3528 SMD lamp bead features:

Voltage: SMD LED lamp beads use low voltage power supply, the power supply voltage is between 2-4V, depending on the product, so it is driven by a higher voltage than the high voltage power supply; it is especially suitable for public places;

Current: The operating current is between 0 and 15 mA, and the brightness becomes brighter as the current increases.

Performance: Energy consumption is reduced by 80% compared to incandescent lamps with the same efficacy.

Applicability: Very small, each unit LED chip is 3-5mm square, so it can be made into various shapes and suitable for a variable environment.

Response time: The response time of its incandescent lamp is milliseconds, and the response time of the LED light is nanosecond.

Environmental pollution: no harmful metal mercury.

Color: Change the current to change color. SMD LED lamp beads can be easily adjusted by chemical modification method to adjust the band structure and band gap of the material to realize multi-color luminescence of red, yellow, green and blue. For example, a red LED with a small current can turn orange, yellow, and finally green as the current increases.
