Abstract:
An LED array comprising:a signal interconnection board having signal interconnections;a plurality of LEDs each connected to corresponding terminals of said signal interconnections of said signal interconnection board, said plurality of LEDs being arranged in array on a first plane of said signal interconnection boards;positive and negative power supply metal plates connected to a power supply at first ends thereof and to said signal interconnections of signal interconnection board at second ends thereof, said positive and negative power supply metal plates being arranged on a second plane of said signal connection board; andat least one capacitor provided between said positive and negative power supply metal plates, said at least one capacitor has a capacitance C meeting equation:C.gtorsim.(K+I)(VO.times.t)where VO is a power supply voltage for driving said plurality of LEDs at an ordinary state, I is total current at the time of turning said plurality of LEDs on, t is a period of time in which voltage lowered instantly at a time of turning said plurality of LEDs on is restored to be the voltage VO, and K is a constant.
