Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple lamp component structure with reflective layer and transmissive layer is used, then manufacturing costs and transportation costs are reduced, but light brightness and glare control may be compromised
Solution Approach 1:
The patent uses a composite structure consisting of a reflective layer and a transmissive layer with fluorescent powder particles. The reflective layer (with reflectivity >80%) bounces light to enhance brightness, while the fluorescent powder particles convert light wavelengths to produce desired colors. This composite material approach achieves good light brightness and color quality while maintaining a simple, low-cost structure that reduces manufacturing and transportation costs.
2Illumination intensity
If a complex lamp structure with multiple components is used, then light brightness and glare control can be achieved, but manufacturing costs and installation complexity increase
Solution Approach 1:
The patent merges multiple functions into a single integrated lamp component structure. The reflective layer and transmissive layer with fluorescent powder are combined into one component that simultaneously achieves light reflection, color conversion, and glare control. This eliminates the need for separate back plates, diffusion plates, and other components, thereby reducing structural complexity while maintaining good light brightness and low glare performance.
3Illumination intensity
If large-size lamps are used to achieve high brightness and low glare, then user preference increases, but transportation costs and installation costs increase
Solution Approach 1:
The patent employs flexible thin film structures for the reflective layer and transmissive layer. These flexible layers can be bent and folded during transportation, significantly reducing the space occupied by the lamp component. This allows large-size lamps with high brightness capability to be transported efficiently at lower costs, while the flexible nature also simplifies installation processes and reduces installation labor costs.
4Reliability
If professional installation is required for complex lamp structures, then proper installation can be ensured, but labor costs increase
Solution Approach 1:
The patent divides the lamp into a simple modular structure with distinct functional layers (reflective layer and transmissive layer with fluorescent powder). This segmentation creates a self-contained component unit that is easy to handle and install. The simplified structure with fewer parts and connections enables non-professionals to perform installation themselves, thereby reducing labor costs while maintaining reliable installation quality through the straightforward modular design.

Implementation Method 1
a part of the first light interacts with the fluorescent powder particles in the transmissive layer to excite the fluorescent powder particles, to produce second light of a desired color
Implementation Method 2
the reflective layer is a silver layer or a multilayer film structure, and the reflectivity of the reflective layer is greater than 80%

AI summary
Provided is a lamp component and a lamp device. The lamp component includes a reflective layer, having a first face and a second face which is opposite the first face and can be attached to a predetermined position, and a transmissive layer, provided on the first face of the reflective layer, the transmissive layer being doped with fluorescent powder particles, so when first light emitted from an external directional light source is incident on the lamp component from the transmissive layer, a part of the first light interacts with the fluorescent powder particles in the transmissive layer to excite the fluorescent powder particles, to produce second light of a desired color.
