Abstract

The invention discloses an arranging method of LEDs. The arranging method comprises the following steps of: building a virtual grid chessboard with M virtual transverse lines and N virtual vertical lines to form a plurality of transverse and vertical crossed nodes; putting a plurality of transverse LEDs onto the virtual transverse lines, wherein each transverse LED is positioned between two adjacent transverse crossed nodes, the anode end of each transverse LED is connected to the anode end of the adjacent transverse LED, and the cathode end of each transverse LED is connected to the cathode end of the adjacent transverse LED; putting a plurality of vertical LEDs onto the virtual vertical lines except the first and the least virtual vertical lines, wherein each vertical LED is positioned between the two adjacent vertical crossed nodes, the anode end of each vertical LED is connected to the anode end of the adjacent vertical LED, and the cathode end of the vertical LED is connected to the cathode end of the other adjacent vertical LED; and an alternating-current power supply is connected to the first and the last virtual vertical lines, and the LEDs can be powered by the alternating-current power supply directly so as to generate stable and smooth brightness.

Description

technical field [0001] The invention relates to a method for arranging light-emitting diodes, in particular to a highly expandable structure which is directly powered by an AC power supply and has a low-loss design and stable and smooth brightness. Background technique [0002] Currently, a light emitting diode (LED) is a widely used semiconductor light source, which has a positive terminal and a negative terminal. The LED mainly includes a PN junction, which is used as a light-emitting layer when the supplied direct current (DC) voltage exceeds the turn-on threshold (ie forward voltage). Therefore, LEDs require a DC power source rather than a traditional alternating current (AC) power source. For traditional AC power sources, such as mains or generator output power, an appropriate rectification device is usually used to convert the AC power into the required DC power, such as using a bridge composed of multiple diodes or a step-down circuit with inductive components.
