Overview: “Grass Is the Spirit Of Earth” attached to the earth, and only those with a heart can discover their charm. Whenever night falls, the elves begin a lively gathering. This design adheres to the concept of sustainable development, aiming to achieve more grassland lighting with less energy and achieve a richer visual experience.This design revitalizes the idle grasslands at night and drives the development of tourism economy in surrounding cities and rural areas. By interacting with lasers and grasslands, this product integrates art into the existing natural environment, making the naturally occurring grasslands a part of presenting magical light and shadow effects. This lighting device is energy-saving and environmentally friendly, utilizing the existing natural environment and limited energy to present a vast visual spectacle. Opening the lid, the elf curiously rushed into the jar and flipped through it. In an instant, a spot of light surged out of the jar again, sweeping across the grass and shining on the leaves, instantly emitting a little green light. The beauty of the grassland is illuminated, revealing the vitality that was often overlooked before. The dots of light fluctuate up and down, like the grass dancing gracefully. Design purpose: This design revitalizes the idle grasslands at night and drives the development of tourism economy in surrounding cities and rural areas. By immersing people in nature with all their senses, this design aims to inspire people to think about the relationship between humans and nature, and inspire more people to pay attention to discovering the charm of nature. Design background: In the early stages of research, by consulting academic papers and books related to landscape, camping economy, rural construction, and tourism, and conducting field investigations in urban landscape areas, parks, and rural areas, we found that the utilization rate of grassland at night is low, which is a waste of land resources. At present, China is gradually developing rural areas and driving the economy of impoverished areas through tourism. This product revitalizes rural areas at night and allows people to discover the beauty of nature. During an outdoor building construction, we observed that when a laser level is illuminated on the grass, it creates a spectacular visual spectacle. A linear laser will penetrate through the grass leaves, illuminating the entire grassland, producing scattered green light dots, resembling the elves of the earth. We hope to use this stunning visual effect to design an outdoor lighting product and apply it to rural construction projects, in order to drive the tourism and economic development of impoverished areas.The core structure of this product is a glass bottle equipped with an LED screen and a laser irradiation device, which are respectively used to simulate the effect of sprites flipping in the bottle and emit laser light to illuminate the grass. The laser irradiation device is fixed on the During the design, we created product models of different sizes and screened them based on outdoor visual effects and interaction with lasers to obtain the best product size.This design implements the guiding ideology of Open the lid of the jar and the entire art installation starts to activate.
