Description

Automatic-closing lamp

Technical Field

The invention relates to the technical field of lighting, in particular to a lamp capable of being automatically turned off.

Background

Lamps are common tools for people in daily life, and the lamps can be various, such as table lamps, ceiling lamps, wall lamps, induction lamps and the like. At present, most lamps can be turned off only by manual operation, and if people forget to turn off the lamps after leaving, the power supply is wasted and unnecessary loss of the lamps is caused.

To address this problem, the prior art provides a bluetooth solution and an infrared sensing solution;

bluetooth solutions automatically turn off the light fixtures when the bluetooth detects the owner's departure after the owner has left, but because the distance detectable by the bluetooth is too far, the light fixtures may not turn off even when the owner has entered another room, which may have been too far from the light fixtures.

The infrared induction solution is greatly influenced by the working environment, and the accuracy of the inductor is influenced if the indoor light is too strong. The color of the clothes worn by the person to be measured has great influence, and the measurement cannot be carried out if the person wears black clothes. The measurement angle is too small, and the object may be lost if the sitting posture of the person to be measured changes. Whether the surface of the measured object is flat or not also influences the measurement. The automatic turn-off lamp based on the infrared switch is very tedious and limits the movement of the tested personnel.
