Intelligent LED lamp

Abstract

The invention discloses an intelligent LED lamp. The intelligent LED lamp comprises a main control unit, a dot-matrix LED lamp bead unit, a human body activity detection unit, a light ray induction unit and a wireless communication unit, wherein the dot-matrix LED lamp bead unit comprises LED lamp beads arranged on an aluminium substrate in the form of a dot matrix, and a drive unit, and the drive unit is capable of driving each LED lamp bead to be turned on and off; the light ray induction unit comprises a photosensitive device used for detecting an ambient light ray; the human body activity detection unit comprises a controller and more than two ultrasonic sensors, the ultrasonic sensors are connected to the controller, and used for sending ultrasonic signals and receiving the returned ultrasonic signals, and the controller is used for processing the ultrasonic signals, and calculating whether the position of an object in a monitoring range is changed or not; and the main control unit is used for controlling the dot-matrix LED lamp bead unit to work in a full illumination mode, a local illumination mode or a night lamp mode. The intelligent LED lamp has the functions and the applications of many lamps, and is high in intelligence and convenient to use.

Description

technical field [0001] The invention relates to the lighting field, in particular to an intelligent LED lamp. Background technique [0002] LED (Light Emitting Diode), light-emitting diode, is a solid-state semiconductor device that can convert electrical energy into visible light, and it can directly convert electricity into light. The heart of LED is the wafer of a semiconductor, and one end of wafer is attached on a bracket, and one end is negative pole, and the other end connects the positive pole of power supply, and whole wafer is encapsulated by epoxy resin. LED has the advantages of energy saving, environmental protection, and long life, and has been widely used in household lighting, industrial lighting and other lighting fields. [0003] In home lighting, lighting fixtures are divided into main lighting (such as chandeliers, ceiling lamps), local lighting (such as wall lamps, reading lights) and dark lighting (such as night lights) according to different functio...

AI Technical Summary

Problems solved by technology

In order to meet different functions, in the bedroom or hall, it is usually necessary to install more than two lamps with the above-mentioned different functions, as well as control switches corresponding to different lamps. Not only the cost of the lamps is high, but also the installation and wiring of the lamps are difficult.

In the existing home lighting field, there have been applications of intelligent technologies such as voice control, light control, or human body infrared induction control. inconvenient and not smart

For example, when the family members are sleeping at night, the sound control of the voice-activated lights in the living room may wake up other sleeping people, and the infrared sensing technology is not suitable for the night light control in the bedroom (ideally, the night light is used when people are sleeping, It should be off, and it will be turned on when people get up, and the infrared sensing technology cannot sense whether people in the room are sleeping or active, so it cannot intelligently control the night light on and off, and is not suitable for night light control in the bedroom)
