Pull-Cord LED Lamp Layout for Easy Multi-Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED lighting lamps require users to frequently walk back and forth to switch lighting modes, which is inconvenient, and remote control solutions increase costs.
Innovation Solution
An LED lighting lamp with a strip-shaped casing featuring a pull-cord switch that controls multiple lamp groups, allowing mode switching by pulling the cord, and includes a mounting mechanism for easy installation and parallel connection of lamps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote control module is added to switch lighting modes, then ease of operation is improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts the control function from a complex remote control system and implements it through a simple pull-cord switch mechanism integrated directly into the lamp. This removes the need for remote controllers, mobile phones, or complex wireless communication modules while maintaining the ability to switch lighting modes conveniently.
Solution Approach 2:
The pull-cord switch is integrated directly into the lamp body, allowing the lamp to control its own lighting modes without requiring external control devices. The lamp serves itself by having the control mechanism built-in, eliminating the need for separate remote control systems.
2Ease of operation
If remote control module is added to switch lighting modes, then ease of operation is improved, but cost increases
Solution Approach 1:
The patent uses a simple, inexpensive pull-cord switch mechanism instead of expensive remote control modules with wireless communication capabilities. The pull-cord switch is a basic mechanical component that is much cheaper to manufacture while achieving the same functional goal of mode switching.
Solution Approach 2:
The patent removes the expensive remote control module entirely and extracts only the essential control function, implementing it through a simple pull-cord mechanism that costs significantly less to manufacture and install.
3Device complexity
If wall-mounted power switch is used to control lighting modes, then device complexity is kept simple, but ease of operation deteriorates due to frequent walking
Solution Approach 1:
The patent introduces a pull-cord switch as an intermediary control mechanism that bridges the gap between the user and the lighting system. The pull-cord is positioned within easy reach of the user, allowing mode switching without having to walk to a wall-mounted switch while maintaining mechanical simplicity.
Solution Approach 2:
The patent moves the control mechanism from the wall (horizontal distance) to the lamp itself (vertical/proximal dimension). By integrating the pull-cord switch into the lamp body or immediate vicinity, the user can control the lighting modes from their current position rather than traveling to a fixed wall location.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient mode switching without walking and reduces installation complexity and cost by using a pull-cord switch and mounting snap, enhancing user experience and efficiency.
Implementation Method 1
LEDs (Light Emitting Diodes), as a new type of lighting source
Implementation Method 2
Light emitted from the main lamp group is transmitted through the main light-transmitting area, and light emitted from the secondary lamp group is transmitted through the two secondary light-transmitting areas
Data Source
AI summary
A lamp including an elongated casing; first and second end covers located at opposite ends of the casing; a main board located in the casing; a plurality of LEDs located on the main board to define a main lamp group disposed beneath the main board and a secondary lamp group disposed above the main board; and a pull-cord switch configured to control the operating states of the main and secondary lamp groups.
