Do You Know The SMD Led Chip?

/in /by

The SMD chips, or “Surface Mounted Device” chips, have become very popular due to their versatility. SMD LEDs have been used to create everything from light bulbs to strip lights, and even missed call indicators on cell phones. These chips are much smaller in comparison to the DIP technology, which tends to give them the added versatility over DIP diodes. SMD technology also supports chips with more complicated designs, such as SMD 5050 chips (depicted to the left), that have RGB capabilities on a single chip. This is very powerful for color combinations, as opposed to the DIP technology, which can only display one color per device. The technology does not take the bullet shaped design from DIP LEDs, and is closer to that of a flat, square computer chip. It is also worth noting that SMD chips can have more than just two contacts (one anode and one cathode). SMD chips can have 2, 4 or 6 contacts, depending on the number of diodes on the chip. With the SMD design, there is an individual circuit for each diode. For example, SMD 5050 chips have 3 diodes on the chip, which translates to 3 circuits and a total of 6 contacts.

SMD chips have been a very important development for the LED industry because of the ability to put 3 diodes on the same chip. When a chip includes a red, green, and blue diode, you have a chip that can create any color you want by adjusting the level of output from each individual diode on the chip. Because they are very bright and can change colors, these chips are used extensively for LED strip lights and light bulbs. SMD LED chips come in a wide variety of sizes, the most common of which are SMD 3528 and SMD 5050S. SMD 3528 chips are only 3.5mm wide, and SMD 5050 chips are 5 mm wide. SMD LEDs can also be made much smaller than the 3528 and 5050 chips. Some of these chips are made very small, to go in high end electronics such as cell phones and laptop computers as indicator lights. Any cell phone you see that has a little light that stays on after the screen turns off is powered by a small SMD LED.

SMD chips that we see in light bulbs and strip lights will typically produce between 4 to 5 lumens per diode on a chip (such as a 3528, single diode chip). These chips will typically run at either 12v or 24v, with 12v being the most common. Individually these chips can pull between 0.05w to 0.08w (single diode, 3528) up to between 0.15w to .24w (three diode, 5050). This means these chips can produce between 50 and 100 lumens per watt depending on the particular chip.

What Are The Difference Between SMD3528 And SMD5050 Led Chip?

/in /by

You’re not the first to ask! As our 2 most popular LED lighting options, customers are often curious as to the similarities and differences between 3528 and 5050 LED light strips. In this article you’ll find some basic knowledge to ensure that you make the right choice when deciding on the strip for your project. It should be noted that these technologies are constantly changing, with efficiency and brightness steadily increasing. The wattages, brightness, etc. in this article are approximations based on the current LED light strips sold by HitLights.

3528smd led chip
3528 LED light strips are named after the dimensions of each chip: 3.5×2.8mm. The small size of 3528 chips is important, because it allows the chips to be placed very closely together on LED strips to create a smoother lighting effect in comparison to a 5050 LED strip. Each chip contains one light-emitting diode, and uses about .08 Watts to produce roughly 4 lumens. 3528’s are great for accent lighting and decorations, but typically aren’t used as a primary light source. They are commonly used in indoor home applications such as stair lighting, under-cabinet lighting, media lighting, and more! Since each chip only contains 1 light-emitting diode, 3528’s are single-color light strips. Our 3528 LED Light Strips are available in Cool White, Warm White, Red, Green, and Blue.

More bang for your buck: 3528 LED’s are our most affordable LED strip solution, and still provide professional quality lighting to any project, business, or home application!

5050smd led chip

5050 LED light strips are also named after the dimensions of each chip: 5.0×5.0mm. The larger chip size of 5050’s mean that they’re spaced farther apart than 3528’s, but actually produce more light per chip. Each chip contains 3 light-emitting diodes, and uses approximately .24 Watts to produce about 12 lumens. Because 5050’s include 3 light-emitting diodes, they can come in single or multi colored strip lights. A single-colored 5050 chip includes 3 diodes of the same color to give more light than a comparable 3528 strip. Alternatively, a multi-colored 5050 chip includes 1 red, 1 blue, and 1 green diode. The brightness of individual diodes on a single chip can then be adjusted to produce any color on the spectrum! Multicolored 5050 LED strips require the use of an RGB LED controller; whereas single-colored LED lights can be connected directly to a DC power source. As our brighter LED strips, 5050’s are great for more luminous accent lighting, task lighting, sign lighting, and can even be used as the primary light source in some cases.

Show Stoppers: 5050 LED Light Strips are our brightest LED strip solution, and provide extremely versatile color-changing capabilities! 5050’s are great for attracting attention to a business, illuminating a party area, lighting up your car or motorcycle, and much more!

Hopefully this post has made your decision between 3528’s and 5050’s a clear choice, so you can get to what matters: your LED project! Need to get inspired?
