1.LED lights and chips
Huicong network security LED lights not only is an LED luminous tube, it is full color LED electronic display of key devices so to the reliable quality, mature package of LED products. Selection of such products must have good stability, small discrete, HBM more than 4000V, attenuation of small amplitude, strong pressure resistance capability, brightness and wavelength, consistent point of view high, light distribution effect good and can withstand temperature, humidity and ultraviolet radiation.
2 Box
Overall use of steel or aluminum, the door structure. The top of the box at the bottom of the guide sleeve and the pin box, ensure the precise positioning. The overall protection of the box is in accordance with the IP65 standard, and the structure should fully consider the heat dissipation problem.
3 switching power supply
The power supply of the display screen is regulated by the famous brand switch voltage stabilized power supply module, all of the switching power supply has been tested strictly, screened and aging. Ensure complete compliance with international safety and quality certification requirements, in order to meet the requirements of long-term stable and reliable display. Under rated operating conditions. To ensure the service life of more than 10 years.
The 4 connector
Connector is an important device in the system connection. Should use the high quality connector products, to ensure that the gold plating thickness of the connector, maintain the best performance of electric connection. Guarantee the system in high temperature, high humidity environment, good electrical connection performance, can make the system long-term stable and reliable operation.
5 circuit board
Circuit board using flame retardant epoxy board, the design of reasonable layout, take the line specifications, to meet the requirements of electromagnetic compatibility and stability of the circuit. Processing manufacturers should choose well-known manufacturers of products.
6 driver chip IC device
Drive circuit using the international famous brand of constant current driver chip. In the large temperature range, the high accuracy of the constant current output and high reliability, can make the display uniformity and reliability significantly improved. The main material of the display system should be certified by CE, FCC, UL, CCC, ISO9000 and so on. Believe that if you do the above, adhere to the reliable supporting facilities and materials and professional R & D design technology, will be able to reduce the failure rate of the display, and will greatly improve the reliability and stability of LED display.
