What is COB LED chip?
Chip-on-Board or “COB” refers to the mounting of a bare LED chip in direct contact with a substrate (such as silicon carbide or sapphire) to produce LED arrays. Most notably, COB technology allows for a much higher packing density of the LED array, or what light engineers refer to as improved “lumen density”.
What is better COB or LED?
But the difference between LED light COB and SMD is that COB LEDs have more diodes. COB chips typically have 9 or more diodes. COB is known for better lumen-per-watt ratios and heat efficiency. This has a lot to do with the design of COB LEDs, and the cooling ceramic substrate of the chips.
What’s brighter COB or SMD?
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 difference between COB and LED?
The SMD LED light source is a single patch LED lamp bead with a light-emitting diode directly attached to the surface. COB LED light source packaging technology is a direct chip package on the board, COB has improved light efficiency, improved glare effect of LED lights, and reduced light loss.
Are COB lights any good?
While COB LEDS do provide an excellent light intensity, they’re not exactly the best when it comes to spread, because COB LEDs are a single-point light source (meaning all light comes from a single point in space).
What does COB mean in LED lights?
chip on board
Relatively new to the LED market, chip on board (COB) LEDs offer many advantages over the standard options. COB LEDs are basically multiple LED chips (typically nine or more) bonded directly to a substrate by the manufacturer to form a single module.
Are COB LED lights good?
What is the Cree LED?
What is a CREE LED light? Cree is an LED lighting technology and one of the most innovative lighting solutions on the market. This lighting technology includes mercury-free LED technology. This technology goes beyond traditional lighting systems that are becoming increasingly obsolete.
Are COB LED lights dimmable?
Dimmable. Dimming LED corn cob light bulbs gives you the same kind of flexibility and control you can expect from your incandescent bulbs. Customers also use these dimmers for track lighting–where desirable ambient light levels are needed but where a dimmed light setting is also desirable.
How long do COB LEDs last?
A COB LED has an average rated lifetime of 50,000 hours.
What is COB (chip-on-board)?
Chip-on-Board or “COB” refers to the mounting of a bare LED chip in direct contact with a substrate (such as silicon carbide or sapphire) to produce LED arrays. LED technology is constantly being improved to improve performance, create more use cases, and make it more versatile.
What are cob LEDs and how do they work?
COB LEDs are basically multiple LED chips (typically nine or more) bonded directly to a substrate by the manufacturer to form a single module. Since the individual LEDs used in a COB are chips and not traditionally packaged, the chips can be mounted such that they take up less space and the highest potential of the LED chips can be obtained.
What is a chip-on-board led?
The Chip-on-Board (COB) LED is one of the latest and most advanced entrants to the LED market, but what is it that makes these LEDs much brighter, consume less power, and output a higher quality beam than the older LED technologies?
How long will the 6W COB LED trade show light run?
In fact, our 6W COB LED Trade Show Light will run 14-15 hours using our very small and light weight (1.25lbs) rechargeable Mobile Power Center. High quality light output over extended periods of time using a relatively small battery was simply not possible just a few short years ago!
