Description

Technical Field

[0001] This application relates to the technical field of circuit boards, and particularly to an automatically sensing circuit board. Background Art

[0002] A circuit board, short for a printed circuit board, is a support for electronic components and also a provider of electrical connections for electronic components. Most of its substrates are made of aluminum substrates with good heat dissipation. Circuit boards are widely used in various electrical appliances, such as small lighting night lights. As a simple lighting product, night lights have various structures. Generally, they include a housing and a circuit board and a lamp board arranged inside the housing. Currently, small night lights on the market have various functions, such as adding a solar panel or setting up a sensing device, which can automatically sense the ambient light and turn on and off, saving energy and being environmentally friendly.

[0003] The existing sensing small night lights have a simple structure. They only detect the ambient brightness through a light sensor and control the lamp board to emit light or turn off. However, when used indoors, false alarms may occur when it is cloudy or the doors and windows are closed and the indoor environment is relatively dark, resulting in the lamp board emitting light. At the same time, the night light will also emit light when there is no one in the room at night, resulting in waste of electricity. Most of the circuit boards of current sensing small night lights are fixed by bolt connection, which has the problem of inconvenient installation. Therefore, it is necessary to design an automatically sensing circuit board that is convenient to install and saves electricity. Utility Model Content
