Definitions

  • the invention relates to an optoelectronic component according to the preamble of the main claim.
  • Such a component is known from WO-A-8 910 607.
  • the entire component forms a flexible, illuminable sign and is constructed overall like a sandwich.
  • a conductive layer which is coated with phosphorus, is applied to a non-conductive substrate layer.
  • a conductive film is applied over the phosphor layer, on which there is a conductor track.
  • the conductor track and the conductive layer between the phosphor layer and the substrate are electrically contacted.
  • the entire arrangement is enclosed in a transparent encapsulation. This encapsulation is accommodated in a transparent protective housing such that a mask can be inserted between the encapsulation and the protective housing, on which symbols to be illuminated are left out.
  • elements to be illuminated such as switches, buttons and the like.
  • the like Simple to design, to reduce the manufacturing costs, to make separate cover elements unnecessary and to avoid light losses that had previously been accepted.
  • the body of the LED and the light-transparent element form a unit, so that no light losses occur.
  • any commercially available and correspondingly inexpensive LED can be used to a large extent.
  • the component which is designed completely with the symbol or in its contour as a symbol can be used directly be used in an actuating element of a switch, push button and the like, with the advantageous consequence that, in principle, no further measures need to be taken to hold the LED or to ensure that the light losses normally to be expected with a separate arrangement below one Actuator of a switch, button or the like. To be kept to an acceptable minimum.
  • the light-transparent element has at least one zone which is designed in the form of a symbol with respect to its externally visible contour, the part of the element surrounding the zone being non-light-transparent.
  • the element itself is wholly or partly formed by an actuating element of a switch, a pushbutton or the like, the body of the LED with the light-transparent zone of the element in the form of a symbol being initially used in one or more immediately successive injection molding process steps is produced and subsequently the non-light-transparent part of the element.
  • This configuration of the component allows on the one hand a very cost-effective producibility and on the other hand it enables high miniaturization, for example, of actuating elements of switches, buttons and the like, which can be illuminated at one or more points, for example the actuating elements of so-called window regulator switches in motor vehicles.
  • the light-transparent element can advantageously be white, which also applies to the design of the component in which only the zone is light-transparent is trained.
  • the zone can also advantageously have a predetermined other suitable, desired color.
  • a connection of the light-transparent element, which advantageously consists of plastic, to the body of the LED by injection molding can be carried out in large numbers in a particularly cost-effective manner.
  • connection between the light-transparent element and the body of the LED can be made by gluing.
  • the component 10 according to the invention is basically formed by an optoelectronic component with luminescent radiation-emitting properties, generally with a luminescent diode, light-emitting diode or, in short LED (Light Emitting Diode) is called.
  • a luminescent diode generally with a luminescent diode, light-emitting diode or, in short LED (Light Emitting Diode) is called.
  • the semiconductor diode is caused in a known manner to spontaneously emit luminescent radiation in the region of the pn junction, which is generally known and need not be described further here.
  • LEDs 10 are available in a wide variety of constructive configurations, so that the enlarged side view in FIG. 1 (approx. 10 times enlarged) is only to be understood as an exemplary representation, ie without a restrictive constructive character of the component 10 to the representation shown in FIG. 1.
  • the component 10 has, in addition to a body 12, which as a rule partially but also entirely consists of light-transparent plastic, has two connections 11 which serve for the voltage supply in a known manner.
  • the light-transparent part 13 of the body 12 of the component 10 is at least partially surrounded by an at least partially light-transparent element.
  • the light-transparent part 13 of the body 12 and the element 14 lie on top of one another in such a way that the two elements are in contact with one another, with the exclusion of a gap between their surfaces.
  • Light 16 can thus directly enter the light-transparent element 14 on the outlet side of the body 12 and, as indicated in FIG. 1, leave it to the outside.
  • the light-transparent element 14 itself can consist of injection-moldable plastic, so that it can be used directly, for example, using an injection molding process can be sprayed onto the light-transparent part 13 of the body 12 and thus a unit of light-transparent element 14 and the actual optoelectronic component 10 is formed quasi by this process.
  • the actual optoelectronic component has been omitted for reasons of clarity.
  • the light-transparent element 14 is designed such that it is designed in relation to its externally visible contour in the form of a symbol 15, here in the form of an arrow, which is apparent from FIG. 3, the one shows rotated by 900 compared to the representation of FIG. 2 in the plan view, results.
  • the light-transparent element 14 can be white, for example, so that to a certain degree a white light portion of the light 16 leaving the light-transparent element 14 is formed.
  • any predetermined colors can be selected in the formation of the light-transparent element, regardless of whether an embodiment according to FIG. 1 or according to FIGS. 2 and 3 is selected.
  • the light-transparent element 14 can also be designed in such a way that it has at least one zone which, in terms of its externally visible contour, is in the form of a symbol 15 is formed, while the part of the element 14 surrounding the zone is not transparent to light, ie that would be the area of the element 14 in the illustration according to FIG. 3 which lies outside the symbol 15. It is then also with this configuration possible that the light-transparent element 14 formed by the zone, ie the actual symbol 15, downward, cf. Fig. 2, extended to the component 10 (not shown), so that the component 10 emits its light directly into the light-transparent zone of the element 14, ie in the area of the symbol 15, while the part surrounding the zone is opaque.
  • the shape of the element 14 shown in the figures can also be of any suitable design, ie the shapes shown only schematically symbolize the element 14, without the design of the element 14 is limited to this.
  • the element 14 can form the actuating element of a so-called window lifter switch, as is used, for example, in automobile construction for lifting and lowering the windows in motor vehicles for actuating them.
