COB lamp bead is a kind of LED, also known as COB integrated light source, the small power chip is directly packaged on the aluminum substrate to quickly dissipate heat, the chip area is small, the heat dissipation efficiency is high, and the driving power is small, so it has low thermal resistance and high thermal conductivity. High heat dissipation, compared with ordinary SMD low-power light source features: higher brightness, small thermal resistance (<6°C/W), smaller light attenuation, higher CRI, perfect light spot, long life, LED only for COB light source Packages are: 2835, 3030, 3528, 4040, 5050, 5060, 5730, 7020, etc. The commonly used ones are:
1. 3014 is a low-power lamp bead, each piece is only 0.1W, and the current used is 30MA. Because the bottom is used for heat dissipation, the current is larger than the traditional low-power lamp
2. The 3030 model is a high-power lamp bead, with a power of 1W per piece. It uses a current of 300-350MA, so it consumes more power.
3. The 2835 model is also a low-power lamp bead, some are only 0.1W, and some are 0.2W. The current is 30MA and 60MA respectively. Its bottom heat dissipation area is larger than that of the 3014, so the current can also be larger. Forward The voltage is generally around 2.6-3.8V, and the light-emitting surface of the 2835 lamp bead is generally square and rounded.
4. The 3528 model is also a low-power lamp bead, each piece only needs 0.06W, and the operating current is also within 20MA
5. The 5050 model is also a low-power lamp bead, each chip only needs 0.18W, and the current used is also within 60MA. There are three chips inside, so the current is three times that of the traditional one.
6. The 5730 model is a high-power structure, each 0.5W, and the current is 100-150MA. This kind of light-emitting surface is rectangular. Many round lights like to use this kind of light that spreads over the substrate. corresponding luminous intensity.
