Description

Optical signal device

Technical Field

The present invention relates to an optical signaling device having at least one light-emitting unit, which comprises at least one light-emitting element, according to the preamble of claim 1.

Background

LED lamps have been known for many years, for example rotary lamps with a blinking effect and a rotating effect, wherein Light Emitting Diodes (LEDs) are used to generate the light. A rotary lamp having a plurality of LEDs arranged in the circumferential direction is known, for example, from document WO 02/066889a1, wherein the LEDs are arranged on a circuit board and the circuit board itself is arranged annularly with respect to the luminous body. Such a signal lamp with LEDs has the advantage that a rotation effect and a blinking effect can be achieved by electronic manipulation of the individual light emitting diodes without the need for mechanical rotation of a part of the lighting device for the rotation effect. Another advantage of using leds is their long service life and low maintenance requirements.

Usually, an acoustic signal generator, such as a piezoelectric disc or a multi-tone generator or a horn, is also integrated in the device, enabling not only optical signals but also acoustic signals.

Furthermore, so-called signal columns are also used, which have three alternative switching modules, which usually have a red, yellow and green color. Since the signal columns are mostly constructed in a modular manner, it is also possible to add additional switching modules in the color blue or white or the like, or to remove a single switching module again when the operating conditions or the application/use purpose change.

Among these modular optical signaling devices, there are, on the one hand, so-called "pre-configured" devices, in which there are fixed, predetermined, unchangeable structures of the modules that are fixedly connected to one another, for example, structures of red, yellow, green color. In this case, an integrated or common cap (Kalotte) is usually provided for the different stages or lighting units/lighting modules. This common cap can be made of one single element or initially also partly of a plurality of individual caps glued/welded together so that it can be handled as an integrated unit/cap.

More common are switching modules in so-called "non-preconfigured" devices or in signal columns, which can be detachably, temporarily connected to one another without tools. In this case, the individual modules (in particular the light and/or acoustic modules) can be combined with one another as desired and can be exchanged or replaced at a later point in time without tools. In this case, a particularly high flexibility with regard to the application possibilities is achieved by means of a standardized switching module. For example, it is also possible to subsequently supplement a "blue" stage or switching module and/or to replace a faulty or damaged lighting module/switching module by a new intact lighting module/switching module without great effort.

In particular for modularly constructed signal columns, it has been common for many years to use "cycles" of current or energy supply to the individual modules by means of electrical lines. Thus, for example, DE 10041202 a1 describes a signal column with at most five stages/light-emitting modules, wherein in addition to five individual energy supply lines or current lines/wires, a negative or neutral conductor/wire is also present in each module, and "circulates" from stage to stage. This means that, up to now, each switching/lighting module has six wires on the inside of the cap, so that all switching modules of one to five signal columns are of the same type of construction and can be interchanged in any desired manner. The signaling of the respective module, for example of the stage numbered 3, is implemented in the following manner: the closed and energized loop of the line numbered 3 is realized by means of a neutral conductor. Therefore, each switching/lighting module must have six switching points, so that an electrical connection can be "cycled" from one module to an adjacent module.

According to DE 102015120280 a1, "circulation" of the energy supply or signals between the individual switching modules is achieved by the circuit board and the connections or contact springs arranged on the end sides.

At present, in such signaling devices, a base or base module is used as an end piece for closing the cap or for fixing the signaling device in the installed position on the cap that partially transmits light and/or light beams. Up to now, such a base essentially comprises a cable clamp, which for the purpose of energy supply or signal supply has been connected or connected to at least two or the above-mentioned six wires/strands.

The base also has various other components, whereby the cable clamp or individual cable clamps (respectively) are fixed in the base or on a base part or the like and electrical contact protection is achieved. Typically, one or more wires have also been installed (respectively) between the light emitting element or circuit board and one or more cable clamps.

All of these are structurally and also economically costly.

SUMMERY OF THE UTILITY MODEL

In contrast, the object of the present invention is to provide an optical signaling device, in particular for LED lamps which emit (rotating) light and/or light beams or a modularly constructed signaling column of the type mentioned at the outset or the like, which reduces the constructional and/or economic outlay.

This object is achieved on the basis of an optical signaling device of the type mentioned above by the feature "the circuit board comprises the cable attachment device". Advantageous embodiments and further developments of the invention can be achieved by means of the further defined measures.

Accordingly, an optical signaling apparatus according to the present invention is characterized in that the circuit board includes a cable attachment device.

This measure makes it possible to: a "base" in the previous sense is not necessary. More precisely, an end element without various components for fixing cable attachment devices and/or for complicated electrical contact protection etc. can be realized. Accordingly, both the structural and the economic outlay are reduced to a large extent. In this way, a new type of design variant of the signaling device is also possible, in which neither the fastening elements nor the mounting base of the signaling device are visible or barely visible.

According to the invention, the installation space or the installation height for placing these components which are no longer required is also saved. A particularly compact or low-profile end element and thus a particularly compact or low-profile signaling device according to the invention can thus be realized.

Preferably, the end element is designed as a mounting element for mounting the signaling device in the operating position. By means of this dual use of the end element or the mounting element for closing or closing the cap and also for mounting/fixing or positioning in the operating/mounting position, the structural and economic outlay is further reduced.

Advantageously, the circuit board comprises at least one or more conductor lines. Thus, one/more conductor lines may be provided for conducting energy or signals between/from the cable attachment device and the light-emitting elements or electrical components of the circuit board/printed circuit board.

In a preferred variant of the invention, the cable attachment device is configured as a cable clamp for detachably connecting and contacting at least two cables. The cable clamp is designed, for example, as a so-called "plug-in clamp", whereby a tool-free connection of the cables or lines/strands can be realized in an advantageous manner.

In a particular embodiment of the invention, the cable attachment device and/or the cable clamp is in electrical contact with the circuit board and/or the conductor track, in particular soldered. Thus, separate contacting and secure fixing of the cable attachment device or cable clamp at/on the circuit board/printed circuit board is not necessary, which further reduces the expenditure.

Advantageously, the cap has at least one circuit board fastening unit for fastening/fixing the circuit board to/on the cap. This measure makes it possible to: separate fastening of the circuit board or the electronic component is not necessary. Therefore, the cost or the number of components is reduced compared to the prior art, which is economically advantageous.

Preferably, at least one fixing device of the fixing unit is arranged at least on two oppositely arranged sides of the circuit board, respectively. This improves the stability according to the utility model discloses a circuit board is fixed.

In a particular embodiment of the invention, the circuit board fastening unit and/or the fastening device comprise a recess and/or a recess of the cap. Advantageously, the recess and/or recess of the cap is oriented/configured in the direction of the (mounted/positioned) circuit board/printed circuit board. In this way, the circuit board/the printed circuit board can be advantageously inserted or removed during production and/or replacement.

The circuit board/printed circuit board can be firmly fixed or mounted on/with the cap (for example at least by means of locking mechanisms or locking projections/locking tongues, adhesives/glues, (plastic) soldering/welding, rivets, bracing/clamping and/or screws/screw connections, etc.). The fastening of the detachable connection, such as a screw connection or the like, is preferably such that the fastening can be detached without great effort when servicing or replacing the circuit board/printed circuit board.

Preferably, the circuit board/printed circuit board has at least one stop element or at least one stop surface. In this way, the stop or the stop surface can be positioned and fixed in an advantageous manner by the circuit board fixing unit and/or by at least one fixing element of the fixing device.

In a specific embodiment of the invention, the cap and/or the circuit board fastening unit and/or the fastening device comprise: at least one latching projection/latching tongue for latching with a stop or stop surface; at least one (internal) thread or thread section for screwing a fixing element configured as a screw. This advantageously enables locking or screwing.

Advantageously, the cap and/or the end element (respectively) have at least one connecting device for detachably connecting the end element, in particular a bayonet connecting device. In this way, the installation/removal and/or the maintenance or repair of the signaling device and/or the light module or the light unit can be advantageously carried out.

Preferably, the signaling device is configured as a (single-stage) LED lamp. However, the signaling device according to the invention can also be designed as a signaling column having at least three lighting units/lighting stages and/or lighting modules, in particular detachably connected switching modules. It is thus possible to realize: in particular in the case of so-called "pre-configured signal posts", which have three or more lighting units or lighting stages and a single or common circuit board/printed circuit board for these lighting units/lighting stages, which circuit board/printed circuit board comprises a cable attachment device or cable clamp according to the invention. Thus, the signal post can also be realized without a so-called "pedestal" in the conventional sense. As described in detail above, this also reduces the structural and economic outlay, particularly in the case of signal columns, accordingly. Thus, new types of design variants of the signal column are also possible.

In one conceivable embodiment of the invention, the lighting unit is designed as a lighting module for detachable connection to an adjacently arranged lighting unit/lighting module. Thus, according to the invention, a single switching module or a single cap can be produced, wherein the "lowermost" or "first" cap or "lowermost" or "first" switching module or "lowermost" or "first" circuit board with the cable attachment device or cable clamp is directly connected to the electrical connection cable.

The further or "upper" cap/switching module/circuit board can be electrically connected/contacted in a manner known per se to the adjacent or underlying switching module and/or to the adjacent or underlying cap/circuit board, respectively. This makes it possible to: it is sufficient to reduce the number of parts of the manufacturer, that is to say to produce a flexibly adaptable switching module with cable clamps, which can be positioned at any desired point in the signal column, wherein separate, relatively bulky bases or the like can be dispensed with. This also enables: a space-saving or relatively low signal post is produced. The advantages in the course of manufacture, distribution or sale and in the increased flexibility of such a switching module can compensate or offset the higher costs of the (unused) cable clamps of other, in particular "upper" switching modules.

The circuit board is preferably designed as a planar/flat circuit board or printed circuit board, on which light-emitting diodes with different light emission directions are mounted. This measure makes it possible to: a common, in particular unique, circuit board can be used for all light-emitting diodes. Preferably, the circuit board has at least one light-emitting diode on the front side and on the rear side, respectively. By not using a plurality of circuit boards, a particularly structurally and/or economically advantageous LED luminaire (e.g. a rotary lamp or the like) or signaling device can be realized according to the invention. The expenditure required for electrically connecting/wiring the entire circuit board is correspondingly low. Furthermore, the very large manufacturing tolerances of the entire circuit board are also not disturbing, since no coordination/matching with other circuit boards is required.

However, as an alternative to the above-described single or common circuit board, at least one first circuit board and a second circuit board are also arranged substantially parallel to one another, wherein at least one of the two light-emitting diodes is arranged on a first front side of the first circuit board and on a second front side of the second circuit board, respectively, wherein no light-emitting diode is arranged on the first rear side of the first circuit board and on the second rear side of the second circuit board. This "back-to-back" arrangement of the two circuit boards also makes it possible to achieve advantageous rotary lighting, that is to say over the entire circumference or over a 360 ° revolution. On the one hand, the slightly higher complexity compared to a single, common circuit board is kept within certain limits, and on the other hand, the assembly of the two circuit boards is slightly less complex than the two-sided assembly described above.

According to the invention, conventional standard assembly techniques can generally be used both for a planar common circuit board and for the two previously mentioned circuit boards arranged "back to back", which is particularly cost-effective and efficient. With the aid of such conventional mounting processes, it is also possible in an advantageous manner for a planar circuit board/printed circuit board to arrange LED components (SMD: surface mountable components) that can be mounted on a surface on a single/common circuit board or printed circuit board in a particularly simple and space-saving manner. The SMD LED component simplifies a compact embodiment of the (common) circuit board or circuit boards and possibly of the cap and/or signaling device according to the invention.

Preferably, the one or more circuit boards are arranged substantially on a longitudinal center plane of the cap and/or of the signaling device oriented in the direction of the longitudinal axis. According to the utility model discloses a (common/only) circuit board or the corresponding centered or central arrangement of printed circuit board can realize: the light-emitting diodes are distributed uniformly and/or emit light uniformly on the (common) circuit board. This applies in particular to different or circumferentially adjacently arranged (circular) sections of LEDs having two or more different light emission directions, which LEDs may have other light emission directions of other light emission sections.

Advantageously, at least one of the two light-emitting diodes is arranged on both sides of the longitudinal center plane and/or on the front side and the rear side of the (common) circuit board, respectively. In an advantageous manner, therefore, light radiation up to 360 °, that is to say light radiation around all sections of a circle/circumference, can be achieved. By suitable control of the individual LEDs or by means of a control unit according to the invention, a favorable rotation or swivel effect and/or flicker effect can be produced.

In a particular embodiment of the invention, the first and/or the second light-emitting section each comprises at least two section light-emitting diodes arranged along the longitudinal axis, and/or at least one light-emitting Diode row is provided, which is oriented substantially in the direction of the longitudinal axis and comprises at least two rows of diodes (Reihen-Diode). Thus, two or more LEDs may be provided for each section, i.e. each first section and/or each second section and/or each third section, respectively. For example, according to the invention, three or more LEDs are provided in a row or column or in a zigzag arrangement or the like for each section in the longitudinal direction. This enables a greater luminous intensity per segment.

Preferably, a plurality of rows/columns and/or at least four or at least six light emitting segments are provided. In this way, it is advantageously ensured that the radiation is emitted by means of the LEDs or rows/columns and/or distributed over the entire (circular) circumference or 360 ° is ensured. For example, all light emitting segments or circle segments/circle portions have a plurality of LEDs or a plurality of rows/columns, respectively.

In a preferred variant of the invention, a plurality of LEDs are advantageously arranged (respectively) on the front side and on the rear side of a (common/unique) circuit board or printed circuit board. On the front side and/or the rear side of the (common/unique) or the circuit boards, for example, on the one hand light-emitting diodes/LEDs with a first main radiation direction are provided, the first main radiation direction is oriented transversely or substantially perpendicularly/orthogonally to the (respective) circuit board, or in other words, which is oriented transversely or substantially perpendicularly/orthogonally to the longitudinal center plane of the cap and/or the signaling device, and, on the other hand, a light emitting diode/LED with a second main radiation direction is provided, the second main radiation direction is oriented in a direction along or substantially parallel to or at the end side of the (respective) circuit board or its end side, and/or, the second main radiation direction is oriented in a direction along or substantially parallel to or in the longitudinal center plane of the cap and/or of the signaling device.

In a particular embodiment of the invention, at least three differently oriented light emitting diodes/LEDs are arranged on the front side and/or the rear side of the (common/unique) circuit board or circuit boards, respectively. The at least one first LED or the so-called "top LED" therefore advantageously has a first main radiation direction which is oriented transversely or substantially perpendicularly/orthogonally to the circuit board or, in other words, transversely or substantially perpendicularly/orthogonally to the longitudinal center plane of the cap and/or of the signaling device. Furthermore, at least one second LED or a so-called first "side LED" is provided, which advantageously has a second main radiation direction, which is oriented along or substantially parallel to the direction of the circuit board or in the direction of the circuit board, and/or which is oriented along or substantially parallel to the direction of the longitudinal center plane of the cap and/or of the signaling device or in the direction of the longitudinal center plane of the cap and/or of the signaling device. Furthermore, at least one third LED or a so-called second "side LED" is provided here, which advantageously has a third main radiation direction which is oriented (also) in or substantially parallel to the direction of the circuit board or circuit boards and/or in or substantially parallel to the direction of the longitudinal center plane of the cap and/or of the signaling device, but at the same time is also opposite to the second main radiation direction by approximately 180 °. Accordingly, the front side is in the sense of the present invention comprising three zones, and/or the back side is in the sense of the present invention comprising three zones.

Accordingly, in the described variant according to the invention, a total of six or (indeed even) four segments according to the invention can be realized in an advantageous manner. In this case, the front-side and rear-side sections each comprise light-emitting diodes/LEDs or so-called "side LEDs", which are arranged both on the front side and on the rear side, wherein these light-emitting diodes/LEDs or so-called "side LEDs" together/together radiate essentially parallel to or on the (respective) circuit board or its end face and/or along or essentially parallel to or in the direction of the longitudinal center plane of the cap and/or of the signaling device, so that a common section can be formed in the sense of the present invention. In this case, therefore, instead of six individual segments, four segments are implemented in the sense of the present invention, wherein, on two oppositely oriented end sides of the common circuit board, a partial segment on the end side and a partial segment on the rear side form a common segment of the cap and/or of the signaling device (in particular of the LED (rotary) lamp).

However, in an alternative variant of the invention, the partial sections can each be designed as separate/separate sections in the sense of the invention. In this way, a particularly elaborate or detailed construction of the realized/individual sections can be achieved according to the invention.

For example, the separation can advantageously be provided by means of one or more circuit boards, and/or at least one separating element can be provided between two sections and/or between rows/columns of a common/single circuit board or LED (rotary) luminaire. Preferably, at least one separating element is provided in the two light-emitting diodes and/or in the two light-emitting directions, which separating element serves to separate the light-emitting diodes and/or the light-emitting directions and to form individual segments. This may be advantageous for certain gyroscopic or rotational effects. If appropriate, the separating element is designed as a reflector or as a reflector element having at least one reflecting surface. Thus, the optical separation effect between the two sections/rows can be further enhanced/improved. Here, stray light can be effectively prevented or reduced.

In a particular embodiment of the invention, at least one reflector element having at least one reflection surface for deflecting/reflecting light and/or light beams is arranged between at least two light-emitting diodes having different light emission directions and/or between two light-emitting sections/lines. This not only makes it possible to effectively prevent or reduce unwanted stray light, but also, if necessary, to achieve focusing/focusing and thus magnification of the light/light beam of the segments by means of the reflectors or reflector elements according to the invention. Accordingly, according to the invention, a circulating/rotating light beam can be clearly and unambiguously generated.

Preferably, the reflective surface of the reflector element is oriented substantially in the direction of the longitudinal axis. This ensures an improved illumination of the sections. This is very advantageous when turning or rotating the light/light beam from a segment to the next/adjacent segment (viewed in the circumferential direction). This also makes it possible to control each segment in an improved manner or by means of a control unit, which results in an improved effect of the swiveling/rotating lamp.

Preferably, the reflection plane of the deflected/reflected light and/or light beam is oriented substantially orthogonal and/or transverse to the longitudinal axis and/or the longitudinal center plane and/or the one or more circuit boards. Accordingly, the reflected light beam or the reflected light is arranged in a transverse plane, i.e. in a reflection plane oriented transverse to the longitudinal direction or the longitudinal axis. For example, in a vertical arrangement of the longitudinal axes of the LED (rotary) lamp or cap and/or of the signaling device, the reflection plane is arranged substantially horizontally. Thus, the light or light beam of the section is reflected at the reflector element and remains in the area of the (circular) section or in the section defined/embodied according to the invention. The revolving/rotating emission/radiation of the light or light beam from segment to segment in the circumferential direction is therefore further improved.

Preferably, a planar/flat reflecting surface and/or a planar/flat reflector element should be provided. This can be achieved without great constructional (manufacturing) expenditure. Alternatively, however, curved reflective surfaces and/or curved reflector elements can also be provided for this purpose. The latter may advantageously be used for concentrating/collecting the light/light beam.

The reflector or the reflector element is advantageously configured as a plastic component, for example a reflector (double-sided) coated with an advantageously reflective layer, and/or the reflector element is advantageously arranged (in particular clamped, locked, spread and/or fixed) between the common/single circuit board and a cap or the like. This enables particularly cost-effective manufacture, installation, disassembly and/or maintenance, etc.

In general, a specific lighting function, such as a blinking effect or a rotation effect, can be achieved by means of an advantageous manipulation of the LEDs. Therefore, the utility model discloses can realize extensive usage. The utility model discloses for example can be used for motor or course of working etc.

A particularly preferred embodiment enables: the LEDs are operated with the aid of an adjustable frequency in order to achieve a rotating or flickering effect of the generated light or light beam. Preferably, a revolution frequency of the revolving light and/or light beam of between about 1Hz to 7Hz, preferably between about 2Hz to 4Hz, is set. This results in a particularly fluent visual impression to the observer.

Advantageously, the control unit comprises at least one dimmer device for varying the brightness/darkness of the light/light beam. Thus, a particularly advantageous optical impression/effect may be produced. This means that the optical perception of the revolving/rotating light/light beam to the person can be improved by means of dimming.

Thus, for example, at a specific point in time, a first section emits light with a luminous intensity of about 100%, and a second section arranged next to or in front in the direction of rotation/circumferential direction can emit light (only) with a luminous intensity of about 20%, and this second section advantageously obtains/has a (gradually/continuously) increasing luminous intensity by means of the control unit until the second section emits light with a luminous intensity of about 100%. At the same time, the first segment may obtain/have a (gradually/continuously) decreasing luminous intensity. Accordingly, at the aforementioned point in time, a third section, which is likewise arranged adjacent to or behind the first section in the direction of rotation/circumferential direction, can again emit light with a luminous intensity of (only) approximately 20%, but this third section advantageously obtains/has a (gradually/continuously) reduced luminous intensity by means of the control unit, i.e. until the luminous intensity of the third section falls to 0% or the third section or its LEDs are switched off.

For example, the dimmer device is configured for superimposing and/or fading in/out light/light beams of at least one light segment/row or of at least two adjacently arranged light segments/rows. This enables an advantageous swivel/rotation of the light/light beam, wherein a "soft" transition between two adjacent light sections/rows can be achieved.

In a specific embodiment of the invention, the dimmer device is designed as a pulse width modulation unit (PWM). For example, in the case of advantageously short on-times and off-times, the human eye perceives only the average luminous intensity of the LED, so that this average luminous intensity can be controlled by means of a switching of the emission time and the extinction time of the LED or a so-called "duty cycle". In this case, the clock frequency should advantageously be set sufficiently high (for example 10kHz) so that the human eye does not perceive an unfavorable brightness fluctuation or a so-called flicker.

Detailed Description

The LED luminaire 1 according to the invention is shown in different schematic views in the figures, which can also be constructed in different variants with luminous images such as continuous light and/or intermittent light and/or flashing light and/or revolving light and/or pulsating light (flakerlight), so-called EVS (enhanced vision system). The LED lamp basically comprises: a cap 2 for at least partially transmitting visible light, and an end element or adapter 3 according to the invention, the end element or adapter 3 being intended to be fixed/mounted in a service position or on a machine, wall, ceiling, floor, vehicle or the like.

In the cap 2, the circuit board 5 or the printed circuit board 5 is fastened to two mutually opposite sides by means of two fastening elements, each of which comprises a recess 4. The circuit board 5 or the printed circuit board 5 is arranged along the cap 2 or on a longitudinal center plane of the cap 2. As is shown in fig. 3, the circuit board 5 or the printed circuit board 5 can be inserted into the cap 2 along the groove 4 and can be fixed or screwed firmly to the stop element 10 by means of two screws 6. For this purpose, the fastening elements each comprise not only a recess 4 but also an internal thread (see fig. 2).

Advantageously, the circuit board 5 or the printed circuit board 5 has a fastening element in its longitudinal direction or (only) on one side along a longitudinal center plane. This means that the circuit board 5 or the printed circuit 5 has one or more fastening elements, namely the recess 4, the screw 6, the stop 10, on one fastening end and no fastening element for fastening the circuit board 5 or the printed circuit board 5 to the cap 2/to the cap 2 is provided on the opposite free end.

A plurality of LEDs 7 and various electronic/electrical components are mounted on the circuit board 5 or the printed circuit board 5 on the rear side and the front side, respectively.

Furthermore, a cable clamp 8 is firmly fixed or soldered to the circuit board 5 or the printed circuit board 5. The cable clamp 8 is designed for two individual wires/strands 9, and is designed in particular as a so-called "plug-in clamp". The wires/litz wires 9 can thus be mounted/contacted in an advantageous manner without tools.

Not shown in detail, various conductor tracks are also present on the circuit board 5 or the printed circuit board 5, as a result of which the cable clamp 8 is electrically connected to the LED 7 and to further components.

The adapter 3 advantageously has a centrally arranged hole 11 for the cable to pass through, and furthermore has two holes 12 for fixing in the operating position. The adapter 3 with the advantageous sealing element 13 can thus be fixed in the operating position by means of screws, not shown in detail, and the cable 16, including the wires/strands 9, can be passed through the opening 11 to the circuit board 5 or the printed circuit board 5 or the cable clamp 8. The wires/strands 9 are thus subsequently fixed/contacted in the cable clamp 8. The cap 2 is then advantageously connected to the adapter 3 by means of the bayonet connections 14, 15.

In the variant shown in the present invention, the "base" in the conventional sense is no longer visible to some extent. Alternatively, other adapters 3 not shown in detail can also be used, for example angularly shaped or triangular in cross-section wall adapters for fixing to vertical walls, tubular adapters and the like.

The low structural and economic outlay of the adapter 3 according to the invention results in completely new design possibilities.
