In this study, we used two-step synthesis method to prepare nano-coating containing multi-walled carbon nanotubes (MWCNTs) of different concentrations and applied the MWCNTs to heat dissipation for the projection lamp fixtures. We quantitatively coated the nano-coating on the inner surface of the housing of the fixture and evaluated its effects on the internal temperature, power consumption, and luminous output of the fixture for different conditions. The results show that both concentration of the MWCNT nano-coating and the projecting angle of the fixture affect the internal temperature and power consumption. With the MWCNT nano-coating of concentration at 1.328 wt.% and the projecting angle of 0°, the internal temperature of the fixture adopting the halogen lamp and that adopting the LED lamp reduce 5.4% ± 2.1% and 3.2% ± 2.1% at most, respectively; the power consumption reduces 12.9% ± 2.1% at most for the LED lamp; the luminous output has no significant difference for either the halogen or LED lamp. This study demonstrates MWCNT Nano-coating has great feasibility for heat dissipation of the lighting fixture. Further, this concept can also be applied to the cases requiring non-contact heat dissipation. Therefore, this study can widely contributes to energy saving and carbon emission reduction.
