Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

Examples

Fig. 1 is a schematic structural diagram of a thin lamp 010 according to this embodiment. In the figure, the x-coordinate represents the horizontal direction in space, the y-coordinate represents the vertical direction in space, and z represents the direction perpendicular to the x-y plane. Referring to fig. 1, the present embodiment provides a thin lamp 010, which comprises a lenticular lens 100, a perforated plate 200, and a backlight 300.

Perforated sheet 200 is used to provide a parallax composite image containing luminaire image information. The backlight 300 is used to provide light energy for display. The lenticular lens 100 serves to project parallax images in respective different spatial directions, thereby forming viewpoints. When the left eye and the right eye of a person are at different viewpoints, the parallax images of the corresponding lamps can be seen, and therefore stereoscopic vision is generated. Meanwhile, in the space, the light rays for imaging can form lamp illumination.

Referring to fig. 2, the backlight 300 is composed of a light source 310, a reflective housing 320 and a light guide plate 330. The upper surface of the reflection shell 320 is left empty for emitting light, and the inner surfaces of the rest positions are coated with high-reflectivity materials, so that the reflection shell has a high reflection coefficient and can reflect most of light. The light source 310 is an LED, and is disposed within the reflective housing 320 for providing light energy. The light guide plate 330 is disposed in the reflective housing 320, and scattering particles are uniformly etched thereon. The light is continuously reflected in the light guide plate 330 in a total reflection manner until it is incident to the scattering particles. The scattering particles may destroy the total reflection condition, so that the light is emitted, and the light guide plate 330 may be upwardly emitted with uniform intensity because the scattering particles are uniformly distributed.

Referring to fig. 1, the surface of the perforated sheet 200 is made of a material with high reflection coefficient, and the perforated sheet and the reflective housing 320 of the backlight 300 form a reflective cavity. The light emitted from the light source 310 can only pass through the opening of the perforated plate 200, and the rest of the light is reflected by the surface of the perforated plate 200 and then returns to the cavity again to be reused, so that the light efficiency is high.

Referring to fig. 3, the perforated plate 200 is disposed on the upper surface of the reflective housing 320, and the pixels are arranged in an array. Each pixel has the same length and width dimensions, and the pixel value is expressed by the size of the opening. The larger the pixel value, the larger the aperture size, which allows more light to pass through, the higher the overall brightness. Since the perforated plate 200 is dispersed in the horizontal direction by the lenticular sheet 100, the openings of all the pixels on the perforated plate 200 have the same size in the horizontal direction, and the size of the openings is determined by the size of the openings in the vertical direction.

For further explanation, please refer to pixel case a 310 and pixel case B320. Pixel case a has a larger pixel value than pixel case B. The opening 311 in pixel case a has a larger dimension in the vertical direction than the opening 321 in pixel case B, so that it allows more light to pass through, and the overall brightness is larger within the pixel size range.

Referring to fig. 3, the apertures of the perforated plate 200 are arranged to form a parallax composite image. The pixels of the same column belong to the same parallax image. For example, the pixels in the pixel column 210 are all from the same parallax image.

Referring to fig. 4, in the present embodiment, there are 4 different parallax images used for describing the lamp, and the 4 parallax images are alternately arranged according to the pixel columns. The lenticular lens can project 4 parallax images to 4 different spatial directions, thereby forming a viewpoint. At each viewpoint position, the human eye can see a parallax image corresponding thereto.

The utility model discloses in directly demonstrate the stereographic image of lamps and lanterns because of the stereographic image, it has the same vision sense organ with entity lamps and lanterns, nevertheless constitutes because of it only comprises cylindrical lens grating 100, the board of punching 200, backlight 300 three layer construction, and its actual physics thickness is thinner, can make things convenient for it to practice thrift the physical space.
