Ceiling Lamp Night Light Shielding Glare
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ceiling lamps struggle to provide adjustable light intensity, leading to uneven lighting that affects visual perception, and they are often too bright for scenarios requiring weaker light, such as night lighting.
Innovation Solution
A ceiling lamp design featuring a chassis, diffusion cover, main light source, light shield, and a separate night lamp light source, where the main light source emits strong light for high-intensity scenarios and the night lamp light source emits weak light, with the light shield directing the night lamp light outward to reduce downward radiation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the number of light emitting beads is reduced to switch brightness, then the light intensity is lowered, but the lighting becomes uneven and visual perception is affected
Solution Approach 1:
The patent divides the lighting system into two separate modules: a main light source with multiple light emitting beads for primary illumination, and a separate night lamp light source with fewer beads for low-intensity lighting. This segmentation allows each module to operate independently with optimized bead arrangements, avoiding the uniformity problems that would result from simply reducing beads in a single system.
Solution Approach 2:
The patent applies different lighting characteristics to different functional zones: the main light source provides high-intensity illumination for daytime or task lighting, while the night lamp light source provides low-intensity, gentle lighting for nighttime use. Each zone has optimized light emitting bead configuration suited to its specific lighting requirements, rather than using a uniform configuration for all scenarios.
2Illumination intensity
If the light emitting intensity is increased to meet daily lighting needs, then sufficient illumination is provided, but the ceiling lamp becomes dazzling and cannot serve as a night light
Solution Approach 1:
The patent creates a multi-functional ceiling lamp that can serve both as a main lighting fixture for daytime/task lighting and as a night light. The main light source provides high-intensity illumination when needed, while the separate night lamp light source provides low-intensity gentle lighting for nighttime scenarios, allowing a single device to adapt to multiple application requirements without compromise.
Solution Approach 2:
By separating the lighting functions into distinct modules (main light source and night lamp light source), the patent enables independent control of each function. This allows the system to provide either high-intensity main lighting or low-intensity night lighting as needed, rather than being constrained to a single light intensity level.
3Illumination intensity
If the night lamp light source is disposed on the outer wall surface of the diffusion cover, then weak light can be emitted for night scenarios, but light may propagate downward causing glare
Solution Approach 1:
The patent extracts the night lamp light source from the internal accommodating cavity and positions it on the outer wall surface of the diffusion cover. This extraction allows the night lamp to emit light directly outward through the diffusion cover material, which diffuses the light in outward directions while the light shield blocks downward propagation, separating the desired outward diffusion function from the harmful downward light propagation.
Solution Approach 2:
The light shield acts as an intermediary element that selectively blocks downward light propagation from the night lamp light source while allowing outward light diffusion through the diffusion cover. This intermediary component resolves the contradiction by permitting the beneficial outward light emission while preventing the harmful downward light propagation that would cause glare.
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 effectively meets high light intensity requirements with the main light source while providing a gentle night light option, reducing glare and improving visual comfort by diffusing the night lamp light outward.
Implementation Method 1
The light shield is used for limiting an irradiation direction of the night lamp light source and ensuring that rays emitted from the night lamp light source are diffused to an outer side of the ceiling lamp
Implementation Method 2
the diffusion cover is disposed on the chassis, and the chassis and the diffusion cover are enclosed to form an accommodating cavity
