Donya DN31<\/span><\/strong>\u00a0is a value-engineered recessed downlight from\u00a0<\/span>Alton Ray<\/span><\/strong>, specifically developed for large-scale residential projects where budget optimization is a primary consideration without compromising on basic lighting quality. With a 15cm diameter and 12W power consumption, this luminaire addresses the needs of apartment buildings, residential corridors, and common areas, offering a practical balance between initial cost and long-term reliability.<\/span><\/p>\n

EPISTAR LED Chips \u2013 Performance at the Right Price<\/span><\/h4>\n

At the core of the DN31 are\u00a0<\/span>EPISTAR<\/span><\/strong>\u00a0LED chips, sourced from one of Taiwan’s leading semiconductor manufacturers. These chips provide a proven balance of performance and cost-effectiveness, delivering\u00a0<\/span>1,080 lumens<\/span><\/strong>\u00a0of luminous flux with\u00a0<\/span>90 lumens per watt<\/span><\/strong>\u00a0efficacy. The\u00a0<\/span>Color Rendering Index (CRI > 80)<\/span><\/strong>\u00a0ensures natural color reproduction, creating comfortable visual environments for residents and visitors alike. The\u00a0<\/span>120\u00b0<\/span><\/strong>\u00a0wide beam angle guarantees uniform illumination across standard residential spaces, minimizing dark spots and reducing the number of fixtures required per area.<\/span><\/p>\n

Lightweight Construction with Efficient Thermal Design<\/span><\/h4>\n

Weighing just\u00a0<\/span>0.42 kg<\/span><\/strong>, the DN31 is one of the lightest fixtures in its class \u2013 a significant advantage for suspended ceiling installations where structural load must be carefully managed. The shallow\u00a0<\/span>52mm<\/span><\/strong>\u00a0depth allows installation in ceilings with limited plenum clearance, making it suitable for both new construction and retrofit projects. The integrated\u00a0<\/span>aluminum heat sink<\/span><\/strong>\u00a0effectively dissipates heat, maintaining junction temperatures within the\u00a0<\/span>\u201330\u00b0C to +50\u00b0C<\/span><\/strong>\u00a0safe operating range and preserving LED lifespan. The\u00a0<\/span>ABS+Aluminum<\/span><\/strong>\u00a0hybrid housing provides mechanical durability while keeping weight to an absolute minimum.<\/span><\/p>\n

Ideal for Residential and Common Areas<\/span><\/h4>\n

With its\u00a0<\/span>IP52<\/span><\/strong>\u00a0ingress protection rating, the DN31 offers reliable performance in residential environments where dust and occasional moisture are present. Its key applications include:<\/span><\/p>\n

    \n

  • \n

    Renovation projects<\/span><\/strong>\u00a0where cost control is a primary concern<\/span><\/p>\n<\/li>\n<\/ul>\n

    The high-quality\u00a0<\/span>PP diffuser<\/span><\/strong>\u00a0ensures smooth, glare-free light distribution across the wide 120\u00b0 beam angle, enhancing visual comfort in everyday living spaces.<\/span><\/p>\n

    Flexible Color Temperature Options<\/span><\/h4>\n

    Available in\u00a0<\/span>three standard color temperatures<\/span><\/strong>, the DN31 adapts to various residential design preferences:<\/span><\/p>\n

      Cool White (6500K):<\/span><\/strong>\u00a0Suitable for utility areas, garages, and high-traffic corridors<\/span><\/p>\n<\/li>\n<\/ul>\n

      Optimized Packaging for High-Volume Projects<\/span><\/h4>\n

      Each unit is supplied in an individual\u00a0<\/span>corrugated box<\/span><\/strong>, with master cartons containing\u00a0<\/span>24 units<\/span><\/strong>\u00a0at dimensions of\u00a0<\/span>40.7 \u00d7 38.8 \u00d7 40.1 cm<\/span><\/strong>. This optimized packaging density reduces shipping costs and storage footprint \u2013 a critical consideration for large-scale residential developments with high fixture counts.<\/span><\/p>\n
