The feature of the SMD 1ea lamp bead that distinguishes it from other light sources is its controllability, which makes its application range very wide. The use of SMD LED lamp beads with different parameters is very different. Today, Shenzhen Expand Optoelectronics Co., Ltd. You analyze the various parameters of the SMD LED lamp beads, and hope to help you all.
Forward direct current IFm: Allowable positive direct current. Exceeding this value can damage the SMD LED lamp beads.
Reverse voltage VRma allows the reverse voltage to be applied. Generally speaking, the reverse voltage of the SMD LED lamp beads cannot exceed 5V. If this value is exceeded, the SMD LED lamp beads may be damaged by breakdown.
Allowable power consumption Pm: the large value of the product of the positive DC voltage and the current flowing through it. If this value is exceeded, the LED will heat up and be damaged.
Forward working voltage VF: The working voltage of SMD LED lamp beads is generally 1.5-3.6V, and the working voltage of LEDs of different wavelengths may be different. The ideal working voltage of yellow-red LED with longer wavelength is 1.8-2.2V, blue and white light. The ideal working voltage is 2.8-3.2V. The ideal voltage is also related to the temperature,
