Abstract: A lighting apparatus includes a base plate, a driver module, a light source, a mechanical switch, a main housing, and a manual switch. The driver module is disposed on a top surface of the base plate. The light source is also disposed on the top surface of the base plate. The mechanical switch is disposed on the base plate. The mechanical switch has multiple states to be selected. The driver reads a selected state to control the light source. The main housing encloses the base plate. The manual switch is disposed on the main housing. An operating part of the manual switch is exposed outside the main housing to be operated by a user. When a user moves the operating part of the manual switch, the connecting part of the manual switch carries the mechanical switch to change the selected state.

Abstract: A human tumble detecting and alarming device includes an external shell body, a sensor module for detecting body postures of an object to be detected in real time, a data processing module for analyzing information detected by the sensor module and judging whether the detected object tumbles or not according to analyzing results, a wireless communicating module connected to the data processing module and a power source module for respectively supplying the sensor module, the data processing module and the wireless communicating module with electricity. The sensor module is a triaxial acceleration sensor. The sensor module, the data processing module, the wireless communicating module and the power source module are all provided within the external shell body. The human tumble detecting and alarming device is simple in structure, small-sized, portable and easy to operate.
