Definitions

  • the invention relates to a luminaire with an LED module (LED: light-emitting diode).
  • LED light-emitting diode
  • An LED module typically includes a circuit board and at least one LED disposed on that board.
  • the LED module is connected to an electrical voltage source, through which the at least one LED, a current can be supplied, so that the latter emits a light.
  • an electrical voltage source through which the at least one LED, a current can be supplied, so that the latter emits a light.
  • a user accidentally touches the circuit board or the at least one LED when operating the luminaire, ie when an electrical voltage is applied to the circuit board. Such a touch may result in the user experiencing an electric shock and / or damaging the LED module. Therefore, such lights are usually designed so that a corresponding protection against accidental contact of the LED module is given.
  • a cover for this purpose, which is arranged in front of the LED module accordingly.
  • the dimensions of the LED module are chosen in these known lights so that the usual standards with respect to compliance with air and creepage distances are met. Due to the fasteners used, therefore, certain minimum dimensions for the design of the LED module are considered. As a result, with respect to the size of the LED module and thus also on the size of the lamp overall limiting boundary conditions are given; in particular, corresponding minimum dimensions must be observed.
  • the invention has for its object to provide a corresponding improved luminaire;
  • the luminaire should have improved possibilities with respect to the design of their dimensions.
  • a luminaire which has a carrier element, an LED module which is arranged held on the carrier element and a cover element, which is arranged held on the carrier element.
  • the cover element, the LED module is arranged pressing against the support element.
  • the cover is arranged held via a latching connection to the carrier element, in particular only via the latching connection. This makes it possible to achieve that the cover element can be mounted particularly easily on the support element, in particular without the aid of a tool.
  • the cover is designed as an optical element. This makes it possible to dispense with a corresponding separate optical element. Thus, the number of components of the lamp can be reduced.
  • the LED module is held by holding parts on the carrier element, wherein the holding parts have surfaces which consist of an electrically non-conductive material. This also allows the air and creepage distances to be smaller. A particularly simple design is made possible when the holding parts are made of plastic.
  • the cover is viewed in a cross section, the LED module arranged encompassing. In this way, a particularly suitable or reliable contact protection can be achieved.
  • the cover is designed as a component with a profile shape. This is manufacturing technology advantageous.
  • this design is particularly suitable in the case of a luminaire with an elongated light output range, for example in the case of a continuous line luminaire.
  • the cover is designed as an extrusion profile.
  • particularly suitable optical properties of the cover element can be achieved, in particular in a production-advantageous manner.
  • the cover element preferably has, in a cross section which is normal to the profile shape, a lens area and two lateral arm areas, wherein the lens area is formed between the two arm areas.
  • the lamp is designed in the form of a strip light.
  • Fig. 1 shows a perspective sketch of an end portion of a lamp according to the invention.
  • the lamp is designed as a strip light.
  • the luminaire is overall long, so that it extends, for example, in a straight line along a longitudinal axis L and has a correspondingly elongate light-emitting region.
  • the lamp may be designed as a ceiling light, which is provided for a light output down.
  • the lamp could, however, for example, be designed as a pendant or floor lamp.
  • the luminaire has a carrier element 1, which may for example be designed as a profile part, which is arranged oriented parallel to the longitudinal axis L , as in Fig. 1 indicated. Furthermore, the lamp has an LED module 2, which is arranged held on the support element 1.
  • the LED module 2 comprises a circuit board 22 and at least one LED 23, here several LEDs 23, which are arranged on the board 22.
  • the circuit board 22 is arranged elongated and aligned parallel to the carrier element 1 or to the longitudinal axis L.
  • the LEDs 23 can - as in Fig. 1 indicated - for example, be arranged so that they extend along a straight line parallel to the longitudinal axis L.
  • the board 22 is arranged in the example shown with respect to their shape substantially designed as a plate and aligned horizontally oriented, wherein the LEDs 23 are arranged on a downwardly facing surface region of the board 22.
  • the carrier element 1 has a, in particular planely designed, downwardly facing surface area, which is provided for connection to the circuit board 22.
  • the board 22 and the LED module 2 is held by holding parts 4 on the support member 1, wherein the holding parts 4 have surfaces which consist of an electrically non-conductive material.
  • creepage distances and clearances can be designed to be particularly small and thus the entire LED module 2 can be designed with a particularly small size.
  • the entire luminaire can be made correspondingly small in consequence. In particular, this makes it possible to achieve a particularly slim appearance of the continuous line luminaire. Also can be produced by a correspondingly smaller design of the board 22, the LED module 2 basically cheaper.
  • the said holding parts 4 are also in Fig. 2 indicated by way of example, which shows a perspective sectional sketch of an area around the LED module 2 of the luminaire.
  • the holding parts 4 are designed as plastic elements.
  • a particularly simple mounting of the LED module 2 on the carrier element 1 is made possible when the holding parts 4 are arranged latching, in particular latching, on the carrier element 1. In particular, this can be achieved the LED module 2 can be mounted on the carrier element 1 without the aid of a tool.
  • the LED module 2 is arranged on the carrier element 1 without a metal holding means, in particular without a screw. This is also advantageous with respect to the framework conditions for the creepage distances and creepage distances to be complied with.
  • the lamp has a cover 3, which is arranged held on the support element 1.
  • the cover 3 is arranged such that it presses the LED module 2 against the support element 1.
  • a safeguard against unwanted loosening of the LED module 2 is formed by the carrier element 1.
  • the LED module 2 can be arranged in a particularly suitable manner on the carrier element 1, in particular without the aid of metal fastening or holding elements.
  • the abovementioned configuration of the connection with the holding parts 4 made of plastic represents a possible, as such, sufficient mechanical connection between the LED module 2 and the carrier element 1.
  • the cover 3 thus represents a backup for the LED module 2;
  • the cover 3 can be by the cover 3, the position of the board 22 in case of failure, for example, in a fracture of one of the holding parts 4, secure.
  • a fuse to prevent detachment of the LED module 2 from the carrier element 1 or a "crash" of the LED module 2 can be achieved by the cover element 3.
  • the cover 3 is held via a latching connection to the support element 1;
  • a particularly simple mounting of the cover 3 on the support element 1 is made possible.
  • the cover element 3 is held only on the latching connection to the support element 1.
  • a particularly simple assembly is made possible when the design is such that the cover 3 can be arranged on the carrier element 1 without the aid of a tool.
  • the cover 3 is designed as a component with a profile shape, wherein the cover 3 is arranged in particular oriented parallel to the longitudinal axis L.
  • the design as a profile part is accordingly particularly suitable in the case of a strip light.
  • this may be the cover 3 designed as an extrusion profile.
  • the cover element 3 viewed in a normal cross-section to the profile shape, has the lens area 31 in a middle area and two lateral arm areas 32, wherein the lens area 31 is formed between the two arm areas 32.
  • the arm regions 32 are particularly suitable for producing the latching connection between the cover element 3 and the carrier element 1.
  • shoulder surfaces 15 pointing upwards may be formed in the carrier element 1, which serve for supporting latching lugs 33 which are formed on the upper end regions of the arm regions 32 are.
  • the cover member 3 is symmetrical with respect to a vertical mirror plane passing through the LEDs 23. In this way it is possible that the cover 3 presses particularly evenly against the LED module 2 and thus secures particularly suitable.
  • the carrier element 1 furthermore preferably has two lateral wall regions 17, which extend downwards from the shoulder surfaces 15 and form as contact surfaces for the arm regions 32 of the cover element 3. In this way, a reliable positioning and a particularly simple production of the latching connection between the cover 3 and the support element 1 is possible.
  • the carrier element 1 can, as it were, have two "rear pulls" which are formed by the two lateral wall regions 17 and the shoulder surfaces 15.
  • the holder of the cover 3 on the support element 1 is preferably designed such that on the one hand a tool-free attachment of the cover 3 is made possible on the support member 1, on the other hand, however, a release of the cover 3 of the support member 1 only with considerable effort is possible, preferably only by at least two separate steps; As a result, corresponding standards can be met. In this way, a particularly reliable cover of the LED module 2 or sheathing of the LED module 2 is possible.
  • the cover element 3 preferably extends at least as far at both ends as the LED module 2, preferably beyond the LED module 2 in each case.
  • a reliable protection of the LED module 2 is also possible in this extension considered possible.
  • the luminaire is designed as a linear luminaire, it is of course possible to provide a plurality of correspondingly designed LED modules which are arranged in a row behind one another in the direction of the longitudinal axis L.
  • the LED module 2 is fixed to the support member 1, for example, with the holding parts 4 and in a subsequent second step the cover 3, again preferably without tools, on the support element is mounted.
  • the cover element 3 thus fulfills a total of several functions: it serves by sheathing the LED module 2 as contact protection, furthermore as a mechanical protection of the LED module 2 against unwanted detachment from the support element 1 and also as an optical element for influencing the LED Module 2 radiated light.
