Title:
STAGE LAMP CONTROL SYSTEM HAVING PHOTOBIOLOGICAL SAFETY AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/012843
Kind Code:
A1
Abstract:
The present invention relates to a stage lamp control system having photobiological safety and a control method therefor. The control system comprises a control unit and a distance sensor connected to the control unit; a stage lamp comprises a lamp holder provided with a light source therein and a motor for driving the lamp holder to change an irradiation position. The control unit is connected to the motor and the light source, and is used to control the operation of the stage lamp; the distance sensor is provided on the lamp holder and is used to acquire an instant distance d from a living being to a stage lamp; a light radiation harm exposure limit E harm and a pre-acquired lamp irradiance value E S per unit time and unit distance are stored in the control unit; the control unit acquires, according to the instant distance d, the light radiation harm exposure limit E harm and the lamp irradiance value E S, a parameter of the living being entering an irradiation danger zone; and when a dangerous condition reaches the parameter of the living being entering the irradiation danger zone, the control unit controls actions of the stage lamp to eliminate the harm. The present invention replaces the defense of label warning with self-regulating defense, avoiding the impact of artificial light sources on human health.
