The 2835 single lamp bead has 0.12 W 14-16lm (the chip size is 10 * 23nm), with 0.2w 22-24lm (the chip size is 10 * 30nm), both of which are suitable for sunlight.
2. Analysis of advantages and disadvantages:
(1) 2835 lights use vertical encapsulation structure: chip conduction heat sink directly, and the heat sink area was more than twice the 3014 or so, to further improve the performance of radiator lamp bead itself, which can take more current (40-60 ma), higher brightness, good heat dissipation performance design, also droop of the LED chip and a more secure life;
(2) ultrathin structure: 2835 thickness is also 0.8mm, which can solve the spot problem of 3528.Large luminescent surface (square luminous surface) : can increase the light rate: up to 90%.
(3) cost: or 20 W, for example:
1, if you choose to use 0.12 W 14-16 lm 2835, the 20 W fluorescent lamp need 144 grain of lamp bead, light cost is: 144 * 0.17 = 24.48 RMB yuan/grain, make whole lamp brightness is: 144 * 15 lm (middle value) of the single lamp bead brightness (power supply power factor) * 0.9 * 0.9 (the light rate) = 1749 lm (the whole lamp brightness around 1749 lm).2, 1, if you choose to use 0.2 W 22-24 2835 lm, the 20 W fluorescent lamp need 100 grain of lamp bead, light cost is: 100 * 0.19 yuan / = 19 yuan, make the whole lamp brightness is: 100 * 22 lm (middle value) of the single lamp bead brightness (power supply power factor) * 0.9 * 0.9 (the light rate) = 1782 lm (the whole lamp brightness around 1782 lm).
