Description

LED cosmetic mirror

Technical Field

The invention belongs to the field of cosmetic mirrors.

Technical Field

When professional makeup is carried out, the light in front of the makeup mirror is required to illuminate the face of a makeup person at all angles, and the light is uniform, which is also the basic requirement of the professional makeup mirror on the light.

The current professional cosmetic mirror is realized by a method of installing a plurality of bulbs on the periphery of the mirror or in the left, upper and right directions, as shown in figure 1. Also, in order to integrate the mirror and the light emitter, the light bulb is arranged on the 4 sides of the mirror or the left side, the upper side and the right side, as shown in fig. 2.

The advantages of the above scheme are:

1, the light is uniform. Because the bulb is full angle luminous, install in the mirror all around or left and right three direction in addition, no matter be the front direction, or the side direction, can both shine the face uniformly.

2, the design is simple and the cost is low.

However, the above solutions also have disadvantages:

1, the light source utilization rate is low. Just because the bulb is full angle luminous, but the mirror is seen when we look at makeup only need the light of front and this medial surface towards the mirror center, and the light of other directions can be in fact unnecessary, and the useless is wasted.

2, it is not beautiful. The light bulbs protruding one by one are difficult to coordinate with the mirror, and are not aesthetic.

Fig. 3 shows a planar LED lamp mirror of the prior art, which has the advantages of beauty and energy saving, but because there is no inside direction light emitting surface, the inside direction light is scattered by the front light emitting surface, and the inside direction light is weak, and cannot illuminate the face uniformly, so it cannot be used as a cosmetic mirror with high light requirement.

Disclosure of Invention

The invention provides an LED cosmetic mirror, which consists of a mirror surface and a luminous body, wherein the luminous body has light rays in the direction opposite to the mirror surface (hereinafter, the luminous body is called as a positive luminous surface) and light rays pointing to the side surface in the center direction of the mirror (hereinafter, the luminous body is called as an inner luminous surface).

As shown in fig. 4, to solve the above technical problems, the LED cosmetic mirror of the present invention comprises a mirror surface 1 and a lamp body 2 capable of emitting front light and inner side light simultaneously, wherein the light emitting surface of the lamp body 2 is located at three positions of the periphery, the left side, the upper side, and the right side, or the left side and the right side of the mirror surface 1, the light emitting surface at each position of the lamp body 2 comprises a front light emitting surface 6 and an inner light emitting surface 7, the front light emitting surface 6 emits light in the direction opposite to the mirror surface 1 when the lamp is powered on, and the inner light emitting surface 7 emits light in the direction of.

In order to make the light emitted from the cosmetic mirror substantially uniform, the light flux of the light emitted from the inner light-emitting surface 7 should be not less than 30% of the light flux of the light emitted from the front light-emitting surface 6.

Since the mirror surface 1 is generally made of a transparent glass substrate, and is plated with a reflective layer material such as silver or aluminum, and then coated with a protective finish, when the reflective layer and the protective finish are removed by a process such as sand blasting around the mirror surface 1, a light-emitting window can be made, so that the front light-emitting surface of the lamp body 2 can also adopt a light-emitting window integrated with the mirror surface 1, such as the front light-emitting surface 6 shown in fig. 13.

Because the light emitted by the inclined surface or the cambered surface can also be decomposed into the light emitted by the front light-emitting surface and the light emitted by the inner side light-emitting surface, the front light-emitting surface and the inner side light-emitting surface can also be combined into the inclined surface or the cambered surface, and can also be the mixture of the inclined surface or the cambered surface and the plane, which is called as the combined light-emitting surface in the invention. FIG. 5 shows a partial form of the front light emitting surface, the inner light emitting surface and the combined light emitting surface of the present invention.

In order to simplify the testing method, the light emitted from the light-emitting surface at the left position of the lamp body 2 (the light-emitting surface at the position inside the dashed line frame 3 in fig. 4) is used as a testing parameter; as shown in FIG. 6, the present invention refers to the light rays in the range of 0-45 degrees as the front light and the light rays in the range of 45-90 degrees as the inside light. Fig. 6 shows the luminous flux test data of the LED lamp mirror emitting light in a certain plane in the range of 0-90 degrees, which can clearly see that the luminous flux in the range of 45 degrees-90 degrees is less than 30% of that in the range of 0-45 degrees, i.e. the luminous flux of the inside light is less than 30% of that of the front light.

The smaller the mirror surface, the lower the requirement for side light, while the larger the mirror surface, the greater the distance of the peripheral light emitting surface from the makeup person, and too far distance is not good for uniformity of light, so the size of the mirror surface of the present invention is generally in the range of 15cm to 120cm square.
