The principle of the photoelectric speed sensor and the acquisition of the speed signal of the installation unit can generally be obtained by attaching a metal foil on the rotating shaft or opening a key phase groove on the rotating shaft, which is generated by the eddy current sensor when it is close to the space of the sheet or the groove. Electrical pulse signal to achieve. The installation of the accelerometer in this system adopts the double-headed steel bolt fixing method. When installing, a high-demand plane and a certain size screw hole are firstly machined on the mounting surface, and the mounting head of the acceleration sensor can be screwed into the screw hole. Whether it is patch or slotting, it will affect the balance of the rotating shaft, and the speed of the unit is high. If the sticking is not strong, it will bring certain danger. In addition, the eddy current sensor needs to be connected to a larger converter, which is expensive. Therefore, this paper adopts the photoelectric speed measurement method, that is, attaching a reflective metal paper on the surface of the rotating shaft. The acceleration sensor is installed in five ways: double-headed steel bolt fixing, insulating bolt fixing, permanent magnet fixing, waxing layer bonding and adhesive fixing. Among them, the double-headed steel bolt-on type is the most ideal installation method. The measured object and the sensor can be regarded as a whole, so the resonance frequency is the highest compared with other methods, and can withstand the maximum acceleration.
We diviided the led light according to the using eviiroment. Most of our product is the commercial LED Lighting
Commercial lighting is a term used to describe lighting that is used in commercial spaces, including auto dealerships, distribution centers, churches, factories, offices, and warehouses. Unlike residential lighting, commercial lighting is made to withstand more abuse and has a longer lifespan.
While the focus of residential lighting is often on aesthetics, commercial lighting is task orientated. Commercial lighting systems are designed based on what the application is. For example, in an office-type setting, you may see task lighting, which illuminates specific areas where employees need concentrated light to be able to perform their jobs.
