[0070] will refer to Figures 1 to 3 A light emitting module device according to a first embodiment of the present invention will be described. figure 1 The configuration of the light emitting module device according to the first embodiment is shown. The light-emitting module device 1 includes a plurality of light-emitting modules 2 and a module driving circuit 4 that supplies the light-emitting modules 2 with electric power required for the light-emitting modules 2 to emit light via a power line 3 . The light emitting modules 2 are arranged in a matrix (in a grid-like manner) to form rows and columns. For example, the lighting modules 2 are arranged in a 4 by 4 matrix. Multiple light emitting modules 2 share the power line 3 . In addition, a switch 31 and a switch 32 that turn on or off current conduction to each light emitting module 2 by an opening / closing operation are provided on the power line 3 . The module drive circuit 4 performs opening / closing operations of the...

Abstract

To control light emission of light-emitting modules, individually, at low cost in a lighting apparatus having a plurality of the light-emitting modules. The lighting apparatus 1 includes a plurality of the light-emitting modules 2, a control unit 3 that sends a control signal to the light-emitting modules 2 to control the light emission of the light-emitting modules 2, and a power feeding unit 4 for feeding power to the light-emitting modules 2. The light-emitting modules 2 are arranged in a lattice form so that they are placed in rows and columns. The lighting apparatus 1 has communication lines 5 and 6, each connecting the control unit 3 and the light-emitting modules 2 in each row and column, and switches 7a-7d and 8a-8d for switching the communication lines 5 and 6 between a conducting state and a non-conducting state. The control unit 3 controls the conduction / non-conduction of the switches 7a-7d and 8a-8d to select specific light-emitting modules 2, and sends the control signal to the selected light-emitting modules 2. By this method, there is no need to provide an ID for selection to the light-emitting modules 2.

Description

technical field [0001] The present invention relates to a light emitting module device for individually controlling a plurality of light emitting modules, a light emitting module used in the light emitting module device, and a lighting device having the device. Background technique [0002] Figure 17 The configuration of a conventional light emitting module device is shown. In the light emitting module device 100, the light emitting modules 101 are arranged in a matrix shape, the light emitting modules 101 adjacent to each other are connected via the connection point 102 for transmitting electric power, and the terminal of the power line 103 is attached to a row of light emitting modules 101 located at the end device 104. A control device (not shown) of each of the light emitting modules 101 adjusts the amount of light emitted by the light emitting modules 101 by itself. When the terminal device 104 supplies power to the light emitting modules 101, the power is sequential...
