Solution Overview
Problem
There is a need for a decorative lighting device that can provide a decorative effect on the rear surface of display apparatuses, such as monitors and TVs, which are often exposed in interior spaces, and also include an adjustable stand mechanism to customize the distance between the user and the display.
Innovation Solution
A display apparatus with a decorative lighting device featuring an annular total reflection mirror, an annular half mirror, an annular light source, a pattern forming member, and a pattern light source, where the pattern forming member is inclined and reflects patterns between the mirrors, and a slide clamp system to adjust the stand's position, allowing for various lighting effects and user-adjustable display positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple light sources and mirrors are arranged in the recessed portion, then decorative lighting effect is improved, but device complexity increases
Solution Approach 1:
The lighting device is segmented into multiple functional components: annular light source, pattern light source, annular total reflection mirror, annular half mirror, and pattern forming member. Each component performs a specific function, allowing the complex decorative lighting effect to be achieved through coordinated operation of simpler individual elements.
Solution Approach 2:
The components are arranged in a nested configuration within the circular recessed portion. The pattern forming member is positioned on the outer side of the annular half mirror, which itself is on the outer side of the annular total reflection mirror. The annular light source is disposed between the two mirrors. This nested arrangement optimizes space utilization and simplifies the overall structural integration.
2Illumination intensity
If the pattern forming member is inclined at an acute angle, then pattern reflection effect is improved, but manufacturing precision requirements increase
Solution Approach 1:
The pattern forming member is designed with a specific inclination angle parameter (acute angle with respect to the annular half mirror) to optimize pattern reflection. By carefully selecting and controlling this angular parameter during manufacturing, the device achieves enhanced decorative effect while maintaining feasible manufacturing tolerances.
3Adaptability or versatility
If a slide clamp mechanism is added to adjust display position, then adaptability is improved, but device complexity increases
Solution Approach 1:
The stand is designed with a slide clamp mechanism that enables dynamic adjustment of the display apparatus position. The clamp can be moved along the stand column to different heights and locked in place, transforming a static support structure into a dynamically adjustable one, thereby improving adaptability to different user needs and display configurations.

AI summary
A display apparatus includes a display panel supported within a case having a rear surface including a circular recessed portion. An annular total reflection mirror and an annular half mirror are disposed in the circular recessed portion with an annular light source provided therebetween. A pattern forming member is disposed on an outer side of the annular half mirror and is configured to be reflected by the annular total reflection mirror. A pattern light source is configured to supply light to the pattern forming member so that the pattern is reflected on the annular total reflection mirror. When the annular light source and the pattern light source are turned on, the pattern of the pattern forming member is reflected between the annular total reflection mirror and the annular half mirror.
