Definitions

  • the invention relates to a light source.
  • Illuminants usually have one or more light-emitting element units which have one or more light-emitting elements surrounded by an encapsulation material, which are arranged on a carrier, for example a substrate, which in turn has one or more contact surfaces.
  • a formation of an electrical contact of the lighting element unit is usually carried out directly by arranging spring pins, applying a conductive adhesive or a conductive paste or attaching a crimp.
  • ACF-bonded printed circuit boards ACF: Anisotropic Conductive Film
  • solderable metallic surface for soldering other contact elements.
  • such contacts are complex to manufacture and usually inflexible, since they are not repeatedly detachable and reconnectable.
  • a lighting device which has a plurality of LED modules.
  • An LED module has in a lower housing contact elements, which are designed as socket elements.
  • Two adjacent LED modules are electrically and mechanically interconnected by a connector and the female members.
  • the connecting element has a plurality of plugs which cooperate with the socket elements of the two adjacent LED modules.
  • Various embodiments provide a lighting means, in which the formation of an electrical contact can be made with a reduced effort and also the electrical contact can be made more flexible.
  • the at least one light-emitting element may comprise at least one light-emitting semiconductor element.
  • the contact element may be electrically connected to the contact surface directly via a cohesive connection.
  • the cohesive connection can be formed for example by bonding, soldering, welding or gluing, whereby a secure and stable connection between the contact element and the contact surface can be formed, which also does not adversely affect the height of a light-emitting element and thus also of the light source.
  • another component arranged between the contact element and the contact surface is optional.
  • the lighting means may also be designed such that a mating contact element electrically contacts two or more contact elements.
  • the mating contact element can thereby span two or more contact elements, thereby also two or more light-emitting element units can be electrically conductively contacted with a mating contact element.
  • the formation of an electrical contact with a plurality of lighting element units of a light source can be done faster and with less effort.
  • the number of necessary counter contact elements can be reduced, whereby the entire lamp can be made more compact.
  • a connection between two adjacent luminous element units of a luminous means is formed compactly and directly by a contact element of a first luminous element unit having a mating contact element, which is electrically contacted with a contact element of a second luminous element unit, is integrally connected via a connection region.
  • the mating contact element can be connected to a power supply, for example by means of a cable. But it is also possible that for connecting two light-emitting element units, a first mating contact element, which is connected to a contact element of a first light-emitting element, with a second mating contact element, which is connected to a contact element of a second light-emitting unit, via suitable conductor elements, such as a cable , are interconnected. Furthermore, the mating contact element can be soldered onto a printed circuit board and thus electrically conductively connected to the printed circuit board and via printed conductors with further Geqentitle instituten. This can be done for example by means of the MID technology (MID: molded interconnect device).
  • connection As used herein, the terms “connected,” “connected,” and “coupled” are used to describe both direct and indirect connection, direct or indirect connection, and direct or indirect coupling.
  • connection As used herein, the terms “connected,” “connected,” and “coupled” are used to describe both direct and indirect connection, direct or indirect connection, and direct or indirect coupling.
  • identical or similar elements are provided with identical reference numerals, as appropriate.
  • Fig. 1 a designed as a light-emitting bulb 1 is shown, which has a light-emitting unit 2 in the form of at least one contact strip and a support member 3, on which one or more contact surfaces and a light-emitting semiconductor element are arranged, wherein the light-emitting semiconductor element via one or more contact surfaces of the support element 3 is contacted.
  • the light-emitting semiconductor element is surrounded by an encapsulation material 4 in order to protect the light-emitting semiconductor element from environmental influences.
  • a printed circuit board 5 is arranged, on which in turn a contact element 6 is arranged, wherein the contact element 6 is here in the form of a female element, in particular a female connector, which has a plurality of openings 7 is formed.
  • the light-emitting semiconductor element is electrically connected to the contact element 6 via the carrier element 3, the one or more contact surfaces and the printed circuit board 5.
  • the light-emitting means 1 further has a mating contact element 8, which is designed here as a plug element in the form of a connector strip and has a plurality of pin contacts 9, which for forming an electrical contact between the contact element 6 and the mating contact element 8 respectively in an opening 7 of the contact element 6 can be introduced.
  • the contact element 6 and the mating contact element 8 are thus electrically contacted with each other via a plug connection.
  • the directional arrow 10 shows the movement of the Counter contact element 8 in the direction of the contact element 6 to form the connector and thus an electrical contact.
  • the mating contact element 8 is connected via a cable 11 to a power supply.
  • Fig. 2 shows a further embodiment of a luminous means 1, wherein the luminous means 1 may comprise two or more luminous element units 2a, 2b.
  • Each luminous element unit 2 a, 2 b has a respective carrier 3 a, 3 b, a light-emitting semiconductor element surrounded by an encapsulation material 4 a, 4 b, and a contact surface on which a contact element 6 a, 6 b designed as a socket element is arranged, wherein the contact element 6 a, 6 b is located directly here is arranged on the contact surface and via a cohesive connection, formed by gluing, bonding, soldering or welding, is electrically connected to the contact surface.
  • a luminous means 1 in the form of a light module, in which the luminous means 1 also comprises two luminous element units 2a, 2b, each luminous element unit 2a, 2b each have a support element 3a, 3b, a light emitting semiconductor element surrounded by an encapsulation material 4a, 4b and have a contact surface.
  • On the contact surfaces each formed as a plug element contact element 6a, 6b is arranged.
  • the mating contact element 8 is designed here as a socket element and is on a circuit board formed carrier plate 12 is arranged.
  • the two contact elements 6a, 6b can be arranged or inserted adjacent to one another on the mating contact element 8, so that here too two luminous element units 2a, 2b can be connected to one another via a mating contact element 8.
  • Fig. 5 shows an embodiment similar to that in FIG. 3 and FIG. 4 shown embodiment, in which case several, in particular three, mating contact elements 8a, 8b, 8c are arranged on the support plate 12 and the luminous element units 2a, 2b each have two contact elements 6a, 6b.
  • the middle between the two light-emitting element units 2 a, 2 b arranged counter contact element 8 b, which is designed as a socket element, has, as in the in Fig.
