Description

Technical Field

[0001] This utility model relates to the field of projection lamps, and more particularly to a solar projection lamp. Background Technology

[0002] The working principle of a projector lamp is mainly based on photoelectric conversion, which is based on the light emitted by the lamp beads. The light is then shone onto the projection sheet through a condenser lens, and finally a pattern or text is projected. Projector lamps usually use elliptical reflector spotlights, which generate a clearly defined circular beam of light through a reflector. Pattern sheets are inserted in the light path to control the shape of the light and the shadow. The pattern sheets can be simple text, complex patterns, or dynamic animations, thereby achieving a variety of visual effects.

[0003] Projector lights have a wide range of applications, such as creating lighting scenes on theatrical stages or creating dynamic visual effects in nightclubs and music venues. In addition, projector lights can also be used in hotel home theaters to provide clear picture quality and a good live effect. As a decorative element, they are currently widely used in home decoration, store reception, and other scenarios.

[0004] Currently, most projector lights used in home or commercial settings are relatively high-power products, with a basic power of 20W or more. They require separate wiring for installation, which greatly increases the cost of materials and labor. Many projector lights used outdoors operate on 220V AC voltage, and waterproofing and insulation must be carefully considered during wiring installation, further increasing costs and posing certain safety hazards.

[0005] Therefore, it is necessary to provide a solar-powered projection lamp to solve the above-mentioned technical problems. Utility Model Content

[0035] Compared with related technologies, the solar projection lamp provided by this utility model has the following beneficial effects:

[0036] This utility model provides a solar projection lamp with a satellite-style double-panel foldable, multi-angle adjustable solar charging photovoltaic panel 3. The optimal light-gathering angle can be adjusted, and the double-panel solar charging power is better. Utilizing the solar light-sensing characteristics, it automatically senses light, charges during the day, and automatically lights up the projection spotlight at night. This device has a simple structure and is highly practical. It uses an integrated solar panel for power generation, and the product has a built-in battery for low-voltage power supply.
