Description

An LED makeup mirror

Technical field

The invention belongs to the field of makeup mirrors.

Background technique

For professional makeup, the light in front of the makeup mirror needs to illuminate the makeup person's face from all angles, and the light is even. This is also the basic requirement of professional makeup mirrors for light.

The current professional makeup mirror is realized by installing multiple light bulbs around the mirror or in three directions on the left, top, and right, as shown in Figure 1. In order to integrate the mirror and the luminous body, it is also realized by installing the bulbs on the 4 sides of the mirror or the three parts on the left, upper and right sides of the mirror, as shown in Figure 2.

The advantages of the above scheme are:

1. Even light. Because the bulb emits light from all angles, and it is installed around the mirror or in the three directions of left, upper and right, whether it is the front direction or the side direction, it can illuminate the face evenly.

2. Simple design and low cost.

But the above scheme also has disadvantages:

1. The light source utilization rate is relatively low. It is precisely because the light bulb emits light from all angles, and when we look at the mirror when we make up, we only need light from the front and the inner side of the center of the mirror. Light from other directions is actually unnecessary, and it is wasted.

2. Not beautiful. The protruding bulbs are difficult to coordinate with the mirror and have no aesthetic feeling.

Figure 3 is a prior art flat light emitting LED light mirror, which has the advantages of beauty and energy saving. However, since there is no light emitting surface in the inner direction, the light in the inner direction depends on the scattering of the front light emitting surface, and the light in the inner direction is very weak and cannot be uniformly illuminated. It brightens the face, so it cannot be used as a makeup mirror that requires high light.

Summary of the invention

technical problem

The solution to the problem

Technical solutions

The technical problem to be solved by the present invention is to provide an LED makeup mirror, which is composed of a mirror surface and a luminous body. The luminous body has both the light in the direction facing the mirror surface (hereinafter referred to as the "front light-emitting surface") and the direction The light from the side of the center of the mirror (hereafter referred to as the "inner light-emitting surface"), the LED makeup mirror designed in this way not only retains the advantages of the existing makeup mirror with uniform light, but also solves the shortcomings of low light efficiency and unsightly .

As shown in Figure 4, in order to solve the above technical problems, the LED makeup mirror of the present invention is composed of a mirror 1 and a lamp body 2 that can simultaneously emit frontal light and inner side light. The feature is that the light-emitting surface of the lamp body 2 is located on the mirror surface 1. Around or at three positions on the left, top, and right or two positions on the left and right, the light-emitting surface of each of the above positions of the lamp body 2 contains a positive light-emitting surface 6 and an inner light-emitting surface 7, and the positive light-emitting surface 6 faces the mirror 1 when the power is on Light is emitted in the direction, and the inner light-emitting surface 7 emits light toward the side of the center of the mirror 1.

In order to make the light emitted by the vanity mirror basically uniform, the luminous flux of the light emitted by the inner light-emitting surface 7 should not be less than 30% of the luminous flux of the light emitted by the front light-emitting surface 6.

Since the mirror 1 is generally made of a transparent glass substrate, plated with reflective layer materials such as silver or aluminum, and then coated with a protective finish, when the mirror 1 is surrounded by sandblasting and other processes to remove the reflective layer and protective finish, it can be The light-emitting window is made, so the front light-emitting surface of the lamp body 2 can also be a light-emitting window integrated with the mirror surface 1, such as the front light-emitting surface 6 shown in FIG.

Since the light emitted by the inclined or curved surface can also be decomposed into the light emitted by the front light-emitting surface and the light emitted by the inner light-emitting surface, the front light-emitting surface and the inner light-emitting surface can also be combined into a slope or arc, or a slope or arc and The mixing of planes is called a combined light-emitting surface in the present 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 test method, the light emitted from the light-emitting surface at the left side of the lamp body 2 (the light-emitting surface in the dashed frame 3 in Figure 4) is used as the test parameter; as shown in Figure 6, the present invention will be in the range of 0-45 degrees The light inside is collectively referred to as frontal light, and the light within the range of 45 degrees to 90 degrees is collectively referred to as inner side light. Figure 6 shows the luminous flux test data of a certain plane emitting LED light mirror in the range of 0-90 degrees. The data can clearly show that the luminous flux in the range of 45 degrees to 90 degrees is less than the luminous flux in the range of 0-45 degrees. 30%, that is, the luminous flux of the inner side light is less than 30% of the front light.

The smaller the mirror surface, the lower the requirement for side light, and the larger the mirror surface, the greater the distance between the surrounding light-emitting surface and the makeup artist, and the too far distance is not conducive to the uniformity of light. Therefore, the size of the mirror surface of the present invention is generally 15cm To within 120cm square.
