Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Decorative lighting often relies on expensive, highly refractive materials for color separation, while less-refractive materials are less expensive but lack the necessary refractive capability, making them undesirable for lighting applications.
Innovation Solution
The use of a light-transmitting body with a diffusing element, including spherical or spheroidal grains with refractive material, which scatters and disperses light to enhance lighting intensity and color separation, utilizing a combination of incoherent and coherent light sources and dichroic properties to achieve improved light distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If highly refractive materials are used for color separation, then lighting performance is improved, but cost and manufacturing complexity increase
Solution Approach 1:
The patent changes the refractive index parameter of the material from high to low, using materials with refractive indices between 1.33 and 1.70 (such as water, alcohol, or air) instead of traditional high-refractive-index materials. This parameter change maintains adequate color separation performance while dramatically reducing manufacturing complexity and cost.
Solution Approach 2:
The patent employs composite structures combining low-refractive-index materials with specific geometric configurations (prisms, gratings, or diffuser elements) to achieve the desired optical performance. This composite approach allows the system to compensate for lower individual material refractivity through structural design, maintaining lighting performance without requiring expensive high-refractive-index materials.
2Illumination intensity
If highly refractive materials are used for color separation, then color separation performance is improved, but material cost increases
Solution Approach 1:
The patent fundamentally changes the material selection parameter from high-refractive-index materials to low-refractive-index materials (n=1.33-1.70), using common, inexpensive substances like water, alcohol, or air. This parameter change demonstrates that adequate color separation can be achieved with low-cost materials when combined with appropriate optical structures.
Solution Approach 2:
The patent adopts inexpensive materials that can be easily replaced or modified, such as liquid crystals, gels, or aerosols, which are far cheaper than traditional high-refractive-index optical materials. These materials provide sufficient color separation performance for decorative lighting applications without the high cost associated with premium optical materials.
3Ease of manufacture
If less-refractive materials are used, then cost is reduced, but refractive capability and lighting performance deteriorate
Solution Approach 1:
The patent creates composite optical systems where low-refractive-index materials are combined with structured elements (prisms, gratings, diffusers) to achieve the necessary light manipulation. The structural components compensate for the lower material refractivity, maintaining adequate color separation and lighting performance while using inexpensive materials.
Solution Approach 2:
The patent transitions from relying solely on material properties (refractive index) to incorporating geometric and structural dimensions (prism angles, grating periods, diffuser patterns). This dimensional approach allows the system to achieve optical performance through shape and structure rather than material composition, enabling the use of low-cost materials.

AI summary
Apparatus and methods for enhanced lighting. The apparatus may include a light-transmitting body. The apparatus may include a light projector. The projector may be configured to propagate into the light-transmitting body an incoming incoherent light. The projector may be configured to propagate into the light-transmitting body an incoming visible coherent light. Emerging coherent light within a visible wavelength rage attributable to the incoming visible coherent light may have a first intensity. The first intensity may be greater than a second intensity. The second intensity may be an intensity of any emerging coherent light that is within the wavelength range and is attributable to the incoming incoherent light. Emerging light may be light that emerges from the light-transmitting body.
