Abstract
A light-emitting system comprises: a first power input terminal and a second power input terminal; an insulating substrate; a first light-emitting-diode string formed on the insulating substrate comprising at least three light-emitting diodes placed sequentially in a first direction to allow a current flow through the at least three light-emitting diodes of the first light-emitting-diode string generally in the first direction; a second light-emitting-diode string formed on the insulating substrate comprising at least three light-emitting diodes placed sequentially in a second direction to allow a current flow through the at least three light-emitting diodes of the second light-emitting-diode string generally in the second direction; a third light-emitting-diode string comprising at least three light-emitting diodes placed sequentially in a third direction to allow a current flow through the at least three light-emitting diodes of the third light-emitting-diode string generally in the third direction.
