Definitions

  • This invention generally relates to the art of constructing light fixtures equipped with high brightness light sources, i.e.: "Compact LED light bulbs", with a standardized structure, will replace traditional incandescent light bulbs.
  • This invention falls into the field of lighting technology and its solutions are designed for general lighting applications.
  • CFL compact fluorescent lamps that try to emulate characteristics of traditional filament lamps. Their advantage is a very low power consumption and the fact that they fit easily in to the existing lamp holders; but, such energy-saving lamps also have serious physical disadvantages.
  • the disadvantages include, low color rendering index (CRI) - color fidelity of the illuminated object, emission of harmful UV radiation, the presence of toxic mercury, relatively short life in places with frequent switching, a tendency to overheat in the enclosed fixtures, they emit electromagnetic smog because they operate on the principle of discharging excited high-voltage pulses, etc.
  • CRI color rendering index
  • the public has long been reluctant to buy CFL bulbs, not just because of the high price, but also because of the not too convincing characteristics described above.
  • HB LED diode in extremely low power consumption, high efficiency in converting electricity to light, (Watt /lumen conversion), color rendering index, size, design variability, by speed of switching frequency, palette of colors, wide variety of electronic control, durability, designs for low voltages, and the possibility of a combination with solar technologies, etc.
  • Watt /lumen conversion high efficiency in converting electricity to light
  • color rendering index size
  • design variability by speed of switching frequency
  • palette of colors wide variety of electronic control
  • durability designs for low voltages, and the possibility of a combination with solar technologies, etc.
  • HB LED diode also has one very serious drawback. This drawback is great sensitivity to the operating temperature, which must be strictly controlled for proper, long-term operation. For HB LEDs, it is necessary to conduct the excess heat away, quickly and efficiently.
  • LED light bulbs which are offered for substituing classic incandescent bulbs. They have different sizes, different thread diameters and they are designed to fit into old lamps and sockets. Their advertised advantage of compatibility is also their major disadvantage. The mistake is that they are installed into old lamp holders that are not designed for these alternative light sources at all.
  • Such bulbs are a combination of at least one LED chip, one cooling element intergrated directly into the light bulb and fitted by the driving electronic. Due to the limiting dimensions of such a LED bulb, the cooling element is too small to work at a high performance. The actual trend to integrate the cooling unit directly into the body of the LED bulb is restrictive, inefficient and impractical.
  • the shortcomings in existing LED lighting solutions are eliminated by a "compact arrangement of the fixture and the compact LED light bulb" according to this invention. It could be classified as an HB LED lamp that is a set of components, where two of them are essential for functionality and reliability.
  • the first essential element is a LED module designed as a compact light bulb equipped by an HB LED chip.
  • the second essential element is the lamp fixture itself consisting of a body - holder.
  • the system contains other, but from the point of the invention, less essential standard mechanical and electrical components.
  • a transformer electronically regulated power supply or pulse regulated power supply (PWM), shade, screws, ligaments, cablings, optical accessories and other mechanical and electrical interfaces serving the interconnection of the compact LED bulb and the compact lamp fixture.
  • PWM pulse regulated power supply
  • the nature of the invention is that the lamp fixture and the compact LED bulb are connected through both mechanical and electrical interface and also through mechanical and thermal interface.
  • the LED bulb is connected through a thermal bridge to the lamp holder functioning as a heat absorber-radiator for efficient conduction of the heat from the bulb towards the lamp holder's heat dissipating surfaces.
  • the compact LED light bulb itself includes at least one semiconductor LED chip module and/or optionally more structured LED units which are through the electrical, mechanical and thermal interface connected to the thermal bridge-body of the bulb.
  • Some versions of such bulbs have the mechanical, thermal and electrical interface located on the bottom side of the bulb's body.
  • Other versions have the connector installed from the side (optionally also through the optical cover) of the bulb.
  • the optical cover (shade) of the compact LED bulb is firmly fixed to the body of the thermal bridge.
  • acceptable optical covers which can have various forms and can be fully transparent or partially transparent (crystal, frosted or milky glass).
  • Compact LED light bulbs are designed so that one side of the thermal bridge is fitted by the semiconductor LED chip module; the other side of the thermal bridge is used as the interface for the mechanical, thermal, and electrical connection.
  • Some versions of the LED light bulbs could have the contact area from the side of the heat bridge of the compact LED lights.
  • Further applications of the compact LED light bulb could be provided with mechanical handles, clamps and fixations.
  • the embedded semiconductor chip LED module could be connected to a passive or active electrical or electronical component. These components may be a thermistor, resistor, diode, or another type of semiconductor, etc.
  • a compact LED light bulb can be completed by a temperature sensor and/or light intensity sensor and/or at least one element protecting against harmful static electricity.
  • Compact LED light bulbs can be fitted by both; the HB LED semiconductor chip module powered by a DC current or by LED chip modules powered by an AC current from the public grid (230 or 110V) without using an additional source.
  • Another essential component is the light holder itself, where the decorative shaped surfaces of the fixture serve as a cooler and radiator. They are conducting the surplus heat away from the compact LED light bulb.
  • the lamp holder's surface should have sufficient dimensions that would efficiently absorb and divert the excess heat away and dissipate it into the surrounding space. It consequently follows that it should be optionally manufactured from a good heat conducting metal like aluminum, copper or produced from other materials like recently developed modern, heat conducting plastic materials, by molding, pressing or by a spark erosion procedure. There could be lamp fixture alternatives which require additional cooler radiators fixed to the lamp. In such cases, the additional coolers would be shaped as radiators with a structured surface for easier heat dissipation.
  • the electrical connection is made by standardized connectors where one part of the connector is fixed to the body of the light fixture, the counter part is integrated into the compact LED light bulb's body - heat bridge.
  • Advantages of a compactly arranged lamp fixture, assembled by a compact LED light bulb according to the invention is based on a different technical solution of the lamp, whose technical features have not been previously merged in one final product. This is about a new philosophy, utilization, organization and shape of elements.
  • the principle of the presented lighting system is based on a logical compilation of components whose physical properties and behaviors are taken into account. The appropriate choice of components and the reasonable design helped to get a modern and reliable product, plus a significantly less labor intensive manufacturing process. As a result, the presented construction is advantageous also from an economic point of view.
  • the proposed components would be marketable through existing stores and/or also sold to the manufacturers or integrators for assembling them into their own products.
  • the existing light products are powered directly from the grid or through so-called step down power supplies where, during the transformation process, more than 20-30% of energy is wasted.
  • our new LED bulb is a low voltage and very economical system by its nature, it is highly suitable to integrate it into new lighting low voltage power grids. Like this, it is possible to save even yet more energy.
  • the compact LED light bulb is the light of the future also because of its direct compatibility with massively progressing solar photovoltaic technology. With LED light bulbs and a couple of solar panels on the roof or the balcony, it is definitively possible to be completely independent from the public electrical network.

  • Fig. 3 and 4 the basic construction and the arrangement of the compact light fixture and the compact LED light bulb are described. Only the light fixture 2 designed according to the invention and the LED light bulb constructed according to the invention are compatible.
  • the compact LED light bulb 1 is connected through an electrical and mechanical interface 6 to the light fixture 2. But at the same time, the compact LED bulb 1 is connected to the light fixture 2 through a mechanical and thermal interface, where the light bulb 1 is equipped by the thermal bridge 3 which transfers the excess heat toward the lamp's heat dissipating surfaces 13 of the light fixture 2. This means that the mechanical and thermal interface is created by the heat conducting bridge 3 of the compact LED light bulb 1 and by the heat dissipating surfaces 13 of the light fixture 2.
  • the construction of the compact LED light bulb 1 is shown in Fig.1 and is characterized by containing a semiconductor LED chip module 5. It is obvious, that one compact LED light bulb 1 contains at least one LED chip module 5 and that module may contain a chip or chips with one and/or even hundreds of LED semiconductor diodes.
  • the semiconductor LED chip module is electrically connected to the first part of the mechanical and electrical interface 6.
  • the electrical and mechanical interface 6 is in this case embedded directly into the heat bridge 3 and is realized by coaxially shaped standardized connectors.
  • To the internal pins of the connector are soldered electrical cables which are further connected to the pins of the semiconductor LED chip module 5 which is shown on the Fig. 2 and 3. For interconnection, standard thin copper cables are used.
  • the semiconductor chip LED module 5 is appropriately attached or mounted to the inner surface of the heat bridge 3 ⁇ for example, by screws or heat conducting tape. To increase the efficiency of the heat transfer, it is useful to apply a heat conducting grease between contact surfaces.
  • the shape of the body of the thermal bridge could be in the form of a disc which is the most common solution.
  • the thermal bridge 3 could also have a flat rectangular shape with a square base optionally fixed by screws in the corners of the thermal bridge 3. In such a case the holes and screws in the thermal bridge are considered as the fixation grips 9.
  • a linear compact LED light bulb 1 is fitted by a flat linear bar which serves as the thermal bridge 3 as it is shown in Fig.11.
  • the used materials for heat bridges 3 should have a very high thermal conductivity. For this reason the best materials for this purpose are copper, aluminum, their alloys and eventually newly developed heat conducting plastic or ceramic materials. From the above descriptions it is obvious that from the other side of the thermal bridge 3 the electrical pins of the connector are accessible.
  • the thermal bridge 3 also performs the function of the mechanical and thermal interface of the compact LED light bulb 1 because the outer side, in this case the lower side of the thermal bridge 3, has a contact surface 8 to dissipate the waste heat from the compact LED light bulb
  • the thermal bridge 3 is fitted also by the optical cover 7 of the compact LED light bulb 1
  • the cover can be designed in a variety of shapes like bulbs, balls, spheres, or tubes and manufactured from glass or plastic. As it is shown in Fig.
  • the compact LED light bulb 1 could also be designed as rectangular or pyramid shaped hollow bodies.
  • the method of their mechanical attachment is given by the materials used. In the case of the metal and plastic bonding, the best procedure is gluing.
  • it can be to the compact LED light 1 bulb and to the semiconductor LED chip module 5 connected at least one passive and/or passive electrical or electronical component. These components may be a transistor, diode, thermistor, resistor, capacitor, and so on.
  • the compact LED light bulb 1 could also be fitted by a temperature sensor, optical sensor and by a protective element against harmful static electricity.
  • the second compatible element of the solution is the body of the lamp/light fixture itself 2, whose decorative surfaces 10 are functionnig as the heat absorbing surfaces 13 of the light fixture 2, which serves as a cooler for the evacuation of surplus heat from the compact LED light bulb 1 as it is whole and partly shown in Fig. 3 and 4. It is obvious that the surfaces 10 must be designed so that they would be able to dissipate the excess heat into the surroundings. It follows that they should be manufactured from a thicker metal by processes such as: pressing, molding and spark erosion procedures, from a material with very high heat conducting properties.
  • the thermal bridge 3 is tightly adjacent to the heat absorbing surfaces 13 of the light fixture 2. This is possible to achieve by a ring 12 with an external thread, fixed to the body 10 of the light fixture 2_and by a ring nut 14 with internal thread and surface which is adjacent with the thermal bridge 3_ as it is shown in Fig. 3 and 4. This solution serves the quick mounting of the compact LED light bulb1 on the compact lamp fixture 2.
