Many friends are asking what does 2835 and 5050 mean? In fact, LEDchip is named according to the size of the chip. The reason why it is called 2835 is that the LED chip is 2.8mm long and 3.5mm wide. But there is a special situation. Do you know the difference between 2835 and 3528? This article takes you to find out from 4 aspects.
1. In terms of brightness
The traditional 3528 led chip is generally bright as a single 5.5 lumens, and the highlight is 6.5 lumens. Now the 2835 patch is expanded to 11 lumens and the highlight can reach 19 lumens (A series). It is obvious from the data that 2835 stickers The overall brightness of the LED chip is at least 1.5 times higher than that of the 3528 lamp bead series.
(Note: The chip size of the wick determines the brightness of the lamp. The 3528led chip can reach up to 10*16 and the chip size of the 2835 chip can reach 11*28. The high-brightness 2835 chip can be completely compatible with The brightness of 5050 patches on the market is comparable)
2. From the perspective of light emission
The traditional 3528 lamp bead has a beam angle of 120°, while the beam angle of the 2835 SMD wick is from a single 11-lumen wick to a single high-brightness wick with 19 lumens, and its luminous angle gradually increases from 135° to 150° to 165°.
3. From the perspective of package size.
2835 led chips are packaged in 2.8*3.5*0.7MM, and 3528 led chips are used in 3.5*2.8*1.9MM package, the biggest difference is that the height of the 3528 led chip is 1.9MM, while the height of 2835 led chip is 0.6-0.8MM.
4. From the aspect of appearance:
From the aspect of appearance: the light-emitting surface of the 3528 LED chip is round, while the light-emitting surface of the 2835 led chip is square with rounded corners.
5. From the aspect of heat dissipation
The 2835 led chip has a heat sink design, so it can withstand greater power. While the 3528 led has no heat sink design, 3528 is generally used to produce a 0.06W led chip with a maximum power of 0.1W, while 2835 led chips are mainly used to produce 0.2W and 0.5W led chip, and the maximum can be used to produce 1W (PCT bracket), 3W (EMC bracket) led chip, this is the biggest difference between 3528 led chip and 2835 led chip.
We made a table so that you can understand their differences more clearly：
Light Source Appearance
Square with Rounded Corners
1. Better heat dissipation performance.
The heat of the chip is directly exported from the bottom of the bracket, which has a larger heat dissipation area than the 3014 and 3528.
2. The light-emitting surface is rectangular and larger.
Compared with 3014 and 3528, the light-emitting area is large, the light-emitting angle is large, and the light is uniform. The light-emitting area is 2.3 times that of 3014 and 2.1 times that of 3528.
3. With a wide range of applications.
2835 is an upgraded new light source, it overcomes the shortcomings of 3014's small side beam angle and effectively solves the point light source phenomenon in 3528 lighting applications.
4. Wide range of current used.
According to the product model and customer's heat dissipation conditions, it can be used with a variety of currents of 20-50 mA.
5. Replace 5050.
The use of special specifications can effectively replace 5050.
1. The amount of silica gel used is 1.4 times that of the existing 3528 glue, and the amount of phosphor is 1.7 times.
2. The bracket needs a large silver-plated area and consumes a lot of silver. The bracket thickness is 0.3mm, which is twice the thickness of the existing 3528, which is 0.15mm.
