Abstract

The utility model provides a triangular prism rotating light-changing advertisement screen which is an advertisement display device integrating the advantages of a triangular prism rotating advertisement screen, an internal lighting type lamp box and a scanning type neon lamp advertisement. A prism composed of translucid materials is provided with a light source body; the two ends of the prism are provided with rotating shafts; the rotating shafts are connected with conducting wires; the light source shaft is connected between the upper rotating shaft and the lower rotating shaft; the rotating shaft on one end of the prism is provided with a bidirectional motor; the motor and the conducting wires are respectively connected with the I/O interface output terminal with a computer PC; the movement track of the periphery of the prism is provided with a microswitch which is connected with the I/O interface terminal of the computer.

Description

The internal irradiation type triangular prism rotates and becomes the light advertisement screen

The utility model relates to a kind of advertisement display.

Existing triangular prism upset advertisement screen though can change the different picture of three width of cloth, does not have interior irradiation source, night effect with regard to non-constant; Though and the transparent lamp box of existing internal irradiation type all has good display effect night on daytime, but do not possess turn over function, image content is changeless, and dynamic good not as scan-type neon-light advertisement screen, but that neon-light advertisement shields the display effect on daytime is relatively poor; The LED dot matrix advertisement screen chroma-luminance of computerizeing control is poor, and cost is higher.

The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and provides a kind of internal irradiation type triangular prism to rotate change light advertisement screen, and it is the advantage of triangular prism upset advertisement screen, internal irradiation type lamp box and scan-type neon-light advertisement to be concentrated be the advertisement display of one.

The utility model is reached by following measure: a plurality of prisms of being made up of light transmissive material are formed large-size screen monitors and are admired display screen, the light source body is arranged in each prism elements, there is rotating shaft at prismatic two ends, be connected with lead in the rotating shaft, the light source body is connected between the lower rotary shaft, and a two-way motor is arranged in the rotating shaft of a prismatic end, and described motor links to each other with the I/O interface output terminal of computer PC respectively with lead, on the peripheric movement track of prism a microswitch is arranged, it links to each other with the I/O interface input end of computing machine.

The light transmissive material that constitutes prismatic panel adopts plastic lamp sheet of polypropylene or look glass.

Fig. 1 is an external structure simplified schematic diagram of the present utility model.Fig. 2 is the simplified schematic diagram that connects between prism elements about the advertisement screen that the utility model proposes.Fig. 3 is the I/O interface principle simplified schematic diagram of computer PC in the utility model.Fig. 4 is prismatic positioning principle simplified schematic diagram

As shown in Figure 1, three panels of each prism elements (2) constitute with light transmissive material, and prismatic surface has various figures, and some prisms can be arranged in bigger plane.The very high fluorescent lamp group (3) of brightness is installed in the prism, prism has a pair of concentric rotating shafts (1) up and down, light power is connected with the external control light power by connecting the lead (4) that in the rotating shaft, by contacting and will feed current to fluorescent tube between the axle at two ends and bearing.Every countershaft is used as power by an either-rotation motor that links to each other with axle (5), and the drive lip pole unit pivots.When needs are made giant-screen to the prism lengthening to enlarge display area, solve open air reinforcing and windproof pressure energy power after prism is connected up and down, as shown in Figure 2, establishing a back up pad (6) between prism up and down, it is fixed on the dielectric panel (7) and links to each other with framework (8).Series connection is conducted electricity by connecting shaft for the prismatic interior lamp source after the one.So not only strengthened prismatic physical strength but also guaranteed that it had certain Wind-Pressure Resistance ability.

Shown in Fig. 3,4, motor links to each other prismatic positioning signal T respectively with light power with the IO interface of computer PC ₁T _nSend into the input end of I/O interface by microswitch (9) as the input signal of computer PC, and the output terminal of interface is exported M respectively ₁M _nSignal is controlled motor rotation, L ₁L _nSignal is controlled light and is changed, and after power switch K connected, advertisement screen just gave at computing machine and carries out work under the programmed instruction of putting.Driven by motor prismatic moment turns over 120 degree, and putting in place stops, and forms a complete picture, and at this moment, prism touches the microswitch disconnection; Intermittently a moment, rotate 120 degree more synchronously and form another new picture.

The advertisement screen that provides according to the utility model, it all is the independent action unit that the light and shade of each prismatic sense of rotation, speed and light changes, under industrial computer PC programs control, prism can different directions and three pictures of the automatic conversion of rotational speed, and by changing prismatic inner light source light and shade, hundreds of display effects can be obtained, artistic effect can also be produced in the part, as the three phases of the cover of one in animation action with strong innervation.

Light disturbs between adjacent two prisms in order to avoid, and is provided with this plate of movable shadow shield (10) and is articulated on the framework between them, and when prism rotated, plate can swing around pin joint.This product is cheap, simple in structure, and is bright in luster bright.

Claims

1, a kind of internal irradiation type triangular prism rotates and becomes the light advertisement screen, comprise the prism of forming by light transmissive material (2), light source body (3) is arranged in the prism, it is characterized in that there is rotating shaft (1) at prismatic two ends, be connected with lead (4) in the rotating shaft, the light source body is connected between the lower rotary shaft, in the rotating shaft of a prismatic end a two-way motor (5) is arranged, described motor links to each other with the I/O interface output terminal of computer PC respectively with lead, one microswitch (9) is arranged on the peripheric movement track of prism, and it links to each other with the I/O interface input end of computing machine.

2, advertisement screen according to claim 1 is characterized in that the light transmissive material that constitutes prismatic panel adopts plastic lamp sheet of polypropylene or look glass.
