Abstract
The present invention provides a lighting device having an energy conversion module, comprising a lamp and at least one energy conversion module. The lamp includes a shade and a lamp tube. The lamp tube is disposed beneath the shade, and the inner wall surface of the shade can reflect light from the lamp tube. The energy conversion module is configured inside the shade or disposed on a lamp grid to receive light energy and convert it into electrical energy. As such, the lighting device can give light to photovoltaic cells in the environment so that electrical energy is generated. The object of converting part of the light energy into electrical energy for further utilization can thus be achieved.
