Embodiment 1

[0015] Embodiment 1, reference figure 1 and figure 2 , one An automatic induction wall lamp, comprising a lamp body, the lamp body includes a base b1, a lampshade, a lamp arm b2, and a light source, the light source is located inside the lampshade, and the lampshade is connected to the base b1 through the lamp arm b2 connection; the lamp arm b2 is made of aluminum alloy components, and the weight of the entire wall lamp is reduced under the premise of ensuring strength; as an optimization, the lampshade includes an inner cover b4 and an outer cover b3, and the light source is installed in the inner cover b4. The lampshade is divided into an inner cover b4 and an outer cover b3 to facilitate heat insulation of the wall lamp. Further, a heat insulating coating is provided on the inner side of the outer cover b3, which can improve the heat insulation efficiency of the outer cover b3;

[0016] The lamp body is provided with a microwave automatic switch circuit, and the microw...

Abstract

The invention discloses an auto-induction wall lamp. The auto-induction wall lamp comprises a lamp body. A luminous source is arranged in the lamp body, and a microwave automatic switching circuit is arranged in the lamp body. A microwave electromagnetic field is formed nearby the wall lamp by utilizing the microwave automatic switching circuit, according to the doppler effect, when people walk nearby the wall lamp, frequency shift occurs in the microwave electromagnetic field nearby the wall lamp, and when nobody walks nearby the wall lamp, frequency shift does not occur in the microwave electromagnetic field nearby the wall lamp. According to the principle, through cooperation of an amplifying circuit, a comparison circuit and a driving circuit, a frequency-shifting or non-frequency-shifting signal is converted into a lighting-extinguishing action of the luminous source. Because a circuit connecting structure does not need to detect an infrared signal of people, the possibility of wall lamp false triggering caused by light pollution is completely eradicated, and the problem that a present induction wall lamp is prone to being triggered falsely is solved.

Description

technical field [0001] The invention relates to the technical field of lamps, in particular to an automatic induction wall lamp. Background technique [0002] At present, wall lamps are installed on indoor walls for auxiliary lighting and decorative lamps. Most of them are installed on balconies, stairs, corridors and bedrooms; When people leave the sensor wall light, the wall light goes out. [0003] However, the current induction wall lamps have a common problem, that is, they are easy to be triggered by mistake. Even when no one is approaching, the wall lamp will automatically light up. The reason is that the sensor used by the induction wall lamp to sense the human body is a pyroelectric infrared sensor. The sensor can respond to human infrared signals. However, due to the serious light pollution in today's society, the pyroelectric infrared sensor is easily interfered by external infrared light sources, which makes the sensor wall lamp falsely triggered.
