Luminaire Insert Plate for LED Heat Dissipation and Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outdoor LED lights face challenges in heat dissipation and limited flexibility in LED module installation, which affects light distribution and service life, due to conventional screwing methods that restrict positioning and cooling capacity.
Innovation Solution
The use of clamping wedges as clamping means allows for easier replacement and adjustment of LED modules, with an insert plate acting as a heat transfer element, enabling the entire luminaire housing to function as a heat sink and allowing for various LED module patterns, while providing direct access for installation and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If LED modules are screwed into the housing with fixed screwing points, then the LED modules are securely fastened, but the installation position is limited and flexibility to use different LED modules is restricted
Solution Approach 1:
The insert plate with multiple threaded holes serves multiple functions: it provides secure fastening of LED modules through screw connections, enables flexible positioning of different LED module types, and allows for both installation and maintenance operations. The threaded holes at different locations on the insert plate accommodate various LED module hole patterns, making the system universal and adaptable to different module configurations.
2Illumination intensity
If LEDs are arranged on a carrier extending horizontally in front of the reflector, then light distribution is improved, but heat dissipation becomes difficult
Solution Approach 1:
The insert plate acts as an intermediary thermal management component between the LED modules and the luminaire housing. It provides a dedicated thermal path through its thickness to conduct heat away from the LEDs to the housing, while still allowing the LEDs to be positioned horizontally in front of the reflector for optimal light distribution. The insert plate mediates between the lighting requirement and the thermal management requirement.
3Strength
If screws are used to fasten LED modules, then the modules are securely mounted, but electrically insulating components limit the fastening forces and worsen heat transfer
Solution Approach 1:
The screw fastening operation is extracted from the main luminaire housing and transferred to the insert plate. This allows the use of conductive fasteners that can be tightly torqued for secure mounting without compromising the electrical insulation of the main housing or interfering with the thermal path to the housing. The insert plate separates the mechanical fastening function from the electrical insulation and thermal conduction functions.
