(3) At the policy level, my country's government attaches great importance to the development of the LED lighting industry and has introduced a series of policy measures to support the technological innovation and market expansion of the EL cold light film industry. For example, in recent years, the country has increased its financial subsidies to the semiconductor lighting industry and increased its support for high-performance EL cold light sheet research and development projects. In addition, with the improvement of environmental awareness, EL cold light sheets have been widely used in public lighting, transportation lighting and other fields due to their energy-saving and environmentally friendly characteristics. Taking urban road lighting as an example, using EL cold light sheets to replace traditional street lights can save billions of kilowatt-hours of electricity and reduce carbon emissions by millions of tons every year.
