Solution Overview

Problem

Conventional LED lamps face issues with color temperature switching, either requiring manual lamp removal for dip switch adjustment or leading to accidental toggling and limited positions with wall switch solutions.

Innovation Solution

An LED lamp with multi-color temperature switching that integrates a control processor connected to both a dip switch and a wall switch, allowing for flexible color temperature adjustment by determining position information and detecting switch actions to control a dual-color light source unit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a multi-position dip switch is connected in series into an LED lamp to change color temperature by manual switching, then color temperature adjustment is achieved, but the lamp needs to be removed to toggle the switch and then installed again, resulting in poor ease of operation

Engineering Contradiction:
Improvecolor temperature switching operationVSAvoidtime for lamp removal and reinstallation
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent introduces a control processor as an intermediary between the dip switch and the LED light source. The control processor receives signals from the dip switch and processes them to control the color temperature of the LED, eliminating the need for direct manual switching on the lamp body and enabling remote operation through wall switches or mobile devices.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical dip switch connection system with an electronic control system. Instead of physically removing and reinstalling the lamp to change color temperature, the system uses electronic signal processing to achieve the same function, substituting mechanical operations with electronic control.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If a color temperature switching chip is connected in series onto an LED lamp to allow switching by repeatedly operating a wall switch, then color temperature switching is achieved, but it is easy to toggle the switch too many times or by accident to miss the desired color temperature, and more color temperature positions require more repeated toggling

Engineering Contradiction:
Improvecolor temperature switching flexibilityVSAvoidcolor temperature selection accuracy
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The control processor incorporates feedback mechanisms to track the current color temperature setting and provide visual or auditory feedback to the user. This helps users understand the current state and avoid accidental toggling, while the system can detect when the desired color temperature is reached and stop automatic switching.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary actions by pre-configuring multiple color temperature settings in the control processor. Instead of requiring users to repeatedly toggle switches to cycle through color temperatures, the system prepares multiple preset options and can directly navigate to or remember the desired setting, reducing the number of operations needed.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If more color temperature positions are added to the switching system, then color temperature adjustment range is improved, but more repeated toggling is required, while practical switchable color temperature positions are limited

Engineering Contradiction:
Improvecolor temperature rangeVSAvoidswitching control complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the color temperature control into multiple independent components: a control processor that manages the switching logic, a wall switch for user input, and the LED light source. This segmentation allows the system to handle multiple color temperature positions through intelligent control rather than requiring a complex mechanical switching structure for each position.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The control processor serves multiple functions: it processes dip switch signals, receives wall switch commands, stores color temperature settings, and controls the LED output. This multi-functionality allows a single control unit to manage multiple color temperature positions without requiring separate control mechanisms for each position, reducing overall system complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

An LED lamp with multi-color temperature switching includes a control processor, a dip switch processor, a wall switch processor and a dual-color light source unit. By connecting the dip switch processor and the wall switch processor to the control processor, respectively, the control processor adjusts a current output to the dual-color light source unit according to a dip switch signal or a wall switch. This enables the color temperature of the lamp to be directly determined by positioning a dip switch to a corresponding color temperature position, and allows the color temperature to be selected by operating a wall switch, thereby allowing for flexible switching of color temperature.
