ABSTRACT
The industrialization have accelerate the economic development and improved living condition, however, the side effect of convenient modern life reflects in excessive consumption of gasoline energy, climate change and global warming. As the concept of environmental protection and cherish scare resources rise, the technology development of energy saving and green product have become a goal for the human kind. This study takes the current technical development of green energy saving product- LED light bulb, and environmental friendly material- TiO2 based air cleaner as an example to perform patent analysis. As for energy saving products, we retrieve LED bulb patent data from the USPTO patent database. United State has highest performance among all countries. The result of USPC (United States Patent Classification) technical field analysis shows that patent of green energy saving LED light bulbs primarily concentrated in technical field of D26/2, 362/249, n, and 313/46. As for environmental friendly material, this study adopts air cleaner with core technology structure of TiO2 photocatalyst materials as example to explore the technical development of TiO2 photocatalyst. Science, technology, and practical application of benchmarking company products were analyzed to explore technical roadmap of future TiO2 air cleaner development. From the comparison table of USPC patent quantity in the second section, the primary technology clusters on 422/122, and 422/186.3. The results of study show that the traditional filter are organic materials, and the reaction of UV and TiO2 photolysis will cause material aging and decomposition, so it cannot be used in the long-term. These are the biggest problems when applying photo catalyst onto the air cleaner filter. We demonstrate the development trend and operation of LED light bulbs and TiO2 air cleaner from different aspects to show that the technology gap is an important reference for other relevant companies that plan to develop new technologies and increase their competitiveness in the future. | en_US |
