Example Embodiment
[0031] Example 1
[0032] Such as figure 1 As shown, a projection lamp that simulates the sky effect includes a housing 100 and a first light-emitting component 200 arranged in the housing 100. The first light-emitting assembly 200 includes a first light source 210 that generates a first light, a first ground glass 220 and a convex lens 230 arranged on the optical path of the first light, the three are sequentially arranged in the housing 100, the first The first light emitted by a light source 210 is projected onto a surface through the first ground glass 220 and the convex lens 230 to present a cloud effect.
Example Embodiment
[0033] Example 2
[0034] The difference between this embodiment and embodiment 1 lies in figure 2 As shown, the projection lamp that simulates the sky effect further includes a driving device 400. The first ground glass 220 is in transmission connection with the driving device 400. When the first ground glass 220 moves under the control of the driving device 400, the first light source 210 emits The first rays of light passing through the first ground glass 220 and the convex lens 230 are projected onto a surface to present a changing cloud effect. The first frosted glass 220 rotates under the driving of the driving device 400. Due to the irregularity of the wrinkles on the surface of the first frosted glass 220, the effect of the first light rays projecting on a surface through the first frosted glass 220 shows irregular movement and no The regular shape changes further improve the fidelity of the simulated sky effect.
Example Embodiment
[0035] Example 3
[0036] The difference between this embodiment and embodiment 1 lies in image 3 As shown, the projection lamp that simulates the sky effect further includes a second light-emitting assembly 300, which includes a second light source 310 that generates a second light and a grating sheet arranged on the light path of the second light 320. The second light emitted by the second light source 310 is projected onto a surface through the grating sheet 320 to present a star effect. The second light passing through the grating sheet 320 presents a star-like pattern on a surface, thereby realizing a realistic starry sky in the room.
