Insertion type pattern projection lamp

Abstract

The invention discloses the field of projection lamps, in particular an insertion type pattern projection lamp. The insertion type pattern projection lamp comprises a lamp body and an adapter; the lamp body consists of a front lamp cover, a lamp body and a back lamp cover; a PCB is arranged in the back lamp cover; an imaging lens bracket, an imaging lens, a lens bracket, a support column, a flat convex lens, a lens pressing plate, an LED module and a motor are arranged in the lamp body; the lamp body is provided with a bracket, a film and a pressing plate; and the bracket and the lamp body areof detachable structures. As the bracket and the lamp body are of the detachable structures, and the film is mounted on the bracket, the problem of single pattern in the prior art is convenient to manually improve according to replacement of the film; and the film can bear high temperature, so that the insertion type pattern projection lamp has the advantages of various patterns and excellent high-temperature resistance.

Description

technical field [0001] The invention discloses the field of projection lamps, and more specifically discloses an insert-type pattern projection lamp. Background technique [0002] Existing projection lamps that can irradiate patterns use frog-eye convex mirrors to gather light, and then pass the gathered light through a patterned film, so that the projection lamps irradiate patterns, but the frog-eye convex mirrors in such projection lamps There is a problem of poor light efficiency. In order to make the pattern clear, high-power projection lamps are often used artificially. Although the pattern is clear, the pattern is relatively simple, and there is no air flow inside the high-power projection lamp, which will cause internal damage. The heat of the projection lamp cannot be dissipated, resulting in poor cooling effect, and at the same time, the internal temperature of the projector lamp will deform the pattern film, thereby shortening the service life of the pattern film. ...

AI Technical Summary

Problems solved by technology

[0005] A plug-in pattern projection lamp, including a lamp body and an adapter, the lamp body is composed of a front lamp cover, a lamp body and a rear lamp cover, a PCB board is arranged inside the rear lamp cover, and the PCB board and the adapter are electrically connected connection, the lamp body is provided with an imaging lens holder, an imaging lens, a lens holder, a support column, a plano-convex lens, a lens pressing plate, an LED assembly and a motor, and the motor and the LED assembly are electrically connected to the PCB board, and the The motor is located at the rear side of the LED assembly, the lens pressing plate is located at the front side of the LED assembly, the lens pressing plate is sleeved on the plano-convex lens, the plano-convex lens is installed on a support column, and the support column is installed on the lens holder , the imaging lens is installed on the lens bracket, the lamp body is provided with a bracket, a film and a pressure plate, the bracket and the lamp body are detachable structures, the film is installed on the bracket, and the film is located on Between the pressure plate and the bracket, the bracket is buckled and connected with the pressure plate, and the pressure plate is located on the front side of the imaging lens bracket. Since the bracket and the lamp body are detachable structures, the film sheet is installed on the bracket, so that It is convenient to manually replace the film sheet according to the need to improve the problem of single pattern in the prior art, and the film sheet can withstand high temperature, so that the plug-in pattern projection lamp not only has the advantage of not only a single pattern, but also has the advantage of high temperature resistance
