Our company is the frist company that develops this range of products and masters the technique of Engraving light panel. The finished product is able to compare the beauty with the same range of products in foreign countries. It is based on the optics theory that precision machineries can be made intonetwork ditches of different width on the high polymer organic materiais, and then the side optical source will have light effect such as refraction, reflection and widespread reflection among the netting twiness in order to transfer the linearity optical source into flat source.
