Abstract

The invention discloses an infrared induction brightness control circuit, and the circuit at least comprises an infrared detection module which comprises one or more infrared induction devices and a start switch, wherein one end of each infrared induction device is connected with a power voltage, the other end of each infrared induction device is connected with the start switch, and the start switch is used for the connection of a detection signal or the power voltage. The circuit also comprises an integral circuit, and the integral circuit is connected with the start switch, so as to eliminate sharp pulse interference in the infrared signal detected by the infrared detection module. The circuit also comprises a drive circuit, and the drive circuit is connected with the output end of the integral circuit, so as to enable the infrared signal with the sharp pulse interference being eliminated to be driven and then transmitted to a line-field scanning brightness input end of display equipment. The circuit enables the infrared induction devices to be connected to the line-field scanning brightness input end of display equipment through the integral circuit and the drive circuit, thereby enabling the brightness of the display equipment to be lower when the intensity of the infrared signal is higher, and preventing the brightness signal if the display equipment at a short distance from stimulating the eyes of a child.

Description

technical field [0001] The invention relates to a control circuit, in particular to an infrared induction brightness control circuit. Background technique [0002] At present, household appliances, especially televisions and computers, are very popular, and children and even infants spend significantly more time using these display devices. Some two channels like to watch or play close to the display device. The bright display device is easy to cause vision damage, especially for infants whose eyes are not yet fully developed. Because their eyes are not yet fully developed and their eyesight is poor, they prefer to watch or Playing very easily damages its fragile eyes, therefore, it is necessary to propose a technical means to solve the above problems. Contents of the invention [0003] In order to overcome the deficiencies in the above-mentioned prior art, the object of the present invention is to provide an infrared sensing brightness control circuit by connecting the i...
