The main fuel tank (24) is compatible with various remotely controlled or manually adjustable combustion units coupled.

Description

The invention relates to a two-component lamp with a light source operated with liquid fuel, in which the upper part of the lamp is advantageously designed with a rod wick for the controlled combustion of the liquid fuel, and the lower part as a fuel storage tank also with a rod wick or is designed in a simpler tank design with a wick that is otherwise customary, with both lamp parts, the combustion unit and the fuel storage tank, being firmly connected to one another by a holding mechanism, for example by a thread or quick-release fastener, for functional execution and both the rod wick from the combustion unit as well as the wick of the fuel storage tank are equipped with fuel transfer contact surfaces, with at least one of the two contact surfaces having a contact pressure spring which exerts a contact pressure on the two contacts lying one on top of the other t surfaces ensures a safe flow of fuel and, depending on the type of design, the fuel storage tank is equipped with a rod wick and fuel level control valve for even saturation of the wick and with a pressure spring for the fuel transfer surface to the combustion unit, as well as in a simpler version a common wick, for example made of cotton, with a firmly anchored fuel transfer surface is functionally equipped, in which the contact pressure is exerted by the pressure spring of the rod wick from the combustion unit. This functionality is similar to a stamp pad, in which a liquid enriched with dyes is transferred to another medium via contact surfaces. According to this mechanism of the two contact surfaces, the transferring transport of liquid fuel in lights with a divided wick through a fuel storage tank that can be used once, and a very high-quality, controllable combustion unit that can be used again and again, also works. In practice, the use of camping gas cartridges is comparatively widespread, with which fuel is made available in a universal storage container for a variety of uses with compatible attachments, ranging from blowtorches and cooking appliances to lighting fixtures.

the AT 513 817 B1 discloses a lamp serving as a grave lamp with a light source operated with liquid fuel, the wick of which opens at one end into a fuel reservoir and at the other end into a combustion chamber, with a main tank being provided for the fuel, which is connected to the fuel reservoir, with the fuel reservoir having a level control valve for assigned to the fuel flowing into the fuel store. The wick is designed as a stick wick. Furthermore, a flame throttling sleeve that is adjustable in height relative to the wick is provided, which releases an adjustable combustion surface of the fixedly anchored wick

the DE 10 2018 103 703 B3 discloses a lamp with a movable rod wick with a light source operated with liquid fuel, the wick of which opens out into a fuel reservoir at one end and into a combustion chamber at the other end, a main tank being provided for the fuel which is connected to the fuel reservoir, with the fuel reservoir having a level control valve assigned to the fuel flowing into the fuel store. The wick is constructed as a threaded rod wick that is partially moisture insulated on its surface. Furthermore, wings are attached to the rod wick like a wing screw, with the help of which the rod wick can be screwed out of a nut thread up to a calibration mark and then a flame throttling sleeve can be screwed on via the housing screw thread into an adjustable operating position, thus releasing a combustion surface related to the burning time scale.

Furthermore, the DE 10 2018 103 700 B3 Ignition mechanisms for rod wicks, in which the wick evaporator head is heated by a heating coil towards the fuel evaporator and ignition pins start the flame formation.

The invention is based on the object of creating a lamp of the type mentioned at the outset, which has an additional functionality in which both a lamp with a lamp attachment to be put into operation manually and with an operating time that can be determined in advance can be controlled by an exchangeable fuel storage tank, as well as by an easy-to-manage remote ignition, for example via a smartphone, a lamp that can be operated and controlled safely over a long distance without supervision and by the exchangeable lamp components, a consumable and inexpensive fuel storage tank on the one hand, and a high-quality and controllable one that can be used again and again Combustion unit on the other hand, enable a safe, ecologically advantageous and cost-effective operation of the lights.

The object is achieved according to the invention by the features of claim 1.

A lamp operated with liquid fuel is divided into two lamp components, with each individual lamp part having its own dedicated wick to accomplish its function, so that the lamp consists of two separate wick parts, which manage the fuel transport via wick contact surfaces for overflowing the liquid fuel on a contact plane. The two wick parts can, but do not have to, be made of one and the same material, so that different material properties can be used for each required functional task, which are specially adapted to the requirements and have different quality features and pricing. On the one hand, this enables optimal adaptation to the requirements of its functionality, taking into account the necessary costs, on the other hand, environmental criteria can be taken into account for the lamp consumable parts such as the fuel storage tank, so that harmonious materials management can be achieved.

For example, a very high-quality wick material is used for the combustion part, which can be controlled both manually and remotely, which mostly consists of a rod wick and should be retained for many operating cycles. Due to its almost wear-free and unchangeable size and quality, it enables very precise control processes, which are a fundamental feature of the lamp and should show the advantages over existing lamps. In addition to the ease of use, this should create a price/performance ratio that is hardly possible anywhere else. When it comes to the composition of the wick in the fuel tank compartment, you have the option of using previous, very inexpensive materials such as cotton, which can be recycled after it has been used once, or higher-quality materials such as a rod wick, which also has an additional function as a shut-off valve for the fuel inflow and the ambient air supply in the tank room can be used. A more extensive production variety is thus offered, which is intended to make production companies more flexible in the manufacture of luminaires and to enable more different types of execution and pricing.

In the case of the fuel storage tank, one can distinguish between two different construction models, according to which the controllable combustion part must also be aligned and adapted. In the higher-quality fuel storage tank with a rod wick, when docking with the controllable combustion part, the rod wick with its tank wick fuel transfer surface is pressed by a tank valve spring against the wick fuel transfer surface of the controllable combustion part, thus establishing the fuel flow. In the case of certain types of lights with continuous mobility of the two rod wick parts of the combustion unit and fuel storage tank, the fuel inflow at the tank bottom can be completely closed by the rod wick in the fuel storage tank via the control unit of the combustion part, and in this way the light can be taken out of service for later, renewed commissioning and operating times. When the screw-on tank cap is screwed on, the rod wick is also pushed completely into the wick insertion space and the fuel supply valve to the rod wick is thus closed, which has handling advantages for storage and transport as well as for clean tank disposal. In certain lamp designs, the rod wick is immovably mounted in a closed control system of the lamp's combustion unit, as a result of which an operational, factory calibration of the time-controllable flame throttling sleeve has already been carried out.

In the simpler main fuel tank design, the commercially available wick and the tank wick fuel transfer surface are immovably and firmly mounted, so that the adjusted docking pressure on the wick fuel transfer surfaces must come via a flame throttling sleeve spring of the combustion unit, which requires subsequent calibration of the flame throttling sleeve according to a calibration mark or a calibration bar during manual light commissioning, or also made necessary by a resistance-triggering calibration bar during the remote-controlled commissioning of the lamp and must be carried out before the lamp is commissioned.

When starting up the lamp manually, the flame throttling sleeve is screwed onto the fuel tank thread with the burn time indicator on the dial until a calibration mark appears on the rod wick, which must be at the same height as the flame throttling sleeve opening. At the same time, the flame throttling sleeve spring pushes the wick fuel transfer surface onto the tank wick fuel transfer surface, allowing fuel flow, which also initiates air delivery into the fuel storage tank via an air delivery passage. For example, the default calibration mark is factory affixed to a stick wick site for 20 days of service. The burn time dial in the burn time dial rail is then shifted in its numerical display until the burn time dial hand is exactly over the 20-day burn time dial display. In a In the second calibration option, the flame throttling sleeve is screwed onto the fuel tank thread until the flame throttling sleeve comes to rest on a calibration bar of the rod wick or plastic wick body, a resistance is triggered and the largest possible wick combustion surface is exposed, which has been calibrated by the manufacturing plant, for example, to 6 operating days. The burn time dial is then moved in the burn time dial rail until the 6th day of operation is located exactly under the burn time dial pointer. This also completes this calibration and any desired day setting can be made with the burn time indicator on the burn time indicator, but without exceeding the "STOP" marking.

For the remote-controlled commissioning of the light, the flame throttling sleeve is screwed onto the thread by the geared motor until the calibration bar triggers a resistance on the flame throttling sleeve and no further screwing is possible. Thus, from the flame throttling sleeve, the largest wick combustion surface with, for example, 6 days of work calibration setting is exposed and can be taken over by the flame throttling measurement sensor, so that the ignition mechanism can take place by heating the heating coil and subsequent ignition spark. After the ignition process has been successfully controlled by an infrared sensor, any desired day setting can be made via the flame throttling measuring sensor and triggered light pulses from the flame throttling sleeve gear. The lamp is switched off by completely retracting the flame throttling sleeve beyond the rod wick, which causes the flame to go out.

For storage and transportation of the fuel storage tank, a peel seal film is adhered over the tank wick fuel transfer surface which must be peeled off prior to screwing on the controllable combustion unit. A screw-on tank cap with a sealing ring is provided for disposal of the empty fuel tank.

The combination of a high-quality, controllable combustion unit made of the best materials, which can be used over and over again, and a fuel storage tank that has to be manufactured in large numbers and that can be recycled after its one-time use or returned for refilling, gives the luminaire manufacturer the opportunity to remain in business contact with a satisfied consumer, in which he always produces high-quality and yet inexpensive fuel for the subsequent purchase of a filled main fuel tank, which, with regard to the geographical location of the lighting application and the local climatic conditions, is the most suitable fuel for a safe and offers the best possible time-controlled operation.

Due to the very compact design with, where necessary, very high-quality materials, accidents can be almost completely ruled out. Contamination of the lamp stand surfaces, as can be observed again and again in practice due to leaking fuel in the form of liquid wax, should not occur with the stable liquid fuel storage tank, provided that it is used within the framework of the specified instructions for use. In addition to fulfilling a priority safety factor, the lamp also offers unique ease of use, which means that in our environmentally conscious age important ecological aspirations can be met by using energy in a very targeted manner with high efficiency.

The dependent claims represent advantageous developments of the invention.

In a first variant of the present light, the main fuel tank contains a rod wick which is equipped with a tank wick fuel transfer surface which is pushed out of the main fuel tank by a tank valve spring up to a tank valve spring end stop. When unscrewing the manual or remote-controlled lamp combustion unit, the firmly anchored rod wick is brought into contact with its wick fuel transfer surface with the tank wick fuel transfer surface and thus establishes the inflow of liquid fuel to the combustion unit. In the case of the remote-controlled lamp, the rod wick firmly anchored in the combustion unit has already been calibrated by the manufacturing plant with the flame throttling sleeve, so that after the main fuel tank and combustion unit have been screwed together, the desired flame size and operating time can be set independently of one another, for example using a smartphone. In the case of the combustion unit with a movable rod wick that is to be started up manually, the flame throttling sleeve must be matched to the combustion duration dial in a calibration process before the ignition process.

In a second variant, a simpler and immovable main fuel tank design, the wick is made of a conventional material such as cotton, which is fixed and immovable with its tank wick fuel transfer surface anchored to the main fuel tank. The wick is supported to the bottom of the main fuel tank with a rod or in a straight line pipe, so that the laser mirror floating ring can easily sink to the bottom of the main fuel tank without resistance when consuming fuel. Only at the bottom of the main fuel tank does the wick separate into several individual parts so that the fuel can be absorbed as completely as possible. In the tank wick fuel transfer surface and partially in the wick there is an air supply duct which extends into the interior of the fuel tank and which, through the inflow of ambient air, compensates for the negative pressure produced by the consumed fuel in the interior of the tank.

In this second variant with a firmly anchored and immovable tank wick fuel transfer surface, a rod wick that can be moved in the combustion unit, with a flame throttling sleeve spring, must produce the stable contact from the wick fuel transfer surface to the tank wick fuel transfer surface for the overflow of fuel to the rod wick. Slight differences in height of the tank wick fuel transfer surface result in different height positions of the rod wick when the flame throttling sleeve spring is pressed, so that the rod wick and flame throttling sleeve must be calibrated before the lamp is put into operation.

When the lamp is started up manually, there is a calibration mark or a calibration bar on the wick. The flame throttling sleeve with burn time dial pointer is screwed onto the fuel tank thread until the opening of the flame throttling sleeve and the calibration mark on the rod wick are at the same height. This exposed wick surface could, for example, have been calibrated at the factory for 20 operating days, so that the burning time dial in the burning time dial rail is moved so far until the burning time dial pointer on the flame throttling sleeve and the 20 operating day display on the burning time dial are on top of each other. This calibration process is also possible with a calibration bar, on which the flame throttling sleeve comes to rest by screwing down and thus the largest possible wick combustion surface is exposed, which has been calibrated by the manufacturing plant for 6 operating life days, for example. The burn time dial is then moved along the burn time dial rail until the 6 operating days display on the burn time dial is under the burn time dial pointer. This completes the calibration process and any desired operating time can be set across the entire burn time dial using the burn time dial hand, but without exceeding the “STOP” mark on the burn time dial with the burn time dial hand.

When the lamp is started up by remote control, the rod wick is provided with a calibration resistor at one point, for example with a calibration bar. After screwing together the two lamp components, combustion unit and main fuel tank, the flame throttling sleeve is driven into the rod wick by a triggering radio command from the geared motor until the calibration bar on the rod wick triggers a resistance on the rotating flame throttling sleeve and comes to a standstill. This exposes the largest possible wick burning surface calibrated by the manufacturing plant to, for example, 6 days of operation. A calibrated reference meter point is thus transmitted for an installed measuring device, which is transmitted, for example, as in the drawings cited, by a flame throttling measuring sensor in an electronic flame throttling counter. Any desired flame size can be set by means of a pulse counter through the flame throttling sleeve gear wheel and the light-controlled flame throttling measuring sensor, and the flame can also be extinguished by completely retracting the flame throttling sleeve beyond the rod wick, thus ending a predetermined operating time. An infrared sensor installed on the control unit and aimed at the flame monitors the operating instructions of the control electronics.

In order to be able to obtain information about the current fuel supply during a remote query, a laser fuel level gauge is installed in the control unit, which sends its light beam through a transparent laser window onto a laser mirror floating ring floating in the interior of the main fuel tank, which is then reflected back to a receiver and, for example, this data transmits to the display monitor of a smartphone using a corresponding app. This app not only forwards desired operating settings over long distances, but also transmits operating data as feedback, as calculated by the on-board computer and provides information about the fuel content in the tank, remaining operating times with average fuel consumption and much more. Photovoltaic panels on the top and outside of the control unit supply the rechargeable batteries with sufficient power to control the light.

Since the control unit, which is made from the best materials and is equipped with the highest quality technology, only has to be purchased once and can be coupled again and again to the main fuel tanks, which can be produced easily and very inexpensively, the operating hour prices are very favorable, which also ensure a very high level of operational reliability of the light and a Offer ease of use of the light, which enable an ecologically sensible and effective lighting design in a user-friendly way. The connectable main fuel tanks not only offer their use in remote-controlled radio-operated lights, but can also be put into operation manually with a very simple flame throttling sleeve attachment, with which, depending on a burning time dial, up to very long operating times with different luminosity radiation can be selected and a very high level of operational reliability is also guaranteed.

Die Kontaktherstellung für den Brennstofffluss von der Tankdochtbrennstoffübertragungsfläche zur Dochtbrennstoffüberleitungsfläche braucht bei dieser Brennstoffhaupttankbauweise nicht mehr über eine Andruckfeder erfolgen, sondern wird durch die natürliche Ausdehnung des elastischen Werkstoff der Tankdochtbrennstoffübertragungsfläche bewerkstelligt.

• 5 a cross-section of a lamp design with a rod wick lifting mechanism through motor gears engaging on rod wick toothed grooves, which have retracted the partially moisture-insulated rod wick completely into the flame throttling sleeve with heating coil and thus cause the smallest wick evaporator head surface, and at the same time have pushed the partially moisture-insulated rod wick completely into the wick insertion space and thus the fuel flow in the fuel supply valve as well as the air supply duct in the main fuel tank have closed, whereby the operating flame is extinguished, and an infrared sensor for operational safety monitors the functional process.
• 6 a cross-section of a lamp design with a rod wick lifting mechanism with a partially coated rod wick, which is anchored with a rod wick insertion fixation in a plastic wick body serving as a support element, in whose applied rod wick toothed grooves motor gears engage, in a wick evaporator head surface position that is as far as possible released with adjacent heating coil and flame ignition pins, operation-monitoring infrared sensor, and in the The main fuel tank has a fuel supply valve and air supply channel, which is wide open due to the pressure effect of the tank valve spring, and a slim rod wick that is raised to the tank valve spring end stop and partially embedded in a plastic wick body for support and moisture insulation.

• 8th Figure 12 is a cross-section of a lamp with lamp cover having a manually adjustable combustion unit with the movable combustion rod wick making fuel flow contact between the tank wick fuel transfer surface and the wick fuel transfer surface with a weaker flame choking sleeve spring in a wick guide tube against the tank rod wick having a stronger tank valve spring and pushed to the tank valve spring end stop. At the same time, the fuel supply valve and the air supply channel in the main fuel tank are opened by the stronger tank valve spring. The rod wick of the combustion unit has a calibration mark, which is calibrated by the manufacturer for 20 operating days, for example, so that to put the lamp into operation, the flame choke sleeve is screwed onto the fuel tank thread until the flame choke opening is level with the calibration mark and then the fuel dial is in the Fuel dial track on the 20 day burn time dial indicator with the burn time dial hand in the same superimposed position. A calibration procedure is also possible in which the length of the wick guide tube has been determined by the manufacturing plant to a calibrated dimension so that when the flame throttling sleeve is screwed onto the fuel tank thread the wick guide tube slides back on the rod wick until the lower wick guide opening is on the cone of the top of the wick fuel transfer surface rests and releases the largest possible calibrated wick burning surface. The burn time dial is then pushed under the burn time dial hand with the smallest operating time day display. The combustion time dial is thus matched to the flame throttling sleeve and the combustion time dial pointer can be used to set any operating time on the fixed combustion time dial, but without exceeding the “STOP” mark with the combustion time dial hand. The figure shows the smallest stick wick burning surface.
• 9 a cross section of a lamp with lamp cover with a manually adjustable combustion unit, with the movable combustion rod wick fixed in a plastic wick body and with a weaker flame choking sleeve spring in a wick guide tube against the tank rod wick, which has a stronger tank valve spring, when screwing together the lamp components the fuel contact between the tank wick fuel transfer surface and which produces wick fuel transition area. At the same time, the fuel supply valve and the air supply channel in the main fuel tank are opened by the stronger tank valve spring. The flame choke sleeve is screwed further and further onto the fuel tank thread with the flame choke sleeve thread and the stronger tank valve spring compresses the weaker flame choke sleeve spring more and more. In doing so, the wick guide tube with the flame choking sleeve is guided back more and more on the rod wick, whereby the opening of the flame choking sleeve releases an ever-increasing wick combustion surface until the flame choking sleeve comes to rest on the calibration bar of the plastic wick body, and also the lower opening of the wick guide tube on the cone on the top the wick fuel transfer surface comes to rest, so that the largest possible wick combustion surface is at this end point has become free, which has been calibrated by the manufacturing company, for example, to 6 operating days. To adjust the burn time dial, this is moved in the burn time dial rail until the 6-day operating time display is exactly below the burn time dial hand. This completes the calibration process and any operating time can be set on the burning time dial for the subsequent operating time setting, but the “STOP” marking on the burning time dial may no longer be exceeded. By enclosing the rod wick with a plastic wick body, the mass of the rod wick is kept as low as possible, which means that the wick saturates more quickly when it is put into operation and that it is taken out of operation more quickly, which is an advantage with specially time-controlled, remote-controlled lights.
• 10 a cross section of a lamp with separate lamp cover and a manually adjustable, separate combustion unit with a movable combustion rod wick and the flame choke sleeve screwed in the lamp cover. The main fuel tank, which is also used for remote-controlled lights in its design, is equipped with a screw-on tank cap, which is screwed onto the fuel tank thread and the sealing ring rests on the tank valve spring end stop for sealing, and the tank valve spring is compressed so far that the inserted tank rod wick also Fuel supply valve and the air supply channel closes on two sealing rings. Alternatively, a screw-on tank cap is also shown, which is screwed onto both the fuel tank thread and the housing screw thread and the cover surface has a wavy shape in order to adequately compensate for any stresses that arise on the screw-on tank cap between the two screw-on threads.
• 11 a plan view of the light's main fuel tank, which is of a design suitable for both the remote controlled light and manually adjustable burn time and start-up, showing the tank wick fuel transfer surface in the center, surrounded by the fuel tank thread, the laser transmission window and then the burn time dial in the Burn time dial rail and finally on the outside the description and operating instructions.
• 12a a top view of the burn time dial, which is stamped and printed approximately from a moisture-resistant cardboard, which is provided with a pressed waveform on the outer edges, in order to prevent unintentional shifting of the calibration-tuned position of the burn time dial during burn time adjustment with the flame throttling sleeve by means of an adapted movement resistance in the burn time dial rail and the burn time dial pointer to the daily run time display of the burn time dial.
• 12b a top view of the main fuel tank, on which the combustion unit for the lamp to be manually operated is screwed. The calibration procedure is shown, in which the flame throttling sleeve is screwed onto the fuel tank thread until the opening of the wick guide tube is level with the calibration mark on the rod wick, as shown in FIG 13 indicates. The wick combustion surface, calibrated and marked by the manufacturing plant for example to 20 operating life days, is then transferred to the operating time dial by sliding the operating time dial in the operating time dial rail until the 20 operating time dial day indicator is located under the operating time dial pointer. If the burn time dial is adjusted to the wick combustion surface calibrated by the manufacturer via a calibration bar, then the flame throttling sleeve is screwed onto the fuel tank thread until the flame throttling sleeve rests on the calibration bar of the rod wick and thus has the largest possible wick combustion surface and the shortest burning time, whereupon the the burn time dial is shifted in the burn time dial rail until the 6 operating time day display is under the burn time dial hand. This completes the calibration process and any day setting can be made without exceeding the "STOP" mark on the burn time dial with the burn time hand. When using the main fuel tank for manual start-up and operating time setting, the laser passage window on the main fuel tank does not have to fulfill any functional task.
• 13 a cross-section of the lamp with lamp cover in a simpler design of the main fuel tank with an immovable tank wick fuel transfer surface and commercial wick, with a manually adjustable flam ment control unit in the calibration position with the flame throttling sleeve opening level with the calibration mark and exposing that wick combustion surface area which has been calibrated and dated on the burn time dial by the manufacturing plant and then the burn time dial in the burn time dial rail with the burn time dial and the calibrated day number Burn time dial hands must be pushed into the superimposed position and the calibration process is thus completed. To set the operating time, any desired combustion time can be set on the combustion time dial using the flame throttling sleeve and the combustion time dial pointer located on it, but without exceeding the "stop" marking on the combustion time dial. The flame throttling sleeve spring presses the wick fuel transfer surface of the movable rod wick onto the stationary tank wick fuel transfer surface, which draws fuel via a commercial wick, which is rod and/or tube supported for stability and partially fitted with an integral air supply duct.
• 14 a cross-section of the lamp with lamp cover and its own combustion unit screwed onto the main fuel tank, in which a rod wick adjusted to the largest possible combustion surface is anchored immovably with a rod wick insert fixation in a plastic wick body with air supply duct and in a closed system the flame throttling sleeve with combustion duration dial pointer already from the manufacturing plant to the firm mounted burn time dial has been calibrated. The tank wick fuel transfer surface in the main fuel tank consists of an elastic, absorbent material which draws the fuel from the tank space via a commercially available wick material with a wick support rod and/or wick support tube and integrated air supply channel. In this main fuel tank design, the fuel flow from the tank wick fuel transfer surface to the wick fuel transfer surface no longer needs to be brought into contact with a pressure spring, but rather is accomplished by the natural expansion of the elastic material of the tank wick fuel transfer surface.
• 15 a cross-section of the lamp with lamp cover with a remote-controlled combustion unit with a partially coated rod wick that can be moved in a guide tube with a flame throttling sleeve spring and is equipped with a heating coil and flame ignition pins, with a wick evaporator head surface set to the smallest possible size, which has a calibration bar or also a calibration hollow truncated cone, which is used for the calibration process of the flame throttling sleeve in the model shown, an adjustment movement tolerance of the rod wick to the permanently mounted tank wick fuel transfer surface of up to plus/minus 2 millimeters is left free. A flame choke gauge sensor counts the light pulses from the flame choke sleeve gear for flame size control and a laser beam from a laser fuel gauge shown in the drawing is projected through a laser transmission window onto the laser reflecting floating ring in the main fuel tank and reflected back to the laser fuel gauge so that the resulting time delay shows the current fuel level can calculate which is still available for further operation.
• 16 a cross-section of the lamp with lamp cover with a remote-controlled combustion unit with a partially coated rod wick that can be moved in a guide tube with a flame throttling sleeve spring and is equipped with a heating coil and flame ignition pins, with a wick evaporator head surface set to the largest possible size, which has a calibration bar or also a calibration hollow truncated cone, which is used for the calibration process of the flame throttling sleeve in the model shown, an adjustment movement tolerance of the rod wick to the permanently mounted tank wick fuel transfer surface of up to plus/minus 2 millimeters is left free. For the calibration process, the flame throttling sleeve is screwed onto the thread by the geared motor until it rests on the calibration bar or calibration hollow cone and the geared motor switches off due to the resistance triggered. This exposes the largest possible wick combustion surface, which is calibrated by the manufacturing plant, for example, to an operating time of 6 days. A flame choke meter sensor takes over this position and counts the light pulses from the flame choke sleeve gear for further flame size control. If necessary, a laser fuel gauge calculates the current fuel level with a light beam via a reflecting laser mirror floating ring.
• 17 a cross-section of the lamp with lamp cover with a remote-controlled combustion unit with a movable rod wick and with a heating coil mounted on the wick guide tube and ignition pins fixed on the top of the control unit so that no electrical components are processed in the rod wick, with a wick combustion surface set to the smallest possible size. The power transmission line for the heating coil runs on the wick guide tube. The position of the calibration beam, which can move in a free gap of the wick guide tube, allows an overlying height difference when components are screwed together as a connection tolerance of the wick fuel transfer surface to the tank wick fuel transfer surface of up to plus/minus 2 millimeters and is adjusted by the flame choke sleeve spring on the wick guide tube to the rod wick. An infrared sensor controls the ignition process and monitors the current operating status. A light-controlled flame choke gauge sensor counts pulses from the flame choke sleeve gear for flame size control and a laser fuel gauge uses a reflective laser mirror floating ring in the main fuel tank to calculate the actual fuel level from the resulting time delay. The fixed tank wick fuel transfer surface is supplied with liquid fuel via a rod supported commercial wick with an integral air supply duct. An infrared sensor controls the ignition process and monitors the presence of a flame over the entire operating time. In the drawings of 17 , 18 and 19 a second possibility of power transmission from the geared motor to the flame throttling sleeve gear is shown.
• 18 a cross-section of a lamp with lamp cover with a remote-controlled combustion unit with a movable and with a heating coil mounted on the wick guide tube and ignition pins fixed on the top of the control unit so that the wick contains no electrical components, with a combustion surface set to the largest possible. The illustration shows the calibration process, in which the flame throttling sleeve is screwed onto the thread of the control unit until the calibration bar triggers a resistance on the flame throttling sleeve and comes to rest. The largest possible approved wick combustion surface has thus been reached and was calibrated by the manufacturing plant, for example, to 6 operating days. This position adjustment is taken over by the flame choke measuring sensor and can thereafter subsequently set any selected flame size via the light pulse count from the flame choke sleeve gear. The flame throttling sleeve spring presses the rod wick with wick fuel transfer surface in the wick guide tube against the permanently mounted tank wick fuel transfer surface and allows a height difference of plus/minus 2 millimeters for the calibration process. The ignition process and the ongoing operating status are monitored by an infrared sensor.
• 19 a cross-section of a lamp with a separate lamp cover and a separate, remote-controlled combustion unit with a movable, partially coated rod wick and a heating coil mounted on the wick guide tube, and ignition pins attached to the top of the control unit, the rod wick containing no electrical components. The flame throttling sleeve spring presses the rod wick calibration bars against the threaded end cone which prevents the rod wick from falling out of the control unit. The tank wick fuel transfer surface on the main fuel tank is sealed with a peel seal film for safe transportation and storage.
• 20 Figure 12 is a top view of a lamp showing the remote controllable combustion unit with the rod wick and flame choke sleeve in the centre, the ignition pins and the infrared sensor, and the photovoltaic panels on the control unit at the top and on the outside. A transponder firmly anchored in the vicinity of the lamp ensures that the remote-controlled lamp is local so that it can only function at its installation site.

The lamp, which is designed to be electronically remote-controlled or operated manually, consists of two compatible components that are brought together with a screw thread or other connecting device, with the main fuel tank 24 both for the remote-controllable lamp and for the manually in lamp to be operated is used so that with a tank wick fuel transfer surface 7 the fuel flow is established by contact with a wick fuel transfer surface 6 . This establishment of contact can come from a tank valve spring 14 as well as from a flame throttling sleeve spring 13 or by an absorbent, elastic material of the contact surfaces take place. The wick 56 in the main fuel tank 24 can, with different functional designs, consist of a rod wick 1, which is also used mechanically with a tank valve spring 14 and a tank valve spring end stop 16 as a fuel inflow valve 28 and at the same time controls the air supply duct 17 in the main fuel tank with the movement of the wick. In an intermediate fuel reservoir 25, a level control valve 26 ensures that the fuel flows evenly from the rod wick 1 to the uncoated wick surface 4 in order to avoid greater pressure differences when the main fuel tank 24 is full or almost empty and thus to achieve an always even saturation of the wick, which ensures that the specified and calibrated service life.

A level control valve 26 for the fuel flowing into the fuel buffer store 25 is assigned to the fuel buffer store 25 for uniform fuel processing, with the main fuel tank 24 being sealed off in a gas-tight manner and the fuel buffer store 25 being connected to the ambient air via an air supply duct 17. The liquid fuel can flow from the main fuel tank 24 into the intermediate fuel tank 25 until the liquid level in the intermediate fuel tank 25 completely closes off the inflow opening of the level control valve 26, and thus a return flow of air from the intermediate fuel tank 25 into the main fuel tank 24 via the inflow opening of the level control valve 26 and the intermediate fuel store 25 is prevented. If the fuel level in the intermediate fuel store 25 falls below the upper edge of the inflow opening of the level control valve 26, which opens into the intermediate fuel store 25, air can flow out of the intermediate fuel store 25 through the inflow opening of the level control valve 26 via the intermediate fuel store 25 into the main fuel tank 24, so that fuel can flow into the intermediate fuel store 25 continues to flow until the liquid level in the intermediate fuel reservoir 25 is at least again at the level of the upper edge of the inflow opening of the level control valve 26 . The control function of the cone-shaped fuel supply valve 28 can also be performed by other known valve constructions used for liquid shut-off controls

Due to its stable, linear construction, the rod wick 1 ensures a high level of security for the problem-free sinking of the laser reflection floating ring 49 in the main fuel tank 24 in order to be able to determine the fuel supply in the main fuel tank 24 using a laser fuel filling meter 47 .

In another main fuel tank design, a commercially available wick material 56 supported by a rod or tube to the bottom of the tank is connected to a permanently mounted tank wick fuel transfer surface 7, which as a straight wick 56 partially integrates an air supply channel 17. On the inside of the tank bottom, this wick 56 is frayed apart in order to be able to completely absorb the liquid fuel. In order to stabilize the required, straight shape of the wick 56, it can be woven around a rod as a support body or located in a support tube, which is necessary for the proper sinking of the laser reflection floating ring 49 in the main fuel tank interior 24. The fixed tank wick fuel transfer surface 7 requires movable contacting of the fuel transfer surfaces from the combustion unit, except that the tank wick fuel transfer surface 7 is made of an absorbent and resilient material. For storage and transport, the tank wick fuel transfer surface 7 is additionally provided with a peel-off sealing foil 59 and closed with a screw-on tank cap 52 as with all other main fuel tank types. On the top of the main fuel tank 24 there is a laser passage window 48, the burn time dial 29 in the burn time dial rail 30 and the operating instructions 32. The possible, different fuel main tank designs require a design adaptation of the designs for both remotely controlled and manually controlled combustion units.

The main fuel tank 24 with a rod wick 1 can be used for the lights according to the figures 1 until 12 be used in its design both for electromechanical remote control units as well as with the hands via direct access to the flame throttling sleeve 8 in the same way. At the lamp combustion unit 1 until 4 If the rod wick 1 equipped with a heating coil 20 and flame ignition pins 21 is firmly anchored in a rod wick insert fixture 10 and the surface of the wick evaporator head 3 is released by screwing the flame choke sleeve 8 onto the flame choke sleeve thread 11 via a flame choke sleeve gear wheel 36, which is simultaneously triggered by light pulses from a flame choke measuring sensor 23 through the tooth notches of the flame choke sleeve gear 36, the flame size is controlled. Fuel flow from the tank wick fuel transfer surface 7 to the wick fuel transfer surface 6 is established by compressive action of the tank valve spring 14 which moves the rod wick 1 within the tank valve spring end stop 16 and at the same time also the Fuel supply valve 28 and the air supply channel 17 at the sealing rings 19 opens. The lamp operation is monitored by the heat-dependent current resistance of the heating coil 20, which after the active heating-up phase passively controls the current operating state by temperature detection in the control electronics 44. The operation of the lamp is terminated by the controlled flame throttling sleeve 8 surrounding the surface of the wick evaporator head 3 until the flame is extinguished.

Show in different versions 5 until 7 an electromechanical rod wick control in the form of a wick lifting and lowering mechanism, in which motor gears 37 engage in the rod wick toothed grooves 54 and release the size of the surface of the wick evaporator head 3 via a geared motor 38 . At the same time, during this transfer of movement to the rod wick 1 in the main fuel tank 24 within the stop path of the tank valve spring stop 16, the fuel inflow valve 28 and the air supply channel 17 are opened, or the pressure effect of the tank valve spring 14 made possible by a return movement of the rod wick 1 is also closed again. The heating coil 20 and the flame ignition pins 21 are outside, separate from the movable rod wick 1, fixedly mounted on the control unit top. on 6 the motor gears 37 engage in the protective wick toothed grooves 54 of a plastic wick body 2 in which the rod wick 1 is firmly anchored in a rod wick insert fixation 10 . This makes it possible to use a rod wick 1 with less inherent stability and thus less material mass, whereby faster saturation of the wick 56 designed as rod wick 1 with liquid fuel can be achieved for advantageous functioning with relatively quick start-up and a relatively short shutdown delay of the lamp.

is shown in 5 a sunken rod wick 1, which releases the smallest possible surface of the wick evaporator head 3 in the flame throttling sleeve 8 and at the same time also closes the fuel supply valve 28 and the air supply channel 17 in the main fuel tank 24, causing the flame to go out. on 6 the largest possible surface of the wick evaporator head 3 is shown reaching out from the flame throttling sleeve 8, where the wick ignition process is also initiated. The tank valve spring 14 then presses into a slender rod wick 1 embedded in a plastic wick body 2 in the main fuel tank 24 within the tank valve spring end stop 16 against the wick fuel transfer surface 6, and at the same time opens the fuel inflow valve 28 and the air supply channel 17 when it exerts pressure. An infrared sensor 55 controls the ignition process and monitors it ongoing lamp operation. A laser fuel gauge 47 sends its light beam from the control unit through a laser transmission window 48 onto the laser mirror floating ring 49 in the main fuel tank 24, and uses the reflected light beam and the resulting time delay to determine the current fuel supply in the main fuel tank 24 if necessary. 7 shows a plan view of the rod wick elevator, in which the motor gears 37 engage in the protective wick toothed grooves 54 of the rod wick 1 of the rectangular rod wick side surface. In the area of the flame throttling sleeve 8, the rod wick is again designed in a round shape. The laser fuel gauge 47 and the infrared sensor 55, as well as the control electronics 44, the power storage batteries 45 and the photovoltaic panels 46 required for their power supply on the outside of the control unit are also shown.

Just like the main fuel tank already according to the 1 until 7 is used with a rod wick 1 for the electromechanical control unit, this is shown in the figures after the 8th until 10 also used for a lamp to be operated manually or by hand, which can be set to desired operating time lengths without any electrical components in a very simple design of the combustion unit. The flame throttling sleeve thread 11 of the manually adjustable combustion unit is screwed onto the fuel tank thread 12 until the weaker flame throttling sleeve spring 13 yields to the counter-pressure of the stronger tank valve spring 14 and the flame throttling sleeve opening is guided back in the wick guide tube 9 until it is marked with the calibration mark 50 on the rod wick 1 is at the same height and the burn time indicator hand 31 thus assumes a determining position. This calibration marking 50 was calibrated by the manufacturing plant to 20, for example, with regard to the luminous operating days, so that the burn time indicator dial 29 in the burn time indicator plate rail 30 then has to be shifted until it the burning time dial hand 31 with the 20 operating day display is in the underlying position. In another possible calibration process, the wick guide tube 9 has a length calibrated by the manufacturing plant, so that by screwing down the flame choke sleeve 8, the lower flame choke sleeve opening comes to rest on the upper side of the cone of the wick fuel transfer surface 6 and the largest possible calibrated wick combustion surface is exposed by the flame choke sleeve 8. so that the burn time dial 29 with the shortest burn timeta number must be pushed under the burn time dial hand 31. This also completes this calibration process and any desired burning time setting can be made on the fixed burning time dial 29 with the burning time dial pointer 31, but without exceeding the “STOP” marking on the burning time dial 29. the 8th shows the smallest possible wick burning surface that 9 on the other hand, the largest possible wick combustion surface.

In the 9 a calibration bar 51 on the plastic wick body 2, in which the rod wick 1 is anchored in a rod wick insert fixation 10, is used in the manually operated lamp for the calibration adjustment of the burning time dial 29 to the wick combustion surface. The flame throttling sleeve 8 with the flame throttling sleeve thread 11 is screwed onto the fuel tank thread 12 until the flame throttling sleeve 8 comes to rest on the calibration bar 51 of the plastic wick body 2 and the largest possible wick combustion surface is released from the opening of the flame throttling sleeve 8. This wick combustion surface area has already been calibrated by the manufacturing plant, for example, to six days of service life, so that the burn time dial 29 is shifted in the burn time dial rail 30 until the six-day service life display is just below the burn time dial pointer 31 of the flame throttling sleeve 8 . This completes the calibration process and the flame throttling sleeve 8 can then be returned to any day display of burning duration, but without exceeding the "STOP" mark. By enclosing the rod wick 1 with a plastic wick body 2, the mass of material on the rod wick 1 is kept as low as possible, resulting in faster wick saturation and thus a shorter waiting time for igniting the lamp to be operated manually

on 10 Figure 1 shows the main fuel tank 24 sealed for storage and transport. A screw-on tank cap 52 with a sealing ring 19 is screwed onto the fuel tank thread 12 with the flame throttling sleeve thread 11 and the rod wick 1 is thus pressed against the tank valve spring pressure, so that the rod wick 1 pushed into the wick insertion space 27 closes the fuel inlet valve 28 and the air supply channel 17. In an alternative embodiment of the screw-on tank cap 52, it can be provided with a flame throttling sleeve thread 11 and additionally with a housing screw thread 35, as a result of which greater stability is achieved. However, the surface of the screw-on tank cap 52 should be corrugated in order to compensate for differences in tension between the flame throttling sleeve thread 11 and the housing screw thread 35 . For purchasing the main fuel tank 24 together with the combustion unit, this is screwed with the flame choke sleeve thread 11 into a fuel tank thread 12 in the lamp cover 53 .

1. a) Flammdrosselungshülse 8 so weit in das Flammdrosselungshülsengewinde 11 einschrauben, bis die Flammdrosselungsöffnung mit der Eichungsmarkierung 50 am Docht 56 in gleicher Höhe ist.
2. b) Danach zur Eichung das Brenndauerziffernblatt 29 auf 20 mit Flammdrosselungshülsenzeiger übereinstellen.
3. c) Anschließend die gewünschte Betriebsdauer mit dem Zeiger auf dem Brenndauerziffernblatt 29 einstellen, ohne STOP zu überschreiten.

A plan view of the main fuel tank 24 is shown in FIG 11 . In the middle is the tank wick fuel transfer surface 7 and adjacent the fuel tank thread 12. The laser passage window 48 is also located on the top of the main fuel tank and next to it is the burn time dial 29 movable in the burn time dial smooth rail 30. The "STOP" mark on the burn time dial 29, which appears after completed calibration process by the burn time dial pointer 31 may no longer be exceeded when setting the operating length. On the very outside of the top of the main fuel tank 24 is a lamp description and an instruction manual 32 which includes the following instructions:

1. a) Screw flame choke sleeve 8 into flame choke sleeve thread 11 until flame choke opening is level with calibration mark 50 on wick 56.
2. b) Then set the combustion time dial 29 to 20 with the flame throttling sleeve pointer for calibration.
3. c) Then set the desired operating time with the pointer on the burning time dial 29 without exceeding STOP.

the shows a plan view of the burning time dial 29 movable in the burning time dial rail 30, shown individually. This dial 29 could be stamped and printed from a moisture-resistant cardboard which is provided with a pressed corrugation at its outer edges in order to achieve a resistance to movement of the timer dial 29 in the timer dial rail 30 which prevents unintentional shifting of the calibration-tuned position of the timer dial 29 when setting on the daily operation time display with the flame throttling sleeve 8 and the combustion time dial pointer 31 should prevent.

The illustration 12b Fig. 12 shows a plan view of the lamp ready for operation when the operating length is manually adjusted by hands and put into operation. In the middle is the rod wick 1, which is enclosed by the wick guide tube 9 and forms a unit with the flame throttling sleeve 8. The illustration given illustrates the calibration process in which the termination of the wick guide tube 9 of the flame throttling sleeve 8 is exactly level with the calibration mark 50, which indicates 13 and then slide the factory calibrated wick burn surface of 20 day length and the movable burn time dial 29 with the 20 burn time indicator in the burn time dial rail 30 under the burn time dial hand 31 into the same position. Any length of operating time can then be set from six to 32 days using the flame throttling sleeve 8 and the combustion duration dial pointer 31, but without exceeding the “STOP” mark on the combustion duration dial hand 31. If the calibration procedure were to be carried out using a calibration bar 51, the flame throttling sleeve 8 would be screwed onto the fuel tank thread 12 by hand until the flame throttling sleeve 8 with the combustion duration indicator 31 comes to rest on the calibration bar 51, as in 16 is presented in a comparable manner.

This would expose the manufacturing plant's largest possible wick burn surface with calibrated six days of service life, and then the six day service life indicator dial 29 would have to be slid under the service life dial hand 31, which would also complete this calibration process.

A further simpler design of the main fuel tank 24 is on the 13 until 20 shown. The tank wick fuel transfer surface 7 is no longer on a movable rod wick 1 but is anchored immovably in the main fuel tank 24 . An air supply duct 17 leads through the tank wick fuel transfer surface 7 and, when the lamp is in operation, allows ambient air to flow into the gas pressure equalization space 39 to equalize the pressure for the consumed fuel. A commercially available wick 56 is used to supply fuel to the tank wick fuel transfer surface 7, which is woven as a support element, for example, around a wick support rod 57 for its straight-line retention of shape and/or is enclosed by a wick support tube 58 down to the tank bottom for its straight-line nature, and only at the fuel tank bottom to the areal fuel consumption is divided apart. The wick 56 can also obtain its stable, straight shape by a chemical treatment, so that the laser reflecting floating ring 49 in the main fuel tank 24 can sink to the bottom of the main fuel tank without any problems during fuel consumption. The descent of the laser specular floating ring 49 can also be guided by another guide member such as the main fuel tank inner wall 24, although this would require a larger laser specular floating ring diameter and also a larger laser passage window area. This is to ensure that the laser reflecting floating ring 49 can sink properly to the bottom of the main fuel tank for measuring the current fuel supply. Except that the tank wick fuel transfer surface 7 is elastic and absorbent, the contacting for fuel flow from the tank wick fuel transfer surface 7 to the wick fuel transfer surface 6 must be by compressive action of the flame choke sleeve spring 13 from the wick fuel transfer surface 6 .

At the figure 13 the calibration process is sometimes shown in which the firing of the wick guide tube 9 is level with the calibration mark 50 and the burn time dial 29 is pushed in accordance with the 20 days of operation in the burn time dial rail 30 with the burn time dial pointer 31. The flame throttling sleeve spring 13 presses the movable rod wick 1 in the wick guide tube 9 to slide against the tank wick fuel transfer surface 7 and permanently maintains the contact pressure even when the height of the flame throttling sleeve 8 is adjusted by the operating time settings.

The illustration of 14 shows a lamp to be operated manually with the hands, consisting of a main fuel tank 24 with a firmly anchored tank wick fuel transfer surface 7, which, however, consists of an elastic and also absorbent material, so that this creates the contact connection for the fuel flow to the wick fuel transfer surface 6. A commercially available wick 56 is used to supply fuel to the tank wick fuel transfer surface 7, which is woven, for example, around a wick support rod 57 as a support element to permanently support its rectilinear shape and/or is guided in a wick support tube 58 to the bottom of the tank and is only separated in terms of area at the bottom of the fuel tank for fuel intake . The combustion unit consists of a completely specially screwed-on main fuel tank cover, on which the entire functional unit from rod wick 1 to burn time dial 29 and operating instructions 32 is present. The completely self-made combustion unit consists of an immovable rod wick 1, the is anchored with a rod wick insert fixation 10 in a plastic wick body 2, through which the air supply channel 17 also leads. The flame throttling sleeve 8 with the burn time indicator 31 is also screwed onto this plastic wick body 2 . It is no longer necessary to calibrate the flame throttling sleeve 8 on the burn time dial 29 since this closed system has already been calibrated by the manufacturing plant and no calibration setting changes take place when the combustion unit is screwed onto the main fuel tank 24 . The operating time is not set according to the movable combustion time dial 29 of the main fuel tank 24, but is set with the combustion time dial pointer 31 on the combustion time dial 29 calibrated by the manufacturer and immovably mounted on the screwed-on fuel main tank cover.

In the illustrations of 15 until 20 a main fuel tank 24 is shown with an immovable tank wick fuel transfer surface 7 on which are bolted remote controllable combustion units fitted with various rod wick ignition systems. It will be at 15 a stick wick 1 is used, in which the heating coil 20 and the flame ignition pins 21 are installed in the wick vaporizer head 3. The flame throttling sleeve 8 is set to achieve the smallest surface area of the wick evaporator head 3 . When screwing on the combustion unit, the two fuel flow contact surfaces from the tank wick fuel transfer surface 7 to the wick fuel transfer surface 6 can have slight height differences, which in the design shown may be a tolerance of up to plus/minus 2 millimeters. The flame throttling sleeve spring 13 presses the rod wick 1 against the tank wick fuel transfer surface 7 to an indefinite extent, so that the flame throttling sleeve 8 must first be calibrated. The flame throttling sleeve 8 gives 15 a very small surface of the wick evaporator head 3 free. With further flame throttling by the flame throttling sleeve 8, the flame is extinguished and the lamp is taken out of operation.

On the representation of 16 For the calibration process, the flame throttling sleeve 8 is screwed onto the thread until the calibration bar 51 or else a calibration hollow truncated cone triggers a resistance on the flame throttling sleeve 8 . The flame choke sleeve 8 that has come to a standstill transmits the position with the flame choke sleeve gear 36 to a flame choke measuring sensor 23, which thus records the largest possible wick evaporator head surface 3, which was calibrated by the manufacturing plant to six operating life days, for example, in its light pulse counter and uses it as a reference level for further flame size settings and burn time calculations. If necessary, a laser fuel gauge 47 sends its light beam through a laser window 48 onto the laser mirror floating ring 49 in the main fuel tank 24, which calculates the current fuel supply by reflecting the light beam back to the laser fuel gauge 47 in the control electronics 44.

In the construction of the lamp from 17 until 20 For example, a main fuel tank 24 is used with an immovably anchored tank wick fuel transfer surface 7 where calibration of the flame throttling sleeve 8 to the wick combustion surface must first be made. No electrical components are contained in the rod wick 1, which is partially provided with a coated wick surface 5, which means that production is simpler. The heating coil 20 is mounted on the wick guide tube 9 and transfers the thermal energy during the ignition process through the wall of the wick guide tube 9 to the rod wick 1 by contact. The flame ignition pins 21 are fixed on top of the control unit. The freedom of movement of the calibration beam 51 and the heating coil 20 are sufficiently taken into account for the calibration process. The permissible difference in height of the tank wick fuel transfer surface 7 to the wick fuel transfer surface 6 with the lamp components, fuel main tank 24 and combustion unit screwed together, is allowed in the illustrations shown 17 until 20 do not exceed the tolerance range of maximum plus/minus 2 millimeters. 17 shows a very small wick burning surface at which the flame can be extinguished and the lamp can be taken out of service by further unscrewing the flame throttling sleeve 8 .

The illustration 18 shows the lamp during the calibration process and the lamp being put into operation by ignition on the rod wick 1 with a neutral tank wick fuel transfer surface 7 without any deviation in height position. The calibration bar 51 can move in a gap opening of the wick guide tube 9 . The flame throttling sleeve 8 rests on the calibration bar 51 by being screwed down and thus comes to a standstill. The largest possible free wick combustion surface was thus calibrated by the manufacturing plant to six operating days, for example. This value is taken from the flame throttling measurement sensor 23 and for further flame choke adjustments are used as a baseline for later service life calculations by light pulse counts on flame choke gauge sensor 23 and flame choke sleeve gear 36. The position of the rod wick 1 with the calibration bar 51 and heating coil 20 would allow the tank wick fuel transfer surface 7 to be 2 millimeters higher or lower and enable a new calibration process. The ignition process is controlled by an infrared sensor 55 and the ongoing operation of the lights is constantly monitored. If necessary, a laser fuel filling gauge 47 sends a light beam through a laser transmission window 48, which is designed, for example, as a ring window, to the laser mirror floating ring 49 in the main fuel tank 24 and calculates the current fuel supply from its sunken position and the resulting time delay of the reflected light beam.

In the illustration of 19 the individual lighting components are shown separately from each other. The main fuel tank 24 with the tank wick fuel transfer surface 7 fixedly mounted is sealed with a peel seal film 59 . In the control unit, the rod wick 1 is pushed down by the flame throttling sleeve spring 13 and comes to rest with the calibration bar 51 on the threaded truncated cone surface. The wick combustion surface is countersunk in the flame choke sleeve 8 for protection. The lamp cover 53 with the air supply and water discharge openings 33 and exhaust gas openings 34 is also separated from the control unit. The transponder 60 shown is intended to enable the unsupervised commissioning and operation of the remote-controlled light only at its installation site, in that this small electronic component is cemented inaccessible in a drilled hole in the tombstone, for example when the light is used on graves, and the control electronics 44 of the light only fully functional and forwards control commands when the transponder 60 is within a specified range of the light.

20 shows a top view of the 17 until 19 pictured lamp. In the middle is the rod wick 1, which is surrounded by the flame throttling sleeve 8. Also shown are the two flame ignition pins 21 and the infrared sensor 55, which controls the ignition process and monitors ongoing lamp operation. Photovoltaic panels 46 are located on top of the control unit and on the outside of the control unit and provide electrical power to the power storage batteries 45 .

Shine after claim 1 until 2 , characterized in that in the main fuel tank (24) the rod wick (1) can be moved within a tank valve spring end stop (16) by the pressure effect of the tank valve spring (14) and thus the fuel inflow valve (28) in the wick insertion space (27) and at the same time the air supply channel (17 ) can be opened on two sealing rings (19), and these opened valves can be closed again by a counter-pressure effect greater than that of the tank valve spring (14) on the tank wick fuel transfer surface (7), from the wick fuel transfer surface (6) or from a screw-on tank cap (52). . Shine after claim 1 until 3 , characterized in that a laser reflecting floating ring (49) is arranged in the main fuel tank (24), which reflects back light signals emitted by a laser fuel filling gauge (47) through a laser transmission window (48) into the main fuel tank (24) and from the Time delay calculates the current fuel supply in the main fuel tank (24). Shine after claim 1 until 4 , characterized in that in the main fuel tank (24) with the rod wick (1) an intermediate fuel store (25) is installed, which ensures a constant wick saturation on the rod wick (1) when the main fuel tank (24) is full or almost empty, in which only as much fuel can flow from the main fuel tank (24) into the intermediate fuel store (25) as compensating air can flow through the air supply duct (17) via the intermediate fuel store (25) into the closed main fuel store (24) due to the lowering of the fuel level at the level control valve (26) and thus promoting the most accurate possible compliance with the calibrated daily specifications. Shine after claim 1 until 5 characterized in that in the case of the remote-controllable lamp, when the two lamp components are joined together with a main fuel tank (24) with a stationary tank wick fuel transfer surface (7), the movable rod wick (1) with its wick fuel transfer surface (6) attaches itself to the stationary Tank wick fuel transfer surface (7) has to adapt, and because of possible height inaccuracies of the two fuel contact transfer surfaces with this type of light, a position determination of the calibrated wick combustion surface by a calibration bar (31), a truncated calibration rod wick type-dependent calibration hollow cone or other resistance-triggering element such as a rivet or screw connection through or on the rod wick, must be made in which the flame throttling sleeve (8) comes to rest on the calibration bar (51) by screwing it down and comes to a standstill through the resistance, and this size maximum approved wick combustion surface area is calibrated by the manufacturing company to a specific fuel consumption so that this is taken as a reference base by the flame choke measurement sensor (23) and further flame size adjustments and operational computer calculations can be made by light pulse counting from the flame choke measurement sensor (23) on the flame choke sleeve gear (36). Shine after claim 1 until 5 , characterized in that in the case of the manually adjustable lamp, when the two lamp components are assembled with a main fuel tank (24) with a movable or immovable tank wick fuel transfer surface (7), the movable rod wick (1) with its wick fuel transfer surface (6) moves under the pressure of the flame throttling sleeve spring (13 ) must be adapted to the movable or immovable tank wick fuel transfer surface (7), and in the case of this type of light, an adjustment must be made from the burn time dial (29) to the calibrated wick combustion surface size by screwing the flame throttling sleeve (8) onto the fuel tank thread (12) until the opening of the wick guide tube (9) is at the same height as the calibration mark (50) on the rod wick (1), which, for example, has been calibrated by the manufacturer to 20 days of burn time, and then the burn time dial (29) so far into the burn time number b lat rail (30) until the 20-day display of the burn time dial (29) is located exactly under the burn time dial hand (31), or calibration can also be carried out by screwing down the flame choke sleeve (8) and doing this on a calibration bench (51) on the Rod wick (1) or plastic wick body (2) comes to rest, or the length of the wick guide tube (9) has been determined by the manufacturing plant so that when sliding back on the rod wick (1) and the lower wick guide tube opening rests on the conical surface of the upper wick fuel transfer surface (6 ) releases the largest possible and calibrated wick combustion surface area, so that this largest possible achievable wick combustion surface size has already been calibrated by the manufacturing plant to, for example, six service life days. A further, more forceful screwing down of the flame throttling sleeve (8) than that on the weaker flame throttling sleeve spring (13) on the stronger tank valve spring (14) may no longer be carried out for the calibration process with the movable tank wick fuel transfer surface (7), since the combustion duration dial pointer (31) is no longer the correct number of calibration days. To deactivate the manually adjustable lamp, however, the fuel supply valve (28) and the air supply channel (17) could be closed by the receding rod wick (1) if the flame throttling sleeve (8) is screwed down further on a longer fuel tank thread (12) in the main fuel tank (24). For calibration adjustment, the burn time dial (29) is moved in the burn time dial rail (30) until the calibrated burn time day number, in this case six operating days, is under the burn time dial pointer (31). This completes the calibration process and any number of days can be set on the fixed combustion time dial (29) by turning the flame throttling sleeve (8) with the combustion time dial pointer (31), but without touching the "STOP" mark indication on the burn time dial (29) may be exceeded. Shine after claim 1 until 7 , characterized in that in the main fuel tank (24) the tank wick fuel transfer surface (7) can also be made of an elastic, absorbent material which produces the touching contact for the flow of fuel from the tank wick fuel transfer surface (7) to the wick fuel transfer surface (6) and thereby neither a tank valve spring (14), nor a flame throttling sleeve spring (13) is required for this type of light, as in 14 will be shown. Shine after claim 1 until 8th , characterized in that in the case of a remote-controllable lamp with a wick lifting and wick lowering mechanism, toothed grooves (54) for the rod wick are arranged horizontally and/or vertically on the wick formed as a rod wick (1) or as a plastic wick body (2), onto which the motor drive gears (37) intervene and change the height of the rod wick (1) or plastic wick body (2), if necessary via a threaded guide, and the flame throttling sleeve (8) releases a controlled wick combustion surface by changing the position of the rod wick (1) or the plastic wick body (2), and this change in position of the rod wick (1) or a plastic wick body (2) is also passed on to a rod wick (1) or a plastic wick body (2) in the main fuel tank (24), which thus closes the fuel inflow valve (28) and the air supply channel (17), respectively by releasing the pressure on the tank wick fuel transfer surface he (7) the tank valve spring (14) can lift the rod wick (1) again up to a tank valve spring end stop (16), on which the sealing ring (19) of the screw-on tank cap (52) can also rest when the main fuel tank is closed, and the fuel inlet valve (28) and opens the air supply duct (17) again. Through the use of a plastic wick body (2), in which a rod wick (1) with a smaller, absorbent material mass is anchored in a rod wick insert fixation (10), a high functional stability of the rod wick is also achieved, which advantageously requires a smaller wick saturation quantity and thus shorter wick saturation times the commissioning causes, as well as a smaller flame extinguishing delay is achieved with controlled decommissioning of the light. Similar operational advantages are obtained by covering a slender rod wick with a plastic wick body (2) in the main fuel tank (24), which also requires a smaller amount of wick saturation and results in faster start-up and a shorter shutdown time, as shown in FIG 06 will be shown. Shine after claim 1 until 9 , characterized in that in the case of the remote-controllable lamp, the lamp start-up and the permanent operational monitoring can be controlled and monitored by the control electronics (44) in that, depending on the lamp design, a moisture measuring sensor (22) measures the wick saturation with fuel on the rod wick (1), the heating coil ( 20) after its active heating-up phase, as a thermal resistance, transmits the wick evaporator head temperature to the control electronics (44) and an infrared sensor (55) confirms the presence of a flame. Shine after claim 1 until 10 , characterized in that in the case of the remote-controllable lamp, photovoltaic panels (46) for the power supply of the electricity storage batteries (45) are applied to the top of the control unit and the outside of the control unit, and the control electronics (44) are only put into operation to the full extent and forward control instructions when the unavailable externally stored transponder (60) is in a predetermined range for the control electronics (44) and thus a secure locality is guaranteed in the unattended remote ignition of the lamp. Shine after claim 1 until 11 , characterized in that the flame throttling sleeve (8) is provided with a flame throttling sleeve gear (36) in which engages a motor gear (37) which, in various versions, is driven by a geared motor (38) and the teeth of the flame throttling sleeve gear (36) at their Motion pulses the light beam from the flame choke measurement sensor (23) so that a counter in the control electronics (44) gets data for the control output for flame size control. Shine after claim 1 until 12 , characterized in that the lamp, which is available via control electronics (44), can also be used without remote-controllable function commands with a programmable automatic operating system, which automatically switches on and off again based on time specifications and/or due to daylight or other influences and as a result more economical and optically more effective lighting tasks can be achieved over longer periods of time with the available fuel supply. Shine after claim 1 until 13 , characterized in that when using a conventional wick (56) in the main fuel tank (24) this around a wick support rod (57) woven and/or arranged in a wick support tube (58) in order to maintain its straight shape and thus ensure trouble-free sinking of the laser reflection floating ring (49) arranged around the wick (56) during fuel consumption, or the laser reflection floating ring (49) is on the inner wall of the main fuel tank guided. Shine after claim 1 until 14 , characterized in that in the light cover (53) a fuel tank thread (12) is introduced into which the flame throttling sleeve (8) can be screwed for transport and storage of the light, the light cover (53) having exhaust gas openings (34) and air supply and water drainage openings (33).
