Abstract
The utility model has been announced a kind of LED display, comprise backup circuit breaker power supply, multiple viewing areas and multiple Switching Power Supply, and it is its power supply that each viewing area is connected with Switching Power Supply described at least one, described backup circuit breaker power supply all can be connected with each viewing area and be powered by connecting viewing area.Adopt the LED display of technical solutions of the utility model, owing to being provided with backup circuit breaker power supply, in the time breaking down for one in multiple Switching Power Supplies, backup circuit breaker power supply is this breakdown switch power supply of automatic replacement at once, thereby guarantee that LED display continues normal work, guarantees display quality.The reliability of LED display is obviously improved, met preferably the live work requirements to LED display of advertisement broadcasting and sports tournament.
Description
Technical field
The utility model relates to LED display technique field, is specifically related to a kind of LED display.
Background technology
In recent years, LED(Lighting Emitting Diode, light emitting diode) important media that display screen shows as a kind of information, appear at more and more in people's life.It can show or loop play word, figure and image information in real time, have that display mode is abundant, sight is strong, displaying contents amendment is convenient, brightness is high, demonstrations is stable and the multiple advantage such as life-span length, be widely used in the numerous areas such as commercial advertisement, sports tournament and transport information report.
LED operating voltage is lower, therefore LED display inside all handlebar electric main transfer the Switching Power Supply of DC low-voltage to.LED display power consumption in the time of work is larger, and a complete LED display need to have multiple Switching Power Supplies to power, a certain size region in the corresponding LED display of each Switching Power Supply.
The uninterrupted broadcasting of circulation and the on-the-spot broadcasting of sports tournament etc. of commercial advertisement all have higher requirement to the functional reliability of LED display, if LED display inside has indivedual Switching Power Supplies to break down, LED display just there will be the blank screen in larger region or show undesired, have a strong impact on visual effect, therefore need to improve.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of LED display, and certain Switching Power Supply that solves current LED display breaks down and causes in LED display relevant range blank screen or show abnormal problem.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of LED display, comprise backup circuit breaker power supply, multiple viewing areas and multiple Switching Power Supply, and to be connected with Switching Power Supply described at least one be its power supply in each viewing area, described backup circuit breaker power supply all can be connected with each viewing area and be powered by connecting viewing area.
In preferred technical scheme, described LED display also comprises multiple Detection & Controling circuit, each described viewing area all connects a described Switching Power Supply by a described Detection & Controling circuit, and described backup circuit breaker power supply is connected respectively with all Detection & Controling circuit, thereby can show with control circuit and connect the viewing area corresponding with control circuit with this demonstration by any one, and be this viewing area power supply.
In preferred technical scheme, described LED display also comprises equalizing control circuit, and each described viewing area all connects described flow control circuit, connects described backup Switching Power Supply and multiple Switching Power Supply by described equalizing control circuit.
The beneficial effects of the utility model are:
Adopt the LED display of technical solutions of the utility model, owing to being provided with backup circuit breaker power supply, in the time breaking down for one in multiple Switching Power Supplies, backup circuit breaker power supply is this breakdown switch power supply of automatic replacement at once, thereby guarantee that LED display continues normal work, guarantees display quality.The reliability of LED display is obviously improved, met preferably the live work requirements to LED display of advertisement broadcasting and sports tournament.
Brief description of the drawings
Fig. 1 is the schematic block circuit diagram of a kind of LED display in the utility model embodiment one;
Fig. 2 is the schematic block circuit diagram of a kind of LED display in the utility model embodiment two.
Embodiment
Embodiment mono-
A kind of LED display that this embodiment provides as shown in Figure 1, comprise backup circuit breaker power supply, multiple viewing areas and multiple Switching Power Supply, and it is its power supply that each viewing area is connected with Switching Power Supply described at least one, described backup circuit breaker power supply all can be connected with each viewing area and be powered by connecting viewing area.
Adopt the LED display of technical solutions of the utility model, owing to being provided with backup circuit breaker power supply, in the time breaking down for one in multiple Switching Power Supplies, backup circuit breaker power supply is this breakdown switch power supply of automatic replacement at once, thereby guarantee that LED display continues normal work, guarantees display quality.The reliability of LED display is obviously improved, met preferably the live work requirements to LED display of advertisement broadcasting and sports tournament.
In preferred technical scheme, described LED display also comprises multiple Detection & Controling circuit, each described viewing area all connects a described Switching Power Supply by a described Detection & Controling circuit, and described backup circuit breaker power supply is connected respectively with all Detection & Controling circuit, thereby can show with control circuit and connect the viewing area corresponding with control circuit with this demonstration by any one, and be this viewing area power supply.
Embodiment bis-
A kind of LED display that this embodiment provides as shown in Figure 2, be with the difference of embodiment mono-, described LED display also comprises equalizing control circuit, each described viewing area all connects described equalizing control circuit, connect described backup circuit breaker power supply and multiple Switching Power Supply by described equalizing control circuit, equalizing control circuit makes the output current size of each Switching Power Supply basically identical.In the time that all Switching Power Supplies are all normally worked, because standby power supply is also in normal work, therefore the output power of each Switching Power Supply can be little when not adding standby power supply, so just improved the reliability of Switching Power Supply.In the time that one of them Switching Power Supply breaks down, the output power of each Switching Power Supply reaches the size while not adding standby power supply, and LED display still can normally be worked, so larger raising the reliability of LED display.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
