Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing phototherapy equipment fails to accurately adjust light irradiation based on the position of affected parts and the progression of symptoms over time.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional phototherapy equipment uses a single light emitter, then the device structure is simple, but it cannot differentiate emission wavelengths and cumulative light quantities for different affected parts and symptom stages
Solution Approach 1:
The light-emitting part is segmented into multiple light emitters with different emission wavelengths (first light emitters and second light emitters). Each light emitter can be independently controlled to emit light, allowing the device to differentiate emission wavelengths and cumulative light quantities according to different affected parts and symptom stages, thereby resolving the contradiction between adaptability and device complexity
Solution Approach 2:
The control part dynamically switches between different operation modes (first mode, second mode, third mode) based on treatment requirements. This dynamic control enables the device to adapt to different affected parts and symptom progression stages while maintaining a relatively simple overall structure, balancing adaptability and device complexity
2Measurement precision
If phototherapy equipment uses multiple light emitters with different wavelengths, then it can accurately irradiate light according to affected parts and symptoms, but the control system becomes more complex
Solution Approach 1:
The control part changes operational parameters by switching between different modes (first mode with first light emitters, second mode with second light emitters, third mode with both). This parameter-based control approach enables accurate light irradiation according to different affected parts and symptoms while keeping the control system relatively simple through mode-based management rather than complex individual control of each light emitter

AI summary
An object of the present invention is to provide a light irradiation device that is capable of accurately irradiating light according to affected parts and their symptoms. A light irradiation device 1 irradiating light to an affected part, includes a main body 2 including a substrate 5, and a light-emitting part 7 that is disposed on at least one surface 5a of the substrate 5 and includes a plurality of light emitters 6 with different emission wavelengths, and a controller 3 equipped with a control part 8 that controls light emission from the light-emitting part 7. The light-emitting part 7 at least includes the first light emitters 6a emitting light with a wavelength in the first band and the second light emitters 6b emitting light with a wavelength in the second band, different from the first band. The control part 8 executes an operation by switching at least between the first mode in which the first light emitters 6a are made to emit, the second mode in which the second light emitters 6b are made to emit, and the third mode in which the first light emitters 6a and the second light emitters 6b are made to emit.
