Edge Light
LED Strip
Bar
High-power OSRAM SMD3535 chips on a 1.6mm aluminum substrate — paired with Mitsubishi PMMA 99% transmittance lens for uniform 10x30 degree side-emitting illumination. PT4115 constant current IC ensures consistent brightness across every unit.




High-Power Side-Emitting LED Bar
The NPHIS Edge Light LED Strip Bar is engineered for lightbox, signage, and display applications where uniform side-emitting illumination is critical. Built on a 1.6mm aluminum substrate with OSRAM SMD3535 chips, Mitsubishi PMMA optical lens, and PT4115 constant current IC — delivering consistent, high-lumen output with exceptional uniformity across the entire panel.
Why Choose NPHIS Edge Light
Six key engineering advantages that make the NPHIS Edge Light LED Strip Bar the preferred choice for professional lighting designers.
OSRAM SMD3535 — Premium Tier Chip Quality
The OSRAM SMD3535 chip is a high-power, high-reliability LED package trusted by leading lighting manufacturers worldwide. Its larger 3.5x3.5mm footprint delivers superior lumen output per chip compared to standard 2835 or 3030 packages, while the OSRAM binning process ensures exceptional color consistency across batches.
- OSRAM SMD3535 — globally recognized premium chip brand
- Tight binning: <3 SDCM color consistency
- High lumen output: up to 200 lm per chip
- Excellent thermal stability for long-run installations
- 50,000-hour rated lifespan at L70

Mitsubishi PMMA Lens — 99% Light Transmittance
The optical lens is manufactured from Mitsubishi PMMA (polymethyl methacrylate) material, achieving 99% light transmittance — the highest available in the industry. This ensures maximum light output efficiency and eliminates yellowing or degradation over time, maintaining consistent optical performance throughout the product lifespan.
- Mitsubishi PMMA: 99% light transmittance
- No yellowing or optical degradation over time
- Precision-molded for consistent beam uniformity
- UV-resistant for long-term stability
- Superior to standard PC or acrylic lens materials

PT4115 Constant Current IC — Uniform Brightness
The PT4115 is a high-efficiency constant current LED driver IC that ensures each LED chip receives precisely regulated current regardless of supply voltage fluctuations. This eliminates brightness variation between bars — a critical requirement for large-format lightboxes and display walls where multiple bars must match perfectly.
- PT4115 constant current IC on every bar
- Eliminates brightness variation between units
- Stable output despite input voltage fluctuations
- PWM dimming compatible (100–3000Hz)
- Essential for multi-bar lightbox installations

1.6mm Aluminum Substrate — Superior Heat Dissipation
The 1.6mm aluminum substrate provides a rigid, thermally conductive base that efficiently transfers heat away from the LED chips. Unlike flexible PCB strips, the aluminum substrate maintains its shape under high-power operation and provides a stable mounting surface for precise optical alignment of the lens.
- 1.6mm aluminum substrate for rigidity and heat dissipation
- Thermal conductivity: 1.0 W/(m·K) minimum
- Maintains shape under continuous high-power operation
- Stable platform for precise lens alignment
- Compatible with standard aluminum profile channels

10x30° Beam Angle — Optimized for Edge Lighting
The 10x30 degree asymmetric beam angle is specifically engineered for edge-lit panel applications. The narrow 10-degree axis directs light efficiently into the light guide panel, while the 30-degree axis provides the spread needed for uniform illumination. This precise beam control maximizes efficiency and minimizes hotspots at the panel edges.
- 10x30° asymmetric beam — optimized for light guide panels
- Maximizes coupling efficiency into the panel
- Minimizes hotspots at panel edges
- Suitable for panels from 10mm to 50mm thickness
- Custom beam angles available on request
