  • Flip COB LED

    Flip COB LEDFlip COB LED

    High light density flip COB, this product USES no gold wire packaging, at the same time has the advantages of high central light intensity, uniform light output, high reliability, the size of the product is compatible with the commercial bracket and lens on the market and other related kits. It overcomes the disadvantage that the voltage of the formal chip increases sharply with the increase of the input current and is prone to burn out. At the same time, it can provide more uniform light output effect and higher optical density per unit area. At the same time, the product USES high thermal conductivity and high insulation substrate material, full heat dissipation capacity is more excellent Learn More
