Description

  • The present invention relates to a light emitting diode module, comprising a housing having at least a first housing portion having a substantially circular outline, a support plate which is housed within the housing and on which a plurality of light emitting diodes are arranged, a control unit for driving the light emitting diodes within housed in the housing, means for fixed attachment of the light emitting diode module in a lamp, and at least two electrical connection cables which are connected to the control unit and connectable to an electrical supply device. Moreover, the present invention relates to a luminaire with at least one light-emitting diode module.
  • Lamps and light modules based on one or more light emitting diodes (LEDs) have enjoyed steadily growing popularity in recent years. One of the most important reasons for this development is that light-emitting diodes have a low energy consumption in comparison to other lamps known from the prior art and thereby provide effective light outputs that are comparable to and sometimes even exceed the light output of conventional lamps. In addition, light emitting diodes are distinguished by very long lifetimes compared to other light sources.
  • A disadvantage of the known light-emitting diode modules or the luminaires equipped therewith is that it is not possible for an additional luminaire component, such as a glass, a reflector, a luminaire attachment, a decorative element a Heatsink or the like to attach easily to the light-emitting diode module in a simple manner.
  • The object of the present invention is to provide a light-emitting diode module and a luminaire of the type mentioned at the outset, which enable easy and uncomplicated mounting of an additional (non-electric) luminaire component on the light-emitting diode module.
  • The solution to this problem provides a light-emitting diode module of the type mentioned above with the features of the characterizing part of claim 1. With regard to the lamp, this object is achieved by a lamp of the type mentioned above with the features of the characterizing part of claim 6. The subclaims relate to advantageous developments of the invention.
  • An inventive light-emitting diode module is characterized in that the first housing section has an external thread on which a lamp component, in particular a glass, a reflector, a lamp attachment, a decorative element or a heat sink, can be fastened by a screw connection. The proposed solution according to the invention enables a simple and uncomplicated installation of an additional luminaire component on the light-emitting diode module. The screw provided here allows easy and intuitive handling and also provides a secure connection of the additional lighting component with the light emitting diode module available. The possibility of direct wiring by means of the connection cable allows easy connection of the light-emitting diode module to an electrical supply device. In order to operate the light-emitting diode module according to the invention in a luminaire, the luminaire requires no special due to the direct wiring Bulb holder into which the light-emitting diode module must be screwed or plugged. By dispensing with the light-emitting device equipped with at least one such light emitting module light can be made more compact, since the height of the space, which is to be provided for receiving the at least one light emitting diode module can be reduced in an advantageous manner.
  • In a preferred embodiment, it is proposed that the housing is formed in one piece. This allows the housing to be very easily manufactured in a single manufacturing step.
  • In an alternative embodiment, it is also possible that the housing has at least two housing parts, which are in particular non-positively or materially connected to each other. An (at least) two-part design of the housing advantageously makes it possible to manufacture the housing parts, which form different housing sections, from different materials.
  • In a particularly advantageous embodiment, there is the possibility that the housing is at least partially, preferably completely, made of a ceramic material.
  • Preferably, the means for fixed attachment of the light-emitting diode module in a luminaire may comprise at least one receiving opening which is formed in a bottom of the housing and in which a mounting means, in particular a mounting screw can be used in the assembly of the light emitting diode module in a lamp. As a result, a comparatively secure hold of the light-emitting diode module in a luminaire can be obtained.
  • In order to further improve the hold of the light-emitting diode module in a luminaire, a particularly advantageous embodiment provides that the means for fixed attachment of the light-emitting diode module in a luminaire comprise at least two receiving openings which are formed in the bottom of the housing and in which during assembly of the Light emitting diode module in a lamp each a mounting means, in particular a mounting screw, can be used.
  • In order to be able to secure the mounting means particularly effectively, particularly in the case of a one-piece embodiment of the housing made of a ceramic material, it is proposed in a particularly advantageous embodiment that the means for fixed attachment of the light-emitting diode module in a luminaire comprise at least one engagement element, preferably made of plastic is arranged within the housing and into which the at least one, inserted into the corresponding receiving opening mounting means, in particular the at least one mounting screw, can intervene in sections. By at least partially, preferably intersecting, engagement of the at least one mounting means (for example, the mounting screw) in the engagement element a secure hold of the light emitting diode module is effected in a lamp.
  • In a particularly preferred embodiment, the bottom of the housing may be a separate component, which is attached in particular non-positively or cohesively to a part of the housing. The bottom of the housing may in particular be made of a plastic material.
  • Preferably, the housing may comprise at least one cable passage opening through which the electrical connection cables are passed.
  • In order to protect the light-emitting diodes from environmental influences, in an advantageous embodiment it is possible that the light-emitting diode module has an at least partially transparent or frosted housing cover.
  • In particular, the housing may have a second housing section, which adjoins the first housing section in the axial direction and has a smaller diameter than the first housing section, so that a contact surface is formed between the first housing section and the second housing section.
  • A luminaire according to the invention comprises at least one light-emitting diode module according to one of claims 1 to 5 and at least one luminaire component attached to the light-emitting diode module by a screw connection, which can be in particular a glass, a reflector, a luminaire attachment, a decorative element or a heat sink. The screw connection allows simple and intuitive handling and also provides a secure connection of the additional luminaire component with the light emitting diode module of the luminaire.
  • Preferably, the luminaire may comprise a luminaire housing, within which the at least one light-emitting diode module is arranged.
  • In order to bring about a secure hold of the at least one light-emitting diode module, in a particularly advantageous embodiment there is the possibility that the light comprises a retaining clip to which the at least one light-emitting diode module is attached. Preferably, the at least one luminaire component may comprise an internal thread which corresponds to the external thread of the housing for attaching the luminaire component to the light-emitting diode module.
  • There is also the possibility that the lamp comprises at least one threaded ring, which comprises a corresponding with the external thread of the housing internal thread. Thereby, the lamp component can be fixed to the housing of the light emitting diode module using the screw ring in a simple and secure manner.
  • The concept presented here and described in detail above is suitable both for different embodiments of luminaires in the interior, as well as for different embodiments of lights in the outdoor area. For example, pendant luminaires, wall luminaires or recessed ceiling luminaires should be mentioned in this context.
  • According to a further aspect, the present invention relates to a luminaire with at least one light-emitting diode module, comprising
    • at least one light emitting diode module having a housing, a support plate which is housed within the housing and on which a plurality of light emitting diodes are arranged, a control unit for driving the light emitting diodes, which is housed within the housing, and at least two electrical connection cables connected to the control unit and to an electrical supply device can be connected, and
    • a clamping bracket which is attached to the housing of the light-emitting diode module and is formed so that the light-emitting diode module can be clamped in a mounting opening fixable. In this way, a recessed light is created on the basis of at least one direct-wired light-emitting diode module, the simple
    Way in a mounting hole (for example, in a mounting hole of a ceiling element) can be mounted.
  • Preferably, the housing of the light-emitting diode module at least partially, preferably completely, be made of a ceramic material.
  • In order to improve the cooling of the light-emitting diode module during operation of the luminaire, in a particularly preferred embodiment there is the possibility that the housing of the light-emitting diode module has a first housing section which at least partially has along its outer circumference a rib structure with a multiplicity of axially extending (FIG. and spaced) ribs. As a result, an improved guidance of the cooling air is achieved.
  • In a preferred embodiment, it is proposed that the housing is formed in one piece. This allows the housing to be very easily manufactured in a single manufacturing step.
  • In an alternative embodiment, there is the possibility that the housing has at least two housing parts, which are in particular non-positively or cohesively connected to each other. This at least two-part design of the housing makes it possible in an advantageous manner to produce the housing parts, which form different housing sections, made of different materials.
  • In an advantageous embodiment, the housing may have a cable feedthrough opening through which the two electrical connecting cables are led.
  • In a particularly preferred embodiment, it is proposed that the housing comprises a housing bottom which has at least one receiving opening, preferably two receiving openings, into which a mounting means, in particular a mounting screw, can be inserted for mounting the light-emitting diode module on the clamping bracket. By this measure, a secure hold of the clamp on the light emitting diode module can be achieved via screw. In order to be able to secure the mounting means particularly effectively in a one-piece embodiment of the housing made of a ceramic material, it is proposed in a particularly advantageous embodiment that the light-emitting diode module comprises at least one engagement element preferably made of plastic, which is arranged inside the housing and into the housing the at least one mounting means, in particular the at least one mounting screw, inserted into the corresponding receiving opening can engage in sections. By at least partially, preferably intersecting, engagement of the at least one mounting means (for example, the mounting screw) in the engagement element a secure hold of the light emitting diode module is effected on the clamping bracket.
  • Preferably, the housing may have at an end opposite the housing bottom an annular flange which laterally encloses a light exit surface of the light-emitting diode module. This flange is after mounting the LED module in the mounting hole on the outer edge.
  • Preferably, the housing may be at least partially made of a ceramic material.
  • In a particularly preferred embodiment, there is the possibility that the housing bottom is a separate component, the non-positively, in particular by means of clip connection means which are formed on the second housing portion of the housing and the housing bottom, or cohesively, in particular by means of an adhesive bond with the housing connected is. The housing bottom can in particular be made of a plastic material.
  • In a particularly preferred embodiment it can be provided that a lamp cover is attached to the annular flange, which has a transparent or frosted portion through which the light emitted by the light emitting diodes during operation can be transmitted. By appropriate design of the lamp cover targeted visual accents can be set. Preferably, the luminaire cover can be non-positively, positively or materially connected to the annular flange of the housing.
  • In a preferred embodiment, there is the possibility that the clamping bracket has a planar holding section, on which the light-emitting diode module is mounted. Preferably, the planar holding portion may have a first bore and a second bore through which one of the two mounting screws is passed.
  • In a particularly preferred embodiment, it is proposed that the clamping bow is executed bent in sections and has two resilient, opposing clamping portions, which are designed so that they can fix the light emitting diode module during assembly to an inner edge of the mounting opening by clamping. This is an intuitive installation of the light emitting diode module in the mounting opening, which at the same time provides a secure hold of the light-emitting diode module in the mounting opening.
  • Due to the direct wiring of the at least one light-emitting diode module with the electrical supply device, the luminaires according to the invention do not require any light-emitting means. By dispensing with the lamp holder, the lights can be made more compact, since the height of the space, which is to be provided for receiving the at least one light-emitting diode module, can be reduced in an advantageous manner.

  • With reference to Fig. 1a to 3 comprises a light-emitting diode module 1, which according to a first embodiment of the present
  • Is executed invention, a housing 2, which is made of a ceramic material and in the present case partially hollow cylindrical. Inside the housing 2, a receiving space is defined, within which a circular support plate 3 is arranged, on which a plurality of light-emitting diodes 4 (in this embodiment, a total of fifteen light-emitting diodes) are arranged.
  • The light-emitting diode module 1 further has a transparent or frosted housing cover 5 for the light emitted by the light-emitting diodes 4 during operation, which - as in particular in FIG Fig. 2 - is attached to a first end of the housing 2 and in the present case has an outwardly extending curvature. In an alternative embodiment, the housing cover 5 of the housing 2 may also be formed plan. A in the axial direction of the housing cover 5 adjacent first housing portion 20 is formed as a threaded portion having an external thread 20 '. A second hollow-cylindrical housing section 21 adjoining the first housing section 20 with the external thread 20 'in the axial direction is offset inwardly in the radial direction, so that the second housing section 21 of the housing 2 has a smaller outer diameter than the first housing section 20. Due to the diameter jump from the first housing portion 20 to the second housing portion 21, an annular contact surface 24 is formed, which can be brought into contact with the assembly of the light-emitting diode module 1 on a mounting surface. At the second housing portion 21, a third housing portion 22 connects, which is conically shaped in this embodiment. At the end of the third housing section 22, a circular housing bottom 23 is formed. The housing 2 of the light-emitting diode module 1 is preferably made of one piece Ceramic material produced. Alternatively, for example, there is also the possibility that the housing bottom 23 is a separate component, which may be made of a plastic material, for example, and non-positively (for example by means of clip connection means which on the third housing portion 22 of the housing 2 and the housing bottom 23rd are formed) or cohesively, in particular by means of an adhesive connection, may be connected to the housing 2. According to a further alternative embodiment, it is also possible that the housing bottom 23 and the third housing portion 22 are formed as a separate, one-piece component, which is preferably made of a plastic material and non-positively (for example by clip connection means) or materially connected to the second housing portion 21 is. According to yet another alternative embodiment, there is the possibility that the housing bottom 23, the third housing portion 22 and the second housing portion 21 are formed as a separate, one-piece component, which is preferably made of a plastic material and non-positively (for example by clip connection means) or cohesively with the first housing portion 20 is connected.
  • For operation, the light-emitting diode module 1 further comprises a not explicitly recognizable control unit for driving the LEDs 4, which is connected to the LEDs 4 and is also housed within the housing 2. The control unit is presently arranged in a space which is bounded by the support plate 3 and the housing bottom 23. In the housing bottom 23, two receiving openings 25, 26 are formed, in each of which a mounting means, in particular a mounting screw, can be used for the assembly of the light-emitting diode module 1. In this way, the light-emitting diode module 1 can be permanently installed in a luminaire. To the mounting means, in particular in a one-piece design of Housing 2 made of a ceramic material to secure particularly effective, the light-emitting diode module 1 comprise at least one preferably made of plastic and not explicitly shown here engagement element which is disposed within the housing 2 and in which the mounting means used in the receiving openings 25, 26 (in particular Mounting screws) can intervene in sections. By at least partially, preferably intersecting, engagement of the mounting means in the engagement element a secure hold of the light emitting diode module 1 is effected in a lamp.
  • The conically shaped in this embodiment, second portion 21 of the housing 2 has a cable feedthrough opening 27 through which in Fig. 1a to 4 not explicitly shown electrical connection cable 7, 8 (see Fig. 4 and 5 ), which are connected on the one hand to the control unit for driving the LEDs 4 and on the other hand can be connected to an electrical supply device.
  • The outer thread 20 'provided on the first housing section 20 is designed so that a luminaire component, such as, for example, a glass, a reflector, a luminaire attachment (in particular made of plastic), a decorative element or a heat sink, can be fastened thereto. In this case, there is the possibility that the luminaire component, which can be attached to the outside of the first housing section 20 of the housing 2, has an internal thread which corresponds to the external thread 20 'of the housing 2. Alternatively, the luminaire component can also be fastened to the external thread 20 'of the housing 2 by means of a screw ring which has an internal thread.
  • With reference to Fig. 4 and 5 there is shown a luminaire 100 which has two light-emitting diode modules 1 of the type described above. The luminaire 100 comprises a luminaire housing 101, which forms a receiving space 102, and a housing cover 103 with a rectangular outline and a first circular receiving opening 104 and a second circular receiving opening 105, the diameters of which are selected such that the second housing sections 21 of FIGS Light emitting diode modules 1 can be passed through the circular receiving openings 104, 105.

The headband 106 further includes a planar retaining portion 1064 which extends parallel to the bottom 109 of the lamp housing 101 and two pairs of holes 1065, 1066. Through each of the holes 1065, 1066 of the two pairs of holes a fastening screw 112 is passed during assembly and with one of the Receiving openings 25, 26 of the two housing 2 of the light-emitting diode modules 1 screwed. This makes it possible to integrate the two light-emitting diode modules 1 firmly in the lamp 100. The bottom 109 of the lamp housing 101 also has a cable feed-through opening 111, through which the electrical connection cables 7, 8 can be passed for connection to an electrical supply device not explicitly shown here.
  • The luminaire 100 furthermore comprises two luminaire attachments 9a, 9b which are each attached to one of the two light-emitting diode modules 1 by means of a screw ring 10a, 10b. Each of the two screw rings 10a, 10b has an internal thread, which corresponds to the external thread 20 of the housing 2 of the respective light-emitting diode module 1 and thereby enables the connection of the lamp caps 9a, 9b with one of the two light-emitting diode modules 1.
