【Background technique】

Lamps with emergency lighting functions are generally used in crowded public places to provide emergency lighting for evacuation and firefighting operations. In addition, downlights are widely used in various lighting places. If the downlight also has an emergency lighting function, the functions of the emergency lighting fixture and the downlight can be combined into one, so that there is no need to install multiple lights in the same place. lamp species. At present, the LED downlights on the market do not have the emergency lighting function. If there is a sudden power failure, the downlights cannot continue to work.

Downlight is a kind of lighting fixture that is embedded in the ceiling and emits light. It is used in a large amount in engineering construction. It has a wide range of uses and is used in shopping malls, specialty stores, office buildings, and home decoration. Its biggest feature is that it can maintain the overall unity and perfection of architectural decoration, and will not destroy the perfect unity of ceiling art because of the setting of lamps.

However, when installing a downlight, there will always be times when the diameter of the ceiling opening is larger than that of the downlight, especially when the original ceiling is remodeled. One method is to remove the original ceiling and reinstall it; the second method is to replace the downlight with the same diameter as the original ceiling opening; the third method is to seal the ceiling opening and then open Suitable for ceiling holes as required.

All three methods have weaknesses. In the first method, although reinstallation will make the overall appearance beautiful, the cost is high and time-consuming is long. The second method, although it will make the overall appearance beautiful, increases the purchase cost of the downlight, and also runs counter to the original design concept; the third method is the lowest cost one, but the plugging requires a professional There are many personnel to operate, and the steps are numerous and time-consuming.

Moreover, most downlights on the market are assembled with screws, which not only requires a lot of assembly processes, but also requires different screw specifications, which easily leads to confusion in use and high production costs.
