Design scheme and classification of light guide panel

1. The design scheme of the light guide plate:

　　Using the laser dot scheme, it has the following characteristics:

　　 (1) Combining different acrylic materials and different ways of use, you can use a uniform and unified laser dot layout, or you can make different sizes of dot layouts according to different specifications and ways of use. Achieve the perfect unity of commonality and specificity.

　　 (2), the light guide is more uniform, and the uniformity can reach 90% or more.

　　(3). Effective use of the dense reflection of the surrounding small dots, and the "twisting" function of the large dot in the middle, completely free of dark lines and "black holes". And can make special effects.

2. Classification of light guide plate:

　　 (一). According to the shape

　　Plate: The light guide plate is rectangular when viewed from the light incident.

　　 Wedge-shaped plate: also known as a slanted plate, from the point of light incident, one side is thick and the other is thin into a wedge (triangular) shape.

　　(二). By branch

 　　Printing type: After the light guide plate finishes the shape processing, the dots are printed on the reflective surface by printing, and it is divided into two types: IR and UV.

　　Non-printing type: The dots are directly formed on the reflective surface when the light guide plate is formed. It is divided into chemical etching (Etching), precision mechanical characterization (V-cut), photolithography (Stamper), and internal diffusion.

　　 (3). Follow the light

　　Side light type: Place the luminous body (tube or LED) on the side of the light guide plate.

　　Direct type: Place the luminous body (tube or LED) under the light guide plate.

　　 (four). Press to shape

　　Injection molding: Use an injection molding machine to inject optical grade PMMA particles into a mold at high temperature and high pressure to cool and shape.

　　 Cutting and forming: The optical grade PMMA original board is cut to complete the finished product.
