Abstract

The utility model relates to a displaying device with array light sources moving for imaging, which comprises a light emitting array and a supporting frame. The utility model is characterized in that the displaying device is a light emitting array formed from light emitting elements; an electronic circuit and a required power supply which are used for controlling the light emitting elements to be turned on or off are installed on the displaying device; a moving device is adopted to make the light emitting array move in a set plane or a set curved plane. During the course of movement, the electronic circuit of each light emitting element is turned on or off according to a preset program. When a certain moving speed is achieved, because of the human eye visual persistence effect, observers can see complete characters or patterns. The utility model has the advantages of simple structure, no need for a large amount of light emitting elements, novel and unique displaying effects, and also convenient operation.

Description

Array light source mobile imaging display device

The utility model relates to a kind of display device, particularly a kind ofly utilizes human eye vision to persist effect and obtains the device of display effect.

A large amount of at present advertisement or information display screens that use are to utilize light emitting diode to make display matrix, have advantages such as rich and varied, that editor is quick.But this display screen need be used a large amount of light emitting diodes, and needs configuration computer to control, so the expense costliness.Chinese patent CN2088730U discloses a kind of comprehensive display device, it is to make whole screen do 360 degree rotations, utilize human eye vision to persist principle, make the observer in 360 degree scopes, all can obtain positive observing effect, but this display device needs a large amount of light emitting diodes equally, complex structure, the expense costliness is not easy to promote.

The purpose of this utility model is that design is a kind of by display device single-row or that the ordered series of numbers luminescent device is formed, light regularly or extinguish by each luminescent device in these luminescent device array motion processes, make the observer observe complete literal or pattern because of human eye vision persists effect.

The display device of utilizing human eye vision to persist principle provided by the utility model, by luminous array, electronic circuit, mounting and telecontrol equipment are formed.Its technical scheme is: make bar-shaped luminescent device array and be installed on the mounting, by telecontrol equipment it is moved on plane of setting or curved surface.Each luminescent device is lighted by preset program by electronic circuit control or is extinguished in motion process, and when reaching certain movement speed, because the persistence of vision of human eye, the observer just can see a complete literal or pattern.

The maximum difference of the utility model and existing dot matrix LEDs screen is only to adopt row or an ordered series of numbers luminescent device, and control system adopts independently electronic circuit simultaneously, need not be equipped with computer.So it is simple in structure, easy to use.In addition, literal that the utility model demonstrates or pattern are aerial as swimming in, and do not block the object at rear portion in the time of demonstration, and very novel uniqueness is suitable as medium and small advertising message screen.

Describe the structure of the utility model embodiment in detail below in conjunction with accompanying drawing.

Fig. 1 is the structural representation of the utility model embodiment 1.

Fig. 2 is the structural representation of the utility model embodiment 2.

In embodiment 1, adopt luminous array to make the technical scheme of circular motion.Luminescence unit 2 and electronic circuit 3 that luminous as shown in Figure 1 array 1 is made up of light emitting diode are formed, and are controlled the light on and off of the light emitting diode in each luminescence unit by preset program by electronic circuit.Luminous array 1 is fixed on the whirligig 4, and luminous array 1 can be row or some row, but considers spin balancing, and lighting rod is 2～4 row preferably, are symmetrically distributed on the whirligig 4.The surfaces of revolution of whirligig 4 can be a support shape, also can be discoidal, and the rotating shaft of the rotating shaft of its bottom center and dc generator 5 links.Motor 5 is fixed on the mounting 6, to keep stable.When motor 5 rotated, driven rotary device 4 and luminous array 1 were rotated like this.Meanwhile, the light emitting diode in each luminescence unit 2 is lighted by preset program by electronic circuit control or is extinguished.When reaching certain rotational speed, because of there is visual persistence effect in human eye, the observer will see a complete literal or pattern.Change the control program in the electronic circuit, just can obtain different literal or pattern.

Embodiment 2 is a kind of shaped as frame structure display screens, adopts the technical scheme of doing plane motion on the rectangular frame of luminous array lower guideway on being equipped with.As shown in Figure 2, on the framework up and down of rectangular frame 7 guide rail 8 is housed, luminous array 1 upper and lower side is embedded in the guide rail respectively.Linear electric motors 5 are equipped with at the rear of framework 7.Do plane motion by the luminous array of linear electric motors 5 push-and-pulls 1 along guide rail like this, can demonstrate literal or pattern equally.
