Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a projection lamp. Background Art

[0002] The projection lamp uses a high-brightness LED lamp as a light source. The light passes through the projection lampshade to project the pattern onto the wall and ceiling. At the same time, the light will also be seen through the transparent ring pattern to form an aperture, and the light will be projected around the product to form a dazzling halo. Its working principle is to convert electrical energy into light energy, and control and adjust the light through a series of optical technologies, so as to project clear and bright images or text.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-5 A projection lamp comprises a base 1, a transparent ring 2 is fixedly installed on the periphery of the base 1, an LED lamp group 3 is fixedly installed on the top of the base 1, a torus structure is arranged between the LED lamp group 3 and the base 1, the radius of the torus structure is smaller than that of the LED lamp group 3, the torus structure is used as the rotation axis of the turntable 4, the PCB of the LED lamp group 3 above it is used to limit the turntable 4, the torus structure and the base 1 are integrally formed, the turntable 4 is movably sleeved on the torus structure, the bottom of the turntable 4 is provided with a gear ring 5, and the gear ring 5 is connected with the gear 8, the gear 8 is fixedly mounted on the power output shaft of the motor 9, the motor 9 is fixedly mounted on the base 1, the projection lamp cover 6 is mounted on the turntable 4, the upper shell 7 is mounted on the transparent ring 2, the turntable 4 and the projection lamp cover 6 are both located inside the upper shell 7, when the lamp tube irradiates the upper shell 7, due to the diffuse reflection of light, part of the light is rebounded to the transparent ring 2, because the transparent ring 2 is made of transparent material, after receiving light, the light is diffusely reflected inside, and the transparent ring 2 also emits a lighting effect;

[0025] The base 1 is fixedly mounted inside the lower shell 13, a button 11 is snap-fitted on the lower shell 13, the button 11 is electrically connected to the control IC 10, the control IC 10 is fixedly mounted inside the lower shell 13, a power module 12 is also fixedly mounted inside the lower shell 13, a battery compartment 14 is provided at the bottom of the lower shell 13, and a matching 15 is installed on the battery compartment 14.

[0026] Furthermore, various shapes and patterns are printed on the projection lamp cover 6 .

[0027] In the present invention, the inner wall of the transparent ring 2 is provided with a plurality of first protrusions 201 , and the outer wall of the bottom end of the upper shell 7 is provided with a plurality of installation openings 701 , and the first protrusions 201 correspond to the installation openings 701 one by one and match each other.

[0028] In the present invention, notches 301 are provided on both sides of the LED lamp group 3 , and a third protrusion 501 is provided on the inner ring of the gear ring 5 . The notches 301 and the third protrusion 501 match each other.

[0029] In the present invention, a second protrusion 401 is disposed at the edge of the turntable 4 , an outer edge 601 is disposed at the edge of the port of the projection lamp cover 6 , and a plurality of notches 602 corresponding to and matching the second protrusion 401 are disposed on the outer edge 601 .
