Special remote-controlled intelligent LED desk lamp for students

Abstract

The invention discloses a special remote-controlled intelligent LED desk lamp for students. A control circuit of the desk lamp comprises a single-chip microcomputer main control circuit, a dot matrix lighting circuit, an infrared remote-controlled sending and receiving circuit, an ultrasonic distance detection circuit, a voice circuit, and a key control circuit. The dot matrix lighting circuit, the infrared remote-controlled sending and receiving circuit, the ultrasonic distance detection circuit, the voice circuit and the key control circuit are connected with the single-chip microcomputer main control circuit. In addition to the basic functions of an ordinary LED desk lamp, the special remote-controlled intelligent LED desk lamp for students can intelligently identify the reading distance and prompt users in voice to prevent myopia, the desk lamp can be wirelessly and remotely controlled and is easy to operate, the brightness can be adjusted freely, the desk lamp has the function of a night lamp, and a lamp tube dot matrix enables static display of letters, numbers and patterns and dynamic display of graphics and patterns and makes the desk lamp highly personalized.

Description

technical field [0001] The invention belongs to the field of lighting devices of digital electronic technology, in particular to a remote-controllable LED intelligent desk lamp for students. Background technique [0002] Along with economic development, the raising of people's living standard, desk lamp is generally used in daily life illumination. Especially along with the popularization of LED lights, LED desk lamps are also widely used, but traditional LED desk lamps are mostly limited to lighting, which often cannot meet people's needs, especially to meet the individual pursuit of students. At present, the electronic circuits of desk lamps for students sold on the market are simple in structure and relatively single in function. Often, lighting and simple brightness adjustment can only be realized manually. Most of the circuit design schemes use relatively mature analog electronic technology. The degree of transformation is low. Contents of the invention [0003] The...
