Light with a mobile bar wick

description

The invention relates to a luminaire with a light source operated with liquid fuel, the movable rod wick of which terminates at one end in a fuel reservoir and at the other end into a combustion chamber, a main tank being provided for the fuel which is connected to the fuel reservoir and the liquid level of the fuel in the fuel storage is below the liquid level of the fuel in the main tank, and the fuel storage is associated with a level control valve for the fuel flowing into the fuel storage.

AT 513 817 B1 discloses a luminaire serving as a grave light with a light source operated with liquid fuel, the wick of which ends at one end into a fuel reservoir and at the other end into a combustion chamber, a main tank being provided for the fuel which is connected to the fuel reservoir wherein the fuel reservoir is associated with a level control valve for the fuel flowing into the fuel reservoir. The wick is designed as a Stabdocht. In addition, a height-adjustable flame retardation sleeve relative to the wick is provided, which releases an adjustable combustion surface of the fixedly anchored wick.

Further lamps show DE 203 125 A, AT 266 741 B and DE 199 652 A. The invention has for its object to provide a luminaire of the type mentioned, which has an additional functionality that ensures easy to bewerk- stelligende ignition and has a cost-effective design.

The object is achieved according to the invention in that a movable rod wick is provided with a thread and, at certain subregions, with a moisture-insulating coating, the rod wick with its lower, uncoated and absorbent end region of the wick surface extending into the fuel reservoir and on opposite, also uncoated wick end releases the size of the combustion surface by turning the wick thread.

The subclaims represent advantageous embodiments of the invention.

In the present lamp, the controllability of the flame is not achieved by a moving flame restriction sleeve, but the Stabdocht is displaced in a firmly anchored throttle sleeve. On the one hand, compared with the luminaire known from the prior art, a reduction of the required components is accompanied and, on the other hand, the fuel flow in the bar wick, ie the wick body, is isolated in a moisture-insulated manner and the bar wick protrudes, on the one hand, only with its absorptive end part Refueling at the lower side of the wick into the fuel-level fuel level regulator, and at the opposite end is exposed to an atomizing head on the wick surface, also in a suction and evaporative carrier material without moisture isolation.

The absorbent ceramic rod wick, in addition to its wick evaporator head and its fuel receiving section, is completely glazed and has moisture evaporating or moisture absorbing at its ends in a raw ceramic state. Due to the smooth surface of the glazed screw thread, the frictional resistance during the wicking movement for adjusting the wick evaporation surface and thus for regulating the flame size and opening and closing the level control valve is reduced to a minimum. The Flame choke sleeve is stably connected to power supply lines for the heating coil and the ignition pins with the light tube. When the luminous tube is pushed out of the combustion chamber and the tube is pushed into the combustion chamber, the rod wick slides through the funnel shape of the wick ignition and flame-extinguishing hood and out accurately, so that the firing pins are also at the right distance from the wick evaporation surface.

The flow valve to the rod wick is opened with a functional movement and at the same time by screwing up the rod wick Operating time adjustment scale the combustion surface at Stabdocht increased more and more. If the end of the operating time before fuel consumption is desired, the rod wick is screwed back into the Brennstoffzuflussabsperrventil, and at the same time the flame again reduced, so that with the extinguishment of the flame of the wick body is in a dry storage condition.

To ignite the flame on the rod wick, the wick combustion surface is screwed into its maximum flame size into a wick ignition hood, so that the heat of the heating coil can be transferred particularly effectively to the wick surface for evaporating the liquid fuel due to the superimposed metal surface areas. After the ignition process, the wick combustion surface is returned to the desired flame size and operating time.

The manually adjustable luminaire can also be remotely started up and monitored with a replaceable luminaire tube equipped with electromechanical and electronic control components. So that the owner can obtain information about the current fuel supply for accessing the control unit of the luminaire, tank filling height measuring sensors are arranged on the control unit along the guide rail to the tank space optical measuring method, can detect the liquid level in the tank and, for example, transmit the data to the display monitor of his smartphone in the case of a desired remote inquiry by the authorized user.

With the non-burnable and made of a ceramic material, for example, Stabdocht can be produced not only technically sophisticated lights with a high ease of use and unique reliability, the slightly higher initial cost and refilling with liquid fuel primarily for eco-friendly reusability are determined, rather, so that the consumer can also be offered a very inexpensive lamp, which has the same high security features as the comfort lamp, however, for use as a disposable lamp or as a non-adjustable refillable lamp can be produced.

In the example formed as a disposable lamp, the fuel supply through the Stabdocht is accomplished by the fact that the user can be opened by a rotational movement of the Stabdochtes, as in a thumbscrew, the fuel level control valve and closed again. Since the wings of the Stabdochtes moisture-insulated, or are glazed at a ceramic Stabdocht, a clean handling is guaranteed when touched. A safety tear-off strip fixes the screw thread during transport and storage of the lamp against unintentional threaded loosening, guarantees the user the original filling and, during commissioning, indicates the exact position of exactly one wick turn. In the printed operating instructions, the user learns that commissioning of the luminaire is accomplished by turning the dowel all the way to the right over the wings of the dowel and then moistening the rod wick for ignition with liquid fuel after about one minute.

The luminaire offers the possibility of producing, in particular, one-way luminaires of short to very long operating times due to the unbound liquid fuel quantity, which thus do not require a more complex type of construction and which in no way detrimentally affect the operational safety. Longer operating times can be for example, by attaching a Flammendrosselungsaufsteckhülse reach, with the depending on the throttling size set by the smaller flame size different operating hours.

For the use of the lamp as a grave light outside of lanterns can be used to protect against the weather and a ventilated operating cover, such as metal or refractory glass, which would be a particularly effective light emission would benefit. In a further embodiment, the operating cover can also be equipped with a flame-retardant sleeve, which allows an operating time control according to a combustion duration scale.

When using the luminaire for special festivities, there is also the technical possibility of placing on the wick made of absorbent material such as clay decoration figures or signposts with a heat-emitting illuminated sign which further absorb the fuel liquid from the bar wick and thus become decorative and decorative also lead to larger flame formation.

For clean disposal, the cover taken off during commissioning of the luminaire and attached to the luminaire base is returned to transport the luminaire back to protect it from possible environmental contamination. Due to the simple design of the luminaire, the two essential components of the luminaire, namely the luminaire housing made of plastic for one nen and the Stabdocht from a ceramic to another for the raw material recovery can be very easily separated from each other, in which only the Stabdocht full come out of the lamp housing is unscrewed and both parts are supplied separately for disposal.

The invention is explained in more detail below with reference to exemplary embodiments with reference to the accompanying drawing.

The lamp embodied as a grave light comprises a main tank 12 with translucent walls, which partially surrounds a light source operated with liquid fuel, the rod wick 1 at one end in a fuel reservoir 28 and at the other end in a combustion chamber 25 opens. In addition, the main tank 12 comprises a cycle tank 1 1 opening into the fuel storage 28 for the fuel.

The fuel accumulator 28 is assigned a level control valve 8 for the fuel flowing into the fuel accumulator 28, the main tank 12 being closed in a gastight manner, and the fuel accumulator 28 being connected to the combustion chamber 25 via an air supply duct 6. The liquid fuel can flow from the main tank 12 via the cycle tank 1 1 in the fuel reservoir 28 until the liquid level in the fuel reservoir 28, the inflow opening of the leveling gelungsventils 8 completely completes, and thus a backflow of air from the fuel reservoir 28 into the cycle tank. 1 1 and the main tank 12 is prevented via the inflow opening of the level control valve 8. If the fuel level in the fuel accumulator 28 drops below the upper edge of the inflow opening of the level control valve 8 opening into the fuel accumulator 28, air can flow from the fuel accumulator 28 through the inflow opening of the level control valve 8 into the cycle tank 11 and the main tank 12, so that fuel remains flows into the fuel reservoir 28 until the liquid level in the fuel reservoir 28 is at least again at the level of the upper edge of the inlet opening of the level control valve 8.

The main tank 12 is at least largely associated with the presently cylindrical combustion chamber 25, wherein a lamp tube 13, which may have a visible surface 15, is inserted into the combustion chamber 25. The visible surface 15 may, for example, have a visible surface design 36 with symbols. The luminaire tube 13 is at least sectionally spaced apart by latching elements 17 for the formation of a ventilation gap 16 with respect to the inner surface of the main tank 12, wherein the ventilation gap 16 opens into a fresh air supply channel 21.

Guide bulges 26, which slide in guide grooves 28, stabilize the insertion of the light tube 13 into the combustion chamber shaft 25. For a continuous operation of the light, the cycle tank connection valve 18 remains open through the valve opening curvature 19 and the entire tank contents can be opened without interruption. to be used. By removing the luminaire tube 13 from the combustion chamber shaft 25 and again inserting the luminaire tube 13 into the combustion chamber shaft 25, the valve closing camber 20 slides onto the cyclic connection connecting valve 18 and with supporting backpressure of the valve closing pressure edge 31, the fuel flow becomes the cyclone tank 1 1 by closing the cyclic tank connection valve 18 for several cycle operations interrupted. This functional mechanism finds its application only in luminaire tubes 13 without control unit 55, since in luminaire tubes with an electronic control unit 55, the cyclic tank connection valve 18 always remains open and the fuel supply for cycle operations are controlled electromechanically via the level control valve 8.

In order to ensure an adequate supply of combustion air to the flame, the combustion chamber 25 in the region of the combustion chamber bottom is also connected to the fresh air supply duct 21. In addition, the fresh air supply channel 21 also forms a rain outlet leading out of the lamp, via which rainwater penetrating into the interior of the lamp can be discharged in a simple manner. The fresh air supply channel 21 also ensures, via the rear ventilation gap 16, that fuel present in the main tank 12 is not excessively heated.

To get to the wick 1, the light tube 13 can be lifted by means of gripping grooves 45 upwards over an easily surmountable Fixierwölbung 29 to the greater sliding resistance of the fluorescent tube discharge curvature 30 and in the raised position by means of easily surmountable, smaller Fixierwölbung 29th are fixed, after which the combustion chamber 25 is directly accessible from the front.

The luminaire tube 13 can preferably consist of a heat-resistant material, which is transparent, colored in the desired color, but can also be designed as desired on a visible surface 15 with a visible surface design 36. An improvement of the luminosity can be achieved by providing the luminaire tube 13 with a radiation-reflecting coating 14. In order to avoid unintentional separation of the main tank 12 and the light tube 13 during transport, the light tube 13 by a Leuchtröhrenausschubvölbung 30 latching and be inserted through a combustion chamber sealing film 43 on the lamp in the surrounding main tank 12.

In order to be able to set the flame size as accurately as possible according to the desired operating time length, a flame retardation sleeve 3 comprising the wick 1 is provided in the combustion chamber 25, which at the same time is designed to ignite the wick 1 as a wick ignition cap 59 and through the throttling sleeve holder 2 Stable with the tube 13 is connected. By means of a thread 7, the wick 1 can be guided by a rotary motion on the dial 10 in a linear movement in the flame retardation sleeve 3, so that the wick evaporator head 73 protrudes further and further out of the flame retardation sleeve 3. By a latching spring 39, an unintentional adjustment of the set according to the Brenndauerskala 5 and the alignment mark 23 operating time is avoided. A light intensity indicator bar LA and a small and large flame symbol 42 on the burning duration scale 5 indicate the course of the light intensity control.

The factory calibration of the flame size on the Brenndauerskala on the one hand by a first, firm screwing the wick body of Stabdochts 1 to close the level control valve 8 and then placing the Einstellrades 10 with a zero operating time display the Brenndauerskala 5 and simultaneous fixation to the wick body 1 with As a second component, the flame retardation sleeve 3, also known as wick ignition hood 59, must be secured to the wall of the lamp tube 13 with the restrictor sleeve holder 2 at a defined vertical distance from the wick 1 during factory assembly.

Thus, when using the lamp in a manual operating time setting with the standard tube, without electromechanical components and control unit 55, the illumination duration of individual Einzelleuchtintervalle is freely adjustable, the main tank 12 comprises the separated via an intermediate bottom 38 cycle tank 1 1, wherein the cycle tank 1 1 via a closable cycle tank connection valve 18 is connected to the main tank 12, and via the level control valve 8 with the level-regulated fuel storage 28. Since the flame retardation sleeve 3 because of the Specification for Brenndauerskala 5 must always have a defined height distance to Stab- wick 1 and this would not exist when turning the lamp tube 13 for a continuous operation lights or a cycle operation, there is a replaceable light tube 13 for continuous operation and one for cycle operations. It is also possible to use a special luminaire tube 13 for both operating systems, in which a sliding switch with snap-in function is provided on the luminaire tube 13, with which the flame retardation sleeve 3 is brought to the height-adjustable bar wick 1 when the tube is turned over. An unauthorized access to the light tube 13 and a tank replenishment pressure seal 68, which is provided for filling the main tank (12). is not possible prior to the sale of the luminaire, since a combustion chamber sealing foil 43 with operating instructions 44 is affixed to the luminaire and guarantees the purchaser the originality of production.

The lamp can also be operated outside of lanterns with a cover 33 which is placed on the shaft-like combustion chamber 25. When the cover 33 is put on, the sealing ring 46 is pushed by the recessed grip 35 onto the fixing notch 47 so that it closes the rear ventilation gap 16 and thus protects against the penetration of rainwater. As a result, the cooling air is diverted from the rear ventilation gap 16 through cooling air throughflow openings 48 into the tube interior 13 and can escape from there via the exhaust gas slots 34 to the outside. For the transport of the lamp to and from their place of use a disposal bag 37 is provided in a carrying case magazine 24 at the bottom of the lamp, which allows a comfortable and clean carrying the lamp.

During operation of the luminaire with a control unit 55, the cyclone tank connection valve 18 always remains open since individual illumination intervals are controlled via the geared motor 53 and a motor gear 54 cooperating with a ring gear 9 and the level control valve 8.

The wick wick 1 is assigned to the wick ignition hood 59 with an ignition device comprising a heating spiral 60 and a flame ignition pin 61. The wick ignition hood 59 is placed on the flame restriction sleeve 3, so that the heat of the heating coil 60, also reflected radiant heat from the Oberflächenisolierspiegelung 67, on the metal surface of the flame-retardation sleeve 3 can transfer and can bring the liquid fuel of the center located in the middle Stabdochtes 1 to vaporize. The surface insulation mirror 67 radiates the electrical heat radiation generated by a heating coil 60 and also toward the outside, in the opposite direction to the wick 1, so that this heat radiation is effectively supplied to evaporate the liquid fuel in as heat-free a flow as possible. An ignition spark 62 of the flame ignition pins 61 ignites the fuel gas and thus the flame at the Stabdocht. 1 An infrared sensor 66 monitors both the ignition process and the correct functioning of the luminaire during the entire operating time, since it can also control a day / post-rhythm unattended via a brightness sensor 56. With a solar module 57, the control unit 55 located in the light tube 13 is supplied with electric current via a rechargeable battery which is coupled to the solar module 57. The solar module 57 is arranged to cover the focal length scale 5 in order to prevent a view of the set operating time and, together with the at least one accumulator, ensures the power supply of the electrical components.

The electrical supply line to the wick ignition hood 59 takes place on the one hand via the power lines 64, 65 and via the common ground power line 63 for the heating coil 60 and the flame ignition pins 61.

For controlled extinguishment of the flame, the level control valve 8 is closed by screwing the Stab- wick 1 in the fuel storage 28 with the electric geared motor 53 and thus the fuel supply from the cycle tank 1 1 prevented, causing the flame with the exhaustion of the wick saturation is getting smaller and finally goes out. The wear-free Stabdocht 1 suffers no damage and retains its original size and property for further ignition processes on the calibrated firing scale 5.

The control unit 55 is connected to the gear motor 53 and the motor gear 54 and the wick ignition hood 59, which are located on a guide rail 58, connected, so that during a power transmission to the dial 10, a stable storage is given ger.

For the tank filling level indicator, tank filling height measuring sensors 81 are arranged along the guide rail 58 on the control unit 55 vertically of the main tank 12 for the fuel supply, which information about the fuel level and thus about the fuel supply in the case of a remote inquiry is provided by an optical measuring method Enter tank room.

The Stabdocht 1 protrudes into the fuel reservoir 28 in its lower, moisture-absorbing part with an uncoated wick surface 69. The overlying part of the rod hole 1 has a conical shape, which is already coated moisture-insulating and thus brings the level control valve 8 also in a matching conical shape for closing. The adjoining thread 7 for adjustment is also provided with a sliding coating 71 so as to cause on its frictional surface a maximum low frictional resistance. Finally, the moisture-insulating coating goes up over the further wick body, past the calibration fixing pressure points 4, to the wick evaporator head 73, which is again intended to bring the sucked-up liquid fuel to evaporate and flame without moisture insulation. Around the wick evaporator head 73 is the wick ignition cap 59 with the Fleizwendel 60 and the flame ignition pins 61st

In a particularly user-friendly embodiment, in this functional system, both the flame size and combustion duration setting, as well as the filling of the fuel reservoir 28 are made from the front of the luminaire. In this case, the flame size or the burning time and the opening of the level control valve 8 are accomplished simultaneously by a single rotary movement of the thread 7. The Stabdocht 1 moves depending on the direction of rotation upwards or downwards and thus controls not only the fuel supply in the Brennstoffspeicher 28, but also the free size of the surface of the wick evaporator head 73 by means of fixed to the light tube 13 Wick ignition cap 59 and simultaneously Flame restriction sleeve 3. Reference is made to FIG. 7. The designed as a disposable lamp comprises a housing 75 with the main tank 12, in which the partially moisture-insulated Stabdocht 1 with thread 7 and Stabdochtflügel 74 is completely screwed so that the coated wick surface 70 at the level control valve 8 is fixed and no liquid fuel from Main tank 12 can flow into the fuel storage 28. A gas overpressure bladder 32 permits the expansion and contraction of the fuel in the main tank 12 with temperature changes and thus favors the pressure adjustment when opening the level control valve 8. A cover 33 designed as a kind of protective cover protects the bar wick 1 for transport and storage.

According to FIG. 8, the start-up of the one-way light is shown, in which first the cover 33 is removed and plugged onto the bottom of the light for later light disposal. By hand, on the bar wickets 74, a full bar wicket turn to the right whereby the bar wick 1 is unscrewed over the thread 7 and the coated wick surface 70 releases the level control valve 8 to transfer liquid fuel from the main tank 12 into the fuel storage 28 and can be taken up by the uncoated wick surface 69 via capillary tube 72 from the rod wick 1. The exact position of a Stabdochtumdrehung is thereby indicated by a safety tear strip 77, which after a Wicktumdrehung again has its entire length, but is damaged by a demolition point. After a short wait for wick saturation, the wick evaporator head 73 may be ignited, determining the flame size from the coated wick surface 70 to the uncoated wick evaporation head surface 73. If there is still residual fuel in the main tank 12 when the lamp is disposed of, the rod wick 1 is again screwed in through the threaded rod 7 to the left via the rod wicket 74, thus fueling through the coated wick surface 70 closed to the fuel reservoir 28 via the level control valve 8. The cover 33 from the luminaire floor can then be placed on the luminaire again to protect against contamination. For the use of the light on graves outside of grave lanterns of the lamp, a weather-protective operating cover 82 can be screwed. This has the advantage that the fuel supply quantity is not tied to the interior size of a grave lantern and lamps with particularly long operating times can be set up freely on the graves. The combustion chamber floor, which is bevelled to an edge of the housing 75, deflects any rainwater which may penetrate through the fresh air supply and rainwater discharge openings 83 to the outside. The exhaust gases escape through exhaust ports 84 in the service cover 82.

In a further embodiment, the one-way light can be operated with a special operating cover 82 with a built-in flame suppression sleeve 3 according to a combustion duration scale 5. It is unscrewed when commissioning the one-way light as the first wing having Stabdocht 1 to its calibration mark 40 to the combustion chamber floor. The operating cover 82 with Flammendrosse- ment sleeve 3 is screwed with its asymmetric threaded housing 76, which has a fixed rotational resistance, with the Einstellsichtfenster 85 so far on the Gehäuseschraubgewinde 76, a Gehäuseschraubgewinde until the approximately equal ignition opening 41 in the housing screw thread 76 and the Ein - Overlay window 85 Overlie each other and thus clear the way to Stabdocht 1. After ignition of the rod hole 1 with a gas lighter or an extra-long match, by further turning on the operation cover 82, which may also be referred to as a protective cover, the desired operating length on the firing scale 5 in the setting viewing window 85 is indicated by the indication of the light source. set winderandes while at the same time, depending on the operating time setting the ignition opening 41 on the housing screw thread 76 at least partially closed again. The omission of the wet protective cover roof results in a continuously variable luminaire for operation in an already weather-protecting lantern.

According to FIG. 9, the top view of the safety strip 77 with the tear-off point 78 is shown in particular, which is torn off during the start-up of the luminaire by a wicking rotation via the bar wicket 74 and after a full turn of the wick, it again shows its entire length for inspection. The operating instructions 44 inform the consumer about the commissioning of the luminaire. For the luminaire with a service life scale 5, according to FIGS. 11 and 12, an operating manual is necessary which indicates that the bar weft 1 should be screwed out exactly to its marking ring.

The service life scale 5 is arranged on an operating cover 82 next to a setting window 85, and the adjustable operating time is shown in the indication on the edge of the housing 75 in which the operating cover 82 is screwed onto the housing screw thread 76.

According to Fig. 10 further applications of the lamp are shown, which should illustrate additional decoration options. Decorative flame sleeves 79, for example, can be plugged onto the wick evaporator head 73, which can also be provided with a heat-active luminous color in order to illuminate, for example, a slogan 80 under the effect of heat. This makes the one-way light also suitable as a decorative gift item. Also differently sized flame throttling push-on sleeves 22 can be attached to the Stabdocht 1, so that with a smaller flame size, the operating times can be extended as desired. For a weather-proof use of the luminaire, a heat-resistant, ventilated operating cover 82 can be screwed onto the one-way light. In a specific embodiment, this operating cover 82 can also be equipped with a flame-expansion sleeve 3 and a combustion duration scale 5, so that desired operating lengths can also be set according to a combustion duration scale 5 by means of a setting window 85. For the refillable luminaire, a weatherproof cover 33 may also be used for use outside of lanterns. When attaching this operating cover, a sealing ring 46 located in a recessed grip 35 is pushed up into a fixing notch 47, so that the venting gap 16 is closed and the rainwater is prevented from penetrating. Heated cooling air from the rear ventilation gap 16 can then escape through cooling air throughflow openings 48 and the exhaust gas slots 34 of the cover 33. In order to ensure safety via an unattended ignition on site, an electronic chip, a transponder 86, is arranged at the place of installation of the light, which serves in particular as a grave light. The transponder 86 may, for example, also be embedded in a permanently anchored tombstone, so that the Stabdocht 1 can be ignited only in the transmission / reception range of the transponder 86 and the receiver permanently assigned to the luminaire at the intended location. This also leads to a prevention against theft of the lamp, since we gen the locality of the remote control functionality of the lamp no interest may be present, the lamp, in particular in their design as grave light to escape from their site. A control can, for example, time-controlled and / or by means of a remote control, for example, a smartphone or the like. The control unit 55 can correspond to the transponder 86, which is arranged outside the luminaire, with the control unit 55 being inoperative as soon as it is out of the reach of the transponder 86.
