DETAILED DESCRIPTION

(4) The following detailed description refers to the accompanying drawing that show, by way of illustration, specific details and embodiments in which the disclosure may be practiced.

(5) FIG. 1 shows, in the center at the top, a light-emitting element 101 in an exemplary view from below of a base 102 of the light-emitting element. In addition to the outlined components, the light-emitting element 101 has further components, for example at least one lamp, in particular a semiconductor light-emitting element, a light-emitting diode (LED) and contact elements on the base 102 for the application of a current or a voltage.

(6) The light-emitting element 101 can be inserted with its base 102 into variously configured sockets 103, 104, as is outlined at the lower left and right in FIG. 1. The sockets 103, 104 differ from one another in that, for example, they provide and apply different voltages to the contact elements of an inserted light-emitting element 101. By way of example, the first socket 103 provides a voltage of 220 V and the second socket 104 provides a voltage of 110 V.

(7) In order to prevent accidental insertion of the wrong light-emitting element, said sockets 103, 104 are differently coded. The coding consists of cutouts being mating coding elements 107, 108 or 109, which are formed in the inner circumference of the receiving area of the sockets 103, 104. When such a light-emitting element 101 is inserted, coding elements 105, 106 engage, in particular in a precisely fitting manner, in the mating coding elements 107, 108. By way of example, the coding elements 105, 106 protrude as pin-like projections from the outer circumference of the base 102.

(8) In this case, a first pair consisting of such a coding element 105 and such a mating coding element 107 is used to align the light-emitting element 101 to be inserted in a defined position of the light-emitting element 101 with respect to the socket 103 or 104. At least one further pair consisting of such a coding element 106 and such a mating coding element 108 is arranged on the circumference of the base 102 and on the inner circumference of the socket 103 offset with respect to the first pair at another defined position on the circumference, as is outlined at the lower left in FIG. 1. As a result, normally actually only one light-emitting element 101 such as this can be inserted with its base 102 into the socket 103, which, in terms of the functionality of said light-emitting element, in particular the voltage, matches the functionality of the socket 103. The position of the second pair consisting of the coding element 106 and the mating coding element 108 is along a second orientation line 111 which is offset by a first angle with respect to a first orientation line 110 which leads through the first pair consisting of the coding element 105 and the mating coding element 107 and the center of the socket.

(9) In the case of the socket 104 at the lower right in FIG. 1, a second pair consisting of a coding element and a mating coding element 109 is also provided on the circumference of the base and on the inner circumference of the socket 104; however, this is provided at another position, such that consequently another functionality, in particular voltage, of the light-emitting element can be coded. The position of the further provided second pair consisting of the coding element and the mating coding element 109 is along a third orientation line 112 with respect to the first orientation line 110 and is not the same as the second orientation line 111.

(10) In order to enable the insertion of the same light-emitting element 101 into this second socket 104, too, the coding element 106 is adjustably arranged on the base 102. In particular, the coding element 106 can be pressed in and thus also inserted into the socket 104, as is outlined at the lower right in FIG. 1. In order to bring the pressed-in or pushed-in coding element 106 into the original position again once the light-emitting element 101 has been removed from the socket 104, said coding element can be embodied in an elastic way (for example with a spring).

(11) In order that the light-emitting element 101 is not damaged during insertion into the socket 104 or that the functionality of the light-emitting element 101 is ensured, the voltage for operating the light-emitting element 101 is adapted on the basis of the state of the coding element 106. When the coding element 106 is pressed in, a changeover to another supply voltage for the light-emitting element 101 can occur.

(12) For the purpose of changing over, the coding element 106 is designed, for example, as a switch which, depending on the switching state, influences an electronics system 114 or circuit of the light-emitting element 101. By way of example, voltage dividers or circuit blocks can be switched in a different way in the circuit depending on the switching state of the switch 106. The electronics system 114 effects different modes for operating the light-emitting element 101 at different voltages.

(13) FIG. 2 shows a modified light-emitting element 201. Said modified light-emitting element has, in addition to the adjustable coding element 106, a further adjustable coding element 202. Both coding elements 106, 202 are connected to the circuit 114.

(14) Owing to the use of the light-emitting element 201, different evaluable operating modes occur on the basis of the positions of the coding elements 106 and 202. If two states (on/off) are possible per coding element 106, 202 then, in total, four discernible operating modes arise from two coding elements. Thus, by means of n coding elements, 2.sup.n states can be coded.

(15) Alternatively, it is possible for coding elements to be embodied as changeover switches, that is to say that a mechanical coupling between coding elements occurs, with the result that the state of one coding element influences the state of the other coding element.

(16) Further Advantages:

(17) For example, alternating coding elements may also be used. When the adjustable coding element of a first variant is pushed in, the other coding element, which is also adjustable and is according to an adjustable variant for a socket having a mating coding recess which is positioned differently, is automatically and, in particular, mechanically pushed out.

(18) According to another configuration, the coding element can also not be pushed in but folded away along an axis, for example parallel to the plane of the drawing.

(19) The coding element may also be movably mounted and is, for example, shifted from the mating element coding position of the mating coding element 109 of the socket 104 to the mating element coding position of the mating coding element 108 of the first socket 103 during or before insertion into the socket 103.

(20) While the disclosed embodiments have been particularly shown and described with reference to specific embodiments, it should be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the disclosed embodiments as defined by the appended claims. The scope of the disclosed embodiments is thus indicated by the appended claims and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced.
