Solution Overview
Problem
Existing electric light bulb type light source apparatuses face issues with heat from the light source unit affecting the speaker, leading to deterioration of speaker function and subpar sound quality.
Innovation Solution
The apparatus separates the light source unit and speaker using a support unit, with the light source unit disposed between the speaker and the base, and incorporates a translucent cover and reflection members to enhance light distribution and reduce heat impact, while using a ring-shaped light source unit and translucent materials to improve illumination and sound quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the light source unit and speaker are disposed close to each other in the same plane, then the device complexity is reduced and manufacturing is easier, but the speaker is easily affected by heat from the light source unit leading to deterioration of speaker function
Solution Approach 1:
The support unit is divided into a first support portion and a second support portion that are spatially separated. The light source unit is mounted on the first support portion while the speaker is mounted on the second support portion, physically segmenting the heat-generating and heat-sensitive components to prevent thermal interference while maintaining integrated support.
Solution Approach 2:
The patent transitions from a planar arrangement where the light source and speaker are disposed in the same plane to a three-dimensional configuration where the light source unit is positioned above the speaker in the vertical direction. This dimensional change allows effective heat isolation while maintaining compact device structure.
2Illumination intensity
If the light source unit is disposed around the speaker along the vibration direction, then the light distribution angle is increased, but the disposition space is increased and device size is enlarged
Solution Approach 1:
The light source unit is nested around the speaker in a concentric arrangement where the ring-shaped light source unit is positioned above the speaker with its inner circumference facing the speaker. This nesting configuration allows the light source unit to be disposed around the speaker along the vibration direction, increasing light distribution angle while minimizing the overall disposition space through efficient spatial utilization.
3Reliability
If the light source unit and speaker are separated, then heat influence on the speaker is suppressed, but the device complexity increases
Solution Approach 1:
The support unit is designed as a multi-functional integrated component that simultaneously performs the functions of: (1) supporting the light source unit, (2) supporting the speaker, (3) positioning the light source unit above the speaker for heat isolation, and (4) providing structural rigidity to the entire assembly. This universal design reduces overall device complexity despite the separated arrangement of functional components.
