    The invention relates to a lighting and heating body with light sources, preferably LED lights, and a heating element, according to the preamble of claim 1.
    Especially in large-scale office and business buildings, production and event halls, but also in restaurants and hotels as well as in private residential areas, there is sometimes the problem of energy-saving supply of local areas with heat and light. When using water-bearing systems, the problem of sufficient insulation of the water-carrying lines to the place of the consumer and the sometimes unacceptably slow heating of the environment. Supplying individual workplaces with light and heat can lead to difficulties, especially on large areas. Above all, the heating convection-based heating systems show disadvantages, if it is the volume of space to be heated is large in relation to the used space volume of the local workplace. In this case, a comparatively large amount of energy has to be used for local heating at the workplace, which leads to useless energy consumption. If energy-saving LED systems are to be used for lighting, the temperature sensitivity of LEDs (light-emitting devices) must also be considered, which can lead to a reduced lifetime of the LEDs and does not play a role in normal ambient temperatures, but when used in close proximity to heating elements very likely to cause problems.
    It is therefore the object of the invention to provide a lighting and radiator which can heat and supply local areas quickly and energy efficiently, even if the local area is part of a large volume of space. The lighting and radiator according to the invention should also be subsequently installed easily and at low cost and be used flexibly in different areas of space.
    These objects are achieved by the features of claim 1. Claim 1 relates to a lighting and heating elements with light sources, preferably LED lights, and a heating element, is proposed in the invention that a sheath body is provided with a thermally insulating sheath core, which is enclosed by an outer sheath, wherein the heating element is designed as a voltage applied between the outer sheath and the sheath core on the inside of the outer sheath electric surface heating element, and the light sources are arranged in an axial opening of the sheath body, or on a voltage applied in the axial direction of the sheath body. The electric
    Surface heating element generates heat mainly in the form of infrared radiation and does not cause direct heating of the room air, but of object surfaces on which the infrared radiation impinges. The room air is heated indirectly by the heated objects. In the case of an electric surface heating element, the main radiation direction is oriented perpendicular to the surface heating element, although the heat radiation, of course, also takes place in a radiation angle to the main radiation direction. Since, according to the invention, the electrical surface heating element rests against an outer envelope of a jacket body, the heat radiation therefore takes place mainly perpendicular to the jacket surface, ie in the case of a cylindrical jacket body in the radial direction of the jacket body. The light sources are arranged according to the invention in an axial opening of the sheath body, or on a voltage applied in the axial direction on the sheath body. The light sources are therefore not directly exposed to the infrared radiation of the Flächenheizelements due to the geometry of the lighting and heating body according to the invention and are therefore not directly heated by her. Of course, the surface heating element also causes heating of the sheath body itself, with excessive heating of the light sources arranged in the aperture or on the main body being avoided by the thermally insulating sheath core provided according to the invention. Thus, temperature-sensitive LED elements can be used together with electric surface heating on the same lighting and radiator, provided that it is designed according to the invention.
    It is preferably proposed that the sheath body has an annular base surface and the sheath core has an inner circumferential surface which is provided with an inner sheath bounding the axial aperture. This measure allows a material-saving and thus weight-reducing design, whereby even elegant designs can be implemented. The arranged in the axial breakdown light sources can be attached directly to the inner sheath, or on a support plate, which traverses the axial aperture and is inserted into the inner sheath.
    The electrical surface heating element is preferably designed as a heating conductor arranged in or on a flat carrier, in particular made of a nonwoven or woven fabric. The heat conductor can be woven in about a glass fiber fabric or fleece, or in an electrically insulating plastic. For the jacket core, it is proposed that it is constructed of a free-flowing insulating material, preferably of vermiculite or expanded glass. In particular, for the proposed structure consisting of a base body and an inner and outer sheath disposed thereon, a jacket core volume is available, which can be filled by a free-flowing insulating material. The free-flowing insulation material ensures optimal filling of the jacket core volume and can be produced quickly and easily.
    The invention will be explained in more detail by means of embodiments with reference to the accompanying figures. It shows the

    With reference to FIGS. 1 to 4, different embodiments of the lighting and heating body according to the invention will first be shown. The shell body 1 in each case has an annular base and top surface and can between the base and top surfaces of a conically shaped outer shell surface with a cylindrical inner surface (Fig. 1), a cylindrically shaped outer shell surface with a cylindrical inner surface (Fig. 2), or a convex In the embodiments according to Figures 1 to 3, the lighting and heating body according to the invention is provided with retaining tabs 2 which are fastened to the top surface of the cover body 6. However, the retaining tabs 2 can 4 can also be fastened to the base body 5 and to the covering body 6, as shown in Fig. 4. According to Fig. 4, the lighting and heating body according to the invention has a cylindrically shaped outer shell surface with a cylindrical inner surface, but can be compared to the embodiment according to FIG. 2 hung by 90 ° twisted the effective radiation cone in the room for heating purposes, which may be advantageous depending on local requirements.
    However, the structure according to the invention is the same in all embodiments according to FIGS. 1 to 4. The sheath body 1 is enclosed by an outer sheath 3, at the inside as will be explained in more detail an electric surface heating element 4 is applied, in the axial direction of the sheath body 1 is a base body 5, which forms the base of the sheath body 1, wherein the main body 5 is executed in the embodiments shown as an annular disc. The cover body 6 forms the top surface of the jacket body 1, wherein the cover body 6 is also executed in the embodiments shown as an annular disc. The sheath body 1 has an axial opening 8, which is bounded by an inner sheath 7. As indicated in FIG. 2, a carrier plate 15 crossing the aperture 8 can be used in the axial aperture 8, to which the light sources 14 are attached with their power supply. The light sources 14 can also be attached directly to the base body 5, as shown in FIG. 4, in this case, the sheath body 1 could also be formed as a solid body without axial aperture 8, for reasons of material and
    Weight saving, however, the embodiments according to FIGS. 1 to 4 is preferred. In this way, even elegant designs are possible. Subsequently, a possible construction of a lighting and heating body according to the invention will be explained with reference to FIGS. 5 to 11. 5 shows a first manufacturing step of a lighting and heating body according to the invention, in which the main body 5 is prepared. In the exemplary embodiments shown, the main body 5 is designed as an annular disk of, for example, a temperature-stable plastic. The main body 5 can be made approximately as an injection molded part and has an outer groove 9 and an inner groove 10. Furthermore, four mounting rods 11 are attached to the main body 5 in the illustrated embodiment.
    The light sources 14 (not visible in FIG. 5) could, according to the embodiment of FIG. 4, be fastened to the underside of the main body 5 and are preferably designed as LED elements. LED elements have a high energy efficiency, a long life and low operating voltages, but the luminous efficacy of LEDs is particularly dependent on the ambient temperature and the dissipation of the heat generated. In practical use, care must be taken to ensure good dissipation of heat, especially in the attachment areas of the LEDs, in order to avoid aging and damage processes. Although the light from the LEDs does not contain any infrared components, its generation releases heat, so the LEDs themselves heat up. Modern designs for LEDs effectively dissipate the generated heat to increase the lifetime with the same light output. However, due to strongly fluctuating or high ambient temperatures, the life of the LEDs can be significantly reduced. Therefore, the thermal load of the LEDs is to be kept low, with a usual safety distance of 30-35 ° C below the manufacturer's maximum permissible junction temperature is recommended. Since the junction temperature is difficult to access in practice for measurements, the user usually orientates himself to the working temperature measured at the solder contact. A LED specified for a junction temperature of 120 ° C may be operated at a maximum working temperature of about 90 ° C, but better at about 30-35 ° C below this temperature. If the working temperature permanently exceeds these critical temperatures, the service life is significantly reduced. Therefore, care must be taken in the construction of the lighting and heating body according to the invention that the mounting areas of the LEDs do not permanently exceed temperatures of about 60 ° C. Such a construction will be explained with reference to the following figures.
    FIG. 6 shows a second production step of a lighting and heating body according to the invention, in which the outer casing 3 is mounted on the base body 5 with the surface heating element 4 arranged on the inside. The outer sheath 5 is designed as a sheet steel and is inserted into the outer groove 9. The surface heating element 4 is designed as a fleece or fabric, in which a heating element is woven. The heating conductor is in electrical contact with an electrical supply line 12. In the embodiment shown, two heating conductors are connected in parallel in order to reduce the length of the heating conductors used and to achieve higher heat outputs at the same voltage.
    FIG. 7 shows a third production step of a lighting and heating body according to the invention, in which the inner casing 7 is mounted on the base body 5. Also, the inner sheath 7 may be designed as a sheet steel and is used in the inner groove 10.
    The main body 5 forms, together with the inner sheath 7 and the outer sheath 3, a jacket core volume, which can subsequently be filled with a free-flowing insulating material, as shown in FIG. 8. The insulating material may be about vermiculite or expanded glass flakes. FIG. 9 shows a further production step of a lighting and heating body according to the invention, in which the filling with the insulating material has been completed. In this way, an insulating jacket core 13 is formed, which also ensures sufficient electrical insulation with respect to the heating conductor and the electrical supply line 12. Vermiculite, for example, has a high melting point of 1315 ° C, so it can be safely used at the given temperatures. Due to its specific heat capacity of 1.15 kJ / (kg.K), it is also able to store heat well, both in terms of time and in terms of uniform surface heating, which also low surface temperatures can be ensured. The voltage applied to the mantle core 13 base body 5 and the inner sheath 7 heat up even during prolonged operation of the lighting and radiator according to the invention hardly, so that LEDs on the base body 5 or on the inner sheath 7 without significant reduction in their life can be arranged.
    The entire structure can be subsequently closed with a cover 6, as shown in FIG. 10 can be seen. For this purpose, the covering body 6 has bores which are pierced by the mounting rods 11, so that the structure can be screwed by means of the mounting rods 11. The cover body 6 is also executed in the embodiments shown as an annular disc about a temperature-stable plastic. Also, the cover body 6 may be made approximately as an injection molded part and has two concentric annular grooves in which the inner sheath 7 and the outer sheath 3 engage.
    Finally, retaining tabs 2 can be mounted on the mounting rods 11, with which the lighting and radiator according to the invention can be mounted approximately on a ceiling, as shown in FIG. 11 can be seen. This completes the assembly of the lighting and radiator according to the invention.
    Both the infrared radiation based Flächenheizelement 4 and the usable due to the structure of the invention LEDs as light sources represent energy-efficient consumers, so that a power-saving lighting and heating can be realized, in combination with photovoltaics can also be used exclusively renewable energy without the use of fossil fuels.
