[0024] The above-mentioned induction lighting system for petrochemical device operation and inspection is set up and demarcated within the petrochemical device operation and inspection area 1 as an induction area. In this embodiment, the demarcated area is the channel entrance 11. An infrared human body sensor 300 is set at the channel entrance 11. The infrared human body sensor 300 is an automatic control product based on infrared technology. When someone enters the channel entrance 11, the infrared human body sensor 300 detects the change of the infrared spectrum of the human body, and turns on the lighting control circuit 200, that is, turns on the load LED lamp 100. If the person does not leave the channel entrance 11, it will continue to be turned on. After the person leaves, the load LED lamp 100 will be automatically turned off. In this way, the light turns on when the person arrives and turns off when the person leaves, thereby achieving the purpose of energy saving and safe operation.

[0025] In one embodiment, the petrochemical device operation and inspection area 1 is defined with the operation and inspection equipment as the center, and the LED lamp 100 is arranged next to the operation and inspection equipment.

[0026] Preferably, in one embodiment, the lighting controller 210 with a built-in delay adjustment function (adjustable from 0 to 60 seconds) can be used to achieve delayed automatic shutdown of the load LED lamp 100, which is more reasonable and convenient.

[0028] See also Figure 4 In one embodiment, a plurality of LED lamps 100 are provided, which are respectively arranged on different floors of the steel ladder in the petrochemical device operation and inspection area 1. As an example, one LED lamp 100 is provided on each floor. When specifically provided, an infrared human body sensor 300 can be provided at the position of the passage entrance 11 corresponding to each floor. After the infrared human body sensor 300 senses the change of the infrared spectrum of the human body, the lighting control circuit 200 of the corresponding floor is turned on, and then the load LED lamp 100 corresponding to the floor is turned on.

[0029] In the specific setting, in one embodiment, the nth floor has an nth floor channel entrance 11a and an nth floor channel exit 13a, the nth floor channel entrance 11a is lower than the nth floor channel exit 13a, the nth floor channel entrance 11a is suspended above the nth floor channel entrance 11a, and the nth floor channel exit 13a is provided with an nth floor LED lamp 100a.

Such a configuration can better protect the circuit and the LED lamp 100, thereby making the operation of the induction lighting system for petrochemical device operation and inspection more reliable.

[0034] In one embodiment, the model of the infrared human body sensor 300 is BZK-16.

[0035] The utility model divides the petrochemical device operation and inspection area 1, and sets a channel entrance 11 at the same time.
