The SM1204BWC "Biscuit" LED module is a discrete LED indicator that offers a wide range of applications in various industries and applications. This series of LED modules is designed as a small, bright, reliable, and efficient illumination device for a variety of uses. It offers excellent value in terms of cost, size, and features. This article will discuss the application field and working principles of the SM1204BWC LED module. The SM1204BWC LED modules are designed for a variety of functions such as remote indication, status indication, alarms, and more. They are particularly suitable for panel indication, automobile and boat fuse indication, Dios, electric power security panel indication, and electric appliance wiring indication, among others. The SM1204BWC LED modules are also used in boat applications such as LED navigation lights and has also been used as a backlight for night driving.The SM1204BWC LED module employs a dual-trigger mode; that is, the LED module automatically triggers the light source to turn on when it is supplied with DC power or when it detects a voltage-dependent input. This is done through the use of a high-voltage integrated circuit (HVIC) MOSFET, which is responsible for the on/off control of the LED system. When the logic goes high, the HVIC will set the LED system to turn on and when the logic goes low, the LED system will turn off. The working principle of the SM1204BWC LED module is mostly dependent on the current driving capability of the HVIC MOSFET. The HVIC MOSFET is designed to provide the necessary current for the LED module to operate properly; thus, when the HVIC is supplied with the proper DC voltage, it will cause the LED module to turn on and vice versa. The current range of the HVIC varies from 10mA to 200mA, however the actual range depends on the application and can be much higher. In addition, the HVIC can be configured to operate in either current-direct or polarity-changing modes. The SM1204BWC LED module also offers various safety features. It has a short-current protection mechanism that automatically shuts down the LED module if the voltage exceeds 8V or if the current exceeds 4.5A. This feature helps prevent accidental burnouts and damages due to overload. It also has built in EMI filter that helps reduce noise and interference from external sources. The SM1204BWC LED module is also RoHS compliant, ensuring that it is free of hazardous materials. In conclusion, the SM1204BWC LED module is a highly reliable, cost-effective, and feature-rich discrete LED indicator. It has a wide range of uses in many industrial and consumer applications. It is also designed for safety and has excellent current driving capability as well as EMI filter to reduce noise and interference. This makes it an ideal choice for a variety of applications.
