Description

A smart LED light tube that supports Mesh networking and positioning

Technical field

The utility model relates to the field of smart lighting, and in particular to an intelligent LED lamp that supports Mesh networking and positioning.

Background technique

In public areas where people are concentrated, LED lamps are often used for lighting. These places have a significant "tide" phenomenon, that is, people or vehicles will be concentrated during certain periods, while there will be fewer people or vehicles during other periods. If the same lighting strategy is adopted at all times, it will cause a lot of ineffective lighting, resulting in serious waste of electricity, such as underground garages, warehouses, subway stations, etc. However, existing energy-saving lighting measures often only use a single sensor to control lighting brightness. For example, an infrared sensor keeps the brightness low at ordinary times, and then increases the brightness when someone is detected. The result of this is that the person is moving in the direction of travel. It's dark and only lights up when you get under the lamp, which is a very bad experience.

Therefore, in these public areas, if the lights can be connected to the Internet and communicate with each other when no one is around, forming a group of linked lights, this will not only effectively save energy, but also provide the "lights turn on before people arrive" "Good experience. On this basis, adding positioning function can realize more intelligent scenarios.

In order to achieve the above purpose, an intelligent LED lamp that supports Mesh networking and positioning is proposed.
