System Architecture Overview
Our novel four-source configuration ensures uniform irradiance while maintaining strict thermal safety limits. The system integrates real-time feedback loops for precise control, eliminating the "blind spots" found in traditional overhead projectors.
360° Coverage
Maximizes skin surface exposure area.
Active Cooling
Maintains skin temp < 37°C safely.
Irradiance Control
Adjustable up to 50 μW/cm²/nm.
Safety Interlocks
Auto shut-off for thermal events.
Simulation & Validation
Optical Irradiance Simulation
Full four-source ray-tracing simulations performed in TracePro confirm that the configuration achieves comprehensive 360-degree coverage. The system delivers a uniform irradiance of 30 μW/cm²/nm across the entire neonatal body surface, effectively eliminating the shadow zones common in single-source devices.
- Validated >0.7 uniformity ratio across curved surfaces.
- Confirmed zero shadow zones on lateral aspects.
Mechanical Modeling & Assembly
Comprehensive 3D mechanical simulations in SolidWorks were instrumental in defining the final structural architecture. We utilized the CAD environment to validate the precise integration of the four-source array, cooling channels, and adjustable mounting mechanisms, ensuring robustness and ease of assembly.
- Confirmed interference-free fit for 150+ components.
- Validated structural integrity of moving gantry parts.
Design Evolution
Initial Overhead Model
The original prototype utilized a single overhead light source. Testing revealed significant shadowing on the lateral aspects of the patient, reducing therapeutic efficacy by 40%.
360-Degree Illumination
Incorporating four synchronized LED panels surrounding the patient bed. This iteration achieves a 0.72 uniformity ratio and eliminates shadowing, ensuring consistent bilirubin breakdown regardless of patient positioning.
