3528LED lamp beads are mainly used in: indoor lighting, commercial lighting, industrial lighting. Such as LED lighting products, LED decorative products, LED backlight products, lighting lighting, backlight display (LCD, billboards), automotive lights and other patch lamp products.

3528 lamp beads color parameters

3528 green light voltage 3.0-3.4V luminous intensity 1000-1200 (mcd) luminous flux 3000mlm angle 120°

Low light decay: After the LED works, 20mA will be continuously lit continuously, the brightness will gradually increase to about 1500 hours, the brightness will increase by 12%; 10000 hours, the light decay will be less than 25%.

The maximum current of the patch is 500mA. It can only be instantaneous. The time is less than 2 seconds. Normal 15mA. 20mA lighting does not affect the light decay.

SMD LED is strictly split and the brightness is uniform

High brightness, concentrated color area, large angle, low thermal resistance, ultra low light decay process, long life

  3528 single lamp bead is 0.06W, the general chip size is 10*16nm, 10*18nm or 10*23nm (the larger the chip size, the higher the current can withstand, the higher the brightness). Now it is used for fluorescent lamps on the market. The most common brightness is 7-8LM, and some manufacturers may use 6-7LM in order to reduce the cost.

3528 lamp beads application features

1. The light decay is small. After the LED works, the 20mA normally lights up continuously, the brightness will gradually increase to about 1500 hours, the brightness increases by 12%; 10000 hours, the light decay is less than 25%.

2, the maximum output current of the chip is 40mA, normal 20mA, 30mA lighting does not affect the light decay.

3, high brightness, color area concentration, large angle, bottom thermal resistance, ultra low light decay process, long life

Analysis of the advantages and disadvantages of 3528 lamp beads

(1) Spot: 3528 thickness is 1.8mm, mainly point light, making fluorescent lamps more likely to produce light spots (pc masks have obvious spots on the aluminum shell contact, there are spots on the plug)

(2) Heat dissipation performance: 3528 patch heat dissipation performance is poor, the bottom heat sink and the chip are separated by a layer of plastic, so the heat dissipation performance is poor, and the number of lamp beads used for the fluorescent tube is more, so the heat dissipation performance of the whole lamp It is also poor. Everyone knows that the main factor affecting the life of LED lamps is temperature, so this is a great hazard to the life of the lamp.
