Solution Overview
Problem
Current inverted-Fuji lighting devices suffer from partial light loss due to their optical structure, reducing luminous efficacy, and have complex installation processes that increase labor costs.
Innovation Solution
A high luminous-efficacy linear lighting device design featuring a tubular light cover with a curved light-emitting portion and a light-shielding portion, an all-plastic structure, a built-in power module, U-shaped clips for single-side fastening, and safety ropes for easy installation, along with a support plate made of high thermal conductivity materials for heat dissipation and structural support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the optical structure of inverted-Fuji lighting devices is used, then uniform light distribution is achieved, but partial light loss occurs reducing luminous efficacy
Solution Approach 1:
The lighting device is divided into a light-emitting portion and a light-shielding portion within the tubular light cover. This segmentation allows the light-emitting portion to be optimized for uniform light distribution while the light-shielding portion prevents light loss by blocking light paths that would otherwise escape or reflect back onto the light source board.
Solution Approach 2:
Different portions of the tubular light cover have different optical properties: the light-emitting portion is designed to emit and distribute light uniformly, while the light-shielding portion is designed to block and redirect light. This local differentiation of optical quality resolves the contradiction by allowing each region to perform its specific function optimally.
2Stability of the object's composition
If the traditional installation process for inverted-Fuji lighting devices is used, then proper positioning is achieved, but complex installation procedures increase labor costs
Solution Approach 1:
The tubular light cover is pre-assembled with the light source board, support plate, and internal components before installation. This preliminary assembly means that during installation, the entire lighting device can be mounted as a single unit, significantly reducing on-site installation complexity and labor requirements while maintaining proper positioning.
Solution Approach 2:
Multiple components (light source board, support plate, power module, tubular light cover) are combined into a single integrated assembly. This merging reduces the number of separate installation steps and simplifies the overall installation process while ensuring proper positioning and stability of all components.

AI summary
A high luminous-efficacy linear lighting device includes a tubular light cover, a support plate and a light source board. The tubular light cover has a light-emitting portion and a light-shielding portion. The light-emitting surface of the light-emitting portion is a curved surface. The bottom of the light-emitting portion has a lower opening. The top of the light-shielding portion has an upper opening. The bottom of the light-emitting portion is connected to the top of the light-shielding portion. The width of the bottom of the light-emitting portion is greater than the width of the top of the light-shielding portion. The support plate is disposed within the light-shielding portion and adjacent to the upper opening. The light source board is disposed on one side of the support plate and faces the light-emitting portion.
