Embodiment 1
[0047] Please refer to figure 1 with figure 2 , the present embodiment proposes an LED explosion-proof induction lamp 100, which can be applied to the above-mentioned industrial places such as coal mines.
[0048] Exemplarily, as figure 1 As shown, the LED explosion-proof sensor lamp 100 includes: an LED control board 20 and an LED light source 5 located inside the explosion-proof housing 10 , and a pyroelectric infrared sensor probe 3 located outside the explosion-proof housing 10 . For example, the LED light source 5 is disposed on an end face of the explosion-proof housing 10 , and at this time, the end face can be defined as the top of the explosion-proof housing 10 , while the end face far away from the LED light source 5 is defined as the bottom. In this embodiment, the explosion-proof housing 10 includes a housing body and an explosion-proof lampshade 110 , wherein the explosion-proof lampshade 110 is arranged in the light emitting direction of the LED light source 5...
Embodiment 2
[0064] Please refer to Figure 7 , this embodiment proposes a control method for an LED explosion-proof sensor lamp, which can be applied to the LED explosion-proof sensor lamp in the above-mentioned embodiment 1. Exemplarily, the control method for the LED explosion-proof sensor lamp includes:
[0065] Step S110, detecting in real time whether the pyroelectric infrared sensing probe generates a human body trigger signal.
[0066] After being powered on, the driving power switch circuit 1 in the LED explosion-proof sensor lamp can continuously sample the corresponding signal terminal connected to the pyroelectric infrared sensor probe to detect whether the probe generates a human body trigger signal.
[0067] Step S120, if a human body trigger signal is detected, control the LED light source to switch from the current non-full power mode to the full power mode to light up.
[0068] If the human body trigger signal is detected, the control will switch from the current non-full...
