LED Lamp Angle Controller for Adjustable Light Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LED lamps have fixed lens positions, single output power settings, and limited control modes, which restrict their adaptability to different lighting requirements and lead to inefficient energy use.
Innovation Solution
The LED lamp features a lamp holder with a mounting groove, an LED lamp panel with uniformly arranged light-emitting elements, a driving power supply, a light-transmitting plate, and an angle controller. The angle controller, comprising a switch base, electronic switch, and handle, allows for adjustable light emission based on different states, enabling flexible control of light angle, color temperature, and power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the lens plate position is fixed in conventional LED lamps, then the structure is simple and easy to manufacture, but the light distribution direction cannot be adjusted and adaptability to different lighting requirements is poor
Solution Approach 1:
The light-emitting elements are divided into multiple groups arranged in different sectors (first sector, second sector, third sector, fourth sector) around the light-transmitting plate. Each group can be independently controlled to emit light, allowing the light distribution direction to be adjusted by selecting which groups are activated, thereby achieving adaptability without complex mechanical lens adjustment mechanisms.
Solution Approach 2:
The angle controller acts as an intermediary device that selectively controls the activation of different light-emitting element groups based on the required lighting direction. By using this control mechanism, the patent achieves flexible light distribution adjustment without requiring physical movement of the lens plate or complex optical switching systems.
2Loss of energy
If the LED lamp has a single output power setting, then the device structure is simple, but electric resources are wasted in places with small lighting area or low lighting brightness requirements
Solution Approach 1:
Instead of activating all light-emitting elements simultaneously, the angle controller enables selective activation of only the necessary groups based on the actual lighting requirements. For example, only one or two adjacent groups may be activated for small lighting areas, while more groups are activated for larger areas, thereby reducing energy consumption without requiring a complex dimming system.
Solution Approach 2:
The light-emitting elements are segmented into multiple independently controllable groups arranged in sectors. This segmentation allows the system to activate only the required portion of the total light output, matching the energy consumption to the actual lighting needs and avoiding waste in applications with small lighting areas or low brightness requirements.
3Adaptability or versatility
If a single control mode is provided in LED lamps, then the control system is simple, but it cannot flexibly meet diverse market demands
Solution Approach 1:
The angle controller provides dynamic control capabilities by enabling multiple control modes (first control mode, second control mode, third control mode) that can be selected based on different lighting scenarios. The system can dynamically adjust which light-emitting element groups are activated and at what intensity, providing flexibility to meet diverse market demands without requiring multiple separate control systems.
Solution Approach 2:
The angle controller serves multiple functions: it can control light distribution direction by selecting which groups are activated, adjust output power by controlling the intensity of activated groups, and provide different control modes for various lighting scenarios. This multi-functionality is achieved through a single integrated control device, avoiding the need for multiple separate control systems.
