Description

A lighting art installation for urban landscape lighting

technical field

The utility model patent relates to a light box device, in particular to a lighting art device used for urban landscape lighting.

Background technique

At present, there are various forms of urban landscape lighting devices, mainly including acrylic light boxes, line lights, dot matrix characters, LED display screens, etc. Although all kinds of landscape lighting devices have the function of urban beautification and lighting, they also have certain defects, such as Acrylic material light box: The acrylic material light box picture is relatively simple and lacks changes. Line lights: Although line lights murals are rich in light effects, they can only appear in line pictures and cannot express specific pattern details. Moreover, the visual effect during the day is poor, and the wall screen effect cannot be taken into account during the day and night. Dot matrix characters: The picture effect is poor during the day, and the problem of leakage of luminous points is common. The pattern can only be viewed from a distance, and the visual effect at close range is poor. LED display: Although it can display a richer picture, the shape of the box has limitations and cannot be changed arbitrarily. In addition, the traditional wall reliefs and murals that are viewed during the day have high artistic appreciation, especially in the details of the picture, which can fully reflect the artistic aesthetics, but do not have the function of lighting at night.

SUMMARY OF THE INVENTION

The purpose of this utility model is to overcome the problems existing in the background technology, and to provide a lighting art wall device for urban landscape lighting, the device presents two different pictures of a pattern picture and a light effect picture during the day and night respectively Effect.

For achieving the above object, the utility model provides the following technical solutions:

The utility model relates to a lighting art device for urban landscape lighting, comprising a box body formed by a face shield, an outer vertical edge plate and a back plate being fixedly connected to each other, a partition and a light source are arranged in the box body, and the light source is connected to a lighting control system and a switching power supply, The mask is an opaque plate with meshes evenly opened on it, and a pattern picture of any style is sprayed on the outer surface of the opaque plate; on the back panel.

Further, the diameter of the mesh holes on the face mask is 1 mm to 5 mm, and the distance between the mesh holes is 1 mm to 5 mm.

Further, a light-transmitting plate is fixed on the inner side of the mask, and a pattern picture is spray-painted on the light-transmitting plate.

Further, the light sources on the partitions and the outer vertical edge panels fixed in the box are linear light sources, and a light homogenizing baffle is arranged at the light source, and the homogenizing baffle is fixed on the inner side of the mask.

Further, the light source fixed on the back panel in the box is a surface light source.

Due to the adoption of the above solution, the characteristics of the mask with mesh holes can be relatively complete to present the spray pattern, and have the characteristics of overall uniform reflected light and transmitted light. Reflection adjusts the purity of light color, so as to realize an art installation that restores the pattern effect of daytime with light effect at night. Or present different nighttime picture effects through the design and control of light and color. The picture effect presented during the day can be realized by spraying any style of pattern picture on the surface of the mesh plate mask of the box. In order to ensure the effect of the night light picture, the mesh diameter ranges from 5MM to 1MM, and the hole spacing ranges from 5MM to 1MM. The mesh mask can effectively filter the light source, prevent the generation of glare, and achieve the highest illumination value of urban landscape lighting at night. The viewing angle value of the best visual effect is 0 degrees perpendicular to the wall.

The material of the utility model includes resin, metal, wood and other materials, and this calculation takes the reflection data of the galvanized coating for calculation. According to the literature, it is deduced that the light reflectance ratio of the galvanized coating is 0.7～0.8. The value of this calculation is 0.7. D/R is the thickness-radius ratio, and f is the intrinsic light penetration coefficient. The value can be calculated when D/R=1 The f value is 0.563.

The numerical value obtained in the formula calculation proves that the mesh plate can effectively filter the light source, prevent the generation of glare, and achieve the illumination value of the urban landscape lighting. This calculation formula is suitable for the calculation of the average brightness and transmittance of devices with the same structure and different materials. In order to clarify the technical principle, only representative materials and relevant mesh values are used for light efficiency calculation.

The device is in the form of an independent box body, and the top of the box body is a mesh plate mask made of opaque material. By opening the box body, the components in the box can be easily replaced. The partition is fixed between the mask and the back panel in the box according to the pattern image shape and the area division of the light color of the light source, so as to achieve the area division of the pattern image shape and color. There is a uniform light baffle in the box, which can effectively adjust the light intensity of the linear light source, effectively control the glare generated by the linear light source, and at the same time realize the highlight effect, so as to present the best lighting picture effect. By using small fasteners and glue to fix the bottom plate and various lighting components inside the box, the large fasteners realize the fixation of the outside of the box and the wall to ensure the stability of the components inside the box and the external carrier.

The utility model can be applied to the related fields of various urban landscape lighting products such as walls, lighting sculptures, lamp pole decorations, and landscape lamps. It has the advantages of strong decoration, strong plasticity in appearance, wide application fields, and effective filtering of light pollution. At present, most of the urban landscape lighting devices on the market can only guarantee the visual effect at night, and the shape is extremely limited. The utility model can not only take into account the visual effects of daytime and nighttime, but also can realize the dynamic picture at night through program control, and is a lighting art device which combines art and lighting functions efficiently.
