Abstract

The invention discloses a swinging slide projection lamp which mainly adopts the structure that a light-transmitting lampshade is arranged at the front end of a lamp housing; a power supply unit and a swinging projection mechanism are arranged in the lamp housing; after light emitted from an LED lighting device of the swinging projection mechanism passes through a collecting lens plate, a slide and a convex lens plate, a patterned light shadow is projected by the light-transmitting lampshade; and furthermore, a motor drives the convex lens plate to rotate, so that convex lenses of the convex lens plate rotate to change positions relative to pattern units of the slide, and then the projected patterned light shadow has a rotating and changing light effect. Meanwhile, the motor further drives a transmission gear, the transmission gear drives an eccentric guide gear to rotate, and an eccentric column of the eccentric guide gear performs linear reciprocating motion in the lamp housing, so that the whole swinging projection mechanism can be guided to swing from one side to another, the projected rotating and changing patterned light shadow can further have a side-to-side swinging dynamic changing effect, and the floating range of the project patterned light shadow can be enlarged.

Description

technical field

[0001] The invention relates to a projection lamp, in particular to a swinging slide type projection lamp capable of producing patterned dynamic lighting effects. Background technique

[0002] At present, in places such as performance stages, in order to create a joyful and colorful atmosphere, in terms of lighting, related companies have designed projection lights that can produce dynamic lighting effects. The composition and structure of the existing stage projection lamp mainly includes a motor and a projection lamp. The projection lamp mainly installs a light source module and a light output lens inside a lamp housing, and uses the light source module to emit light through the light lens. The projection changes, combined with the rotation of the motor-driven projection lamps, and the light passes through the patterned slides (commonly known as film sheets), to produce patterned dynamic lighting effects.

[0003] However, the composition and structure des...
