DETAILED DESCRIPTION

[0031] In order to make the technical problems solved by the present application, the technical solutions adopted and the technical effects achieved more clear, the technical solutions of the embodiments of the present application will be further described in detail below with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0032] In the description of the present application, unless otherwise explicitly specified and limited, the term "connected" should be understood broadly, and the term "fixed" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0033] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0034] As attached Figure 1 , 2 As shown in Figures 1 and 3, a small-volume courtyard water ripple light includes a disturbance lens 1, a front cover 2, a die-cast heat sink 3, an effect module 4, a power module 5, and a rear cover 6.

[0035] The disturbance lens 1 is rectangular, and at least one side of it includes a plurality of plano-convex lenses with continuous smooth transitions or discontinuous transitions; the disturbance lens 1 is installed in a groove on the upper part of the front cover 2;

[0036] Effect module 4 includes, in sequence, a second disturbance lens 41, a driving component, a scattering lens 43, a glass bracket 431, a support plate 44, an LED light source 45, and a heat sink 46, with the LED light source 45 mounted on the heat sink 46.

[0037] The drive assembly includes a drive motor 421 and a drive mechanism. The drive mechanism includes a movable plate 427, two parallel guide rods 424, fixed brackets 425 located at both ends of the guide rods, a plastic bushing 426, a rotating flange 422, and a drive rod 423. The movable plate 427 is provided with a disturbance mirror mounting slot 4271 and a drive rod movable slot 4272.

[0038] The drive motor 421 and the fixed frame 425 in the drive assembly are mounted on the support plate 44; two parallel guide rods 424 are located between the two sets of fixed frames 425 respectively, and the movable plate 427 is movably mounted on the two parallel guide rods 424 through the plastic bushing 426.

[0039] After installation, the drive motor 421 is located below the scattering lens 43. The drive motor 421 drives the second disturbance lens 41 to perform reciprocating linear motion via the rotating flange 422 and the drive rod 423. The principle of the drive motor 421 driving the second disturbance lens 41 is a centering crank-slider mechanism. The distance D1 between the scattering lens 43 and the LED light source 45 is less than 10mm. The second disturbance lens 41 and the first disturbance lens 1 are rectangular lenses of the same material but different sizes. The area of ​​the second disturbance lens 41 is smaller than the area of ​​the first disturbance lens 1.

[0040] The scattering lens 43 is a fixed lens between the perturbation lens two 41 and the LED light source 45.

[0041] As described above, the present embodiment realizes a small volume of the garden water ripple lamp mainly through the following two conditions:

[0042] 1-the distance D1 between the scattering lens 43 and the LED light source 45 is less than 10mm; that is, the LED light source 45 does not need to be matched with a secondary optical lens, because if matched with a secondary optical lens, although the effect of converging light can be achieved, the length of the optical system of the lamp will be certainly lengthened, and once lengthened, the volume will be certainly much larger than the present embodiment. The present embodiment considers that in order to reduce the volume, the scattering lens 43 is directly arranged close to the LED light source 45, so that the light emitted by the LED light source 45 can pass through the scattering lens 43, and the purpose of extremely reducing the height of the lamp is achieved.

[0043] 2-the driving motor 421 is located below the scattering lens 43, and the principle of driving the perturbation lens two 41 is the concentric crank slider mechanism mode. As a person skilled in the art can understand, for the linear motion of a single optical lens, such as the CMY component in a stage lamp, the position of the driving motor 421 is on both sides of the single optical lens, and then auxiliary belts or guide rails are used to achieve. However, when the driving motor 421 is located on both sides, the width of the driving mechanism will be obviously increased; therefore, the concentric crank slider mechanism mode is adopted in the present embodiment, so that the driving motor 421 can be directly fixed below the scattering lens 43 instead of the side, and the purpose of extremely reducing the width of the lamp is achieved.

[0044] As a preferred embodiment, the distance D2 between the scattering lens 43 and the perturbation lens two 41 is less than 15mm, the distance D3 between the perturbation lens two 41 and the perturbation lens one 1 is less than 25mm, and the area of the perturbation lens two 41 is less than 50% of the area of the perturbation lens one. The beneficial effect of this embodiment is that the perturbation lens two 41 needs to do linear reciprocating motion inside the lamp, and in the condition of satisfying the light receiving from the scattering lens 43, the smaller the volume is, the better; at the same time, in order to balance the light receiving and the volume of the lamp, through optical simulation, the distance D2 between the scattering lens 43 and the perturbation lens two 41 is less than 15mm, which is the most reasonable. Because the value of D2 is too large, the area of the perturbation lens two 41 must be larger, which will cause the stroke of the linear reciprocating motion of the perturbation lens 41 to be reduced. At the same time, the distance D3 between the perturbation lens two 41 and the perturbation lens one 1 is less, the height of the whole lamp is smaller, and the volume is smaller, and through optical simulation, the distance D3 between the perturbation lens two 41 and the perturbation lens one 1 is less than 25mm, which is the most reasonable.

[0045] As a preferred embodiment, the center of the surface of the perturbation lens 1 is a transparent area, and the periphery is a silk-printed area. The beneficial effect of this embodiment is that only the part of the outgoing light on the perturbation lens 1 is retained, and the part of the light that is not outgoing is blocked, which is more beneficial for the appearance.

[0046] As a preferred embodiment, as shown in FIG. 4, the scattering lens is a diamond glass lens or a wood grain glass lens. The diamond glass lens is a lens with high and low particles on one side. The contour projection line of the wood grain glass lens is a plurality of regularly arranged spline curves, and the interval L between the adjacent two spline curves is less than 2 mm. The beneficial effect of this embodiment is that Figure 4 、 5 The diamond glass lens or the wood grain glass lens is used, and the projected image tends to be a flowing water effect.

[0047] The diamond glass lens or the wood grain glass lens is used, and the projected image tends to be a flowing water effect.

[0048] As a preferred embodiment, the rotating flange 422 is in a "7" shape structure, one end of the rotating flange 422 is fixed on the motor shaft of the driving motor 421, and the other end is fixed with the driving rod 423. The driving motor 421 drives the rotating flange 422 to rotate, and the rotating flange 422 drives the driving rod 423 to rotate around the center axis of the driving motor 421, and the driving rod 423 drives the perturbation lens two 41 on the movable plate 427 to move linearly back and forth through the perturbation lens two installation groove 4271.

[0049] As a preferred embodiment, the scattering lens 43 can be a circular or rectangular lens. Since the purpose of the scattering lens is to disperse light, the shape of the scattering lens 43 can be selected according to the size of the reserved space in the structure design.

[0050] The LED light source 45 emits light, which passes through the scattering lens 43, then passes through the movable perturbation lens two 41, and finally passes through the perturbation lens one 1 to form a flowing water effect.
