Extendable LED Lamp Sliding Lighting Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LED lamps have a fixed structure, limiting their adjustable lighting range, which can be inconvenient for users needing to adapt to different environments or situations.
Innovation Solution
An extendable LED lamp design featuring a mounting mechanism with a wall seat, slideway, and protruding rib, allowing two first lighting units to slide and connect with a second unit, enabling adjustable lighting range through engagement with the mounting mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed structure is used for the LED lamp, then the structural simplicity is maintained, but the lighting range cannot be adjusted according to environmental requirements
Solution Approach 1:
The LED lamp is divided into multiple independent lighting units (first lighting units and second lighting unit) that can be separately positioned and adjusted. Each lighting unit contains its own LED chips and optical components, allowing them to be independently arranged along the sliding direction to achieve variable lighting ranges without redesigning the entire lamp structure.
Solution Approach 2:
The patent introduces a sliding mechanism with mounting slots and protruding ribs that enable the lighting units to move dynamically along the sliding direction. The spring component provides elastic force to maintain contact between sliding parts while allowing position adjustment, transforming the fixed structure into a dynamic, adjustable system that adapts to different lighting range requirements.
2Adaptability or versatility
If multiple lighting units are added to extend the lighting range, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent designs universal mounting structures including standardized mounting slots, protruding ribs, and spring components that serve multiple functions: positioning lighting units, enabling sliding movement, maintaining electrical connections, and providing mechanical support. This multi-functionality reduces the need for separate components for each adjustment function, thereby limiting the increase in device complexity despite adding multiple lighting units.
3Adaptability or versatility
If a sliding mechanism is introduced to allow adjustment, then the lighting range becomes variable, but the structural stability may be compromised
Solution Approach 1:
The spring component is pre-installed in the mounting mechanism to provide elastic cushioning force. This spring absorbs mechanical shocks and maintains continuous contact between the sliding lighting units and the mounting structure, preventing gaps or loose connections during adjustment. The elastic force compensates for manufacturing tolerances and wear, ensuring stable electrical and mechanical connections throughout the sliding range.

AI summary
An LED lamp includes a mounting mechanism, and an illuminating apparatus mounted on the mounting mechanism. The illuminating apparatus includes two first lighting units mounted on the bottom of the mounting mechanism respectively, and a second lighting unit mounted on the bottom of the two first lighting unit. The second lighting unit extends through the two first lighting unit and is connected with the mounting mechanism. Thus, the two first lighting units are slidable on the bottom of the mounting mechanism, such that the LED lamp is extendable to regulate the lighting range according to requirements of the practical environment or situation.
