Ledflatene

Ledflatene are flat-panel LED lighting fixtures designed for indoor illumination. They provide a slim, diffuse light source and are commonly used as replacements for traditional fluorescent ceiling troffers. A typical ledflate comprises a light-emitting diode array, a diffusion panel, and an LED driver, housed in an aluminum frame or an edge-lit panel.

Edge-lit and back-lit designs: Edge-lit panels route LEDs to the panel edge, with light guided through a diffuser to create a uniform surface glow. Back-lit panels have LEDs behind the diffuser and can offer higher brightness. Sizes commonly include 600x600 mm and 600x1200 mm, with thicknesses from 9 to 15 mm. They operate on standardized AC power with constant-current drivers and may feature dimming interfaces such as 0-10 V, DALI, or phase-cut dimming.

Color temperature ranges from warm white (2700–3500 K) to neutral (4000–5000 K) and daylight (5000–6500 K). Color rendering index (CRI) is typically above 80, enabling accurate color perception. Luminous efficacy often exceeds 100 lumens per watt, depending on model and driver efficiency. Lifespan commonly ranges 30,000 to 100,000 hours, with lumen maintenance rated to 70–90% at end of life.

Ledflatene offer advantages including high energy efficiency, low heat output, and reduced maintenance due to long service life. They provide uniform illumination with minimal glare and can improve office comfort and visual performance. Challenges include higher upfront cost compared with fluorescent fixtures, thermal management requirements, and the need for proper electrical integration and compliance with local lighting standards.

Applications span offices, schools, healthcare facilities, retail spaces, and transit areas, where recessed or surface-mounted flat panels create a clean, uninterrupted ceiling line. Proper selection considers brightness, color temperature, CRI, dimming compatibility, and installation method.
