The first and second constant voltage layers are connected to a power supply respectively through two power connection points. The first constant voltage layer has at least one insulating zone. Each insulating zone has a light-emitting unit formed therein. One electrode of the light-emitting unit is connected to the first constant voltage layer, and the other electrode thereof is connected to the second constant voltage layer through a conducting wire. When the power supply outputs a low voltage to the first constant voltage layer, resistance values everywhere on the first constant voltage layer are identical. Accordingly, given any distance between a light-emitting unit and a corresponding power connection point, lighting efficiency of the light-emitting unit is not affected and effective power utilization can be ensured.
