Relatively strong, LED illumination lamp is darker, conversely, LED illumination lamp is then brighter, so as to realize automatically adjusting the purpose of intensity of light, both avoids
Energy waste, also helps protection vision.
Further, the desk lamp control system also includes infrared sensor, signal processor and voice prompting device；It is described
Infrared sensor：For detecting the distance between human body and described LED illumination lamp, and detection signal is converted to into the signal of telecommunication, so
Send the signal of telecommunication to signal processor afterwards；The signal processor：It is for receiving the signal of telecommunication of infrared sensor transmission and right
The signal of telecommunication is amplified and compares, and then detects effective trigger, then sends trigger to microcontroller；It is described micro-
Controller：It is additionally operable to receive the trigger of signal processor transmission and process, then sends the signal after process to voice
Prompting apparatuss；The voice prompting device：For receiving the signal of microcontroller transmission and sending suggestion voice or closing according to signal
Suggestion voice.In order to avoid human body proximity even zero distance contact LED illumination lamp, the present invention is provided with voice prompting device, and one
Denier infrared sensor detects human body and is issued by voice message with the distance of LED illumination lamp less than preset value, prevents human body excessive
Cause visual fatigue near light source.
Further, the infrared sensor is pyroelectric infrared sensor.The rpyroelectric infrared that the present invention is adopted is passed
Sensor itself will not send any kind of radiation, and device power consumption is little, good concealment, and cheap, not only environmental protection but also can drop
Low cost.
The beneficial effects of the present invention is：One aspect of the present invention can automatically adjust LED illumination lamp according to light intensity
Intensity of illumination, is conducive to protecting vision, and user on the other hand can be reminded by voice prompting device to keep a spacing with lamp source
From can be prevented effectively from human body causes visual fatigue because excessive near light source；And the rpyroelectric infrared used by the present invention is passed
Sensor was not only radiationless but also cheap, not only cost that is environmentally friendly but also can reducing the present invention.
