Problems solved by technology

[0002] Lamps are divided into two types, one is for lighting, such as fluorescent lamps and ceiling lamps, and the other is for rendering indoor atmosphere, such as wall washers and various light strips; in the prior art, many indoor spaces such as large The center of the office building, the basement and other areas cannot see the blue sky, and can only be illuminated by lights; the blue sky lights in the prior art are generally composed of a light source and a pattern plate with blue sky and white clouds drawn on it, and the pattern plate is lit by the light source to form an outdoor blue sky. Light environment, the outdoor light environment simulated by this type of blue sky light is: the light emitting surface is pure blue or the effect of blue sky and white clouds, and the outgoing light is also blue, which cannot truly show the matching effect of blue sky and sunlight
[0003] Chinese invention patent CN111623286A discloses a lighting fixture, which solves the problem that the lighting fixtures in the prior art cannot simulate the illumination effect of the blue sky in the natural state by setting a Rayleigh scattering plate (that is, the clear sky plate described in this application) Problem; however, the light projected onto the wall is in a fixed position and cannot be moved, so it lacks a real dynamic sunlight effect; in addition, the Chinese invention patent CN111623286A discloses a lighting fixture whose light-emitting component structure is complex and needs further improvement

Abstract

The invention relates to the technical field of illuminating lamps, and particularly discloses a light-emitting device capable of adjusting a light irradiation position. The light-emitting device capable of adjusting the light irradiation position comprises: a lamp cavity; a lamp panel base, wherein an LED lamp strip is arranged on the upward surface of the lamp panel base; an optical lens, wherein the optical lens is fixed above the lamp panel base in parallel, so that the LED lamp strip is positioned between the lamp panel base and the optical lens; a lamp panel base fixing assembly, wherein the lamp panel seat fixing assembly is arranged at the bottom of the lamp cavity and is rotatably connected with the lamp panel base, so that the lamp panel base rotates relative to the bottom surface of the lamp cavity; and a clear sky plate, wherein the clear sky plate is arranged at the top of the lamp cavity. According to the light-emitting device capable of adjusting the light irradiation position, the projection angle of the light projected by the light-emitting device can be shifted according to different time periods, so that the dynamic irradiation angle of real sunlight and the light intensity are simulated, and the scene effects that the sun rises on the east, falls on the west, and is in the morning and dusk are formed.
