Talking about design from a design perspective and talking about lighting from a building perspective may be the angle that many teachers choose. If we want to talk more deeply? Is there any angle that will allow us to slap the top? Mr. Hu Guojian’s curriculum has opened up a new path. From the perspective of his research, he talks about lighting design, how light is accepted by the optic nerve, and finally forms our emotions. The angle is unique and unique, like a unique martial arts kung fu but mysterious Master. “In the strict sense, we are not designing illumination, but the brightness of different elevations in each space.†When we discuss the lighting scheme, we have a lot to say about the degree of comfort of the perception, but this is only the surface of knowing it, but to know why, you must not miss the course of visual perception research. Too many knowledge hidden secrets may make you suddenly open and realize. 　 Take the curved dome of a metal surface as an example. picture? Said me? Oh, the local is similar. Just as some students asked in the classroom: What should be the photo of the curved dome on the titanium surface? The core of the problem he encountered can be simply summarized as: the curved dome of the titanium surface is relatively high due to the high reflectivity of the material, and the entire curved dome becomes extremely difficult, how to break it? From a technical point of view, everyone can make up for it. Because of the high reflectivity of metal materials, it is difficult to illuminate. What kind of situation is this? Figure: The same curved shape (spherical surface), the left picture shows a smooth surface specular reflection, and the right picture shows a rough diffuse reflection. Under the same light, the rougher the surface, the more obvious the diffuse reflection, and the brightness that can be seen in each direction. The more obvious.
Absolute rotary Encoder measure actual position by generating unique digital codes or bits (instead of pulses) that represent the encoder`s actual position. Single turn absolute encoders output codes that are repeated every full revolution and do not output data to indicate how many revolutions have been made. Multi-turn absolute encoders output a unique code for each shaft position through every rotation, up to 4096 revolutions. Unlike incremental encoders, absolute encoders will retain correct position even if power fails without homing at startup.
