Modular Recessed Downlight Assembly for Replaceable Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing downlights are integrated, making it necessary to replace the entire fixture when a component is damaged, leading to waste.
Innovation Solution
A recessed downlight with a modular design featuring a clamping ring, positioning latches, and positioning slots allows for easy replacement of components like the luminous body, with heat dissipation slots and a sealing plate enhancing functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If an integrated downlight design is used, then the structure is simple and easy to manufacture, but when a component is damaged the entire downlight must be replaced causing waste
Solution Approach 1:
The downlight is divided into multiple independent modules: drive module, luminous body module, light reflection cup module, and lampshade module. Each module can be independently replaced without affecting other components, eliminating the need to replace the entire downlight when a single component fails.
2Ease of repair
If a modular design with multiple components is used, then component replacement is enabled, but the device complexity increases
Solution Approach 1:
The modular components are nested within each other in a compact arrangement: the drive is mounted on the mounting plate, the luminous body is installed on the connecting plate below the drive, the light reflection cup surrounds these components, and the lampshade covers the entire assembly. This nested structure enables easy component replacement while maintaining a compact overall form factor.
3Reliability
If the light cylinder is sealed to protect components, then protection is improved, but heat dissipation becomes difficult
Solution Approach 1:
The sealing plate is designed with multiple heat dissipation slots that allow heat to escape from the enclosed light cylinder while still providing protection for the internal components. The sealing plate acts as a flexible barrier that selectively permits heat transfer while blocking dust and debris.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient modular mounting and replacement of components, reducing waste and improving heat dissipation, while maintaining brightness and functionality.
Implementation Method 1
When the positioning latches are in contact with the inner wall of the light cylinder, the two positioning latches are pressed to deform. After the positioning latches are aligned with positioning slots, the positioning latches restore original shapes and are clamped into the positioning slots
Implementation Method 2
a plurality of heat dissipation slots are provided in two sides of a top of the sealing plate in a penetrating manner

AI summary
A recessed downlight with a modular design is specifically provided, which relates to the technical field of downlights. A clamping ring, two positioning latches, and a light reflection cup are together put into an inner wall of a light cylinder. When the positioning latches are in contact with the inner wall of the light cylinder, the two positioning latches are pressed to deform. After the positioning latches are aligned with positioning slots, the positioning latches restore original shapes and are clamped into positioning slots to complete mounting of the clamping ring. During mounting of a lampshade, two positioning clamping blocks are aligned with two gaps, the lampshade is moved upwards to cause tops of the positioning clamping blocks to penetrate through the two gaps.
