Remote Light Control Board for Large Fixture Shadow Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light fixtures require manual adjustment of brightness to prevent shadows, which is inefficient and increases power usage, especially in outdoor settings where light sources are spaced closely to minimize shadows, leading to excessive brightness and increased power consumption.
Innovation Solution
A remote light control device with a specific light control board placed behind the lights, allowing for individual control of each light group's brightness based on preset information or control signals, using a matrix format to adjust light emission according to positions and situations, thereby facilitating easy and rapid management of large light fixtures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the distance between light sources is decreased to reduce shadow, then shadow occurrence is reduced, but power consumption increases and brightness becomes excessive
Solution Approach 1:
The patent divides the light sources into multiple independently controllable groups or channels. Each group can be controlled separately to provide targeted illumination in shadow-prone areas without activating all light sources, thus reducing overall power consumption while effectively eliminating shadows where needed.
Solution Approach 2:
The patent implements differential brightness control where different groups of light sources emit different intensities of light based on local requirements. Areas with shadow problems receive higher intensity illumination while other areas use lower intensity, optimizing power consumption while preventing shadow formation only where necessary.
2Object-affected harmful factors
If manual adjustment of brightness is performed to prevent shadow, then shadow occurrence is reduced, but operation efficiency decreases and maintenance becomes difficult
Solution Approach 1:
The patent implements automated control systems that can adjust light source groups independently based on detected shadow conditions or pre-programmed scenarios. The system self-regulates brightness distribution without requiring manual intervention, thereby eliminating shadows while maintaining high operational efficiency and ease of use.
Solution Approach 2:
The patent replaces manual mechanical adjustment of light brightness with electronic control systems. Controllers can be programmed to automatically adjust the intensity of different light source groups, substituting manual operation with automated electronic regulation that improves efficiency and reduces maintenance complexity.
3Object-affected harmful factors
If the number of light sources is increased to reduce shadow, then shadow occurrence is reduced, but device complexity increases and cost increases
Solution Approach 1:
The patent segments existing light sources into multiple controllable groups rather than increasing the total number of light sources. This segmentation allows independent control of different areas, enabling shadow prevention through selective illumination of specific groups without adding more physical light sources, thus avoiding increased device complexity.
Solution Approach 2:
The patent makes each light source group serve multiple functions: they can be individually adjusted to prevent shadows, collectively controlled for overall illumination, and selectively activated based on operational requirements. This multi-functionality allows the existing light sources to handle shadow prevention without requiring additional dedicated light sources, maintaining device simplicity.

AI summary
Proposed is a remote light control device for a large light fixture. Specifically, in the light control device, as in a conventional light control device, first, light emission of each of many groups of lights and each light of the large light fixture is individually controlled according to preset information input according to key manipulation by an administrator or the control signal of an external console 200. In this state according to the embodiment, a light control board which is connected to all lights in each of groups of lights of the large light fixture and individually performs light emission of the lights is installed behind the lights for example.
