Common Fault Problems and Solutions for LED Point Light Sources Modules

In recent years, domestic landscape lighting has developed rapidly. Outdoor decorative landscape lighting lighting for the purpose of beautifying urban landscapes and commercial advertising is being valued and applied to more and more. It can be used to embellish the decoration, and it can be combined into lines for contour brilliance. But LED dot -point light sources always encounter more or less failures in actual use. Below, I will introduce some of the common fault phenomena and analysis solutions for you in detail. Fault 1: After the power is served, the controller fault light (ERROR) flashs, the light source is not bright, and there is no animation effect output? Answer: This situation is generally because the controller does not read the card correctly, and the valid control program is not output. The reason may be: 1.SD card is empty, no effect file 2.SD card program file name error 3.SD card card 3.SD card card 3.SD card card 3.SD card card 3.SD card Formatting as required before copying the effect file 4. The effect file and the lamp chip, the controller model in the SD card do not match, you need to contact the manufacturer to re -make the effect file 5. After replacing the new SD card Bad possibilities faulty: After the power is served, the controller indicator is normal, there is signal output, but the LED point light source module has no effect change? Answer: In this case, there are generally the following reasons: 1. Check whether the signal and controller of the lamps is correctly connected. 2. External control lamp signal has an advancement/out of the direction, check whether the control signal from the signal of the light in front End in 3. Check whether the model selected when making the effect file in the SD card*. LeD was consistent with the chip used in the current lamps. 4. The lamp and the controller must be together, that is, the ground line of the lamp should be the ground line. GND is connected to a fault three: After the controller and the lamp are connected, the effect changes, but the lamps are flashing, and the controller indicator shows normal? A: The ground line between the controller and the lamp is not connected 2. Lantern The power supply voltage of less than 3. The effect in theSD card is wrong. The lamp chip and the chip of the actual lamps when the effect is done. 4. The distance from the controller to the first lamp (distance> 10 meters), the signal transmission is unstable Failure 4: After the power is applied, the controller and the previous part of the lamp are working normally. The lamp is not normal after a certain lamp starts? Answer: This situation is generally the lamp behind the lamps that failed to receive the signal normally. The reasons are usually as follows: 1. Individual lamps IC IC failure or the signal line is damaged before and after the light. The lamp can be written less when writing the program (for example, 9,000 pieces are actually used, and only 8,000 are written in the program). In this way, there is no animation effect in the latter part. : After power -on, the controller works normally, the lamp is abnormal, and the effect of the video screen is different? Answer: This situation is caused by inconsistency of the order of installing the lights and the designs. You need to adjust the sequence and location of the lamp according to the designed ride diagram, or enter the arranging of the actual installation lamp. Go to the computer to re -prepare the program failure 6: After the power is passed, the LED point light source module can change normally, but there are some point light sources that show the color different from other? Answer: This situation is generally due to the damage of a lamp R, G, and B chip, which causes the display of color shortage. You only need to replace the problem with the point of light. Intersection Answer: 1. First confirm whether the protection switch on the side of the SD card has been unlocked. The direction of the unlocking is the SD card gold needle. 2. The protection lock has been opened as required, but it is still unable to format. If the device is broken, please replace the SD card reader 3. If the above operation is still unable to solve the formatting problem, please change the SD card and re -test
