Solution Overview

Problem

Conventional lamps fail to adapt light color temperature effectively for varying environmental conditions, such as rain or fog, leading to inadequate illumination and safety issues.

Innovation Solution

A lamp color temperature change structure comprising a lamp holder, a light source, a lift unit, and a colored lens, where the colored lens is movable to adjust the light's color temperature by positioning itself either in front of or away from the light source, allowing for desired color temperature changes based on environmental conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If the color temperature is increased to over 4200K to provide brilliant light, then the illumination intensity is improved, but the penetration ability deteriorates

Engineering Contradiction:
Improveillumination intensityVSAvoidpenetration ability
Core Design Contradiction:
Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The patent applies a movable colored lens that can dynamically adjust its position between a first position (away from the light source) and a second position (in front of the light source). This dynamic positioning allows the system to switch between high illumination intensity mode (colored lens away) and good penetration mode (colored lens in front), resolving the contradiction between these two opposing requirements.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the optical parameter (color temperature) of the light by introducing a colored lens that filters and modifies the light spectrum. By adjusting the lens position and type, the system can change the effective color temperature from warm yellowish (2300K-3800K) to cool white/blue (over 4200K), thereby controlling both illumination intensity and penetration characteristics.

Inventive Principle:
Principle #35Parameter changes

2Illumination intensity

If the color temperature is increased to over 6000K to provide brilliant white light, then the illumination intensity is improved, but the penetration ability deteriorates significantly

Engineering Contradiction:
Improveillumination intensityVSAvoidpenetration ability
Core Design Contradiction:
Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The movable colored lens system allows dynamic switching between different optical states. When the colored lens is positioned in front of the light source, it filters out the blue and violet components of high-color-temperature light, converting it to warmer tones that penetrate rain and fog better, thus resolving the contradiction at high color temperatures.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The colored lens acts as an intermediary between the light source and the environment. It modifies the light properties by filtering specific wavelengths, serving as a mediator that transforms brilliant white/blue light into warmer light with better penetration characteristics while maintaining illumination intensity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If a fixed color temperature lamp is used to provide consistent illumination, then the device complexity is reduced, but the adaptability to different environmental conditions deteriorates

Engineering Contradiction:
Improvedevice complexityVSAvoidadaptability to environmental conditions
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent introduces a movable colored lens with driving members that enable dynamic adjustment of the lens position. This dynamic mechanism allows the lamp to adapt to different environmental conditions (rain, fog, clear weather) by switching between different color temperatures, thereby achieving high adaptability without requiring multiple separate lamps or complex multi-component systems.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The single lamp system with the movable colored lens performs multiple functions: it can provide both high illumination intensity and good penetration ability by switching lens positions, and it can adapt to various environmental conditions. This multi-functionality is achieved within a unified structure, avoiding the need for separate systems for different lighting modes.

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

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 improved illumination and safety by adjusting light color temperature to enhance penetration and visibility during adverse weather conditions, such as rain or fog, by filtering the light to yellow when necessary.

Implementation Method 1

The light from the light source first penetrates the colored lens to generate a color temperature change

Methodology Applied
Scientific EffectLight filtering: Filter (optical)

Implementation Method 2

The light from the bulb is reflected by the reflection trough to center and radiate toward the front of the lamp through the opening

Methodology Applied
Scientific EffectLight reflection: Reflection

AI summary

A lamp color temperature change structure includes a lamp holder, a light source on the lamp holder, a lift unit in front of the light source, and a colored lens mounted to the lift unit. The colored lens is movable and driven by the lift unit to a first position which is away from the front of the light source or a second position which is in front of the light source. The user can select the light from the light source to radiate toward the front of the lamp holder or penetrate the colored lens to generate a color temperature change and then radiate toward the front of the lamp holder according to different environment conditions.
