If you are searching the LED Strips on the internet, you will find some LED Lights named COB LED Strips, so what’s COB and why we say it’s the future of LED Strips.
- What is COB?
COB is the abbreviation for chip on board, which means the LED Chips were packed on the PCB board directly, not like the SMD LEDs that the LED Chips were fixed on the brackets. the COB refers to the mounting of a bare LED Chip in direct contact with a substrate to produce LED arrays, which allows for a much higher packing density of the LED array, results in higher intensity and greater uniformity of light, no light dots and dark area. can greatly reduce the footprint and energy consumption while keeping light output constant.
2. How To Produce the COB LED Strips?
when the manufacturer begins to produce the COB LED Strips, they will put the COB LEDs side by side down the center of the LED Strips, so maybe there are 320, 540, 720 or 894PCS LEDs per meter, there is a phosphor layer over the LEDs like the photo shows above. which will balance out the color temperature while also acting like a protective layer for the tiny LED Chips.
3. Advantages Of COB Strip Lights.
- No Light Dots: because there are more LED Chips on the LED Strips per meter and the LED Chips was put side by side closely, the strip illuminates a smooth, consistent light from start to finish. the uniform light has no dark area and much more attractive to the human’s eyes. bring the steady light even in a tight place.
- More Bright: yes, because the COB LED Strips have more LEDs per meter, so it looks brighter than the SMD LED Strips, the bright light also emits at a wider angle and will spread at 180° off the Strips.
- More Flexible: because on the COB LED Strips the LED Chips put in an array with smaller sizes, which makes it more flexible and bendable.
- Working Voltage: DC12V/DC24V, you can choose two working voltage COB LED Strips, but if you want a longer run length, we will recommend the DC24V.
- Colors: there are still many colors available, you can choose the various color temperatures warm white, neutral white, cool white, other single colors and RGB.
Compared to the SMD LED Strips, the LED Strips with COB brighter and flexible, the color rendering index can reach 90, perfect for various indoor and outdoor linear lighting projects, excellent efficiency and color consistency, incredibly bright and comfortable visual experience. so we believe the COB is the future for the Flex LED Strips.
