Learn more about 5 mm lamp beads

5mm Now many friends are concerned about what is 5mmLED lamp bead and what is the working current of 5mmLED lamp bead. Today, I compiled the information about what is 5mmLED lamp bead and what is the working current of 5mmLED lamp bead, hoping to help everyone.

With the development of technology, LED lamp beads have been widely used in lighting, display, car lights and other fields. As a common specification, what is the working current of 5mm LED bulb? This paper will elaborate on this problem from many aspects.

First: What is a 5mm LED lamp bead?

5mm LED bulb is a semiconductor device that emits light through solid-state electronic devices, which is usually composed of LED chip, PCB substrate and two pins. Among them, the chip is made of semiconductor material. When passing through the chip, electrons meet holes to generate energy and emit light. The function of PCB substrate is to fix and conduct current, and pins are used to connect with other circuits.

The advantages of 5mm LED bulb include low power consumption, long life, high brightness, anti-vibration, anti-electromagnetic interference and so on. Therefore, it is widely used in lighting, display, car lights, electronic products and other fields.

Second: What is the working current of 5mm LED bulb?

The working current of 5mm LED bulb refers to the normal luminous current. Under normal circumstances, the working current of 5mm LED beads is about 20mA. However, different chip materials and manufacturing processes will lead to different working currents.

In addition, the brightness of 5mm LED beads is also related to the working current. Generally speaking, with the increase of working current, the brightness will increase correspondingly, but at the same time, the life will also decrease. Therefore, in practical application, reasonable current setting should be carried out according to specific conditions.

Third: What are the colors of 5mm LED bulbs?

There are many colors of 5mm LED lamp beads, such as red, yellow, green, blue and white. The luminous principle of these colors is based on different materials and processes.

For example, red LED beads use aluminum nitride and yellow phosphorus powder, green LED beads use aluminum nitride and cadmium, and blue LED beads use gallium nitride and germanium. In addition, there is an LED lamp bead, which mixes various materials and emits white light.

Fourth: How to choose 5mm LED beads?

When selecting 5mm LED beads, the following factors need to be considered:

1. Brightness: Select the appropriate brightness level according to the specific application.

2. Color: Choose the appropriate color as needed.

3. Working current: set according to specific chip requirements.

4. Luminous angle: Different luminous angles will affect the lighting effect, so the appropriate angle should be selected according to the needs.

5. Environmental requirements: The temperature, humidity, anti-vibration and anti-electromagnetic interference of the working environment should be considered.

Fifth: the future development trend of 5mm LED lamp beads.

With the continuous progress of science and technology, 5mm LED lamp beads will be more and more widely used in lighting, automobile, electronic products and other fields. The future development trend of 5mm LED lamp beads is as follows:

1. High brightness: With the continuous improvement of technology, the brightness of 5mm LED beads will be higher and higher.

2. Multi-function: 5mmLED lamp bead will integrate sensors, communication and other functions.

3. Energy saving and environmental protection: 5mmLED lamp beads are more energy saving and environmental protection, and will become the mainstream of lighting field in the future.

4. Intelligentization: 5mm LED lamp beads will realize more intelligent control, such as controlling light brightness and color through mobile APP.

5. Production automation: 5mm LED lamp beads will realize more automatic production, reduce production costs and improve production efficiency.
