Claim Text:
1. A light emitting diode system applied to an alternating current power supply apparatus, the light emitting diode system comprising: a first light emitting diode apparatus; and a second light emitting diode apparatus electrically connected to the first light emitting diode apparatus, wherein the first light emitting diode apparatus comprises: an alternating-current-to-direct-current and light-controlling unit electrically connected to the alternating current power supply apparatus; a plurality of first light emitting diode modules electrically connected to each other in series, a first of the first light emitting diode modules electrically connected to the alternating-current-to-direct-current and light-controlling unit, a last of the first light emitting diode modules electrically connected to the alternating-current-to-direct-current and light-controlling unit; and a first connector electrically connected to the alternating-current-to-direct-current and light-controlling unit and the last of the first light emitting diode modules, and arranged after the last of the first light emitting diode modules, wherein the second light emitting diode apparatus comprises: a second connector connected to the first connector; a signal-converting unit arranged after the second connector and electrically connected to the second connector; and a plurality of second light emitting diode modules electrically connected to each other in series and arranged after the signal-converting unit, a first of the second light emitting diode modules electrically connected to the signal-converting unit, a last of the second light emitting diode modules electrically connected to the signal-converting unit, wherein the alternating current power supply apparatus outputs an alternating current power to the alternating-current-to-direct-current and light-controlling unit; the alternating-current-to-direct-current and light-controlling unit converts the alternating current power into a first drive direct current power; the alternating-current-to-direct-current and light-controlling unit outputs the first drive direct current power and a light-controlling signal to the first of the first light emitting diode modules; then the first drive direct current power and the light-controlling signal are transmitted to the other first light emitting diode modules to control colors and intensities of the first light emitting diode modules; wherein the alternating-current-to-direct-current and light-controlling unit further independently outputs a second drive direct current power to the first connector; the last of the first light emitting diode modules sends the light-controlling signal to the first connector; the first connector sends the second drive direct current power and the light-controlling signal received by the first connector to the second connector, and then the second connector outputs the second drive direct current power and the light-controlling signal to the signal-converting unit; the signal-converting unit outputs the second drive direct current power and the light-controlling signal to the first of the second light emitting diode modules; then the second drive direct current power and the light-controlling signal are transmitted to the other second light emitting diode modules to control colors and intensities of the second light emitting diode modules; and wherein the first light emitting diode apparatus is connected to the second connector through the first connector, and then is connected to the second light emitting diode apparatus in series through the second connector.
