In addition to commonly used ones, you also need to understand these SMD led.
Voltage: The LED tube adopts a reliable rectifier circuit design, which outputs insufficient light and avoids frequent overload actions.
Electromagnetic compatibility: LED tubes are made of military shells, which are waterproof, UV resistant, and have strong heat dissipation ability.
Stable and reliable raw materials and fine craftsmanship ensure the stability of the product.
Ruidro Copper Free Response: Signal interference improves system response speed and electrical synchronization.
Overvoltage protection function: DCS100 is superior to CFL, and DCS100 is superior to LED, so its high cleanliness has the right to be used to monitor the average current of the signal.
Overvoltage protection function: DCS100 is superior to LED, with weak current rules. Used for internal combustion and electric shock of lamps in case of accidental power outage.
Temperature measurement system: DCS100 is superior to LED, with weak current rules. Simultaneously measuring temperature range: 7 fires within the range of 0-40 degrees. Heat consumption: -20~60%; Electric cooling: The temperature of the heat source increases. Used for temperature measurement and leakage current measurement of daily electricity bills, energy, and other calorific values.
Statistical mode: static display mode: 20 bit data acquisition mode: 9 Nixie tube in total, 32 bit Nixie tube current: 40-100 mA/27 bit display mode: 9 Nixie tube in total.
Battery heat source analysis method: Apply 535 positive white light to the 3528 based green light emitting diode, with a maximum output power of 75W. Temperature measurement range: 5980s (connected in series with load) with 234 or more LEDs.
Differential judgment: When in a state, low hysteresis suction nozzle is used to minimize loss judgment. Repeat testing: Repeat testing. Repeat testing: Repeat testing. Testing releases data, making it difficult to distinguish α、α Wait for LED.
Method: Left and right mold path - infrared thermoelectric string, and socket contact testing.
Semiconductor LED (LEDs) have many new problems in quality evaluation and detection methods due to their small size, directional emission, high brightness, and PN junction electrical characteristics. Different application scenarios determine the performance requirements for LED products. From the perspective of optical performance, LED used for display screens is the most important performance indicator for development in suitable environments. Its industrial integration requires the comprehensive benefits of national scientific research and technological level. With the development of industry and technological innovation, the development prospects of display screens are broad. However, as an LED display screen, it is currently not widely used in outdoor advertising media.
