In practical applications, the light beam transmission module may be configured to transmit the light beam of the light emitting module in the skin surface light treatment device, and in particular, the light beam transmission module may be a silicate nonmetallic material, and an outer surface of the light beam transmission module may be used to abut the skin.
In one possible embodiment, the device further comprises an optical shaping module for changing the path of the light beam of the light emitting module to irradiate the light beam towards the target area.
Fig. 7 is a schematic structural view of a skin surface light treatment device provided with a plurality of reflective cups 3 according to an embodiment of the present invention. In one possible embodiment, the optical shaping module may comprise a reflector cup 3, at least two light emitting units being arranged inside the reflector cup; or, at least two light emitting units are respectively arranged at the inner sides of the plurality of light reflecting cups 3, in practical application, each light emitting unit is respectively arranged at the inner sides of the single light reflecting cup 3, and the light emitted by each light emitting unit can be emitted after being shaped by the high-reflection light reflecting cup 3. By providing a single highly reflective reflector cup 3 for each light emitting unit individually, the target light emitting unit achieves an optimal shaping effect of the light beam of the target light emitting unit through its reflector cup 3 when illuminating the target area of the target object.
Fig. 8 is a schematic structural view of a skin surface light treatment device according to an embodiment of the present invention, in which at least two light guide plates 4 are disposed. In a possible embodiment, the optical shaping module may comprise one or at least two light guide plates 4, the light guide plates 4 being arranged between the plane of the light emitting module 1 and the plane of the target area of the target object 2. In practical application, a light guide plate is integrally arranged on the light emitting surface of the light emitting module; alternatively, a single light guide plate 4 may be provided for each light emitting unit 11, and the light emitted from each light emitting unit 11 may be shaped by the light guide plate 4 and then emitted. By providing a single light guide plate 4 for each light emitting unit 11, the target light emitting unit achieves an optimal shaping effect of the light beam of the target light emitting unit through its light guide plate 4 when illuminating the target area of the target object. The material of the light guide plate may be a material having a high refractive index and a low absorbance, such as glass or plastic.
TABLE 1
The difference between the light emitting area of the light emitting unit and the cross-sectional area of the light guide plate has an effect on the optical power density of the light emitted from the light guide plate. Table 1 shows the maximum energy density and the maximum dose with the dimensions of the light guide plateA variable data table. The specific parameters are that each chip is 0.88W, the chip adopts LEDs, and the chip size is 1.1 x 1.1mm 2 The light emitting units are distributed in four strings and three parallel, the distance between the light emitting surface and the incidence surface of the light guide plate is set to be 0.3mm, the distance between the target object and the emergent surface of the light guide plate is set to be 0.05mm, the size of the light guide plate is set to be 2.5mm x 10mm x 5mm,2.5mm x 11mm x 5mm,2.5mm x 12mm x 5mm,3.0mm x 10mm x 5mm, and 3.5mm x 10mm x 5mm respectively. When the irradiation time period of the single light emitting unit is 0.2 seconds, it can be seen that the optical power density and the irradiation dose decrease as the size of the irradiated surface and the light guide plate become larger.
It can be seen that the area of the cross section of the light guide plate (the cross section parallel to the light emitting units) is adapted to the area of the light emitting units, that is, each light guide plate is matched with each light emitting unit, in practical application, the cross section area of the light guide plate may be approximately equal to the cross section area of the light emitting units, or may be slightly larger than the cross section area of the light guide plate, so as to ensure the maximization of the illumination intensity emitted from the light guide plate, and it can be understood that the too large or too small cross section area of the light guide plate relative to the light emitting units can cause the loss of the light emitted from the light emitting units, thereby reducing the illumination intensity of the emitted light.
TABLE 2
Table 2 is a data table of the change of the highest energy density and the highest dose with the distance between the light emitting surface and the incident surface of the light guide plate, the specific light source setting is the same as the above condition, the light guide plate size is 2.5mm x 10mm x 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,0.9mm, the irradiation duration of a single light emitting unit is 0.2 seconds, and it can be seen from the above table that the light power density and the irradiation dose decrease with the increase of the distance between the light emitting surface and the incident surface of the light guide plate.
TABLE 3 Table 3
Table 3 is a data table of the change 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 light guide plate dimensions are the same as the above conditions, the distance between the light emitting surface and the entrance surface of the light guide plate is 0.3mm, the distances between the target object and the exit surface of the light guide plate are respectively 0.1mm,0.3mm,0.5mm,0.7mm,0.9mm, and the irradiation time of a single light emitting unit is 0.2 seconds, so it can be seen from the above table that the light power density and the irradiation dose decrease with the increase of the distance between the irradiated surface and the exit surface of the light guide block.
From the above results, it can be seen that the light guide plate is preferably mounted so as to be as closely attached to the light emitting surface of the light emitting unit as possible. Because the irradiation light power density of a single light-emitting unit in single lighting is lower than that of a plurality of light-emitting units in simultaneous lighting, the influence of the space 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, so that the irradiation light power density of the single light-emitting unit in single lighting is ensured to meet the actual application requirement. In practical application, the electrode is connected by using a vertical chip lead wire, and the distance between the light guide plate and the light emitting surface needs to be kept to be the height of the lead wire, and the minimum height is about 0.3mm because the lead wire has radian; in another scheme, when the flip chip is adopted, the electrode is arranged below the chip, jumper connection is not needed, and the light guide plate can be attached to the light emitting surface as much as possible, but seamless attachment cannot be achieved due to the difference of the thicknesses of the chips. According to the current chip mounting mode of the light emitting module, as the brightness of the flip chip is still different from that of the vertical chip, the current preferred scheme can be to select the vertical chip to lead the gold wire to connect the electrode and leave the height for the jumper wire, i.e. the distance between the light emitting surface of the light emitting module and the incident surface of the light guide plate can be 0.3mm. 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, along with the gradual development of the chip process, 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 preferable scheme to increase the light power density of the light emitted by the light guide plate, 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.

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 both 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 provided on the surface of the light guide plate in the form of a coating film, or may be attached to the surface of the light guide plate in the form of an adhesive, which is not limited herein.
