A COB light is a type of LED light, with COB standing for Chip-On-Board. COB lights are essentially an array of LED chips that are tightly packed together and bonded to a substrate such as silicon carbide.Those types of singular round LEDs are called DIP LEDs, or Dual In-Line Package.
What is the difference between LED and COB?
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. With COB packaging technology, labor and manufacturing costs are 5% less than SMD. And life expectancy is much higher than traditional SMD.
Which 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.
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 on LED lights?
Chip on Board
Taking you back to your secondary school days for a few moments here… COB, or Chip on Board is a fairly new member of the LED family. Multi LED chips are packed closley together as one lighting module. And when it light up, it appears like more of a lighting panel than multiple individual lights if that makes sense.
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.
Do COB LED get hot?
COB LEDs are high-power components that therefore generate high temperatures.
Are COB LEDs dimmable?
Dim-to-Warm is COB LED which works like halogen lamp when dimmed. Its specialty is that when you dim it the color temperature gets warmer. Usually dimming does not affect the color temperature of the LED.It’s perfect for space where you want to have dimmed and warm toned atmospheric lighting.
How long do COB Lights last?
A COB LED has an average rated lifetime of 50,000 hours.
Does a COB LED need a driver?
LED Drivers
LED drivers are the handy little boxes that take the power from your electrical outlet and convert it to a form that the COBs can use. The electricity coming from your outlet is alternating current (AC), and this does not work for COB LEDs they require direct current (DC) instead.
How efficient are COB lights?
This improvement is said to deliver an energy savings of approximately 11 percent compared to the prior product generation. This series is available in four light-emitting surface (LES) configurations and can operate over a broad current range.
What is the difference between COB and Cree?
The main or the most evident difference between the two is their physical appearance. The SMD Cree led high bay is physically larger and has a wider PCB area than the COB.When in use, both the LEDs produce a lot of heat. This is as a result of the mechanism or technology behind them.
What are COB lights used for?
COB lights are essentially an array of LED chips that are tightly packed together and bonded to a substrate such as silicon carbide. In effect this creates one large LED chip that has excellent uniformity of brightness, thus making it ideal for photographers and filmmakers.
Where are COB LEDs used?
While these devices could be used for higher output general lighting, the primary use for COB LEDs would be as solid-state lighting (SSL) replacements for metal-halide lamps in applications such as high-bay lighting, street lights, and high-output track lights and downlights.
Which is better Cree or COB LED?
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.
Which is better SMD or LED?
One of the biggest improvements is that SMD spotlights offer a higher lumen output for a lower energy consumption making them more powerful and energy efficient than older LED lights. This is because they work on the principle that fewer and larger SMD LEDs produce a greater lumen output.
What does SMD mean in LED lights?
surface mounted diode
SMD means surface mounted diode. This is a better technology than the first generation DIP LEDs. The SMD type LEDs are mounted on an aluminum substrate and enveloped in an epoxy resin.
What are the brightest LED chips?
The UltraBright Series are of the Brightest LED strips in the world! Though 5050 and 3528 SMD LEDs were the most popular on the market for strip lights, the LED market has changed rapidly over the past few years. Today, there are many LED chips available that are brighter and also more efficient.
Do LED lights attract bugs?
LED lights produce little to no UV light and a minuscule amount heat, which makes them less attractive to bugsso long as they emit longer wavelengths of light.
Do COB LEDs need a heatsink?
In the case of COB LEDs, it is possible to directly attach a COB LED to a heat sink (see Figure 2). As a result, COB LEDs do not require PCBs in order to install LEDs into a luminaire and the subsequent reflow process is no longer necessary.
