How to choose lamp beads

The 2835 lamp bead is a medium-power chip super bright light-emitting diode, with 0.1W, 0.2W and 0.5W. Because its size is 2.8 (length) × 3.5 (width) × 0.8 (thickness) mm, according to the size of the chip LED lamp bead Naming method, named 2835 lamp beads. The 5050 lamp bead is also a light-emitting diode, the size is 5mm*5mm*1.6mm, the light intensity can reach 5500-6000MCD (pure white light, the warm light is slightly smaller), the working voltage is the same as the ordinary LED, only 3.2-3.4 V, the current is the same, 60MA. These two are also one of the most common SMD LED lamp bead models on the market.

Many friends have wondered, which one is brighter, 5050 lamp beads or 2835 lamp beads? Which is better to use? What's the difference?

In addition to the size difference between the 5050 lamp beads and the 2835 lamp beads we mentioned earlier, the 5050 lamp beads are generally packaged in parallel with three 0.02W chips, the total power is 0.2W, and the brightness is 20-26LM. Of course, more Chips with high bare die brightness can achieve several different files such as 26-28LM/28-30LM/30-32LM/32-34LM.

The 2835 lamp beads are generally packaged in a single chip, with a power of 0.2W, 0.5W and 1W. The same 0.2W chip has the same brightness as the 5050 lamp beads, which can be 20-26LM, or higher bare die can be used. The brightness chip can achieve several different files such as 26-28LM/28-30LM/30-32LM/32-35LM.

Because the thickness of the bracket is thinner than that of 5050, and the single-chip package is used, the light source is relatively concentrated, and because of its small size and more flexible design, it is widely used in lighting LED lighting products, such as fluorescent tubes and bulbs. , ceiling lights, downlights and so on.

The 5050 lamp bead is a patch-type LED with a long history. It is mainly used for LED products such as light strips, guardrail tubes, modules, and luminous characters. Due to the characteristics of 5050 lamp beads, RGB three-color lamp beads can be packaged separately, so 5050 is also a model used to encapsulate 5050 full-color RGB lamp beads.

In short, 5050 lamp beads and 2835 lamp beads are one of the very common and very popular SMD LED lamp beads. Each has its own functional characteristics. Under the same material and the same power, the brightness is basically the same. But they have different strengths and adapt to different application fields. Therefore, it is not simply which one has high brightness and which has better effect, but depends on what your purpose is.
