First of all, when we choose the patch LED lamp bead, the key is to consider the color temperature, color rendering index, light efficiency, light decay, and the quality of the power supply. Speaking of course, many friends will ask, \"The larger the size of the chip of the same brand under the same current, the higher the brightness is not the smaller the heat ah?\"
This may have become the past, in the current process 2835 patch lamp beads in the process has been small size, good heat dissipation, high brightness while greatly reducing the cost of shaping lamps.
The cost of high-power lamp beads is slightly higher, mainly to do relatively large wattage lamps, and the cost of small power is slightly lower.
