Abstract
The utility model discloses a radiating structure of an LED display screen, comprising a box main body, wherein the box main body comprises an LED lamp plate and a driving circuit board that is positioned on the back surface of the LED lamp plate and is electrically connected with the LED lamp plate; the frontal surface of the LED lamp plate is provided with a plurality of LED lamps; and the driving circuit board is provided with a plurality of driving circuit modules that are used for driving the LED lamps. In the utility model, the box main body adopts a form that the LED lamp plate is separated from the driving circuit board, so that the radiating area of the box main body is increased; therefore, the radiating performance is good, and the service life of the LED lamp can be prolonged.
Description
Technical field
The utility model relates to a kind of LED display structure, especially relates to a kind of radiator structure of LED display.
Background technology
Existing LED display is that LED core is integrated into lattice module or pixel cell, it is display unit, again together with some display unit windings, join simultaneously by supply unit, every display unit all adopts square box that metal material makes as carrier, display unit is fixed on the casing, thereby forms a module casing, the plurality of module casing is assemblied to form LED display again.
As number of patent application is the demonstration module that 200620032321 Chinese patent has disclosed a kind of LED display, it contains drain pan and face shield, inboard, drain pan rear end face edge is provided with the pcb board of support and connection light emitting diode and the screw Connection Block of fixed visors, inboard, drain pan rear end face edge be provided with run through pcb board and packing colloid and be communicated with the pcb board backside space and face shield and packing colloid outside surface between the ventilation duct in space, by ventilation duct the heat of pcb board and LED is distributed.Yet, the demonstration module poor radiation of above-mentioned existing LED display, thus cause the serviceable life of LED short.
The utility model content
The utility model is to provide a kind of not only thermal diffusivity good at the defective that the above-mentioned background technology exists, and the radiator structure of the LED display of the long service life of LED.
For achieving the above object, the utility model discloses a kind of radiator structure of LED display, it comprises a casing main body and is fixed on plurality of fixed pin on the described casing main body, this casing main body comprises the drive circuit board that a LED lamp plate and is positioned at this LED lamp plate back side and is electrical connected with the LED lamp plate, described LED lamp plate front is provided with some LED lamps, described drive circuit board is provided with some drive circuit modules that are used to drive described LED lamp, and described fixing feet is fixed on the described LED lamp plate and fixes described drive circuit board.
In sum, the radiator structure of the utility model LED display is by being arranged to the form that the LED lamp plate separates with drive circuit board with described casing main body, just can increase the area of dissipation of described casing main body, thus perfect heat-dissipating not only, and can increase serviceable life of described LED lamp.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the three-dimensional exploded view of fixing feet of the present utility model shown in Figure 1;
Synoptic diagram when Fig. 3 is assemblied to form LED display and is fixed on the carrier for the utility model shown in Figure 1.
Embodiment
For further understanding feature of the present utility model, technological means and the specific purposes that reached, function, the utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
See also Fig. 1 and Fig. 2, the module casing of the utility model LED display comprises a casing main body 1 and is fixed on plurality of fixed pin 2 on this casing main body 1.Described casing main body 1 comprises the drive circuit board 12 that a LED lamp plate 11 and is positioned at these LED lamp plate 11 back sides and is electrical connected with LED lamp plate 11, described LED lamp plate 11 fronts are provided with some LED lamps 111, and described drive circuit board 12 is provided with some drive circuit modules 121 that are used to drive described LED lamp 111.
Described fixing feet 2 comprises a casing linking arm 21 and a magnetic arm 22 that links to each other with this casing linking arm 21.Described casing linking arm 21 is made by metal material, and it comprises a junction 211 and the spiro union portion 212 that links to each other with this connecting portion 211, and these connecting portion 211 1 ends and described casing main body 1 are fixedly linked.Described casing linking arm 21 is fixed on the described LED lamp plate 11 and fixes described drive circuit board 12, thereby can make described LED lamp plate 11 and described drive circuit board 12 secure.Described magnetic arm 22 is T-shaped, it comprise an adjutage 221 and by these adjutage 221 1 ends to around extend the discoidal magnetic portion 222 that forms.
See also Fig. 2 and Fig. 3, an end of described adjutage 221 is provided with screw thread, and described spiro union portion 212 is spirally connected with described adjutage 221.By the form of described fixing feet 2 being arranged to be connected with described magnetic arm 22 by casing linking arm 21, thus can be from making full use of existing parts on the market.Some described casing main bodys 1 are bolted together, and the magnetic portion 222 of described fixing feet 2 is placed on the carrier 3 that can attract each other with described magnetic portion 222, thereby just form a LED display.In the present embodiment, described carrier 3 is one can fix square iron plate on the wall.When the module casing of described LED display is assemblied to form LED display, only need magnetic portion 222 with described fixing feet 2 place on the carrier 3 that can attract each other with described magnetic portion 222, just can reliably fix, thereby not only be convenient to dismounting, and be convenient to increase and decrease the area of LED display.
In sum, the radiator structure of the utility model LED display is by being arranged to the form that LED lamp plate 11 separates with drive circuit board 12 with described casing main body 1, just can increase the area of dissipation of described casing main body 1, thus perfect heat-dissipating not only, and can increase serviceable life of described LED lamp.
