The first metal layer is plated on an outside of the substrate and does not include graphite. The second alloy layer is plated on an outside of the first metal layer and is synthesized from graphite and metal. The third metal layer is plated on an outside of the second alloy layer and does not include graphite. The fourth alloy layer is plated on an outside of the third metal layer and is also synthesized from graphite and metal.

Abstract: Disclosed is a lighting device with low-power consumption, including: a rectification circuit, a supply circuit of intelligent module, an intelligent module, a silicon controlled dimming circuit, a white light driving circuit, a white light lamp panel, a RGB driving circuit, and a RGB lamp panel. The above lighting device with low-power consumption can provide maintenance current through the silicon controlled dimming circuit. During operation of the white light driving circuit, the silicon controlled dimming circuit keeps working consistently. When the lighting function is turned off, the silicon controlled dimming circuit turns off the output and enters a standby state.
