Description

Technical Field

[0001] The present application relates to the technical field of signboards, and in particular to a heat dissipation structure of a luminous signboard. Background Art

[0002] A signboard is a sign with patterns or marks on its surface, often used for reminders or instructions. Generally, signboards are made of plastic or metal and do not have the function of luminescence. Generally, signboards install LED lamps inside the signboards. The LED lamps can emit light so that pedestrians can better observe the sign. With the acceleration of urbanization, LED luminous signs have been widely used in advertising, traffic instructions, safety warnings and other fields due to their energy saving, environmental protection, high brightness and long life.

[0003] The inventor believes that in traditional technology, LED light sources will generate a large amount of heat during operation, and luminous signboards generally only dissipate heat through heat dissipation holes. If the heat cannot be dissipated in a timely and effective manner, it will seriously affect its luminous efficiency and service life, and may even cause safety hazards such as fire. Therefore, in order to solve the above problems, this application provides a heat dissipation structure for luminous signboards. Utility Model Content

[0004] In order to solve the problem that the luminous signboards in traditional technology generally only dissipate heat through heat dissipation holes, if the heat cannot be dissipated in a timely and effective manner, it will seriously affect its luminous efficiency and service life, and may even cause safety hazards such as fire, the present application provides a luminous signboard heat dissipation structure.

[0005] The present application provides a heat dissipation structure for a luminous signboard, including a base and an air intake assembly, wherein a transparent lampshade is fixedly connected to the surface of the base, and a plurality of strip seats are fixedly connected to the surface of the base and located inside the transparent lampshade at equal intervals, an LED lamp tube is installed on the top of the strip seat, and a frame-shaped heat dissipation plate is installed on the surface of the strip seat and located on the periphery of the LED lamp tube, and heat dissipation fins are provided on both side walls of the frame-shaped heat dissipation plate.

[0006] Preferably, the air intake assembly includes a circular groove provided on one of the side walls of the transparent lampshade, an air intake fan is installed inside the circular groove, and a dust screen is installed on the end surface of the circular groove located on the outer side wall.

[0007] Preferably, a plurality of heat dissipation holes are formed on the side wall of the transparent lampshade away from the air intake fan.

[0008] Preferably, two connecting ears are fixedly connected to one side of the base, and mounting holes are provided inside the two connecting ears.

[0009] Preferably, the inner side wall of the frame-shaped heat dissipation plate contacts the surface of the LED lamp tube.

[0010] In summary, this application has the following beneficial technical effects:

[0011] 1. The LED lamp tube generates heat when it is working. The heat generated by the LED light source is quickly conducted to the inside of the frame-shaped heat sink. The heat dissipation fins increase the contact area between the heat sink and the outside air, which greatly promotes the heat dissipation function of the heat sink and dissipates it through the heat dissipation fins. Then, the heat is effectively dissipated through air convection. The heat inside the transparent lampshade is dissipated to the outside through the heat dissipation holes. Compared with the existing technology, this application can effectively dissipate the heat inside the luminous signboard.

[0012] 2. Start the air intake fan through the switch. The air intake fan will absorb the external gas. The dust and impurities in the gas will be adsorbed on the dust screen, thereby preventing the dust and impurities from entering the inside of the transparent lampshade with the gas and causing pollution to the internal LED lamp tube.
