<p>The present invention relates to the field of lighting, and specifically relates to a PCB of an LED lighting, comprising a driving power supply circuit, a control circuit, and an LED light, all having electronic components arranged on a same substrate. The electronic components of the driving power supply circuit, of the control circuit, and of the LED light are all surface-mount electronic components, while the electronic components of the driving power supply circuit and of the control circuit are arranged in non-occupied parts around the LED light. Also comprised is a temperature monitoring circuit signally connected to the control circuit, where a temperature detecting component of the temperature monitoring circuit is arranged in proximity to a logical operation CPU of the control circuit. The PCB of the LED lighting of the present invention has the driving power supply circuit, the control circuit, and the LED light all fabricated onto a same substrate, is of reduced manufacturing costs, and has a simplified manufacturing process and great stability.</p> |
