Technical Field
[0001] This utility model relates to a lighting device, and more particularly to a centralized control and light decay compensation catering lighting device. Background Technology
[0002] In existing technologies, most lighting devices are intelligent control systems, which typically employ complex circuit structures to control the light source, resulting in problems such as cumbersome maintenance and high costs. Furthermore, with increasing usage time, the light output of the light source gradually weakens (i.e., light decay), affecting lighting performance and lifespan. Therefore, a new type of lighting device is needed to solve these problems.
[0003] In view of this, the inventor has specifically developed a centralized control and light decay compensation catering lighting device, which leads to this invention. Utility Model Content

The electromagnetic compatibility module is sequentially connected to the bridge rectifier circuit module, the buck current-limiting drive circuit module, the power conversion module, the light source module, and the light attenuation compensation module. The controller is connected to both the low-voltage switching power supply module and the buck current-limiting drive circuit module. The low-voltage switching power supply module is connected to the bridge rectifier circuit module.

[0012] Second, by combining the step-down current limiting drive circuit module and the light attenuation compensation module, the working current and voltage of the light source can be precisely controlled to avoid overload and voltage fluctuations, thereby extending the service life of the light source. The first DC48-96V output module and the second DC48-96V output module of the power conversion module can provide stable power output and reduce the light attenuation problem caused by power fluctuations.
[0013] Third, the electromagnetic compatibility module reduces the electromagnetic interference of the lighting device to other electronic devices, while also improving the device's own resistance to electromagnetic interference.
