Since the liquid crystal splicing screen lamp is 80% more efficient than the conventional incandescent lamp, the large-screen splicing component and the driver circuit have a large amount of heat dissipation, and the heat dissipation directly affects the life span and work efficiency of the lcd video wall. In hot summer, to make the LCD video wall non-stop working of 7*24 hours, the problem of heat dissipation should be given full attention.
Heat dissipation is a major factor affecting the illumination intensity of liquid crystal splicing system lamps. Generally speaking, according to the way of removing heat from the heat sink, the heat dissipation mode can be divided into active heat dissipation and passive heat dissipation. Active heat dissipation is to forcibly remove the heat from the heat sink by a heat sink such as a fan; the so-called passive heat dissipation means that the heat source of the large-screen splicing light source is naturally radiated into the air through the heat sink, and the heat dissipation effect depends on the size of the heat sink. So how do we maintain the heat dissipation problem of the LCD video wall in the hot summer’s daily use?
Firstly, maintain the ambient ventilating and normal temperature of the LCD video wall through the environmental temperature control, for example, by y using a fan or an air conditioner to control the ambient temperature or avoiding the long time non-stop working of the LCD video wall.
Secondly, regular inspection technicians check on time. Regularly check the use of various display screens, to develop a good inspection habit. It can also solve the problem of LCD video wall board failure caused by high temperature.
Last but not least, the use of thermal conductive materials. The LCD splicing screen adopts a splicing screen with more high-quality and durable thermal conductive materials, which not only saves maintenance cost, but also can dissipate heat in time.
