Piranha LED beads, as a widely used LED bead in lighting, automotive indicator lights, backlit light boxes and other fields, have important parameters that determine their performance and application range, such as rated voltage and rated current. This article will delve into the rated voltage and rated current of piranha lamp beads, including their definition, range, influencing factors, and precautions in practical applications.

1、 Definition of Rated Voltage and Rated Current

Rated voltage refers to the maximum voltage that LED chips can withstand under normal operating conditions. Exceeding this value may result in damage or performance degradation of the chips. For piranha light beads, their rated voltage range varies depending on the color. Generally speaking, the rated voltage of white, blue, green, and purple light piranha beads is between 3.0-3.2V, while the rated voltage of red, yellow, and orange light piranha beads is lower, usually between 2.0-2.2V. In addition, the rated voltage of the infrared emitting (850NM) and receiving (940NM) piranha light beads is lower, at 1.3-1.5V.

Rated current refers to the maximum current value at which an LED bulb can operate stably at rated voltage. The rated current directly affects the brightness, heat generation, and service life of LED chips. For piranha bulbs, their rated current is usually between 20mA and 60mA, and some high-performance or special-purpose bulbs may reach higher current values, such as 70-80mA. However, it should be noted that although piranha bulbs can withstand higher currents, long-term operation under conditions close to or exceeding the rated current will accelerate their aging and shorten their service life.

2、 Factors affecting rated voltage and rated current

The rated voltage and rated current of piranha lamp beads are influenced by various factors, including but not limited to the following:

1. Materials: The chip material, packaging material, and electrode material of LED beads will all have an impact on their rated voltage and rated current. For example, chips made from high-purity silicon materials can withstand higher voltages and currents.

2. Packaging process: The quality of the packaging process directly affects the heat dissipation and electrical performance of LED chips. A good packaging process can reduce the temperature rise of the lamp beads, thereby increasing their rated voltage and current.

3. Working environment: The working environment temperature, humidity, and heat dissipation conditions of LED chips can also affect their rated voltage and current. In high temperature environments, the rated voltage and rated current of LED chips will correspondingly decrease.

4. Service life: As the usage time increases, the performance of LED chips will gradually decline, including the ability to withstand rated voltage and rated current. Aging LED chips may require a reduction in operating voltage and current to maintain stable performance and a longer lifespan.

3、 Precautions in practical applications

In practical applications, it is crucial to correctly select and set the rated voltage and current of the piranha bulb. Here are some key precautions:

1. Matching power supply: Ensure that the power supply used can provide stable voltage and current, matching the rated voltage and current of the piranha bulb. Avoid using excessively high or low voltage and current to prevent damage to the lamp beads or affect their performance.

2. Heat dissipation design: As LED chips generate heat during operation, good heat dissipation design is crucial for maintaining their rated voltage and current. Reasonably design the heat dissipation structure to ensure timely heat dissipation of the lamp beads and avoid performance degradation caused by high temperature.

3. Environmental adaptability: When choosing piranha light bulbs, it is necessary to consider their working environment. For harsh environments such as high temperature and humidity, it is necessary to choose lamp beads with higher rated voltage and current capacity, and take corresponding protective measures.

4. Aging monitoring: Regularly monitor the aging of LED chips, promptly detect any performance degradation, and take corresponding maintenance measures. By adjusting the working voltage and current, the service life of the lamp beads can be extended to ensure their stable operation.

In summary, the rated voltage and rated current of piranha bulbs are important parameters for their performance and application range. In practical applications, these factors need to be fully considered to ensure the stable operation and long-term effectiveness of LED chips.
