Description

LED illumination three-side turning device

Technical Field

The utility model relates to an outdoor advertising technical field, concretely relates to LED illumination is trilateral turns over.

Background

The three-side turnover billboard has two characteristics and advantages compared with the common outdoor guideboard: the advertisement carrying capacity is three times that of the common outdoor guideboards; secondly, the advertisement is attractive, and the attention of the passing crowds can be aroused due to intermittent turning and pause, so that a larger advertisement effect is realized; however, the existing three-face turning billboard is usually not provided with a lighting device, so that the advertisement is difficult to see at night and the media effect is poor if no additional projection lighting is added; the existing method is to add a billboard spotlight, which needs to install a fixing frame of the spotlight, has complex working procedures, large power consumption, complex maintenance and high-altitude operation, and has uneven reflected light of the external billboard spotlight; in another mode, the LED light source is arranged inside the three-side turnover face, the light guide plate is selected on the three-side turnover face, when an advertisement is turned on one turnover face, the LED light source is used for illuminating the advertisement attached to the light guide plate through the light guide plate material of the turnover face, and due to scattering of the LED light source, the illumination utilization rate is not high, and the illumination effect is influenced.

Disclosure of Invention

The utility model aims at providing a combine together LED light source and the turnover face that trilateral was turned over, and then promote illuminating effect, reduce trilateral LED illumination that turns over preparation and use cost and turn over.

In order to achieve the above object, the utility model adopts the following technical scheme:

an LED illuminated three-sided flip, comprising: braced frame, and set up a plurality of trilateral upset units and drive in the braced frame the drive arrangement that trilateral upset unit overturns, it is a plurality of trilateral upset unit interval sets up, drive arrangement includes motor and transmission shaft, and the spacer sleeve is established every a plurality of driver plates on the transmission shaft to and fix respectively the gear at trilateral upset unit both ends, it is a plurality of on the transmission shaft the driver plate respectively with the gear of trilateral upset unit corresponds the meshing, transmission shaft and every the center pin of trilateral upset unit is perpendicular, the transmission shaft is hollow spline shaft, and its characteristics lie in: the three-face turning unit is characterized in that three planar mirror reflection plates which are 120 degrees and have the same size are mounted on a central shaft of the three-face turning unit, three space upper covers are formed by the three planar mirror reflection plates, three light guide plates are connected with the three planar mirror reflection plates, LED chip lamps which are connected in series are transversely and longitudinally distributed on the two planar mirror reflection plates through epoxy resin, an electric slip ring is arranged on the outer wall of one end or two ends of the central shaft of the three-face turning unit, and when one turning face of the three-face turning unit is used for advertising, the electric slip ring is connected with all the LED chip lamps of one turning face during current advertising and supplies power, so that the lighting of the working turning face is realized.

The utility model has the advantages that: when all the LED chip lamps on one turnover surface work, due to the reflection effect of the plane mirror reflection plate, all light sources of the LED chip lamps during working can irradiate on advertisements installed on the light guide plate through the light guide plate, so that the light utilization rate is increased, the viewing distance of the advertising board is longer, and the illumination cost is reduced.

Detailed Description

The invention will be further described with reference to the following detailed description of the preferred embodiments in conjunction with the accompanying drawings:

an LED illuminated three-sided flip, as shown in fig. 1-3, comprising: braced frame 1 to and set up a plurality of trilateral upset units 2 and the drive in braced frame 1 the drive arrangement of the upset of trilateral upset unit 2, a plurality of trilateral upset unit 2 interval sets up, drive arrangement includes motor and transmission shaft 3, and the interval cover is established every a plurality of dials 4 on the transmission shaft 3 to and fix respectively at every gear 5 at trilateral upset unit both ends, a plurality of on the transmission shaft the dials 4 respectively with the gear 5 of trilateral upset unit corresponds the meshing, transmission shaft 3 is perpendicular with every the center pin of trilateral upset unit 2, transmission shaft 3 is hollow spline shaft, the center pin 8 of trilateral upset unit 2 install three planar mirror surface reflection boards 6 that are 120 the same size, three planar mirror surface reflection boards 6 enclose into three spaces and cover three light guide plates 9, in a space enclosed by the two plane type mirror reflection plates 6 and the light guide plate 9, the two plane type mirror reflection plates 6 are transversely and longitudinally covered with LED chip lamps 7 which are adhered and connected in series through epoxy resin, an electric slip ring is arranged on the outer wall of one end or two ends of a central shaft 8 of the three-face turning unit 2, and when one turning face of the three-face turning unit 2 is used for advertising, the electric slip ring is connected with all the LED chip lamps 7 of one turning face during current advertising and supplies power, so that the lighting of the working turning face is realized.

The utility model has the advantages that: when all the LED chip lamps 7 of one turnover surface work, due to the reflection action of the plane type mirror reflection plate 6, all light sources of the LED chip lamps 7 during working can irradiate on the advertisement installed on the light guide plate 9 through the light guide plate 9, the light utilization rate is increased, the viewing distance of the billboard is longer, and the illumination cost is reduced.

The above-mentioned embodiments are only described for the preferred embodiments of the present invention, and are not intended to limit the concept and scope of the present invention, and the ordinary engineers in this field should fall into the scope of the present invention for various modifications and improvements of the technical solution of the present invention without departing from the design concept of the present invention.
