led lights, are free to stay on the floor, wall or table, the idea is simple and easy form to convey the experience of visual perception and light, so full of fun and vitality into lamps the life of the body. fourth, no doubt human nature, light and human relations is an eternal topic, "people see the light, i saw the light" is a phrase many classic discourse has changed the understanding of lighting designers. lamps highest state of "shadowless" light is the highest expression of humanity, common room, without any trace of light, so that people can feel but can not find the light source, reflects the perfect combination of light and human nature of human life design. led lamps light the small plot, you can choose different combinations of light and color of led .illuminated signs
most domestic manufacturers of led rails of too little experience, less investment in r & d is also an important factor. this paper will introduce several aspects to the reliability of rails and the solutions to these problems, manufacturers hope to give rails, light engineering company and owners of some valuable reference for. 2. led rails of reliability issues to be resolved before 2.1 waterproof led fence tube is sealed with silicone cover interface, the internal led, the circuit is exposed, the temperature difference between day and night, cover the ends of the thermal expansion and cold housing different shrinkage, resulting in silicone seal a gap, after the rain the rain infiltrated the interior, we can imagine what will happen. to solve this problem, we require the internal circuits and led plastic irrigation treatment, silicone seal the outside cover of course is simple, but the reliability of large-scale than in outdoor applications. another problem is the joint problem of electrical connections.led message display
extension?? research institute, 2008/11 guided three-dimensional hot low thermal resistance led package is received by the united states, lightning itri r & d 100 award for sure the core technology. interface thermal resistance of the international safety standard package is not greater than 3 / w, the use of electro-optical three-dimensional thermal packaging concept, increased thermal contact area 10 times the original, also increased the volume of heat, so that the interface thermal resistance is only 0.3 / w, the most criticized greatly improved led heat problem. integrated circuits and heat dissipation due to the package inside, also with a plug-like appearance, can be directly replaced in the general use of the ac socket, adding convenience. figure four three-dimensional thermal packaging technology patent source: itri eol; extension?? .led message displays
