Abstract

A lighting device includes a light holder component and a light source component. The light holder component includes a wireless power supply module. The wireless power supply module has a first magnetic element. The light source component includes at least one light source and a wireless electric receiving module. The light source is electrically connected to the wireless electric receiving module. The wireless electric receiving module has a second magnetic element. The second magnetic element is attracted to the first magnetic element to cause the light source component to dispose on the light holder component.
