Product features: 1 Advantages of COB surface light source: 1. It can be freely matched and combined to form a variety of LED lamps, which are easy to assemble. 2. High reliability, no dead light, no plaque. 3. Even light, soft light, no glare, no harm to eyes. 4. High color rendering index and high luminous efficiency. 5. Under normal current, the attenuation is the minimum, which is less than 3% within 1000H. 6. It is safe and reliable, all of which work below 50V, which fully considers the application certification. 7. It is green and pollution-free. 2 Aluminum alloy frame: 1. It is customized by mold opening. Precise electrophoresis process is adopted in the production process, rather than painting, painting and other processes. Precise and scientific electro ion technology guarantees the products exquisite, noble, classic, fadeless, scratch resistant and other characteristics. 2. Excellent thermal conductivity and corrosion resistance 3 Lamp cover (made of pc material) 1. It has high strength and elastic coefficient, high impact strength and wide range of application temperature; 2. High transparency and free dyeing; 3. Low forming shrinkage and good dimensional stability; 4. Good fatigue resistance; 5. Good weather resistance; 6. Excellent electrical characteristics; Insulation performance: excellent (it can work well even under humid and high temperature)
