cob light source is a high light efficiency integrated surface light source technology where the led chip is directly affixed to the mirror metal substrate with high reflectivity. This technology eliminates the concept of support, no plating, no reflow, no patch process, so the process is reduced by nearly 1\/3, the cost is also saved by 1\/3, in popular terms, is more advanced than led lights, more eye protection lights.
The difference between Cob lamp and led lamp is that led lamp can save environmental protection, no stroboscopic, no ultraviolet radiation, and the disadvantage is the harm of blue light. Cob lamp high color rendering, light color close to natural color, no stroboscopic, no glare, no electromagnetic radiation, no ultraviolet radiation, infrared radiation can protect the eyes and skin.
So comprehensive evaluation, or cob lamp is better!
