Abstract:
1. A light emitting module, comprising: an anode control signal wiring group formed on a board, a cathode control signal wiring group formed on the board, a plurality of light emitting bodies formed on the board and arranged in a longitudinal direction of the board, a first connector on one end of the board and a second connector on the other end of the board, each connector being configured by a plurality of cathode terminals and at least one anode terminal, wherein the light emitting module, such that in each connection between two adjacent light emitting modules, the second connector of an upstream light emitting module is connected with the first connector of a downstream light emitting module, thereby being configured to be capable of a multi-level connection of at least three of the light emitting modules; the anode control signal wiring group includes a first anode wiring and at least one second anode wiring, one end of the first anode wiring being connected to one of the anode terminal of the first connector, and the other end of the first anode wiring being connected to one end of each of the light emitting bodies on the board, one end of the at least one second anode wiring being connected to the first anode wiring or another anode terminal of the first connector, and the other end of the at least one second anode wiring being connected to one of the at least one anode terminal of the second connector; the cathode control signal wiring group includes a first cathode wiring group including a plurality of first cathode wirings and a second cathode wiring group including a plurality of second cathode wirings; one end of each of the first cathode wirings is connected to one of the cathode terminals of the first connector and the other end of each of the first cathode wirings is connected to the other end of one of the light emitting bodies on the board; one end of each of the second cathode wirings is connected to one of the cathode terminals of the first connector, the other end of each of the second cathode wirings is connected to one of the cathode terminals of the second connector, and the second cathode wirings are not connected to the light emitting bodies on the board; the cathode terminals in the first connector to which the first cathode wirings of the first cathode wiring group are connected configure a first cathode terminal group; the cathode terminals in the first connector to which the second cathode wirings of the second cathode wiring group are connected configure a second cathode terminal group; a third cathode terminal group, defined by some of the cathode terminals of the second connector to which the other end of each of the second cathode wirings is connected, is physically located at the same position as that of the first cathode terminal group of the first connector of another light emitting module having a same or different number of light emitting bodies; and the physical position of the third cathode terminal group overlaps that of the first cathode terminal group, wherein the other end of each of some of the second cathode wirings is not connected to the cathode terminals of the third cathode terminal group, while the other end of each of a rest of the other second cathode wirings is connected to corresponding one of the cathode terminals in the second connector of the third cathode terminal group, and the second cathode wirings that are not connected to the cathode terminals of the third cathode terminal group defines a third cathode wiring group.
