Abstract

The utility model provides a light mask front screen with a light uniformizing effect and a light mask. The light mask front screen comprises a skin attaching face used for being attached to the face skin of a human body and a low-beam face covering a light source. A first refraction structure used for diverging light of the light source is designed on the low-beam face. According to the utility model, on the premise that the basic structure of the skin-attaching type light mask is not changed, the transparent front screen of the light mask is transformed, so that the light mask has a certain optical structure and optical effect. Under the new transparent front screen structure with the light uniformizing effect, the light can be irradiated on the face area more uniformly. Uniform irradiation can greatly improve the use feeling of a user, the phototherapy effect is enhanced, and the appearance of the product is more attractive.

Description

Technical Field

[0001] The utility model relates to the technical field of optical beauty, in particular to a light mask front screen and a light mask with a uniform light effect. Background Art

[0002] Light mask products achieve a series of skin care effects by irradiating facial skin with light. For LED light masks, a layer of transparent medium (usually silicone) is required in front of the LED light source to contact the skin. The current layer of silicone is a flat structure, which has no guiding and distribution effect on the light. Therefore, the irradiance received by the skin may be strongest directly under the LED and weakest in the middle of the two LEDs. This uneven light intensity will prevent phototherapy beauty from achieving the best effect. In order to improve the overall product quality and phototherapy effect, it is imperative to design a product with better light uniformity.

[0003] In order to create a uniform illumination effect, a typical idea is to use a light guide plate to even out the light, such as the patent application document with patent number "CN106390302A". This technical solution diffuses the light of the LED light strip to the entire face through a light guide film. However, this technical solution concentrates all light sources on one light strip, greatly increasing the heat at the light source, reducing the user experience and the difficulty of heat dissipation in engineering, and there is a large waste of energy, which is not an ideal solution.

[0004] Therefore, the utility model proposes a new glossy film front screen and a glossy film with a light uniforming effect to solve the above problems. Summary of the invention

[0005] In order to solve the above technical problems, the utility model discloses a glossy film front screen and a glossy film with a uniform light effect. The technical solution of the utility model is implemented as follows:

[0006] A light mask front screen with a uniform light effect, comprising a skin-contacting surface for fitting to human facial skin and a low-light surface covering the light source;

[0007] The low beam surface is designed with a first refractive structure for diverging the light from the light source.

[0008] Preferably, the first refractive structure is arc-shaped or folded-line-shaped.

[0009] Preferably, two adjacent first refractive structures are axisymmetric.

[0010] Preferably, the skin-contacting surface is provided with a second refractive structure;

[0011] The second refractive structure includes a light diverging portion and a light converging portion;

[0012] The light gathering portion is arranged on both sides of the light diverging portion.

[0013] Preferably, two sides of the light diverging portion are recessed inwards, and the light gathering portion is in a broken line shape or an arc shape.

[0014] A glossy mask with a light-homogenizing effect uses the glossy mask front screen with a light-homogenizing effect.

[0015] The utility model, without changing the basic structure of the skin-fitting light mask, transforms the transparent front screen of the light mask to give it a certain optical structure and optical effect. Under the new transparent front screen structure with uniform light effect, the light will be irradiated more evenly on the facial area. The uniform irradiation can greatly improve the user's experience, enhance the light therapy effect, and make the product more beautiful. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following will be combined with the embodiments of the utility model and its drawings to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example 1

[0029] In a specific embodiment 1, a light mask front screen with a uniform light effect includes a skin-contacting surface 2 for fitting the human facial skin and a low-light surface 3 covering the light source 1; the low-light surface 3 is designed with a first refractive structure 3-1 for diverging the light from the light source 1.

[0030] like Figure 2 As shown, the first refractive structure 3-1 is arc-shaped.

[0031] In this embodiment, the silicone film (glossy film front screen) directly in front of the light source 1 is designed to be arched (ie, the arc-shaped first refractive structure 3 - 1 ).

[0032] like Figure 1 As shown, in the prior art, the light emitted by the light source 1 will move along its initial direction after passing through the planar transparent medium (glossy film front screen). Figure 1 By comparison, we can find that Figure 2 In the embodiment, the light emitted by light source 1 will have a larger divergence angle, thereby covering a larger range, and therefore, the uniformity of light is better.

[0033] This embodiment does not need to change the basic structure of the skin-fitting light mask, but only transforms the transparent front screen of the light mask to give it a certain optical structure and optical effect. Under the new transparent front screen structure with uniform light effect, the light will be more evenly irradiated on the facial area. Uniform irradiation can greatly improve the user experience, enhance the light therapy effect, and make the product more beautiful.

[0034] In addition, it should be noted that when the distance between the light sources 1 in the optical film is large enough, the first refractive structures 3-1 corresponding to each light source 1 are Figure 1 When the light sources 1 in the optical film are too dense, the corresponding first refractive structures 3-1 will be deformed appropriately, for example Figure 3 Although the adjacent first refractive structures 3-1 are still axisymmetric, the individual first refractive structures 3-1 are Figure 1 Some arcs will be missing. In practical applications, each first refractive structure 3-1 can be set to be independent or the vertical projections of the first refractive structures 3-1 can be partially overlapped according to the light source density of the glossy film.

[0035] Example 2

[0036] In a specific embodiment 2, a light mask front screen with a uniform light effect includes a skin-contacting surface 2 for fitting the human facial skin and a low-light surface 3 covering the light source 1; the low-light surface 3 is designed with a first refractive structure 3-1 for diverging the light from the light source 1.

[0037] like Figure 4 As shown, the first refractive structure 3-1 is in the shape of a broken line.

[0038] Different from the embodiment 1, the first refractive structure 3-1 is designed to be a broken line on the near light surface 3 in the embodiment 2. The light divergence angle of the light source 1 under this design is also much larger than that of the prior art ( Figure 1 shown).

[0039] Example 3

[0040] In a preferred embodiment 3, a light mask front screen with a uniform light effect includes a skin-contacting surface 2 for fitting the human facial skin and a low-light surface 3 covering the light source 1; the low-light surface 3 is designed with a first refractive structure 3-1 for diverging the light from the light source 1.

[0041] like Figure 5 As shown, the first refractive structure 3-1 is arc-shaped. The skin-contacting surface 2 is provided with a second refractive structure; the second refractive structure includes a light diverging portion 2-2 and a light gathering portion 2-1; the light gathering portion 2-1 is provided on both sides of the light diverging portion 2-2. Both sides of the light diverging portion 2-2 are concave inwards, and the light gathering portion 2-1 is arc-shaped.

[0042] This embodiment is an optimization of embodiment 1. Compared with embodiment 1, this embodiment sets a second refractive structure on the skin-contacting surface 2 of the front screen of the glossy mask. At the large light angle of the light source 1, the surface is thickened, and the refraction direction of the light will no longer increase, so as to avoid becoming grazing light and leaking from the gap of the glossy mask. The light diverging part 2-2 in the middle further improves the uniformity of light.

[0043] Example 4

[0044] In a specific embodiment, a glossy film with a uniform light effect uses any glossy film front screen as described in any one of embodiments 1-3.

[0045] Since the glossy front screen of Examples 1-3 does not change the basic structure of the glossy film, most glossy films on the market can use the glossy front screen of Examples 1-3. The glossy film referred to in this embodiment is any glossy film on the market that can be adapted to the glossy front screen of Examples 1-3.

[0046] The improvement focus of the utility model is to change the details of the existing smooth film front screen. Its overall outline is the same as that of the traditional smooth film front screen in vertical projection (that is, almost unchanged when observed with the naked eye). Therefore, the overall structural diagram of the smooth film front screen is not attached in each embodiment. The structure of the traditional smooth film front screen is the existing technology in this field, that is, the shape is the same as that of the smooth film product.

[0047] It should be pointed out that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
