Starry Sky Lamp Lens Magnification Reduces Dazzling Light Intensity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing starry sky projection lamps often produce overly bright and dazzling effects due to direct light intensity, which can be detrimental to viewing dynamic nebula changes over time, and have inefficient use of space with low surface area utilization.
Innovation Solution
A lamp design that incorporates a beam generator, an interference filter, and a reflecting mirror, with the light beam undergoing refraction and reflection sequences, followed by magnification through a lens, to reduce brightness and enhance image softness, along with a motor-controlled system for nebula and star movement, and an image projector for customizable images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the light beam directly passes through the rotating interference disk, then the dynamic nebula effect is produced, but the light intensity becomes too bright and dazzling
Solution Approach 1:
A reflecting mirror is introduced as an intermediary component between the interference disk and the projection path. The mirror reflects light through the interference disk multiple times, allowing the light to interact with the interference pattern repeatedly while controlling the final output intensity to avoid dazzling effects
Solution Approach 2:
The light beam undergoes continuous interaction with the interference disk through multiple reflections rather than a single pass. This continuous action allows for better distribution of light intensity and creates a more sustained, less dazzling projection effect
2Stability of the object's composition
If a lens is added to magnify the light beam, then the layering sense is enhanced, but the device complexity increases
Solution Approach 1:
The lens serves multiple functions: it magnifies the light beam to enhance layering effects, focuses light to improve brightness distribution, and helps control the projection area. By making the lens multi-functional, the added complexity is justified by multiple benefits rather than a single function

AI summary
A lamp projecting a starry sky is provided. The lamp projecting the starry sky includes at least one beam generator, a reflecting member with uneven and irregular reflecting surface, a first motor, and at least one first lens. The first motor is connected to the reflecting member through a connecting shaft, the reflecting member is driven to rotate when the first motor rotates, a light beam generated by the beam generator irradiates onto a first side of the reflecting member along an incident light path, and a light beam emitted from the reflecting member forms a moving and layering nebula projection after passing through the at least one first lens. In the lamp, after passing from the reflecting member, the light beam is magnified by the lens, so that the generated starry sky will not be too bright and dazzling, which effectively enhances the layering sense of the starry sky.
