Problems solved by technology

[0004] However, in order to achieve the above effects, most of the industry currently uses laser or pulsed light, so the energy or intensity of the two kinds of light is sufficient to achieve the above effects, but it is easy to cause cell damage
Recently, general light sources or light-emitting diode light sources have been actively developed to replace the above-mentioned high-intensity light sources. However, due to the weak energy of light-emitting diode light sources, it is urgent to find an appropriate illuminance to achieve the effect. Otherwise, the curative effect will not be exerted if the light illuminance is too low; When the light illumination is too high, in addition to causing cell damage, it will also increase the volume of the device, making it impossible to develop a small and lightweight portable phototherapy device

Embodiment 1

[0039] refer to Figure 1 to Figure 3 ,in figure 1 It is a structural schematic diagram of the photostimulation device of the present invention, figure 2 It is a side view of the photostimulation device of the present invention, image 3 It is a system block diagram of the photostimulation device of the present invention.

[0040] Such as Figure 1 to Figure 3 As shown, the photostimulation device of the present invention includes: a casing 10 , a light-diffusing sheet 12 , a light-transmitting sheet 13 , a first light source module 40 , a second light source module 50 and a control module 30 .

[0041] The casing 10 forms an accommodating space for accommodating various modules. In addition, the casing 10 has a top surface 11 and a side edge 12 , the top surface 11 has a light outlet 111 , and the side edge 12 has a light hole 121 .

[0042] The light outlet 111 on the top surface 11 is covered by the diffuser 12 ; the light outlet 121 on the side edge 12 is covered by ...

Embodiment 2

[0048] Human fibroblasts were irradiated with the photostimulation device of Example 1 above, and its effect on cell viability was studied. In this embodiment, the light emitting diode used in the light source module of the light stimulation device emits red light with an illumination of 9,250 lux.

[0049] First, add DMEM cell culture medium containing human fibroblasts to a 48-well culture dish, and the number of cells inoculated is 2×10 4 Each well, the total volume of culture medium (including cells) in each well of 48 wells is 0.5ml, placed in CO 2 Incubator for 24 hours. After that, take out all the culture medium, add 0.5ml of PBS buffer, and use the red light stimulation device (Lux 9,250) of Example 1 to irradiate for 5, 10, 15, 30, 45, 60, 90 minutes, then take out all the culture medium in the well. Add 0.5 ml of culture medium to the PBS buffer and incubate for another 24 hours.

[0050] Then, replace with 0.5ml of new medium and add 0.125ml of MTT reagent, put ...

Embodiment 3

[0053] From the results of Example 2 above, it can be seen that after 5 minutes to 30 minutes of irradiation with a red light-emitting diode with an illumination of 9,250 lux, the survival rate of human fibroblasts can be improved, and all irradiation times are in line with the safety of the course of treatment. In this embodiment, the number of times of illumination was further changed from one to two, and the illumination of the red light-emitting diode was further reduced to 7,800 lux, and then the cell viability test was carried out.

[0054] First, add DMEM cell culture medium containing human fibroblasts to a 48-well culture dish, and the number of cells inoculated is 2×10 4 Each well, the total volume of culture medium (including cells) in each well of 48 wells is 0.5ml, placed in CO2 Incubator for 24 hours. Afterwards, take out all the culture medium, add 0.5 ml of PBS buffer, and use the red light stimulation device (Lux 7,800) of Example 1 to irradiate for 5, 10, 15,...

Abstract

The invention relates to a photostimulation method and a photostimulation device. The photostimulation method comprises the following steps: providing a light-emitting diode light source which is one of clusters formed by a yellow light-emitting diode, a red light-emitting diode and a blue light-emitting diode, and irradiating the light source of the light-emitting diode to a main body to promote collagen protein synthesis, or to restrain growth of bacteria or to restrain melanogenesis, wherein the intensity of illumination of the red light-emitting diode is 1,000 lux to 3,500 lux, the intensity of illumination of the red light-emitting diode is 6,000 lux to 9,500 lux, and the intensity of illumination of the blue light-emitting diode is 3,000 lux to 7,000 lux.

Description

technical field [0001] The invention relates to a light stimulation method and a light stimulation device, in particular to a light stimulation method and a light stimulation device which can promote collagen synthesis, strengthen inhibition of bacterial growth or inhibit melanin formation. Background technique [0002] In dermatological diagnosis, drugs are often used to treat patients with skin diseases, such as acne, but for a long time, the results of drug treatment are often accompanied by side effects. Long-term use will cause a burden on the body’s metabolism, and the treatment effect is not ideal. There is a risk of recurrence, and it cannot effectively improve the patient's skin problems. [0003] In recent years, the medical beauty industry has become increasingly prosperous. Studies have pointed out that blue light with a wavelength between 400nm and 475nm can be used for acne treatment, because blue light will interact with acne bacteria (Propionibacterium acnes)...
