Illumination circuit having bypass circuit controllable according to voltage change of series circuit thereof |
摘要 |
An illumination circuit includes a series circuit including light sources connected in series between a high voltage node and a low voltage node, and break-protecting circuits. Each break-protecting circuit includes a control circuit and a bypass circuit. The bypass circuit is connected in parallel to at least one corresponding light source of the light sources. The control circuit is connected to the series circuit and the bypass circuit to detect a voltage change of the series circuit and control the bypass circuit to be in a conduct state or a blocked state according to the voltage change |
