Ensure that human eye can normally identify the position of switch, and a kind of this condition often only has meet daytime, once to evening, people
To want turn on lights in dark conditions just extremely difficult, can only many times be groped ahead through the darkness with sensation until open
Light is opened, and this process is extremely hazardous.
(2) most of intelligent switch on the market be Unicolor back light and backlight color be it is specific, it is non-adjustable.Present market
On intelligent switch, depending on backlight color is all the color customized according to user before dispatching from the factory, user can not change.Product is used
After time length, user can produce aestheticly tired to this class color, and these intelligent switch are all long-time light yellows, and
It can not be controlled by ambient lighting value and human inductor, cannot also reduce work(unnecessary under unmanned environment on daytime
Consumption.
Disclosed on 03 23rd, 2016, disclosed in Publication No. CN 104080252B Chinese invention patent application
It is a kind of with human body close to the intelligent switch of perceptional function, on the basis of the existing intelligent switch, add human body close to sense
Module and backlight adjustment module are answered, wherein, human body is used to obtain human body and intelligence of the user in induction range close to induction module
The distance between energy switch information and switch surrounding environment optical information, are then fed into the system level chip in integrated circuit modules
Calculated and analyzed, according to ambient light, judge the environment period of intelligent switch, if the sensing opening time in setting
Section, then start human body close to inducing function, and obtains the strong higher backlight illumination regulating command of distance more dipped beam；Backlight adjusts mould
Block is used to being converted to backlight illumination regulating command into actual light efficiency.The invention is only merely to realize the work(that backlight is automatically adjusted
Can, and the effect of backlight is to facilitate night to turn on light, such as fruit product installation region ratio is larger than investigative range, and that user is remote
It is that can not judge the position of switch, and backlight does not support color adaptation, thus limit user installs and uses scope and experience
