Light assembly

摘要

The present invention discloses a light assembly, which includes a transparent main body and a lens. The transparent main body includes an interior chamber gradually expanding from bottom to top, an inner wall encircling the interior chamber, and an outer wall encircling the inner wall. The outer wall is a total internal reflection surface. The inner wall includes a plurality of first facets facing a first direction and a plurality of second facets facing a second direction which is different from the first direction. The first facets and the second facets are provided to encircle the interior chamber respectively. Either side of each of the first facets is connected to one of the second facets, and each of the two adjacent first facet and second facet form an angle therebetween. The lens is fitted into the main body and faces the interior chamber of the main body.

1. A light assembly comprising:
a transparent main body including an interior chamber gradually expanding from bottom to top, an inner wall encircling the interior chamber, and an outer wall encircling the inner wall, wherein the outer wall is a total internal reflection surface and includes a plurality of circular plates; each two adjacent circular plates form an angle between 177° and 180° and the angle decreases from the top of the transparent main body to the bottom thereof; the inner wall includes a plurality of first facets facing a first direction and a plurality of second facets facing a second direction that is different from the first direction; the plurality of first facets and the plurality of second facets are provided to encircle the interior chamber respectively; either side of each of the first facets is connected to one of the second facets; each two adjacent first and second facets form an angle therebetween; the plurality of first facets are used to refract incident light toward the outer wall; the outer wall is used to reflect the light refracted by the plurality of first facets toward the plurality of second facets; and the plurality of the second facets are used to refract the light reflected by the outer wall toward a top end of the main body.
