Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Outdoor security lighting is typically obtrusive during daylight hours and lacks control over individual light output, limiting its effectiveness.
Innovation Solution
A security light design featuring a mounting base electronically coupled to a sensor head, with independently adjustable light panels that include LEDs and V-shaped recesses for controlled light distribution, allowing for adjustable illumination patterns and reduced visibility during the day.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional outdoor security lighting is used, then illumination function is provided, but visibility during daylight hours increases making it obtrusive
Solution Approach 1:
The light panel utilizes translucent material that appears invisible or minimally visible during daylight hours, effectively changing its optical properties based on ambient light conditions. This resolves the contradiction by maintaining illumination functionality while eliminating the harmful visual obtrusiveness during daytime.
2Illumination intensity
If traditional security lighting is used, then illumination is provided, but control over individual light head output is limited
Solution Approach 1:
The light panel is segmented into multiple independently controllable light-emitting sections, each with its own LED array and V-shaped recesses pattern. This allows individual control of different illumination zones (e.g., front illumination vs. wall wash), resolving the contradiction by providing both sufficient light output and flexible control adaptability.
Solution Approach 2:
The system enables dynamic control of illumination patterns by independently adjusting the intensity and activation of different light panel sections based on sensor input and operational requirements. This dynamic adaptability resolves the contradiction between maintaining adequate illumination and providing control flexibility.
3Illumination intensity
If V-shaped recesses are added to light panel, then light distribution control is improved, but manufacturing complexity increases
Solution Approach 1:
The V-shaped recesses are designed with specific geometric parameters (angles, depths, spacing) that optimize light distribution while remaining compatible with standard manufacturing processes. By carefully selecting these parameters, the system achieves improved light distribution control without excessively increasing manufacturing complexity.

AI summary
A security light having a first and a second light panel is set forth. The light panels includes a plurality of light scattering structures which are V-shaped grooves extending from the top surface to the bottom surface along the height of each of the light panels. The light scattering structures may modify in density as the distance from the light source increases in order to improve the light output performance of the panes.
