<p>An LED drive, comprising: a power supply unit (1), a power supply control unit (2), and an activation protection unit (3); the power supply unit (1) supplies power for a load (501) when the LED drive is connected to the load (501); the power supply control unit(2) is connected to the power supply unit(1) and controls a switching element(201) of the power supply unit(1); the activation protection unit(3) is connected to the power supply control unit(2) and activates the power supply unit (1) via a connection with the load (501). The LED drive can be activated only when being connected to the LED load (501), thus solving the problem of an electric connection failure of the LED load (501) in the LED drive circuit, thereby making the entire LED drive and LED load (501) safer.</p> |
