Abstract

The embodiment of the invention provides an LED explosion-proof induction lamp, a control method and an intrinsic safety type driving power source device. The LED explosion-proof induction lamp comprises an LED control panel, an LED light source and a pyroelectric infrared induction probe; the LED control panel and the LED light source are located in an explosion-proof shell, and the LED control panel comprises a driving power switch circuit, an intrinsic safety power supply circuit and an induction signal processing circuit; the intrinsic safety power supply circuit is used for providing voltage required by the circuit for the pyroelectric infrared induction probe; the pyroelectric infrared induction probe is used for generating a human body induction trigger signal when detecting that a human body exists in a preset distance range; the induction signal processing circuit is used for sending the human body induction trigger signal to the driving power switch circuit after signal conversion, so that the driving power switch circuit controls the LED light source to be switched from a non-full power mode to a full power mode for lightening. The LED explosion-proof induction lamp not only can meet intrinsic safety standard requirements, but also can achieve high-power explosion-proof illumination, automatic power adjustment and the like.

Description

technical field [0001] The application relates to the technical field of industrial lighting, in particular to an LED explosion-proof induction lamp, a control method and an intrinsically safe drive power supply device. Background technique [0002] For some high-power LED lighting fixtures in explosion-proof areas, especially explosion-proof lighting fixtures for industrial environments, when these high-power lighting fixtures work normally, due to the large number and high power, the energy consumption at this time is relatively high, and lasts for a long time. If it is turned on, the energy saving effect cannot be achieved, and the service life of the lamps will be shortened at the same time. However, these explosion-proof lamps must be in a lighting state in order to provide lighting for users or other equipment in real time. Therefore, it is very meaningful to design an LED explosion-proof lamp that can meet the explosion-proof requirements and has high-power lighting ...
