Manufacturing process of light guide plate

Since the 1990s, science and technology have continued to develop, and the production methods of light guide plates have gradually improved, resulting in printing production that is different from the early ones. Compared with it, we call it "non-printing" Mode". 1. Long service life. Engraving is a physical process, and the service life of the light guide plate is mainly related to the quality of the organic glass substrate. Printed boards tend not to last long. For example, most of the ultra-thin printed board light boxes used in Beijing subway stations that have been used for less than 2 years have experienced a serious drop in light conductivity.

2. The light guide is more uniform. When the width of the engraved light guide plate is 1.2M, the light guide uniformity can still reach more than 80%.

3. The light guide effect is better and the performance is more stable. Under the condition of the same thickness, the light guiding effect of the engraved light guide plate is obviously better than that of the printed plate. Especially the large-format format has better light conductivity and more stable performance. When the door width of the 10MM thick engraved light guide plate reaches the target 1.2M, using the 30WT5 light source, the surface illumination can reach more than 2000LUX.

4. Adopt flexible technology. Each specification of the printed light guide plate must be plated separately, and the finished product cannot be cut at will, so there are shortcomings in application. The laser light guide plate can be produced as a whole plate, cut and used at will, or it can be made into a special plate with individual specifications. For products with large production volumes and multiple specifications, such as luminous signs, etc., the advantages are obvious. It has more obvious and significant advantages over the traditional engraved light guide plate (precision mechanical scoring method).

1. The light guide point design is more reasonable. Combine different acrylic materials. Different ways of use require different laser dot solutions. A uniform and uniform laser dot layout can be used. We can also create network layouts of different sizes according to different specifications and usage methods. Achieve the perfect unity of common use and exclusivity.

2. The light guide is more uniform and the uniformity is higher. Different acrylic materials and personalized dot designs make the light uniformity higher, and the light uniformity can reach 90 or more. Very even overall.

3. Personalized dot design, the effect is better. Effectively utilizes the dense reflections from surrounding small points.
