Is COB better than LED?
Although a COB LED is efficient, an SMD LED has an even greater level of efficiency. That’s because more lumens are produced per watt. In other words, you’ll receive more light with less wattage. An SMD LED also produces a broader light beam, which means the light doesn’t need as large of a heat sink as a COB LED does.
What is the product of Epistar?
Epistar specialises in high-brightness LED products, which are used in general lighting, traffic signals, and various consumer products such as mobile phones and laptop computers. The company supplies the LED backlighting for Samsung liquid crystal displays.
Which is better COB or Cree?
Cree LEDs produce a fair amount of heat for a single chip but can disperse that heat easily. COB LEDs produce a similar amount of heat but as a harder time dispersing that heat. That means Cree LEDs may have a longer lifespan than COB LEDs depending on how much use they get.
What does Epistar mean?
Acronym. Definition. EPISTAR. Echoplanar Imaging with Signal Targeting and Alternating Radiofrequency.
What is brighter COB or LED?
Simply put, COB LEDs are brighter, consume less power, and output a higher quality beam of light compared to older LED technologies found in most other trade show lighting today. The next time you are in the market for exhibit lighting, insist on COB LED technology!
Do COB LED get hot?
COB LEDs are high-power components that therefore generate high temperatures.
