Description

A puzzle-type three-dimensional light guide plate and lighting fixture

technical field

The utility model relates to a light guide plate, in particular to a jigsaw type three-dimensional light guide plate suitable for various types of lighting, art lighting, decorative lighting, decorative materials, window, cabinet, display stand lighting, etc., and a lighting system with the light guide plate. lamps.

Background technique

In the field of liquid crystal display manufacturing, the light guide plate is used to pass the light emitted by fluorescent lamps, CCFL, LED and other light sources through the light guide point or light guide groove designed according to the optical principle. Under the action of the reflective film (reflector) and the diffusion film, Converts a directional or point light to an area light. In order for the light guide plate to emit light evenly, it must pass through various light guide points of different densities and sizes to ensure that the efficiency of light reflection in all directions is basically the same. However, the existing light guide plate is made of a whole piece of material, and the trimmed scraps cannot be well utilized, resulting in waste of resources, and the shape of the light guide plate does not change much, thus limiting the use of the light guide plate in certain areas. Applications in various aspects, such as TV backlight, lighting, decoration, advertising, signage and so on. In order to effectively utilize the material of the light guide plate, the Chinese patent 201020528532.X applied by Shenzhen Anrong Optoelectronics Products Co., Ltd. on January 19, 2011 discloses a puzzle-type light guide plate, which includes a light guide plate and a The light guide point on one side of the light plate, and the light guide plate is formed by splicing light guide units of various shapes into one body. The invention of this utility model makes the light guide plate no longer made of a single piece of material, which will not cause waste of resources, and can be spliced according to the situation to form the required shape of the light guide plate. However, because these technical solutions only have light guide points on one side of the light guide plate, the three-dimensionality of the light passing through the light guide plate is not strong, especially in the lighting fields that require three-dimensional effects such as artistic lighting and decorative lighting. , the effects of such light guide plates are not ideal.

Detailed ways

Please refer to FIG. 1 , the lighting fixture of the present invention includes a three-dimensional light guide plate 1 and a light source 2 . The light source 2 can be arranged on the bottom surface or the side of the puzzle-type three-dimensional light guide plate, preferably on the side of the puzzle-type three-dimensional light guide plate. in:

Please refer to Figure 2 to Figure 6 together. The puzzle-type three-dimensional light guide plate 1 includes a first sub-light guide plate 11 and a second sub-light guide plate 12 , and the puzzle-type three-dimensional light guide plate is formed by splicing the first sub-light guide plate 11 and the second sub-light guide plate 12 . The first sub-light guide plate 11 is provided with a first light guide network point 111 , and the second sub-light guide plate 12 is provided with a second light guide network point 121 . The first light guide network point and the second light guide network point constitute the light guide network point of the puzzle-type three-dimensional light guide plate, and the first light guide network point is located on the bottom surface of the puzzle-type three-dimensional light guide plate, and the second light guide network point is located on the top of the puzzle-type three-dimensional light guide plate noodle. In this specific embodiment, the first light guide dots are arranged on the bottom surface of the first light guide plate, the second light guide dots are arranged on the top surface of the second light guide plate, and the top surface of the first light guide plate and the top surface of the second light guide plate There are no light guide points on the bottom surface. The size, shape and density of the first light guide network point and the second light guide network point are all different.

Utilize the distance gap formed by the first light guide network point 111 and the second light guide network point 121 made on the front and back sides of the bottom surface and the top surface of the jigsaw type three-dimensional light guide plate, guide the light emitted by the light source 2 out of the first light guide network point 111 and the second light guide network point 111 and the second light guide network point 121. The two light guide dots 121 form light guide dot patterns of different shades on the surface of the jigsaw three-dimensional light guide plate, forming a more obvious and three-dimensional pattern.

Of course, the jigsaw-type three-dimensional light guide plate can also be formed by splicing more than two sub-light guide plates. The top surface of the first light guide plate and the bottom surface of the second light guide plate may also be provided with light guide grid points.

The light guide dots form various luminous patterns. The sub-light guide plates can be rectangular, triangular or other shapes, and the jigsaw-type three-dimensional light guide plate can be a regular shape formed by splicing each sub-light guide plate, or an irregular shape. Each sub-light guide plate can be spliced with a mechanical connection structure, such as buckle connection, etc., or the sub-light guide plate can be supported by a transparent plate or clamped on both sides, or spliced by glue. The sub-light guide plate can be made of transparent, frosted or stained glass, PC and acrylic material.

Of course, dyeing materials or self-luminous materials can also be printed on the first light-guiding network point and the second light-guiding network point to form dyeing materials or self-luminous material network points to construct various colors of luminous patterns or display without light source illumination Various glowing patterns.

The puzzle-type three-dimensional light guide plate can be spliced into different shapes according to needs, such as flat plate, cylinder, polygon cylinder, etc.

See Figure 7. In this specific embodiment, the puzzle-style three-dimensional light guide plate 6 is spliced by the first sub-light guide plate 61, the second sub-light guide plate 62, the third sub-light guide plate 63 and the fourth sub-light guide plate 64, and the first sub-light guide plate The bottom surface and the top surface of the light plate 61 , the second sub-light guide plate 62 , the third sub-light guide plate 63 and the fourth sub-light guide plate 64 are all provided with light guide grid points.

The fabrication method of the utility model jigsaw puzzle type three-dimensional light guide plate is as follows:

Step 1: Design the required light guide points first, and make various light guide points of different shapes, sizes and densities on the surface of the collected light guide plate. Of course, it can also be spliced into a light guide plate and then made into light guide dots, so the effect will not be too good, and sometimes some printing dots will be missed. Light guide dots can be made by any method of printing, laser, engraving, molding or etching. The light guide plate is made of any material such as acrylic, glass, or PC.

Step 2: According to the requirements of the design shape, cut the light guide plate with light guide points into multiple sub-light guide plates. The shape of the sub-light guide plates can be any shape, such as rectangle, rhombus, triangle or other shapes.

Step 3: Finally, according to the design requirements, each sub-light guide plate is spliced into a whole, that is, the jigsaw puzzle-type three-dimensional light guide plate of the present utility model is formed.

The utility model can make use of corner materials of different sizes to make sub-light guide plates, and then splice the sub-light guide plates into jigsaw-style three-dimensional light guide plates of various shapes. Since the bottom surface and the top surface of the light guide plate are provided with light guide points, the light passing through the puzzle-type three-dimensional light guide plate forms a relatively obvious and three-dimensional pattern, so the light passing through the puzzle-type light guide plate has stronger three-dimensionality and is more suitable for Art lighting and decorative lighting and other lighting fields that require three-dimensional effects. The utility model changes the image of the plane lamp, and is completely suitable for various lighting, decoration materials and the like.
