1. A light reflecting structure, configured to reflect light emitted from a plurality of light-emitting units, wherein the light reflection structure comprises:
a bottom portion;
a plurality of sidewall portions standing on the bottom portion, wherein the sidewall portions respectively and correspondingly surround the light-emitting units, and the light emitted from each light-emitting unit can be directed to a reflecting surface corresponding to each of the sidewall portions to be reflected outward;
wherein there is a distance P between any two adjacent sidewall portions, and each of the sidewall portions has a height H1, and wherein the distance P and the height H1 satisfy a first inequality, and the first inequality is:
wherein θ represents a complementary angle of a half light-intensity angle of each of the light-emitting units;
wherein the sidewall portions are connected to each other through a plurality of junction portions, and each of the junction portions is a non-steeple structure; and
wherein each of the light-emitting units emits a first portion of light, the first portion of light includes a light emitted at the half light-intensity angle, and the first portions of light emitted from any two adjacent light-emitting units pass through a location above the junction portion.
