Traditional LED lamps require a separate constant current driver for each fixture, making installation cumbersome and costly. TYF’s constant voltage COB utilizes multiple constant voltage ICs connected in series within the COB light source, achieving a “one-to-many” drive method. A single constant voltage power supply can drive multiple parallel lamps, automatically maintaining constant current for safer operation. This design reduces driver costs by approximately 70%, simplifies installation, and improves efficiency.
Through continuous research and development, TYF Tongfang has upgraded its second-generation TBH constant-voltage COB lamps, boasting a 40% increase in luminous efficacy, superior color consistency, improved spot quality, lower IC power consumption, and more stable constant current. It supports one-to-many lighting applications, boasts high power output of 5-20W, low voltage of 24V, and intelligent dimming from 2700-6000K. Its compact size makes it suitable for miniaturized lamps and facilitates space layout design.


Environmental Applications
Home Lighting: Constant-voltage COB light sources support intelligent dimming and color adjustment from 2700-6000K, meeting the personalized needs of living rooms, bedrooms, kitchens, and other scenarios. Recessed downlights can be used to create ambiance and enhance comfort.
Commercial Lighting: Constant-voltage COB light sources offer excellent spot quality with an Ra value greater than 90, faithfully reproducing product colors and enhancing appeal. Focused on high luminous efficacy and energy efficiency, they are suitable for retail spaces, showrooms, and other scenarios.


Accent lighting: By precisely controlling light direction and intensity, specific areas or objects are highlighted, creating a sense of visual focus and depth. Its high color rendering, flexible light distribution, and stable driving characteristics make it an ideal choice for accent lighting.
Office lighting: Focusing on illumination uniformity and eye comfort, it is suitable for use in meeting rooms, open workspaces, and other settings, protecting eyesight and reducing visual fatigue.
