Spectrum-variable light-adjustable LED lighting system

The utility model belongs to the field of LED lighting and particularly relates to a spectrum-variable light-adjustable LED lighting system. The spectrum-variable light-adjustable LED lighting system comprises a lighting system, a Zigbee transmitting module, a PC computer and a spectrograph, and is divided into multiple channels inside. Each channel is provided with an AC/DC (alternate-current/direct-current) converter. An LED lamp set of a certain wave band, a corresponding PWM (pulse width modulation) control module and a Zigbee receiving module are mounted in each channel. Each LED lamp set comprises a heat radiator, an LED lamp strip and an optical diffusion plate. The spectrum-variable light-adjustable LED lighting system is simple in structure and novel in concept. By the aid of the Zigbee protocol based wireless communication network, spectrum can be variated and light can be adjusted without excessive cables. Besides, fine-adjustment control of the spectrum can be realized by a feedback mechanism of the spectrograph, different light environments can be simulated conveniently so that LED intermediate vision and light biological safety experiments can be realized.
