Abstract: This paper launches novel materials of LED with ocean battery. Ocean battery employs sea water existing by the nature as energy materials to drive LED lamp lighting. The analysing methods are thermal-, electric- and illumination-performance experiments to discuss the novel green illumination techniques. Ocean battery and LED are all DC components, there is no energy loss of current converter between them, and the ocean battery has more electricity in LED illumination. Vapour chamber (VC) and aluminium (AL) materials are assigned to be the LED PCBs. Results show that the effective thermal conductivity of the VCPCB is many times higher than that of the ALPCB, proving that it can effectively reduce the temperature of the LED and obtain more uniform luminance. And the output voltage and LED lighting start unstable resulting from the air bubble of ocean battery slight vibration.
Keywords: ocean batteries; seawater; LED lamps; lamp lighting; vapour chamber; VCPCB; green illumination; aluminium; LED PCBs; printed circiut boards; thermal conductivity; temperature reduction; uniform luminance; output voltage.
