Description

The invention relates to a lamp, in particular for general lighting, which is designed and intended for mains sockets, in particular wall sockets. Furthermore, the invention relates to a power plug adapter for a light module, wherein power plug adapter and light module form such a lamp.

Power plug lamps are known in many designs for. B. as night and / or orientation lights. They are usually equipped with an incandescent or glow lamp or a light emitting diode as a light source. Are known both battery-powered and to be connected to the power grid embodiments. The mains-connected variants have a mains plug for connection to a socket. The power plug is usually formed on a night light housing.

For example, refer to the known from DE 78 30 032 U1, DE 44 13 504 A1, DE 203 11 185 U1, DE 102 03 925 A1 night and / or orientation lights.

Furthermore, DE 100 54 212 A1 discloses a night light for power sockets, which has a lighting means with a pre-circuit, which is connected between the mains plug and the lighting means. A pre-circuit is always required when a lamp can not be connected directly to the mains voltage, such as a glow lamp or a light emitting diode.

As light bulbs are known compact fluorescent lamps. The light generation based on these compact fluorescent lamps on the same principle as in conventional fluorescent lamps, ie it is low-pressure discharge lamps.

By an electrical discharge between two poles in an evacuated glass tube UV radiation is generated, which is converted by phosphors on the inside of the glass tube into visible light. To start and operate fluorescent lamps need a ballast. In compact fluorescent lamps, the glass tube is bent, so that overall there is a very compact luminous body. Furthermore, in compact fluorescent lamps, the ballast is usually integrated in the lamp. Compact fluorescent lamps are also known as energy-saving lamps. They usually have the classic screw base E 14 or E 27 and can thus easily be screwed into existing incandescent lamps and operated accordingly. By way of example, reference is made to EP 0 601 893 B1. Compact fluorescent lamps are durable, energy-saving lamps.

A lamp designed and intended for power outlets comprising a power plug module with a power plug and a light module with a compact fluorescent lamp is already known from EP 0892210. There are power plug module and light module structurally connected directly to each other, the connection between the light module and power plug module is a reversible mechanical connection, which simultaneously establishes an electrical connection between the light module and power plug module.

US 1 989 752 discloses a power plug adapter having one side provided with a thread and an electrical contact and the other side provided with a bayonet connection for connecting the adapter to the power source, the bayonet connection simultaneously providing the mechanical and electrical connections forms.

The object of the present invention, starting from the above-cited prior art is to provide a lamp comprising a light module and a power plug module, which is constructed even more compact and at the same time plug and module light module are easier to connect or detachable from each other.

This object is achieved according to the invention by a lamp having the features of patent claim 1 and by a power plug adapter having the features of claim 8. Advantageous embodiments and further developments are specified in the dependent of claim 1 and claim 8 claims.

• dass die Verbindung zwischen Leuchtmodul und Netzsteckermodul eine oder mehrere, insbesondere zwei Bajonettverbindungen, jeweils umfassend einen Bajonettsockel oder Bajonettstift, vorzugsweise aus Metall, und eine Bajonettfassung zur Aufnahme des Bajonettsockels bzw. Bajonettstiftes umfasst und
• dass das Leuchtmodul an seiner dem Netzsteckermodul zugewandten Unterseite eine kreisförmige Erhebung aufweist, die im zusammengesetzten Zustand der Lampe in einer Vertiefung des Netzsteckermoduls aufgenommen ist.

The invention provides according to claim 1, a lamp (or: light) before, in particular a lamp for general lighting, which is designed and intended for power outlets, especially wall sockets, and characterized by the following features:

• that the connection between the light module and the power plug module comprises one or more, in particular two bayonet connections, each comprising a bayonet socket or bayonet pin, preferably of metal, and a bayonet socket for receiving the bayonet socket or bayonet pin and
• that the light module has on its underside facing the power plug module a circular elevation, which is received in the assembled state of the lamp in a recess of the power plug module.

The advantages of the invention include the fact that the already advantageous compact fluorescent lamps are now even better for use directly on sockets can be used. This makes the advantages of compact fluorescent lamps, such as long life, low energy consumption and low temperature development, available for these applications. A special compact fluorescent lamp of this type is formed by the lamp MICRO-LYNX from SLI Lichtsysteme, which is commercially available as a built-in lamp in pre-assembled versions.

The compact fluorescent lamp requires a ballast. This ballast can be arranged both in the light module and in the power plug module.

The power socket can be, for example, a protective contact (Schuko) socket or a Euro socket. The mains plug of the mains plug module is accordingly a protective contact (Schuko) - or a Euro plug. Such socket systems are common, for example, in Germany. However, the lamp or power plug module of the lamp may also be suitably configured for any other socket system, i. Also for in southern Europe, the United Kingdom, the United States, Asia and / or Japan customary electrical power socket systems.

Preferably, the power plug module has a housing to which the power plug is molded.

According to the invention, it is provided that the connection between the light module and the power plug module is a reversible mechanical connection. The light module is thus reversibly mechanically connected to the power plug module or connectable. At the same time, the reversible mechanical connection establishes an electrical connection between the light module and the mains plug module, i. realizes the electrical connection of the compact fluorescent lamp.

As a connection between the light module and power plug module one or more, in particular two, bayonet (or: bayonet), in particular each comprising a bayonet base or bayonet pin, preferably made of metal, and a bayonet socket for receiving the bayonet socket or bayonet pin provided. It is preferred in this case if the connection between the light module and the power plug module takes place exclusively via the bayonet connections.

The light module is thus removable from the power plug module. The advantage of this development is, inter alia, the simple interchangeability of the light module. The power plug module can continue to be used after the end of the life of the light module, it must be attached only a new light module.

In a bayonet connection or a bayonet connection, the connection of the parts via a plug-in rotary movement. For this purpose, the two parts to be joined are initially interlocked, usually in that the bayonet socket or bayonet pin is inserted into an opening of the bayonet mount. Subsequently, the parts are pressed against each other by a rotational movement relative to each other, usually by a widening of the bayonet socket or - pin is pushed over a bearing surface of the bayonet mount during rotation and thereby the bayonet base or pin can not be pulled out of the opening of the bayonet mount , Therefore, a release of the parts requires first again a rotary motion, only then the parts can be separated by pulling the bayonet base or pin out of the opening. The angle of rotation is identical when opening and closing, only the direction of rotation is reversed. The angle of rotation can be relatively small and, for example, between 10 ° and 20 °, in particular 14 ° 30 'and 15 ° 30' lie. The bayonet connection is an easy-to-use, especially easy to produce and detachable connection.

The bayonet base or pins on the light module and the bayonet mountings with the openings on the power plug module are preferably provided in the lamp. But also a reverse education or a mixed form is possible. However, should the bayonet connection also be used to make an electrical connection between the light module and the power plug module, then for safety reasons, the former training the bayonet socket on the light module preferable (further explanations below). It is expedient in this case two bayonet sockets, which correspond to two bayonet mountings.

According to an expedient development, the bayonet connections have a reversible latching. This locking can be done for example by at least one provided in the bayonet mount spring, preferably metal spring. When closing the bayonet connection, namely while performing the rotational movement, a resistance that originates from the spring, must first be overcome before the bayonet connection in the closed state transitions (locked). When releasing the bayonet connection, a resistance, which in turn starts from the spring, must also be overcome first, even during the rotational movement, before the light module can be removed from the power plug module.

The compact fluorescent lamp must be connected to the mains voltage via a ballast. For this purpose, an electrical connection between the light module and power plug module is required. Various variants are conceivable for this. According to a particularly preferred and advantageous embodiment of the lamp, it is provided that the electrical connection between the power plug module and the light module is produced or producible via the bayonet connections, in particular via metallic bayonet sockets or bayonet pins, which each contact one or more metal springs in the bayonet mount when the bayonet connection is closed. The metal springs are in turn connected via the mains plug with the mains voltage or connectable. When closing the bayonet connection thus simultaneously the mechanical and the electrical connection between the power plug module and the light module is made.

It is expedient to provide two electrical connections via two bayonet connections. It is also useful if the bayonet sockets on the power plug module and the bayonet base or pins are provided on the light module, as may be accommodated in this way, the metal springs connected to the mains voltage within the power plug module and thus accidental touching the current carrying parts is largely prevented by persons even with removed light module.

According to an advantageous embodiment of the lamp, different lighting modules can be connected to the mains plug module. The lighting modules may differ, for example, in their color and / or their luminosity and / or their shape.

The advantage of this embodiment is, inter alia, that different types of lighting modules can be used according to the wishes of the user by simple replacement. For this purpose, the user can be offered a corresponding lighting module set. The offer may include, for example, light modules of different colors, for example, in addition to white light modules also red, green or blue shining modules. Remote lighting modules with different luminous intensities can be selected. Also, various designs can be provided, i. Light modules with different shapes, for example with a round, square or oval cross section or with a flat or structured front and / or printed motifs.

Preferably, the lighting module has a housing. In particular, the lighting means is covered by a protective cover, in particular a light-directing and / or light-scattering protective cover.

The lamps according to the invention can be designed for continuous operation due to their long life and energy saving property. However, it is also possible to provide an on-off switch, for example a mechanical, user-operable switch and / or a motion-responsive switch, i. a switch coupled to a motion detector, and / or a twilight switch, i. a switch coupled to a brightness sensor. The switches can be provided on the power plug module and / or on the light module.

The invention according to claim 10 provides a power plug adapter which is specially designed and intended for connection to a lighting module comprising a compact fluorescent lamp. In particular, this is Power plug adapter designed and intended for use in a lamp according to the invention. The power plug adapter according to the invention comprises a power plug and at least one connecting element corresponding to the lighting module.

The advantages of this plug adapter arise from the above.

Preferably, a ballast for the compact fluorescent lamp is also arranged in the light module. The ballast may alternatively be accommodated in the power plug adapter.

According to an expedient development of the power plug adapter are at least one, in particular two, bayonet mountings for receiving one or more, in particular two, provided on the light module bayonet cap, in particular of metal, provided as a connecting element or connecting elements, wherein bayonet mount and bayonet each form a bayonet connection.

According to a further development, at least one spring, in particular a metal spring, is provided in the bayonet mount or the bayonet mountings for reversibly latching the bayonet connection and / or for forming an electrical contact with the lighting module. The springs are electrically connected in the power plug module with pins of the power plug, so that they are connected when plugging the power plug into a power outlet with the mains voltage - possibly after closing a switch. The electrical connection between the light module and the mains voltage and thus between ballast or compact fluorescent lamp and mains voltage is established via the bayonet base latching with the metal springs.

The invention will be explained below with regard to further features and advantages with reference to the description of exemplary embodiments and with reference to the accompanying drawings.

The power plug adapter 11 includes a power plug 13 and an adapter body 16. The power plug. 13 has two pins 14. The power plug 13 in FIG 1a, b, c is a Schuko plug (earthing contact plug), as is common, for example, in Germany. It corresponds to corresponding Schuko mains outlets, i. is suitable and designed for direct plugging into these sockets. The power plug adapter 11 is provided with a housing 15 made of plastic, which encloses both the adapter body 16 and the power plug 13. The connection pins 14 of the power plug 13 protrude out of the housing 15. The outer shape of the remaining power plug 13 is formed by the housing 15. The power plug 13 is integrally formed on the adapter body 16. It could be in power plug 13 and adapter body 16 but also to separate parts that are connected to each other or will act.

The light module 12 comprises a compact fluorescent lamp and a ballast (both not shown), ie compact fluorescent lamp and Ballast are integrated in the light module 12. The light module 12 is provided at its not the power plug adapter 11 facing sides with a protective cover 17 made of plastic. This can be transparent, milky, white or colored or be provided with facets and lets the light emanating from the compact fluorescent lamp, if necessary light-directing or scattering, escape to the outside.

The protective cover 17 and the entire light module and also the adapter body 16 of the power plug adapter 11 have in FIG 1a, b, c a circular cross-sectional shape, wherein the circle radius is substantially identical. It can for example be about 75 mm. Alternatively, any other shapes are possible, for example, an angular or oval cross-section.

2a, b, c, d show different views of the light module 12 of the lamp 10 from FIG. 1a, b, c, FIGS. 2a and 2b in a side view, FIG. 2c in a bottom view and FIG. 2d in a plan view. The protective cover 17 can be seen.

The compact fluorescent lamp (not shown) is housed inside the protective cover 17. The underside 19 including the elevation 18 is covered by a plastic housing part 20.

From the bottom 19 of the light module 12 protrude two metallic bayonet base 21 (also: bayonet pins) out. The bayonet base 21 has a circular cross-section. At its free end, the bayonet base 21 are provided with a widening 22. The function of the bayonet base 21 results from the following description of the power plug module 11 with reference to FIGS. 3a, b, c, d. The bayonet base (base part) may be formed, for example, as a so-called GX53 bayonet base according to the industry standard IEC 7004-142-1 and with a GX53 bayonet mount (bracket) according to the industry standard IEC 7005-142-1 corresponding.

The light module 12 can be a standard module, as already used in other applications. For example, modules which are suitable for installation in furniture and are mounted there on suitably designed sockets may be considered. The advantage of the invention in this case is that these modules can now be connected via the power plug adapter 11 directly to a power outlet and thus can be used as a general lighting or as night and / or orientation light. A separate electrical installation of the sockets is then no longer required for these modules. Rather, the lighting modules 12 can be plugged via the power plug adapter 11 in a simple way in any available socket.

As an actual compact fluorescent lamp, i. as a tube, for example, comes a meandering so-called T2 fluorescent lamp into consideration. This has a high efficiency. When using these lamps, a luminous flux of 220 lumens is achievable, the luminous efficacy is high and is 30 lumens / W. The average life of these lamps is 6,000 hours. Instead of a compact fluorescent lamp, another light source could also be provided in the lighting module, for example a printed circuit board equipped with a plurality of light-emitting diodes. The board could be equipped with white light-emitting diodes or colored light-emitting diodes, in particular red, blue, green light-emitting diodes. Also, lighting modules could be provided with different light outputs.

In FIG. 3c, the design of the mains plug 13 can be clearly seen as a Schuko plug.

FIG. 3d shows the plan view of a top side 23 of the network adapter 11 facing the lighting module 12 in the assembled lamp 10. The top side 23 is also covered by the housing 15. The top 23 has a recess 24 which is intended to receive the projection 18 of the light module 12 during assembly of the lamp 10, i. the dimensions of recess 24 and elevation 18 are matched.

Furthermore, FIG. 3d shows two bayonet mountings 25. These each comprise an opening 26 (also: opening) of the housing 15 on the upper side 23 of the power plug adapter 11. The openings 26 have a narrow region 27 and an insertion region 28 which is widened in relation to the narrow region 27. The bayonet mountings 25 correspond to the bayonet bases 21 of the lighting module 12, in particular the dimensions of bayonet mountings 25 and bayonet sockets 21 are matched to one another.

The connection between the light module 12 and the power plug adapter 11 is produced by first inserting the bayonet base 21 with its widening 22 into the plug-in regions 28 of the bayonet mountings 25. Subsequently, a rotational movement follows such that the widenings 22 of the bayonet base 21 are respectively arranged below the narrow regions 27 of the bayonet mountings 25, that is, within the housing 15 of the power connector module 11.

Within the housing 15, below the openings 26 of the bayonet mountings 25, a metal spring (not shown) is arranged in each case. This is intended to lock the widening 22 of the bayonet base 21 in the above-described rotary motion, i. below the narrow portion 27 of the bayonet mount 25. By this locking a defined connection between light module 12 and power plug adapter 11 is made. The metal spring also serves to make electrical contact with the metallic bayonet base 21 and thus of the lighting module 12.
