[0002] With the improvement of people's living standards, the requirements for lighting equipment are no longer limited to simple lighting functions, but more intelligent and personalized lighting experiences are pursued. Traditional lighting lamps have many shortcomings in terms of lighting effect, energy utilization, and maintenance convenience.
[0003] On the one hand, traditional lamps can usually only provide overall lighting and cannot achieve precise lighting control of specific areas, which leads to waste of energy utilization and cannot meet user needs in some local lighting scenarios. For example, in a home environment, when a user only wants to be active in a certain area of the living room, the traditional lamp cannot only illuminate that area but must illuminate the entire living room space, which not only increases power consumption but also may cause light pollution and affect the normal use of other areas. On the other hand, the internal structure of traditional lamps is often complex, and the replacement and maintenance of key components such as light bulbs are difficult. Once the lamp fails, it often needs to be disassembled and repaired by professional personnel, which brings many inconveniences to users.
[0004] In addition, the lamps on the market are relatively single in lighting mode, lack flexibility and diversity, and cannot be customized according to different user needs and scene changes. In some commercial places or special lighting scenarios such as museums and art galleries, precise lighting is required according to different exhibits or areas, and traditional lamps cannot achieve such fine lighting control.
[0005] In order to overcome the above-mentioned defects of traditional lighting lamps and meet the needs of modern people for intelligent, personalized, and energy-efficient lighting equipment, it is particularly important to design an intelligent lighting device.
