Dual Light Source Lamp with Independent Control Circuit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional household lamps often neglect user comfort and environmental lighting effects, resulting in inadequate lighting experiences.
Innovation Solution
A household lighting lamp design featuring a main and secondary light-emitting component, both connected to a control circuit, allowing for adjustable lighting modes. The main light source provides direct, high-intensity lighting, while the secondary light source emits light from the sides or rear, reducing intensity and creating a softer, more uniform ambient light.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single light source is used to provide illumination, then the device structure is simple, but the lighting comfort and environmental effect are poor
Solution Approach 1:
The patent divides the light-emitting function into two independent components: a main light source for direct illumination and a secondary light source for ambient illumination. This segmentation allows each light source to be optimized for its specific function, improving overall lighting comfort while maintaining manageable structural complexity through modular design
Solution Approach 2:
The patent applies different lighting characteristics to different spatial zones: the main light source provides high-intensity direct lighting for task areas, while the secondary light source provides low-intensity diffuse lighting for ambient illumination. This local differentiation of lighting quality enhances comfort and functionality
2Illumination intensity
If direct high-intensity lighting is provided, then the illumination intensity is sufficient, but the light comfort and environmental effect deteriorate
Solution Approach 1:
The patent segments the lighting function into two independent light sources: the main light source delivers high-intensity direct illumination for task requirements, while the secondary light source provides low-intensity ambient lighting that enhances comfort. This segmentation resolves the contradiction by allowing high intensity where needed without compromising comfort
Solution Approach 2:
The secondary light source acts as an intermediary that provides supplementary ambient illumination, softening the harsh effects of direct lighting. This intermediary light source creates a more balanced lighting environment that maintains sufficient illumination intensity while improving overall comfort
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for independent control of direct and ambient lighting, meeting diverse user needs and enhancing comfort by providing high-intensity direct lighting and soft, diffused ambient lighting.
Implementation Method 1
the main light guiding element is located in front of the lamp holder, the main light source forms a light-guiding connection with the main light guiding element
Implementation Method 2
the secondary light guiding element is provided in front of or at a side of the lamp holder, the secondary light source forms a light-guiding connection with the secondary light guiding element
