Projection Lamp Modules for Dynamic Nebula and Star Effects
Solution Overview
Problem
Current lighting lamps offer only monotonous lighting and fail to create diverse and aesthetically pleasing atmospheres, leading to visual fatigue as consumers seek more engaging lighting experiences.
Innovation Solution
A projection lamp with three distinct modules: one for creating the effect of nebulae and iridescent clouds, another for twinkling stars, and a third for various nebulae or cloud shapes, utilizing rotating motors, LEDs, lasers, diffractive optical elements, and concave-convex surfaces to achieve dynamic lighting effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single emitted light element is used for lighting, then the lighting function is simple and reliable, but the lighting atmosphere becomes monotonous and causes visual aesthetic fatigue
Solution Approach 1:
The lighting device is divided into three independent projection modules, each responsible for a specific lighting effect (nebulae and iridescent clouds, twinkling stars, and different shapes of nebulae or iridescent clouds). This segmentation allows each module to be optimized for its specific function while maintaining overall system versatility.
Solution Approach 2:
The projection lamp integrates multiple projection modules that can work independently or in combination, enabling the device to provide diverse lighting atmospheres including nebulae effects, star effects, and combined effects, thus achieving multi-functionality in a single lighting device.
2Adaptability or versatility
If multiple projection modules are added to create diverse lighting effects, then the lighting atmosphere becomes diverse and engaging, but the device structure becomes more complex
Solution Approach 1:
Multiple projection modules are merged into a single integrated housing structure, sharing common components such as the power supply unit, control circuit board, and housing. This merging approach reduces overall device complexity while maintaining the diversity of lighting effects through modular design.
Solution Approach 2:
The integrated design allows the lighting device to perform multiple functions through different module combinations, providing nebulae effects, star effects, and combined effects in a single device, achieving versatility without proportionally increasing complexity.
3Adaptability or versatility
If independent projection modules are used for different effects, then customizable lighting effects can be displayed independently or combined, but the manufacturing process becomes more difficult
Solution Approach 1:
The device is segmented into standardized projection modules that can be manufactured independently and then assembled into the final product. This segmentation facilitates modular manufacturing, where each module can be produced using optimized processes for its specific function.
Solution Approach 2:
The modular design with standardized interfaces and shared components enables flexible assembly configurations, allowing manufacturers to produce different versions by combining modules in various arrangements while maintaining ease of assembly through universal mounting structures.
