The lamp body 3 is predetermined to be located at the positioning portion 13, the fixing portion 12 is aligned with the fixing hole of the lamp body 3, and the lamp body 3 is fixed to a plurality of the fixing portions 12.
[0028] like Figure 2 , Figure 3 and Figure 4As shown, the projection module 4 includes a fixing frame 41, a projection sheet 42 and a projection lamp sheet 43 arranged on the fixing frame 41. The fixing frame 41 includes a main body 411, a plurality of hooks 412 extending downward from the main body 411, and a mounting hole 413 penetrating the main body 411 from top to bottom. The hook 412 includes an extension portion connected to the main body 411 and a hook portion extending from the extension portion. The main body 411 is covered on the outside of the lamp body 3. The shading portion is arranged around the outer wall of the main body 411 to prevent light leakage from the lower end of the main body 411. The shading portion is an arc structure located on both sides of the limiting groove 22, and the shading portion at least partially contacts the outer wall of the main body 411. It can also be said that the circumference formed by the shading portion and the circumference of the main body 411 form a concentric circle. The width of the mounting hole 413 gradually decreases from bottom to top, that is, the mounting hole 413 forms a cone-shaped structure. The main body 411 is arranged in the sink 21, that is, the two are aligned up and down. The hook protrudes into the limit groove 22 and is located below the buckle 23 to prevent the projection module 4 from detaching from the turntable 2. The projection film 42 forms a fan-shaped structure in the unfolded state, and is installed in the mounting hole 413 to form a hollow conical structure, and its taper is the same as the taper of the inner wall of the mounting hole 413. The projection film 42 is installed upward in the mounting hole 413, and the fit between the projection film 42 and the inner wall of the mounting hole 413 is changed from loose fit to tight fit. The projection film 42 is attached to the inner wall of the mounting hole 413 to prevent the projection film 42 from automatically falling off the fixing frame 41. The projection film 42 includes a transparent film, a main projection area arranged on the transparent film, and an auxiliary projection area arranged around the main projection area. The transparent film serves as the bottom film of the projection film 42, and the main projection area includes a color pattern and / or a transparent pattern. The slide film 42 includes a first end 421 and a second end 422 that can be connected or detached, and an upper end surface 423 and a lower end surface 424 that connect the first end 421 and the second end 422. The first end 421 includes a base 4211 and at least one plug-in portion 4212 extending from the base 4211. The second end 422 includes a matching portion 4221 and at least one locking portion 4222 that is arranged away from the plug-in portion 4212 relative to the matching portion 4221. In this embodiment, the two plug-in portions 4212 are arranged at intervals in the vertical direction, and the two plug-in portions 4212 are buckled with the two locking portions 4222 in a one-to-one correspondence. The base 4211 and the matching portion 4221 are stacked up and down, and the base 4211 is located above the matching portion 4221, and the overlapping area of the base 4211 and the matching portion 4221 gradually decreases from bottom to top.The width of the plug-in portion 4212 is less than 1 / 2 of the width of the base portion 4211. The locking portion 4222 is configured as a slot penetrating the second end portion 422. The width of the slot is less than 1 / 2 of the width of the second end portion 422. The plug-in portion 4212 is inserted into the slot, and the plug-in portion 4212 protrudes into the inner side of the tapered projection film 42 or is exposed on the outer side of the projection film 42. The distances between the two slots and the edge of the matching portion 4221 are the same, or the distance between one of the slots and the edge of the matching portion 4221 is greater than the distance between the other slot and the edge of the matching portion 4221. The first end face of the first end portion 421 and / or the second end face of the second end portion 422 are inclined toward the central axis P of the tapered projection film 42. The contour surface of the upper end face 423 and / or the lower end face 424 is a curved surface. In this embodiment, the middle part of the upper end surface 423 and / or the lower end surface 424 is bent downward, and the two side parts of the upper end surface 423 and / or the lower end surface 424 are gradually bent upward from the middle, so that when the projection sheet 42 is rolled into a conical structure, the upper end surface 423 and the lower end surface 424 are approximately at the same height, which is convenient for adapting to the fixing frame 41. The projection light sheet 43 is installed on the fixing frame 41 and is located above the lamp body 3. The projection light sheet 43 covers the upper end opening of the conical projection sheet 42. When the light emitted by the lamp body 3 is projected onto the inner surface of the projection sheet 42, the projection sheet 42 will reflect some stray light. Since the projection sheet 42 forms a conical structure, the projection sheet 42 projects the reflected stray light downward, reducing the stray light projected upward onto the projection light sheet 43, thereby reducing the influence of the stray light on the projection effect.
[0029] In summary, the night light of the utility model has the following beneficial effects:
[0030] (1) The lamp body 3 is installed on the base 1, and the fixing frame 41 is arranged around the lamp body 3 and includes a mounting hole 413 that passes through the upper and lower surfaces thereof. The mounting hole 413 is a tapered structure that gradually becomes smaller from bottom to top; the projection film 42 is installed in the mounting hole 413, and the fit between the projection film 42 and the inner wall of the mounting hole 413 is changed from clearance fit to contact fit. The projection film 42 is attached to the inner wall of the mounting hole 413. The projection film 42 includes a transparent film, a main projection area arranged on the transparent film, and an auxiliary projection area arranged around the main projection area. The light emitted by the lamp body is projected outward through the main projection area. The projection film with a tapered structure projects stray light downward, reduces stray light projection upward, and makes the projection effect clearer. In addition, the projection film can be prevented from being reversely installed. The projection film is attached to the inner wall of the mounting hole, and the light transmittance is better.
