Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lamps have complex production processes and high space requirements due to the need to arrange electrical components on the side of the printed circuit board facing the base section, which can obstruct light emission and increase production costs.
Innovation Solution
A lamp design where the printed circuit board is fixed inside a U-shaped carrier with light sources facing towards the inside, allowing electrical components to be placed on the opposite side, and an insulating layer prevents electrical contact while optimizing light emission through feedthroughs and optically effective sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If electrical components are arranged on the side of the circuit board facing the base section, then the luminaire can be assembled with all necessary components, but the production process becomes complex and space requirements increase
Solution Approach 1:
The patent inverts the conventional arrangement by placing the circuit board with its illuminating side facing towards the inside of the carrier rather than away from it. This inversion allows electrical components to be arranged on the opposite side of the circuit board, eliminating the need for complex base structures while simplifying the production process and reducing space requirements
2Illumination intensity
If electrical components are arranged on the side of the circuit board facing the base section, then the luminaire can be assembled with all necessary components, but light emission is obstructed and requires additional space
Solution Approach 1:
By inverting the circuit board orientation so the illuminating side faces inward toward the carrier, the patent enables light to emit directly outward through the carrier wall without obstruction from electrical components. This eliminates the need for additional space to accommodate both light sources and electrical components separately
3Ease of manufacture
If the circuit board is placed on the base section with light sources facing away, then light can emit from the open side of the U-shaped carrier, but additional components obstruct the light path and increase manufacturing complexity
Solution Approach 1:
The patent applies inversion by positioning the circuit board with its illuminating side facing toward the inside of the carrier, which reverses the conventional arrangement. This allows electrical components to be placed on the opposite side of the circuit board, eliminating the need for complex base structures and simplifying manufacturing while maintaining proper light emission
