Low-Voltage Light Strip

A low-voltage light strip, comprising a light strip body, at least one set of light-emitting units packaged on the light strip body, and a flexible protective sleeve arranged on an outer side of the light strip body and the light-emitting units;

• wherein
• each of the light-emitting units comprises a constant current circuit and an LED light string, an input end of the constant current circuit being connected to a power source, and an output end of the constant current circuit being connected to the LED light string;
• the LED light string comprises at least one LED light bead, which comprises an LED chip, an encapsulant encapsulating the LED chip, and a first optical layer arranged between the encapsulant and the LED chip;
• the first optical layer covers a surface of the LED chip, a refractive index thereof being between a refractive index of the LED chip and a refractive index of the encapsulant;
• and
• a surface of the flexible protective sleeve is provided with a second optical layer, a refractive index of the second optical layer being between a refractive index of the flexible protective sleeve and a refractive index of air.
