Beautiful characters, figures and animation can be presented, and the shadow effect is beautiful.
Description
Technical Field
The invention relates to the technical field of lamps, in particular to a mini laser lamp.
Background
The laser emits laser light with extremely small divergence, only about 1.2 milliradian and close to parallel. The laser is applied to buildings, parks, squares, theaters and the like, and can attract people as far as several kilometers away by utilizing the non-divergence and long range of laser beams. However, the existing laser lamp is often monochrome, and the color is not rich enough, so that beautiful characters, figures and animation effects are not easy to present.
Disclosure of Invention
The application provides a mini laser lamp, through set up the grating pattern ingeniously in mini laser lamp, can present beautiful characters, figure, animation, and its shadow effect is beautiful.
The application provides a mini laser lamp, which comprises a front cover and a rear shell, wherein a first grating pattern sheet is arranged on the front cover, a circuit board, a laser light emitting diode, a speed reducing motor and a gear box are arranged in the shell, the circuit board is electrically connected with the speed reducing motor and the laser light emitting diode, the speed reducing motor is connected with the gear box through a rotating shaft, and the speed reducing motor drives a gear assembly in the gear box to rotate; the gear assembly is provided with a hollow cavity for placing a laser light-emitting diode, the end part of the hollow cavity is provided with a second grating pattern sheet, and the second grating pattern sheet can rotate along with the rotation of a gear of the gear assembly; the laser light emitted by the laser light emitting diode penetrates through the rotating second grating pattern sheet and then penetrates through the first grating pattern sheet to be emitted.
In some embodiments, the first and second grating pattern sheets are each provided with at least two sheets.
In some embodiments, the mini laser lamp is in the shape of a bulb, and the rear shell is provided with a bulb interface.
According to the above embodiment, since the laser light emitted from the laser light emitting diode first passes through the rotating second grating pattern sheet and then passes through the first grating pattern sheet to be emitted, different patterns can be arranged on the second grating pattern sheet and the first grating pattern sheet, so that the laser light emitted from the mini laser lamp can present different characters, graphics and animation, and the light and shadow effect is beautiful.

Wherein like elements in different embodiments are numbered with like associated elements. In the following description, numerous details are set forth in order to provide a better understanding of the present application. However, those skilled in the art will readily recognize that some of the features may be omitted or replaced with other elements, materials, methods in different instances. In some instances, certain operations related to the present application have not been shown or described in detail in order to avoid obscuring the core of the present application from excessive description, and it is not necessary for those skilled in the art to describe these operations in detail, so that they may be fully understood from the description in the specification and the general knowledge in the art.
The numbering of the components as such, e.g., "first", "second", etc., is used herein only to distinguish the objects as described, and does not have any sequential or technical meaning. The term "connected" and "coupled" when used in this application, unless otherwise indicated, includes both direct and indirect connections (couplings).
Referring to fig. 1-3, the present application provides a mini laser lamp, which includes a front cover 5 and a rear housing 1, wherein the front cover 5 is provided with a first grating pattern sheet 51, a circuit board 2, a laser light emitting diode 3, a reduction motor 6 and a gear box 4 are arranged in the housing, the circuit board 2 is electrically connected with the reduction motor 6 and the laser light emitting diode 3, the reduction motor 6 is connected with the gear box 4 through a rotating shaft, and the reduction motor 6 drives a gear assembly 46 in the gear box 41 to rotate; the gear assembly 46 is provided with a hollow cavity 43 for placing the laser light emitting diode 3, the end of the hollow cavity 43 is provided with a second grating pattern sheet 41, the end of the hollow cavity 43 extends out of the surface of the gear box 4, and the second grating pattern sheet 41 can rotate along with the rotation of the gear 44 of the gear assembly 46; the laser light emitted from the laser light emitting diode 3 is emitted after passing through the rotating second grating pattern sheet 41 and then the first grating pattern sheet 51. Wherein, the first grating pattern sheet 51 is opposite to the second grating pattern sheet 41, and the front cover 5 and the gear box 41 are provided with corresponding hole positions so as to position the mounting positions of the first grating pattern sheet 51 and the second grating pattern sheet 41.
In some embodiments, the first and second grating pattern sheets 51 and 41 are each provided with at least two sheets.
In some embodiments, the mini laser lamp is in the shape of a bulb, and the rear shell is provided with a bulb interface.
The present invention has been described in terms of specific examples, which are provided to aid understanding of the invention and are not intended to be limiting. For a person skilled in the art to which the invention pertains, several simple deductions, modifications or substitutions may be made according to the idea of the invention.
