The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0030] Please refer to Figure 1-7 As shown, the embodiment of the utility model provides an LED linkage induction magnetic night light 100, which includes a fastener 110, an upper cover 120, a housing 130, a light guide plate 140, a PCBA 150, and a light source 160.

[0031] The light-transmitting upper cover 120 and the housing 130 can be pressed against the opposite ends of the light guide plate 140 by the fastener 110, and a cavity for accommodating the PCBA 150 and the light source 160 is formed after assembly;

[0032] There is a gap between the light guide plate 140 and the light source 160 to avoid damage to the light source. A plurality of light sources 160 are distributed on the PCBA 150 and are electrically connected thereto.

[0033] The LED linkage induction magnetic night light 100 provided by the utility model uses the fastener 110 to press the light-transmitting upper cover 120 and the housing 130 against the opposite ends of the light guide plate 140, and allows the PCBA 150 and the light source 160 to be in the cavity formed after the upper cover 120, the housing 130 and the light guide plate 140 are assembled, so that the LED linkage induction magnetic night light 100 can avoid directly touching the light source during the assembly process, thereby protecting the light source. Compared with the traditional assembly structure, the direct assembly of the lamp housing and the lampshade can easily cause damage / damage to the light source by touching and pressing the light source. Therefore, the present embodiment effectively improves the technical defects caused by the direct assembly of the lamp housing and the lampshade.

[0034] In detail, the light-transmitting upper cover 120 and the housing 130 increase the irradiation range of the LED linked induction magnetic night light 100 .

[0035] Furthermore, the light sources 160 mentioned above are distributed on the PCBA 150. In a specific implementation, the arrangement of the light sources 160 can be, for example, a circular array arrangement, a rectangular array arrangement, or an irregular array arrangement. It should be understood that the arrangement of the light sources 160 is not limited by the present invention.

[0036] In addition, the light source 160 mentioned above can be implemented using LED lamp beads.

[0037] It should be noted that the fastener 110 may be, for example, a screw.

[0038] In this specific embodiment, a through hole 141 is formed on the light guide plate 140, and grooves 142 are formed around the through hole 141 at the opposite ends thereof, so that a portion of the upper cover 120 and the housing 130 can be embedded in the groove 142 through the fastener 110. A convex ring 143 is extended on the light guide plate 140 toward the PCBA 150 and the light source 160 and is located between the groove 142 and the through hole 141, and there is a gap between the convex ring 143 and the light source 160.

[0039] In order to allow a portion of the upper cover 120 and the housing 130 to be embedded in and pressed against the groove 142 , a fastener 110 is provided to allow the three to be assembled, and the assembled contact surfaces can be tightly matched.

[0040] In order to guide the irradiation direction of the light source 160, the convex ring 143 is arranged to extend above the light source 160 and to have a gap therebetween. In the first aspect, this prevents the convex ring 143 from directly contacting the light source 160 and causing contact damage / damage. In the second aspect, this guides the light source 160 to a certain extent.

[0041] In this specific embodiment, a Boss column is provided on the upper cover 120 , which extends toward the housing 130 , passes through the PCBA 150 , and is located on one side of the light source 160 ; the fastener 110 passes through the housing 130 and is threadedly connected to the Boss column.

[0042] In order to assemble the upper cover 120 and the housing 130 at the opposite ends of the light guide plate 140, the fastener 110 is threadedly connected to the BOSS column. Where the Boss column interferes with the PCBA 150 in the extension direction, an air avoidance hole (revealed in the figure but not marked) is opened on the PCBA 150 for the Boss column to pass through, so that the fastener 110 and the Boss can be better assembled, which reflects the rationality of the design of the structure and the rational assembly between structures.

[0043] In this specific embodiment, the shell 130 is provided with a plurality of bone positions 131 for placing the PCBA 150 and a screw column 132 located on one side of the bone position 131. The upper end surfaces of the plurality of bone positions 131 are flush with the upper end surfaces of the screw column 132. The PCBA 150 is installed on the shell 130 by means of screws (revealed but not marked in the figure) passing through the PCBA 150 and being threadedly connected with the screw column 132.

[0044] In order to enable the PCBA 150 to be installed on the housing 130, a plurality of bone positions 131 for supporting and placing the PCBA 150 are provided. In order to enable the PCBA 150 to be fixed on the housing 130, screws and screw columns 132 are used for assembly.

[0045] In this specific embodiment, the housing 130 is provided with a through hole 133 for embedding the magnet 170, and the magnet 170 is located below the PCBA 150; it also includes a magnetic iron sheet 180 magnetically connected to the magnet 170, and the magnetic iron sheet 180 is located outside the housing 130; a double-sided adhesive 190 is attached to the magnetic iron sheet 180. This facilitates the installation of the LED linkage induction magnetic night light 100 and the wall or other objects to be assembled therewith.

[0046] In some embodiments, a through hole 133 is provided on the housing 130 for embedding the magnet 170, the magnet 170 is located below the PCBA 150, and the magnet 170 extends out of the housing 130. If the object assembled with the LED linkage induction magnetic night light 100 can be adsorbed by the magnetic pole of the magnet 170, the wall-mounted lamp is directly adsorbed on the magnetically adsorbed object by magnetic attraction. It should be understood here that the magnetically adsorbed object includes iron, steel and other materials, but is not limited thereto.

[0047] In this specific embodiment, part of the light guide plate 140 is in the cavity, and the other part extends toward the outer periphery of the upper cover 120 and the housing 130, and the light guide plate 140 has at least two light-transmitting surfaces; in order to increase the illumination range of the LED linkage induction magnetic night light 100, another part of the light guide plate 140 extends toward the outer periphery of the upper cover 120 and the housing 130 to expand the illumination range. In addition, by utilizing the excellent light transmittance of the material of the light guide plate 140, the light guide plate 140 has at least two light-transmitting surfaces.

[0048] The area of ​​the light guide plate 140 in the cavity is smaller than that outside the cavity. The portion of the light guide plate 140 in the cavity can be understood as a convex ring 143, which extends in the cavity toward the light source 160 and is located above the light source 160, so that there is a gap between the convex ring 143 and the light source 160.

[0049] In this specific embodiment, a lithium polymer battery 200 is also electrically connected to the PCBA 150, and the lithium polymer battery 200 is located in the through hole 141 to provide power for the LED linkage induction magnetic night light 100.

[0050] In this specific embodiment, the upper cover 120 and the housing 130 are both made of ABS material. The light-transmitting ABS material is used to increase the illumination range of the LED linkage induction magnetic night light 100.

[0051] In this specific embodiment, the light guide plate 140 is made of acrylic material, and the excellent light transmittance of the acrylic material itself is utilized to make the light irradiated by the LED linkage induction magnetic night light 100 bright.

[0052] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
