Description

Technical Field

[0001] The utility model relates to the technical field of lamps, and in particular to a mirror lamp with adjustable polarization angle. The mirror lamp can adjust the light direction horizontally and has an anti-glare effect. Background Art

[0002] A mirror lamp is a lamp installed in front of a mirror. When looking in the mirror, since you are facing away from the main light source in the room, in order to avoid the person being dimmed, a mirror lamp is generally installed in front of the mirror. In order to increase the brightness of the mirror, a mirror lamp with a polarizing function is generally used to make the brightness of the mirror greater than the brightness of the surrounding space. However, the existing mirror lamp cannot adjust the polarization angle, which is inconvenient for users to use. Most of the light from traditional mirror lamps is directly irradiated on the face, and the anti-glare effect is average. This product achieves the function of a mirror lamp by controlling the light and the lamp body structure, and has an excellent anti-glare effect. Utility Model Content

[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] Reference Figures 1 to 4 According to an embodiment of the utility model, the mirror headlight with adjustable polarization angle includes a lamp body assembly 100, a light emitting module 200, a polarizing lens 300 and a lampshade 400. The lamp body assembly 100 is provided with a receiving cavity 101, the light emitting module 200 is received in the receiving cavity 101, the polarizing lens 300 is received in the receiving cavity 101, the polarizing lens 300 is covered with the light emitting module 200, and the polarizing lens 300 is provided with a polarizing surface 310 on the side facing the light emitting module 200, and the polarizing surface 310 is used to polarize the light emitted by the light emitting module 200. 00 A light emitting surface 320 is provided on the side facing away from the light emitting module 200, and a lampshade 400 is rotatably provided on the lamp body assembly 100. The lampshade 400 is at least partially accommodated in the accommodating cavity 101, and the lampshade 400 is provided with a polarizing hole 410. The center of the polarizing hole 410 is offset from the center of the light emitting surface 320. In this way, the user can rotate the lampshade 400 according to the actual installation position of the mirror lamp to change the relative position of the polarizing hole 410 and the light emitting surface 320 to adjust the polarization direction of the mirror lamp, thereby improving the brightness of the mirror and facilitating user use.

[0032] Specifically, when the mirror lamp is working, the light emitted by the light emitting module 200 passes through the polarizing surface 310 to generate polarization inside the polarizing lens 300, and the polarized light is emitted from the light emitting surface 320, and the light emitted from the light emitting surface 320 is emitted to the outside through the polarizing hole 410. The user can rotate the lampshade 400 according to the actual installation position of the mirror lamp. Since the center of the polarizing hole 410 and the center of the light emitting surface 320 are offset, the relative position of the polarizing hole 410 and the light emitting surface 320 is changed, so that the polarization direction of the mirror lamp can be adjusted accordingly according to the specific position of the mirror. On the one hand, it can be convenient for users to use, and on the other hand, it can improve the installation flexibility of the mirror lamp.

[0033] It should be noted that, refer to Figure 5 The polarizing surface 310 may be a bevel structure or a curved structure, which is not limited here.

[0034] It should be noted that the light emitting module 200 is a light emitting component such as an LED lamp, which will not be described in detail here.

[0035] In some embodiments of the present invention, a limiting structure is provided between the lampshade 400 and the lamp body assembly 100 to limit the separation of the lampshade 400 and the lamp body assembly 100, so as to facilitate the installation of the lampshade 400.

[0036] Reference Figure 2 , Figure 6 In some embodiments of the utility model, the limiting structure includes a first spring glass bead 420 provided on the lampshade 400 and a limiting groove 103 provided on the side wall of the accommodating cavity 101. The free end of the first spring glass bead 420 is accommodated in the limiting groove 103 and can abut against the side wall of the limiting groove 103 to limit the separation of the lampshade 400 from the lamp body assembly 100, which can facilitate the installation or removal of the lampshade 400.

[0037] Specifically, the limiting groove 103 is an annular structure. When one end of the lampshade 400 enters the accommodating cavity 101, the free end of the first spring glass bead 420 abuts against the side wall of the accommodating cavity 101, so that the free end of the first spring glass bead 420 contracts. When the free end of the first spring glass bead 420 enters the limiting groove 103, the free end of the first spring glass bead 420 rebounds, so that the free end of the first spring glass bead 420 abuts against the side wall of the limiting groove 103, thereby limiting the lampshade 400 from exiting the accommodating cavity 101, which is convenient for installing the lampshade 400.

[0038] It should be noted that, under the action of external force, the free end of the first spring glass bead 420 can be contracted to facilitate the removal of the lampshade 400.

[0039] It should be pointed out that the limiting structure can also be a structure in which a limiting hole and a limiting protrusion cooperate with each other, which will not be described in detail here.
