Solution Overview
Problem
Existing LED lamps have a fixed lens panel, limiting the adjustability of light distribution direction, which restricts their versatility in different applications.
Innovation Solution
An LED lamp design featuring a heat dissipation lamp holder with a mounting groove for the LED lamp panel, a power supply, and a first angle controller that allows for adjustable light emission by controlling groups of light-emitting elements through switches and toggles, enabling flexible light emitting angles without replacing the lens panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed lens panel is used in the LED lamp, then the structure is simple and reliable, but the light distribution direction cannot be adjusted according to different use places
Solution Approach 1:
The lens panel is divided into multiple independent lens units, each corresponding to a specific light emitting element. This segmentation allows individual lens units to be controlled independently through the controller, enabling adjustable light distribution directions without replacing the entire lens panel, thus resolving the contradiction between adaptability and structural simplicity
Solution Approach 2:
The patent introduces a controllable switching mechanism that dynamically selects which light emitting elements and corresponding lens units are active. The controller can switch between different light emitting elements, making the light distribution characteristic dynamic and adjustable according to different usage scenarios, while maintaining a relatively simple overall structure
2Adaptability or versatility
If the lens panel position is fixed, then the manufacturing is easy and cost is low, but the light emitting angle cannot be adjusted for different applications
Solution Approach 1:
By segmenting the lens panel into multiple independent units corresponding to different light emitting elements, the patent enables angle adjustment through electronic control rather than mechanical repositioning of the entire lens panel. This maintains ease of manufacture while achieving adaptability
Solution Approach 2:
The patent replaces the mechanical approach of physically repositioning the lens panel to adjust light emitting angles with an electronic control system. The controller electrically selects which light emitting elements are active, substituting mechanical adjustment with electronic switching to achieve the same functional goal more easily and reliably
3Adaptability or versatility
If multiple light emitting elements are controlled to emit light at different positions, then the light distribution direction can be adjusted, but the control system becomes more complex
Solution Approach 1:
The control system is segmented into multiple independent control channels, each corresponding to a specific light emitting element and lens unit pair. This segmentation allows the complex control function to be divided into simpler, manageable units that can be controlled independently, reducing the overall system complexity while maintaining high adaptability
Solution Approach 2:
The controller is designed with multi-functionality to manage different light emitting elements and lens unit combinations. A single controller unit can perform multiple control functions by switching between different light emitting elements, reducing the need for separate control mechanisms for each element and thereby simplifying the overall control system structure
