Description

TECHNICAL FIELD

The present disclosure relates to afield stage lighting, in particular to an LED projection lamp.

BACKGROUND

An LED lamp is a chip of electroluminescent semiconductor material that is fixed to a bracket by silver glue or white glue, and then the chip is connected with a circuit board via silver wires or gold wires. And the chip is sealed with epoxy resin around to protect internal core wires. Finally, a shell is installed to complete the LED lamp, so the LED lamp has good shock resistance. The LEDs are capable of directly emitting red, yellow, blue, green, blue, orange, purple, and white light. There are many types of LED lamps, and LED star projection lamps also belong to them, An LED star projection lamp is a decorative lighting device that projects countless stars or snowflakes on walls, ceilings, and lawns. The LED star projection lamp is used indoors, such as KTV boxes, or outdoors, such as courtyards, lawns, and on plants, which creates an atmosphere and decorate a landscape, and has a very wide range of applications in life. However, there are some problem exist in the conventional LED star projection lamp, which are set as follows:

When the conventional star projection lamp is in use, there is a projection phenomenon that causes more and clear patterns to be unable to be projected with fewer light sources, so that a richer dance or starry sky effect cannot be formed. In addition, the projected patterns are unable to be changed, which makes it impossible to project using different motifs.

When the conventional star projection lamp is in use, water ripples cannot be directly projected and imaged in a moving or static state, thus additional components are required for coordinated use, which makes an assembly cumbersome and complicated, and further makes the star projection lamp large in volume.
