Double-power-feeding intelligent table lamp based on single-chip-microcomputer image recognition and automatic luminance adjustment

Abstract

The invention discloses a double-power-feeding intelligent table lamp based on single-chip-microcomputer image recognition and automatic luminance adjustment. The double-power-feeding intelligent table lamp comprises an intelligent table lamp, a master control device, a driving device and an external driving device, wherein the intelligent table lamp comprises an LED (Light Emitting Diode) lamp, a camera, a steering engine and a photosensitive sensor; the camera, the steering engine and the photosensitive sensor are all connected with the master control device; the driving device is used for supplying working voltage to the LED lamp; the driving device comprises a rectification and filtering module, an IPM inversion module and a DC adapter which are connected with each other in turn; the IPM inversion module is used for receiving a frequency signal outputted by the master control device and inverting direct current fed by the rectification and filtering module into an alternating current and then outputting. According to the double-power-feeding intelligent table lamp, through the interaction of the master control device and the intelligent table lamp, the ambient light strength can be read; the condition of human activity in front of the table lamp can be recognized; the luminance adjustment of the table lamp becomes intelligent; the electric energy loss can be reduced and the eyestrain can be relieved to a certain extent; the phenomenon that a user forgets to turn off the lamp can be avoided; the intelligence and automation can be realized.

Description

technical field [0001] The invention relates to an adjustable light source, in particular to an intelligent desk lamp with dual power supply for image recognition and brightness automatic adjustment based on a single chip microcomputer. Background technique [0002] For students and working people who widely use desk lamps, the existing desk lamp devices have the following problems: [0003] 1. The brightness of the lighting is artificially changed through buttons or switches, and the brightness level is fixed, which cannot meet the requirements of brightness lighting under certain specific conditions; [0004] 2. Due to the busy study and life, etc., you may forget to turn off the lights and cause a waste of electric energy. At present, most of the desk lamps with automatic switch lights use infrared sensing technology. When the human body activity is slight in front of the desk lamp, the infrared recognition ability is poor; [0005] 3. At present, some desk lamps do not...

AI Technical Summary

Problems solved by technology

[0003] 1. The brightness of the lighting is artificially changed through buttons or switches, and the brightness level is fixed, which cannot meet the requirements of brightness lighting under certain specific conditions;

[0004] 2. Due to the busy study and life, etc., you may forget to turn off the lights and cause waste of electric energy

At present, most of the desk lamps with automatic switch lights use infrared sensing technology. When the human body activity is slight in front of the desk lamp, the infrared recognition ability is poor;

[0005] 3. At present, some desk lamps do not have the function of clock and desk lamp timing switch, and the human-computer interaction effect is less;

[0006] 4. Most of the existing desk lamp power supply is directly connected to 220V AC. The small portable desk lamp is connected to the DC adapter through the USB port. The functions are scattered, and different models often need to be purchased separately.
