The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

The utility model relates to a lamp structure, which comprises a lamp holder 100, a light guide cover 200 and a light emitting element 400.

As shown in fig. 1 and 2, the lamp socket 100 may have an elongated structure as shown. The light guide cover 200 is mounted on the lamp holder 100 in a covering manner, and a containing cavity 300 is formed between the interior of the light guide cover 200 and the lamp holder 100. The light emitting element 400 is installed in the receiving chamber 300. The light guide cover 200 is made of a light-transmitting material, and light generated by the light emitting element 400 is radiated outwards through the light guide cover 200. Wherein, the outer surface of the light guide cover 200 has a first light emitting surface 210 and a second light emitting surface 220. The space where the lamp structure is entirely located has a first direction and a second direction. The first direction is the front-back direction in the figure with the direction of the figure; the second direction is the left-right direction in the drawing, and the first direction and the second direction are perpendicular to each other. The first light emitting surface 210 faces upward, and the light passes through the first light emitting surface 210 and irradiates forward along the first direction. The second light emitting surface 220 extends in an arc shape from the first direction to the second direction to form an arc shape, that is, the second light emitting surface 220 is turned from the front direction to the left direction in the illustrated direction. In actual use, the surface of the product is planar by placing the lamp holder 100 in a place where illumination is desired or on the surface of the product. The second light emitting surface 220 is adjacent to the surface of the product. The light emitting element 400 may be an LED light bar, etc., and the light emitting element 400 generates light, part of which irradiates forward along the first direction from the first light emitting surface 210, and part of which irradiates outward from the second light emitting surface 220. Since the second light emitting surface 220 is an arc surface, the light rays are divergently irradiated in a fan shape after passing through the second light emitting surface 220, and a part of the light rays are projected onto the surface of the product along the second direction. By utilizing the cooperation of the first light emitting surface 210 and the second light emitting surface 220 of the light guide cover 200, the space range between the front of the product and the surface of the product is covered during illumination, so that the illumination of an object in front of the product is ensured, the illumination of the surface of the product adjacent to a lamp structure is ensured, and a good lighting effect is integrally achieved.

In some embodiments, as shown in fig. 1 and 2, the second light emitting surface 220 and the first light emitting surface 210 are engaged with each other. The second light emitting surface 220 extends from one side of the first light emitting surface 210, and the first light emitting surface 210 and the second light emitting surface 220 are integrated, so that no lighting blind area can appear in the space covered by lighting during lighting.

The arc-shaped extension of the second light emitting surface 220 may be that the entire second light emitting surface 220 is curved. In some embodiments, as shown in fig. 1 and 2, the second light emitting surface 220 includes a first segment surface 221 and a second segment surface 222. The first segment surface 221 extends from one side of the first light emitting surface 210, and the first segment surface 221 extends gradually in an arc surface, and the second segment surface 222 extends from one side of the first segment surface 221 away from the first light emitting surface 210. The second section 222 is a plane, and the second section 222 is perpendicular to the second direction. Spatially, the first light-emitting surface 210 and the second segment surface 222 are perpendicular to each other. The first segment surface 221 covers the transitional illumination range between the first light-emitting surface 210 and the second segment surface 222, and the second segment surface 222 ensures that part of light is projected onto the surface of the product along the second direction.

In some embodiments, as shown in fig. 1 and 2, the light guide cover 200 further includes a third light emitting surface 230 thereon. The third light emitting surface 230 may be a curved surface or a flat surface. In the present embodiment, the third light emitting surface 230 extends out of the first light emitting surface 210 from a side away from the second light emitting surface 220 in a plane. The third light emitting surface 230 may be linearly extended in the first direction such that the third light emitting surface 230 is perpendicular to the second direction; or the third light emitting surface 230 extends obliquely in the first direction, and the third light emitting surface 230 forms an intersecting angle with the second direction, which is not right angle. Part of the light generated by the light emitting element 400 is projected outward from the third light emitting surface 230. The third light emitting surface 230 further increases the irradiation range, further expands the irradiation range to the outside of the product, and improves the lighting effect.

In some embodiments, as shown in fig. 1 and 2, the inside of the light guide cover 200 is hollow, and the extending direction of the inner wall of the light guide cover 200 is similar to the extending direction of the outer wall thereof. I.e., the inner wall of the light guide cover 200 extends in a cambered surface. The inner wall of the light guide cover 200 is matched with the lamp holder 100 to form a containing cavity 300. The inner wall is formed in a cambered surface shape, so that the overall thickness of the light guide cover 200 is reduced, and the light permeability is improved. When the light irradiates the inner wall of the light guide cover 200, certain refraction is formed, and the refraction coefficient of the air in the accommodating cavity 300 is inconsistent with the refraction coefficient of the material of the light guide cover 200, so that the light is more uniform when passing through the light guide cover 200, and meanwhile, the visual effect of the light of each lamp bead on the light emitting element 400 can not be seen from the outside of the light guide cover 200.

In some embodiments, as shown in fig. 1 and 2, the interior of the lamp socket 100 is provided with a boss 110. In this embodiment, the lamp holder 100 is in a strip shape, the boss 110 protrudes forward from the lamp holder 100, and the boss 110 extends along the length direction of the lamp holder 100. The left and right sides of the boss 110 are spaced apart from the left and right sides of the lamp socket 100 by a certain interval, and the interval constitutes a slot 130. The light guide cover 200 extends in a long shape corresponding to the lamp socket 100. The plugging sections 240 extend rearward along the first direction on the left and right sides of the light guide cover 200, respectively. The shape of the plug section 240 is adapted to the socket 130. The plugging sections 240 on the two sides are plugged into the slots 130 on the two sides respectively for positioning and installation. The light emitting element 400 is mounted on the boss 110. The light emitting element 400 may be fixed to the boss 110 by means of adhesion, screw locking, or the like.

Further, the inside of the boss 110 is provided to be hollow. The rear sidewall of the lamp socket 100 is located opposite to the boss 110. The rear sidewall of the lamp socket 100 is provided with a mounting hole 120, and the front sidewall of the boss 110 is correspondingly provided with a mounting hole 120. The light emitting element 400 may be fixed to the boss 110 through the mounting hole 120 on the boss 110 using a screw or the like, which simultaneously fixes the lamp socket 100 to a product through the mounting hole 120 on the lamp socket 100. The wires of the light emitting element 400 may also be led out of the lamp socket 100 through the mounting hole 120.

The utility model also relates to a mirror cabinet, which comprises a cabinet body 500, a mirror body 600 and the lamp structure. As shown in fig. 3, 4 and 6, the mirror 600 may be mounted on a cabinet door of the cabinet 500, which is a part of the cabinet 500. The lamp structure is fixed to the cabinet 500 by the lamp socket 100 and is located on the periphery of the mirror 600. The side of the second light emitting surface 220 away from the first light emitting surface 210 is close to or flush with the mirror surface 610 of the mirror body 600. At least a portion of the light is refracted and irradiated onto the mirror surface 610 of the mirror body 600 after passing through the second light emitting surface 220. When the face-cleaning and makeup mirror is used, part of light irradiates forward on the body surface of a user, and part of light irradiates on the mirror surface 610, so that the space in front of the mirror surface 610 is fully lighted by the mirror surface 610, the user can conveniently and clearly check the face details, and the face-cleaning and makeup mirror is beneficial to the face cleaning and makeup operations of the user.

In some embodiments, as shown in fig. 3 and 4, the light structures are arranged in a bar around the periphery of the mirror 600. The lamp structure is fixed to the cabinet 500 by the lamp socket 100. The mirror body 600 may have a rectangular or oval shape, and the light guide cover 200 extends in a rectangular or oval shape. The lamp socket 100 is integrally injection molded, and can well control the overall size of the lamp structure. The light guide cover 200 is formed by integral injection molding, and some light guide covers 200 are arranged in rectangular shapes, so that the integral molding can avoid splicing gaps at corners and can also avoid the problem of dark corners at the corners.

The connector 700 includes a first post segment 710 and a second post segment 720. The first column section 710 is in plug connection with the lamp holder 100, and the second column section 720 is in plug connection with the cabinet 500. The lamp holder 100 and the cabinet 500 are quickly connected by the connecting piece 700 without the assistance of external tools such as a screwdriver, so that the lamp holder 100 and the cabinet 500 can be quickly installed, the labor time is saved, the connecting piece 700 is hidden between the lamp holder 100 and the cabinet 500, external components such as screws and fixing blocks can not be seen in appearance, and the attractive effect of the product is improved.

Specifically, the first column section 710 and the second column section 720 are provided with a plurality of chucks 730, and each chuck 730 is distributed layer by layer along the axial direction of the first column section 710 and the second column section 720. The shape of the chuck 730 can take a variety of forms. For example, the chuck 730 has a circular truncated cone shape, and the circular truncated cone-shaped chuck 730 has a large rounded end 732 and a small rounded end 731. The large rounded end 732 faces toward the middle of the connector 700, where the middle of the connector 700 is the transition between the first post segment 710 and the second post segment 720.
