Solution Overview
Problem
Conventional lighting solutions, such as incandescent and fluorescent lights, are inefficient and have short lifespans, requiring frequent replacements, especially in hard-to-reach locations, while solid state light emitters offer energy efficiency and longevity but require comprehensive upgrades to existing fixtures.
Innovation Solution
A self-ballasted solid state light emitter lighting device that integrates the light engine, optics, power supply, and mechanical attachment into a single structure, allowing for easy replacement of traditional incandescent lamps in existing fixtures, reducing energy consumption and improving light distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If conventional lighting devices (incandescent/fluorescent) are used, then existing fixtures can be utilized, but energy efficiency is poor and lifespan is short
Solution Approach 1:
The patent combines the solid state light emitter, power supply (ballast), heat dissipation structure, and mounting components into a single integrated lighting device. This merging eliminates the need for separate fixture modifications when upgrading from conventional lighting, as the entire assembly replaces the traditional bulb while maintaining compatibility with existing fixtures.
Solution Approach 2:
The integrated lighting device is designed to perform multiple functions within a single structure: light emission, power conversion, heat dissipation, and mechanical mounting. This multi-functionality allows the device to replace conventional bulbs in existing fixtures without requiring additional components or complex installation procedures.
2Reliability
If solid state light emitters are integrated with power supply and optics, then energy efficiency and lifespan improve, but device complexity increases
Solution Approach 1:
The patent integrates the solid state light emitter, driver circuitry, heat sink, and mounting hardware into a single pre-assembled unit. This merging reduces reliability issues that would arise from field installation of multiple separate components, while maintaining the longevity benefits of solid state lighting technology.
3Ease of operation
If lighting devices are designed as single integrated units, then installation ease improves, but manufacturing complexity increases
Solution Approach 1:
While the final product is an integrated unit, the manufacturing process employs segmentation by producing components (light emitter module, heat sink, driver circuit) separately and then assembling them through automated processes. This approach simplifies manufacturing of individual components while achieving the installation ease of an integrated replacement bulb.
