Intelligent automated LED lamp for building corridors

Abstract

The invention discloses an intelligent automated LED lamp for building corridors. The intelligent automated LED lamp for building corridors comprises a corridor floor, households, a corridor exit andan elevator. An LED lamp body is mounted above the corridor floor, a pressure sensor and a timing device are arranged on the corridor floor at the outer end of a door of every household, a pressure sensor and a timing device are also arranged at each of an elevator door and the corridor exit, a control panel is further arranged on the wall of every storey and comprises a touch display screen, anda PLC (programmable logic controller) is arranged inside the control panel. The intelligent automated LED lamp for building corridors has the advantages that by the pressure sensors arranged at the exits of the storeys, people can be detected by the pressure sensors when entering and exiting every storey, and the LED lamp body is automatically turned on through the PLC, so that the problem that rest of the households is affected due to the fact that the sound control equipment is not sensitive and it is troublesome to turn on the lamp body is solved, external sound cannot affect on or off of the LED lamp body, energy is saved and usage is facilitated.

Description

technical field [0001] The invention relates to the technical field of building automation light control, in particular to an LED lighting lamp for intelligent automatic building corridors. Background technique [0002] LED is a solid-state semiconductor device that can convert electrical energy into visible light, which can directly convert electricity into light. The heart of the LED is a semiconductor chip, one end of the chip is attached to a bracket, one end is the negative electrode, and the other end is connected to the positive electrode of the power supply, so that the entire chip is encapsulated by epoxy resin. The semiconductor wafer consists of two parts, one part is a P-type semiconductor, in which holes dominate, and the other end is an N-type semiconductor, where electrons are mainly. But when the two semiconductors are connected, a P-N junction is formed between them. When the current acts on the wafer through the wire, the electrons will be pushed to the P...

Problems solved by technology

However, the lights in the existing corridors basically use voice control and light control. At night, when people walk into the corridor, many voice control devices are not sensitive, and people often stamp the ground hard or cough loudly. This is not only laborious, but also affects the rest of residents.

Furthermore, if the external sound is loud, the lights in the corridor will also be on, resulting in a waste of electric energy
