LED Lamp Movable Lens Plate Screw Thread Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LED lamps lack the ability to adjust the distribution directions of light emission, as the lens plate is fixed, making it difficult to adapt to varying usage conditions without disassembly.
Innovation Solution
An LED lamp design featuring a heat sink with a movable member connected to a transparent plate via a rotation shaft and screw thread mechanism, allowing the plate to adjust its position relative to the LED light board, enabling flexible light distribution without disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the lens plate is fixed in the LED lamp, then the structural simplicity and ease of manufacture are improved, but the adaptability to different usage conditions deteriorates
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed lens plate into a movable one through a screw thread mechanism. The lens plate can be adjusted along the optical axis by rotating the screw thread, enabling dynamic adaptation to different usage conditions while maintaining a relatively simple overall structure. This resolves the contradiction by making the lens position adjustable without requiring complex disassembly or reconfiguration.
2Adaptability or versatility
If the lens plate is made movable to adjust light distribution directions, then the adaptability to different usage conditions is improved, but the device complexity increases
Solution Approach 1:
The patent uses a screw thread as an intermediary mechanism between the adjustment requirement and the lens plate movement. This simple mechanical intermediary enables smooth, precise adjustment of the lens plate position along the optical axis without requiring complex motors, sensors, or control systems. The screw thread converts rotational motion into linear displacement, providing an elegant solution that maintains device simplicity while achieving the desired adaptability.
3Ease of operation
If the lens plate position is adjustable without disassembly, then the ease of operation is improved, but the reliability of the sealed structure may deteriorate
Solution Approach 1:
The patent applies the nesting principle by integrating the screw thread mechanism within the existing lamp structure. The screw thread is positioned such that it can be accessed and operated from the exterior of the lamp without requiring disassembly of the main housing or sealing components. This nested arrangement allows users to adjust the lens plate position conveniently while maintaining the integrity and reliability of the lamp's sealed structure.

Function Achieved in This Case
Enables convenient adjustment of light distribution according to different usage conditions with a simple and non-disassembly operation, enhancing the adaptability and usability of the LED lamp.
Implementation Method 1
the rotation shaft defines a screw thread and the moving member defines a threaded hole, so that the rotation shaft is inserted into the moving member to drive the moving member to stretch out and draw back by engaging the screw thread with the threaded hole

AI summary
An LED lamp includes a heat sink with a first groove arranged on a front surface thereof for receiving an LED light board therein, a first transparent plate, a movable member installed on the heat sink and driving the first transparent plate to move relative to the LED light board, to adjust a distance between the LED light board and the first transparent plate. The movable member includes a rotation shaft, and a moving member connected to the rotation shaft by a transmission way, arranged on a side of the first transparent plate near the first groove and connected to the first transparent plate. The rotation shaft defines a screw thread and the moving member defines a threaded hole, so that the rotation shaft is inserted into the moving member to drive the moving member to stretch out and draw back by engaging the screw thread with the threaded hole.
