Simple analysis of the classification and characteristics of laser light guide plates
1. Classification of laser light guide plates:
1. By shape
Flat plate: The light guide plate is rectangular when viewed from where the light enters.
Wedge-shaped plate: also known as the inclined plate, from the point of view of the light, one side is thick and the other is thin into a wedge (triangle) shape.
2. By outlets
Printing: After the light guide plate is processed, the dots are printed on the reflective surface by printing, which is divided into IR and UV.
Non-printing type: The dots are directly formed on the reflective surface when the light guide plate is formed. It is further divided into chemical etching (Etching), precision mechanical characterization (V-cut), photolithography (Stamper), and internal diffusion.
3. According to incoming light
Side light type: place the illuminant (light tube or LED) on the side of the light guide plate.
Direct type: Place the illuminant (light tube or LED) under the light guide plate.
4. Press forming
Injection molding: use an injection molding machine to inject optical-grade PMMA particles into the mold with high temperature and high pressure to cool and form.
Cutting and forming: The optical grade PMMA original plate is finished by the cutting process.
Second, the characteristics of the laser light guide plate:
1. It can be arbitrarily cut into the required size, or can be spliced together, the process is simple, the production is convenient; the light conversion rate is high (more than 30% higher than the traditional board), the light is uniform, and the service life is long. It can be used normally indoors for more than 8 years, Safe and environmentally friendly, durable and reliable, suitable for indoor and outdoor use;
2. Under the same area of luminous brightness, the luminous efficiency is high and the power consumption is low;
3. Can be made into special shapes, such as circles, ellipses, arcs, triangles, etc.;
4. Under the same brightness, thinner products can be used to save costs;
5. Any light source can be used, point line light source can be converted into surface light source, the light source includes LEDCCFL (cold cathode lamp), fluorescent lamp, etc.
