Abstract
A lamp device includes a controller, a plurality of light-emitting elements, a plurality of current conversion modules and an interpretation module. The controller is configured to output a dimming signal. The current conversion modules are coupled to the light-emitting elements and configured to control the light-emitting elements to emit light. The interpretation module is coupled to the current conversion modules and configured to output, according to a comparison table, a plurality of control signals corresponding to the dimming signal to the current conversion modules respectively. The light-emitting elements are different in a luminous property, and one of the current conversion modules is configured to output a feedback signal to the controller.
