AC DOB LED Made in China 50watt Dob Led Chips

COB: Chip-on-Board LED: In contrast to the SMD technology, COB LED lights package multiple LED chips together, instead of spreading the LEDS on the surface. This makes COB lights brighter than SMD bulbs (lumen per watt ratio). COB lights shine bright, but cannot change colour like SMD bulbs.

DOB: Driver-on-Board LED: This new LED technology is often used for downlights, solving the problem of needing a separate LED driver. Unlike other non-DOB bulbs, the DOB technology used by ECO Lights uses an AC current instead of AC converted to DC. It makes downlights more reliable, energy efficient and reduces the heat a LED light can produce.

Guangmai is a photoelectric lighting high-tech enterprise integrating development, production, sales and after-sales service, specializing in the production of LED, integrated, high-power LED and COB light sources, SMD2835, 3030, 3535 and other light sources.

The company's SMD patch LED series products use imported chips, high luminous efficiency, narrow spectrum, good monochromaticity, high color rendering, green environmental protection, precision constant current, life expectancy of 50,000 hours, low attenuation, high brightness, low attenuation, energy consumption Small, long service life. Strong antistatic ability, high brightness, good color consistency; low illumination, long life, etc.

The product adopts integrated high-power LED light source, and the voltage, power, color temperature, size, color change, internal and external control can be set by the customer. The products can be widely used in roads, bridges, squares, garden landscape areas, residential and commercial areas, courtyards, hotels, hotels, shopping plazas, dance halls, theaters, offices, homes and other living, leisure and entertainment places.
