Dual-Mode Lamp Layout With Light Shielding for Night Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lamps with high brightness are not suitable as night lamps, affecting sleep and requiring additional night lamps that occupy electrical sockets and increase costs.
Innovation Solution
A lamp design with a main illumination assembly and a night lamp illumination assembly, separated by a light shielding member, allowing for independent operation and soft night lamp light emission through a shared exit port, with a night lamp support and transparent material for efficient light distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a single high brightness lamp is used for main illumination, then the illumination intensity is sufficient for overall environment lighting, but it is not suitable as a night lamp and may affect sleep
Solution Approach 1:
The lamp is divided into two independent illumination assemblies: a main illumination assembly with high brightness for overall lighting and a night lamp illumination assembly with soft, low brightness light for nighttime use. Each assembly has its own light source and optical path, allowing independent operation to satisfy different lighting needs without compromise
Solution Approach 2:
The lamp achieves multi-functionality by integrating both main illumination and night lamp functions into a single device. The housing contains separate control circuits and light sources that can be independently activated, allowing the same lamp to serve as both a primary lighting source and a gentle night light
2Adaptability or versatility
If an additional night lamp is purchased separately, then the night lamp function is achieved, but it occupies an additional electrical socket and increases cost
Solution Approach 1:
The patent merges the main illumination function and night lamp function into a single integrated lamp device. Both illumination assemblies share common components including the housing, power supply circuitry, and control system, eliminating the need for separate night lamp devices and reducing the total number of electrical sockets required
3Volume of moving object
If both main illumination assembly and night lamp illumination assembly are arranged in the same housing, then space is saved, but the two assemblies may interfere with and influence each other
Solution Approach 1:
A dedicated light shielding member is extracted and positioned between the main illumination assembly and night lamp illumination assembly. This shielding structure selectively blocks light paths to prevent the high brightness main illumination from overwhelming the soft night lamp light, while allowing each assembly to function independently without mutual interference
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 design meets different illumination needs, reduces environmental constraints for mounting, and ensures a compact, efficient, and cost-effective solution without additional sockets.
Implementation Method 1
A light shielding member capable of shielding light is arranged between the main illumination assembly and the night lamp illumination assembly
Implementation Method 2
at least a part of the night lamp support opposite to a light exit side of the night lamp body is made of a light-transparent material
