Abstract
The utility model discloses a variable information board, which comprises an electric cabinet and a display panel, wherein the display panel consists of light-emitting devices which are orderly arranged; and a light sensor is arranged on the outer side of the electric cabinet and connected with a light controlled module in the electric cabinet. In the utility model, the light intensity of the variable information board changes with the change of the external environment light intensity, so that the information released by the variable information board can be always seen clearly.
Description
Technical field
The utility model relates to a kind of LED display device, is specifically related to a kind of variable information board.
Background technology
Variable information board is the visual plant of traffic and the issue of traffic guidance information, it is to be the traffic information display equipment of basic display unit with the LED luminescent device, have figure and literal Presentation Function, for the safe operation of traffic provides effective guarantee.
In every performance index of variable information board, brightness of display screen is a very important index, has only enough brightness just can make variable information board still high-visible under solar radiation.Current variable information board can reach the maximum brightness of 8000-15000cd/m2, also is easy to distinguish under the strongest sunlight.But night surrounding environment darker, particularly do not having on the highway of light, this brightness is just very dazzling, the driver could adapt to dark environment again through the time through several seconds after the variable information board, again see the road surface situation clearly, this procedure of adaptation of several seconds threatens very big to traffic safety, just traffic hazard may take place if there is something special in this highway section.In the city, strong excessively brightness also can be disturbed road periphery resident's normal life.Simultaneously such brightness power consumption is also bigger, can reduce the serviceable life of LED.
To sum up, its light intensity of existing variable information board is invariable, therefore, at red-hot afternoon of sunshine, because the light intensity of external environment is higher than the light intensity that luminescent device is launched on the variable information board far away, therefore, human pilot on the highway can be difficult to see institute's information releasing on the variable information board, in like manner, and at light intensity more weak night, it is dazzling that the light intensity that luminescent device is launched on the variable information board then can seem, influences the sight line of human pilot.
The utility model content
For solving the problems of the technologies described above, the utility model proposes a kind of variable information board, the light intensity of its display screen can automatically adjust according to the light intensity of surrounding environment, makes variable information board not be subjected to the influence of ambient light intensity, has improved visual sharpness.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of variable information board comprises electric cabinet and display panel, and described display panel is made up of the luminescent device of marshalling, and the casing of the described electric cabinet outside also is provided with optical sensor, and the interior light-operated module of described optical sensor and described electric cabinet is connected.
Preferably, the arranged outside of described optical sensor has protective cover.
Pass through technique scheme, the utility model has been set up optical sensor on variable information board, by the optical sensor sensing of light intensity power to external world, make the luminous intensity of the light-operated module controls luminescent device in the electric cabinet, thereby make the display panel of variable information board adjust its luminous intensity, guaranteed that shown information remains good sharpness on the display panel according to the variation of ambient light intensity.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below.
Fig. 1 is the structural representation of the disclosed a kind of variable information board of the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described.
The utility model proposes a kind of variable information board, the light intensity of its display screen can automatically adjust according to the light intensity of surrounding environment, makes variable information board not be subjected to the influence of ambient light intensity, improves visual sharpness.
Referring to the structural representation of a kind of variable information board shown in Figure 1, it comprises display panel 11 and the luminous electric cabinet 12 of control display panel 11, and display panel 11 is made up of the luminescent device LED lamp 13 of several marshallings.The casing outside of electric cabinet 12 also is provided with optical sensor 14, is covered with the protective cover 15 that shields on it.
For example at red-hot afternoon of sunshine, the light intensity of external environment is higher, optical sensor is passed to light-operated module with the light intensity data that is sensed, light-operated module is handled the data that received, and control LED lamp 13 improves luminous intensity, make the light intensity of display panel become big, help human pilot to see information shown on the display panel clearly.In like manner, at light intensity more weak night, to the sensing of light intensity and the transmission of data, light-operated module is controlled the LED lamp automatically according to the light intensity level of pre-stored and is reduced luminous intensity, makes the shown information of display panel clear not dazzling by optical sensor.
Wherein, according to the size of external environment light intensity, can make light-operated module carry out the control of a plurality of light intensity level, the luminous intensity that makes variable information board changes with the variation of ambient light intensity, remains visibility clearly.
The utility model is to have set up optical sensor on variable information board, by the optical sensor sensing of light intensity power to external world, make the luminous intensity of the light-operated module controls luminescent device in the electric cabinet, thereby make the display panel of variable information board adjust its luminous intensity, guaranteed that shown information remains good sharpness on the display panel according to the variation of ambient light intensity.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined herein General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
Claims (2)
1. variable information board, comprise electric cabinet and display panel, described display panel is made up of the luminescent device of marshalling, it is characterized in that, the casing of the described electric cabinet outside also is provided with optical sensor, and the interior light-operated module of described optical sensor and described electric cabinet is connected.
2. a kind of variable information board according to claim 1 is characterized in that the arranged outside of described optical sensor has protective cover.
