Abstract (en)
The patent relates to the field of projection lamps and discloses a projection lamp for simulating a sky effect, comprising a first light-emitting component, wherein the first light-emitting component comprises a first light source for generating a first light ray, a first frosted glass arranged on an optical path of the first light ray and a convex lens, which are sequentially arranged. The first light ray emitted by the first light source is projected onto one surface through the first frosted glass and the convex lens to exhibit a cloud effect. The patent provides a first frosted glass between a first light source and a convex lens. The first light ray emitted by the first light source exhibits a cloud effect shaped like cotton on one surface after passing through the first frosted glass and the convex lens so as to achieve the purpose of creating a sky effect indoors.
