As a kind of further improvement of multifunctional intelligent LED desk lamp of the utility model：The warm white of the LED component The colour temperature of LED array is 3000K, and the colour temperature of cool white LED array is 6000K.

Beneficial effect

1st, multifunctional intelligent desk lamp of the present utility model, dimmed using warm white LED array and cool white LED array with LED Driving power connects, and is adjusted by single-chip microcomputer by PWM control modes, realizes light output of the LED component from 1% to 100%, Take good care of the vision health of user；

2nd, multifunctional intelligent desk lamp of the present utility model, single-chip microcomputer can be allowed to current LED component by remembering button Brightness and colour temperature carry out memory storage, and provide three storage shelves, brightness and colour temperature regulation after the completion of, press corresponding gear Remember button, present intensity and colour temperature can be remembered, next time presses respective notch button when starting, being capable of key regulation To the brightness set by last time and colour temperature, meet the lighting demand of different members in family；

3rd, multifunctional intelligent desk lamp of the present utility model is provided with eyeshield pattern and normal mode, and eyeshield pattern is opened When, the reading distance of reader can be measured in real time by the infrared ray sensor of setting, if hypotelorism, light is just automatic It is dimmed or even extinguish, and leave predetermined distance, light then brightens automatically, be particularly suitable for reminding primary and secondary students read a book under lamp or When doing one's assignment, it is impossible to it is excessively near apart from lamp, and be provided with piezoelectric loudspeaker and carry out voice message.
