LEDPanels

LEDPanels are flat, ceiling-mounted luminaires that use light-emitting diodes as the primary light source. They are designed to produce a uniform, diffuse light across a large area and are commonly used as replacements for traditional fluorescent ceiling troffers in offices, schools, retail spaces, and healthcare facilities. The light is typically emitted through a translucent diffuser or light guide plate, creating minimal glare.

Construction typically consists of an aluminum frame or housing, a LED light source array, a diffuser made of acrylic or polycarbonate, and a driver that regulates current to the LEDs. Some panels are edge-lit, where LEDs are placed on the perimeter and light travels through a light guide, while others are back-lit with LEDs distributed behind the diffuser. Panels can be modular for different sizes and mounting heights.

Performance characteristics commonly include lumen output ranging from several hundred to several thousand lumens per panel, color temperatures from warm to cool (approximately 2700K to 6500K), and color rendering indices in the 80s to 90s. Typical efficiencies are in the high teens to over 100 lumens per watt, depending on design. Lifetimes are often 50,000 to 100,000 hours.

Applications include offices, educational rooms, retail storefronts, and medical facilities. They can be installed in suspended ceilings or mounted on walls, and many panels support dimming and smart controls. Proper thermal management and uniform diffusion are important to maintain color consistency and reduce flicker.

Standards and safety considerations commonly require compliance with local electrical codes and certifications such as UL, CE, or RoHS. Selection factors include brightness, color, glare control, dimming compatibility, and maintenance expectations.
