Light Guide Plate Desk Lamp Glare Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional desk lamps do not effectively address glare and shadow issues, which can negatively impact users, especially in dark environments, and lack the ability to adapt lighting based on user activity or operation modes.
Innovation Solution
A light guide plate desk lamp with an LED module, power input module, and control panel that adjusts light emission and color temperature based on user input and sensing data, including operation modes and user motion, to minimize glare and shadows.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional desk lamps emit light directly, then illumination is provided, but glare and shadows are generated
Solution Approach 1:
A light guide plate is introduced as an intermediary component between the LED light source and the desk surface. The light guide plate diffuses and redirects light, transforming direct harsh illumination into soft, uniform lighting that eliminates glare and shadows while maintaining effective illumination.
Solution Approach 2:
The light guide plate creates non-uniform light distribution with higher intensity at the center and gradually decreasing intensity toward edges, optimizing illumination quality for reading areas while preventing glare in peripheral regions.
2Device complexity
If desk lamps provide fixed lighting, then simple structure is maintained, but adaptability to user needs is limited
Solution Approach 1:
The desk lamp incorporates adjustable features including variable color temperature (warm to cool white), adjustable brightness levels, and movable lighting zones through the light guide plate. These dynamic adjustments allow the lamp to adapt to different user needs, times of day, and tasks while maintaining a relatively simple overall structure.
Solution Approach 2:
The light guide plate serves multiple functions simultaneously: it diffuses light to eliminate glare, creates uniform illumination patterns, enables color temperature adjustment, and provides brightness control. This multi-functionality reduces the need for separate components, maintaining structural simplicity while enhancing adaptability.
3Object-affected harmful factors
If light guide plate is added to diffuse light, then glare is reduced, but device complexity increases
Solution Approach 1:
The light guide plate integrates multiple optical functions (diffusion, redirection, uniformity control) into a single component. By merging these functions into one element rather than using separate diffusers, reflectors, and lenses, the design reduces overall device complexity while effectively eliminating glare.

Function Achieved in This Case
The solution effectively reduces glare and shadow generation, providing custom-tailored lighting that adapts to user needs, enhancing user comfort and visual experience.
Implementation Method 1
an LED element of the LED module may emit light as power is applied to the power input module, and the light emitted from the LED module may be emitted through the light guide plate
Data Source
AI summary
A light guide plate supported by at least one frame. An LED module is arranged on at least one side of the light guide plate, and a power input module is supported by at least one frame. When power is applied by the power input module, LED elements of the LED module emit light, and light emitted by the LED module is emitted through the light guide plate.
