The disadvantage of this system is the low intensity of the light.
The most popular light source of LED lamps. The types of SMD LED Modules are distinguished by the dimensions of the LED chips.
Common types are 5050 SMD LED, 3528 SMD LED, 2835 SMD LED.

This is a new LEDs technology that eliminates the drawbacks of its predecessors - heat dissipation is appropriate, light is clear, and thanks to the thin protective layer, the bulbs are healthy for the eyes.
This technology allows you to place a plurality of LEDs together as a single lighting module.
During the lighting looks like a panel lighting, the whole surface of the LED is full, there are no visible gaps as in DIP or SMD LEDs.
Contact us to discuss your requirements of smd led pcb board. Our experienced sales team can help you identify the options that best suit your needs.
COB surpasses traditional lighting up to 50 times in terms of light output per centimetre of the surface illuminated.
This provides significant advantages compared to traditional lighting.
All these numbers! What's going on?
Have you ever been looking for LED light strips and ran across the numbers 2835, 3825, or 5050?
These numbers are less mysterious than you might think.
First off, you might have seen the letters "SMD" preceding these enigmatic numbers. The abbreviation SMD refers to a 'Surface Mounted Device'. That means this is an LED Chip (device) mounted directly to a light strip, without using wires. This surface mounting technology is indeed what makes LED Light Strips possible. The numbers after the SMD simply refer to the physical size of the LED Chip. Take SMD 3528 for example, they are 3.5mm wide and 2.8mm long. Note that size is not proportional to output or performance, and it is not the only difference between LED chip types.
SMD 3528 Chips are perhaps the most common of all LED light strip chips. They are the least bright and least power-intensive of the three chips we use at HitLights, and are most commonly used for accent lighting, such as above kitchen cabinets and around the crown molding below the ceiling.
3528 chips used to be featured in our Luma5 strips, but those now primarily use lower output 2835 chips which offer the same brightness of 3528 chips but with greatly improved efficiency and lifespan. You can shop our selection of Luma5 strips here.
SMD 5050 Chips are just barely behind the 3528 chips in popularity. These chips are 5.0mm x 5.0mm. 5050 chips are typically 3 times as bright as 3528 chips. Because they're brighter, strips with 5050 chips are typically used for what we call 'task lighting', and commonly used underneath kitchen cabinets where that light will help you see what you're working on. 5050 strips are often also available in color changing styles, meaning that you can select any color you want with a remote or controller.
5050 chips used to be featured in our Luma10 strips, in both the single color and multicolor versions. You can shop our selection of Luma10 RGB 5050 kits here.
SMD 2835 Chips look very much like 3528 chips, but they use newer technology and are typically much more efficient. This means that for equivalent power, they can be much, much brighter. They're smaller than the 5050 chips (2.8mm x 3.5mm). They make the ultimate in task lighting and even work lighting.
High output 2835 chips are utilized in our Luma20 strips, which are the brightest (and most efficient) strips that we sell. You can shop our selection of Luma20 strips

Editor's note: As a final aside, while the Luma designations initially were associated with certain chip types (Luma5 was 3528, Luma10 was 5050, and Luma20 was 2835) with improvements in LED technology these designations quickly became invalid. Instead, our Luma designations should always refer to the number of lumens per chip - around 5 lumens per chip for Luma5, around 10 lumens per chip for Luma10, and around 20 lumens per chip for Luma20.
Now you should know the difference between the different types of LED chips on our strips.
