01LIGHT BULBS
Integrated brilliance for outdoor illumination
This compact COB module integrates the light source and constant current drive into a single unit, simplifying the construction of high-output fixtures. It is designed for professionals building or repairing projection lights, spotlights, and street lamps.
The chip draws power directly from standard AC voltage, removing the need for separate drivers or intricate soldering. Its superconducting aluminum base handles thermal load, ensuring stable performance in demanding outdoor environments.
02DESIGN
Integrated drive within a compact frame
The Derundahao chip merges the LED array with its constant current driver, creating a self-contained power unit. This integration reduces component count and assembly time, allowing installers to plug in cables directly without managing external ballasts. The design prioritizes efficiency, delivering high luminous flux while maintaining a small physical footprint suitable for modern fixture architectures.
04PERFORMANCE
Wide beam and direct AC connection
Operating on AC 100-260V, the module connects directly to mains power, streamlining installation for streetlights and mining lamps. It projects a 120-degree beam, ideal for broad-area coverage rather than narrow pinpoint focus. With a color rendering index of 70 and 90 lumens per watt, it provides functional white light suited for task-oriented outdoor lighting applications.
05DETAILS
Precise dimensions for easy integration
Measuring approximately 54 by 54 millimetres with a height of 1.5 millimetres, the chip fits neatly into standard housing slots. The light surface itself is a 25-millimetre square, offering a concentrated source area. Weighing just 17 grams, it adds minimal structural load to fixtures, making it a practical replacement for older, bulkier light sources in existing infrastructure.
