Because LED's are semiconductor devices, more sensitive to static electricity, especially for white, green, blue, purple LED lamp beads light boxes bus kiosks, so do prevent static electricity and eliminate static work 1. Static electricity generation: Friction: Rolling light boxes in their daily lives, any two objects of different materials in contact after separation to produce static electricity, and produce the most common method of electrostatic double-sided light boxes, it is friction electricity. The better the insulating material, the more likely friction electricity. In addition, any object after the contact of two different substances separated, but also can produce electrostatic induction: For the conductive material, the electron energy due to free-flowing on its surface, as will be placed in an electric field, due to sex repulsion , opposites attract, positive and negative ions will be transferred, will have a charge on its surface. Conduction: For conductive material, because electrons can flow freely on its surface, such as contact with the charged object] Touch light boxes, charge transfer occurs. The company strongly recommends that customers use high-pressure direct 220V light shutter, a plurality of series did not drop wiring, 24V shutter lights, shutter lights (dedicated to Raab boxes, plastic boxes, printing boxes, outdoor light boxes). 220V power side LED lights, high-power side-emitting light bar (dedicated to rolling light boxes, for surface light boxes, bus shelters light boxes, residential light boxes billboards advertising _ far illumination (certification) _ light boxes from far Lighting Technology Co., The company offers Far Lighting Technology Co., Ltd. (www.ygzmkj.com) (www.ygzmkj.com) Shandong Dezhou, advertising lighting leader, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum meet customer needs. In the far lighting leadership with the staff warmly welcome all inquiries negotiations to create a far better future lighting.
