Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LARP lighting apparatuses have complex and high-volume structures, leading to increased production costs and reduced compactness and robustness.
Innovation Solution
A lighting apparatus with a phosphor body and dichroic mirrors, where one dichroic mirror region deflects primary light onto the phosphor body for wavelength conversion, and another region deflects primary light circumventing the phosphor body, eliminating the need for a deflection mirror system and additional light sources, resulting in a simpler, more compact, and robust structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a deflection mirror system and additional light sources are used to provide primary light component, then the lighting apparatus can achieve complete primary light utilization, but the structure becomes complicated and high-volume
Solution Approach 1:
The patent combines the functions of the deflection mirror system and additional light sources into the dichroic mirror itself. The dichroic mirror is divided into a first region that reflects primary light onto the phosphor body and a second region that allows primary light to pass through, eliminating the need for separate deflection mirrors and additional light sources while maintaining complete primary light utilization
Solution Approach 2:
The dichroic mirror performs multiple functions: it acts as a wavelength conversion interface for the phosphor body, separates primary light into reflected and transmitted components, and provides the necessary beam paths without requiring additional dedicated components. This multi-functionality reduces the overall component count and structural complexity
2Ease of manufacture
If multiple components are used for light deflection and mixing, then light distribution can be optimized, but production costs increase
Solution Approach 1:
By merging the light deflection and mixing functions into the dichroic mirror's dual-region structure, the patent reduces the number of procurement items while maintaining optimized light distribution. The first region directs light for wavelength conversion and the second region provides direct primary light transmission, achieving homogeneous intensity distribution without additional components
3Reliability
If a compact structure is achieved by reducing components, then robustness improves, but light yield may be compromised
Solution Approach 1:
The dichroic mirror exhibits local quality differences through its dual-region design: the first region is optimized for reflecting primary light onto the phosphor body to maximize wavelength conversion efficiency, while the second region is optimized for transmitting primary light directly. This localized functional differentiation ensures high light yield in both converted and direct light paths while maintaining a compact, robust structure

AI summary
A lighting apparatus includes at least one primary light source for emitting primary light, at least one phosphor body arranged at a distance from the primary light source, for converting the wavelength of primary light into secondary light, and at least one at least partly dichroic mirror, which at least partly deflects primary light radiated thereon onto at least one phosphor body and which passes secondary light radiated by the phosphor body. Used light radiated by the lighting apparatus contains the secondary light and primary light radiated by at least one primary light source, and the dichroic mirror includes at least one first and second mirror regions, in such a way that the first mirror region deflects primary light onto at least one phosphor body and passes secondary light incident from the phosphor body, and that the second mirror region deflects primary light in a manner circumventing the phosphor body.
