Description

The present invention relates to a rod-shaped lamp, and more particularly to a bottle lamp powered by batteries, preferably having an elongated, diffuse luminous body and which fits through a bottleneck of ordinary wine, water or beer bottles to access the bottles from within illuminate. The bottle lamp preferably includes one or more LEDs that illuminate an elongate diffuse luminaire, power electronics, and ordinary AA batteries or accumulators that provide the power. The bottle lamp is mechanically dimensioned so that it can be plugged into all ordinary wine bottles, beer bottles, water bottles, juice bottles and similar bottles through the bottleneck with an inner diameter of about 17-18 mm and the bottle diffuses lit from the inside, without the respective bottle must be changed or edited.

State of the art:

From the CN 2326563 For example, a flashlight for illuminating a fake is known from the inside of the bottle, with a common incandescent lamp and associated power supply cable inserted and fixed, for example, in one or more superposed severed wine-bottle tufts. The wine bottles are therefore to edit accordingly or to change, which is expensive.

CN 2304003 and CN 2304003 describe bottle-lamp devices in which the ordinary incandescent lamp with the associated mains supply cable is also inserted from above through a bottleneck, thus being special bottles or vases with exceptionally large bottle-neck openings. In addition, a mains power supply is necessary.

US 5178450 describes a similar device of a bottle lamp like CN2304003 However, which is intended for glasses with a correspondingly large, upper opening and which is also powered by a battery.

US 713360 . US 675565 and GB 443402 describe various devices for attaching flashlights to the neck of a bottle, with the incandescent lamp base substantially resting on the bottle, and therefore the bottle is more likely to be illuminated from the outside. The aim is to make it to ordinary bottles or at the bottlenecks a firm and secure fit of the lamp holder.

US 5504663 describes various flashlight devices that are battery operated and that are either held by a suitable cover glass over a vase and thus in a vase, or that are in a drinking glass or in a vase with an appropriate seat. Other devices can be used in specially manufactured glass molds. The disadvantage here is that the bottle lighting fits only in special bottles and only a relatively short lighting time can be achieved when using small batteries in conjunction with a light bulb.

FR 2755 213 describes a bottle lamp for ordinary standard wine bottles, which can be inserted through the neck of the bottle and which illuminates the bottle from the inside out. The bottle lamp basically comprises a cylindrical glass container with an internal light bulb and batteries, the bottle lamp being hermetically sealed along the bottom side which is inserted into the bottle. A disadvantage of the mechanical design is that only smaller batteries can be used as standard AA batteries, if an outer diameter of the bottle lamp should not exceed 17 mm, and that the bottle lamp has only a small relatively punctiform light source. In addition, the luminosity is great at a simple connection of a light bulb to batteries at the beginning and then decreases with falling battery voltage accordingly fast and strong.

Therefore, it is an object of the invention to provide a device for illuminating bottles from the inside of the bottles, in particular a cost-effective and preferably battery-powered, rod-shaped bottle lamp which overcomes the disadvantages of the prior art and which is mechanically blocked by a bottleneck of commercial wine bottles. , Water, beer and other drinks and spirits bottles can be stuck to illuminate them from the inside out.

A further object of the invention is that the rod-shaped bottle lamp, which fits through the bottleneck of the beverage bottles, by at least one battery that can be filled in an interior of the bottle lamp, is powered, for this purpose at least one battery / rechargeable battery preferably the Standards AA can be used.

Another object of the invention is to make the bottle lamp particularly energy efficient, so that it has the longest possible duration and a relatively constant brightness to one end of a battery / rechargeable battery capacity and the / at least one battery / rechargeable battery largely discharged becomes.

In addition, the light emission should be able to take place over a larger, diffuse luminous surface, which is significantly larger than that of a small light bulb or LED of about 1-4 cm ² .

Detailed description of an embodiment

In 1 is an embodiment of a bottle lamp according to the invention 1 with a lower first end 11 and an upper second end 12 wherein it is intended that the cylindrical bottle lamp 1 from the first end 11 axially up to a final part 30 through a bottleneck 101 can be stuck and the final part 30 the second end 12 the bottle lamp 1 thus on the bottleneck 101 comes to rest ( 4 ). The bottle lamp 1 has the shape of an elongate rod, consisting essentially of a rod-shaped cylindrical filament 8th in a likewise rod-shaped, cylindrical battery container sleeve 3 at her first end 31 passes, with the battery container sleeve 3 then in the further rod-shaped, cylindrical course up to a second end 32 extends. From the second end 32 to a third end 33 has the battery container sleeve 3 a larger second diameter, which is the cylindrical, thicker end part 30 the battery container sleeve 3 forms. Through an opening at the third end of the battery container sleeve 3 can have one or more cylindrical batteries 4 be filled. Furthermore, the bottle lamp includes 1 at its second end 12 a cover 6 that serves, the open third end 33 the battery container sleeve 3 to close and also an electrical switching contact between the batteries 4 and the end cover housing 63 to be able to produce. In addition, the bottle lamp contains 1 a lighting element 2 arranged so that a radiated light substantially to the luminous body 8th which in turn sends the light along from a second end 82 to a first end 81 weiterleitet and along this path on its surface, the light preferably radiates diffuse.

The luminous body 8th and the cylindrical battery container sleeve 3 show their first end 31 until her second end 32 essentially a same first diameter, which is preferably 16.5-17.5 mm, whereby this part of the bottle lamp through the bottleneck 101 the bottle 100 can be plugged. At the second end 32 takes the diameter of the battery container sleeve 3 to the second diameter, which then preferably uniform to the third end 33 extends and thus the final part 30 forms. The second diameter is so much larger than the first diameter that the final part 30 not in the bottleneck 101 can fall and in the place of the second end 32 from the bottleneck 101 is held back and rests on it. The final part 30 has the second diameter of preferably 18-22 mm, and more preferably about 20 mm. It is also conceivable that the final part 30 is produced by a cylindrical ring with the second diameter as the outer diameter, which is on the battery container sleeve 3 glued on with its first diameter, screwed on, or pressed on.

The cylindrical battery container sleeve 3 is designed to be preferably at its first end 31 has a thread through which the luminous element 8th with his second end 82 with the battery container sleeve 3 is connected. A clamping or adhesive connection between the lamp 8th and the battery container sleeve 3 or the like is also conceivable.

The cylindrical battery container sleeve 3 points in its interior at the first end 31 a room with a corresponding mechanical and electrically contacting seat for the lighting element 2 on. The light element 2 includes a board 23 with a power supply electronics 24 , where the board 23 on a first page a bulb 20 which has a first end 21 of the luminous element 2 represents, and where the board 23 on a second side a lighting element battery contact 25 which has a second end 22 of the luminous element 2 represents. The light element 2 is in the battery container 3 arranged so that the first end 21 with the emitted light to the filament 8th way and the second end 22 with the lighting element battery contact 25 to the battery 4 is aligned.

Furthermore, the interior of the battery container sleeve 3 designed so that one or more batteries 4 , preferably the standard AA from the third end 33 filled in and can be included in it. This will be the first filled battery 4 with her first end 41 along the battery container sleeve 3 to the luminous element battery contact 25 pushed so that thereby an electrical contact between the battery contact at the first end 41 and the luminous element 2 arises. The second end 42 one or more batteries 4 is at the upper third end 33 the battery container sleeve 3 initially free and without contact, until the end cap 6 on the third end 33 the battery container sleeve 3 is screwed on and with its inner end to which a cover cap contact 64 may be arranged, the battery contact of the second end 42 the battery 4 touched or contacted. Instead of a screw connection between the end cover 6 and the battery container sleeve 3 Other connection options are conceivable, such as clamping or locking connections.

By screwing on the end cover 6 on the battery container sleeve 3 Through conductive materials of these parts, both an electrical contact between the end cover 6 and the battery container sleeve 3 made, as well as an electrical contact between the battery contact at the second end 42 the battery 4 and the end cap 6 made when the end cap 6 is screwed in far enough. By more or less wide screwing the lid thus an electrical on / off switching function is exercised. Preferred is inside the end cover 6 at its second end 62 the end cover contact 64 arranged as an integral part. The end cover housing 63 is preferably made of a conductive material, such as aluminum or a similar material.

2 shows an alternative device for switching on / off the bottle lamp 1 in which, instead of turning the end cap 6 in terms of the final part 30 and corresponding contact, in the end cap 6 an electrical switch element 65 is attached, the outside of the second end 62 of the end cover 6 is operable.

For the sake of clarity, it is again expressed that the one pole of the battery 4 at her first end 41 with the lighting element 2 directly over the light-element battery contact 25 is in contact and the second pole of the battery 4 at the second end 42 preferably over the end cap 6 , possibly via the switching element 65 and continue over the conductive battery container sleeve 3 with the lighting element 2 is in electrical contact.

Preferably, the outside is on the battery container sleeve 3 until her second end 32 an O-ring 7 deferred, the soft seat of the final part 30 the bottle lamp 1 on the bottleneck 101 guaranteed.

Preferably, the luminous body 8th made of a good light-conducting material, such as Plexiglas, so that in the second end 82 of the luminous element 2 partly radiated light in the axial direction to the first end 81 passed on the other hand radiates as evenly radially on the way there by a roughened surface. Different surface shapes and roughness levels are conceivable, which may favor either a uniform or a partially amplified light emission. In this case, for example, along the filament 8th also radial indentations or narrow more or less deep grooves conceivable that cause an increased light emission at these points. By a roughness of the surface of the filament 8th The light is emitted diffusely at these points.

It is also conceivable to supplement the filament 8th at its first end 81 by a cylindrical or hemispherical end piece 9 attached to the diameter of the filament 8th attaches and preferably contains a mirror surface, the second end 82 of the filament 8th is aligned.

The electrical characteristics of the bottle lamp 1 are essentially due to the power electronics 24 determined, preferably in the luminous element 2 is integrated; but it is also conceivable power electronics 24 in another place, such as the end cover 6 or elsewhere. The power electronics 24 stands with both poles of the battery 4 , which may consist of one or more individual cells, in electrical connection, so that thereby a battery or input voltage U_BATT for the power supply electronics 24 given is. The power electronics 24 generates an output voltage U_ LED or an output current, the supply current for the bulb 20 represents. Task of the power supply electronics 24 it is, from a caused by a discharge, variable supply voltage U_BATT the battery 4 a substantially constant supply current for the lighting means 20 provide, is also substantially independent of the light source 20 decreasing voltage corresponding to the output voltage U_LED is. On the one hand, a constant supply current causes too high currents for the light source 20 otherwise with fully charged batteries 4 and a simple series resistor could occur avoided, on the other hand, but this is also the discharge of the batteries 4 limited and ensures a longer lighting time.

Preferably, one or more white LEDs are used as the lighting means, which will be referred to simply as an LED hereinafter. The white LED requires a relatively high minimum supply voltage for the intended supply current, which is around 2.8-3 V and whose current increases or decreases very rapidly from this minimum supply voltage.

In preferably three series-connected battery cells 4 , which together have a battery voltage U_BAT = 4.8 V when fully charged, drops in the power supply electronics at a voltage drop of 3 V at the beginning of the LED 24 a voltage of 1.8V starting and ending when the batteries 4 to a voltage of U_BAT = 3.1 V, a voltage of 0.1 V from. However, the supply current is constant or approximately constant over the entire duration from the beginning to the end, depending on the circuit complexity in the power supply electronics 24 , If, in this example, the battery voltage U_BAT drops below 3 V, the power supply electronics would start at this point 24 also only this voltage can be output as output voltage U_LED, which would cause a smaller supply current through the LED and thus a lower light output. From a battery voltage U_BAT of less than 2.8 V, no current would flow through the LED. This is done by the power electronics 24 also causes the energy capacity of the batteries 4 fully or largely exhausted. This example is also qualitatively applicable to other LEDs with different voltage-current parameters and to other constellations of batteries 4 , The power electronics 24 is always designed so that it delivers a provided and required for a luminous power LED current relatively independent of the battery voltage U_BATT and of the LED voltage dropping across the LED, which represents the output voltage U_LED.

A preferred embodiment of the power supply electronics 24 is in 2 shown, which contains an npn transistor TR, whose base is connected via a series resistor R1 and R2 to the positive pole of the battery voltage U_BATT and thus receives an input current which generates by an amplification factor also flowing through the LED collector current. A zener diode ZD is used for voltage stabilization, in order to initially create from the varying battery voltage U_BATT a relatively constant bias voltage for the generation of a constant base current via R2. In this way, the LED, or the light source 20 supplied with a relatively constant and thus regulated by the transistor TR current, so that, until the battery voltage U_BATT to the minimum supply voltage of the LED or the bulb 20 has dropped, a relatively constant light emission takes place.

In a simplified embodiment, the Zener diode ZD and the resistor R1 can be omitted, in which case the base of the transistor TR via the resistor R2 to the positive pole of the battery 4 to connect.

Another preferred embodiment of the power supply electronics 24 may also include a DC-DC converter, with which a voltage gain can be made, so that at a generated output current, the output voltage U_LED itself also greater than the input voltage of the power electronics 24 which is the battery voltage U_BATT can be. Thus, even from a single battery cell with a battery voltage of U_BAT = 1.5 V, a white LED can be operated which has at least one LED voltage and thus an output voltage U_LED of the power supply electronics 24 needed by about 2.8V.

Likewise, it is also conceivable that several bulbs 20 , in series or in parallel, from the power supply electronics 24 be supplied, which may have a plurality of output voltages U_LED for powering the LEDs.

Alternatively to the operation of the bottle lamp 1 with batteries 4 can the battery 4 also by a uniform, in itself non-conductive rod with two contacts, which are arranged in the same places as the battery contacts, namely at the first end 41 and at the second end 42 , be replaced. The contacts of the rod are each connected to a first end of a two-wire thin cable, which passes through a preferably centrally disposed hole at the second end 62 of the end cover 6 is performed and connected with its second ends to a power supply unit. This will cause a change of batteries 4 unnecessary.

Finally, in 4 a side view of the bottle 100 with the bottle lamp 1 shown by the bottleneck 101 in the bottle 100 is introduced and with its conclusion part 30 on the top of the bottle neck opening 102 rests. Under a commercial bottle, as it is the starting point for the present invention of the bottle lamp 1 is a wine, water, beer, juice, spirits or other beverage bottle understood that has a bottleneck with an inner diameter of about 16.5-18 mm and a height of about 29 cm.

When the bottle light is switched on 1 the lamp lights up 8th and shines partly light especially through the bottle belly 103 out, the other part is also the bottom of the bottle 104 through light passing through the first end 81 the luminous body exits, illuminated.
