Abstract

The invention discloses a matrix type LED light source circuit board. At least two rows and two columns of LED light-emitting diodes are installed on the printed circuit board; the LED light-emitting diodes in each column are arranged in the same polarity direction and connected in series Together, one electrode of the LED light-emitting diode at the front end of each column is an electrode connection end of the power supply, and one electrode of the LED light-emitting diode at the end of each column is the other electrode connection end of the power supply; the LED light-emitting diodes of each row are two The stage tubes are grounded and connected in parallel with the same polarity. When the present invention is used, when any LED light emitting diode is damaged, other LED light emitting diodes will continue to receive power from the bypass, and will continue to work without being affected by the damaged LED light emitting diode. Therefore, the present invention not only has the advantages of long service life, good working stability, and high utilization rate of LED light-emitting diodes, but also has the advantages of simple structure, easy manufacture, and low use cost.

Description

technical field [0001] The invention relates to a matrix type LED light source circuit board, which belongs to the technical field of LED light-emitting diode lighting. Background technique [0002] At present, LED light-emitting diodes have been widely used as light sources for lighting because they have the advantages of energy saving, high brightness, and small size as light sources. However, the LED light source circuit boards in the prior art often use a plurality of LED light-emitting diodes connected in series as a group of light sources to be connected in the circuit as a lighting source, or connect such a plurality of LED light-emitting diodes in series A group of light sources are connected in parallel and used as lighting sources. Although the LED light source circuit board with this connection structure has the advantage of being able to easily produce different power lighting sources, in use, when only one LED light-emitting diode in each group of LED light sou...
