When high-power white LEDs are used as new green lighting, they will have advantages such as high light conversion efficiency, low power consumption, long life, and no maintenance, so they are gradually applied to various lighting fields. The long life of LEDs is based on their safe working environment. For LED lighting, there are two main threats affecting its life; one is over-current shock, where the over-current shock is that the current applied to the LED exceeds the maximum rated current in the LED technical data sheet, including overvoltage. Overcurrent shock; the other is overheating damage. These damages can be manifested as immediate failure of the component, or it can occur long after the over-current shock event, shortening the LED operating life.
LED lamp damage
The failure of LED luminaires is due to the failure of the power supply and drive, and the failure of the LED components themselves. Often the damage to the LED power supply and drive comes from the over-current surge (EOS) of the input supply and the open-circuit fault at the load. The over-current shock of the input power supply often causes damage to the driver chip in the drive circuit and breakdown of the passive components such as capacitors. The short-circuit fault at the load end may cause over-current drive of the drive circuit, and the drive circuit may be damaged by short-circuit or Overheating damage caused by short circuit faults.
The failure of the LED component itself
Transient overcurrent event
Transient overcurrent event means that the current flowing through the LED exceeds the maximum rated current in the LED technical data sheet. This may be due to the direct generation of large current or indirect high voltage, such as transient lightning strikes, switching. Transient switching noise of the power supply, overcurrent caused by overvoltage events such as grid fluctuations. These events are transient and have a very short duration. Usually we call them spikes such as "current spikes" and "voltage spikes." Conditions that cause transient overcurrent events include transient overcurrents when the LED is powered up or plugged in.
For LED lighting in cars, the transient load dump surge of ISO7637-2 is an important threat to its normal operation.
The failure mode of an LED after an electrical shock is not fixed, but it usually causes damage to the weld line, as shown in Figure 1. This damage is usually caused by extreme transient overcurrents, which can cause damage to other parts of the weld line, such as sealing materials, in addition to causing the weld line to blow.
For esports headsets, USB jack is used, the traditional 3.5mm headphone jack design does not appear acoustic positioning sense, pay more attention to surround sound, design field is different. Wired Game Headphones definitely have lower latency than Wireless Gaming Headphone for Gaming Headphones. Usually use magnetic ring shielding, tensile line design.
Common esports headsets use an all-inclusive design,which has the advantage of isolating ambient noise.The headband part of the earphone will be different from each type of earphone.The strength of the headband will determine whether it will compress the head after wearing, whether it is breathable and other details.
Common esports headphones will be equipped with switch adjustment. When choosing, you can give priority to products that support 7.1 sound channel, consider supporting light switching, and consider supporting acoustic positioning function. Usually tap earphones will also come with a microphone design. Consider models with high sensitivity and acoustic noise reduction.
The online esports headphones are mainly USB ports, and the independent sound card design is mainly used to create virtual sound effects and positioning effects. The use of esports headphones will inevitably appear cool light effect, headset light, microphone light, RGB light belong to the current mainstream design.
