3528 is introduced:
3528 single lamp bead is 0.06 W, chip size is generally 10 * 16 nm, 18 nm or 10 * 10 * 23 nm now in the market for one of the most common fluorescent lamp brightness in 7-8 lm, some manufacturers in order to reduce the cost of the actual use is likely to be 6-7 lm.
2. Analysis of advantages and disadvantages:
(1) light spot: the thickness of 3528 is 1.8mm, which is mainly light emitting light. It is more likely that the fluorescent lamp will produce the light spot (the PC face is very aluminum and there will be clear spots in the contact of the aluminum shell, and there will be light spots on the wall).
(2) heat dissipation performance: 3528 patch heat dissipation performance is poorer, the bottom of the radiator between the chip and are separated by a layer of plastic, so the cooling performance is poorer, make fluorescent lamp work lamp bead amount and more, so the whole light radiating performance is poor, the life of the led lamps and lanterns is known to all the main influence factor is the temperature, so it is of great harm to the life of the lamp is.
Made fluorescent tube (3) the cost of lamps and lanterns: higher costs and lower photosynthetic efficiency, such as a 20 w led fluorescent lamp USES 3528 to 288, 7-8 LM 3528 is the cost of light source: 288 * 013 yuan / = 37.44 yuan, to make the whole lamp brightness is: 288 * 7.5 LM (middle value) of the single lamp bead brightness (power supply power factor) * 0.85 * 0.9 (the light rate) = 1652.4 LM (the whole lamp brightness around 1600 LM);, of course, if some manufacturer just consider cost without considering quality may use a low low price of the lamp bead, for example, use 288 grains of 6 to 7 LM 3528, cheap price may be 0.06 yuan/grain, so the cost will drop a lot: 288 * 0.06 = 17.28 RMB yuan/grain of grain, but brightness will decline a lot: 288 * 6.5 LM (middle value) of the single lamp bead brightness (power supply power factor) * 0.82 * 0.9 (the light rate) = 1381.5 LM (the whole lamp brightness around 1380 LM)
