Claim of US Patent No. 10,143,057

1. A board-mounted parallel circuit structure with efficient power utilization, comprising:a first substrate having a first constant voltage layer, wherein the first constant voltage layer has: a first power connection point formed on one edge portion of the first constant voltage layer and multiple insulating zones formed on the first constant voltage layer;
a second constant voltage layer having a second power connection point formed on one edge portion of the second constant voltage layer;
a power supply having a positive output terminal and a negative output terminal and outputting a power at a voltage range of 2.5 volts (V) to 3.5 volts (V); and
multiple light-emitting units disconnected from each other but each light-emitting unit connected separately in parallel with the power supply, with each light-emitting unit being a light-emitting diode (LED) unit implemented by an LED core technology and formed within a corresponding insulating zone and having a positive terminal and a negative terminal,
wherein the positive terminal of each light-emitting unit is formed on an edge of the corresponding insulating zone and is electrically connected to the first constant voltage layer,
wherein the negative terminal of each light-emitting unit is formed on a position in the corresponding insulating zone and is electrically connected to the second constant voltage layer through a conducting wire,
wherein the first constant voltage layer is electrically connected to the positive output terminal of the power supply through the first power connection point,
wherein the second constant voltage layer is electrically connected to the negative output terminal of the power supply through the second power connection point, and
wherein the positive terminal of each of the multiple light-emitting units are connected in parallel to the positive output terminal of the power supply through the first constant voltage layer and the negative terminal of each of the multiple light-emitting units are connected in parallel to the negative output terminal of the power supply through the respective conducting wires and the second constant voltage layer,
wherein each insulating zone further has a conducting layer formed within the insulating zone and electrically connected between the negative terminal of the light-emitting unit and the conducting wire,
wherein the first substrate is rectangular comprising two long sides and two short sides,
wherein the multiple insulating zones are formed on the first constant voltage layer in a direction along the two long sides,
wherein an area of the first substrate expands in directions along the two long sides and the two short sides of the first substrate for the multiple insulating zones to be arranged along the two long sides and the two short sides of the first substrate to form an array of insulating zones with each insulating zone having a corresponding light-emitting unit formed within the insulating zone of the array of insulating zones,
wherein when the power supply outputs the power to drive the multiple light-emitting units, an identical voltage drop across the multiple light-emitting units on the first substrate is generated and resistance values everywhere on the first constant voltage layer are the same.
