Product Overview
Series Definition
The 360 LiteOn designation refers to products engineered to emit light across a full 360 degrees, eliminating shadows and providing uniform illumination. The series includes:
- 360 LiteOn LED Lamp (Model L360‑LED)
- 360 LiteOn LED Panel (Model L360‑P)
- 360 LiteOn Ambient Light (Model L360‑A)
Key Features
Primary attributes of the 360 LiteOn series are:
- Full‑360 illumination achieved through engineered reflector arrays.
- High luminous efficacy ranging from 120 to 150 lumens per watt.
- Integrated dimming and color‑temperature control via PWM drivers.
- Low thermal dissipation facilitated by advanced heat‑sink materials.
- Compliance with IEC 62471 photobiological safety standards.
Design and Technical Specifications
Optical Architecture
The 360 LiteOn lamps employ a concentric reflector array made of anodized aluminum. The array is coupled with a micro‑lens array fabricated through precision injection molding. This combination achieves a uniform light distribution profile measured as 1° beam angle at the 80% intensity contour, expanding to 360° across the surface. The optical design also incorporates a low‑reflectance coating to mitigate glare while preserving color fidelity.
Electrical Configuration
Each device is powered by a 12‑V or 24‑V DC input, depending on the model. The driver circuitry utilizes a synchronous buck converter, offering a constant current output of 350 mA for the L360‑LED lamp, 400 mA for the panel, and 300 mA for the ambient light. PWM dimming is implemented at 25 kHz to reduce audible flicker. The drivers incorporate a thermal shutdown feature that activates at 70 °C, ensuring reliability in enclosed fixtures.
Thermal Management
Heat dissipation is addressed through a two‑stage approach. First, a copper heat spreader distributes thermal energy across the LED die, reducing hotspots. Second, a finned aluminum heat sink with a thermal interface material (TIM) achieves a thermal resistance of 6 °C/W. Combined, the design maintains junction temperatures below 80 °C under full load, extending LED lifespan to an estimated 30,000 hours.
Packaging and Form Factor
Packaging options vary: the L360‑LED lamp adopts a standard 2 × 4 in. enclosure with a detachable LED assembly, while the panel version uses a 4 × 4 in. modular design that can be tiled. The ambient light is available in a 3 × 3 in. format, optimized for wall‑mounted installations. All models feature a protective polycarbonate housing rated IP65, providing resistance against dust and splashing water.
Manufacturing Process
Component Sourcing
LiteOn sources LED chips from leading semiconductor suppliers, selecting dies with an InGaN active layer for high color rendering index (CRI > 90). Reflector and lens materials are fabricated in-house to ensure quality control. The company maintains a Just‑In‑Time inventory system to reduce stockholding costs.
Assembly Workflow
Assembly begins with soldering the LED die onto a high‑density substrate. After reflow, the substrate is mounted onto the heat sink and integrated with the driver board. The optical components are then inserted and aligned with a precision jig. Automated optical inspection verifies light output uniformity, while thermal imaging confirms junction temperatures under load.
Quality Assurance
Quality control follows ISO 9001 standards. Each batch undergoes photometric testing, lifetime cycling, and compliance checks for UL 924 and IEC 60825. Test data is logged in a traceability database, allowing for rapid recall if necessary. The company also performs field testing in representative indoor environments to validate performance under varied ambient conditions.
Applications and Use Cases
Residential Lighting
The 360 LiteOn series is well suited for modern living spaces where soft, uniform illumination enhances aesthetics. The L360‑A ambient light is frequently incorporated into recessed ceiling fixtures, providing indirect lighting that reduces eye strain. Homeowners can program the dimming curves via smartphone apps, creating ambience for different times of day.
Commercial Interiors
Office environments benefit from the uniform distribution of the L360‑P panel, reducing glare on computer monitors and enhancing productivity. Retail stores employ the ambient light in display fixtures to highlight merchandise while maintaining a cohesive lighting theme. The modular nature of the panel facilitates flexible layout adjustments during renovations.
Industrial and Warehouse Settings
Industrial sites require high illumination levels and durability. The L360‑LED lamp’s robust housing and high luminous efficacy reduce maintenance costs. In warehouses, the lamp can be integrated into track lighting systems, delivering consistent brightness across storage aisles. Its low operating temperature also allows for prolonged operation in high‑humidity environments.
Architectural and Outdoor Lighting
Architectural projects use the L360‑P panel as accent lighting along façades, creating visual depth without harsh glare. Outdoor installations, such as street lighting, benefit from the lamp’s weather resistance and uniform distribution, ensuring pedestrian safety. The series’ compliance with ECE and IEC outdoor standards enables deployment in varied climatic zones.
