Self-starting mini night light

Abstract

The invention discloses a self-starting small night lamp, which comprises the following parts: AC-DC conversion circuit, self-starting circuit and lamp holder, wherein the self-starting circuit contains reference circuit and photoinduction circuit; the reference circuit parallels the output end of AC-DC conversion circuit; the photoinduction circuit contains at least series electric connection fixation resistance and light-sensitive resistance, whose electric connection point cascades LED with reference point of reference circuit; one end of fixation resistance connects the DC output positive pole of AC-DC conversion circuit in the light-sensitive circuit; the other end of light-sensitive resistance connects the DC output negative pole of AC-DC conversion circuit in the light-sensitive circuit; when the light is dark, the self-starting small night lamp will start automatically; when the light is bright, it will close automatically. The invention can be fixed at the needed position without adding power wiring board.

Description

Technical field: [0001] The invention relates to a small night light, in particular to a self-starting small night light. Background technique: [0002] Night lights are generally dark, and are often used in environments where children and the elderly need to be taken care of at night. When it is turned on, on the one hand, you can see things in the room clearly, and it will not affect other people's rest. Yet night light all is to control the opening of light by manual switch, turns on every day at night, and turns off power supply when dawn. Due to the cheap price of the night light, the switch quality of most night lights is average, and frequent use will damage the switch, so that the night light cannot be turned on or off. Most of these night lights are filled with inert gas neon tubes, which are extremely easy to damage. [0003] In addition, the night light is usually used for the convenience of the elderly or taking care of children. It is fixed at a position wher...

Problems solved by technology

Due to the cheap price of the night light, the switch quality of most night lights is average, and frequent use will damage the switch, so that the night light cannot be turned on or off

Most of these night lights use neon tubes injected with inert gas, which are extremely easy to damage.

[0003] In addition, the night light is usually used for the convenience of the elderly or taking care of children. It is fixed at a position where people can easily reach out. However, the existing night lights have their own plugs. Generally, an additional power connection is required. board, the power wiring board is fixed to a position that is easy to reach by hand, which brings inconvenience to use
