Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional lighting systems are used to emit surface light, then illuminance is achieved in a limited place, but the ability to create three-dimensional effects is lost
Solution Approach 1:
The patent introduces a half-mirror member that creates virtual images by reflecting light, adding a dimensional aspect to the lighting. This allows the system to produce both direct surface light and reflected virtual light, creating three-dimensional visual effects while maintaining the original surface illumination function.
Solution Approach 2:
The half-mirror member acts as an intermediary element between the light source and the observer. It partially transmits light to maintain surface illumination while partially reflecting light to create virtual images, thereby enabling three-dimensional effects without compromising the primary lighting function.
2Adaptability or versatility
If multiple light emitting units are used to achieve three-dimensional effects, then design flexibility increases, but device complexity and cost increase
Solution Approach 1:
Instead of using multiple physical light emitting units, the patent uses a half-mirror member to create virtual copies or images of the light source. This single physical light source generates multiple visual light sources through reflection, achieving design flexibility without increasing the actual number of light emitting units.
Solution Approach 2:
The half-mirror member serves multiple functions simultaneously: it transmits light to maintain surface illumination, reflects light to create virtual images for three-dimensional effects, and does so using a single light source. This multi-functionality reduces the need for additional light emitting units while maintaining design flexibility.
3Loss of energy
If a resin layer is used to guide light for three-dimensional effects, then optical efficiency increases and number of light sources decreases, but manufacturing precision requirements increase
Solution Approach 1:
The patent employs a resin layer as a flexible light guidance structure that can be molded into various shapes to control light propagation. This thin film approach enables efficient light guidance for creating three-dimensional effects while being more manufacturable than rigid precision optical components.
Solution Approach 2:
The resin layer's optical parameters (refractive index, thickness, shape) are optimized to achieve efficient light guidance. By adjusting these parameters during manufacturing, the system achieves high optical efficiency without requiring extremely tight manufacturing tolerances, balancing performance with manufacturability.

AI summary
Embodiments of the present invention relate to a lighting apparatus capable of providing three-dimensional effects at the same time as the surface emission of light sources by using a half-mirror member for reflecting and transmitting parts of light. In particular, by adopting the half-mirror member for transmitting a part of and reflecting another part of light emitted from a surface-emitting light source module, the present invention allows the implementation of a mirror-like image when the light is off, and allows the implementation of a light image providing various three-dimensional effects when the light is on.
