[0002] At present, with the continuous improvement of people's material and cultural life, night scene lighting has become an important part of the demand for a better life. The role of night scene economics in stimulating domestic demand is becoming more and more obvious. People's requirements for light are no longer limited to lighting, but more focused on its decorative and entertaining nature. They need more elements from nature and more psychological hints. Water is an element that is widely loved by the people. Water is also an important part of Chinese philosophy. When water drops into the calm lake, the dynamic ripples are a common ups and downs phenomenon, accompanied by corresponding light reflection and refraction, which has a relatively ethereal beauty. The existing technology commonly used to achieve dynamic ripples is digital projectors, which rely on regular imaging optical paths such as linear imaging lamps based on single-axis plano-convex mirrors, but the machines are often too large and expensive. Based on this, some manufacturers' physical projection lamps have defects such as insufficient brightness and non-concentric apertures, which seriously affect the product experience and limit the usage scenarios.

[0003] Therefore, how to provide a dynamic ripple effect lamp that can achieve physical projection, has rich projection effects, and can be used in different scenes is a problem that technical personnel in this field urgently need to solve. Utility Model Content
