Dual-Source Clamping Lamp for Monitor Brightness Contrast
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing lighting solutions for monitors often create high brightness contrast between the screen and the surrounding environment, leading to user fatigue due to inadequate illumination behind the monitor.
Innovation Solution
A clamping lamp with dual light sources, one positioned above the monitor's top surface for front illumination and another below for rear illumination, along with a light-controlling method that adjusts luminous intensity based on environmental illuminance and distance to reduce brightness differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If only front lighting is provided for the monitor, then the illumination of the display area is sufficient, but the brightness contrast between the screen and the wall behind the monitor becomes too high, causing user fatigue
Solution Approach 1:
The lighting system is segmented into two independent light sources: a first light source positioned above the monitor top surface for front illumination, and a second light source positioned below the top surface for rear illumination. This segmentation allows each light source to independently control the illumination of different zones, solving the brightness contrast problem by providing both front and rear lighting simultaneously
Solution Approach 2:
Different regions of the monitor are provided with different lighting qualities: the first light source provides directed illumination to the front display area, while the second light source provides illumination to the rear wall area. This local quality differentiation ensures that each zone has appropriate brightness levels, reducing the harmful brightness contrast while maintaining sufficient display illumination
2Device complexity
If a single light source is used above the monitor, then the structure is simple, but the ability to reduce brightness contrast is insufficient
Solution Approach 1:
The lighting system is divided into two separate clamping components: a first clamping component holding the first light source, and a second clamping component holding the second light source. This structural segmentation enables independent positioning and control of each light source, allowing the system to effectively reduce brightness contrast while maintaining reasonable structural complexity
Solution Approach 2:
Both the first and second light sources are integrated into a single clamping lamp assembly that can be mounted on the monitor together. This merging allows the dual-light-source system to function as one unified device, providing brightness contrast reduction capability without requiring two separate lighting devices, thus balancing structural complexity with functional effectiveness
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
The solution effectively reduces eye strain by minimizing brightness contrast between the front and rear of the monitor, providing a more comfortable viewing experience by balancing illumination across both zones.
Implementation Method 1
The first light source is configured to emit light toward a first zone that the front surface faces toward when the first light source is turned on
Implementation Method 2
The second light source is configured to emit light toward a second zone that the back surface faces toward when the second light source is turned on
Implementation Method 3
the second clamping component further includes a light-transmitting cover configured to cover the second light source and to allow light emitted by the second light source to pass through

AI summary
A clamping lamp for clamping a monitor comprises a first light source and a clamping body including a second light source, a first clamping component including a first clamping portion and a lamp connection portion, and a second clamping component including a second clamping portion. The lamp connection portion connects with the first clamping portion and the first light source. The first clamping portion leans against a front surface of the monitor and the second clamping portion leans against a back surface of the monitor when the clamping lamp clamps the monitor so the first light source is located above a top surface of the monitor. The first light source emits light toward a first zone that the front surface faces toward. The second light source emits light toward a second zone that the back surface faces toward.
