China's LED industry has been showing a rapid growth trend, and as one of the accessories of LED lighting, the light guide plate industry has great development space in the global lighting industry chain. With the improvement of social living standards, the demand for lamps in China's prosperous market has also increased, which has continuously promoted the application and development of advanced lamp processing equipment.
With the ever-changing technological development and information needs, today's traditional silk-screen light guides are no longer able to meet the high-quality requirements of LED lamps. Instead, laser-made light guide plates have emerged. So how does this new laser processing method operate? And what processing advantages have become mainstream tools?
Lighting brilliant Zhongshan, processed into a bottleneck of the light guide plate <br> <br> from 1982 to now, after twenty years of national guidance, support, Zhongshan has developed into the largest professional lighting production base and wholesale market. The lighting industry is the industrial leader of Zhongshan Guzhen and the economic pillar.
As we all know, the main body of the LED panel lamp is composed of a light guide plate, a diffuser plate, a reflective film, a light bar light source, etc., and the light guide plate is the most complicated and important part of the whole process. The light efficiency of the light guide plate is the most critical. So, what is a light guide? The light guide plate uses an optical grade acrylic or PC plate, and ink printing or laser spotting on the bottom surface of the plate is used as a light guiding point, and the plate is used to absorb the light emitted from the lamp to stay on the surface of the plate, and when the light hits each light guiding point. At this time, the reflected light is diffused at various angles, and then the reflection reflection condition is emitted from the front surface of the light guide plate. The better the light-emitting efficiency of the light guide plate, the higher the quality of the LED panel light produced, and the more brilliant the development of the enterprise market.
However, despite the rapid development of flat-panel lights in 2013, the development in 2014 is not as good as the expectations, and the overall situation is sluggish. The main reason is that the traditional printed light guide plate technology can not meet the development needs of the technology era, and lacks the professionals who are familiar with the new technology laser marking light guide plate. Therefore, it is not difficult to see that although Zhongshan has a long history of lighting development, how to improve production methods to meet market demand in the future is still a big problem.
Traditional screen printing technology behind the laser dot light guide plate early Xian Shuguang <br> <br> Today, the traditional silk screen dot design technology is very mature, the effect on the brightness and uniformity of the past by a number of customers, and its low cost price . With this advantage, it has an important position in the light guide plate processing market. However, with the development of the times, especially in the recent years when laser equipment is widely popular in the market, the processing methods of screen printing dots have gradually been eliminated, and replaced by advanced light guide laser spotting machines.
First, the process of screen printing a light guide plate is complicated. The acrylic sheet needs to be printed on the screen and ink, and then the board is dried by a screen printing tunnel furnace to form a grid point light guide plate. Among them, the production time of the stencil is long, usually takes one week, and each step requires manual operation. Second, the environment is polluted. Ink is required for the production of silk screen light guide plates, but ink is the largest source of pollution in the printing industry. Because it is an organic volatile substance, it will form oxides and photochemical smog under the sunlight, and the taste is particularly strong and pungent. Long-term work may affect people's health. Third, it is easy to yellow and has a short life. Since the heat generated by the LED during the illumination process will affect the ink, the ink dot will affect the emission of the light, and thus the light decay phenomenon will eventually lead to uneven or yellow light of the LED panel light, and the use time is not long.
Through the above, we can clearly know that the silk screen light guide plate can not meet the development needs of the market, and a new type of processing method is urgently needed to promote the development of the industry. Laser is another major invention of human beings after atomic energy, computers and semiconductors. It is called "the fastest knife", "the most accurate ruler" and "the brightest light". Lasers have been widely used in various industries, and the use of laser equipment in the industrial processing industry has become mainstream. For example, clothing fabric cutting, packaging and marking industry marking, crafts exquisite carving, etc., laser equipment can be perfectly processed. Therefore, we also have reason to believe that advanced laser equipment can bring bright light to the light guide processing industry and the lighting manufacturing industry.

future scientific development, social progress, only hot pursuit pace of the times, in order to better create value for the enterprise, certain to win in the market. As we all know, the rapid development of laser equipment has helped the LED lighting industry to embark on a new level. There are several reasons why the laser spotting machine of the light guide plate has advantages over the conventional silk screen dot light guide plate. First, the laser dot light guide plate reduces the use cost and reduces environmental pollution by eliminating the need for consumables such as ink. Secondly, in the lighting effect, the laser spot light guide plate is not easy to yellow for a long time, the light effect is good, the effect is long, and the life is long. Finally, the use of laser equipment processing can optimize the production of human resources, without the need for a large number of manual operations, as long as through professional training, one can skillfully use the equipment instead of multi-person multi-process silk screen management, greatly improving production efficiency and saving Labor costs. Therefore, the light guide plate laser dot punching machine becomes the best processing method after the silk screen printing process.
