LED is very bright when just energized, after a period of time suddenly not bright or brightness attenuation, you can check whether the switching power supply is 12V LED misused into 24V. If there is no problem, check whether the input voltage of the switching power supply is 220V. If the LED brightness is high or low, check whether the input voltage and output voltage of the switching power supply are normal. Such as high voltage, will lead to LED burn out; If the voltage is low, the LED will not bright or brightness attenuation. If the user’s local voltage is very unstable, it is recommended that the user install a voltage regulator. If the noise is found in the use, it is likely that the quality of the drive power supply is not good, and the drive power supply can be replaced.
LED color temperature, the color of the light emitted by the light source is the same as the color of the light emitted by the black body at a certain temperature, the temperature of the black body is called the color temperature of the light source. The units are Kelvin. Glare refers to the visual discomfort caused by extremely bright objects or strong brightness contrast in the field of vision. Glare is an important factor affecting lighting quality. Synchronization, two or more than two LED lights in the specified time can normally run according to the way set by the program, generally refers to the internal control mode of LED lights.

However, the filament in incandescent lamp is easy to oxidize during long working time. In order to slow down the oxidation of the filament, some inert gas is usually filled into the bulb. In the working state, the temperature of the filament is very high, if we touch the bulb directly, it is easy to heat. This means that during the operation of the bulb, a large amount of electric energy is converted into heat and lost, which is a large energy consumption, and a large current passes through the moment of powerup.
During this World Cup match, a “C-position paid to watch the game” calm brother on the stand with a expressionless face, always staring at the LED screen became popular on the short video platform. He is King Kong, the LED screen engineer of Abison. As a 2000 square meter LED screen supplier for 8 pitches in this World Cup, Abison dispatched 2 service engineers to maintain the normal operation of the big screens. “My job is to make sure the LED screen is stable.” .
In order to improve the reliability of the product to meet the high-end market demand for high-quality LED display devices, part of the package has improved the structural design of the bracket, using advanced waterproof structural design, bending and stretching methods to extend the water vapor entry path of the bracket, while adding multiple waterproof measures such as anti-sink, waterproof step and water drain hole inside the bracket. It not only saves packaging costs, but also improves product reliability, and has been widely used in outdoor LED display products.
