Title:
LED DRIVING POWER SUPPLY, ILLUMINATION LIGHT SOURCE FOR REFRIGERATOR AND ILLUMINATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/208008
Kind Code:
A1
Abstract:
Disclosed in the present application are an LED driving power supply, an illumination light source for a refrigerator and an illumination device. The LED driving power supply comprises a linear driving circuit. By configuring a resistor in a VCC bus or a load loop of the linear driving circuit to divide the voltage, the IC power consumption is reduced and the IC temperature is reduced, thereby reducing the effect of heat dissipation of the IC on other elements. Furthermore, the service life of an LED lamp bead is prolonged.
