LED table lamp having eye protection function and suitable for primary and secondary school students

Abstract

The invention discloses an LED table lamp having an eye protection function and suitable for primary and secondary school students. The LED table lamp comprises a shell; four supporting seats are fixed to the outer wall of the bottom of the shell through bolts and located at the four corners of the outer wall of the bottom of the shell correspondingly; a supporting rod is fixed to the outer wall of the top of the shell through a bolt; a rotary sleeve is fixed to the outer wall of the top of the supporting rod through a bolt; a rotary shaft is rotationally connected to the interior of the rotary sleeve; a connection rod is fixed to the outer wall of one side of the rotary shaft through a bolt and internally provided with a cavity; and a processor is fixed to the inner wall of the top of thecavity through a bolt. According to the LED table lamp, the distance between a user and the table lamp can be well measured, when the head is located within the induction range of a distance sensor,an alarm device gives out an alarm under control of the processor, and the situation that the user is injured due to the fact that the distance between the user and the table lamp is too small is prevented; and the LED table lamp has the function of protecting eyes of the user, and heat energy generated during working of the table lamp can be discharged quite well.

Description

technical field [0001] The invention relates to the technical field of LED desk lamps, in particular to an LED desk lamp with an eye protection function suitable for primary and middle school students. Background technique [0002] At present, a desk lamp is a household appliance used for lighting in people's lives. It is generally divided into two types, one is a column type, and the other is a clamp type. Its function is to concentrate the light in a small area for easy work and study. The light bulbs used in general table lamps are incandescent lamps, energy-saving light bulbs, and popular eye-protection table lamps on the market. Some table lamps also have an "emergency function", that is, their own power supply, which is used for emergency lighting in the event of a power outage. [0003] When the LED desk lamp in the prior art is used, the device has poor eye protection function, poor adjustability, poor heat dissipation and low service life. Therefore, there is an u...
