Solution Overview
Problem
The existing LED lighting systems face challenges in manufacturing complexity, material waste, and high costs due to the separate arrangement of lens units and the need for additional protective covers, which complicates the integration of LED light-emitting units on a circular or annular light source baseplate.
Innovation Solution
A lighting apparatus with an annular optical accommodation region and a driving accommodation region, where the light-emitting units are integrated on an e-shaped light source baseplate with a complementary circuitry, maximizing material utilization and eliminating the need for additional protective covers by using an optical element that accommodates the light-emitting units and driving circuitry within a closed configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple lens units are separately disposed on a light source baseplate, then each LED light-emitting unit can be individually covered, but the manufacturing process becomes complicated and time-consuming
Solution Approach 1:
The patent merges multiple separately arranged lens units into a single integrated optical element. This optical element contains multiple optical cavities that can simultaneously accommodate multiple LED light-emitting units, eliminating the need for separate lens units and reducing manufacturing complexity while maintaining quality coverage for each LED unit.
Solution Approach 2:
The integrated optical element serves multiple functions: it acts as a protective cover for the circuit board, provides optical cavities for multiple LED units, and eliminates the need for additional protective covers. This multi-functional design simplifies the overall structure and manufacturing process.
2Reliability
If a protection cover is additionally required to protect uncovered circuit portions, then circuit protection is improved, but the manufacturing process becomes more complicated
Solution Approach 1:
The optical element is designed to serve dual purposes: it provides optical cavities for LED units and simultaneously acts as a protective cover for uncovered circuit portions on the baseplate. This eliminates the need for separate protective covers and simplifies the manufacturing process.
Solution Approach 2:
The protective cover function is merged with the optical element. The optical element's structure is designed to extend and cover exposed circuit areas, combining protection and optical functions into a single component that simplifies assembly and manufacturing.
3Shape
If the light source baseplate is arranged in a circular or annular shape, then aesthetic appearance is improved, but a large amount of waste materials are generated during cutting and trimming
Solution Approach 1:
The patent segments the annular light source baseplate into a modular e-shaped configuration with multiple arms. This segmentation allows the baseplate to be cut from rectangular metal sheets with minimal waste, while the annular arrangement of LED units on the e-shaped baseplate maintains the desired aesthetic appearance.
Solution Approach 2:
The e-shaped baseplate design maintains the annular/circular aesthetic appearance through its curved arms and symmetrical structure, while being optimally cut from rectangular sheets to minimize material waste. The curved geometry is preserved for visual appeal while the overall shape is optimized for manufacturing efficiency.

Data Source
AI summary
A lighting apparatus includes a light source circuitry and an optical element. The light source circuitry has a light source baseplate, a plurality of light-emitting units arranged in an annular shape on the light source baseplate, and a driving circuitry located in an annular region surrounded by the light-emitting units on the light source baseplate. The optical element includes an annular optical accommodation region at an outer periphery and a driving accommodation region protruded from the optical accommodation region and is disposed in a region surrounded by the optical accommodation region. The optical accommodation region includes an optical accommodation groove which is facing the light-emitting units and configured to accommodate the light-emitting units. Light emitted by the light-emitting units is incident onto the optical accommodation groove and then exits upon being distributed; and the driving circuitry of the light source circuitry is correspondingly accommodated in the driving accommodation region.
