Abstract
Description
[Technical Field]
[0001] This utility model relates to the technical field of projection lamps, and in particular to a projection lamp with dual projection effects. [Background Technology]
[0002] An existing dual-projection lamp includes a first projection component and a second projection component mounted on a lamp holder. The first projection component includes an LED light source, a film located above the LED light source, a light-transmitting element, and a motor assembly that drives the film to rotate. The light-transmitting element is configured as a frosted cover or a lens. Light emitted from the LED light source passes sequentially through the film or the lens and is projected outwards. The second projection component includes a lamp body, a glass sheet located above the lamp body, and a lampshade. The glass sheet has a projection pattern. The lampshade includes multiple small convex lenses. Light emitted from the lamp body passes sequentially through the projection pattern and the small convex lenses and is projected outwards to form a star projection effect. The star projection effects are spaced apart on the projection effect formed by the first projection component, and the projection ranges of the two are approximately the same, with the star effect in a static state.
[0003] Since the projection ranges of the two projection components in the above structure are roughly the same, and the pattern of one projection light effect rotates in place while the other projection effect is static, the combination of the two projection light effects results in a monotonous projection effect, poor fusion of light effects, and a lack of dynamism.

Detailed Implementation Methods
[0028] To facilitate a better understanding of the purpose, structure, features, and effects of this utility model, the present utility model will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0029] like Figures 1 to 6 As shown, the dual projection lamp 100 of this utility model includes a lamp holder 1 and a first projection group 2 and a second projection group 3 installed on the lamp holder 1.
[0030] like Figure 1 and Figure 2 As shown, the lamp holder 1 includes a receiving cavity 11 and a first projection hole 12 and a second projection hole 13 communicating with the receiving cavity 11. The first projection group 2 and the second projection group 3 are both received in the receiving cavity 11. The projected light effect formed by the first projection group 2 passes through the first projection hole 12, and the projected light effect formed by the second projection group 3 passes through the second projection hole 13.
[0031] like Figure 2 and Figure 3As shown, the first projection group 2 includes a first lamp body 21 and at least one optical element located above the first lamp body 21. The optical element is configured as a film, glass plate, grating plate, corrugated plate, or optical lampshade. In this embodiment, the first projection group 2 includes a first optical element and a second optical element located above the first optical element. The first optical element is defined as a light-distributing lens 23, and the second optical element is defined as a first imaging assembly. The first imaging assembly includes at least a magnifying lens, a compensating lens, and a wide-angle lens, with one of the lenses defined as the first lens, and the diameter of the first lens defined as d1. The central axis of the first imaging assembly is defined as P1. The first imaging assembly is configured as an aurora cover, a condenser lens, or a multi-faceted lampshade. The light-distributing lens 23 transmits, refracts, or reflects light from the first lamp body 21. The first projection group 2 forms an outward projection effect, and the first projection group 2 forms a wide-angle projection. The projection angle of the first projection group 2 is defined as θ, 60° < θ ≤ 360°, preferably within the range of 60° < θ ≤ 180°. The projection range width of the first projection effect is defined as D1, and D1 is defined as the maximum width of the first projection effect. The center of the first projection effect is defined as A1. The first projection effect includes a first light effect and a second light effect surrounding the second light effect. The brightness of the first light effect is higher than the brightness of the second light effect, or the projection brightness of the two is the same. In this embodiment, the light distribution lens 23 is a projection sheet. A motor drives the projection sheet to rotate to form a dynamic projection light effect, or the motor stops working and the first projection light effect is stationary. The first projection effect includes a central projection area and a peripheral projection area surrounding the central projection area. The brightness of the central projection area is lower than the brightness of the peripheral projection area. The central area forms the first light effect, and the peripheral area forms the second light effect. The central axis of the first projection group 2 is defined as P3, and the area of the first projection light effect is defined as S1. In other embodiments, the film, the glass sheet, or the corrugated sheet includes a first projection area and a second projection area. The light transmittance of the first projection area is higher than that of the second projection area, and the colors of the first projection area and the second projection area are different. In some embodiments, the corrugated sheet includes a plurality of lenses spaced apart, the plurality of lenses including at least a first lens, a second lens and a third lens, a connecting recess is provided between the first lens and the second lens, the angle between one recess and the other recess is different, the first lens and the second lens have different refraction angles for light, and the second lens and the third lens have different refraction angles for light.
[0032] like Figure 2 , Figure 5 and Figure 6As shown, the second projection group 3 includes at least a second lamp body 31, a projection screen 32 located above the second lamp body 31, and a second imaging component 33 located above the projection screen 32. The second projection group 3 forms a second projection effect projected outwards. The second imaging component 33 includes a second lens, the diameter of which is defined as d1, and the ratio of d1 / d2 is in the range of 22%-48%, such that the area of the first projection effect is larger than the area of the second projection effect. The second projection group 3 forms an animation projection. The projection angle of the second projection is β, where 10° < β < 45°. The first projection effect and the second projection effect form a projection fusion, that is, the two projection effects overlap. The wide-angle projector effect of the first projection effect brings the user a large-scale immersive feeling, while the second projection effect is roughly located in the middle of the first projection effect, bringing the user a sense of focus and dynamism in the visual effect. The combination of the light effects of the two projection ranges brings a sense of immersion and focus, resulting in a realistic visual effect. The projection area of the second projection light effect is defined as S2, where S2 is less than 1 / 2 of S1. The projection width of the second projection effect is defined as D2, where D1 is greater than D2. The center of the second projection effect is A2. A1 and A2 may be located on the same plane or different planes. The distance between A1 and A2 is D3, where D3 = 0 or D3 ≤ (1 / 2D1 - 1 / 2D2), meaning the second projection effect always falls within the range of the first projection effect. In this embodiment, D3 < 110mm, resulting in a higher degree of blending between the two projection effects. The second projection effect is located in the middle of the first projection effect. The second projection effect is a video animation projection, which is located in the middle of the first projection effect. The central axis of the second projection group 3 is P4, and the distance between P3 and P4 ranges from 38mm to 185mm, making the center distance of the two projection effects closer and the product size smaller. The second projection effect is located in the first projection area. The video animation projection gradually becomes clearer, or the overlap position of the second projection effect and the first projection effect continuously changes. The overlap position between the second and first projected light effects continuously changes, or the second projected light effect gradually appears on top of the first projected light effect. By setting the color of the central area of the projection sheet to be darker and the color of the outer area to be lighter, the brightness of the central area of the first projected light effect is lower than the projection brightness of the outer area. This makes the projection effect more pronounced and the dynamic effect better when the second projected light effect is in the central area of the first projected light effect, resulting in a higher overall sense of unity and fusion between the two light effects.
[0033] In summary, the dual projection lamp of this utility model has the following beneficial effects:
[0034] (1) The first projection group 2 includes a first lamp body 21, a light distribution lens 23 located above the first lamp body 21, and a first imaging component located above the light distribution lens 23. The first projection group 2 forms a first projection effect projected outwards, forming a wide-angle projection. The projection angle of the first projection group 2 is defined as θ, where 60° < θ ≤ 360°. The second projection group 3 includes a second lamp body 31, a projection screen 32 located above the second lamp body 31, and a second imaging component 33 located above the projection screen 32. The second projection group 3 forms a second projection effect projected outwards, forming an animation projection. The projection angle of the second projection is β, where 10° < β < 45°. The first projection effect and the second projection effect form a projection fusion. That is, the two projection effects overlap. The wide-angle projector effect of the first projection effect brings the user a large-scale immersive feeling, while the second projection effect is roughly located in the middle of the first projection effect, bringing the user a sense of focus and dynamism in the visual effect. The combination of the light effects of the two projection ranges brings a sense of immersion and focus, resulting in a realistic visual effect.
[0035] (2) Define the projection width of the first projection effect as D1, the center of the first projection effect as A1, define the projection width of the second projection effect as D2, D1 is greater than D2, the center of the second projection effect is A2, and the distance between A1 and A2 is D3, D3 = 0 or D3 ≤ (1 / 2D1 - 1 / 2D2). The effect ensures that the animation is projected in the middle of the comparison of the first projection light effect, resulting in better visual effect and better overall sense and integration of the picture.
[0036] (3) The first projection effect includes a central projection area and an outer projection area surrounding the central projection area. The brightness of the central projection area is lower than that of the outer projection area, so that when the second projection light effect is in the middle area of the first projection light effect, the projection effect is more significant, the dynamic effect is better, and the overall sense of the two light effects is higher.
[0037] (4) The second projection effect is a video animation projection, which is located in the middle of the first projection effect. The video animation projection gradually becomes clearer or the overlapping position of the second projection effect and the first projection effect changes continuously, resulting in a stronger sense of dynamic immersion.
[0038] The above detailed description is only a description of the preferred embodiment of this utility model and is not intended to limit the patent scope of this utility model. Therefore, all equivalent technical changes made using the content of this invention's specification and illustrations are included within the patent scope of this invention.
