Light guide plate is the standard of good or bad quality of linear light fixture
May 20, 2022
As technology continues to improve, the cost of LED production at a rate of 30% per year. Industry insiders believe that the total phase-out of incandescent lamps will not be more than 10 years. In order to make the healthy and orderly development of the LED lighting industry, a number of experts suggested that the strengthening of the national guidance for the overall local LED industry planning, as soon as possible to introduce enforceable national industry standards, especially in demonstration projects related to product industry standards, such as street lights, tunnel lights, displays, landscape lights, etc., so that government procurement and enterprises around the provision of products have standards to follow.
Expanding market demand will promote rapid technological progress, and national support for LED will be the icing on the cake for the development of this lighting industry.
Three-dimensional dynamic focus carving width, fast and suitable for different thickness of the processing material
A variety of processing methods in one: mesh, bitmap, scribing, cutting once completed line light guide plate
Light guide plate is the key point of quality control of led line lights, the dot design is not good, the overall light effect is poor, the light is not uniform, there will be a bright middle and dark sides, into the light at the bright band, visible local dark areas, different angles of brightness inconsistency and so on. To improve the light effect of the guide plate mainly depends on the design of the network, followed by the quality of the plate, it is desirable to choose a high light transmission rate of qualified plate.
Light guide plate is a new development in the 21st century, a line light source into a surface light source of high-tech products, the dot forming method is divided into printing and non-printing, printing is mainly inkjet printing, non-printing is divided into chemical etching, precision mechanical scribing method, laser dotting, etc.. So what are the advantages of laser dotting of light guide plate compared with ink printing?
Processing range up to 1.5M×1.5M
With the continuous progress of the production technology of light guide plate, there is a new type of laser dotting machine engraved light guide plate. The emergence of laser light guide plate is not only a crystallization of technology, but also the gospel of light guide plate manufacturers.
With the continuous growth of production, life, city streets and other lighting, lighting electricity consumption in the power consumption of the increasingly prominent position. According to China International Lighting Network statistics, China's lighting electricity accounts for more than 12% of the total national electricity consumption, and at an average annual rate of 15% increase. As a substitute for incandescent lamps, the market for energy-saving lighting products is ushering in a good opportunity.
Other parameters Working power supply 220V / 50Hz /7KVA
The design principle of the light guide plate is derived from the LCD screen of notebook computers, which is a high-tech product that transforms the line light source into a surface light source. Optical grade acrylic (PMMA) / PC as the substrate, the use of LCD display and laptop backlight module technology, through the high light transmission rate of the light guide point, the computer calculation of the light guide point, so that the light guide plate light refraction into a surface light source even light state manufacturing molding. The product adopts the combination of spectral analysis principle and digital UV printing technology and is made under constant temperature, humidity and dust-free environment. With ultra-thin, ultra-bright, light uniformity, energy saving, environmental protection, no dark areas, durable, not easy to yellowing, installation and maintenance is simple and fast and other distinctive features
"If we do not regulate the market, the future will likely be reduced to the point of doing the dowry for foreign lighting giants." Jiang Fengyi said.
Dot size and dot pitch can be automatically gradual change
Optical PMMA sheet is divided into single film and multi-film, the general optical PMMA sheet is only a single film, it is made into a backlight board to add a lot of reflective or diffusion film to prevent light out. Multi-film optical PMMA sheet means that the refractive index of both sides is greater than the refractive index of the middle layer, so that the light can't break out of the surface layer, like optical fiber to allow light transmission. Light in the multi-film optical grade PMMA plate is geometric waveguide forward, to change the way of light transmission also need to add high refractive index of transparent PMMA micron material, in order to make the light to produce effective control of uniformity.
Many experts believe that the market competition is becoming increasingly fierce, strengthen the next generation of semiconductor lighting technology research and development work can not wait. At the same time, the early realization of the core equipment of semiconductor lighting MOCVD localization, fundamentally change the situation of high-end equipment subject to human, to promote the rapid, healthy and sustainable development of China's strategic emerging industries of semiconductor lighting.
Now do design generally require line lighting source in addition to color changes, but also color temperature changes. The more light source changes, the richer my performance. At present, the domestic line light RGB color purity are relatively poor, giving the feeling of dirty color. Students with high requirements for color need to pay attention to this point.
