RGB CCT COB LED-Strips

Why The COB LED Strips Are More Popular Than SMD’s?

If you want to add some LED Lights that are flexible, bendable and cuttable, we will recommend using the LED Strip Lights, but now more and more users will choose the COB LED Strips, not the SMD LED Tapes. today let’s check the advantage of COB LED Lights.

RGB COB LED Tapes

“COB” is the abbr chip-on-board technology, the newest technology of packaging the LED Chips, 320PCS/480PCS/520PCS or 840PCS LED Chips are mounted on every meter flexible PCB board to allow high density LED array. to create a totally smooth, seamless line of light, this outstanding design will not show any visible light dots or hot spots, making it ideal illumination for reflective surfaces, such as countertops, tile floors, jewelry cases and backlighting.

Advantages:

  • More Bright
  • No Visible Light Dots And Hot Spots
  • 90+ High CRI

Due to the high-density LED Chips packaging technology, the COB LED Strips are more bright than the SMD’s, the max LEDs that can be mounted on every meter PCB board is 144PCS, but for COB, the number increased to 840PCS. the more Light Chips mean the COB LED Lights are more bright, you will not see any visible light dots and hot spots. from the photo below, you will see the difference:

COB LED Strips Advantage

the COB LED Tapes with a higher CRI(color rendering index) value, the value of single color is 90+ and multiple colors is 80+, with the higher CRI, the reflection of lighting on the products look more natural, which makes the subject outstanding in color and features of materials, perfectly reflecting the colors of subject and the human beings. it’s an ideal lighting solution for stores that sell fruits or foods.

Color Rending Index

the COB LED Strips are flexible, bendable and cuttable too, the width from 2.7mm to 12mm for various applications, you can take single colors like warm white, white, natural white, red, blue, yellow, purple, etc, the multiple colors are available: RGB, RGBW, RGB+CCT, Dream color. you can choose the different waterproof level products for your projects from IP20, IP65, IP68 and IP68.

Now the price of COB LED Lights is very close to the SMD’s, so if you want to get a better result for your lighting projects, we will strongly recommend the COB LED Lights.

 

What’s CRI?How To Choose The Right One?

When you choose the different LED Lights, you will find some LED Lights that mark the CRI value, 80Ra, 85Ra or 90Ra, so the question is, what is CRI? how to choose the right one?

Color Rending Index

CRI is the abbreviation of the color rending index, the high CRI value will make the subject more natural. if use the high CRI LED Lights that makes the subject outstanding in color and features of materials, perfectly reflecting the colors of subject and the human beings. it’s an ideal lighting solution for stores that sell fruits or foods.

Ra is the average from R1 to R8, we should not only take attention to average Ra but also on the situation red special R9 and the average Ra(9-12) of red, yellow, green, blue when designing high CRI LED studies have found that there is a gap between the RA and the visual evaluation for the color of the white LED, the color fo the white LED with the lower Ra maybe looks beautiful, the color of the white LED with the higher Ra will look ugly. it can bed ensured the high CRI of white LED when Ra and R9 are both on high value.

R9 refers to a saturated red, with a wavelength of 650nm when the R9<0, the red light is not enough, the red serious distortion, so the lamp can not render in the red color naturally, the number bigger the conductibility of the red light is better, whatever, the R9 bigger, the effect on irradiation in fruit and flowers better, they are more bright-colored, especially, the product is used for commercial lighting, the R9 can not be negative.

so the value of CRI is higher, the reflection of lighting on the products look more natural. so that’s why CRI98 is better than CRI95, and absolutely, the products with higher CRI value, the price is more expensive. if you are looking for LED Strips with a high CRI value, we will recommend the COB LED Strips, which with high-density LED Chips design, a CRI value of more than 90Ra, NO visible light dots and dark area. you can use them for the home applications or high-end lighting projects.
