Problems solved by technology

The above-mentioned patents all use the light beam to directly pass through the rotating interference disk to produce a dynamic nebula effect, which will easily cause the part with strong light to be too bright and dazzling, which is not conducive to watching the dynamic changes of the nebula for a long time

Embodiment 1

[0048] Such as figure 1 As shown, the star projection lamp provided in this embodiment includes at least one beam generator, an interference sheet 2 for producing a nebula effect, a reflector 3 and at least one first lens 41, and the beam generator is placed on the interference sheet 2 On one side of the interference plate 2, the beam generator generates a beam along the incident light path and irradiates one side of the interference plate 2. The mirror 3 is placed on the other side of the interference plate 2. After the interference plate 2 is irradiated by the beam, a part of the light in the beam encounters After reaching one side of the interference plate 2, it is directly reflected, and the other part of the light passes through the interference plate 2 for the first time and then reaches the reflector 3, and after being reflected by the reflector 3, the light beam passes through the interference plate 2 for the second time and is emitted. A part of the light passes throu...

Embodiment 2

[0054] Such as figure 2 As shown, the star projection lamp provided in this embodiment includes at least one beam generator, an interference sheet 2 for producing a nebula effect, a reflector 3 and at least one first lens 41, and the beam generator is placed on the interference sheet 2 On one side of the interference plate 2, the beam generator generates a beam along the incident light path and illuminates one side of the interference plate 2, the mirror 3 is placed on the other side of the interference plate 2, and at least one first lens 41 is located on the outgoing light path of the interference plate 2 , the light beam emitted from one side of the interference plate 2 passes through at least one first lens 41 to form a moving nebula hierarchical projection. The star projection lamp provided in this embodiment also includes a connecting shaft 10 and a first motor 61. The first motor 61 is controlled by the motor control unit 7, and the motor control unit 7 controls the sp...

Embodiment 3

[0056] Such as image 3 As shown, the starry sky projection lamp provided in this embodiment includes at least one beam generator, an interference plate 2 for producing a nebula effect, a reflector 3 and at least one first lens 41 , the beam generator is placed on one side of the interference plate 2, the beam generator generates a light beam that is irradiated on one side of the interference plate 2 along the incident light path, the mirror 3 is placed on the other side of the interference plate 2, and at least one first lens 41 is located on the outgoing light path of the interference sheet 2, and the light beam emitted from one side of the interference sheet 2 passes through at least one first lens 41 to form a moving nebula level projection. The star projecting lamp provided in this embodiment also includes a star projector for generating star effects, and the star projection generated by the star projector is projected on the nebula projection to form a star projection. ...

Abstract

The invention discloses a starry sky projection lamp, and belongs to the field of projection lamps. The starry sky projection lamp comprises at least one light beam generator, an interference sheet used for generating a starry cloud effect, a reflector and at least one first lens, the light beam generator is arranged at one side of the interference sheet, the reflector is arranged at the other side of the interference sheet, the at least one first lens is located on an emergent light path of the interference sheet, and a light beam emitted from the interference sheet passes through the at least one first lens to form a moving star cloud hierarchical projection. According to the starry sky projection lamp, the light beam is amplified through the lens after being refracted, reflected and then refracted for multiple times, so that the generated starry sky is not too bright and dazzling, the soft feeling of the pattern transition position is better, and the layering sense of the starry sky is effectively enhanced.

Description

technical field [0001] The present invention relates to the field of projection lamps, in particular to a starry sky projection lamp and a nebula generation method used for the starry sky projection lamp. Background technique [0002] The star projection lamp is a projection device that can produce dynamic nebula effects. It is often used in homes, cars, entertainment venues, etc. as ambient lights. Star projection lamps usually produce dynamic nebula effects by irradiating light beams on a rotating interference disk, and can even simulate actions such as stars blinking. [0003] Chinese Patent Literature Publication No. CN101276523B discloses a projection device for producing a moving starry sky and cloud-like effects, including a device for producing cloud-like effects using at least one incoherent light source, and a device for producing motion-like effects using at least one coherent light source. Devices for the starry sky and devices for regulating and supplying elect...
