Embodiment Construction
[0065] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0066] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

The invention relates to a microwave sensing dimming circuit with an emergency mode. When an interface voltage detection module detects a low voltage, time keeping begins, and then whether a lamp needs to enter an emergency mode or not is judged; if the lamp needs to enter the emergency mode, a microwave sensing module is closed; if the lamp does not need to enter the emergency mode, the microwave sensing module begins to work, and the lamp luminance is controlled according to whether there is human body movement or not; when there is a human body, the microwave sensing module, by combination with the interface voltage module, a dial switch module and a signal processing module, enables the lamp to be in the highest luminance; and if there is no human body, the microwave sensing module, by combination with the interface voltage module, the dial switch module and the signal processing module, enables the lamp to be in the lowest luminance. Therefore, the lamp has the emergency function; and in addition, the lamp luminance can be adjusted in a microwave sensing state, so that convenience is brought to use of a user. In addition, the invention also provides the lamp.
Description
technical field [0001] The invention relates to a microwave induction circuit, in particular to a microwave induction dimming circuit with an emergency mode capable of adjusting the brightness of a lamp and a lamp. Background technique [0002] In areas requiring long-term lighting such as hydropower plant corridors, cable tunnels, manufacturing pits of large enterprises, aisles, and power industries, 1-10V dimmable LED lamps are required. When the staff regularly inspects and works, the LEDs are all on, and when there is no one, it is required to output a weak light. The output of the traditional microwave sensor module is TTL level, which is not compatible with the 1-10V dimming interface. At the same time, the user cannot adjust the brightness of the lamp when no one is present according to the actual needs. Contents of the invention [0003] Based on this, there is a need for a microwave induction dimming circuit with an emergency mode that can adjust the brightness o...
