And because the first grating mirror 11 is provided with a plurality of first grating patterns uniformly distributed in the ring, under the drive of the first driving device 12, the plurality of first grating patterns are aligned with the second grating pattern one by one as they rotate. A light fixture 31 is superimposed on the light projection path, so that the light pattern formed by the light projected by the first light fixture 31 is transformed with the rotation of the first grating lens 11, and the light pattern transformation is diversified; in addition, the second grating lens 21 The rotation can also be realized under the driving of the second driving device 23 , so that the second grating pattern arranged on the second grating lens 21 can also realize rotation when superimposed on the first grating pattern, and the light pattern becomes dynamic, and the light effect is excellent.

It should be noted that, in this embodiment, the second grating lens 21 is located between the first grating lens 11 and the first lamp 31, that is to say, the light projected by the first lamp 31 passes through the second grating lens 21 sequentially.

The bevel teeth can be directly or indirectly arranged on the first grating lens 11, the bevel teeth being directly arranged on the first grating lens 11 means that the outer edge of the first grating lens 11 is cut out of the bevel teeth during processing; The fact that the bevel teeth are indirectly disposed on the first grating lens 11 means that the first grating lens 11 is sheathed in an accommodating ring, and the outer peripheral wall of the accommodating ring is provided with bevel teeth.

In addition, as an equivalent transformation of this embodiment, the first driving device 12 can also adopt a transmission method of a worm gear, specifically: the first driving device 12 includes a knob 81 and a first connecting member 82, and the knob 81 is connected to the first connecting member 82. The first connecting piece 82 is fixedly connected, the first connecting piece 82 is provided with a worm part, and the outer edge of the first grating lens 11 is provided with a worm gear part matched with the worm part.

Embodiment eight

Please refer to FIG. 16 and FIG. 17 , the eighth embodiment of the present invention is based on the first embodiment of the specific structure of the first driving device 12 in the lighting module 100 and the driving of the first grating glass 11 by the first driving device 12 Another technical solution proposed by the above method: the first driving device 12 includes a rotating member 86 with a hollow structure with openings at both ends, the first grating lens 11 is fixed in the rotating member 86, and one end of the rotating member 86 A transparent plate 87 is provided at the opening, and the first grating lens 11 is fixed on the transparent plate 87 by screws, glue or buckles. More specifically, in the laser lamp of this embodiment, the housing 200 of the laser lamp includes a rotatably connected front end cover and a rear end cover, the rotating member 86 is the front end cover, and the transparent plate 87 is implemented The projection lens 210 described in Example 1.

The user rotates the rotating member 86 to drive the first grating mirror 11 to rotate, which is very convenient.

It should be noted that the rotating member 86 is not necessarily the front cover of the laser lamp housing 200. In other embodiments, the laser lamp housing 200 can be arranged as a three-section structure, wherein the front section and the rear section are fixedly connected, and the middle section is placed Between the front section and the rear section, it is also feasible that the middle section is rotatably connected to the front section and/or the rear section. In this case, the middle section of the housing 200 can be regarded as the above-mentioned rotating member 86 .

To sum up, in the lighting module provided by the present invention, the light projected by the first lamp passes through the first grating pattern of the first grating lens and the second grating pattern of the second grating lens, and is projected onto the outside plane to form the light The pattern is the superposition of the first grating pattern and the second grating pattern, and the formed light pattern is more magical and dreamy. And because the first grating lens is provided with several first grating patterns uniformly distributed in the ring, under the driving of the first driving device, the several first grating patterns are superimposed with the second grating pattern one by one as they rotate, so that the first The light pattern formed by the light projected by a lamp is transformed with the rotation of the first grating lens, and the light pattern changes in diversification; in addition, the second grating lens can also be rotated under the drive of the second driving device, so that the second When the second grating pattern arranged on the grating lens is superimposed on the first grating pattern, it can also rotate, and the light pattern becomes dynamic, and the light effect is excellent. In the laser lamp provided by the present invention, since a lighting module is provided in the casing, through the joint work of the first grating assembly, the second grating assembly and the lamp assembly of the lighting module, the light pattern projected by the first lamp is the second The effect of the superimposition of the grating lens and each first grating pattern realizes the transformation and diversification of the light pattern, and the light pattern can be dynamic, and the light effect is excellent.

The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent transformations made by using the description of the present invention and the contents of the accompanying drawings, or directly or indirectly used in related technical fields, are all included in the same principle. Within the scope of patent protection of the present invention.
