Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current LED lamps lack the ability to dynamically change color patterns and mix different light sources effectively, limiting their aesthetic and functional versatility.
Innovation Solution
A lamp design featuring a source plate with multiple light sources, including LEDs, where one set generates white light and another set generates colored light, oriented at an acute angle, with a diffuser plate and driver insulator to create distinct light regions, and a switch mechanism for power control, allowing for various color combinations and patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple light sources with different colors are used, then aesthetic appeal and color versatility are improved, but device complexity increases
Solution Approach 1:
The patent combines multiple light sources (white light LEDs and colored LEDs) into a single lamp housing with a common power supply and control circuitry. The white light sources and colored light sources are integrated on the same source plate, sharing structural support and electrical connections, which reduces overall system complexity compared to separate lighting systems.
Solution Approach 2:
The lamp is designed to perform multiple functions simultaneously: it can produce white light for general illumination, colored light for aesthetic effects, and mixed colors for dynamic patterns. The single lamp housing and power system support multiple operational modes, making the device universally applicable for both functional and decorative lighting needs.
2Adaptability or versatility
If light sources are oriented at acute angle offset, then light mixing and color patterns are improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent applies different orientation angles to different light sources based on their specific functions. White light sources are oriented at one angle optimized for general illumination, while colored light sources are oriented at acute angle offsets optimized for creating specific color patterns and effects. This localized optimization allows each light source to perform its specific function effectively.
Solution Approach 2:
The lamp incorporates a controller that can dynamically adjust which light sources are activated and at what intensity levels. This dynamic control allows the system to compensate for fixed orientation angles by varying the activation patterns, thereby achieving desired light mixing and color patterns without requiring precise mechanical adjustment of each light source.
3Illumination intensity
If diffuser plate and driver insulator are used to define light box region, then light dispersion and aesthetic appeal are improved, but device complexity increases
Solution Approach 1:
The driver insulator serves multiple functions: it provides electrical insulation for the driver circuitry, acts as a structural support element, and contributes to defining the light box region that guides light dispersion. The diffuser plate simultaneously diffuses light for even distribution and helps define the light box geometry. This multi-functionality reduces the need for additional separate components.
Solution Approach 2:
The patent merges the driver insulator with the structural framework that defines the light box region. Rather than using a separate insulator and separate structural elements, the insulator itself forms part of the light box boundaries, combining insulation and structural functions into a single integrated component.

Function Achieved in This Case
Enables dynamic color changes and mixing of light sources, enhancing aesthetic appeal and user customization while maintaining energy efficiency and long lifespan.
Implementation Method 1
a lens that encapsulates the first set of the plurality of light sources and redirects the light generated by the first set of the plurality of light sources
Implementation Method 2
The driver insulator acts as a reflector (that is, a surface of the driver insulator is diffusively reflective)
Implementation Method 3
the diffuser plate acts as a diffuser, such that light generated by the second set of the plurality of light sources is dispersed from the light box region through the diffuser plate

AI summary
A lamp (100) including a two-sided source plate (212), a plurality of light sources (214), a lens (218), a diffuser plate (206), and a driver insulator (208) is disclosed. One set (280) of the light sources (214) generates white light and is attached to one side (270) of the source plate. Another set (282) of the light sources (214) generates colored light and is attached to the source plate's other side (272). The lens (218) encapsulates the white light-generating set (280), and redirects that white light. The driver insulator (208) and the diffuser plate (206) are each in contact with the source plate's other side (272). The driver insulator (208), diffuser plate (206), and that side (272) of the source plate define a light box region (240) that contains the colored light-generating set (282) of light sources (214). The driver insulator (208) acts as a reflector, and the diffuser plate (206) acts as a diffuser, such that colored light is dispersed from the light box region (240) through the diffuser plate (206).
