Description

Cabinet for LED display board with heat dissipation function The present invention relates to a cabinet for an LED display used to construct an LED display, and more particularly to a cabinet for an LED display equipped with a heat dissipation function that can extend the lifespan of the LED display and reduce energy consumption. Generally, LED display panels are equipped with multiple LED modules. When manufacturing and installing LED display panels, the modules are arranged in a matrix configuration, and power supplies and various signal processing devices to drive these modules are appropriately connected and positioned. Recently, as the size of LED display panels has gradually increased, the number of LED modules installed on them has also increased dramatically. When the number of LED modules in an LED display panel or screen exceeds a certain level, significant difficulties arise in its installation and maintenance. Even if only one LED module installed in a large display panel fails, it may become necessary to dismantle the entire panel. Considering the above circumstances, a method has recently been developed and widely adopted in which multiple LED modules, for example, 4 to 8, are combined to form an LED display cell or LED unit, and these are appropriately combined on-site to install an LED display. Such an LED display cell or unit is commonly referred to as an LED cabinet. Regarding LED cabinets, for example, Korean Registered Patent No. 10-2004673 (Title: LED LED display with dual-power launching structure), Registered Patent No. 10-2000904 (Title: LED display panel equipped with cabinet with one-touch fastening structure), Registered Patent No. 10-2211951 (Title: Internal air circulation system for road display panels), Registered Patent No. 10-2399609 (Title: LED display unit device for display panels with improved ease of installation), Registered Patent No. 10-2399610 (Title: LED display unit device for display panels with easy LED module attachment/detachment), Published Patent No. 10-2022-0167612 (Title: LED screen assembly for large advertising panels having a one-touch fastening structure), and Published Patent No. 10-2024-0123118 (Title: Automatic Flattened LED display panels and automatic flattening systems for the same) are disclosed. An LED cabinet houses LED modules on its front and is equipped with various circuit components and power supplies to drive them. The power supply typically consists of a Switching Mode Power Supply (SMPS), which emits a significant amount of heat during the process of generating power for the LED modules. In particular, since LED display panels are usually installed on the exterior of buildings, the cabinet is kept as airtight as possible to protect the internal components from dust and moisture. For this reason, the internal temperature of the LED cabinet can rise significantly. If the internal temperature of the LED cabinet rises excessively, the LED chips and other electronic components may be damaged. Specifically, a rise in internal temperature reduces the luminous efficiency of the LED chips. Furthermore, if the luminous efficiency of the LED chips decreases, the amount of power required to maintain the same brightness level increases, leading to a rapid increase in energy loss from the LED display panel. Conventional LED cabinets are equipped with a separate cooling fan to manage internal temperature. However, since the cooling fan releases internal heat to the outside through forced convection, the internal space of the cabinet is set to a semi-open state to facilitate air convection. Furthermore, this semi-open state of the cabinet presents a disadvantage in that the electronic components inside the cabinet are exposed to dust or moisture from the outside. The attached drawings are intended to illustrate embodiments according to the present invention. Therefore, it should be understood that some components may be exaggerated or omitted for a more efficient explanation of the embodiments.
