Solution Overview
Problem
Existing illumination devices lack a practical method to dynamically change the direction of light emission after installation, limiting their adaptability and functionality in various applications.
Innovation Solution
An illumination device comprising a light-emitting unit, a power-providing lower body, and a conversion unit that connects the upper and lower bodies, allowing for the rotation and adjustment of the light emission direction using assembly units and elastic members to maintain desired angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed illumination device is installed, then the installation structure is simple and stable, but the light emission direction cannot be changed after installation
Solution Approach 1:
The illumination device is divided into separate functional modules: a light source unit, a direction-changing member unit, and an installation base. This segmentation allows the direction-changing member to be independently adjusted without affecting the overall installation structure, enabling post-installation direction adjustment while maintaining structural simplicity.
Solution Approach 2:
The direction-changing member is designed with dynamic adjustment capabilities through elastic members and rotation mechanisms. This allows the light emission direction to be changed after installation by rotating or adjusting the direction-changing member, transforming a static fixed installation into a dynamically adjustable system.
2Adaptability or versatility
If the light emission direction is changed by rotating the whole structure, then the light direction can be adjusted, but the installation stability and position precision are reduced
Solution Approach 1:
The device separates the light source and direction-changing functions into independent units. The direction-changing member can be precisely positioned and adjusted without moving the entire installation structure, thereby maintaining installation position precision while enabling light direction adjustment.
Solution Approach 2:
A direction-changing member acts as an intermediary between the fixed installation base and the light source. This intermediary component absorbs the adjustment movements, allowing the light direction to be changed without displacing the installation base, thus preserving installation precision.
3Reliability
If elastic members are used to maintain desired angles, then the light emission direction can be held stable, but the device complexity increases
Solution Approach 1:
Elastic members are used to provide self-biasing and automatic return forces that maintain the direction-changing member at desired angles. The elastic members automatically counteract gravitational and operational forces, keeping the light emission direction stable without requiring complex active control systems or additional actuators.

AI summary
An illumination device includes a conversion unit that controls an emission direction of light emitted from a light-emitting unit included in the illumination device. The conversion unit includes a ball-shaped main body, and may be formed between an upper body, which includes the light-emitting unit, and a lower body. An assembly unit may be formed in the upper body to couple the conversion unit, and the light emission direction may be appropriately controlled by controlling the shape of the ball-shaped main body.
