led light box is the use of led as a light source, with energy saving and environmental protection, pure light color, long life and other advantages of the new light box. led light boxes are widely used in wedding photography, home decoration, mobile advertising and other fields. With its widespread use, the knowledge about led light boxes is also spreading. This article will introduce you to the power calculation of led light boxes.   Power estimation of led light box   If you only need to estimate the power of the led light box to meet the demand, you can estimate it according to the following methods:   1. This method estimates power by estimating current. Assuming that each string of led lamp beads is calculated according to the 20mA standard, then the power consumption of each string of led lamp beads is about 220V*0.02A=4.4W   2, this method is based on the number of each string of light beads to estimate the power of the led light box. First of all, we must count the number of each string of led lamp beads (if the number of work can be calculated with the average number), and then calculate the power of different color lamp beads, and finally add. For example, assume that the power consumption of white and blue lamp beads is basically equal, that is, the power consumption of each lamp bead is about 3V*0.02A=0.06W; The power consumption of red, green and yellow lamp beads is basically equal, and the power consumption of each lamp bead is about 1.7V*0.02A=0.035W, and then multiplied by the total number of lamp beads.   3, if it is a running horse lamp, it is converted according to the working condition ratio of the light. It is assumed that it is on for 1 second every 3 seconds, that is, the power consumption *1/3 when the full light is on. If the full light power consumption is 4.4W, the actual power consumption is 4.4W*1/3=1.5W.   led light box power actuarial   If the estimation does not meet your requirements, you can choose accurate measurement. Precise measurement is more certain than estimation, but the process requires the use of relevant tools. Accurate measurement can be carried out in the following ways:   1. Use A multimeter to measure the actual output voltage V of the controller and the actual working current A of each string of lamp beads, then the actual power consumption P=V*A of each string of lamp beads. If it is running horse lamp, it is still converted according to the proportion of the above working conditions.   2. Use power monitors, smart sockets and other power meters to connect them to the front end of the led light box controller to test the actual AC power consumption of the light box. In the use of power timing, we need to pay attention to the point that if it is connected to the back end of the led light box controller (that is, DC) calculated power consumption also consider the efficiency of the light box controller, generally calculated by 80%, then the total power consumption of the led light box = measured power consumption /0.8.

The programming method of LED dynamic light box The programming of LED dynamic light box involves multiple steps such as hardware connection, software programming and debugging.   Explain in detail   1. Hardware connection:   The LED dynamic light box needs to be connected to a computer or other control device. Usually, the connection is achieved through a serial port, parallel port or USB interface. Ensuring that all hardware is properly connected and running stably is a prerequisite for programming.   2. Software programming:   Choose programming software: According to the technical specifications and control requirements of the LED light box, choose the appropriate programming software. Common programming software include LED Studio, Magic LED and so on. Writing programs: In programming software, write programs according to design requirements. The program can include lighting animation, text display, picture scrolling and other functions. Through programming to achieve a variety of LED light box display effect.   Debugging and testing: After the completion of programming, the program is downloaded to the LED light box for debugging and testing. Make sure the lighting effect is as expected and make any necessary adjustments.   3. The importance of debugging and testing:   Debugging and testing is a very important part of the programming process. Through debugging, you can ensure the stability and safety of the LED light box; Through testing, the correctness and effect of the program can be verified. Only after adequate debugging and testing, in order to ensure the normal operation of the LED light box and the expected effect. Matters needing attention   In the programming process of LED dynamic light box, the following points need to be noted:   1. Familiar with the technical specifications and control requirements of LED light boxes, choose the appropriate programming software and tools.   2. When writing the program, it is necessary to consider the hardware limitations and power supply of the light box to avoid problems such as overload or short circuit.   3. In the debugging and testing process, carefully check the working condition of each part to ensure the safe operation of the light box.

LED light box waterproof mainly through the design of a reasonable waterproof structure and the use of waterproof materials to achieve.   The waterproof design of the LED light box is the key to ensure its stable operation in wet or rainy environments. In the production of LED light boxes, waterproof measures usually start from the following aspects:   First, choose a waterproof material. The shell of the LED light box should be made of materials with good waterproof performance, such as aluminum alloy or stainless steel, etc. These materials themselves have certain water resistance and strong corrosion resistance. At the same time, the internal circuit board and components should be sealed with waterproof potting glue to prevent short-circuit or damage caused by water penetration. Waterproof potting adhesive can not only effectively isolate water, but also enhance the structural strength of the light box and extend the service life.   Secondly, design a reasonable waterproof structure. The waterproof structural design of the LED light box is crucial, which determines the overall waterproof performance of the light box. During the production of the light box, ensure that all joints are tightly waterproof, such as using waterproof sealing strips or adhesive tapes. In addition, for wires or cables that need to penetrate the housing, they should be protected with waterproof joints or waterproof sleeves to prevent moisture from seeping through the joints. In the interior of the light box, a reasonable drainage structure should also be set up, so that it can be discharged in time when the rain infiltrates, to avoid damage to the light box caused by water.   Furthermore, pay attention to installation location and maintenance. When installing LED light boxes, try to avoid installing them in low-lying areas prone to water to reduce the risk of rain infiltration. At the same time, regular maintenance of the light box is also an essential link. By regularly checking whether the waterproof seals are intact and the drainage system is unblocked, potential water leakage problems can be discovered and dealt with in time to ensure the long-term stable operation of the light box.   In summary, LED light box waterproof is a comprehensive project, which needs to start from many aspects such as material selection, structural design, installation location and maintenance. By taking reasonable waterproof measures, the waterproof performance and service life of the LED light box can be significantly improved to ensure that it can work stably in a variety of harsh environments.
