[0002] LED spotlights are mainly used for decorative lighting and to outline large buildings. Their technical parameters are roughly similar to those of LED projection lamps. Compared with the circular structure of LED projection lamps, the heat dissipation device of the strip structure of LED projection lamps appears to be easier to handle.

[0003] The field of projection lamps has developed to the point where projection lamps with rolling structures have appeared. For example, application number 201510332599.3 discloses a projection lamp equivalent to a rolling snowflake, which includes a projection device and a bracket connected to the bottom of the projection device. In this structure, a motor is fixed in a shell, and the rotating shaft of the motor is connected to a focusing lens ball. The rotating shaft and the connecting rod portion of the connecting fixing are radially opposite to the center of the focusing lens ball, that is, the rotating shaft and the connecting rod portion are coaxially arranged. This lamp projects movable light, and its lighting effect is more gorgeous, which can create different atmospheres. However, there are the following technical problems at the same time. In this projection lamp, the rotating shaft and the connecting rod portion are installed on the shell at the same time, that is, both symmetrical ends are connected to the shell. Since the rotating shaft and the connecting rod portion are coaxially arranged, the focusing lens ball and the shell have two connection points.

[0041] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0042] The present invention improves the existing projection lamp, and aims to simplify the installation structure between the focusing lens ball and the housing, reduce the requirements of each component on the processing and installation accuracy, improve the processing and installation efficiency of the components, and reduce the cost.

[0043] like Figures 1 to 5 As shown, the projection lamp with rolling light effect of the present invention comprises a housing 10 , a lampshade 20 , a light emitting component 30 , a focusing lens ball 40 and a motor 50 .

[0044] The projection shape of the shell 10 is a "cross" shape, which is an internal hollow structure and has a "cross" shaped opening on its front face. The lampshade 20 is a light-transmitting structure made of light-transmitting material, which is covered at the opening of the shell 10 and is fixedly connected to the shell 10 by screws and other connecting parts. The middle part of the lampshade 20 protrudes from the inside to the outside to form a spherical convex portion 21. The light-emitting component 30 is arranged in the middle part of the shell 10. A fixed shaft 11 is arranged between the light-emitting component 30 and the shell 10. One end of the fixed shaft 11 is fixedly connected to the light-emitting component 30, and the other end is connected to the shell 10. The light projection direction of the light-emitting component 30 is aligned with the lampshade 20. The focusing lens ball 40 is a spherical structure with a hollow interior. In order to facilitate the installation of the light-emitting component 30, the focusing lens ball 40 is surrounded by two hollow left and right hemispheres. A plurality of connected circular convex lens portions 41 are distributed on the inner surfaces of the left and right hemispheres. The focusing lens ball 40 is arranged in the shell 10 and The condenser lens ball 40 extends into the spherical raised portion 21, and a shaft sleeve 42 is convexly provided on the outer surface of the condenser lens ball 40. The shaft sleeve 42 is formed by parts respectively located on the left and right hemispheres. The axis of the shaft sleeve 42 coincides with the center of the circle of the condenser lens ball 40. The light-emitting component 30 is located in the condenser lens ball 40, and the fixed shaft 11 is located in the shaft sleeve 42 and is relatively fixed to the shaft sleeve 42. The motor 50 is fixed in the shell 10 and is transmission-connected to the shaft sleeve 42. A circuit board 12 is also installed in the shell 10. The circuit board 12 is electrically connected to the light-emitting component 30 and the motor 50 at the same time. A power switch 13 is provided on the circuit board 12 for controlling the motor 50 and the light-emitting component 30. The power switch 13 passes through the shell 10 and is fixed to the shell 10. A wiring plug 14 electrically connected to the circuit board 12 and connected to the shell 10 is also provided below the circuit board 12 for electrically connecting to an external power supply. The wiring plug 14 passes through the shell 10 and is fixed to the shell 10.

[0045] During operation, the motor 50 drives the focusing lens ball 40 to rotate around the axis of the shaft sleeve 42 in the housing 10, and the stationary light-emitting component 30 projects light onto the lampshade 20. The light is projected onto the convex lens portion 41 in the moving focusing lens ball 40, and forms a moving light spot similar to a snowflake or other shape on the projected object outside the focusing lens ball 40.

[0046] In this structure, a single-point fixed connection is formed between the focusing lens ball 40 and the outer shell 10 through a fixed shaft 11, and the shaft sleeve 42 plays a role of support and rotation. The single-point connection makes the processing and installation accuracy requirements of each component of the projection lamp lower, which is convenient for the processing and installation of each component, and also simplifies the structure, reducing the cost to a certain extent.

[0047] Based on the above structure, the present invention makes further improvements and refinements thereto.

[0048] like Figures 3 to 5As shown, the shaft sleeve 42 is provided with a transmission sleeve 43 fixedly connected thereto. The transmission sleeve 43 is fixed relative to the housing 10 and the lampshade 20 in its radial direction. The transmission sleeve 43 is connected to the motor 50 through a gear 51 and the shaft sleeve 42 can rotate synchronously with the transmission sleeve 43.

[0049] Preferably, a ring gear 44 is fixedly connected to one end of the transmission sleeve 43, the inner diameter of the ring gear 44 is larger than the inner diameter of the transmission sleeve 43, and a buttress 43a is formed between the transmission sleeve 43 and the ring gear 44, a locating bearing 44a is arranged in the ring gear 44, the locating bearing 44a is abutted against the buttress 43a and respectively pressed against the ring gear 44 and the fixed shaft 11, a gear 51 is arranged on the output shaft of the motor 50, here, the output shaft of the motor 50 is arranged parallel to the fixed shaft 11, and the gear 51 is meshedly connected with the ring gear 44.

[0050] The entire shaft sleeve 42 is formed by the parts respectively located on the two hemispheres. The transmission sleeve 43 fixes the two convex sleeves to form the shaft sleeve 42, and at the same time plays the role of fixing the two hemispheres, thereby improving the integrity of the focusing lens ball 40. The setting of the positioning bearing 44a improves the stability of the ring gear 44 and the transmission sleeve 43 in the radial direction, making the ring gear 44 and the transmission sleeve 43 more stable and flexible when rotating. The positioning bearing 44a is against the abutment 43a, and it is not easy to turn and jump. The transmission sleeve 43 and the motor 50 are connected to the ring gear 44 through the gear 51, thereby realizing the smooth rotation of the focusing lens ball 40, and the gear 51 also plays the role of supporting the ring gear 44, thereby improving the stability of the focusing lens ball 40.

[0051] Of course, the transmission between the transmission sleeve 43 and the motor 50 can also be achieved through other transmission methods, for example, through a worm gear.

[0052] like Figures 3 to 5 As shown, a positioning ring 45 is sleeved on the transmission sleeve 43, and the positioning ring 45 is located between the motor 50 and the lampshade 20 and remains relatively fixed with the two. The transmission sleeve 43 can rotate in the positioning ring 45, that is, the positioning ring 45 is directly or indirectly against the motor 50 and the lampshade 20, so that the positioning ring 45 remains fixed.

[0053] In this structure, the fixed shaft 11 is stationary, and the sleeve 42 and the fixed shaft 11 are supported only by a supporting point, namely, a positioning bearing 44a between the transmission sleeve 43 and the fixed shaft 11. This causes the focusing lens ball 40 to be unstable and easy to shake in the outer shell 10. By setting a positioning ring 45, another supporting point is added to the transmission sleeve 43, so that the entire transmission sleeve 43 forms a two-point support, thereby improving the stability of the focusing lens ball 40. The positioning ring 45 is completely surrounded by the outer periphery of the transmission sleeve 43, and has a better positioning effect on the transmission sleeve 43.

[0054] Furthermore, a support plate 60 is provided between the motor 50 and the positioning ring 45. One end of the support plate 60 abuts against the motor 50, and the other end is provided with an arc groove 61. The positioning ring 45 is located in the arc groove 61 and abuts against the support plate 60. A baffle plate 62 fixedly connected to the support plate 60 is provided on one side of the arc groove 61. A limiting boss (not shown in the figure) is provided on the transmission sleeve 43, and the positioning ring 45 abuts against the baffle plate 62 and the limiting boss respectively.

[0055] Figures 3 to 6 A main cover plate 70 is fixedly provided at the outlet of the housing 10, and the main cover plate 70 is close to the lampshade 20. A limit seat 71 is fixedly provided on the inner surface of the main cover plate 70, and a limit groove 72 is provided on the limit seat 71. The positioning ring 45 is located in the limit groove 72 and abuts against the limit seat 71. A stop block 73 is provided on one side of the limit seat 71, and the positioning ring 45 abuts against the stop block 73.

[0056] By providing the support plate 60 and the limit seat 71, two relative fixed points are formed on the outer surfaces of both sides of the positioning ring 45, thereby playing a role in fixing the positioning ring 45, improving the stability of the positioning ring 45 in the radial direction, and making the supporting effect of the positioning ring 45 better. The baffle 62, the limit boss and the block 73 all play a role in limiting the movement of the positioning ring 45 in the axial direction, thereby ensuring the stability of the positioning ring 45 in the axial direction.

[0057] It is worth mentioning that the above-mentioned limiting seat 71 can also be directly set on the lampshade 20. When the lampshade 20 is fixedly connected to the housing 10, the limiting seat 71 can directly abut against the positioning ring 45.

[0058] like Figure 3 As shown, an arc-shaped positioning sleeve 63 is provided at one end of the support plate 60, and mounting portions 63a are extended from both ends of the arc-shaped positioning sleeve 63 respectively. A mounting seat 15 is provided on the inner surface of the outer shell 10 and the motor 50 is placed in the mounting seat 15. The motor 50 is located in the arc-shaped positioning sleeve 63 and the mounting portion 63a is fixedly connected to the mounting seat 15 by screws and other connecting parts.

[0059] The motor 50 can be directly fixed on the mounting base 15 through the arc-shaped positioning sleeve 63 without additional fixing of the motor 50 and the mounting base 15, thereby facilitating the installation of the motor 50. At the same time, the support plate 60 is fixed to the housing 10, which also improves the stability of the support plate 60 itself.

[0060] like Figure 3 , Figure 4 , Figure 5 , Figure 7As shown, a sub-cover plate 80 is fixedly arranged in the outer shell 10, and a limit plate 81 perpendicular to the sub-cover plate 80 is fixedly arranged on the inner surface of the sub-cover plate 80, and a limit hole 82 is arranged on the limit plate 81. A limit shaft 46 coaxial with the shaft sleeve 42 is convexly arranged on the outer surface of the focusing lens ball 40, and the limit shaft 46 is also formed by two parts convexly arranged on the two hemispheres respectively. A shaft cover 47 is sleeved on the limit shaft 46, and the entire limit shaft 46 is plug-connected with the shaft cover 47. The shaft cover 47 and the limit shaft 46 extend into the limit hole 82 and are separated from the limit hole 82. That is to say, under normal circumstances, the shaft cover 47 and the limit plate 81 are in a non-contact state.

[0061] The focusing lens ball 40 forms two supporting points through the positioning bearing 44a and the positioning ring 45, but the two supporting points are located on the same side of the focusing lens ball 40. In this case, when the outer shell 10 moves or is hit, the focusing lens ball 40 will shake, which will have a great impact on the two supporting points of the focusing lens ball 40 and the overall stability of the focusing lens ball 40.

[0062] By setting the limit plate 81 to cooperate with the limit shaft 46, when the focusing lens ball 40 shakes, the limit plate 81 can block the limit shaft 46 to prevent the focusing lens ball 40 from shaking in a large range, thereby improving the stability of the focusing lens ball 40 when the shell 10 is hit or moved.

[0063] It is worth noting that the limiting shaft 46 does not have a supporting function, but only plays an auxiliary role in preventing the focusing lens ball 40 from shaking in a large range.

[0064] like Figure 3 , Figure 4 As shown, a fixing seat 16 is disposed in the housing 10 , and the fixing seat 16 is fixedly connected to the housing 10 via connecting members such as screws. A fixing sleeve 16 a is disposed on the fixing seat 16 , and one end of the fixing shaft 11 is plugged and fixedly connected to the fixing sleeve 16 a .

[0065] With this structure, the fixed shaft 11 and the housing 10 can be flexibly assembled and disassembled, and the plug-in connection also provides a better fixing effect of the fixed shaft 11.

[0066] like Figure 3 As shown, the light emitting assembly 30 includes a lamp holder 31 , a lamp board 32 and a connecting board 33 .

[0067] The lamp holder 31 is in a "V" shape as a whole, and two adjacent and obliquely arranged mounting grooves are arranged on its outer surface. There are two lamp boards 32, and the two lamp boards 32 are respectively embedded in the two mounting grooves and fixedly connected to the lamp holder 31. Each lamp board 32 is provided with a light-emitting element 32a, and the light-emitting element 32a is electrically connected to the circuit board 12. Preferably, the light-emitting element 32a is an LED lamp. The connecting plate 33 is fixedly connected to one side of the lamp holder 31, and a connecting sleeve 33a is fixedly provided on the outer surface of the connecting plate 33. The other end of the fixed shaft 11 is plugged and fixedly connected to the connecting sleeve 33a.

[0068] The lamp holder 31 is plug-connected to the fixed shaft 11 to facilitate assembly and disassembly of the fixed shaft 11 and the lamp holder 31 . The structure of the lamp holder 31 and the connection structure between the lamp panel 32 and the lamp holder 31 may be other structures and are not limited to this one.

[0069] The working principle of the present invention is as follows:

[0070] When in use, the projection lamp is electrically connected to an external power source via the wiring plug 14, and then the power switch 13 is turned on, and the circuit board 12 supplies power to the motor 50 and the light-emitting element 32a respectively.

[0071] The motor 50 drives the focusing lens ball 40 to rotate with the axis of the sleeve 42 as the center. The light-emitting element 32a emits light and is projected onto the external projected object through the convex lens part 41 on the focusing lens ball 40 and the lampshade 20. As the focusing lens ball 40 rotates, moving light spots similar to snowflakes are formed on the surface of the projected object.

[0072] When the projection lamp is moved or hit, the limiting shaft 46 contacts the limiting plate 81 to prevent the focusing lens ball 40 from shaking in a large range, so as to ensure the stability of the focusing lens ball 40.

[0073] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
