Solution Overview
Problem
Existing light emitting devices lack the capability to indicate lights emitted from multiple elements in a superimposed manner or exclusively indicate light from one element, limiting variation in indication.
Innovation Solution
An indicating device with a partition wall separating light emitting elements, where one region is irradiated with light from two elements in a superimposed manner and another region is irradiated only with light from a single element, using a light-shielding part to enhance clarity and visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a frame body defines each region of the wavelength conversion layer that is irradiated with light emitted from a corresponding one of the plurality of light emitting elements, then the light emission color of each light emitting element can be clearly indicated, but the capability to indicate lights emitted from multiple elements in a superimposed manner or exclusively indicate light from one element is lost
Solution Approach 1:
The indicating part is divided into multiple regions by partition walls, with each region corresponding to a specific light emitting element. This segmentation allows different regions to display different light emission colors simultaneously, enabling both exclusive indication and superimposed indication capabilities.
Solution Approach 2:
Different regions of the indicating part are assigned different optical properties through selective light shielding. Some regions allow light from multiple elements to reach (superimposed indication), while other regions are shielded from specific elements' light (exclusive indication), creating local quality variations that enable diverse indication modes.
2Measurement precision
If the partition wall is positioned close to the first light emitting element to define the first region, then the light emission color of the first light emitting element can be clearly indicated in the first region, but the light intensity from the second light emitting element in the first region may be insufficient
Solution Approach 1:
A light-shielding part is introduced as an intermediary element to selectively block light from the first light emitting element in specific areas. This allows the partition wall to be positioned close to the first light emitting element for clear color indication, while the light-shielding part controls which regions receive light from the second element, maintaining sufficient light intensity where needed.
3Device complexity
If the indicating part is uniformly irradiated with light from all light emitting elements, then the structure is simple, but the capability to provide varied indication patterns and enhance user recognition of operation parts is reduced
Solution Approach 1:
The indicating part is segmented into multiple regions by partition walls, with each region associated with specific light emitting elements. This segmentation enables different indication patterns (exclusive indication, superimposed indication, sequential indication) without requiring complex additional structures, maintaining simplicity while enhancing user recognition.
Solution Approach 2:
The light-shielding part can be positioned differently to dynamically change which regions are illuminated by which light emitting elements. This dynamic control allows the system to switch between different indication modes (such as highlighting operation parts vs. showing operating modes) without physical reconfiguration, enhancing ease of operation.

AI summary
This indicating device (20) includes a first light emitting element (31), a second light emitting element (32) capable of emitting light different in light emission color from light emitted from the first light emitting element (31), an indicating part (51) that is translucent and is irradiated with the light emitted from the first light emitting element (31) and the light emitted from the second light emitting element (32), and a partition wall (42) provided between the first light emitting element (31) and the second light emitting element (32) to define a first region (52) of the indicating part (51). A first distance between the partition wall (42) and the first light emitting element (31) is shorter than a second distance between the partition wall (42) and the second light emitting element (32). The indicating part (51) and partition wall (42) are arranged at a distance from each other.
