Differences in light guide plate characteristics

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 plexiglass substrate. Printing plates often cannot be used for a long time. For example, most of the ultra-thin printed board light boxes that have been used in Beijing subway stations for less than 2 years have experienced a serious decline in light conductivity.

2. The light guide is more uniform. When the width of the carved 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. In the case of the same thickness, the light guide effect of the engraved light guide plate is significantly better than that of the printed board. Especially for large format specifications, the light conductivity is better and the performance is more stable. The 10MM-thick engraved light guide plate uses 30WT5 light source when the width of the door width reaches the goal of 1.2M, and the surface illumination can reach more than 2000LUX.

4. Adopt flexible craftsmanship. Each specification of the printed light guide plate must be made separately, and the finished product cannot be cut at will, so there are shortcomings in the application. The laser light guide plate can be made as a whole plate, cut and used at will, or it can be made into a special plate with a separate specification. For products with large production volume but many specifications, such as light-emitting signs, the advantages are obvious.

It has more obvious and remarkable advantages with the traditional engraving light guide plate (precision mechanical scribing method).

1. The design of light guide point is more reasonable. Combine different Acrylic materials. Different ways of use use different laser dot schemes. Either a uniform and unified laser dot layout can be used. It is also possible to make different sizes of outlet 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 is higher. Different acrylic materials and personalized dot design make the light guide even higher, and the light evenness can reach 90% or more. The whole is very uniform.

3. Personalized dotted design, better effect. Effective use of dense reflections from surrounding small spots.
