Title:
PROGRAMMABLE GRAPHIC PROJECTION LIGHT SOURCE SYSTEM FOR OPHTHALMOLOGY
Document Type and Number:
WIPO Patent Application WO/2023/103245
Kind Code:
A1
Abstract:
The present invention relates to a programmable graphic projection light source system for ophthalmology, comprising a light source, a flexible screen, a reflective coating, and a light shielding plate. The light shielding plate is located between the light source and pupils; the light source emits light in an opposite direction facing a refraction plate; the flexible screen is located on the other side, opposite to the light shielding plate, of the light source; the reflective coating is located on the other side, opposite to the light source, of the flexible screen and comprises a spherical face portion located in the middle and a plane portion surrounding the spherical face portion; after the light emitted by the light source is reflected by the spherical face portion, part of a projected flexible screen pattern is shielded by the light shielding plate, and the other part is orthogonally emitted to the periphery of the pupils; and after the light emitted by the light source is reflected by the plane portion, part of a projected flexible screen pattern is obliquely emitted to the pupils. By using the solution, the present invention provides a programmable graphic projection light source system for ophthalmology, capable of preventing ultraviolet rays from orthogonally irradiating to the fundi of the eyes, so as to protect the eyes of patients.
