Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting lamps emit single lamplight elements, creating a monotonous atmosphere that leads to visual aesthetic fatigue and fail to meet the increasing demand for diverse and engaging lamplight experiences.
Innovation Solution
A laser projector lamp with two independent projection modules, each forming a distinct light path, projects a cyclic rotating starry pattern and a cyclic flowing water wave or cloud pattern, utilizing a first projection module with a first laser light source, condenser cup, color disk, lens, and reflection assembly, and a second projection module with a second laser light source and spherical lens, to create multiple visual effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single projection module is used, then the device complexity is low, but the visual effects are monotonous and cause aesthetic fatigue
Solution Approach 1:
The patent divides the projection system into two independent projection modules (first projection module and second projection module), each capable of generating different visual effects (starry pattern and water wave/cloud pattern respectively). This segmentation allows each module to specialize in specific effects while maintaining overall system versatility without excessive complexity.
Solution Approach 2:
The lamp housing integrates both projection modules into a single device that can produce multiple types of visual effects (starry, water wave, cloud patterns) simultaneously or independently. This multi-functionality satisfies diverse user needs for different atmospheric effects while using a unified device structure.
2Adaptability or versatility
If multiple projection modules are integrated, then diverse visual effects are achieved, but the device complexity increases
Solution Approach 1:
The patent arranges the two projection modules in perpendicular dimensions with independent light paths. The first projection module creates a starry pattern while the second creates water wave or cloud patterns, allowing both effects to coexist without optical interference. This dimensional separation simplifies the overall optical path arrangement despite having multiple modules.
3Reliability
If independent light paths are used for each projection module, then visual effects do not interfere, but the device complexity increases
Solution Approach 1:
The optical system is segmented into two completely independent light paths: one for the starry pattern projection and another for the water wave/cloud pattern projection. Each light path has its own laser source, condenser, color disk, lens, and reflection assembly, ensuring that the projection effects do not interfere with each other while maintaining reliable independent operation.

AI summary
Disclosed is a novel laser projector lamp with multiple projection effects, which includes a housing body, a surface lid and a support. The support is arranged at a bottom of the housing body and used for supporting the housing body. The surface lid is arranged on one side of the housing body. The housing body includes a first projection module and a second projection module respectively forming a first light path and a second light path which do not interfere with each other and are perpendicular to each other. The surface lid is provided with a first projection area and a second projection area, a star point pattern formed by the first projection module is projected by the first projection area, and a water wave or cloud pattern formed by the second projection module is projected by the second projection area.
