Spotlight Lamp Socket With Segmented Electrical And Mechanical Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spotlight lamp mounts are not adaptable to accommodate luminous means of different power levels without requiring replacement of the lamp mount or luminous means holder, leading to issues with contact pin alignment, force distribution, and reduced luminous efficiency.
Innovation Solution
The design incorporates socket pairs with adjustable distances and diameters, arranged symmetrically or asymmetrically to accommodate various luminous means, using clamping pieces that can rotate or translate to form different socket configurations, ensuring optimal contact and accommodating different power levels without replacing individual elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If contact pins are used exclusively for transmitting lamp current, then electrical contact reliability is improved, but the lamp cannot be securely fastened when high power lamps with large physical size are used
Solution Approach 1:
The invention divides the contact pin assembly into two separate functional components: contact pins dedicated solely for electrical current transmission, and a separate clamping mechanism with clamping jaws for mechanical fastening of the lamp base. This segmentation allows each component to perform its specific function optimally without interference from the other, resolving the contradiction between electrical reliability and mechanical fastening capability
Solution Approach 2:
The clamping jaws act as an intermediary mechanical fastening system between the lamp base and the lampholder body, transferring mechanical fastening forces away from the contact pins. This intermediary structure enables secure lamp mounting without subjecting the electrical contact pins to mechanical stress, thereby maintaining electrical contact reliability while providing adequate fastening for high power lamps
2Adaptability or versatility
If clamping jaws are made adjustable to accommodate different lamp base diameters, then adaptability to different lamp sizes is improved, but device complexity increases due to additional adjusting mechanisms
Solution Approach 1:
The clamping jaws are designed with dynamic adjustability through a latch mechanism that allows the jaws to be positioned at different opening degrees. This dynamic adjustment capability enables the clamping mechanism to adapt to various lamp base diameters while maintaining a relatively simple overall structure, as the adjustment is achieved through a straightforward latch-based positioning system rather than complex mechanisms
3Adaptability or versatility
If socket pairs are designed with adjustable distances and diameters, then versatility for different power levels is improved, but manufacturing complexity increases
Solution Approach 1:
The socket pairs are designed with universal adaptability features, where the distance and diameter dimensions are standardized to accommodate multiple power levels of lamps. This universal design approach allows the same socket pair configuration to serve various lamp types without requiring custom-manufactured sockets for each power level, thereby reducing manufacturing complexity while maintaining versatility
Solution Approach 2:
The invention accommodates different power levels by providing multiple socket pair configurations with varying distances and diameters as design parameters. Rather than making each socket individually adjustable, the system offers pre-configured socket pairs with optimized parameters for different lamp powers, simplifying manufacturing while maintaining adaptability across power levels
4Device complexity
If contact pins serve dual purposes as both electrical contacts and fastening means, then device complexity is reduced, but transfer resistance increases and contact reliability deteriorates under high forces
Solution Approach 1:
The invention segments the dual function of contact pins into separate components: dedicated contact pins for electrical current transmission and separate clamping jaws for mechanical fastening. This segmentation eliminates the conflict between electrical and mechanical functions, ensuring that contact pins maintain low transfer resistance and stable electrical contact while the clamping mechanism handles all mechanical fastening forces

AI summary
An apparatus for making electrical contact with luminous means in spotlights, which contain a glass vessel, a luminous means base and contact pins for the power supply is provided. The apparatus comprising a luminous means holder with at least two socket pairs for accommodating the contact pins of different luminous means. The socket pairs are arranged in clamping pieces, whose mutually opposite connecting faces can be removed from one another in order to accommodate the contact pins of the luminous means and can be guided towards one another in order to make electrical contact with the contact pins of the luminous means.
