Qianzhao Optoelectronics applies for LED chip patent, which can reduce the size of LED chips

div class content id article News from the financial industry on June 18, 2024. Intellectual property information from Tianyancha shows that Meixinsheng Technology (Beijing) Co., Ltd. has obtained a project called LED constant current control circuits, control equipment, LED equipment and integrated circuits. The authorization announcement number is CN221151606U. The application date is October 2023. div class dpu8C 2kCxD p The patent summary shows that this application provides an LED constant current control circuit, control equipment, LED equipment and integrated circuit, including: a discharge control module, a constant current control module, a first capacitor and a one-way conduction module; the input current of the external power supply is input to the first capacitor through the one-way conduction module to charge the first capacitor. The input current or the first capacitor current discharged by the first capacitor is input to the load through the constant current control module to realize flicker-free constant current power supply to the load. The discharge control module is used to allow the first capacitor to discharge and power the load when the input voltage is lower than the set value. When the input voltage is higher than the set value, the first capacitor is prevented from discharging. In this process, a lower set value is set to make the input current have a phase angle within a half-wave of the input voltage. The width is increased, improving the PF value. p div div class dpu8C 2kCxD p br p div div
