermal bridge. In the latter case, it can be installed outside the thermal bridge, ie it will be built from the side (through the optical cover) of a compact LED bulb. The optical cover of the compact LED bulb mechanically connects to the thermal bridge. Various embodiments of the optical cover are acceptable, which can thus be completely transparent or only partially transparent.

The mechanical-thermal interface of the compact LED bulb is designed such that a semiconductor LED chip module is placed on one side of the thermal bridge and on the other side, usually on the bottom side of the thermal bridge, a contact surface for heat removal from the compact LED bulb. For other applications, a solution is also possible where the contact surface for heat removal from the compact LED bulb is located on the side of the thermal bridge. For still other applications, a solution is also possible where the thermal bridge is provided with mechanical fasteners. The at least one semiconductor LED chip module of the compact LED bulb may be mounted in one or more planes forming a spatial formation such as a pyramid, a cone, a cylinder and the like.

From an electrical point of view, the compact LED bulb solution is such that for one application at least one passive or active electrical or electronic element is connected to at least one semiconductor LED chip module of the compact LED bulb. These elements may be a thermistor, a resistor, a diode, another semiconductor, and the like. The compact LED bulb may be supplemented with a temperature and / or light sensor and / or at least one static protection element. The compact LED bulb can be fitted with a HB LED semiconductor chip module for direct power supply of 230 Volts without the need for an external power supply.

The second essential element is the luminaire itself, especially its body as the body of the luminaire, whose metal, decorative surfaces also serve as a heat sink for dissipating excess heat from a compact LED bulb. These two essential elements - the luminaire and the compact LED bulb - cannot work separately, but only in symbiosis, because they are functionally interdependent.

The mechanical solution of the luminaire according to the invention is such that the heat-dissipating surfaces of the luminaire are in one case formed by the luminaire body itself. Obviously, this lamp body must be dimensioned so that it can dissipate excess heat into the environment. Accordingly, it will be made of thicker sheet metal, for example, by compression molding, or will be produced by machining, or will be cast and will be made of a material that dissipates well.

In the latter case, the heat-dissipating surfaces of the luminaire are an additional cooler which is attached to the luminaire body. This cooler will usually have ribs.

The electrical solution of the luminaire according to the invention is such that, in one case in the luminaire itself, the second part of the mechanical-electrical interface is integrated into the cooler as a standard connector. In the latter case, the second part of the mechanical-electrical interface is also attached to the lamp body in the form of a standard connector.

For some applications of the compact arrangement of the luminaire and the compact LED bulb, a power supply that is built into the luminaire body is necessary. In order to ensure the peak parameters of this light source, it is advantageous to have a power supply with a constant output current in the luminaire.

The advantages of the compact arrangement of the luminaire and the compact LED bulb according to the invention are that the proposed technical solution of the luminaire, in particular with high-performance LED chip modules, has combined two previously unused technical elements in the final product with a new philosophy of arrangement and use. The design principle of such a luminaire logically uses and takes into account the physical characteristics of the installed components. Their suitable choice and technical design will achieve considerably less laboriousness in the production of lamps. This will also increase the economic advantage of such products. In order to achieve compactness of the solution and standardization of individual elements, it seemed expedient to fit a new integrated LED light. compact LED bulb. Such a complex lighting unit, seemed to be the most suitable solution for rapid series production as well as for sale through the ordinary retail network. The intention of the design was to avoid the need for a qualified technician to handle it and to replace the bulb would be handled by a technically poorly skilled customer exactly as it is to replace conventional incandescent filament lamps or energy saving lamps. The principle of a luminaire with a compact LED bulb, i. - The LED module applied to the cooling element, which is made up mainly of the support body of the luminaire itself, is a principle that is new and not yet used. Such a way of using LED technology basically removes the negative barriers of thermal management that have hitherto prevented the spread of LED elements in general lighting. The proposed technology can be easily and quickly applied to any environment, although the intention is its rapid expansion mainly into homes and areas where previously used conventional filament lamp. The technology is tried and tested. It is flexible and very reliable. In fact, the light source conceived in this way has neither power nor dimensional limitations, it is easily dimensioned with high light output in the order of thousands of lumens. By standardization of components it is possible to create so-called. puzzles, so designers don't have to bother with technical pages to design their variations. These components would be marketable in the normal retail network. In the current state it is necessary to transform the mains voltage to a suitable power supply for driving the LED bulb. More than 20 to 30% of the energy supplied is lost. New generation luminaires will already be built at a low supply voltage. Central wiring and power supplies will be installed for the buildings, from which the energy for driving LED lights will be distributed. In this way, further savings are possible in the building. LED bulb is the light of the future also because of direct compatibility with solar photovoltaic technologies. With the help of LED lights and several PV panels on the roof or balcony it is possible to solve the complete independence of lighting in buildings from public electricity. network.

DETAILED DESCRIPTION OF THE INVENTION

Example 1

In this example of a particular embodiment, the construction of the basic compact arrangement of the luminaire and the compact LED bulb according to the present invention is described and shown in FIG. 3 and 4. Only the luminaire 2 constructed according to the invention and only the compact LED bulb 7 constructed according to the invention are compatible. Compact LED bulb as a so-called. The LED module is connected to the luminaire by a standard mechanical-electrical interface 6, but at the same time the compact LED bulb 1 is connected to the luminaire 2 through the mechanical-thermal interface so that the compact LED bulb 1 is provided with a thermal bridge 3 This means that the mechanical-thermal interface is formed by the thermal bridge 3 of the compact LED bulb 1 and the heat-dissipating surfaces 13 of the lamp 2. This describes the basic philosophy of the compact arrangement of the lamp 2 and the compact LED bulb.

1. The importance of the new luminaire concept is already apparent from this basic description. 2. For proper operation of high-power LED bulbs, heat as a waste product when converting electric energy to light must be removed from the LED semiconductor chip module 5 of the compact LED bulb. the bridge 3 to the heat-dissipating surfaces 13 of the lamp 2, which is the body itself - the body of the lamp 2, also as a design element of the lamp 2. Alternatively, the additional cooler 4 can be located outside the luminous beam angle of the lamp 2.

The construction of a compact LED bulb 7 as a so-called light bulb. The LED module is shown in FIG. 1 and is characterized in that it comprises a single semiconductor LED chip module

Obviously, each power LED bulb contains tens to hundreds of semiconductor LED chips, and so the compact LED bulb 1 contains a set of tens to hundreds of semiconductor LED chips. This semiconductor LED chip module 5 is electrically coupled to the first part of the mechanical-electrical interface 6. The mechanical-electrical interface 6 is in this case embedded directly in the thermal bridge 3 and in this case is realized by a standard pin connector. Power supply conductors from the semiconductor LED chip module 5 are soldered to the inner ends of the pins as shown in FIG. 2 and 3. The power supply conductors are standardly used Cu thin wires. The semiconductor LED chip module 5 is suitably attached to or attached to the inner surface of the thermal bridge 3, for example by means of screws. In order to increase the effect of the heat transfer, a thermal conductive paste can be applied to the joint. As shown in FIG. 2, the thermal bridge 3 is a disc-shaped flat body, which is a conventional solution. However, in variants of the compact LED bulb 1, the rectangular, rectangular, rectangular, thermal bridge 3 can be all for classic shape LEDs and screwed in the corners of the thermal bridge 3. In this case, screws and holes in the corners of the thermal bridge 3 are considered mechanical fixtures 9. For the linear compact LED bulb 1, the thermal bridge 3 is a flat strip as shown in FIG. 11. The thermal bridge material 3 must be characterized by a high thermal conductivity. Materials such as, in particular, copper and aluminum or their alloys are therefore suitable. It follows from the above description that the electrical outlets of the connector are accessible from the outside of the thermal bridge 3. At the same time, the thermal bridge 3 also functions as a mechanical-thermal interface in the compact LED bulb 1, since the outer, in this case the underside, of the thermal bridge 3 has a contact surface 8 for heat removal from the compact LED bulb 1. The thermal bridge 3 is structurally connected to the optical cover 7 of the compact LED bulb 1. In this case, it is in the form of a classic hemispherical canopy with a short cylindrical stem made of transparent plastic. As shown in FIG. 4, and in a variant embodiment, the optical cover 7 of the compact LED bulb 1 may be in the form of a hollow pyramid body. The method of attachment to each other is determined by the materials used. In the case of metal and plastic bonding is appropriate. Alternatively, in the compact LED bulb 1, at least one passive or active electrical or electronic element may be connected to the semiconductor LED chip module 5. These elements may be a thermistor, a diode, and the like. The compact LED bulb I can also be supplemented with a temperature and / or light sensor and / or at least one static protection element.

The second compatible element of the solution is the luminaire 2 itself, whose metal, decorative surfaces of the luminaire body 10 as its body represent the heat 11 of the luminaire surface 13, which also serves as a heat sink, to dissipate excess heat from the compact LED bulb 1. shown e.g. FIG. 1, 3 and 4. It is obvious that this luminaire body 10 must be sized so as to be able to dissipate excess heat into the environment. Accordingly, it will be made of thicker sheet metal, for example, by compression molding, or will be produced by machining, or will be cast and will be made of a material that dissipates well.

In order to ensure reliable heat dissipation from the compact LED bulb 1, it is suitable that the thermal bridge 3 abuts the heat-dissipating surfaces 13 of the lamp 2. This can be ensured, for example, by an external thread ring 12 screwed to the lamp body 10 and annular nut 14. with internal thread and thrust surfaces abutting the thermal bridge 3 as shown in FIG. 3 and 4. This solution also serves for fast mounting of compact LED bulb 1.

These two essential elements - the lamp 2 and the compact LED bulb 1 - cannot operate separately, but only in symbiosis because they are functionally interdependent. For complexity of the solution it is necessary to mention that according to the purpose and type of the lamp 2 and compact LED bulb 7, the less important components are individually or in combination with transformer, electronic control or pulse source (PWM), design shade, screws, fixings, optical accessories.

Example 2

In this example of a particular embodiment, the second structure of the compact arrangement of the luminaire 2 and the compact LED bulb 1 of the present invention is shown, which is shown in FIG. 5 and substantially described in the preceding example. The difference lies in the principle of the mandrel quick-clamping of the compact LED bulb 1 to the body 10 of the lamp 2. In this case, the thermal bridge 3 is provided with mechanical fasteners 9, which are two vertical mandrels. The locking is provided by a locking unit 11 with supply contacts as shown in FIG. 5th

Example 3

In this example of a particular embodiment, a third construction of the compact arrangement of the luminaire 2 and the compact LED bulb 1 according to the invention is described, which is substantially described in Example 1. The difference is that the contact surface 8 for heat removal from the compact LED bulb 1 is located on the side of the thermal bridge 3.

Example 4

In this example of a particular embodiment, a fourth compact compact LED bulb 1 according to the present invention is shown, which is shown in FIG. 6 and which is substantially described in Example 1. The difference lies in the fact that the mechanical-electrical interface 6 implemented by the standard connector is in this case installed outside the thermal bridge 3, that is to say the side of the compact LED bulb L

Example 5
