A starry sky aurora atmosphere lamp with an integrated lampshade is provided, including a base, a main light source, a multi-layer housing, and a connector. The main light source is arranged at a center of the base and can project light upwards to form a starry sky atmosphere light. The multi-layer housing can cover the base, such that the main light source is located within an accommodating space formed between the base and the multi-layer housing. The multi-layer housing includes an inner light-gathering cover and a semi-obscuring outer cover covering a surface of the light-condensing inner cove. The connector connects the base with the multi-layer housing. When the multi-layer housing is rotated to cover the base, the multi-layer housing and the base have integral and continuous appearance, and the starry sky atmosphere light is automatically changed to colored glaze light of a small night lamp.

A projection device with dynamic light effect is provided, which includes at least one LED light source, a condensing lens, at least one external projection mono-convex lens, and further includes at least one filter. The filter is located between the condensing lens and the external projection mono-convex lens, an out-light surface of the condensing lens is provided with a first ripple. An upper and/or a lower surface of the filter are provided with a second ripple; being refracted by an interference pattern on the first ripple through the condensing lens, emitted light corresponding to the interference pattern on the first ripple is formed. Then, the light passes through the filter and undergoes two refractions. The light is refracted by the interference pattern on the second ripple, resulting in a refraction effect of the interference pattern superimposed on the first ripple and second ripple.

of the Invention Disclosed herein an apparatus for mimicking the light and sky-conditions at the horizon comprises a light assembly (2) provided with at least two angularly disposed horizontal strips (9a and 9b) of light source, a composite lens (5) fixedly placed above the light assembly (2) and configured to selectively reflect and transmit the light incident on it, a reflecting dome (3) centrally and partially disposed over the composite lens (5) and light assembly module (2) and provided with an LED spotlight (12) under it, a mounting bracket (4) adapted to receive the light assembly and the composite lens; and a controller (11) configured to control and monitor one or more predetermined parameters of the light source (9), wherein the characteristic of the composite lens (5) is translated depending on the desired geographical location. A corresponding method for mimicking the light and sky-conditions at the horizon is also disclosed.

A lighting apparatus, in particular in the form of ceiling spots, with a perforated panel having at least one aperture for light to pass through, as well as a lens arranged so as to be concealed behind the perforated panel to emit a bundle of light beams that narrows on its way from the lens to the perforated panel, passes through the aperture for light to pass through, and broadens again after leaving the perforated panel. The lens is shaped in such a manner that a direct beam portion and/or direct light portion emitted without reflection from the lens and an indirect beam portion and/or indirect light portion emitted with reflection from the lens have essentially identical beam angles, and each essentially completely make up and/or fill out the overall bundle of light beams emitted by the lens.

A children's toy, and electronic device, plays audio files and projects differently-colored light patterns onto a surface in a room in which the device is placed. The light patterns are projected in synchronization with the playback of such audio files. The device allows users to select from different nature sounds, different melodies, or multiple pre-recorded children's stories. The device also enables users to record their own stories for each of several environments, and playback their custom stories together with projections of light in each environment.
