Light source generating device

Technical Field

The utility model relates to a light source generating device that can be connected with the cell-phone can provide the red light of power emission to light source generator through the USB interface of cell-phone.

Background

The incidence of myopia of teenagers is very high in China, and according to investigation, the incidence of myopia of teenagers 15 years old in China is 78.5%. Studies have shown that increasing the production of Dopamine (DA) in the retina can have a significant impact on slowing and inhibiting the progression of the eye toward myopia.

Dopamine is a neurotransmission substance used to help cells deliver pulsatile chemicals. A large body of data can be used to support that dopamine is one of the retinal neurotransmitters involved in the signaling cascade. Dopamine receptors D1-D5 are present on the retina. Dopamine will regulate the axial growth of the eyeball to the near-sighted direction or the far-sighted direction through controlling the refractive development of eyeball structures such as the development of scleral structures through the activation and mediation of dopamine receptors.

The applicant finds that the dopamine level of retina can be improved by increasing the light intensity through long-time research on the relationship between illumination and myopia development and academic tracking in the field of ophthalmic medical treatment, and the mechanism of the dopamine-increasing mechanism is that illumination passes through a retina light-feeding passage, so that no protuberant cells on the retina generate and release dopamine. In experimental study on guinea pigs, in a comparison experiment between a highlight group and a dim group, the dopamine content of the retina of the guinea pig in the highlight group is obviously increased, the axial direction of an eyeball is shortened, and the diopter of the retina is obviously more prone to hyperopia. However, continuous strong light irradiation does not further increase the dopamine content, and the diopter changes further. This indicates that dopamine production and release are not only related to the intensity of light.

According to the research of the applicant in recent years, the mechanism of the light stimulation of the retina to inhibit the development trend of myopia is that light with specific wavelength irradiates light-feeding bipolar cells on the retina to release glutamic acid substances to stimulate amacrine-free cells to release dopamine. The released dopamine will act on dopamine D1 and D2 receptors widely distributed on the retina, and dopamine D2 and D4 receptors distributed in the Retinal Pigment Epithelium (RPE). The dopamine acting on the receptors results in flattening of corneal curvature, deeper anterior, thinner lens, and proliferation of scleral chondrocytes, which results in the axial hyperopia of the eye, inhibiting myopia. Based on the above mechanism, the applicant found that factors such as the wavelength of light applied to the retina, the power of the light, the duration of interruption of the light and the spatial area of the light applied to the retina, rather than just the intensity of the light, all combine to affect dopamine production and release and myopia inhibition of the eye.

Ophthalmic therapeutic devices designed to treat myopia and amblyopia by irradiating the retina with light have existed for many years. For example, CN107260504A, entitled apparatus for treating amblyopia and/or myopia, discloses a device for treating myopia or amblyopia by illuminating the eye with light from an eyepiece using a light source.

There is no prior art that has a miniaturized therapeutic device that can be easily carried and used. The applicant has conducted further research on the miniaturization of the light source module and the realization of functions by connecting the light source module to the portable power source terminal.
