Surface-mounted LED chips, or SMD, on a printed circuit board are known as "surface-mount devices" (printed circuit board). It is because they are manufactured utilizing surface mount technology (SMT). This method is preferred because it is more practical and can be easily installed on tiny gadgets.
The previous method of assembly, which relied on wire leads, was eventually rendered obsolete by this new method. This technology can be packed in even more electronics into a relatively small area. PCBs can be assembled and soldered automatically with the help of this technology.
The manufacturing process utilized to create these bulbs and filaments is transferable to many other lighting applications. In addition, your phone's notification light is likewise an SMD LED. After your phone alerts you to something, the light you see is an SMD light.
SMD LEDs are one of the most popular lighting options available. They're put to good use in various outdoor settings because of their high efficiency and ability to produce sufficient light. But there are still more reasons to use these bulbs.
"Chip on board" (COB) refers to an LED chip mounted directly onto a substrate, such as silicon carbide or sapphire. The chips are stacked close to one another. A COB consists of at least 9 diodes, 1 circuit, and 2 contacts on a printed circuit board.
As part of its COB technology, the use of printed circuit boards and COB chips allows for the development of dependable, energy-saving lighting devices. You'll find the printed circuit board (PCB) in aluminum or ceramic COB substrate.
Depending on the board, the COB chips will be arranged in a series or a parallel pattern on the PCB.
A variety of substrate materials are used to optimize LED performance. For instance, the ceramic material's thermal conductive performance guarantees the correct temperature is maintained for the LED bulbs, allowing them to function optimally.
In addition, depending on the PCB, the chips in this kind of illumination can be stacked in parallel or a specific sequence. These bulbs take on the appearance of panels because of this.
Typically, an aluminum heat sink is used in COB bulbs. The heat sink can dissipate the light source's waste heat.
Street lighting, playground lighting, light strip lighting, downlights, landscape lighting, and high bay lighting are examples of the many places you can find COB LED lights in use. The question then becomes why exactly these particular LED lights are so popular.
Superior lighting results
COB lights create brighter, higher-quality light and have a more significant impact on the surrounding environment. Because of how the chips are designed, more of them may be used to produce consistent, glare-free illumination.
Greater thermal efficiency and lumens-per-watt ratio
Because of their construction, COB lights are more heat efficient and produce more light for their power consumption. They can produce lumens above 80 while consuming less power.
Improved heat transfer
COB LEDs feature a substantial cooling area and a few individual parts. The circuit board is in sight of the COB's heat sink. In addition, the COB LED's efficient heat dissipation can be attributed to the substrate material, board circuit, and heat sink components.
Because of their commonalities, SMD and COB lights have become two of the most widely used bulbs. Several of them are as follows:
LED lights are quickly replacing incandescent filament bulbs as the industry standard. These two lights have similarities, but some key distinctions set them apart. The details below illustrate some of the more noticeable distinctions between them.
The efficiency, brightness, cost-effectiveness, and utility of a given light source are only a few variables that should inform your choice of lighting.
These lights are efficient in their energy use while being dependable and producing a lot of light. For instance, COB is your best bet for increasing light output because it offers a wide lumen output range, typically 80 or more lumens per watt.
SMD lights may be ideal in the bathroom, kitchen, and other rooms where diverse color temperatures are needed.
COB lights can be used for various purposes, including standard streetlights, industrial illumination, high bay lighting, and more.
SMD lights can be adjusted in color and temperature, they are ideal for use in commercial settings like bars and shops.
On the other hand, COB is particularly useful in the safety and manufacturing fields. This is primarily because of how bright and far their beam goes.
With this illumination, you can see further away than before. As you try out the various programs, you can determine which ones suit your needs best. Many other fields could benefit from employing these LEDs as well.
Better beam angles and more aesthetically pleasing fixtures are two benefits that more complex architectural lighting applications can reap from using COB chips. SMD LEDs, on the other hand, are used in diffused panel lights and other types of general illumination where the light source is hidden behind a frosted diffuser.
Commonly used in LED video lights for photography are compact fluorescent light bulbs (CFL) designs. Given their wide beam angle, it's no surprise that photographers and filmmakers favor COB lights for their uniform illumination.
