It is electrically connected, the optocoupler is also electrically connected with LED light.
Preferably, control chip a control human pressure's sensor at seat end acquires human pressure's value, and by acquisition
Pressure value is sent to the wireless receiving module at desk end by wireless sending module, and pressure value is transferred to control by wireless receiving module
Coremaking piece b, control chip b combine the illumination intensity value of collected current environment to carry out judging whether to need to connect LED light, when
When illumination intensity value is all satisfied corresponding setting condition with pressure value, then LED light is connected.
The present invention due to using the technology described above, can obtain following technical effect:
1, the mutual cooperation of human pressure's sensing device and desk end intensity of illumination sensor is equipped with by seat end, it can be with
Illumination is opened when realizing someone on and seat darker in current environment；
2, being isolated for strong and weak electricity is carried out using optocoupler between chip b and LED light by controlling at desk end, to avoid danger
Danger；
3, it is attached by the control chip a at seat end and the control chip at desk end by 2.4G wireless module, from
And avoid wiring.
