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 chips also only have 1 circuit and 2 contacts, regardless of the number of the diodes. … COB is known for better lumen-per-watt ratios and heat efficiency.
What is a COB LED?
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.
Do COB LEDs need drivers?
3. 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.
What is COB mode?
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. COB LEDs have a number of advantages over older LED technologies, such as Surface Mounted Device (“SMD”) LEDs or Dual In-line Package (“DIP”) LEDs.
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.
Which is better Cree or COB LED?
The CREE LED lighting system has a larger size and a PCB area that is wider than its COB counterpart. Both of the LEDs generate large quantities of heat when they are both being used. … By being wider and bigger, CREE can dissipate a higher volume of heat into its environment. This simply means that it is longer-lasting.
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).
Do COB LED need heatsink?
The abbreviation COB refers to Chip On Board. … 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.
Are COB LED lights 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.
Why do LEDs need drivers?
Why Do I Need an LED Driver? … An LED driver’s main purpose is to rectify higher voltage, alternating current to low voltage, direct current. LED drivers also protect LEDs from voltage or current fluctuations. A change in voltage could cause a change in the current being supplied to the LEDs.
What does SMD mean for LED lights?
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 SMD LEDs?
SMD LED. SMD stands for Surface Mounted Devices, a special type of high power LED lights. With no wires, these devices provide less fuss and with seamless application. Instead, SMDs have tiny metallic contacts that can be directly soldered to circuit boards.
What is the brightest type of LED?
What is the brightest LED type? Yes, as you can see by the table above, 5630 LEDs are by far the brightest, but it is not due simply to a larger lighting surface. There are other factors that go into the output of an LED diode (measured in luminous flux/lumens).
What is the best SMD LED?
What is the Best SMD Chip?
- 3528 SMD CHIP. The 3.5mm x 2.8mm chip is one of the most popular, due to its cost effectiveness and the fact that it doesn’t give off much heat. …
- 5050 SMD CHIP. 5.0mm x 5.0mm are known as having ‘tri-chips’ simply meaning that they have 3 LED diodes in one housing. …
- 2835 SMD CHIP. …
- 5630 SMD CHIP.

Why do LED lights burn out quickly?
Unlike incandescent light bulbs, LEDs don’t produce light using heat. This is part of what makes them so energy efficient. The downside is that their components can be sensitive to overheating, which can cause them to burn out prematurely.
