Solar light-emitting diode (LED) voice-controlled corridor lighting system

Abstract

The invention discloses a solar light-emitting diode (LED) voice-controlled corridor lighting system which comprises an LED lamp, a voice-controlled unit, a delay control unit, a singlechip and a power supply unit, wherein the LED lamp is used for lighting in a corridor; the voice-controlled unit is used for turning on the LED lamp and comprises a voice acquisition device and a tone discrimination device; the delay control unit is used for delaying after the LED lamp is turned on by the voice-controlled unit; the singlechip is electrically connected with the voice-controlled unit and the delay control unit respectively; the power supply unit is used for supplying power to the LED lamp, the voice-controlled unit, the delay control unit and the singlechip and comprises a solar cell panel, a charging circuit, a storage battery and a conversion circuit which are sequentially connected; the tone discrimination device is provided with a tone feature library of pre-extracted voices of corridor users; the voice acquisition device is used for sending the acquired voice to the singlechip for tone feature extraction; and the singlechip is used for comparing the extracted tone feature with the tone feature of the tone feature library and sending discrimination information to the LED lamp through the delay control unit. The solar LED voice-controlled corridor lighting system has the advantages of safety for the corridor users, energy saving and environmental friendliness.

Description

technical field [0001] The invention relates to the field of intelligent lighting, and more specifically, the invention relates to a solar LED sound-controlled corridor lighting system. Background technique [0002] The corridor lighting system initially used incandescent lamps. Incandescent lamps are prone to heat and cause a lot of energy loss. Incandescent lamps are gradually replaced by energy-saving lamps. Energy-saving lamps have relatively high luminous efficiency and good energy-saving effect. At present, the corridor lighting system also uses LED lights, which have pure colors, good energy saving effects and long service life. As for the induction control technology part of the corridor lighting system, it mainly uses sound induction or infrared induction, that is, to light the corridor through sound or temperature infrared induction, which can not only meet the corridor lighting at night, but also save energy to the greatest extent. However, with these two sensin...

Problems solved by technology

However, with these two sensing methods, any visitor can light up the corridor by entering the corridor or making a sound, which increases the unsafety of the corridor at night.
