“Allow Green To Shine” is a green energy initiative. LHK students hope to drive the existing advertising system on Kwong Fuk Road with green energy, incorporating interactive and artificial intelligence elements to optimize the advertising system for old buildings, benefiting economically, sustainably, and in conservation education. The students have installed a lightweight photovoltaic solar power system on the rooftop of the building, which can track sunlight to maximize the efficiency of solar power generation. Additionally, they have integrated a louvre design into traditional signs, allowing each sign to have the capability to generate electricity. Since the advertising system operates on an LED system, it is energy-saving and can display advertising effects as a whole during festivals, greatly enhancing the variation of advertising signs, the possibility of interaction with the audience, and the convenience of performances.
