Description

Skin surface treatment device based on light energy

Technical Field

The utility model relates to the technical field of photoelectricity, in particular to a skin surface treatment device based on light energy.

Background

The light can be used for beautifying and treating surface tissues, such as skin ablation, skin tendering, acne removing, freckle removing, hair removal, wound healing promotion, photocoagulation, psoriasis treatment, diabetic foot treatment and other medical and cosmetic fields. In performing the relevant medical and aesthetic procedures, it is necessary to apply high-energy light to the target tissue region using a light source.

The existing light irradiation equipment mainly adopts intense pulse light and laser as light sources, and the intense pulse light is wide-spectrum visible light with special wavelength and has softer photo-thermal effect. The photochemical action generated after the intense pulse light acts on the skin enables the collagen fiber and the elastic fiber in the dermis to generate the chemical change of the molecular structure, and the original elasticity is recovered. In addition, the generated photothermal effect can enhance the function of blood vessels and improve circulation, thereby achieving the treatment effects of eliminating wrinkles and reducing pores; since the content of pigment clusters in the lesion tissue is much greater than that in normal skin tissue, the temperature rise after absorption of light is also higher than that of the skin. The temperature difference between the two parts is utilized to close the pathological blood vessel and break and decompose the pigment without damaging normal tissues. The laser hair follicle-destroying device has the advantages of being high in speed, good in effect, high in safety, free of side effect, free of pain, capable of shrinking pores, moistening skin and the like.

However, when intense pulsed light is used as a light source, in order to achieve the required energy density, a larger light source volume is usually set, which causes a larger spectral width and light emitting area, a low unit energy density, and a large-area light emitting manner to cause pain to a user, the residual heat can burn and necrose cells in a non-target tissue area, and meanwhile, the requirement for power of equipment is high, the cost is high, and the heat is high, and there is a problem of heat dissipation.

TABLE 1

Wherein, the difference between the light-emitting area of the light-emitting unit and the cross-sectional area of the light guide plate has an influence on the optical power density of the light emitted by the light guide plate. Table 1 is a table of data for the highest energy density and highest dose as a function of light guide plate size. The specific parameters are that each chip is 0.88W, the chip adopts an LED, and the size of the chip is 1.1 x 1.1mm²The light-emitting units are distributed in four strings and three parallel and are provided with light-emitting surfacesThe distance between the target object and the light guide plate emergent surface is 0.05mm, and the sizes of the light guide plate are respectively 2.5mm 10mm 5mm, 2.5mm 11mm 5mm, 2.5mm 12mm 5mm, 3.0mm 10mm 5mm and 3.5mm 10mm 5 mm. When the illumination time of a single light emitting unit is 0.2 seconds, it can be seen that the optical power density and the illumination dose decrease as the size of the illuminated surface and the light guide plate becomes larger.

It can be seen that the area size of the cross section of the light guide plate (cross section parallel to the light emitting cells) is adapted to the area of the light emitting cells as a preferred solution, i.e. each light guide plate is matched to each light emitting cell. In practical applications, the cross-sectional area of the light guide plate may be approximately equal to the cross-sectional area of the light emitting unit, or slightly larger than the cross-sectional area of the light guide plate, so as to ensure the maximization of the intensity of the light emitted from the light guide plate. It is understood that the cross-sectional area of the light guide plate is too large or too small relative to the light emitting unit, which results in loss of light emitted from the light emitting unit, thereby reducing the illumination intensity of the emitted light.

TABLE 2

Table 2 shows the data table of the variation of the maximum energy density and the maximum dose with the distance between the light emitting surface and the incident surface of the light guide plate, the specific light source settings are the same as the above conditions, the size of the light guide plate is 2.5mm by 10mm by 5mm, the distance between the irradiated surface and the emergent surface of the light guide plate is 0.05mm, the light emitting surface of the light emitting module and the incident surface of the light guide plate are respectively set to be 0.1mm, 0.3mm, 0.5mm, 0.7mm and 0.9mm, the irradiation time of a single light emitting unit is 0.2 seconds, and as can be seen from the above table, the optical power density and the irradiation dose are reduced with the increase of the distance between the light emitting surface and the incident surface of the light guide plate.

TABLE 3

Table 3 is a data table of the variation of the highest energy density and the highest dose with the distance between the exit surface of the light guide plate and the target object, the specific light source setting and the size of the light guide plate are the same as the above conditions, the distance between the light emitting surface and the incident surface of the light guide plate is 0.3mm, the distance between the target object and the exit surface of the light guide plate is respectively set to be 0.1mm, 0.3mm, 0.5mm, 0.7mm and 0.9mm, and the irradiation duration of a single light emitting unit is 0.2 second.

As can be seen from the above results, the light guide plate is preferably attached to the light emitting surface of the light emitting unit in close contact therewith as much as possible. Because the irradiation light power density of a single light-emitting unit during single lighting is lower than the irradiation light power density of a plurality of light-emitting units during simultaneous lighting, the influence of the distance between the light-emitting surface and the surface of the target object on the light power density is reduced by adopting a light guide mode, and the irradiation light power density of the single light-emitting unit during single lighting meets the requirement of practical application. In practical application, the vertical chip gold leading wire is used for connecting the electrodes, and the wire jumper has radian, so that the distance between the light guide plate and the light emitting surface needs to be reserved for the height of the wire jumper, and the minimum height is about 0.3 mm; in another scheme, when a flip chip is used, the electrodes are arranged below the chip, and the light guide plate can be attached to the light-emitting surface as much as possible without jumper connection. According to the chip mounting method of the light emitting module adopted at present, because the brightness of the flip chip has a certain difference with the brightness of the vertical chip, the current preferred scheme can be that a gold wire of the vertical chip is selected to connect the electrodes and a height is reserved for the jumper wire, namely, the distance between the light emitting surface of the light emitting module and the incident surface of the light guide plate can be 0.3 mm. The distance between the light-emitting surface of the light-emitting module and the incident surface of the light guide plate is affected by the light-emitting module process, and as the chip process gradually develops, under the condition that the chip process meets the requirements, a light-emitting module structure capable of minimizing the distance between the light-emitting surface of the light-emitting module and the incident surface of the light guide plate can be selected as a preferred scheme, so that the optical power density of the emergent light of the light guide plate is increased, and the specific installation mode of the light guide plate and the distance between the light-emitting surface of the light-emitting module and the incident surface of the light guide plate are not limited in the disclosure.

The specific installation method of the light guide plate may be the following two installation methods. Fig. 9 and fig. 10 are schematic views of an installation structure of a skin surface light treatment device according to an embodiment of the present invention and an exploded view thereof, respectively. As shown in fig. 9 and 10, a specific mounting manner may be that the light guide plate holder 6 is fixed on the substrate 7, and the plurality of light guide plates 4 are sequentially placed on the bosses in the light guide plate holder 6.

As shown in fig. 11 and 12, a specific mounting method may be to fix the frame 8 on the substrate 7 by using a curing adhesive and then fix the plurality of light guide plates 4 on the frame 8 in sequence when the substrate 7 is packaged.

In one possible embodiment, the optical shaping module may also include at least one light guide plate and at least one light reflecting cup. It is understood that the optical shaping for each light emitting unit may be performed in a form of a combination of a reflective cup and a light guide plate, for example, when the light emitting module includes 5 light emitting units, 2 of the light emitting units may be optically shaped by being provided with 2 reflective cups, and another 3 of the light emitting units may be optically shaped by being provided with 3 light guide plates, and the relative positions and numbers of the reflective cups and the light guide plates in practical application may be set according to practical situations, which is not limited herein.

It can be understood that, when the optical shaping module includes a plurality of light guide plates, the incident surface and the exit surface of each light guide plate are provided with an antireflection film, and the side surface of each light guide plate is provided with a reflection film. Specifically, the antireflection film and the reflection film may be disposed on the surface of the light guide plate in a form of a plated film, or may be attached to the surface of the light guide plate in a form of a paste, which is not limited herein.

In one possible embodiment, one side of the optical shaping module is provided with a protective layer, the protective layer is arranged between the optical shaping module and the target object, the area of the protective layer can be larger than or equal to the area of the light emitting module, and the protective layer is used for protecting the integral structure of the light emitting module and the optical shaping module inside the protective layer. The material of the protective layer includes, but is not limited to, a material having high transmittance such as glass, plastic, or resin.

In practical applications, in the lighting sequence of the lighting units controlled by the lighting sequence signal, any two adjacent lighting units may be adjacent, and specifically, the lighting units may be lighted in a sequential lighting manner, for example, taking the structure of the lighting module 5 × 5 in fig. 8 as an example, the lighting sequence of the lighting units may be 1,2,3,4,5,6,7, …; or 1,6,11,16,21,2,7,12,17, 22; 1,2,3,4,5,10,9,8,7, 6; 1,6,11,16,21,22,17,12,7,2. In another possible embodiment, in the lighting sequence of the lighting units controlled by the lighting sequence signal, any two adjacent lighting units may not be adjacent, for example: the lighting order of the light emitting units may be: 1 → 3 → 5 → 6 → 8 → 10 → 11 → 13 → 15 → 16 → 18 → 20 → 21 → 23 → 25 → 2 → 4 → 7 → 9 → 12 → 14 → 17 → 19 → 22 → 24; alternatively, the light emitting units may be composed of light emitting elements in each horizontal row, each square corresponding to fig. 8 is a single light emitting element, for example, the light emitting units may be composed of 1-5,6-10,11-15,16-20 and 21-25 in fig. 8, respectively; the lighting sequence of the light-emitting units can also be 1-5 → 11-15 → 21-25 → 6-10 → 16-20, namely, a row of light-emitting elements is arranged between any two adjacent light-emitting units; the lighting sequence of the light emitting units may also be that the next light emitting unit in any two adjacent light emitting units that are lit is not located around the last light emitting unit that is lit (i.e. may not be 8 light emitting units around the light emitting unit), for example, the lighting sequence of the light emitting units is 1,12,22,19,10,8,18,16,6,3,5,15,25,23,21,7,14,24,13,4,2,11,9,17,20, and by adopting the jump lighting mode, the temperature difference between the light emitting module surface lighting unit and the unlit area can be made larger, so as to achieve better heat dissipation effect.
