What if we approach it from the perspective of lighting design?

　　Let me briefly tell you the stories about the design of dark trough lighting.

　　When I designed the halogen bulb version, the compact energy-saving lamp version, and the T5 fluorescent tube version (with a red, green, and blue color temperature change version), I collected a 10CM high collection of information. Of course, I also applied for several U.S. work-related invention patents.

　　Let me briefly talk about some of the key points designed at that time.

　　1. For different markets, the conventional sizes of local decoration light troughs should be clarified first, and the most common ones should be selected as the design standard. Otherwise, there will be such stupid problems as the shading lines are too close.

　　After the lamp is designed, the specification sheet should tell people: How should the decoration company design the lamp trough for my lamp so that there will be no problems?

　　2. Dark areas, the lamps should be designed with a special rotating joint, so that the lamps can be staggered to avoid dark areas along the length. (Well, later there was a T5 bracket, the glass part of the light tube was made into a long π shape to avoid dark areas, there are various methods)

　　3. Some versions require special reflectors to evenly distribute the light to the ceiling, covering a larger area.

　　4. Adding a diffusion cover on the matte surface of the reflector or the light source can help to create the effect of seeing the light source on the floor due to the mirror reflection of the ceiling in some applications.

　　5. Some reflectors have adjustable angles, and the lamps should also have adjustable brackets to cope with the impact of unusual lamp troughs.

The article has already mentioned the problems that occur during the use of 　　current LED soft and hard light strips. I would like to add:

　　1. Tell people the specifications of the light troughs you are going to use! For a fait accompli, the simplest way is to design the installation position of the light strip in the AutoCAD drawing when designing the lighting, and to facilitate monitoring, design a wooden strip at the bottom of the light strip (why wooden strip? Brother, it’s cheap, and there are so many decoration companies). Sometimes, the wooden strip can be tilted at an angle. Let the decoration company install the wooden strip design, as they are more professional in the location and size.

　　Then the electrician can just stick the light strips on the wooden strips. Otherwise, you might as well expect a hen to lay duck eggs if you expect the electrician to stick the light strips on the designated positions. Well, I didn't want to say this originally. The furniture factory paid me to design this for them.

　　Classroom Master interjected: On-site construction... Can you make a special wooden strip according to the drawings? Unless you personally watch him do it on site, it's almost the same ~ a more reliable method is for the manufacturer to directly produce an angled installation clip.

　　2. Now some professional light strips have aluminum extrusion brackets or simple mounting brackets, which are actually variants of T5-like brackets. This is the development direction of the segmented market, which can avoid the fierce price war of T5 brackets, soft and hard light strips. However, there are currently insufficient segmented solutions for such products, and they lack professionalism, so there is a lot of room for development. You can refer to the design principles of traditional dark trough lamps to launch LED commercial versions. I won’t go into details. If I write in detail, it will become a design specification.

　　3. If you have the ability, for certain laces, such as wooden lace and plaster lace, ask them to leave you a recommended small groove so that you can make customized light strips.

　　I won’t tell you: someone has already made it. Did any of you see this at the Frankfurt Exhibition last year?
