Abstract
An illuminant device designed to activate a light source selectively in a plurality of lighting modes. The illuminant device includes a plurality of circuit boards having thermal conductivity and a plurality of lighting circuits each of which is operable to activate the light source in a selected one of the lighting modes. The lighting circuits are mounted on the circuit boards so that when the light source is being activated, the circuit boards will be different in temperature thereof from each other due to heat generated in at least one of the lighting circuits which is activating the light source. The illuminant device also includes a connector which couples the lighting boards together to transfer the heat therebetween, thereby enhancing the dissipation of the heat.
