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.
3. Switching power supply.
The display power supply adopts the well-known brand switching power supply module that has passed the certification. All switching power supplies have undergone rigorous testing, screening and aging. Ensure full compliance with international safety and quality certification requirements to meet the long-term stability and reliability of the display. Under rated working conditions. Ensure that the service life is greater than 10 years.
4, the connector.
Connectors are important connecting devices in the system. High quality connector products should be used to ensure the thickness of the pure gold plating of the connector and maintain the best electrical connection performance. To ensure good electrical connection performance of the system in high temperature and high humidity environment,
It can make the system run stably and reliably for a long time.
We offer various small type components for FTTH installation such as braching clip, bare fiber protection tubing, ftth drop cable protection tubes and boxes and so on. The branching clip is used to branch fiber cables. And we have many other fiber optic accessories such as thermo tube, fiber optic protective sleeve, fiber optic splice tray and holder for fiber protective sleeves. ftth drop cable protection tubes, also known as optical fiber protection tube, bare fiber protective tube made of low density polyethylene (LDPE) direct extrusion molding, mainly used for optical cable connector box, optical distribution frame, optical fiber segment and junction box bare fiber maintenance exposed peel. Can be used to maintain bare fiber without damage, not easy to damage. Branch off clip is casted by aluminum and coated by high temperature adhesive, molded by EVA and PA hot melt. This product is used for jointing with cables. This divided into two or three branches up to good breaking up.
