PMMA acrylic is divided into Cast acrylic, extruded acrylic, our company uses Mitsubishi cast acrylic for laser dots, and uses Chimei and other brand-new acrylics for screen printing.

Second, the light guide plate application:

     1. Panel light lighting field: conventional large panel lights have sizes of 600*600, 1200*600, 1200*300, and various large panel lights such as 450, 800, and small panel lights have sizes of 3, 4, 5, and 6 ,8 inches,

      2. Table lamp lighting field: there is no fixed size in the field of table lamp. Each manufacturer has different design sizes according to the product. Like the light guide plate of panel light, it is also divided into two schemes: round and square. The light guide plate of table lamp needs to be pasted on the dot surface. Reflective paper, paste a layer of diffusion film on the light-emitting surface, which can fully ensure that the product emits evenly.

      3. Backlight field: The light guide plate is widely used in the field of backlighting. Like mobile phone displays, various button displays, most electronic product displays are inseparable from the backlight display, and its structure is very similar to desk lamp applications. The following pattern examples are used in conjunction with a layer of reflective film and a layer of diffusion film:

      4. Advertising light box backlight field: Light guide plate is also widely used in advertising light box field. It belongs to high-end application with the soft brightness of the side light and uniform visual effect. Of course, the cost of this application method is higher than that of ordinary light boxes. Many of them are much larger in size than the lighting light guide plate. They are generally non-standard customization. The general size of the lighting and backlight fields is below 1200mm, and the advertising light box often has a size of more than 2000mm, or even more than 3000mm.

      5. The field of light guide lighting for special-shaped lamps: the application of light guide plates in this field mainly needs to combine the creativity of the lamp designer, a good imagination, and the needs of the market to create a unique product, which may be explosive for customers. payment,.

     6. Brand logo indication field: The traditional logo is displayed through patterns. When the light guide plate appears, the designer has more space in this field, making our display effect more three-dimensional.
