Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current LED lights for nighttime use are limited to illuminating a single area or location, and they do not effectively project light beams to multiple areas, unlike projection LED or laser lights that focus on remote locations.
Innovation Solution
The use of Chip On Board (COB) LEDs in a plug-in outlet night light that emits light beams through multiple openings, lenses, or windows, allowing for near-by illumination of multiple locations, and featuring angle-adjustable housing parts for directed light emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional Dip or Chip LEDs are used, then each LED can be individually positioned, but they create bright spot points and require extensive soldering labor for multiple PCB assemblies
Solution Approach 1:
The patent merges multiple individual LED chips onto a single PCB substrate to form a COB (Chip On Board) LED assembly. This consolidation eliminates the need for extensive soldering of separate PCB assemblies while distributing light emission across multiple chips to reduce bright spot points and create more uniform illumination.
Solution Approach 2:
The COB LED assembly serves multiple functions simultaneously: it provides multi-directional light emission, reduces manufacturing complexity by consolidating multiple LEDs into one assembly, and eliminates bright spot issues through distributed emission from multiple chips within the single COB unit.
2Adaptability or versatility
If a single LED light source is used, then the device structure is simple, but it can only illuminate one area or location
Solution Approach 1:
The patent segments the light emission function by incorporating multiple COB LED assemblies, each oriented at different angles (e.g., 90-degree tilts), within a single housing. This allows the device to illuminate multiple locations simultaneously while maintaining a unified structural design.
Solution Approach 2:
The patent adds spatial dimensionality to light emission by tilting COB LED assemblies at various angles (e.g., 90 degrees) relative to each other. This multi-directional arrangement enables illumination of multiple areas from a single device without significantly increasing overall structural complexity.
3Area of stationary object
If projection optics lens is used to focus LED light beam, then remote distanced locations can be illuminated, but near-by illumination is not provided
Solution Approach 1:
The patent applies different light emission characteristics to different parts of the device by using multiple COB LED assemblies oriented at different angles. Some assemblies provide focused beams for remote illumination while others provide broader emission patterns for near-by illumination, creating localized quality variations in the illumination output.
