    LIGHTING BODY TECHNICAL AREA
    The technical solution relates to a luminous body, in particular for industrial or other lighting purposes, which utilizes a light emitting diode as a light source, which is also named as LED.
    STATE OF THE ART
    Current filament use as a light source bulbs, be it classic incandescent or halogen bulbs, but also fluorescent tubes and discharge lamps.
    Recently, thanks to the progress made in the field of light-emitting diodes, further LED, these elements also begin to be used as light sources for filaments, since they have the highest efficiency for the conversion of the electrical energy into the light (Im / W) of all commercially available light sources.
    There is a whole series of luminaires using this technology. There are also light sources with systems of several LEDs provided with sockets of common incandescent lamps, i. e.g. with E27, E14, so that these economical light sources can be screwed in place of the bulb. These light sources use the light generated by light-emitting diodes only very uneconomical, since the LEDs emit the light at an angle of about 100 ° -140 ° with a significant maximum in the axis.
    There is a whole series of patents which seek to emit light in filaments with LEDs. As an example of a possible way of this solution, e.g. document WO / 2009/055374, where a luminaire is described with a series of LEDs arranged in a specially shaped reflector. However, this solution of the adjustment of the luminous flux only partially solves the problem of the effective utilization of the emitted light, since the LEDs radiate most of the luminous flux at an angle of approximately 30-40 °, and provides for the correction of the direction of light rays at that angle a reflector is not a favorable solution. The result of application of the reflector to the light emitted by LEDs is a radiation characteristic with a significant maximum in the center and with a steep decrease in the intensity of the light towards the edges. This result can be considered as unsatisfactory since the aim of an optimal luminaire is to uniformly illuminate the entire required area.
    This goal can be achieved by using an optical element located in front of the LED. The optical element, when properly constructed, can provide substantially uniform light distribution on the illuminated surface. It is necessary to carry out the construction of LED lamps with the protection against the ingress of dust, because the layer on the surface of LED literally attracts the dust and it gradually comes to a lowering of the luminous flux; the importance of this problem is multiplied by the long operating time of LEDs, even in the order of tens of thousands of operating hours. There is a relatively wide assortment of plastic lenses that are often offered directly by the manufacturers of LEDs, however, it is necessary to provide all these lenses with a protective cover against the ingress of dust. The disadvantage of this solution is based on the fact that it significantly reduces the resulting effectiveness of the luminous element, since the light only partially passes through each separation surface during the passage, a part of the light is reflected and always remains unused. The ratio of reflected and transmitted light depends very much on the quality of the surface, in common glasses and plastics, these losses represent about 15 - 20%. By adding protective cover, the effectiveness is reduced by about 25 - 40% because the light has to pass through the separation surfaces air / lid material and lid material / air. The arrangement 1/10 Austrian pstentamt AT12 640U1 2012-09-15 of a common optical system with LEDs and with an increased coverage is further illustrated.
    BEING THE TECHNICAL SOLUTION
    The above-mentioned disadvantages are solved by the luminous body according to this technical solution. The luminous body comprises a base body, which is advantageously formed by a cooler. On this base body, a light source is arranged, which is formed by at least one LED, which is advantageously equipped on a printed circuit board with high conductivity. The essence of the technical solution is based on the fact that above the light source, a lid against the ingress of dust or water is arranged, which comprises an integrally formed therein optical member for rectifying the luminous flux from the light source, wherein the optical member disposed above the light source is. It is particularly advantageous to fasten the lid tightly on the base body, whereby a perfect seal is achieved and any penetration of dust or moisture into the space of the light source is avoided, thereby preventing a lowering of the light flux which can be exploited therefrom. By virtue of the fact that the lid comprises an integral optical member therein, losses when passing from one optical environment to another optical environment are avoided.
    The luminous element is advantageously provided with a lid whose optical member is formed by an aspherical lens. Their vertex is arranged with a particular advantage above the center of the light source.
    According to a further advantageous embodiment, the lid is provided in the lower part with a flange whose lower edge is shaped to be placed on the base body, and between this flange and the base body, a seal is attached. It is particularly advantageous then formed in the lower side of the base a Kreisnute for inserting a seal, wherein the seal is an O-ring, wherein the O-ring between the lower edge of the flange and the base body is arranged. With particular advantage, the lid of the filament is then secured to the body with a ring which presses the flange to the body and is provided with openings for screws for attachment to the body.
    According to a further embodiment of the filament has adhered to the flange according to this technical solution with the base body, wherein the adhesive is attached to the lower side of the flange and at the same time forms the seal. An advantageous embodiment of the adhesive is e.g. Contact adhesives, silicone gums and silicone adhesives, etc. It is important that the adhesive ensures a sealed connection of the lid to the body.
    The luminous body has after its further training on the body a processed group of light-emitting diodes, which are axially symmetrical one attached to the other, wherein the optical member is arranged axially symmetrically above these diodes with respect to the center thereof.
    According to a further advantageous embodiment of the filament is formed by a list of spaced-apart light-emitting diodes, wherein above each diode, a lid is attached to the optical member.
    According to a further advantageous embodiment of the luminous element has the optical member with its lower side close to the light emitting diode or in contact with this arranged.
    According to yet another advantageous embodiment, for the purpose of minimizing optical losses, the luminous body has filled the space between the lower side of the optical member and the light-emitting diode with a substance having at least analogous optical properties as the material of the optical member.
    The luminous element can, according to a further advantageous embodiment, be provided with a suspension for tilting the filament into different sides. The luminous element may further be formed by a group of light-emitting diodes, wherein these light-emitting diodes are arranged at least in two rows or in the form of a matrix. However, it is of course possible to have a further arrangement, e.g. a circular or in the form of another pattern, according to the need for lighting.
    According to a further aspect of this technical solution, a system of luminous bodies described above is presented where the individual luminous bodies are arranged in rows or in a matrix, wherein they are mutually independently for the purpose of the independent pivoting out of each filament are touched.
    OVERVIEW OF THE FIGURES IN THE DRAWINGS
    Fig. 1 shows an embodiment of the luminous element according to the prior art.
    Fig. 2 then illustrates an advantageous embodiment of the filament after the technical solution.
    Fig. 3 shows a system of luminous bodies arranged in two rows.
    Fig. 4 shows a system of luminous bodies arranged in the matrix 4x4.
    EMBODIMENTS
    The luminous element according to the prior art is illustrated in Fig. 1 and consists of a base body 1 to which an independent rectifying member 8 of the luminous flux from a light source 2 is mounted. Above this, a cover glass 7 is arranged, which ensures the cover of the whole system against the ingress of dust or water.
    The luminous element according to this technical solution is formed as shown in FIG. 2 by a base body 1, to which a light source 2 is fixed, which is formed here by a light-emitting diode with high light intensity. The main body 1 is advantageously made of aluminum according to this embodiment and is provided with ribs for dissipating the heat from the light-emitting diode, since it is advantageous for the life of the light-emitting diode to ensure their possibly best cooling. Even if it is an advantageous embodiment, this design of the base body 1 is not fundamental to the essence of the technical solution and not mentioned here as a limiting example of their execution. Namely, the main body 1 means the body of the luminous body to which the light source 2 and, advantageously, the lid 4 with the optical member 3 is attached. The basic body 1 can be formed in one piece according to this technical solution, but e.g. also from several interconnected parts. It is also possible to put together several independent basic elements in a whole, so that thereby a compact body 1 is formed with any amount of light sources 2. The basic elements according to this embodiment can e.g. Be modular elements, which allows easy assembly of the compact body 1. There are a number of possibilities for the formation of the body 1, as well as a lot of possibilities for attaching the light source 2 or the cover 4 with the optical member 3 thereto, any designer can certainly design this and therefore it is not necessary to deal with these possibilities here. It is important to note that a specific embodiment of the main body 1 or attachment of the light-emitting diode as the light source 2, or even the lid to the optical member 3 thereto in no way affects the nature of this technical solution and therefore can not lead outside the scope which is contained in individual claims. It is also important to be aware of the fact that the light source 2 can be formed not only by a light-emitting diode but also by a plurality of light-emitting diodes arranged together. The light source 2 is formed according to a particularly advantageous embodiment by a light-emitting diode which is equipped on a printed circuit board with high conductivity. The printed circuit board is advantageously attached to the base body 1 and represents the 3/10 Austrian Patent Office AT12 640U1 2012-09-15
    Supply of light-emitting diode with operating voltage safe.
    Above the light source 2, an optical member 3 is fixed, which rectifies the light from the light source 2. As already mentioned, a particularly advantageous embodiment of the optical member 3 represents an aspheric lens with cardioid characteristic, which will be further described. As is apparent from Fig. 1, the optical member 3 is an integral part of the lid 4 for the light emitting diode 2 and protects it, for. As against dust or spray or moist environment. The lid 4 is provided in its lower part with a flange 5, wherein between the flange 5 and the base body 1, a seal 6 is arranged. The lid 4 may be secured to an advantageous embodiment of the body by a ring with openings for screws, which is attached to the lid and, as is customary practice, fastened by screws to the body. Advantageously, a groove is formed in the flange 5, in which the seal 6 is inserted. The seal is particularly advantageously formed by an O - ring. However, it is also possible in another embodiment of the base body 1, the seal 6 z. B. to be arranged on the outer circumference of the flange 5, wherein the cover 4 is inserted in this case in the base body 1. Further, it is also possible the connection of the ring which holds the lid 4 to the base body 1, seal, etc. It is also possible the lid 4 to be bonded to the base body 1, for. As with silicone, and other options. It is important that in the connection of the lid 4 with the base body 1, no dust or moisture in the room where the light source 2 is arranged, can penetrate, which could lead to shortening the life and / or lowering of the radiated luminous flux.
    The design of the optical member 3 itself, advantageously the design of the aspherical lens, depends on many factors including the required beam angle, the required radiation pattern, the size and construction of LED, and is therefore not suitable to deal with it here. The calculation of the curvature of the aspherical lens according to given requirements will surely be designed by any expert dealing with this subject. Here it is important to consider the nature of the light-emitting diode that radiates the most in their midst. Therefore, it is advantageous to use an aspheric lens with cardioid characteristic, which suppresses this center and ensures uniform illumination throughout the radiated angle. However, besides the aspherical lens, it is possible to use another suitable optical member which will ensure the required distribution of luminous flux. This can z. As a normal lens or a Fressnel lens, a diffraction grating u. be a. Anyone who deals with the subject of passage of the luminous flux through optical elements can also ensure their design. It is important that the optical member 3 is incorporated in the lid 4 of the light source 2, that is, that it will form part of this lid 4, thus ensuring the protection of the light emitting diode in the light source 2 against the ingress of dust or moisture reduce the emitted light, and at the same time that it also allows the required adjustment of the characteristic of the luminous flux from the light source 2, without the losses during the passage through the lid 4 and optical member 3 are higher. According to an advantageous embodiment, the optical member 3 forms substantially the larger part of the lid 4 of the light source 2. Here it is important to be aware of the fact that there may be a whole series of embodiments of the lid 4 with the optical member 3, and so it's not possible to mention all of these remarks here.
    A great advantage of the aspherical lens in the function of a corrector of the luminous flux is the ability to achieve virtually any radiation pattern. As already mentioned, very advantageous from the standpoint of lighting is a cardioid characteristic, thanks to which a uniform distribution of the light can be achieved over the entire illuminated area. The aspheric lens may be made of glass, e.g. Example of a borosilicate glass or polycarbonate or another, optically suitable material. It is important to note that the optical properties of the material for the aspheric lens are not so much fundamental to the nature of the technical solution. 4.10
