When two preset values, it may be determined that the intensity of illumination of current environment is smaller and the hand of user is close apart from remote controler 1, and user has operation
The wish of remote controler 1 then sends the second control instruction to the drive control module 5.
The drive control module 5 is used to control the remote controler backlight 6 according to the control instruction and open or close.
In the present embodiment, the drive control module 5 is used to control the remote controler according to first control instruction
Backlight 6 is closed；The drive control module 5 is used to control the remote controler backlight 6 according to second control instruction and open.It can
With understanding, microprocessor 4 be determine current environment intensity of illumination is larger or the intensity of illumination of current environment is smaller
But user is not close to the first control instruction exported in the case of remote controler 1 to drive control module 5, is determining current environment
Intensity of illumination is smaller and user has the second control exported in the case of the wish of remote controller 1 to drive control module 5
Therefore instruction when the received control instruction of drive control module 5 is the first control instruction, controls the remote controler backlight 6 and closes
It closes；When the received control instruction of drive control module 5 is the second control instruction, controls the remote controler backlight 6 and open.
Therefore, remote controler 1 provided by the present embodiment, on the one hand can be larger in intensity of illumination to avoid remote controler backlight 6
Environment in open, and then reduce remote controler backlight 6 generate energy consumption；It on the other hand can be in the lesser environment measuring of intensity of illumination
Whether user has the wish of remote controller 1, and then opens in user not in contact with control remote controler backlight 6 when arriving remote controler 1, just
Remote controler 1 is quickly found out in the environment of insufficient light in user.
