Technical area

The present invention relates to a luminaire having at least one LED retrofit lamp, wherein the at least one LED retrofit lamp comprises at least one LED, is elongated and has a first and a second end, wherein two terminals are provided for a power supply at the first end and on second end two terminals which are electrically connected together. It also relates to a kit for such a lamp.

State of the art

Some time ago, so-called LED retrofit lamps came on the market, which are designed to replace fluorescent lamps. In addition to some others, applicant's LED retrofit lamps are known as OSRAM SubstiTUBE. In this case, for example, a T8 lamp can be operated in a luminaire with a G13 socket.

Furthermore, it is known, for example from the US 2007/0 223 225 A1 or the US Pat. No. 6,936,968 B2 a lighting device in which a LED retrofit lamp can be mounted in a conventional socket for fluorescent lamps.

The document DE 10 2009 034 536 A1 shows an LED light, which is attachable by means of special fasteners on a mounting wall. Again, the use of either a LED retrofit lamp or a fluorescent lamp is possible.

In the US 2007/0242 466 A1 Also shown is a device to use a LED retrofit lamp in a conventional version for a fluorescent lamp can. Special fittings are required on both sides between the LED retrofit lamp and the fluorescent lamp socket.

The utility model DE 202 16 726 U1 finally discloses a lamp with at least two light sources of different light color. A controller for adjusting the color of the emitted light is present.

Presentation of the invention

The present invention has for its object to expand the application of LED retrofit lamps.

This object is achieved by a luminaire with the features of claim 1 and by a kit with the features of claim 14.

The present invention is based on the finding that the possible uses of LED retrofit lamps can be significantly expanded if possibilities are provided for extending a LED retrofit lamp to a luminaire. This is particularly possible in a simple manner, since the LED retrofit lamp is supplied with electrical power only via the two terminals at the first end, while the two terminals at the second end, unlike a fluorescent lamp, electrically connected to each other, in particular short-circuited , On this basis, a first end cap is provided for terminating the second end of the at least one LED retrofit lamp and a second end cap for terminating the first end of the at least one LED retrofit lamp. In particular, the first end cap serves the aesthetics by concealing the two connections of the LED retrofit lamp. In contrast, the second end cap includes first and second terminals for coupling to a voltage source, the first terminal being coupled to the first terminal of the first end and the second terminal being coupled to the second terminal of the first end of the LED retrofit lamp. The first and second end caps are only connected to each other via the LED retrofit lamp. It may be provided to provide this as a luminaire or as a kit for such a luminaire.

In this way, the customer can decide after purchase whether he wants to use the product as a retrofit lamp or as a separate lamp. This is made possible in particular by the fact that all LEDs of the LED retrofit lamp are only supplied with electrical power via the first end of the LED retrofit lamp. Since the wiring of the LEDs is done internally, the second end of the retrofit lamp need not be coupled to a power supply. This procedure is not possible with the known fluorescent tubes. As a result, the second end of the LED retrofit lamp does not need to be wired. It suffices an electrically passive end cap to complete this second end. Moreover, in the procedure according to the invention, the field of application can be extended since, in the absence of electrical discharges, the electrical disturbances are minimized compared to a fluorescent tube.

Furthermore, the invention is characterized in that in one of the end caps, preferably in the first end cap, a control unit for controlling the brightness of the at least one LED retrofit lamp is arranged. In this case, the control unit may in particular an on / off switch and / or a motion detector and / or a brightness sensor and / or a remote control and / or a control LED and / or a fuse, in particular an internal screw fuse, include. As a result, a multiplicity of functions, in particular comfort functions, can be realized for such a luminaire. A limitation of the functional range compared to fixed luminaires is almost nonexistent.

The at least one LED retrofit lamp preferably comprises a transparent region which covers the at least one LED, wherein the transparent region is made of plastic. The advantage of this solution is that the LED retrofit lamp is almost unbreakable, unlike a fluorescent tube made of glass. As a result, luminaires according to the invention can also be used in areas that are closed to conventional fluorescent lamps because of the danger of destruction, for example gyms, workshops, food trade and the like.

In a particularly preferred embodiment, the second end cap comprises a base. The stand can then include, for example, an additional power supply and a connection to a power outlet. In this way, a lamp according to the invention can be modified with the least effort to a floor lamp.

It is further preferred if the first and / or the second end cap comprises / include a suspension device for wall and / or ceiling mounting. This allows the formation of a lamp according to the invention as a wall or ceiling lamp, in particular pendant lamp.

Further preferably, the first and / or second end cap comprise a Wandmontagefuß, preferably with a joint. In combination with guying cords or wires, therefore, the angle that the lamp takes to the wall can be easily varied. This allows the lighting of a desired area to be optimized.

The at least one LED retrofit lamp may have a first end cap on the first end and a second end cap on the second end from which the respective terminals protrude, the first end cap being configured to snap over the second end cap and / or the second end cap is formed to snap over the first end cap. By a snap closure, a reliable installation of the respective end cap at the respective end of the LED retrofit lamp is made possible in the simplest way. The respective end cap is merely pushed over the respective end cap until, in the intended position, a spring-loaded snap mechanism fixes the end cap on the side of the end cap facing the central part of the retrofit lamp. The respective end cap is so far pushed over the respective end cap until it engages.

Alternatively or additionally, the first and / or the second end cap can be designed to be fastened by means of a Schraubklemmung to the at least one LED retrofit lamp. In this connection, it is particularly preferred if the at least one LED retrofit lamp has a first end cap at the first end and a second end cap at the second end, from which the respective connections project, and a central part, wherein the first end cap via at least one through-hole a screw is attached to the central part and / or the second end cap is fastened via at least one through hole by means of a screw on the middle part, wherein the first and / or the second end cap has / have at least one through hole with the at least one through hole of the respective end cap for Attachment of the respective end cap can be brought over each other / is. In this approach, the mechanism that serves to secure the respective end cap to the center portion may also serve to secure the respective end cap. The additional cost of materials for attaching the respective end caps can therefore be minimal.

The at least one LED retrofit lamp is preferably designed to replace a fluorescent lamp, in particular a T8 fluorescent lamp.

Preferably, a strain relief is further provided in the first and / or the second end cap. Furthermore, a switch for reversibly coupling the first and the second terminal to a voltage source may be provided in the second end cap. This can be realized in a particularly simple manner switching on and off of a lamp according to the invention.

A preferred development is characterized in that it comprises at least a first and a second LED retrofit lamp and at least one coupling device for coupling the at least first and second LED retrofit lamp. In this way, the stability and the achievable brightness can be improved.

In this case, the coupling device can be designed to couple at least the first and the second LED retrofit lamp purely mechanically. Particularly preferably, the coupling device is resilient, in particular as a metal or plastic clip, formed, so that the coupling device can be placed transversely to the longitudinal axis of the first and the second LED retrofit lamp on the first and the second LED retrofit lamp.

Alternatively, the coupling device can also be designed to mechanically and electrically couple at least the first and the second LED retrofit lamp. It can be provided that the coupling device comprises the second end cap for the first LED retrofit lamp and the second end cap for the second LED retrofit lamp. In this way, certain elements for power supply, such as a power supply or a cable with power plug, need only be provided once. In this context, it is particularly preferred if the coupling device itself comprises at least one light source, in particular at least one LED. This can be realized so that almost no transition between the coupling device and the two LED retrofit lamps is recognizable. However, this at least one LED of the coupling device can also be operated independently of the LED retrofit lamps and in this way special functions, such as emergency lighting, orientation or Dekobeleuchtung perceive.

Particularly preferably, the coupling device is at least partially made of a transparent or milky material. In this material, light of the at least one LED of the coupling device is coupled. The supply takes place via the already provided within the coupling device power supply.

Further preferred embodiments emerge from the subclaims.

The described in connection with a lamp according to the invention preferred embodiments and their advantages apply accordingly, as applicable, for a kit according to the invention.
