LED chip electrode map: If the chip manufacturer is different, the quality of the LED will be different. The LED manufacturer will clarify which brand of chip package their LED SMD lamp beads use. After the white light LED package, it is impossible to judge the chip from the appearance. Manufacturer's, unless the peeled chip is examined under a high-power microscope.

Finally, let's take a look at the relevant parameters of 3528 LED lamp beads. 3528 emits white light: warm white temperature: 2800-3200k, positive white light (cold white temperature): 6000-9000K-15000K or more.

3528 emits red light: conventional wavelength: 620-630nm, voltage: 1.9-2.2V, power 0.06w, current: 20mA.

3528 emits orange light: conventional wavelength: 600-610nm, voltage: 1.9-2.2V, power 0.06w, current: 20mA.

3528 emits yellow light: conventional wavelength: 585-595nm, voltage: 1.9-2.2V, power 0.06w, current: 20mA.

3528 Emerald Green: Regular wavelength: 515-525nm, voltage: 3.0-3.3V, power 0.06w, current: 20mA.

3528 yellow-green: conventional wavelength: 565-575nm, voltage: 1.9-2.2V, power 0.06w, current: 20mA.

3528 emits blue light: conventional wavelength: 460-470nm, voltage: 3.0-3.3V, power 0.06w, current: 20mA.

3528 emits violet light: conventional wavelength: 395-410nm, voltage: 3.0-3.3V, power 0.06w, current: 20mA.

3528 is pink: Voltage: 3.0-3.3V, power 0.06w, current: 20mA. (See specifications for other detailed parameters).
