technical field

The utility model relates to the field of projection lamps, in particular to a projection lamp for scrolling projection patterns.

Background technique

Lighting is an important means to decorate and beautify the environment and create an artistic atmosphere. In order to decorate the interior space, increase the level of space, and render the atmosphere of the environment, more and more decorative lighting is used, which makes decorative lamps very important. In the interior and exterior design of modern home architecture, film and television architecture, commercial architecture and entertainment architecture, lighting has become a part of the overall design. Lamps not only play a role in ensuring lighting, but also pay attention to their shapes, materials, colors, proportions, and scales. Lamps have become indispensable decorations for indoor spaces. Lighting designers give full play to the brilliance and color of lights through rhythmic control of light and shade, looming, circumflex, and strength, and use various means such as transmission, reflection, and refraction to create a warm, soft, quiet, elegant, and pleasant environment. Romance, splendor, magnificence, joy and festivities, fast-paced, mysterious, confusing and other artistic atmospheres add rich and colorful flavors to people's living environment.

In addition, in order to enrich the means of lighting design, pattern projection lights have appeared in the prior art, which project pre-designed patterns onto the surface of the target object through light. In addition to playing a certain decorative effect, it is often used in some occasions It is used as a means of propaganda, and the propaganda target is projected as a pattern on the surface of the target object through the pattern projection lamp. In addition to having a decorative effect, it also achieves the purpose of advertising. However, in the prior art, the pattern projected by the projection lamp can only be projected to a fixed point, and the movement of the pattern cannot be realized, and the brightening or darkening of the pattern is rather abrupt, and there is no process of fading in or out.
