The present invention discloses an H-bridge dimming and color temperature adjusting two-line output circuit and an LED dimming power supply. The H-bridge dimming and color temperature adjusting two-line output circuit includes a first signal generator U1, a second signal generator U2, a first switch transistor Q1, a second switch transistor Q2, a third switch transistor Q3, and a fourth switch transistor Q4. Through the above structure, it is possible to achieve two-line dimming and color temperature adjustment without distinguishing between positive and negative electrodes. The H-bridge dimming and color temperature adjusting two-line output circuit has the advantages of simple circuit connection, fewer devices, low cost, stable performance, and smooth dimming.
