Foldable LED Lamp Body with Rotating Heat Sinks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional high-power LED lamps with large heat sinks are inconvenient for packaging and transportation due to their fixed structure, which restricts their ability to be folded or unfolded.
Innovation Solution
The LED lamp design incorporates a lamp body with rotating second main bodies that can unfold for increased illumination and fold for compact storage, featuring elastic elements and sliding grooves for adjustable positioning, allowing the heat sinks to expand for better heat dissipation when in use and compact when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the LED lamp uses a large heat sink for high power operation, then heat dissipation performance is improved, but the lamp becomes difficult to fold and transport
Solution Approach 1:
The lamp body is divided into multiple detachable sections including a head housing, a rotating member with light sources, and a separate heat sink assembly. This segmentation allows each component to be optimized independently - the heat sink can be large for effective heat dissipation while the lamp body remains compact and foldable for easy transport.
Solution Approach 2:
The patent introduces a rotating member that can rotate relative to the head housing, allowing the lamp to dynamically adjust its configuration. The rotating member contains light sources that can be positioned at different angles, enabling the lamp to maintain effective heat dissipation orientation while adapting to different transport and usage requirements.
2Stability of the object's composition
If the LED lamp uses a fixed structure for stability, then structural integrity is improved, but packaging and transportation convenience deteriorates
Solution Approach 1:
The lamp is divided into separable components including the head housing, rotating member, and heat sink assembly. Each segment maintains its structural integrity independently, while the overall system becomes more convenient for packaging and transportation when disassembled or folded into a compact configuration.
Solution Approach 2:
The rotating member with light sources is designed to nest within or attach to the head housing, and the heat sink assembly can be separately positioned. This nested arrangement allows the components to occupy minimal space during transport while maintaining stable, functional configurations during operation.

AI summary
A LED lamp includes a lamp head and a lamp body mounted to the lamp head. The lamp body includes a first main body and two second main bodies. The first main body includes a first upper cover, a first lower cover, a first elastic element, and a second elastic element. Each of the second main bodies includes a second upper cover, a second lower cover. The first elastic element is mounted between the first upper cover and the second upper cover, and the second elastic element is mounted between the first lower cover and the second lower cover. When the LED lamp is in an open state, the second main bodies relative to the first main body are unfolded; when the LED lamp is in a closed state, the second main bodies relative to the first main body are folded.
