Description

Technical Field

[0001] The utility model relates to the technical field of refrigerator LED lights, in particular to a color-changing LED light for refrigerators. Background Art

[0002] A lighting lamp is installed in the refrigerator's refrigerator compartment, and the switch is adapted to the opening and closing of the refrigerator door. When the refrigerator compartment door is opened, the lighting lamp lights up synchronously, making it convenient for users to take out and put food or other refrigerated items at night or in a poorly lit environment. When the refrigerator compartment door is closed, the lighting lamp goes out.

[0003] In the prior art, patent publication number CN202818714U discloses a "refrigerator LED light circuit." This application stabilizes the voltage of the entire circuit by connecting resistors in parallel across a step-down capacitor at the input end and a voltage-divider resistor in series at the front end of the light-emitting circuit, preventing high voltages and protecting the LED lamp. However, this application has the following flaws: the refrigerator LED light's light-emitting circuit consists of six LED beads connected in series. If one LED bead fails, the entire LED lamp will not light up, resulting in poor stability. Furthermore, the refrigerator LED light in this application emits a single color, failing to achieve a color-changing lighting effect, resulting in a limited application scenario for the refrigerator LED light.
