Differences Between SMD LED Downlights And COB
Have you ever wondered about the actual light source for LED downlights ? The two most popular types of LED downlights are SMD (surface mount diodes) and COB (chip on board) downlights. Both produce high-quality light, have a high life expectancy, and are very efficient. What are SMDs (surface mount diodes)? SMDs are more efficient than COBs because the light source produces more lumens per watt, which means they produce more light at a lower wattage. They produce a wider beam of light that extends over a larger area. This means that the heat sink requires less material, which in turn means they are cheaper. Because SMD diodes (LED chips) are machine printed on PCB boards, the manufacturing process to make them is more expensive. Most home downlights use SMD LEDs. SMD downlights are covered with frosted reflectors that hide the LED chipset and evenly diffuse the light. SMD LED Downlight What is COB (CHIP A BORDO)? In contrast to a range of LEDs s...
