Referring to fig. 4 and 5, the mask 100 includes a base plate 1 and a projection 2. The face mask 100 is connected with the lighting assembly 201 through the substrate 1, and the protruding part 2 is covered on the lighting assembly 201 of the decorative lamp 200, so that the light source can project patterns of various shapes after penetrating through the protruding part 2 of the face mask 100, thereby playing roles of decoration and beauty.

The base plate 1 is flat and is used for connection to the lighting assembly 201. The lower end of the substrate 1 is provided with a connecting structure 11 for connecting with the housing of the decorative lamp 200.

The protruding part 2 comprises a side wall 21 and a prismoid 22, and the protruding part 2 is arranged at the central position of the substrate 1 and protrudes above the substrate 1, namely, protrudes towards the direction of the installation foundation. The protruding portion 2 further comprises an accommodating cavity 23, and the protruding portion 2 is used for covering the LED lamp beads 2012 of the lighting assembly 201, so as to accommodate the LED lamp beads 2012 in the accommodating cavity 23.

The side wall 21 extends vertically upward from the substrate 1, and the side wall 21 has a plurality of wall surfaces 211, and the number of the wall surfaces 211 corresponds to the inclined surface 222 of the prism 22. Lateral wall 21 is used for improving the height between terrace with edge 22 and the base plate 1 to make to have the contained angle between terrace with edge 22 and the LED lamp pearl 2012, guarantee that terrace with edge 22 can be more abundant accept that LED lamp pearl 2012 has the irradiation of the light of intensity, avoid light source intensity not enough.

The prism table 22 includes a central plane 221, an inclined plane 222 and a pattern portion 223, the prism table 22 is a polygonal prism table, the central plane 221 is the upper bottom surface of the prism table 22, the inclined plane 222 is the side surface of the prism table 22, the side surface extends from the central plane 221 to the substrate 1 to the connecting side wall 21 and is circumferentially arranged around the central plane 221, and the number of the inclined planes 222 corresponds to the number of the side surfaces of the prism table 22. The central plane 221 and the inclined plane 222 are provided with a pattern portion 223, and the pattern 2231 on the pattern portion 223 is projected on the installation base after being irradiated by the lighting assembly 201.

In one embodiment of the present application, the frustum 22 is a regular octagonal frustum, the central plane 221 is a regular octagonal frustum, the number of the inclined planes 222 is eight, the wall surfaces 211 of the side walls 21 and the inclined planes 222 are arranged in a one-to-one correspondence, eight wall surfaces 211 are also provided, and the bottom of the inclined planes 222 is connected to the top end of the side walls 21, that is, the lower bottom surface of the regular octagonal frustum coincides with the upper end surface of the side walls 21.

As shown in fig. 6, the inclined plane 222 is obliquely arranged, because the frustum 22 is a regular octahedral frustum, the upper bottom surface is parallel to the lower bottom surface, and the lower bottom surface is parallel to the substrate 1, an inclination angle 224 is formed between the inclined plane 222 and the substrate 1, i.e., the inclination angle of the frustum 22, the angle of the inclination angle is 35 ° to 55 °, and because the lampshade 100 is covered on the LED lamp beads 2012, when the light emitted by the LED lamp beads 2012 irradiates the inclined plane 222, the size of the light spot projected on the ceiling and the distortion degree of the light spot are affected by the angle of the inclination angle 224; if the angle of the tilt angle 224 is small, the flare becomes small, and if the tilt angle 224 is large, the spot distortion increases, and an excessively large or excessively small tilt angle 224 affects the pattern quality, so that the angle of the tilt angle 224 is limited to 35 ° to 55 °, and a preferable pattern quality can be obtained.

Referring to fig. 7, the bottom of the inclined surface 222 is connected to the top end of the sidewall 21, a light transmission angle 225 is formed between a connecting line between an end point of the inclined surface 222 close to the sidewall 21 and the center point of the illumination assembly 201 and the central axis of the frustum 22, and the angle of the light transmission angle 225 is 0-65 °. Because the light intensity of the LED lamp beads 2012 is lamber distribution, and the half width is generally 60 °, the light energy exceeding the range of 70 ° is small, the light source intensity is not enough, and the projected pattern on the ceiling is not bright, which affects the imaging quality. Therefore, the angle of the light transmission angle 225 is set to 0 to 65 degrees, so that the light transmitted through the pattern part 223 has enough light intensity, and the projected pattern after being irradiated to the ceiling is clear and bright. The side wall 21 is arranged to raise the height of the prism table 22, so that the included angle at which the prism table 22 can receive light is less than or equal to 65 °, the angle of the light transmission angle 225 is limited, and the excessive angle of the light transmission angle 225 is avoided.

The pattern portion 223 includes at least two patterns 2231, and the pattern portion 223 is provided on the prism table 22 and provided through the prism table 22. The number and shape of at least two patterns 2231 may be the same or different, and are not limited herein, but the same pattern 2231 may be disposed on either the central plane 221 or one of the inclined planes 222, and not on both different sides of the prism 22. The light source in the housing cavity 23 emits light, a part of the light strikes the side wall 21 of the mask 100 and the non-pattern portion 223 of the protrusion portion 2, and is absorbed or reflected, and another part of the light passes through the pattern portion 223, and falls on the ceiling, so as to project a pattern on the ceiling, and project a light and shadow pattern corresponding to the pattern portion 223.

The projected area of pattern 2231 on the prism table 22 decreases gradually from the inner surface 226 to the outer surface 227, in other words, the area of the cross-section of pattern 2231 taken along a direction parallel to the center plane 221 decreases gradually along a direction inward from the interior of the prism table 22, with the cross-sectional area of the pattern inner surface being the largest and the cross-sectional area of the pattern outer surface being the smallest. The pattern 2231 forms a sloped draft surface 2232 between the inner surface 226 and the outer surface 227, and a draft angle 2233 between the draft surface 2232 and a vertical plane perpendicular to the inclined surface 222, the draft angle 2233 being greater than the angle of the sloped angle 224. Similarly, how the draft angle 2233 of the pattern 2231 disposed on the inclined surface 222 is defined can be known, and will not be described herein. With the thus arranged pattern 2231, when light is irradiated from the inside of the convex portion 2, due to the existence of the draft angle 2233, the light received by the pattern 2231 at the inner surface 226 is converged on the outer surface 227, that is, the light of the pattern inner surface with the largest cross-sectional area is converged on the pattern outer surface with the smallest cross-sectional area, so that the convergence of light is realized, the light intensity is increased, the projected pattern is clear, and glare can be reduced. And the draft angle 2233 is arranged so that the mask 100 formed by injection molding and integrated molding is convenient for demolding.

Referring to fig. 10, a projection effect diagram corresponding to the mask 100 in the embodiment of the present application shown in fig. 1 is shown, in which the pattern portion 223 is composed of sparse stars and circles, and the projected image on the ceiling corresponds to sparse stars and dots.

The lower end of the base plate 1 of the mask 100 is further provided with a connecting structure 11, and the mask 100 is connected with the shell through the connecting structure 11. The housing is a decorative housing, so that the decorative lamp 200 looks more beautiful. In another embodiment of the present application, an illumination unit may be disposed inside the housing, so that not only the illumination module 201 can project the light to the ceiling above the decoration lamp 200, but also the illumination module can illuminate the light downward.

The lighting assembly 201 comprises a mounting plate 2011 and LED lamp beads 2012 arranged on the mounting plate 2011, the mounting plate 2011 is detachably connected with the substrate 1, and the LED lamp beads 2012 are accommodated in the accommodating cavity 23 formed by the protruding part 2 of the mask 100. The LED lamp beads 2012 are an independent lamp bead and located in the center of the mounting plate 2011, and after being accommodated in the accommodating cavity 23, the vertical distances from the LED lamp beads 2012 to the inclined surfaces 222 of the face mask 100 are equal. Thereby ensuring that each ramp 222 receives the same intensity of light. Meanwhile, the vertical distance between the LED lamp beads 2012 and the ceiling is not more than 200mm, because the LED lamp beads 2012 are only single lamp beads, the luminous intensity is limited, and therefore the vertical distance between the LED lamp beads 2012 and the ceiling is not too large, and the projected pattern is clear and bright.

In a preferred embodiment of the present application, the lighting device further comprises a lighting device, wherein the lighting device comprises a lighting lamp, a mounting structure and a decorative lamp 200, the lighting lamp and the decorative lamp 200 are mounted on the mounting structure, and the mounting structure is mounted on a mounting foundation, namely a ceiling.
