Problems solved by technology
[0002] Existing corridor lights (such as lighting in stairwells) generally use incandescent lamps, which have poor energy-saving effects. In addition, since this kind of lamp has only a single circuit, once the circuit fails, the corridor will be in the dark when the light is poor. Or the dark state, which brings a lot of inconvenience to the residents, what's more, it is easy to cause the elderly to fall
[0003] There is no alarm device after a fault occurs, and it is difficult to report for repairs, and it can only be used normally after repairs by maintenance personnel

The invention discloses an intelligent light-emitting diode (LED) corridor lamp which comprises a micro processor, a first direct current power supply, a second direct current power supply, N LED branch circuits, N groups of relays, N amplifiers, N analog (A) / digital (D) converters and an alarm; the alarm is connected with one output port of the micro processor; each LED branch circuit is formed by connecting a current-limiting resistance, a normally open switch of the relay and an LED light string in series, wherein LED light string negative poles which are used as one end points of the LED branch circuits are all connected with a ground wire of the first direct current power supply, and the other end points of the LED branch circuits are connected with a positive voltage end (V plus) of the first direct current power supply; the positive poles of the N LED light strings are respectively and sequentially connected with the N input ports of the micro processor through the N amplifiers and the N A / D converters; and the N output ports of the micro processor are respectively connected with the coils of the N groups of relays through N same switch drive circuits. The intelligent LED corridor lamp has the functions of automatic branch circuit switching and automatic alarming, is convenient and practicable, is easy to carry out, and has good energy-saving performance.
Description
technical field [0001] The invention relates to an intelligent LED gallery lamp. Background technique [0002] Existing corridor lights (such as lighting in stairwells) generally use incandescent lamps, which have poor energy-saving effects. In addition, since this kind of lamp has only a single circuit, once the circuit fails, the corridor will be in the dark when the light is poor. Or the dark state brings a lot of inconvenience to the residents, what's more, it is easy to cause the elderly to fall and hurt. [0003] After the fault occurs, there is no alarm device, so it is difficult to report for repair, and it can only be used normally after the maintenance personnel repair it. [0004] In view of this, it is necessary to design a brand-new intelligent LED corridor light. Contents of the invention [0005] The technical problem to be solved by the present invention is to provide an intelligent LED corridor light, which has automatic branch switching and automatic al...
