Landscape lighting is an emerging market in the field of LED lighting. It is also the most mature branch of LED in the field of lighting. LED has successfully occupied a series of advantages such as high efficiency, low energy consumption, safety and reliability, convenient management and outstanding social and economic benefits. Absolute market share in landscape lighting.
He Zaihua, a senior researcher at China Investment Consulting, pointed out that just because the development speed of China's lighting market is very fast, the development of LED in the field of landscape lighting has been expanded and gradually matured. In 2007, 90% of the lighting projects in Wuhan City adopted LED-based energy-saving materials. The Olympic Water Cube, Expo and Asian Games all made LEDs shine in front of the audience. For a time, LED scenery did not shine. To compare.
Although LED has been used quite mature in the field of landscape lighting, it also exposes some problems. If night lighting exceeds a certain control range, it will produce light pollution. The domestic comparison wind is becoming more and more popular. Therefore, in the whole landscape lighting planning. In order to pursue high brightness, unlimited use of LED lighting products, or for the holiday effect to ignore the usual lighting effects, the original is reversed, resulting in undesirable social effects.
According to the “2010-2015 China Semiconductor Lighting (LED) Industry Investment Analysis and Forecast Report†released by China Investment Consulting, the use of LED lighting instead of traditional neon lights can save 60% to 70% of electricity, in all major and medium-sized cities in China. The lighting project in the tourist area is gradually being replaced by LED lighting. With the increasing demand for energy saving and emission reduction, the control of electric energy will become more and more prominent, which will give us more room for development in the field of lighting.
Zhang Yulin, research director of China Investment Consulting, pointed out that landscape lighting requires a great deal of coordination and cooperation between architects and lighting designers. However, cooperation at this stage often does not enter a deeper stage, but focuses on the effect, without examining the inherent quality, serious It affects the coordination of LED lighting, and the phenomenon of mutual imitation is very prominent, and the same is the biggest failure. Therefore, the application of LED in the field of landscape lighting should promote innovation and characteristics, so as to promote the progress of the industry.
Progressive Punching is an efficient self-riveting process of fixed rotor, which can realize large-scale and precise riveting operation and is suitable for mass manufacturing production line. The following is the introduction of progressive rotor self-riveting process:
First, determine the type and specification of the stator and rotor required for riveting, and prepare the rivets and riveting machines required for riveting. Rivet size should match the hole size of stator and rotor to ensure tight fit and firmness.
According to the size and riveting requirements of stator and rotor, the rivet is machined into the corresponding length and shape. Progressive punch riveting machine also needs to adjust, set, calibrate the position of the riveting head, pressure, speed and other parameters.
Insert the rivet into the stator hole, and start the progressive punching riveting machine with electricity. The rivet will exert force on the rivet head according to the set parameters, and form a large number of threaded processes on the inner wall of the stator hole, so that the rivet deformation is firmly connected with the stator.
Wait for the rivet deformation, riveting process is complete. The remaining rivet tail should be cut off and inspected after riveting is completed to ensure that the riveting is firm and reliable and the transmission system runs smoothly.
In general, the process of progressive impact fixed rotor self-riveting can improve the production efficiency, but also ensure the precision and stability of riveting. However, riveting machine adjustment requires specialized skills, so an operator familiar with the riveting process is required.
