Definitions

  • the invention relates to a transmitter element with a housing and a display device
  • Such a transmitter element is generally used to generate signals for an electrical control system, which in turn is part of a machine or system.
  • the signal generation in the encoder element can be based on various principles, e.g. on an inductive or capacitive detection principle, in which case the transmitter element is designed as an inductive or capacitive proximity switch.
  • a sensor delivers a switching command, which is then implemented by the transmitter element and passed on to the control system, for example.
  • the switching command converted into a switching state can be made visually recognizable by a display device.
  • a further display device can be used to visually represent an operating state.
  • a wide variety of display devices can be used to display the switching and / or operating state of the transmitter element.
  • a display device is understood to mean, inter alia, a device by which an optical signal for recognizing the switching and / or operating state is output as information or a message.
  • a display device for vehicles has a housing in which a light source and a reflector assigned to this light source are arranged.
  • a display device for vehicles is shown in the drawing on page 1 in a cross section from above.
  • the FIG has a housing which is formed with a boundary wall in which a light source is mounted in a lamp holder, which is designed here as a flashing light for a direction indicator on the vehicle.
  • another boundary wall is visible in the cross section of the signal lamp, which forms a reflector for the light source.
  • the open sides of the housing are covered against the outside of the vehicle with a transparent cover plate in the direction of a side of the vehicle and on the front of the vehicle.
  • the reflector is arranged behind the turn signal in the longitudinal direction of the vehicle and seen from the vehicle side, so that its alignment acts as a reflector for the turn signal.
  • the reflector can deflect the incident light rays from the flashing light towards the front of the vehicle.
  • a light reflection element reflects light which is emitted by the light emitting diodes in different colors and as
  • Signal light is configured in order to indicate the status of machines, danger and the like.
  • conventional device status detectors generally also called display devices - are known from practice. These are usually designed as conventional light-emitting diodes and are arranged in the respective device housing such that the lenses of the light-emitting diodes are either flush with the housing or protrude through the housing wall.
  • Switching and / or operating states of the corresponding devices are displayed optically.
  • the invention is therefore based on the object of specifying a transmitter element with a display device in which better detection of the switching and / or operating states is to be achieved.
  • the transmitter element with a housing and a display device
  • a light source which essentially has a first emission direction for light which can be emitted by the light source, the light source comprising a light-emitting diode, and
  • Reflectors which serve to deflect part of the direct light of the light source into a second and a third emission direction, the first, second and third emission directions being directed differently,
  • SMD Surface Mounted Device
  • parts of the direct light can be deflected in a targeted manner by the reflectors, so that the best possible recognizability is achieved while at the same time saving additional or larger light sources.
  • the integration of the display device in a housing corner gives a design advantage, with no bulbs that disturb the design of the housing being necessary.
  • Two reflectors are advantageously arranged below a transparent outer wall, which is formed by a corner of the housing.
  • the two reflectors and the outer wall are formed by one body, the
  • Body has flat surfaces that serve as reflectors. Such a structural design and arrangement of elements is particularly space-saving and inexpensive to implement.
  • the reflectors are expediently arranged at a predetermined angle of 45-100 °, preferably 90 °, to one another.
  • the reflectors are arranged at an angle of 20-70 °, preferably 30-50 °, in particular approximately 35 °, to the path of the emitted direct light of the first emission direction.
  • 1 shows a transmitter element with an integrated display device
  • the encoder element 1 in FIG. 1 has a housing 3 on which a display device 5 is arranged.
  • the display device device 5 is integrated in the present case in the corner of the housing 3.
  • the connection or mechanical fastening of the display device 5 to the housing 3 is carried out using means known in the art, for example by gluing, by ultrasonic welding or by a plug-in or snap-in connection.
  • the display device 5 is advantageously shaped such that a flush outer contour is provided on the housing 3. If necessary, the display device can also be raised, protruding from the housing shape.
  • the display device 5 integrated in the housing 3 has a corner shape. Thus, on the housing 3, three adjacent sides are illuminated by the display device 5.
  • the display device 5 comprises on the one hand a body 7 designed as a transparent window, which has reflectors 11, and on the other hand has a light source.
  • FIG. 2 shows the body 7 of the display device 5 in a spatial representation from an inside view.
  • the body 7 has an outer wall 9, which forms a transparent window, flat surfaces 13 and a reflector base 15.
  • the core 7 is shaped in its core in the manner of a truncated pyramid, the flat surfaces 13 serving as reflectors 11. When light is radiated through the reflector base 15, the effect of the boundary layer mirroring is then used.
  • the body 7 can be made of materials such as glass, translucent plastic or materials and / or materials with low light attenuation.
  • the display device 5 comprises a printed circuit 19 or circuit board of a transmitter electronics, not shown here, which is in operative connection with the light source 17.
  • the light source 17 is placed on the printed circuit 19.
  • the light source 17 is designed as a light emitting diode.
  • the light source 17 borders on the reflector base 15, which forms a structural unit with the flat surfaces 13.
  • the flat surfaces 13 are inclined towards the center of the reflector base 15 at an angle of ideally 20-70 °, preferably 30-50 °, in particular approximately 35 °.
  • the flat surfaces 13 are offset from one another by approximately 90 °.
  • the plane surfaces 13 serving as reflectors 11 are arranged inside the body 7 below the outer wall 9.
  • the encoder element 1 is preferably used in a proximity switch. Starting from a detection area of a proximity switch that an object is approaching, a sequencer is triggered in the transmitter element 1, the result of which is output as a switching command. This switching command is used, among other things, to control the light source 17, here an SMD light-emitting diode. The control takes place electrically and causes the light source 17 to light up.
  • the light of an SMD light-emitting diode essentially consists of direct light in the first emission direction 23, which is emitted orthogonally to the surface of the light source 17.
  • the direct light in the first radiation direction 23 radiates through the reflector base 15 on the one hand in a straight line and on the other hand onto those protruding into the path of the direct light 25 Flat surfaces 13.
  • the direct light is deflected at a specific angle on the flat surfaces 13. This angle is between 20-70 °, preferably 30-50 °, in particular approximately 35 °.
  • the reflected light in the second radiation direction 29 and in the third radiation direction 33 thus emerges from the outer wall 9 at the desired angles. So light emerges from the outside of the body.
  • the light source 17 can also e.g. be designed as a conventional light-emitting diode. These can be arranged inside the housing corner below the outer wall 9 and below the reflectors 11 or also deeper within the housing 3 of the transmitter element 1.
  • the light can be deflected via individual, separately or separately arranged reflectors, which can also consist of several combined or differently positioned mirrors.
  • the reflectors can also be arranged inversely to the geometry described above or as
  • Concave mirrors also lead to the desired illumination of a housing corner.
