Description of the invention: L invention households technical field 3 The invention relates to a light radiation heating device. In particular, the present description specifically relates to a radiation device for simultaneously heating indoor and outdoor surfaces and/or environments, but does not limit the application of the present invention to wavelengths suitable for use in the visible spectrum (eg, through iron quartz lamps) and infrared spectra. Other types of lighting devices or radiating devices that emit energy. Radiation heating devices using electrically powered lamps as heat sources are known. Regardless of the type of lamp used, in prior art devices, the lamp must be embedded in a retaining frame that contains electrical connections that energize the lamp and secure it in the frame. Since the operating temperature of the special lamp for such a device is high, in order to prevent the electrical connection from being damaged or the efficiency of the electrical connection being lowered under any circumstances, the electrical connection is made possible by high temperature resistance and low heat transfer efficiency. Made of materials. In prior art devices, in order to inhibit the penetration of dust or water in the area where the electrical connection is located in an outdoor application (so that a short circuit may occur) 'made of glass or any material that allows the operating wavelength to pass through as much as possible. The shield achieves a seal for the frame in which the lamp is contained. In all cases, the radiation emitted by the lamp must pass through the glass of the sealing frame, partially reflected, partially absorbed, and therefore only partially transmitted. Such a circumstance reduces the transmission output of the radiation of the heating device. In addition, the necessary materials for making electrical connections to the lamp (Tao, Mica, Cinnamon) 201103355 are fragile or very hard anyway. Considering the fact that the electrical connection also acts as a support for the lamp, even small shocks or vibrations transmitted to the retaining frame can severely impair the integrity of the lamp. In addition, the radiation reflected by the glass into the frame causes an increase in the temperature inside the frame. Thus, the different coefficients of thermal expansion of the lamp and the electrical connection cause mechanical stresses within the lamp which can cause breakage of the lamp. In order to avoid the above drawbacks, the applicant has proposed a radiation device that does not use glass, as disclosed in the document WO 2005/036928, which is provided with two elastic branch elements made of a heat resistant elastomer material in opposite An end-supported linear lamp that is resiliently mounted to the lamp to conveniently protect it from shock and vibration, and that is resiliently engaged with the support structure. The electrical terminals of each lamp are housed in a hermetically sealed holding cavity such that the electrical components are properly protected from possible dust, moisture and/or escaping water penetration. Applicants have also discovered that prior art glass-free radiation devices can be further improved with different considerations, first in terms of structural simplicity, dimensional tightness, reliability of use, and production costs. In fact, the requirement that the electrical terminals of the lamps are sealed in the respective holding chambers that are sealed to each other to avoid the penetration of dust, moisture, water and other foreign matter may encounter a problem that the device as a whole has a significantly complicated structure. Different assembled components increase the number of potential penetration points through which external materials penetrate into the electrical components, degrading device reliability, or requiring special attention and strict control during production and service steps. Applicants have also discovered that existing devices are limited in their ability to be mounted in a vertical orientation. In fact, the heat generated by the 'lights can cause the hot air flow along the lamp' to cause overheating of the cross-domain components and other connected components. Applicants have also found that the acceptable volume and production cost are very high, especially when the specific requirements for the use of several lamps involving the distribution of the center-center point are to be met. — C 明 】 The potential technical task of the present invention is to conceive a radiant heating device capable of overcoming the above-mentioned drawbacks. In particular, the object of the present invention is to provide a light-radiating heating device comprising: a support structure for holding a cavity; at least one of the lamps has at least two electrically connected terminals accommodated in the at least one holding cavity (10) and extends outside the holding cavity along a geometrically extending axis a radiating portion, at least one elastic supporting member, said at least one elastic supporting member engaging with the supporting structure and looking for a new shaft, (4) elastically coupling the lamp to the supporting structure and closing the holding chamber; Characterized in that the electrical connection terminals are spaced apart from each other with a spacing D that is less than a linear extension of the radiating portion of the lamp detected along the geometrically extending axis. The electrical connection terminals are thus placed closer together The position does not impair the linear extension of the lamp that is strictly associated with the radiated power. The overall structure of the device is thus greatly simplified. In particular, it can be 5 201103355 Limits the number of components required to achieve insulation of electrical components from the external environment, thus having advantages in terms of production cost and reliability. It also achieves a significant reduction in bulk size of the device without reducing heating efficiency. The device may be placed in a vertical orientation while maintaining the cavity at the bottom without the risk of overheating the components that are operatively located near the lamp terminals. Furthermore, the radiant heating of a plurality of lamps having different distributions around a central support structure is produced. The device becomes easy to meet specific requirements in terms of radiation intensity and distribution. Brief Description of the Drawings An illustration of an embodiment of a preferred but non-exclusive radiant heating device will now be given by way of non-limiting example, and in the accompanying drawings BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a radiant heating apparatus according to the present invention; and FIG. 2 is a cross-sectional view of the apparatus of FIG. 1 along a geometrical axis of one end of the lamp; The detail seen in Figure 2 of the enlarged scale is shown; Figure 4 is a section along line IV-IV in Figure 3 Figure 5 shows the structural design of the device according to the above view; Figure 6 shows the structural design of the first alternative embodiment of the device; Figure 7 shows a second alternative embodiment of the device Structural design of the preferred embodiment of the preferred embodiment 6 201103355 Referring to the drawings, a radiant heating device according to the invention is generally indicated by the reference numeral 1. The device 1 comprises a support structure 2 having a box-shaped body 3, The box body 3 preferably comprises a base 4 which, after being inserted into the sealing member 5a, is coupled to the closure cap to define at least one holding cavity 6. The bracket 7 can be joined to the holding cavity 6 to secure the ejection device 1 To a column (not shown), a wall or other support structure, such as a base 7a placed on the ground. If required, the device can be mounted in the vertical direction while keeping the cavity 6 at the bottom, for example Figure 5 shows. At least one lamp 8 is operatively coupled to the support structure 2, and the lamp 8 preferably includes a tubular outer casing 9 extending along the geometrically extending axis X. The tubular outer casing 9 is preferably made of fused silica or other radiation permeable to the lamp 8, high temperature resistant and preferably also resistant to strong and sudden changes in temperature caused by, for example, water spray or splashing water. . The tubular outer casing 9 houses at least one incandescent filament 10, preferably a carbon or tungsten filament, extending parallel to the geometrical extension axis X and electrically connected between the first and second electrical connection terminals 11. Preferably, the incandescent filament 10 extends over the length of the linear extension of the tubular outer casing 9 at the radiating portion of the lamp 8. The electrical connection terminals 11 are connected to the incandescent filaments 1 by means of respective connecting filaments 12, which are housed in at least one, preferably two, respective ends 8b of the lamps 8, said ends 8b being located at an extension of the radiating portions 8a In the ministry. Each of the connecting filaments 12 has an extended length of at least 25 mm', e.g., 75 mm, preferably no more than 100 mm' to maintain a satisfactory dimensional compactness, and the connecting filament 12 is formed of a 7201103355 conductor having a significantly lower electrical resistance than the incandescent filament 10. In this manner, by the amount of enthalpy produced by the incandescent filament 10, the end 8b of the lamp 8 can be maintained during operation - a temperature which is significantly lower than the operating temperature reached by the radiant portion 8a of the lamp 8 . The power connection terminal 11 is intended to protect her, and other suitable devices (not shown) for the battery source 13 are provided in the holding cavity 6, and the power cable passes through the holding cavity 6. The closure cap 5 is joined by a tightly sealed guide (four) Ha. It is provided that the switch 5 is connected to the sealing cap 8 through the closing cap 5 and electrically connected between the power supply line 13 and the lamp 8 in the holding chamber 8. Switch 14 is preferably of a waterproof type and/or is conveniently protected by a sealing device to prevent penetration of dust and water. The mechanical connection of the lamp 8 and the support structure 2 is obtained by at least one resilient, preferably one-piece, support member 15, which is made of a heat resistant elastomeric material, such as silicone rubber. The resilient support member 15 is engaged with the support structure 2 and sealingly mounted around the lamp 8 to elastically couple the latter to the support structure 2 and preferably to close the retaining cavity 6 in a gas-tight manner. In more detail, in the illustrated example, each end 8b of the lamp 8 is sealingly mounted by a respective resilient support member 15 which is in close contact with a through opening 16 provided in the base 4 of the box-shaped body 3. Sealed joint. For this purpose, each elastic support element 15 may advantageously comprise an inner tubular portion 17 and an outer tubular portion 18 which are concentrically arranged to each other and connected to each other in the vicinity of the end edge 15a located outside the retaining chamber 6, where it is 'elastically The support member 15 has a tapered portion having a frustoconical structure that diverges toward the retaining chamber 6. An annular seat is defined between the inner tubular portion π and the outer tubular portion 18, the annular seat being easily engaged with a support ring 19 by a tight fit σ at the shaft 8 201103355, the support ring being held around each of the throughways The through-opening σ 16 of the cavity itself protrudes outward from the holding cavity 6. It is then fitted with an inner tubular portion 17 around the respective end 8b of the lamp 8 to fit the mounted per-heap component #1, which is adapted to be mounted on the branch ring η such that the outer tubular portion 18 contributes to the corresponding through opening 16 Hermetic seal. Advantageously, more than two axial ribs 2〇 may be distributed circumferentially on the outer surface of the inner portion 17 . In more detail, in the illustrated example, the inner f-shaped portion 17 of each resilient support member 15 is provided with two axial ribs 20 located in a lamp 8 comprising the geometric extension axis X described above. The horizontal planes are orthogonal to each other in the diametrical relative position of the plane. Due to the presence of the axial ribs 20, the interference of the inner tubular portion 17 and the support ring a occurs on a relatively reduced surface, so that the end of the lamp 8 mounted on the respective resilient branch member 15 can be simply fixed. The through opening 16 in the ring 19 is mounted. When the city is completed, the compressed ribs 2 在 between the cutting object and the inner tubular portion 17 mounted on the lamp 8 ensure the upper 8 (four) support structure 2_ in any case, and for this purpose No further joining elements are required. A possible alternative embodiment (not shown) can be expected to replace the axial rib 2G after the resilient support member 15 on the end 48b of the lamp 8 has been mounted on the fulcrum ring itself. It is joined between the support ring 19 and the inner tubular portion π by a tight fit. σ When the assembly is completed, the light-emitting portion Sa of the lamp 8 extends outside the holding cavity G, and between the elastic slings, the slinging element is provided with the corresponding electrical connection terminal η in the cavity of the 201103355 Advantageously, the end portions 8b are electrically connected to each other by a distance less than a (four) extension length, the line=degree along the geometric extension axis X being able to be ==:=r'"line- (4) Line 2 is possible as in the 5th and 6th rounds of _^=^objects' or by the required line extensions, which are adapted to the different requirements related to light: quantity and knife cloth, The electrical connection terminal U is maintained in the vicinity of the position L, and the electrical connection terminal is intended to be mounted in the same holding cavity 6 or the phase cavity defined by the same box-shaped body 3, thus realizing the light-emitting device - An important structural simplification, while the overall bulk size of the device is also greatly reduced. In particular, compared with the prior art, the number of components required to achieve the sealed insulated electrical connection terminal u is reduced and the design material is The number of components of the wire 13 is reduced. In particular, in the same holding cavity 6 It is possible to place all the electrical connections, which is advantageous for the reliability in terms of sealing and structural simplification. The arrangement of the electrical connection terminals 11 in the same box body 3 allows the radiant heating device 1 having a vertically extending portion It is manufactured that the device is also suitable for placement on the ground, such as the example in Figure 5, without the risk of elastic support members 15 and/or electrical components being overheated. In fact, standing on the lamp 8 The elastic support element 15 on the box-shaped support 3 is not swept by the hot air flow rising along the lamp 8 itself and the guard partition 24. 201103355 The one or more holding chambers housed in the same box body 3 may be surrounded by the box The electrical terminals of the lamps distributed by the body itself are shown in the examples in Figures 5 and 6. Preferably, from Figures 1 and 2, the device 1 may further comprise at least one parabolic mirror 21 resembling a half-shell. It accommodates the radiating portion 8a of the lamp 8 in its cavity. The parabolic mirror 21, for example made of a press plate, preferably has a tight fit with the coupling groove 22 defined in the support structure 2. Attach 21a. Preferably, the sealing member 23 made of a thermally insulating material accommodated in the coupling groove 22 holds the parabolic mirror 21 by friction to ensure its stability. Advantageously, the parabolic mirror 21 can be combined with the elastic support. The protective partition 24 is passed around the element 15 by the radiating portion 8a of the lamp 8. The protective partition 24 is oriented in a direction inclined with respect to the geometrically extending axis X of the lamp 8, conveniently protecting the resilient support member 15 from operation of the lamp 8. The radiation is radiated so as to avoid overheating. Further combined with the support structure 2 may be a protective casing 25 extending over the continuation of the box-shaped body 3 to accommodate the lamp and the parabolic mirror 21.
