With the development of science and technology, outdoor decorative landscape lighting for commercial advertising and other purposes is receiving more and more attention and application; Lines are used for contour lighting, and can be combined into a large pixel screen in an array to play various video animation effects synchronously online. It has become a main product in lighting projects; LED point light sources will always encounter or More or less some glitches. Outdoor lighting manufacturers teach you how to judge led point light problems and solutions:
Fault 1: After the power is turned on, the controller and the front part of the lamps work normally, but the rear lamps are abnormal starting from a certain lamp?
Answer: This situation is generally because some of the lamps in the back fail to receive the signal normally. The reasons are usually as follows:
(1) If the IC of individual lamps is faulty or the signal line before and after the lamp is damaged, generally replace the first lamp that does not light up in the abnormal position or the lamp in front of it.
(2) When writing the program, the number of point light sources is less (for example, 9000 are actually used, but only 8000 are written in the program), so the latter part will not have animation effect, and you need to contact the manufacturer to rewrite the program
Fault 2: After the power is turned on, the controller works normally, but the changing position of the lamps is abnormal, which is different from the designed video screen effect?
Answer: This situation is caused by the inconsistency between the order of installing the lights and the designed wiring diagram. It is necessary to adjust the order and position of the installed lights according to the designed wiring diagram, or to input the actual arrangement of the installed lights. Reprogram the program to the computer
Fault 3: After the power is turned on, the point light sources can change normally, but some of the point light sources display different colors than others?
Answer: This situation is generally due to the damage of one of the three chips R, G and B of the lamp bead, resulting in lack of color in the display. Just replace the point light source in question.
