The Design Scheme Of The Light Guide Panel
Dec 31, 2021
1. The design scheme of the light guide plate:
The laser dot scheme is adopted, which 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 reflections of the surrounding small dots and the "twisting" function of the large dots in the middle, completely free of dark lines and "black holes". And can make special effects.
2. Classification of light guide plate:
1. Press the shape
Flat plate: The light guide plate is rectangular when viewed from the point of light incident.
Wedge-shaped plate: also known as sloping plate, viewed from the point of light incident, one side is thick and the other side is thin into a wedge (triangular) shape.
2. Press outlets
Printing type: After the light guide plate is processed, the dots are printed on the reflective surface by printing, which 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.
4. 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.
