Description

Technical Field

[0001] The utility model belongs to the technical field of children's daily necessities, and in particular relates to a dual-mode children's projection lamp. Background Art

[0002] The principle of children's projector lamps is mainly based on the rectilinear propagation of light and the imaging principle of convex lenses. The light emitted by the light source is refracted and focused by the lens to form a beam, which is then projected onto planes such as walls and ceilings. When the light encounters an opaque object during propagation, a dark area, i.e. a shadow, is formed behind the object. When the surface of an object has texture or is uneven, the light will be scattered or reflected to form different shadow effects. These shadow effects can form colorful patterns and animations on the projection surface, attracting children's attention and creating an environment full of fun and imagination.

[0003] However, existing projection lamps on the market basically project in a fixed direction; the existing Chinese utility model patent with announcement number CN208546907U provides a projection lamp, which includes a base assembly, on which a light source, a light shield and a control device that can control the opening and closing of the light source are arranged, the light shield is located above the light source and can block the light emitted by the light source, the light shield has a plurality of light-transmitting parts, the light emitted by the light source passes through the light-transmitting parts, and then is projected onto the ceiling or the wall, thereby creating a night starry sky environment, which is conducive to children's sleep and has good decorative and lighting effects; however, its projection direction is relatively fixed and inconvenient to adjust.
