Lamp Base Guide Rail Mechanism for Carrier Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lamp bases require material bonding between the light source carrier and driver, making it economically inefficient to replace a defective light source carrier.
Innovation Solution
A lamp base design featuring mutually-opposing guide rails for form-fitted insertion of the light source carrier, allowing for simple replacement without material bonding, along with a driver receptacle for perpendicular arrangement and contact clips for electrical connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If material bonding is used to connect light source carrier and driver, then connection strength is improved, but replacement complexity and cost increase
Solution Approach 1:
The patent divides the lamp base into separable components: a driver unit and a light source carrier unit connected via guide rails. This segmentation allows the light source carrier to be replaced independently without damaging the driver, resolving the contradiction between strong connection and easy replacement.
Solution Approach 2:
The guide rails act as an intermediary mechanism between the driver and light source carrier. They provide form-fitted guidance and positioning while enabling tool-free insertion and removal, achieving both secure connection and ease of replacement.
2Ease of repair
If form-fitted insertion is used for light source carrier, then replacement ease is improved, but connection strength decreases
Solution Approach 1:
The patent combines mechanical form-fitted insertion with additional retention mechanisms (such as clips or latches) to create a composite connection system. The form-fitted guide rails provide precise positioning and ease of insertion, while the retention mechanism ensures secure attachment, resolving the contradiction between replacement ease and connection strength.

AI summary
A lamp base includes a housing for at least partial accommodation of a carrier for a light source. Two mutually-opposing guide rails are provided in the housing for the form-fitted insertion of the carrier. The technology is particularly applicable to carriers with LEDs as light sources and addresses problems with adhesive or soldered attachment of the light source carrier.
