Abstract
Description
Technical Field
[0001] This utility model relates to a double-sided hanging advertising machine, belonging to the technical field of hanging advertising machines. Background Technology
[0002] Previous commercial display double-sided hanging advertising machines typically used a sheet metal frame and a stamped back panel. The disadvantages were poor heat dissipation and bulkiness.
[0003] In terms of optics: A side-lit optical solution is typically used, where ordinary LED chips (19) and LED strips are installed on the side of the display screen. The LED chips are usually small 0.2W chips, with a luminous intensity range of approximately 26 to 28 lumens. The installation structure of a side-lit optical solution generally consists of a reflective film at the bottom, followed by a light guide plate, one or two brightness enhancement films, and the LCD screen itself. A significant drawback of this structure is its low brightness (typically around 250 cd / m²). 2 Up to 350 cd / m 2 If such products are used in well-lit public places like banks, supermarkets, and shopping malls, their low brightness will result in a dim and unclear viewing experience, severely impacting people's vision. If the brightness of such optical solutions could reach 500 cd / m², the effect would be significantly improved. 2 Up to 700 cd / m 2 When applied to the aforementioned public places, the visual effect will be much better, but at the same time, the power consumption will increase significantly, and the heat generation will also be greater. Such products generally do not have a heat dissipation method, and in this application environment, phenomena such as black screen and black spots are prone to occur.
[0004] Based on the above shortcomings, it is necessary to apply for a double-sided hanging advertising machine to improve upon these shortcomings. Utility Model Content
[0005] The main purpose of this invention is to provide a double-sided hanging, multi-directional heat dissipation, and high-reflectivity advertising machine.
[0006] The objective of this utility model can be achieved by adopting the following technical solution:
[0007] A double-sided hanging advertising machine includes a double-sided hanging advertising machine frame for limiting the machine's position, and LED display screen one and LED display screen two are respectively installed on both sides of the double-sided hanging advertising machine frame;
[0008] The double-sided hanging advertising machine has fasteners distributed inside the frame, a reflector installed inside the fastener, a light guide plate installed on the reflector, a diffuser installed on the light guide plate, and LED beads installed on both sides or in the middle of the reflector.
[0009] A device separation box is installed on one side of the double-sided hanging advertising machine frame. A heat dissipation component is installed inside the device separation box. A connecting component is installed on the outside of the heat dissipation component on the device separation box. An insertion limit component is installed on the double-sided hanging advertising machine frame.
[0010] Preferably, the heat dissipation components include heat dissipation holes, heat dissipation mesh, and heat dissipation fan. The equipment separation box has heat dissipation holes, a heat dissipation mesh, and a corresponding power control box is installed inside the heat dissipation mesh.
[0011] Preferred connecting components include connectors, networking components, connectors, power connection holes, and cooling fans;
[0012] Connectors are installed at the top and bottom of the equipment separation box, and network components are installed at the bottom of the connectors. A power control box is installed at the bottom of the cooling fan, and network components are installed at the bottom of the connectors. The network components are installed on the connection port, and a power connection hole is installed at the bottom of the cooling mesh. The power connection hole is connected to the power control box.
[0013] The preferred insertion limiting component includes an insertion rail, a limiting stop and a limiting frame. An insertion rail is installed on the double-sided hanging advertising machine frame, and a limiting stop is installed on the outer end of the insertion rail. An LED display screen is installed on the outer end of LED display screen one and LED display screen two of the double-sided hanging advertising machine frame.
[0014] Preferably, the heat dissipation holes are distributed on both sides of the equipment separation box, and the heat dissipation fans inside the heat dissipation mesh have two sets of structures.
[0015] Preferably, the space between LED display screen one and LED display screen two is a cavity structure, and the upper and lower sides of the double-sided hanging advertising machine frame are covered with insertion rails.
[0016] The beneficial technical effects of this utility model are as follows:
[0017] This utility model provides a double-sided hanging advertising machine.
[0018] Structural approach: We adopted a structural approach combining aluminum profiles, aluminum alloy sheet metal, and galvanized steel sheets. We also added a smart fan module integrated with the fan.
[0019] Optical Solution: For the dual-sided LCD display, one side employs an edge-lit high-brightness optical solution. Regarding the selection of LED chips, we use 0.5W large-chip LED chips, with a light intensity range of approximately 60 to 65 lumens. The edge-lit optical solution's installation structure consists of a DJX225P reflector at the bottom, followed by a light guide plate, a two-in-one composite film DOP, and a DBEF. This structure can increase the brightness of the backlight module to 10,000-20,000 cd / m². 2Since the light transmittance of LCD screens is typically around 5%, this results in the overall brightness of this side-lit solution being typically around 500 cd / m². 2 Up to 1000 cd / m 2 (Left and right), the other side adopts a direct-lit OD10 high-brightness optical solution. In terms of LED lamp bead 19 selection, we use 0.5W large chip LED lamp bead 19.
[0020] Optical Solution: For the dual-sided LCD display, one side employs a side-lit high-brightness optical solution. For the LED chips, we use 0.5W large-chip LED chips. The mounting structure consists of a DJX188 backlight at the bottom, followed by a 1.5T PC diffuser plate, a two-in-one composite film POP, and a DBEF. This structure can increase the brightness of the backlight module to 40,000-80,000 cd / m². 2 Since the light transmittance of LCD screens is typically around 5%, this solution results in a lower overall brightness (typically around 2000 cd / m²). 2 Up to 4000 cd / m 2 (Left and right) The technology of this invention can be applied in indoor conditions with direct sunlight, such as shopping malls and other public places with excellent lighting. The content displayed on the LCD screen can still be clearly viewed with bright and vivid picture quality. In terms of structure, aluminum alloy profiles and aluminum alloy sheet metal are more beautiful, have better heat dissipation, are lighter, and are rust-proof and durable than galvanized sheet metal structures.
