Lighting Apparatus for Pseudo Surroundings with Depth Perception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting apparatuses struggle to create a pseudo surrounding environment with depth while maintaining reduced dimensions, as they either appear close with light sources near the diffuser or require large dimensions when the light source is far apart.
Innovation Solution
A lighting apparatus comprising a case with a light emission panel and a light distribution modification panel, where the light emission panel emits dynamically changing light with specific luminance and chromaticity distributions, and the modification panel diffuses and transmits this light to create a blurred image, providing a sense of depth without the need for wide spacing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the light source is disposed closer to the light diffuser, then the device dimensions are reduced, but the sense of depth is lost because the light source appears close
Solution Approach 1:
A light distribution modification panel is introduced as an intermediary between the light emission panel and the observer. This panel modifies the light distribution to blur the image of the light source, preventing the light source from appearing close while allowing compact device dimensions. The intermediary panel effectively decouples the physical distance from the perceived distance.
Solution Approach 2:
The light distribution modification panel changes the parameters of light propagation by diffusing and blurring the light distribution. This parameter change (from sharp to blurred light distribution) creates the illusion of depth without requiring large physical spacing between components.
2Loss of information
If the light source is disposed far apart from the light diffuser, then the sense of depth is improved, but the device dimensions become large
Solution Approach 1:
The light distribution modification panel serves as a mediator that creates the visual effect of large spacing without the actual physical distance. By blurring the light source image, it simulates the depth effect of far-apart positioning while maintaining compact device dimensions.
Solution Approach 2:
The light distribution modification panel creates a blurred copy of the light emission pattern, which mimics the appearance of light from a distant source. This optical copying effect allows the device to achieve depth perception without the physical space required for actual distant positioning.
3Device complexity
If a conventional light source and diffuser configuration is used, then the device structure is simple, but it cannot produce a surrounding environment with depth perception
Solution Approach 1:
The lighting device is segmented into two functional panels: a light emission panel and a light distribution modification panel. This segmentation allows each panel to perform a specific function - one generates light while the other modifies its distribution - thereby achieving depth perception through the interaction between panels without excessive overall complexity.
Solution Approach 2:
The light distribution modification panel serves multiple functions: it diffuses light, blurs the light source image, and creates the perception of depth. This multi-functionality allows the device to achieve complex visual effects with relatively simple additional components, balancing structural simplicity with functional capability.

AI summary
A lighting apparatus includes: a case having an opening portion; a light emission panel in the case, the light emission panel having a light emission surface which emits light having a light distribution which dynamically changes; and a light distribution modification panel in the opening portion and having a distribution-modified light emission surface which modifies the light distribution of the light to emit light having a modified light distribution. The light emission panel emits, as the light having the light distribution, light having at least one of a luminance distribution and a chromaticity distribution of a first image to be presented on the light emission surface. The light distribution modification panel diffuses and transmits the light emitted from the light emission surface to emit light such that the at least one distribution of a second image to be presented on the distribution-modified light emission surface is changed to a blurred state.
