<p>The present invention relates to an LED lighting circuit including a protection unit and a substrate including the same, more particularly, to an LED lighting circuit including a protection unit and a substrate including the same, in which protective resistors Rp are installed in parallel in each LED chip or at least one LED chip to prevent the LED from being damaged by externally induced currents or sudden changes in a power source, and an electrical connection and heat dissipation are realized by using only a single surface pattern of a printed circuit board. The present invention provides an LED lighting circuit including a protection unit and a substrate including the same, the LED lighting circuit characterized in that, with regard to a string formed by serially connecting an n number of LED chips (LED1, LED2 to LEDn, LED(n+1) to LEDx) and a configuration where a y number of the strings are connected in parallel to a stabilizer, protective resistors Rp are connected to each LED chip or at least one LED chip in parallel.</p> |
