A system for electrically connecting at least one light source to a system for supplying electrical power, wherein the connecting system comprises a lead frame able to be electrically connected to a system for supplying electrical power, the lead frame including at least one connecting terminal and at least one connecting means allowing the connecting terminal of the lead frame to be electrically connected to the light source, the connecting terminal and the connecting means being able to electrically connect the light source to the lead frame, thereby allowing the light source to be placed away from the lead frame.

Lighting circuit
11350505 · 2022-05-31 · ·

A semiconductor light source includes multiple light-emitting elements coupled in series. A driving circuit receives an input voltage, and supplies a driving current to the semiconductor light source. A bypass circuit is coupled to a part of the multiple light-emitting elements. When a low-voltage state occurs, the bypass circuit is set to the enabled state, thereby bypassing the driving current. An auxiliary power supply circuit is coupled in series with the part of the multiple light-emitting elements. When an expected current does not flow through the auxiliary power supply circuit after the bypass circuit is set to the disabled state, a judgement unit judges that an open-circuit fault has occurred in the part of the multiple light-emitting elements.
