Types of production processes for light guide panels

  Production process type of light guide plate:

 1. Light guide plate production process: light guide plate production process are laser dot, screen printing, injection molding, free screen printing, etc.. Currently the most widely used, the highest uniformity of light efficiency belongs to the network type light guide plate. 2. light guide plate thickness: 0.5/1/2/3/4/5/6/8/10/12mm different industry sectors, different products choose different thickness of light guide plate, our company can be customized according to customer product requirements of different thickness, a variety of different sizes. 3. light guide plate into the way: divided into 1 side into the light, 2 side into the light, 3 side into the light and 4 side into the light. Side light, 3 side light and 4 side light. Commonly used is generally single-sided light as well as bilateral light, triangular light guide plate is generally three sides into the light. Round, square high-brightness type guide plate is generally four-sided into the light.4. Guide plate material: the production of light guide plate materials used, PMMA acrylic, PS, MS the three materials, currently the most commonly used is the highest light transmission rate, the highest temperature and pressure resistance of PMMA acrylic material, PMMA acrylic is also divided into cast acrylic, extrusion acrylic.

  The type of production process of light guide plate 

Light guide plate processing test specifications: First, cutting, cutting tools are generally available wood sawing machine, ordinary engraving machine, laser engraving machine, etc., which uses laser engraving machine for cutting light guide effect is the best. Second, polishing, with laser engraving machine processing of the plate without polishing. With the woodworking saw blade machine and ordinary engraving machine processing of the plate need to be cut and polished. 

Step 1: Use the hobby knife to level the cut, scrape off the chips left when cutting, and scrape the saw marks. 

Step 2: Use polishing machine or flame gun to polish the kerf, requiring the kerf to be smooth and flat, without obvious ripples or saw marks. Third, test, step one: the lamp on both sides of the light guide, with silver-plated reflective film (or reflective paper) wrapped around the lamp and double-sided adhesive. 

Step 3: Use silver-plated tape to seal the other side of the light guide plate mouth. Step 3: Place the light guide on the flat reflective paper; connect the lamp to the power supply and preheat for about 10 minutes (longer time is better). 

Step 4: With the naked eye or illuminance meter can see the light guide plate light guide brightness and uniformity.
