Technical Field

[0001] The present invention belongs to the technical field of LED downlights, and in particular relates to an LED downlight with adjustable light emitting angle, color temperature and power and a realization method thereof. Background Art

[0002] With the progress of society, LED lighting has gradually become the mainstream in the field of indoor lighting. Among them, LED downlights have the characteristics of focusing, high light efficiency, and low energy consumption, and are deeply loved by consumers in the home lighting market.

[0003] The mainstream downlights on the market are basically traditional single-color or three-color temperature non-adjustable lighting modes. Although the products are rich, the functions are single and the experience is poor. At present, LED downlights mainly use lenses to meet the luminous angle requirements of the whole lamp, and the luminous angle cannot be switched. The DIP switch that can switch the color temperature and power is usually installed on the heat dissipation housing on the back of the downlight, or on an external driver box. There are some problems in the use process, such as:

[0004] 1. When you want to toggle the switch to switch the lighting mode, you need to remove the downlight, which is very easy to damage the downlight and the installation surface, affecting the appearance.

[0005] 2. It does not have the function of adjusting color temperature and cannot provide customers with more choices.

[0006] In addition, the face ring of the downlight after installation is single and cannot be replaced. Summary of the invention
