Professional terms often heard in outdoor LED large screens

The main application environment of outdoor LED large screens is the harsh environment of wind, rain, sun and frost resistance. Outdoor LED large screens not only have high requirements for waterproof, but also have high requirements for dustproof, moisture-proof, freeze-proof, and low-temperature resistance. Let's explain the explanations of terms often encountered in outdoor LED large screens, hoping to help you. Outdoor LED large screen unit panel brightness: when it comes to brightness, we think of the word high brightness, this parameter is a parameter that people pay more attention to. Brightness is a more complicated issue in LEDs. The brightness we refer to in LED unit boards is usually the luminous intensity and transparency, which are generally obtained by adding the relative degrees of each unit board.

Outdoor LED large screen unit board size: usually refers to the dimensions such as length, width and height. The maximum length of a single connection, this parameter is often used in large-scale projects, it means the number of connected LED unit boards in a series of LED unit boards. This is related to the size of the connecting wire of the LED unit board, and it should be customized according to the actual situation.

Outdoor LED large screen unit board voltage: it is a very important parameter in LED unit boards, and 5V low-voltage unit boards are relatively common at present. When connecting the power supply and the control system, be sure to check the correctness of the voltage value before powering on, otherwise the LED unit board will be damaged. Outdoor LED large screen unit board waterproof level: This is mainly for outdoors, and it is an important indicator to ensure that the LED unit board can work outdoors for a long time.

Generally, the waterproof level of LED large screens must reach at least IP65 in an open-air environment. Outdoor LED large screen unit board color: it is the most basic parameter in the LED unit board, and different colors are used in different occasions. According to the color type, it can be divided into three types: single primary color, double primary color and full color.

Single primary color is a single color, which cannot be changed, and it can work when it is connected to the power supply; full color is the color that can be controlled to each unit board, and the effect of displaying pictures and videos can be realized when the number of unit boards reaches a certain level . Full-color modules need to be added with a control system to achieve dynamic effects. Working temperature of outdoor LED large screen unit board: The normal working temperature of LED unit board is usually between -18°C and 58°C. If the required range is relatively high, special treatment should be carried out, such as adding air conditioner or exhaust fan .

LED large screen luminous angle: The luminous angle of the LED unit board without a lens is mainly determined by the LED lamp beads, and the different luminous angles of the LED lamp beads are also different. Generally, the luminous angle of the LED lamp beads provided by the LED large screen manufacturer is used as the LED unit. The light angle of the board. .
