Definitions

  • the invention relates to a lamp for vehicles, in particular a rear lamp, with a plurality of chambers each having a light source, which are arranged adjacent to one another.
  • a lamp for vehicles which is protected from damage by a protective grille.
  • a plurality of struts running in parallel are provided, which are fastened in a region of the body enclosing the lamp.
  • the struts of the grid extend at a distance from an upper side of the cover plate of the lamp.
  • Strips are provided for fastening the struts, a profiled first strip having a bore aligned with a bore in the body for the clamping retention of a bolt in the bore in the body.
  • a strip is provided, on which axially extending pins are integrally formed, which engage in a groove of a rubber-like strip, which is connected to the body by gluing.
  • a bracket of the lamp itself through this grid is not provided.
  • a lamp for vehicles is known from EP 0 795 718 A1, which has a plurality of chambers, in each of which a light source is arranged. However, the chambers are arranged in a common pot-shaped housing, the opening of which is covered by a cover plate.
  • a disadvantage of the known luminaire is that the rigid functions of the chambers, in particular the fixed design of the reflectors, determine the lighting functions and the distribution of the lighting functions within the housing.
  • the cover plate is non-positively connected to the housing. From DE 296 18 562 U1 a lamp for vehicles is known which provides a housing with a plurality of chambers each having a light source. The opening of the cup-shaped housing thus formed is closed by a cover plate.
  • Plug elements are provided on an outer edge of the housing, by means of which an attachment piece can be fastened.
  • the extension piece is preferably designed as a reflector.
  • the manufacturing outlay can hereby be reduced to the manufacture of a housing and an extension piece.
  • a disadvantage of the known luminaire is that with a symmetrical arrangement of the luminaire, differently shaped carriers are required to accommodate the housing and the extension piece.
  • the object of the present invention is therefore to develop a lamp for vehicles in such a way that, on the one hand, increased variability and, on the other hand, simplified interchangeability of the lamp is ensured.
  • the invention in connection with the features of the preamble of the main claim, characterized in that the chambers are each formed by lighting units with a pot-shaped housing having a light source, the opening of which is closed by a cover plate, and that a locking device is provided with Means for fastening the lighting units to a common support.
  • the advantage of the lamp according to the invention is, in particular, that a modular structure of a lamp is created by the provision of separate lamp units.
  • a certain lighting function is assigned to each lighting unit.
  • the lighting function is predetermined by the design of the lighting components, for example a reflector or cover plate, of the individual lighting units.
  • the arrangement of the lamp units within the lamp can advantageously be changed even after the lamp has been manufactured, so that there is a high degree of variability.
  • a locking device enables one or more lighting units to be easily Way can be removed or replaced.
  • the manageability of replacing a light source is particularly facilitated by the fact that after the light unit has been removed, the light source on the rear of the light unit can be removed and reinserted.
  • the cover plate does not have to be removed from the housing.
  • the locking device has a holding element which is fastened to the carrier and can be brought into an edge region of the lamp units in a locking position.
  • the holding element is elongated and extends along a longitudinal edge of the lamp.
  • the holding element is preferably formed in one piece and can thus serve as a terminating edge or decorative strip for the lamp. Due to the elongated design of the holding element, several lighting units can be unlocked or locked in a simple manner.
  • the holding element is designed as a U-shaped bracket, the free ends of which are angled to the carrier. As a result, the holding element can be moved into the locking position or unlocking position by pivoting about a pivot axis running parallel to the same.
  • the ends of the bracket are articulated on a back of the carrier. This creates a slight curvature of the pivoting path of the holding element when unlocking or locking, which simplifies handling.
  • the gravity of the holding element can be used to bring the latter into the locking position.
  • a safety element is assigned to the bracket, which, by fixing the bracket to the carrier, creates a clear locking position of the bracket and also enables the bracket to be securely held on the carrier.
  • the lighting units each have a contact element on a rear side thereof, which can be connected to a contact element of the carrier by a plug connection.
  • the contact element of the lighting unit is preferably designed as a plug-in element which can be latched to the second contact element of the carrier.
  • Appropriate guides of the body part comprising the lamp allow the lamp units to be clamped in the opening formed by the body part, so that a secure mechanical mounting is ensured. This can be done, for example, by spring tongues protruding from the body part and under tension.
  • the top of the holding element can be used to arrange an optical element on the same.
  • This can preferably be a reflector.
  • the optical element can also be designed as an active component, the elongated holding element serving as a cable duct for the supply of electrical energy.
  • the lighting units have the same dimension, so that a changing arrangement of the light functions within the lamp is ensured in a simple manner.
  • Figure 1 is a perspective arrangement of a lamp
  • Figure 2 is a side view of the lamp.
  • a lamp (1) shown in FIGS. 1 and 2 essentially consists of a carrier (2) and a plurality of lamp units (3) arranged on a front side of the carrier (2).
  • the lamp (1) is enclosed in a body opening, not shown, of a motor vehicle and is preferably used as a rear light.
  • the carrier (2) is cuboid, a rear wall (4) of the carrier (2) being rectangular.
  • a front wall (5) of the carrier (2) is concave.
  • the front wall (5) comprises a number of lighting units (3) arranged side by side.
  • the lighting units (3) are of identical design and each have a cup-shaped housing (6) which is closed by a cover plate (7).
  • the cover plate (7) can be designed as a clear, optically-free plate.
  • the cover plate (7) is slightly curved and is integrally connected to an edge of the housing (6).
  • the housing (6) has opposite parallel side walls (8) which are connected to one another by a convex rear wall (9).
  • the shape of the rear wall (9) corresponds to the shape of the front wall (5) of the carrier (2).
  • Each light unit (3) has a light source (not shown) and a reflector in the interior.
  • the lighting units (3) each perform different light functions independently of one another, for example a brake light, rear fog light, reversing light, etc.
  • each socket of a light source can be electrically and mechanically connected to a first contact element (10) of the housing (6).
  • This contact element (10) is arranged on the rear wall (9) of the housing (6) and with a second contact element (11) of the carrier (2) electrically and mechanically connectable.
  • This connection is preferably made by a plug-in connection or snap-in connection in the direction of an optical axis (12) of the lighting unit (3).
  • a locking device (13) is provided for securely attaching the lighting units (3) arranged next to one another on the carrier (2), which comprises a U-shaped bracket (14) which is rotatably mounted on the rear wall (4) of the carrier (2) .
  • the bracket (14) has two parallel legs (15), the free ends (16) of which are pivotally connected to an upper edge of the rear wall (4) of the carrier (2).
  • a holding element (17) At the front ends of the bracket (14) there is a holding element (17), which is designed as a retaining bar and in a locking position of the bracket (14) on an edge region of the lighting units
  • the holding element (17) extends along an upper edge region of the lighting units (3) and thus forms a transition from the lighting units (3) to the subsequent body part, not shown.
