Now many friends are very concerned about the voltage of 5mm beads to what extent is normal? The voltage and current of 5mm straw hat beads. So today, Chen Xing Xiaobian will share the information about the normal voltage of 5mm marbles and the voltage and current of 5mm straw hat marbles, hoping to be helpful to everyone.
With the continuous development of science and technology, LED lamp beads are widely used in life. When purchasing LED lamp beads, many people will pay attention to voltage and current. It is worth mentioning that 5mm lamp beads, as the most common LED lamp beads, have attracted much attention. So, what is the normal voltage of 5mm marbles? What about the voltage and current of 5mm straw hat and other beads? This article will introduce these problems in detail.
5mm lamp bead voltage is slightly normal
5mm lamp bead is the most common LED lamp bead. How much is its voltage normal? First of all, we need to know what voltage is. Voltage refers to the difference in power between two ends of the conductor in a circuit, that is, the energy of charge passing through the conductor per unit time. The voltage of LED lamp bead is the voltage value required for the initial brightness of LED lamp bead under positive current.
The voltage of 5mm beads is generally 2.0 V-3. 6V. The specific voltage value depends on the brand, color, brightness and other parameters of LED bulbs. For example, the voltage of red LED beads is 2.0 V-2. 5V, while the voltage of blue LED beads is 3.0 V-3. 6V.
In addition, it should be noted that the voltage value of LED bulb is closely related to the current value. If the current is too large, the voltage value will increase accordingly, which will adversely affect the life of LED bulbs. Therefore, when using LED lamp beads, appropriate current values should be selected according to different parameters to avoid the damage of LED lamp beads.
Voltage and current of 5mm straw hat equal beads
5mm straw hat bead is a commonly used LED lamp bead, and its voltage and current parameters are also what we need to know. Compared with 5mm straw hat beads, the voltage and current parameters of 5mm straw hat beads can be higher.
Generally, the voltage of 5mm straw hat beads is 3.0 V-3. 6V, and the current is 20mA-30mA. These parameters may vary according to brand, color and brightness. For example, the voltage of red 5mm straw hat beads is 1.8 V-2. 2V and the current is 20mA-30mA; The voltage of green 5mm straw hat beads is 3.0 V-3. 6V, and the current is also 20mA-30mA.
It is worth noting that the voltage and current parameters of 5mm straw hat beads should also be selected according to the use scenario. Excessive current will not only affect the life of LED lamp beads, but also lead to overheating, lamp beads burning and other dangerous situations. Therefore, when using 5mm straw hat beads, we should carefully select appropriate current parameters to ensure their normal operation.
Relationship between LED lamp bead life and voltage and current
We should not only know the voltage and current parameters of LED lamp bead, but also know the influence of voltage and current on the life of LED lamp bead. Generally speaking, too high voltage or too high current will adversely affect the life of LED bulbs. Therefore, when using LED lamp beads, appropriate voltage and current values should be selected according to their parameters.
In addition, temperature will also affect the life of LED bulbs. LED lamp beads will generate a certain amount of heat when they work. Excessive temperature will not only affect the bead itself, but also cause the failure of other parts. Therefore, when using LED lamp beads, we should pay attention to the heating problem and ensure normal work.
How to Choose the Appropriate LED Driving Circuit
LED driving circuit is an important link to control the current and voltage of LED bulb. When choosing LED driving circuit, it should be selected according to the parameters of LED bulb, so as to make it work normally.
First of all, the output voltage and current of the driving circuit should be selected according to the voltage and current parameters of LED bulb. Secondly, we should choose the appropriate driving circuit type. At present, the common driving circuit types include constant current driving circuit and constant voltage driving circuit. The constant current driving circuit ensures that the current of the LED lamp bead is not affected by the voltage change, and the constant voltage driving circuit ensures that the brightness of the LED lamp bead is not affected by the current change. Finally, attention should be paid to the quality and stability of the driving circuit to ensure the normal operation of LED bulbs.
Application Scenarios of LED Lamp Beads
With the continuous development of science and technology, LED lamp beads are widely used in life. At present, LED lamp beads have been widely used in lighting, display, communication and other fields.
In the field of lighting, LED lamp beads have replaced traditional incandescent lamps and fluorescent lamps as mainstream lighting products. Compared with traditional lighting products, LED lamp beads have the advantages of energy saving, environmental protection and long service life. In the display field, LED lamp beads are also widely used in a variety of display screens, such as LED TVs, LED screens and so on. In the field of communication, LED lamp beads also have applications in optical communication, such as optical fiber communication.
