Lighting device utilizing mixed light emitting diodes

摘要

A lighting device with mixed LEDs for cultivating young plants. The lighting device comprises a lamp set, a plurality of light modules, a waveform generating module and a control module. The light modules can be selectively disposed on the lamp set. Each light module comprises a plurality of mixed light emitting diodes with various arrangements. The waveform generating module is electrically connected to the light module mounted in the lamp. The control module houses a waveform database comprising preset waveform data for different light modules, such that the control module can directs the waveform generating module to provide power of different waveforms according to each light module mounted on the lamp set and corresponding plants.
