Rotatable Vehicle LED Lamp Integrating Mounting and Heatsink
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
LED lamps in vehicles face challenges with heat dissipation and adjustability, as conventional cooling systems are bulky and prone to failure, and the directional light emission requires precise orientation, which is difficult to achieve in tight vehicle lamp housings.
Innovation Solution
The LED lamp design features a rotatable bulb body with an integrally formed metal mounting and heatsink portion, including a ring-shaped collar and surface undulations for compact heat dissipation, and adjustable fasteners for orienting the light-emitting diodes independently of the heatsink, allowing for secure placement and optimal light direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional cooling systems (cooling fans and heatsinks) are used to dissipate heat from LED circuitry, then heat dissipation capability is improved, but device size and complexity increase, making it difficult to fit within tight vehicle lamp housings
Solution Approach 1:
The mounting portion and heatsink portion are integrally formed as a single unit, combining the mounting function and heat dissipation function into one compact component. This eliminates the need for separate mounting brackets and heatsinks, significantly reducing the overall volume required while maintaining both mounting stability and heat dissipation effectiveness.
Solution Approach 2:
The integrally formed base serves multiple functions simultaneously: it provides structural support for mounting the LED bulb, acts as a heatsink for thermal management, and offers attachment points for securing the lamp assembly. This multi-functionality reduces the number of separate components needed, thereby reducing overall device volume.
2Temperature
If flexible heatsinks are used to improve heat dissipation, then heat dissipation capability is improved, but reliability decreases as metal strips become separated or detached, and installation becomes more difficult due to space requirements
Solution Approach 1:
The mounting portion and heatsink portion are integrally formed as a single rigid structure, eliminating the risk of separation or detachment between components. This integral construction ensures that the heatsink remains reliably attached to the mounting base throughout the product lifecycle, significantly improving durability and reliability.
Solution Approach 2:
The base is constructed from metal material that provides both structural strength and thermal conductivity. This composite approach combines the mechanical strength needed for reliable mounting with the thermal properties required for effective heat dissipation, creating a durable and reliable heatsink solution.
3Illumination intensity
If LEDs are fixed in a specific orientation to achieve proper light direction, then light emission quality is improved, but ease of installation and adjustment deteriorates in tight lamp housing spaces
Solution Approach 1:
The LED bulb body is segmented from the base assembly, with the bulb body capable of independent rotation within the collar. This segmentation allows the lighting portion to be independently positioned and oriented to achieve proper light direction, while the base remains fixed for stable mounting, greatly improving ease of installation and adjustment.
Solution Approach 2:
The bulb body is designed to be rotatable within the collar about the longitudinal axis, providing dynamic adjustability during installation. This rotational freedom allows installers to easily orient the LEDs at different angles to achieve optimal light patterns, and the position can be locked once the desired orientation is achieved.
