Sensor switch device and lamp using same

Abstract

Provided are a sensor switch device and a lamp using the same. The lamp comprises a load, a sensor switch device for controlling the load to be on and off, and an AC power source for providing power. The sensor switch device comprises a sense module, a switch module, a signal detection module, a signal processing module, and a signal time-delay module. If the signal processing module receives a switch signal output from the sense module, the signal detection module is triggered by the signal processing module to detect an input voltage, and a detection signal is output to the time-delay module if the input voltage is higher than a preset value. The time-delay module performs time-delay processing on the basis of the output detection signal, and the signal processing module enables the switch module to be on and off when an input current is lower than a peak current of the switch module. The lamp can be turned on within a relatively safe voltage range, the intensity of impact currents acting on components and the load is reduced, and the interference is minimized.

Description

technical field [0001] The invention relates to a lighting device, in particular to a lamp with an inductive switch device. Background technique [0002] With the continuous development of home and commercial lighting industries, various humanized intelligent lamps can be applied in various lighting occasions, and lamps with sensor switch devices are a kind of lighting equipment that can be switched automatically. When the human body enters the sensing range of the sensor of the inductive switch device, the change of the infrared spectrum caused by the human body is converted into an electrical signal, so that the inductive switch device turns on the load of the lamp. And when the human body leaves, the inductive switch device will turn off the load. The lamp with the induction switch device realizes the function of automatic switch, which not only brings excellent lighting experience to people, but also saves energy. But when the instant on and off function of the lamp wi...

AI Technical Summary

Problems solved by technology

The moment of turning on or off of the lamp is random, so the lamp is easy to turn on or off at a higher input voltage value

When the lamp is turned on at a high voltage value, it is easy to generate a large inrush current, causing impact damage to the load and the circuit

And when the lamp is turned off at a high voltage value, the switching element is easy to flash over and trigger by mistake so that the induction switch device is turned on again.
