Sunrise LED has been in operation for more than 10 years since 2007, and has become one of the leading manufacturers of LED display. Sunrise 2016 was listed in Shanghai Property Exchange Center with the stock number 668192.In 5000 square meters of 5S anti-static dust workshop, sunrise has six production lines, can produce more than 1000 square meters of LED display every month. In order to get high quality products, sunrise has a complete set of machinery and equipment, including professional SMT. Japan, all kinds of testing equipment, automatic silicon feeder, vibration testing equipment, standard waterproof laboratory. Every customer wants to purchase high-quality indoor LED display signs. The use of inferior LED beads, not only affects the display effect, but also greatly reduces the life of the display screen, and even easy to appear dead lights, color difference and other issues. Therefore, high quality indoor LED display signs must be the use of high quality LED beads display screen, then distinguish the advantages and disadvantages of the beads has become a very important work. Next, Sun Eleddisplay (www.sunriseleddisplay.com) tells you six ways to differentiate between good and bad lights. indoor led display signs Beads are the most important components of indoor LED display signs, and also the most used core devices, which directly affect the use of LED display effects. Thousands of LED beads are used for each square meter of indoor LED display. For example, the indoor small-spacing LED display P1.5625 uses as many as 409,600 beads per square meter. The proportion of lamp beads in the overall cost of indoor LED display signs is the largest, ranging from 40% to 70%. Every customer wants to purchase high-quality indoor LED display signs. The use of inferior LED beads, not only affects the display effect, but also greatly reduces the life of the display screen, and even easy to appear dead lights, color difference and other issues. Therefore, high quality indoor LED display signs must be the use of high quality LED beads display screen, then distinguish the advantages and disadvantages of the beads has become a very important work. Next, Sun Eleddisplay (www.sunriseleddisplay.com) tells you six ways to differentiate between good and bad lights. indoor led display signs First, look at the size of chips and chips, and chips are the deciding factors for the quality of lamp beads. Generally speaking, the larger the chip, the stronger the stability. The higher the brightness, the better the heat dissipation. This is the most important, because the chip directly determines the color rendering index, brightness, and degree of attenuation. Two, look at the brightness. How many LM can your lamp bead reach (Liu Ming) and LM (Liu Ming) is the unit to measure the brightness of the lamp. Three, see whether the luminescence is uniform and whether the color is consistent. Good quality bulbs are evenly distributed with uniform color. The poor quality of the lamp beads will appear a bright, a dark phenomenon of the lamp beads, the color of light is disorderly, there will be a clear dark area. Four, look at the bracket. Generally speaking, the bracket is silver-plated brass bracket. The advantage of silver-plated brass bracket is that it can dissipate heat more quickly, and it can better dissipate heat to the lamp beads with less resistance. Ceramic scaffolds, which have excellent thermal conductivity, will replace silver-plated red copper scaffolds in the market. Five, look at the glue. Generally good bulbs will use imported glue, good LED beads packaged by hand without deformation, inexpensive glue on a press will appear deformation or even cracking phenomenon. Sixth, look at the packaging process. The LED beads with good quality are uniform in color and good consistency in colloid. This is inseparable from good machinery and equipment, the production of machinery and equipment is a key factor, good equipment can ensure the stability and consistency of the product in various procedures, to ensure the product yield. Master the above six methods, easy to solve the indoor LED display sign beads quality identification problem, so that you can buy high-quality and assured LED display products.
