Since the appearance of LED lights, it has been used in indoor areas such as hotel lighting, commercial lighting, and home lighting. In the past few years, outdoor landscape lighting has been hot. Due to the low barriers to entry of LED lights, a large number of enterprises have been engaged in the production of LED light strips. These lights have also been applied to landscape lighting, but due to product quality and technical issues, Many projects have “fallen and slammed”, so that it is rare to see LED lights on a large scale for outdoor buildings.
At present, from the market point of view, most of the lamp belt products are PVC and PU lamp belts, and the silicone type lamp belts are mostly hot silicone lamp belts. The lamp strips are all cold silicone lamp strips. The products are divided into positive bending and lateral bending. The characteristics of the cold silicone lamp strip are firstly reflected in the anti-UV and almost immune to the characteristics of UV so that the cold silicone lamp strip solves the problem of yellowing in outdoor applications.
Secondly, the application of the lamp strip in the outdoor must solve the problem of weather resistance. For example, the lap belt should be used in a space environment between -40 ° C and 60 ° C, which is not something that ordinary lamp belts can withstand. Deng Yilin mentioned that in the experiment, the impact of the lamp belt product on the hot and cold cycle, such as the lamp belt placed in the space of -40 ° C for 30 minutes, and instantly switch the temperature to 105 ° C or 60 ° C, so cycle 50 ~ 100 Back and forth, the light strip can still not fail. In addition, they also tried to use 1000 ° C hot to heat the lamp strip, and the lamp strip did not leave a slight trace, and will not melt, and so on a series of extremely harsh reliability experiments.
Furthermore, the structural stability of the cold silicone lamp strip is relatively high, and there is no problem that the general lamp strip is prone to falling off and deformation in outdoor applications. The anti-collision level is also very high, and the lamp belt is based on the IK06 standard, and the IK10 anti-collision level can also be achieved.
Compared with traditional point source luminaires, the use of light strips in outdoor buildings also has some advantages.
First, the installation of the lamp strip is a split structure, and the bottom bracket and the lamp strip are separated, which facilitates the later maintenance. For example, the lamp is broken, the whole lamp does not need to be removed, and only the lamp strip needs to be unplugged. Put on a new light strip. The traditional luminaires need to be disassembled for the entire luminaire, which will cause some damage to the applicable carrier. The light strip product installation aluminum tank has a large internal space, which allows the cable to pass and connect inside. After installation, there is no connecting line on the exterior of the curtain wall, which is beautiful and atmospheric.
Second, the light strip solves the problem of super pressure drop. The voltage drop can reach 16 meters in one direction and up to 20 meters in length. It is equivalent to 4 or 5 floors for one strong power, which greatly reduces the laying of strong and weak wires inside. Deng Yilin said that in the Yangjiang International Financial Center project, there is no strong wire or weak wire on the fa?ade of the entire building. The traditional method of installation is to have a conduit next to the fixture to take the mains or weak points, and they don’t need it. This also greatly reduces the installation and use of wire and cable.
