Cuts through an assembled arrangement of FIG. 7 to FIG. 9.

In Fig. 1, a lighting arrangement according to the invention in the form of a battery-powered candle with different assemblies in a longitudinal direction LR is offset from each other and shown aligned with respect to a central longitudinal axis ML. The arrangement contains, in particular, a sleeve-shaped main body HU, an insert assembly EZ and an extension body FO, which can be joined together in the longitudinal direction.

The sleeve-shaped base HO is advantageously formed substantially pot-shaped with a circular cylindrical surface area MF and a bottom BO and a longitudinal direction LR the bottom BO opposite set opening OH. The sleeve-shaped base body, also referred to as sleeve for short, is essentially rotationally symmetrical about a central longitudinal axis ML. The cross-section of the opening OH is substantially equal to the internal cross-section of the space surrounded by the lateral surface MF interior. In the region of the opening OH special structures, such as projections, depressions, grooves, etc. may be provided to ensure an improved fixation of the extension body FO in the opening OH of the sleeve HU. Not visible within the sleeve and in the illustration of FIG. 1 centering structures may be provided to the insert assembly EZ in defined Angle alignment to keep the center longitudinal axis ML. Such alignment structures may, for example, a projecting radially inwardly from the inner wall projection, for. B. in web form, include. In the bottom BO and / or in the lateral surface MF recesses may be provided for the passage of contacts of a charger, in order to charge a located in the assembled state within the sleeve rechargeable battery without disassembly of the arrangement can. Any recesses in the lateral surface MF are advantageously provided at the end of the sleeve facing the bottom and are advantageously concealed by the holder when the candle is used in ordinary candle holders.

In particular, for a use of the candle in the outer region, a cap KA made of elastic material can be attached as a seal over the recesses in the bottom area and / or a sealing ring DR between the lamp extension body and sleeve are inserted. The cap KA can advantageously be dimensioned so that it is substantially hidden by the holder when the battery-operated candle is inserted in conventional holders for wax candles.

The insert assembly EZ contains in particular an insert body EK, which receives in the closed state sketched in FIG. 1 a non-visible battery, a circuit board PL with an electronic circuit arrangement and a light source LED and a contact arrangement with at least one electrically conductive contact K1. The insert body EK consists of several parts, in the example shown a non-visible middle segment and two related to the central segment and in particular articulated connected side segments S1 and S2. The lateral segments S1, S2 are connected to the middle segment preferably along edges parallel to the longitudinal direction LR via film hinges. The free to the longitudinal segment LR edges of the segments S1, S2 facing away from the middle segment SM in the circumferential direction advantageously leave a gap SP between them in the longitudinal direction over at least part of the longitudinal extent of the insert body EK, which gap as a counter-structure to the aforementioned alignment structures in the interior of the Sleeve HU can serve for the defined angular orientation of the insert body EK or the insert assembly EZ within the sleeve HU.

The insert body EK forms in the sketched closed state, a substantially circular cylindrical further sleeve, hereinafter also referred to as an inner sleeve whose outer diameter corresponds substantially to the inner diameter of the sleeve HU. In the closed position of the insert body outlined, a battery enclosed by the latter is advantageously fixed in its position relative to the insert body EK. A circuit board PL used in a corresponding receptacle of the insert body EK is also held in the closed state relative to the insert body EK in a defined fixed position. The wall of the inner sleeve is not visible to the user when using the candle and therefore may have functionally appropriate structures, especially breakthroughs.

The segments S1, S2 and SM of the insert body EK are displaceable relative to each other from the outlined closed position of the insert body EK in an open position, in which at least the battery can be removed from the insert body to allow replacement of a defective battery.

The insert assembly EZ is in the outlined closed position of the insert body through the opening OH of the sleeve HU inserted into the interior of the sleeve and removable from this, with a low elastic Deformation of the insert body EK or another component of the insert assembly EZ may be given, which causes a concern of the insert assembly EZ on the inner wall of the sleeve with slight elastic strain and thus substantially free of wobble.

The extension body FO has in the sketched advantageous embodiment, a substantially cylindrical portion FZ, which is dimensioned so that it can be inserted into the opening OH of the sleeve HU. Advantageously, the extension body FO is thereby held in the sleeve by clamping or snapping and manually destructively removable again from the sleeve. A covering the upper edge of the sleeve cap FT of the extension body limits the insertion depth into the opening OH of the sleeve HU. An attachable to the extension body FO sealing ring DR is in the assembled state advantageously radially between the extension body and the inner wall of the sleeve HU in the opening area.

A flame body FK is modeled on the shape of a candle flame. At least the flame body FK is transparent. Preferably, the extension body FO is made of a material-homogeneous plastic, wherein the plastic material is transparent and can be colored. The material of the flame body or the extension body may contain embedded light scattering particles of other material.

The light source LED focuses light bundled in the direction of the central longitudinal axis to the flame body FK out. The cylindrical section FZ of the extension body FO advantageously surrounds a part of the circuit board PL, which projects beyond the insert body EK, with the light source LED. The light source LED is arranged in the assembled state of the arrangement in the longitudinal direction LR close to a light entrance surface of the extension body FO. The light entry surface is advantageously provided in the region of the base point of the flame body FK and preferably designed as a lens surface, in particular a bundling lens surface.

Fig. 2 shows the insert assembly EZ with its individual components prior to assembly. In the preferred exemplary embodiment outlined, the insert assembly EZ comprises in particular an insert body EK, two contact bodies K1, K2, a battery BA and a circuit board PL.

The insert body EK advantageously consists of three parts, which are connected along edges parallel to the longitudinal direction LR via film hinges FS and form segments S1, SM and S2, the lateral segments S1, S2 respectively being connected to the middle segment but not directly related to one another. The insert body is preferably produced as a one-piece material-homogeneous plastic injection-molded body.

In the insert body, various structures are formed as receptacles for the battery, for the contact body K1, K2 and for the circuit board PL, which are also clearly apparent in their function on the basis of the inserted into the insert body EK components of FIG.

A battery BA is preferably designed as a circular cylindrical rod-shaped battery, in particular in the usual size Mignon (AA) and has a first large battery pole P2 as the bottom of the cup-shaped metallic housing of the battery body and a second small battery pole P1 in contrast in an insulating end plate to the first Battery pole opposite side of the battery body. The lateral surface of the battery body is typically surrounded by an electrically insulating jacket film.

The electronic circuit is advantageously in the form of a rigid circuit board PL, which various electronic components, in particular a programmable controller, for. B. may contain in the form of a microprocessor. On the board, the light source LED is arranged on a side facing the flame body. The board has two contact surfaces KF1, KF2, via which an electrical connection to the battery poles can be produced.

A contact arrangement comprises a first contact body K1 and a second contact body K2. The contact bodies serve for electrical connection of the two battery poles P1, P2, each with one of the contact surfaces KF1, KF2 of the circuit board. The contact bodies K1, K2 are advantageously designed as sheet metal body, which are made of flat sheet metal parts by multiple bending. In particular, the contact body can be made of sheet metal strips. The contact bodies have in the longitudinal region of the circuit board angled contact lugs whose function is explained in more detail with reference to FIG. 3. The contact bodies are advantageously at the same time as charging contacts for connecting a rechargeable battery, optionally with the interposition of the electronic circuit, with contacts of a charger.

The receptacles for the individual components of the insert assembly in the insert body EK can be realized in detail in various ways. It is advantageous to provide a rigid separation between the receptacle for the board PL and the receptacle for the battery BA. Advantageously, the receptacles for the contact bodies K1, K2 are provided in each one of the two lateral segments S1, S2 and the receptacle for the circuit board PL in the middle segment.

In Fig. 3, the components circuit board, battery and contact body are inserted into the insert body in its open position. The circuit board is placed with an edge facing the battery under a projection RP of a holding element of the middle segment SM of the insert body and inserted with two recesses in the board via centering ZS to a board support of the middle segment SM. The contact bodies K1, K2 are inserted into the corresponding receptacles of the lateral segments S1, S2 and held there. The battery BA is inserted in the middle segment SM, but could also be inserted in one of the lateral segments S1 or S2.

The contact lugs KA1, KA2 of the two contact bodies K1 and K2 lie in the longitudinal direction LR at the level of the contact surfaces KF1, KF2 of the circuit board. When closing the insert body EK by pivoting the lateral segments S1, S2 to the film hinges FS relative to the middle segment SM, the contact lugs KA1, KA2 are pivoted about the hinges as pivot axes and come on the contact surfaces KF1 and KF2 for concern. The contact lugs KA1, KA2 preferably lie under elastic prestressing against the contact surfaces KF1 or KF2 of the circuit board, so that good electrical contact is permanently achieved. When the insert body is closed, furthermore, battery contacts BK1, BK2 of the contact bodies K1 and K2 come into contact with the metallic battery poles P1 and P2, respectively.

Cams NO are offset from the contact surfaces KF1, KF2 in the longitudinal direction towards the end of the insert body EK and are provided on the lateral segments S1, S2 when the insert body is closed by pivoting the lateral segments S1, S2 about the film hinges FS on the circuit board PL come to the plant and keep it in the radial direction in a defined position. A latching hook RV in the longitudinal direction of the board PL and a locking hook RH at the longitudinal opposite end engage in closing the insert body in corresponding recesses of the other side part and lock the insert body in the closed position to the closed insert assembly shown in Fig. 1 EZ, in which the individual components are self-holding fixed relative to each other.

In Fig. 4, the insert assembly is shown again in plan view (A), from the first battery BP1 (B) and from the light source LED forth (C) in the open position of the insert body EK. The reference numerals are the same as in FIGS. 2 and 3.

Fig. 5 shows two sections through a fully assembled arrangement. In addition to the components and components already described, the position of a lateral recess AL2 in the wall surface of the sleeve HU and the position of the contact lugs of the contact lugs KA1, KA2 on the contact surfaces KF1 are from the section with a plan view of the board PL according to FIG. 5 (A) or KF2 visible. In this section and in the section in a plane perpendicular thereto with a viewing direction parallel to the surface of the circuit board PL, the lenticular curvature of the light entry surface LF in the region of the foot of the flame body can be seen, which focuses and concentrates the light emitted by the light source LED in the direction of the flame body into the flame body FK directs. Recognizable from both sections is also the arrangement of a recess AL1 in the bottom BU of the sleeve HU. Through the recesses AL1, AL2, in the axial or radial extension of the battery terminals P1, P2 and / or are electrically connected to these contact bodies K1 and K2, charging contacts of a charger can pass through the sleeve and the battery BA load without dismantling the arrangement. On the recordings of the charger can advantageously an alignment, z. Example, be provided above a side contact inwardly projecting cam, which cooperates for the correct position insertion of the candle in the receptacle of the charger with the lateral recess AL2.

In Fig. 6 is a sectional side view of a portion of a flame body FK of an extension body for a battery-powered candle shown in more detail. On the extension body are provided for mechanically connecting the extension body FO with the sleeve HU of the body to the cylindrical portion FZ of the extension body radially outwardly increased locking points RP, which engage in a groove RN on the inner wall of the sleeve. The locking force caused by the locking can be overcome manually without further effort to remove the extension body FO from the sleeve and remove the insert assembly from the sleeve, in particular to replace a defective battery. In a groove on the cylindrical portion FZ of the extension body, preferably spaced by a small amount of the opening of the sleeve covering plate portion FT of the extension body, a sealing ring DR of elastic material is inserted, which is particularly important in outdoor applications of the candle and which in Cases in which a seal of the interior of the sleeve is not required, can also be omitted.

For the optical system of advantage is a preferably integrally formed with the extension body FT at its light emitting diode LED side facing the light source with a convex convex to the light source lens surface LF, which bundling the light emitted by the light emitting diode LED within the extension body in Direction of the flame body FK causes and a light scattering in the plate FT keeps low. In order to further reduce the occurrence of light in the plate FT, a collar LK protruding in the longitudinal direction in the direction of the light source can be provided around the convex lens surface LF, which further prevents light, which is no longer captured by the lens surface or partially reflected thereby, from entering the cylindrical surface To enter section FZ of the extension body and there to be scattered in the direction of the plate FT. The lens surface LF is advantageously formed on a lens body, which is arranged on a relative to the central longitudinal axis of the plate portion FT with respect to the edge region of lesser thickness, so that the axial wall thickness for a radial passage of light between the lens body and the flame body is low. The smaller thickness of the plate portion in the inner region at an axial distance from the lens surface LF reduces the light scattering of the light guided by the lens surface LF in the direction of the flame body FK transversely to the longitudinal axis into the plate portion FT. As a result, an undesirable effect with a lighting of the plate portion FT can be kept low.

In an advantageous embodiment, light-scattering material in the form of light-scattering particles GP can be added to the material of the extension body FO or at least of the flame body FK, which scatter the light of the light source focused by the lens surface LF into the flame body FK in all lateral directions. The light-diffusing particles GP advantageously consist of a transparent, light or only to a very limited extent absorbing material. The light-scattering particles are advantageously made of a different material than the material of the flame body FK. In a preferred embodiment, the light-scattering particles GP consist of glass spheres. The diameter of the light-scattering particles is preferably between 0.05 mm and 0.5 mm. The volume fraction of the light-scattering particles is advantageously between .........% and .............%.

The optical measures of the bundling light surface LF including the shielding collar LK and the reduced axial wall thickness of the region DW extension body FO in axial, in addition to one claimed by the lens surface LF area around the central longitudinal axis are advantageously also individually and in particular also independent of the assembly-friendly structure described above the luminaire arrangement advantageously feasible.

In a further advantageous embodiment, the electronic circuit can be designed in such a way that the light source LED is operated clocked, d. h. That a light output takes place only with a clock frequency in time-spaced light pulses. Especially with light emitting diodes such a pulsed mode is readily possible and advantageous. The clock frequency of such a clocking of the operation of a light-emitting diode is advantageously above 30 Hz, in particular over 50 Hz, preferably above 80 Hz and is thus distinguishable from the eye of the human observer no longer than pulsed operation of a continuous operation. The clocked operation of a light emitting diode LED as a light source is also independent of the described measures of the optical design of the extension body FO and / or the features of the assembly-friendly structure of the arrangement advantageously feasible. The described optical measures of the design of the extension body FO and the clocking of a light emitting diode as a light source show preferred common realization when using conventional rechargeable batteries (rechargeable batteries) of size AA (Mignon) advantageous operating times of over 350 hours with a single battery charge.

In the circuit board PL2, a first opening L11 and a second opening L12 are provided. On the contact body K11, which in turn is advantageously formed by a bent sheet metal body, a fastening structure B11 is formed in a longitudinal direction at the level of the PL2 board, which cooperates with the opening L11 to mechanically connect the contact body K11 with the board PL2 , Such a connection can be formed in particular by a riveting, but in another embodiment, but only by a catch or Verschnappung. Advantageously, the attachment structure B11 also serves for electrical contacting between the contact body K11 and a contact surface on the circuit board PL2. The contact body K11 is fixed in position in the interaction of the fastening structure B11 with the opening L11 relative to the board PL2 by abutment of the contact body K11 on the side edge of the board PL2 facing this.

The contact body K12 has a mounting structure B12 which cooperates with the opening L12 of the circuit board PL2 in order to connect the contact body K12 mechanically and preferably also electrically at the same time to the circuit board PL2. Again, a connection is preferably provided by a riveting, but such a connection can also be done in other ways.

It is essential that the contact body K12 in the connection via the opening L12 and the mounting structure B12 is pivotable relative to the board PL2 transverse to the central longitudinal axis of the arrangement.

On the contact body K11 facing away from the circuit board in the longitudinal direction of a contact tab BK11 for contacting one of the battery terminals of a battery BA is formed. On the contact body K12, a second contact tab BK12 for contacting the other pole of the battery BA is formed on its side facing in the longitudinal direction of the circuit board PL2 side.

On the contact body K11 is a clip KL1 and on the contact body K12 are in the example sketched brackets KL2 formed which comprise the battery BA in the assembled state over an angular range of more than 180 ° and bear resilient projection on the jacket of the battery. In the circumferential direction, the brackets KL1 and KL2 extend only so far that a mutual electrical insulation of the contact body is ensured.

On the contact body K11 in the longitudinal area in the amount of the circuit board PL2 still a bracket-like ring structure KR is formed, which can serve to make a clamping connection of the insert assembly with the extension body FO, for example, the cylindrical portion FZ of the extension body FO has an inner wall, in which the ring structure KR can be used under radial stress. In such a case, the insert assembly can be handled uniformly together with the extension body FO.

The extension body FO in turn shows a flame body FK for a battery-operated candle as a luminaire arrangement and in the example sketched in FIG. 7 an approximately conically extending towards the flame body plate section FV.

For the assembly of the insert assembly, the contact body K11 is mechanically and electrically connected via the attachment structure B11 in cooperation with the aperture L11 and the contact body K12 is connected via the attachment structure B12 in cooperation with the aperture L12 in the board, the contact body K12 relative remains pivotable to the board. The battery BA is preferably first attached to the contact body K12 by the battery over the brackets KL2 snapped across the longitudinal extent of the contact body or inserted in the longitudinal direction of the contact body KL12 through the brackets KL2.
