High reliability LED display design requirements
With the development of LED display technology, customers have deepened their recognition, and new customers are increasingly demanding the stability and reliability of LED displays. Therefore, in order to meet the requirements, manufacturers must design a more reliable LED display.
At present, China's LED display industry standard "LED display general specification SJ/T11141", in this industry standard and "electronic measuring instrument 2S reliability test GBll463" on the LED display reliability test, in fact difficult to achieve The reliability requirement of MTBF is not less than 10,000 hours, and it cannot meet the requirements of high reliability LED display. In order to achieve high reliability of the LED display, the supporting product materials must be greatly improved, the metering requirements must include heat, reasonable and advanced.
First, supporting product materials
1, LED lighting tube.
LED lighting tube is the key component of LED electronic display, and should adopt the mature and reliable LED products . Features:
Good stability and small dispersion.
High ESD index: HBM is greater than 4000V.
Small attenuation: less than 5% in 1000 hours
Strong pressure resistance: Vr=10V, Ir<2uA
Brightness, wavelength, and angle consistency are high.
Good light distribution: perfect light distribution curve.
It is resistant to temperature, humidity and UV rays and is suitable for outdoor environments.
2, the box.
The whole steel plate or aluminum is used, and the door opening structure is adopted. The top of the box is made of pins and the bottom is made of guide sleeves to ensure precise positioning between the boxes.
The overall protection of the cabinet complies with the IP66 standard. The structure should fully consider heat dissipation.
In-ear earphones, also known as ear canal earphones, are used inside the human hearing organs and, according to their design, sealing the user's ear canal. In-ear earphone is inserted into the ear canal with a gel plug, to obtain better airtightness, on the basis of the ordinary earphone, which greatly increasing the performance of in-ear earphone.
Advantages:
1: Reduce the interference of external noise on music.
2: Provide a closed environment that greatly reduces leakage. From a practical point of view - in a noisy environment,you can enjoy music with a relatively low volume.
3:Increase the low frequency texture and volume.
4:Adding to the performance of the music details.
The catheter of these headphones are connected to the earmuffs into the front half of the ear canal to create a sealed listening environment. And many high-end in-ear earphones even custom-made eardrums for the best comfort and perfect sound insulation.
