Light distributing component, light source module, lawn lamp cap and lawn lamp

Alight source module comprising a substrate, light-emitting units and a light distributing component, wherein the light distributing component comprises an inner ring polarizing lens and an outer ring polarizing lens, wherein:

• the inner ring polarizing lens and the outer ring polarizing lens have a common axis center, and the outer ring polarizing lens surrounds the inner ring polarizing lens;
• the inner ring polarizing lens is configured to deflect light of a light-emitting unit toward a direction close to the axis center, a midline of an illumination range of the inner ring polarizing lens and the axis center form a first included angle, and the first included angle is an acute angle;
• the outer ring polarizing lens is configured to deflect light of the light-emitting unit in a direction away from the axis center, a midline located in an illumination range of the outer ring polarizing lens and the axis center form a second included angle, and the second included angle is an acute angle;
• the inner ring polarizing lens and the outer ring polarizing lens comprise a groove in a ring shape, and a cross section of the groove along the axis center is of a trapezoid shape;
• the substrate has a first surface and a second surface that face away from each other, and the light-emitting units are arranged in a ring shape on the first surface;
• and
• the light distributing component covers the first surface;
• and the inner ring polarizing lens and/or the outer ring polarizing lens distribute light of the light-emitting units.

A lawn lamp cap comprising a top cover, a base and a light source module;

• wherein the light source module comprises a substrate, light-emitting units and a light distributing component, wherein the light distributing component comprises an inner ring polarizing lens and an outer ring polarizing lens, wherein:

• the inner ring polarizing lens is configured to deflect light of a light-emitting unit toward a direction close to the axis center, a midline of an illumination range of the inner ring polarizing lens and the axis center form a first included angle, and the first included angle is an acute angle;
• the outer ring polarizing lens is configured to deflect light of the light-emitting unit in a direction away from the axis center, a midline located in an illumination range of the outer ring polarizing lens and the axis center form a second included angle, and the second included angle is an acute angle;
• the inner ring polarizing lens and the outer ring polarizing lens comprise a groove in a ring shape, and a cross section of the groove along the axis center is of a trapezoid shape;
• the substrate has a first surface and a second surface that face away from each other, and the light-emitting units are arranged in a ring shape on the first surface;
• the light distributing component covers the first surface;
• and the inner ring polarizing lens and/or the outer ring polarizing lens distribute light of the light-emitting units;
• and
• the top cover and the base are arranged opposite to each other;
• a region enclosed by the top cover and the base is a light source cavity;
• the light source module is arranged at an end of the light source cavity that is close to the top cover;
• and a first surface faces the base.
